A Comparative Evaluation of Diffractive Trifocal and New Refractive/Extended Depth of Focus Intraocular Lenses for Refractive Lens Exchange.

PURPOSE: To evaluate and compare the visual performance and quality of life (QOL) associated with refractive/extended depth of focus (EDOF) intraocular lenses (IOLs) and diffractive trifocal IOLs in refractive lens exchange patients. MATERIALS AND METHODS: This was a comparative interventional study of patients undergoing implantation of Lucidis (Swiss Advanced Vision, SAV­IOL SA, Neuchâtel, Switzerland) or AT LISA tri 839MP (Carl Zeiss Meditec AG, Germany) IOLs. Near, intermediate, and distance best corrected and uncorrected visual acuities were collected at 1 and 3 months postoperatively. The vision-related QOL was evaluated 1 and 3 months after surgery, using the National Eye Institute Visual Function Questionnaire-14 (VF-14 QOL questionnaire). RESULTS: A total of 74 patients underwent refractive lens exchange and IOL implantation, with 38 patients in the EDOF group and 36 in the trifocal group. Among all visual acuities, uncorrected near visual acuity was statistically significantly better with the Lucidis IOL at the first month (p = .02) and diminished at the third-month visit (p = .16). When we compared the VF-14 QOL questionnaire scores, reading small print, reading a newspaper or book, and driving at night were statistically significantly better in the Lucidis group at the first month (p = .00, for each). That difference persisted only in driving at night at the third-month visit (p = .04). Reading small print, driving at night, and doing fine handwork were the most difficult tasks in the AT LISA group at the first month, and only driving at night remained so at the third-month visit. CONCLUSIONS: The refractive results and visual outcomes at all distances of EDOF and trifocal IOLs were highly satisfactory. However, the EDOF design in the Lucidis IOL achieves lower rates of glare in the early period after refractive lens exchange.

Impact of Cataract Surgery on Functional Balance Skills of Adults

Objectives: To investigate the impact of phacoemulsification surgery and intraocular lens implantation on the functional balance skills of adults. Materials and Methods: This prospective study included patients with cataract who were recommended phacoemulsification surgery and intraocular lens implantation between May and October 2016. The Berg Balance Scale and Tinetti Gait and Balance Test were performed by a physical therapy specialist before and 1 month after surgery. Patients were analyzed in terms of age, visual acuity, and balance. Balance scores before and after cataract surgery were compared. We also compared patients with high (≤2 LogMAR) and low (>2 LogMAR) visual acuity. P values below 0.05 were accepted as statistically significant. Results: Fifty-one patients (27 female and 24 male, mean age 66.96 years) were included in the study. One month after surgery, the patients' Berg Balance scores and Tinetti Gait and Balance scores were increased by 3.60±5.00% and 4.14±6.55%, respectively. Postoperative increase in visual acuity was significantly greater in the 16 patients with visual acuity less than 0.05 (>2 LogMAR) (p=0.036), but balance scores were not significantly different. Conclusion: Visual acuity is significantly improved one month after cataract surgery, which also leads to significant increases in low functional balance scores among patients with poorer vision. The rapid increase in vision after cataract surgery enhances balance skills, resulting in safer mobility and increased quality of life.

Comparison of Mix-and-Match Implanted Bifocal IOLs and Bilateral Implanted Trifocal IOLs After Femtosecond Laser-Assisted Cataract Surgery.

PURPOSE: To compare the visual performance of mix-and-match implanted bifocal intraocular lenses (IOLs) and bilateral implanted trifocal IOLs from the same manufacturer with the same IOL platform after femtosecond laser-assisted cataract surgery (FLACS). METHODS: This prospective, comparative, non-randomized study included patients who underwent FLACS (LenSx; Alcon Laboratories, Inc., Fort Worth, Texas) with bilateral implantation of bifocal IOLs (ReSTOR +2.50 D/+3.00 D; Alcon Laboratories, Inc.) or trifocal IOLs (PanOptix; Alcon Laboratories, Inc.). Visual acuities, manifest refraction, defocus curve, contrast sensitivity, quality of life measured by the Visual Function Index (VF-14), and spectacle independence were assessed at 6 months after surgery. RESULTS: A total of 70 eyes of 35 patients were included in this study. There was no difference in patient demographics and preoperative measurements between groups (P > .05). There was no difference in uncorrected distance visual acuity and corrected distance visual acuity outcomes between groups (P > .05), but uncorrected intermediate visual acuity and uncorrected near visual acuity outcomes were significantly better in the PanOptix group (P < .01). Correspondingly, the binocular defocus curve of the PanOptix IOLs showed significantly better visual acuity between -1.00 and -3.00 diopters compared to the ReSTOR IOLs (P < .05). The PanOptix group showed higher contrast sensitivity scores than the ReSTOR group for 12 and 18 spatial frequencies in photopic conditions and for 18 spatial frequencies in mesopic conditions (P < .05). The average VF-14 score was similar between groups (P = .78). None of the patients required spectacles. CONCLUSIONS: Bilateral implanted PanOptix IOLs seem to provide better intermediate and near vision, defocus curve, and contrast sensitivity compared to mix-and-match implanted ReSTOR IOLs. However, similar vision-related quality of life and spectacle independence were achieved with both IOLs. [J Refract Surg. 2019;35(9):559-564.].

Influence of angle kappa and angle alpha on visual quality after implantation of multifocal intraocular lenses.

PURPOSE: To assess the influence of angle kappa (κ) and angle alpha (α) on visual quality after multifocal intraocular lens (IOL) implantation. SETTING: Eye Hospital, Wenzhou Medical University, Wenzhou, Zhejiang, China. DESIGN: Prospective case series. METHODS: Patients with cataract had phacoemulsification with TECNIS Symfony IOL implantation. The preoperative angle κ and angle α were measured using the iTrace device. Distance, intermediate, and near visual acuities were recorded 3 months postoperatively. The Optical Quality Analyzing System was used to measure the objective scatter index (OSI), modulation transfer function (MTF) cutoff frequency, and Strehl ratio. A patient questionnaire was also administered. RESULTS: The study comprised 29 patients (57 eyes). Monocularly, the mean postoperative logarithm of the minimum angle of resolution (logMAR) uncorrected distance, intermediate, and near visual acuities were 0.03 ± 0.09 (SD), 0.05 ± 0.11, and 0.11 ± 0.09, respectively. The mean postoperative logMAR corrected distance, distance-corrected intermediate, and distance-corrected near visual acuities were -0.01 ± 0.05, 0.04 ± 0.09, and 0.11 ± 0.08, respectively. The mean OSI, MTF cutoff, and Strehl ratio were 1.27 ± 0.84, 32.03 ± 10.80 cycles per degree, and 0.17 ± 0.05, respectively. The OSI (r = 0.398, P = .005), MTF (r = -0.437, P = .002), and Strehl ratio (r = -0.419, P = .003) values were significantly correlated with angle κ. There was no correlation with angle α. CONCLUSIONS: Angle κ affected the objective visual quality multifocal after IOL implantation. The decision to implant a multifocal IOL should be carefully considered for patients with a large angle κ.

Evaluation of quality of life after implantation of a new trifocal intraocular lens.

PURPOSE: To evaluate the vision-related quality of life (QOL) after implantation of a new trifocal intraocular lens (IOL), by using the National Eye Institute Visual Function Questionnaire-14 (VF-14 QOL questionnaire). SETTING: Baskent University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey. DESIGN: Prospective noncomparative case series. METHODS: Consecutive patients who had a new trifocal IOL (PanOptix) bilaterally implanted were included in the study. The vision-related QOL was assessed 3 months after the surgery in the second eye. The VF-14 QOL questionnaire was used, with a grading scale of 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. A subgroup of 14 patients, with an interval of at least 3 months between the surgery in the first eye and the surgery in the fellow eye, were also interviewed 3 months after the monocular IOL implantation. In this subgroup, the QOL with monocular and binocular implantation was compared. RESULTS: The study comprised 48 patients. Reading small print, driving at night, and doing fine handwork were the most difficult tasks to perform, with the mean values of the VF-14 QOL questionnaire being 0.94 ± 0.81 (SD), 0.89 ± 0.68, and 0.64 ± 0.67, respectively. Binocular implantation was associated with improvement in vision-related QOL when compared with monocular implantation, with significant differences in doing fine handwork such as sewing (P = .02) and using a computer (P = .03). CONCLUSIONS: With mean values of 1.00 or lower for each question, the results of the VF-14 QOL questionnaire indicated that patients who have the new trifocal IOL bilaterally implanted have an overall high satisfaction rate and a high vision-related QOL.

In Vivo Measurement of Longitudinal Chromatic Aberration in Patients Implanted With Trifocal Diffractive Intraocular Lenses.

PURPOSE: To measure the longitudinal chromatic aberration (LCA) by both psychophysical methods and in vivo double-pass retinal imaging in patients bilaterally implanted with trifocal diffractive intraocular lenses (IOLs). METHODS: Measurements were performed with a polychromatic adaptive optics system provided with a supercontinuum laser, a Hartmann-Shack wavefront sensor, a deformable mirror, a motorized Badal system, a pupil monitoring system, a double-pass retinal imaging channel, and a psychophysical channel with monochromatically illuminated stimuli. Ten patients (20 eyes) bilaterally implanted with hydrophilic trifocal diffractive IOLs (POD F [FINeVision]; PhysIOL, Liege, Belgium) participated in the study. Measurements were performed in both eyes at three different viewing distances (0.00, +1.75, and +3.50 diopters [D]). Subjective best focus of monochromatic stimuli at five wavelengths (480 to 700 nm) was obtained using the Badal system. Best focused images of through-focus double-pass image series were obtained at three wavelengths (480 to 700 nm). LCA was computed from chromatic difference of focus curves (objective and subjective) as the difference between 480 and 700 nm at near, intermediate, and far. RESULTS: The average subjective LCA was 0.82 ± 0.05 D for far, 0.27 ± 0.15 D for intermediate, and 0.15 ± 0.15 D for near. The average objective LCA was 0.72 ± 0.10 D for far, 0.19 ± 0.15 D for intermediate, and 0.07 ± 0.17 D for near. CONCLUSIONS: Objective LCA was lower than subjective LCA, which was in agreement with previous studies on patients with phakic and monofocal IOLs. In vivo measurements of LCA enable understanding of the relative contribution of refractive and diffractive LCA and will eventually optimize IOL designs to improve polychromatic image quality.

Changes in quality of life shortly after routine cataract surgery.

OBJECTIVE: To perform a pilot study to explore use of a generic patient-reported outcome measure to assess patient-perceived improvements in quality of life within 2-4 weeks of routine cataract surgery and to explore differences after first or second eye surgery. Secondary analysis explored effects of gender and ethnicity. DESIGN: Prospective observational study. PARTICIPANTS: Consecutive patients attending a weekly nurse-led postoperative clinic. METHODS: The Glasgow Benefit Inventory (GBI), a validated, postinterventional questionnaire (not specific to one particular medical or surgical intervention), was administered. Mean scores were calculated. Scores were compared when patients were grouped by first or second eye, and by gender or ethnicity (unpaired t test). Scores potentially range from +100 (maximum benefit) to -100 (maximum detriment). RESULTS: The GBI was administered 113 times to 109 patients (4 patients were seen after both first and second eye surgery). Mean overall score was +22.8 (median +19.4; SD 19.7; 95% CI +19.2 to +26.4). Mean (SD) subscores were +30.5 (25.3), +17.8 (26.7), and -3.1 (19.9) for general, social support, and physical health subdomains, respectively. Total benefit scores were not significantly different for first or second eye surgery, or across gender (p > 0.3). Scores for patients of African (including African Caribbean) ethnicity were significantly higher than those obtained from European patients (p = 0.002). CONCLUSIONS: Patients reported significant improvements in quality of life even a few weeks after cataract surgery, as assessed by the GBI. Second eye surgery appeared to confer similar benefit to first eye surgery. The significant difference in scores between ethnic groups invites further investigation.

Trifocal Intraocular Lens Implantation to Treat Visual Demands in Various Distances Following Lens Removal.

PURPOSE: To evaluate visual and refractive outcomes after implantation of a trifocal intraocular lens (IOL). DESIGN: Prospective, nonrandomized noncomparative case series. METHODS: setting: Department of Ophthalmology, Goethe University, Frankfurt/Germany. patient or study population: Twenty-seven patients (54 eyes) who had bilateral implantation of the AT LISA trifocal IOL (AT LISA tri839MP; Carl Zeiss Meditec, Jena, Germany) pre-enrollment. Exclusion criteria were previous ocular surgeries excluding cataract surgery and refractive lens exchange, irregular corneal astigmatism of >1.5 diopter, and ocular pathologies or corneal abnormalities. Intervention or Observation Procedure(s): Postoperative examination at 1 and 3 months included manifest refraction; monocular and binocular uncorrected (UCVA) and distance-corrected (DCVA) visual acuity in 4 m, 80 cm, and 40 cm; slit-lamp examination; and tomography. At 3 months defocus testing, binocular contrast sensitivity (CS) under photopic and mesopic conditions, and a questionnaire on subjective quality of vision, optical phenomena, and spectacle independence were performed. MAIN OUTCOME MEASURE(S): Three-months-postoperative monocular and binocular UCVA and DCVA in 4 m, 80 cm, and 40 cm (logMAR); defocus curve; CS; and quality-of-vision questionnaire results. RESULTS: Mean spherical equivalent was 0.05 ± 0.32 D 3 months postoperatively. Binocular UCVA at distance, intermediate, and near was -0.1 ± 0.1 logMAR, 0.0 ± 0.1 logMAR, and 0.0 ± 0.1 logMAR, respectively. Despite some optical phenomena, 92% of patients would choose the same IOL again. CONCLUSION: Evaluation of a trifocal IOL showed good VA (0.1 logMAR or better) at far, intermediate, and near distance; high patient satisfaction despite some optical phenomena; and high spectacle independence 3 months postoperatively.

Health-related quality of life after cataract surgery with the phacoemulsification technique and intraocular lens implantation.

PURPOSE: Disease-specific instruments have shown significant gains in measuring health-related quality of life (HRQoL) in subjects having cataract surgery. However, the usage of generic instruments has resulted in conflicting evidence. METHODS: In this prospective study, we have evaluated the impact of cataract surgery on subjects' HRQoL measured with a 15-dimension generic instrument, the 15D. The HRQoL of cataract subjects was compared with that of an age- and gender-standardized sample of the general population in Finland. A total of 152 subjects (mean age 74 years, 66% females) with a first-eye cataract surgery completed the 15D questionnaire both before and 12 months after cataract surgery. RESULTS: When compared with the general population, cataract subjects had much lower HRQoL at baseline (mean difference 0.037 (95% CI: 0.020, 0.054), p < 0.001). At 12 months after cataract surgery, the overall utility index improved from the mean of 0.837 to 0.855 (mean difference 0.018 (95% CI: 0.007, 0.029), p = 0.002). Significant improvement was observed on the following five dimensions: seeing, moving, hearing, usual activities and discomfort/symptoms in the 15D questionnaire. CONCLUSION: Our data indicate that at 12 months after first-eye cataract surgery, patients' HRQoL is slightly better than that before surgery. However, patients' postoperative HRQoL may remain lower than that of an age-and gender-standardized control population.

Vision-related Quality of Life Outcomes of Cataract Surgery in Advanced Glaucoma Patients.

PURPOSE: To demonstrate longitudinal postoperative vision-related quality of life and visual acuity changes after cataract surgery in advanced glaucoma patients. MATERIALS AND METHODS: In total, 93 patients who underwent cataract surgeries were collected from June 2010 through June 2013 in Shanghai First People's Hospital, Shanghai Jiao Tong University, and were followed up for at least 3 months. Patients with advanced glaucoma, here defined as near total cupping of the optic nerve with severe visual field loss within 10 degrees of fixation, were enrolled. A standard phacoemulsification technique with the insertion of an intraocular lens was used. No complications occurred intraoperatively or postoperatively. Preoperative and 3-month postoperative vision-related quality of life were assessed in face-to-face interviews. The Chinese-version of the Low Vision Quality of Life Questionnaire (CLVQOL) was used. Wilcoxon signed-rank test was used to compare the differences in the best-corrected visual acuity (BCVA), weighted average LogMAR (WMAR), and CLVQOL scores. A binary logistic regression analysis was conducted to explore the potential factors associated with the change in CLVQOL scores. RESULTS: The overall changes in the CLVQOL composite scores ranged between 4 and 42 (median=19). Statistically significant increases occurred in the composite scores of all of the subscales, the total CLVQOL, the BCVA in the surgery eye, and the WMAR (all P<0.001). Greater increases in the CLVQOL composite scores was associated with superior preoperative WMAR (odds ratio: 9.920, P<0.05), and age below 60 years (odds ratio: 9.905, P<0.05). CONCLUSIONS: Cataract surgery should be recommended for advanced glaucoma patients with stable intraocular pressure.

Visual Outcomes After Cataract Surgery: Multifocal Versus Monofocal Intraocular Lenses.

PURPOSE: To evaluate visual outcomes, spectacle independence, and quality of life among nonastigmatic and astigmatic patients who received AcrySof IQ ReSTOR toric or nontoric multifocal intraocular lenses (IOLs) (Alcon Laboratories, Fort Worth, TX) compared with those who received commercially available nontoric monofocal IOLs after bilateral cataract removal. METHODS: This randomized, patient- and observer-technician-masked study was conducted at 20 sites in Europe. Patients were randomized to receive monofocal (nontoric only) or multifocal (nontoric or toric, as needed) IOLs. Primary efficacy endpoints included percentage of patients achieving binocular uncorrected distance and near acuity of 0.1 logMAR or better (20/25 Snellen), spectacle independence, and scores on the National Eye Institute Refractive Error and Quality of Life questionnaire domains. Safety endpoints included adverse events and refractive error within 0.5 and 1.0 diopters. RESULTS: In the multifocal group (n = 108) versus the monofocal group (n = 100), significantly more patients achieved uncorrected distance and near acuity of 0.1 logMAR or better (45.7% vs 2.1%; P < .0001) and spectacle independence (73.3% vs 25.3%; P < .0001) at 6 months. The percentage of patients who achieved uncorrected distance visual acuity of 20/40 or better at 6 months was 92% in the multifocal group and 97% in the monofocal group. National Eye Institute Refractive Error and Quality of Life scores were significantly better for dependence on correction in the multifocal group (P < .0001) and for glare in the monofocal group (P = .0157); other domain scores were similar between groups. No significant trends in study device-related adverse events were observed. CONCLUSIONS: Monofocal and multifocal IOLs provided good clinical outcomes. More patients receiving multifocal IOLs attained better uncorrected visual acuity at a range of distances and spectacle independence compared with patients who received monofocal IOLs. Monofocal IOLs were associated with better patient-reported scores for glare compared with multifocal IOLs; however, scores for patient satisfaction were significantly better in the multifocal group.

Vector Analysis, Rotational Stability, and Visual Outcome After Implantation of a New Aspheric Toric IOL.

PURPOSE: To evaluate vector analysis, rotational stability, and refractive and visual outcome of a new toric intraocular lens (IOL) for correction of preexisting corneal astigmatism during routine cataract surgery. METHODS: In this prospective, interventional case series, 30 toric, aspheric Bi-Flex T toric IOLs (Medicontur Medical Engineering Ltd., Inc., Zsámbék, Hungary) were implanted in 20 consecutive patients with topographic corneal astigmatism between 1.50 and 4.00 diopters (D) and evaluated within the first year after implantation. Appropriate IOL-toric alignment was facilitated by combined imaging/eye tracking technology. Postoperative evaluation included refraction and uncorrected and corrected distance visual acuities (UDVA, CDVA). For each visit, photodocumentation in retroillumination was performed to evaluate toric alignment and potential toric IOL rotation. Vector analysis of refractive astigmatism was performed using the Alpins method. RESULTS: At 12 months postoperatively, a reduction of the refractive astigmatism from 1.93±0.90 D (range: 0.50 to 4.00 D) to 0.28±0.61 D (range: 0.00 to 1.50 D) could be found, with patients achieving a mean UDVA of 0.06±0.16 logMAR (range: -0.18 to 0.40 logMAR; Snellen 20/20). Intraoperative to 12-month postoperative comparison of IOL axis alignment showed low levels of rotation (0.2°±2.41°; range: +4° to -5°). Vector analysis showed target induced astigmatism of 0.60 D @180°, surgically induced astigmatism of 0.80 D @177°, correction index of 1.02±0.25, and a difference vector of 0.30 D @82°. CONCLUSIONS: Implantation of the new Bi-Flex T IOL was a safe, stable, and effective method to correct preexisting regular corneal astigmatism during cataract surgery.

Visual Acuity, Quality of Life and Visual Function Outcomes after Cataract Surgery in Bali.

PURPOSE: To assess post-cataract surgery intermediate-term (>6 months) data of visual acuity (VA), surgical complications, refractive outcomes, quality of life (QOL) and visual function (VF) from a non-governmental organization program in Indonesia. METHODS: Retrospective cohort study design. Participants were a selection of patients who underwent cataract surgery by the John Fawcett Foundation between 2006 and 2011, with at least 6 months follow-up. Patients underwent comprehensive ophthalmic examinations. QOL and VF questionnaires were administered. RESULTS: From a total of 1557 invited to attend, 547 patients participated; 99.8% of eyes had presenting VA <6/60. At day 1 postoperatively, 52.1% of patients had a good outcome by World Health Organization criteria (unaided VA ≥ 6/18). Six months or later postoperatively, 85% of eyes had best-corrected VA ≥ 6/18 and 5.6% of eyes had best-corrected VA < 3/60. At final follow-up, mean postoperative spherical equivalent refraction was -2.35 diopters (standard deviation 1.75, n = 542). On a scale of 1-100, median converted values for QOL were 25.0 preoperatively and 74.0 postoperatively, a statistically significant improvement (p < 0.001). Of eyes with VA better than 3/60 on postoperative day 1, 5.7% (95% confidence interval 3.6-7.9%) became blind (VA < 3/60) at the 6-month or later time point. CONCLUSION: Cataract surgery in this population markedly improved QOL, despite a trend towards myopic refractive outcomes. These findings raise questions about biometric methodology, intraocular lens power calculations and refractive targets. Postoperative day 1 VA data may be a reasonable proxy of the intermediate-term rate of non-blind eyes.

Effect of position of near addition in an asymmetric refractive multifocal intraocular lens on quality of vision.

PURPOSE: To evaluate the impact of the position of an asymmetric multifocal near segment on visual quality. SETTING: Cathedral Eye Clinic, Belfast, United Kingdom. DESIGN: Retrospective comparative case series. METHODS: Data from consecutive patients who had bilateral implantation of the Lentis Mplus LS-312 multifocal intraocular lens were divided into 2 groups. One group received inferonasal near-segment placement and the other, superotemporal near-segment placement. A +3.00 diopter (D) reading addition (add) was used in all eyes. The main outcome measures included uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), contrast sensitivity, and quality of vision. Follow-up was 3 months. RESULTS: Patients ranged in age from 43 to 76 years. The inferonasal group comprised 80 eyes (40 patients) and the superotemporal group, 76 eyes (38 patients). The mean 3-month spherical equivalent was -0.11 D ± 0.49 (SD) in the inferonasal group and -0.18 ± 0.46 D in the superotemporal group. The mean postoperative UDVA was 0.14 ± 0.10 logMAR and 0.18 ± 0.15 logMAR, respectively. The mean monocular UNVA was 0.21 ± 0.14 logRAD and 0.24 ± 0.13 logRAD, respectively. No significant differences were observed in the higher-order aberrations, total Strehl ratio (point-spread function), or modulation transfer function between the groups. Dysphotopic symptoms measured with a validated quality-of-vision questionnaire were not significantly different between groups. CONCLUSION: Positioning of the near add did not significantly affect objective or subjective visual function parameters.

Does cognitive impairment influence outcomes from cataract surgery? Results from a 1-year follow-up cohort study.

BACKGROUND/AIMS: To assess the impact of impaired cognition on visual outcomes 1 year following cataract surgery in a cohort of older people. METHODS: Participants aged 75 years or more with bilateral cataract and scheduled for cataract surgery were recruited consecutively. Cognition was assessed using the revised Addenbrooke's cognitive examination (ACE-R). Participants were divided into two groups: normal (ACE-R ≥88) and impaired cognition (ACE-R <88). Visual quality of life (VQOL) and logarithm of minimum angle of resolution visual acuity (VA) were assessed at baseline and 1 year following cataract surgery. RESULTS: Of 112 participants, 48 (43%) had normal cognition and 64 (57%) had impaired cognition. One year following cataract surgery participants in both groups had significant improvements in VQOL and VA. Visual outcomes at 1 year were significantly better in participants with normal cognition than in those with impaired cognition (95% CIs for difference 0.4-7.0 and 0.02-0.1, for VQOL and VA, respectively). Regression analyses correcting for potential confounders showed a relationship between baseline cognition and VA at 1 year (R(2)=0.30, p=0.001) and a possible relationship between baseline cognition and VQOL at 1 year (R(2)=0.41, p=0.01, this became insignificant after removal of outliers). CONCLUSIONS: Patients with impaired cognition benefit from cataract surgery, but not to the same extent as patients with normal cognition.

Impact of personality characteristics on patient satisfaction after multifocal intraocular lens implantation: results from the "happy patient study".

PURPOSE: This prospective multicenter study assessed personality characteristics that may influence patient satisfaction after implantation of multifocal intraocular lenses (MIOLs). METHODS: One hundred eighty-three patients who underwent bilateral implantation of different MIOLs were enrolled. Uncorrected and corrected distance visual acuity for distance and near (ie, UDVA, UNVA, CDVA, and CNVA) were assessed preoperatively and 3 and 6 months after implantation. Before surgery, personality characteristics were evaluated using a questionnaire based on the NEO Personality Inventory Test and the Compulsiveness Inventory Test. At the 3- and 6-month postoperative visits, patients answered a questionnaire concerning overall satisfaction, need for spectacles at different distances, visual function at different distances and lighting conditions, photic phenomena, and ease of performing daily activities. RESULTS: Three months after surgery (n = 163), mean CDVA was 0.03 ± 0.09 logMAR, UDVA was 0.05 ± 0.09 logMAR, and UNVA was 0.04 ± 0.11 logMAR. At the 6-month visit (n = 131), mean CDVA was 0.02 ± 0.07 logMAR, UDVA was 0.06 ± 0.09 logMAR, and UNVA was 0.05 ± 0.01 logMAR. Most patients (82.2%) would opt for an MIOL again, 3.7% would not, and 14.1% were uncertain. Overall satisfaction with the procedure was correlated to low astigmatism, good visual function, low spectacle dependence, and less halos or glare. The personality characteristics of compulsive checking, orderliness, competence, and dutifulness were statistically significantly correlated to subjective disturbance by glare and halos. CONCLUSIONS: Postoperative patient satisfaction after MIOL implantation is correlated to visual performance, spectacle independence, and less photic phenomena. Personality characteristics have an impact on subjective disturbance by photic phenomena and thus are important for patient satisfaction.

Health-related quality of life in children operated for pediatric cataracts.

PURPOSE: To evaluate health-related quality of life (HRQOL) in children who had surgery for pediatric cataracts. METHODS: Twenty-five children were divided into 2 groups according to the age at the time of survey (younger than 6 years in group A and 7 years and older in group B). A questionnaire that had 1 part appraising the child's perception and 3 parts evaluating the functional, social, and surgical apprehensions of parents was given to the participants. The questions in the first part were answered by parents in group A (proxy test) and by children in group B (self test). The correlations between the results and patient characteristics were evaluated statistically. RESULTS: Mean (range) score for the first part was 79.5 (58-97) in group A and 70 (56-86) in group B. Functional, social, and surgical scores were 42.5 (0-80), 45 (5-100), and 63 (12.5-100) in group A and 40 (10-90), 70 (40-85), and 75 (25-100) in group B. Functional, social, or surgical scores were not significantly different between groups. Social apprehensions were significantly higher in parents of patients with preoperative strabismus in group B. Functional, social, surgical apprehensions, and children's thoughts were not correlated significantly with age, sex, family history, laterality, associated nystagmus, aphakia or pseudophakia, postoperative optical rehabilitation, or the need for additional surgery in the groups. CONCLUSIONS: Although pediatric cataracts are known to have a great impact on children's life socially and functionally, there was no significant relationship between patient characteristics and HRQOL. The associated preoperative strabismus causes more social concern in the parents.

Objetivo: Determinar si la mejoría de agudeza visual (AV) en los pacientes con opacificaciónde cápsula posterior del cristalino (OCP) que se acepta tras la capsulotomía, se traduce encambios positivos en la percepción de su calidad de vida.Método: Se evaluaron 130 pacientes con OCP antes y después de la capsulotomía. Ademásde la exploración oftalmológica se recogieron las respuestas del cuestionario EuroQol y seestudió la influencia de factores demográficos en el resultado del test.Resultados: La agudeza visual binocular (AVB) media y las puntuaciones medias de las cincodimensiones del cuestionario EuroQol y de la EVA mejoraron en el conjunto de pacientesde forma estadísticamente significativa tras la capsulotomía. No todas las tareas de la vidadiaria se afectan en el mismo grado por el estado de la AV. Las limitaciones en la dimensiónde actividades cotidianas son las que más disminuyen con el tratamiento. La dimensión enla que más dificultades continúan relatando los pacientes tras la capsulotomía es en la demovilidad.Conclusiones: La deficiencia visual ocasionada por la OCP conlleva dificultades para realizarlas actividades cotidianas. La capsulotomía supone un incremento en la AV y en lafuncionalidad de la mayoría de los pacientes, mejorando la percepción sobre su estado desalud(AU)

Objective: To determine whether visual acuity (VA) improvement in patients with posteriorcapsule opacification (PCO), accepted after the capsulotomy, is followed by positive changesin the perception of their quality of life.Method: A total of 130 patients with PCO were examined before and after capsulotomy. In addition to the ophthalmic examination, the EuroQol questionnaire was completed. We analyzed the influence of demographic characteristics on the outcome of the test. Results: The mean binocular visual acuity (BVA) and the mean scores in the EuroQol dimensionsand EQ-VAS improved significantly after capsulotomy. VA did not have the same effecton dailycommontasks. After treatment, the problems in the usual activities dimension haveseen the largest reduction. Mobility is still the dimension with more problems regardingpatients after capsulotomy.Conclusions: Decreased VA induced by PCO is associated with difficulties performing dailyliving activities. Capsulotomy results in a gain in VA and functional ability of the majorityof patients, improving the perception of their quality of life

Stereopsis in children with unilateral pseudophakia.

AIM: To evaluate stereoacuity and the factors that can influence stereopsis in children with unilateral pseudophakia. METHODS: Charts of 38 patients who were diagnosed as having unilateral cataract and underwent cataract extraction with primary intraocular lens implantation were retrospectively reviewed. Data were collected on gender, age, race, age at presentation and the surgery, cataract types, the presence of strabismus before and after cataract extraction, refractive error and the presence of anisometropia, best corrected visual acuity (VA) of both eyes and stereoacuity. RESULTS: Thirty-eight patients were divided into two groups. Group I had 21 patients whose stereopsis was better than 400 s of arc. Seventeen patients in group II had stereopsis poorer than 400 s of arc. The mean ages at presentation and surgery were 4.9 and 6.3 years in group I and 2.7 and 3.0 in group II, respectively (p = 0.046,0.007). Posterior lenticonus was the most common cataract type in both groups (p = 0.20). Strabismus was more frequently associated with group II. Those who had no strabismus before and after cataract surgery were 66.7% in group I and 47.1% in group II (p = 0.02). Fifty-two per cent of patients in group I had a VA of 20/40 or better, but in group II, only one patient had a VA of 20/40 (p<0.001). With a VA of 20/40 or better as the reference level, the odds of having good stereopsis decreased significantly if VA in the eye with the cataract was less than 20/60 based on the multiple regression logistic analysis (OR 0.03, p = 0.0027). CONCLUSION: Stereopsis was better in children with later manifesting cataracts, in the absence of strabismus and in cases with a good postoperative VA. The postoperative VA was the most important factor affecting the outcome of stereopsis in children with unilateral pseudophakia.

Decision-making in second-eye cataract surgery: can presence of Pulfrich phenomenon help?

PURPOSE: To determine whether testing for the Pulfrich phenomenon (PP) can be used as a tool to assess the need for and optimal timing of second-eye cataract surgery. METHODS: A total of 61 patients with logMAR 0 visual acuity (VA) after cataract surgery in one eye and logMAR 0.2-0.7 VA in the other eye were tested for PP using a computer-generated oscillating target at Baskent University Hospital. Only patients who had no ophthalmologic or systemic problem that could cause PP were included. In all, 15 normal patients with logMAR 0 VA in both eyes served as controls. The main outcome measures were presence and magnitude (measured by neutral density filters) of PP and presence of complaints related to binocular vision. RESULTS: Of the 61 patients, 36 (59%) and none of the controls were PP (+) (P<0.001). A total of 27 (75%) of the PP (+) patients had logMAR 0.7-0.4 VA, and nine (25%) had logMAR 0.3-0.2 VA (P=0.01). In all, 16 patients (all PP (+)) had developed binocular vision-related complaints since cataract surgery. The mean PP magnitude in these cases was significantly greater than the mean for the 20 patients without complaints (1.2+/-0.5 vs0.6+/-0.4 log units, respectively; P<0.001). There was no significant difference between the mean VA in the complaint (+) and complaint (-) subgroups (P=0.213). CONCLUSION: PP testing may detect binocular visual dysfunction after first-eye cataract surgery; thus, it could help assess the need for second-eye cataract surgery on this basis.
