Does the introduction of streamlight decrease refractive surgery operating time?

PURPOSE: The aim of the study was to analyze the time-savings associated with introduction of Streamlight™ (Alcon Laboratories, Fort Worth, TX, USA) transepithelial photorefractive keratectomy (PRK) in surface corneal ablations. METHODS: All refractive surgeries were performed using the Alcon WaveLight® EX500 at the ArtLife Clinic, Gdansk, Poland. The study included patients treated for refractive errors with transepithelial PRK between April 2019 and October 2021, who were matched with patients treated with alcohol-assisted PRK during the same period. Only results for the left eye were analyzed. RESULTS: One-hundred-five patients underwent transepithelial PRK (age 33.42 ± 8.67 years) and were matched with 105 patients that underwent alcohol-assisted PRK (age 33.05 ± 10.16 years; p = 0.11). The mean preoperative spherical equivalent refraction was - 2.04 ± 2.28 D, and - 1.9 ± 1.71 D for the transepithelial and alcohol-assisted PRK group, respectively (p = 0.20). The total surgery time was non-significantly shorter in transepithelial PRK (349.46 ± 47.83 s) than in alcohol-assisted PRK (354.93 ± 137.63 s; p = 0.7); however, the variance of surgical time was significantly lower in transepithelial PRK (p < 0.001). The laser treatment duration was greater in transepithelial PRK (41.78 ± 17.2 s) than in alcohol-assisted PRK (8.48 ± 6.12 s; p < 0.001), and so was the number of breaks during the laser treatment (0.95 ± 0.63 vs. 0.53 ± 0.88, respectively; p < 0.001). CONCLUSION: The introduction of transepithelial PRK did not bring significant time-associated savings into the refractive surgery suite.

[PUBLICATION TRENDS AND IMPACT OF OPHTHALMOLOGY DEPARTMENTS IN ISRAEL: SUMMARIZING OVER A DECADE OF RESEARCH WITH AN INTERNATIONAL PERSPECTIVE (2011-2021)].

BACKGROUND: A focused bibliographic analysis of Israel's ophthalmology research productivity has never been performed. OBJECTIVES: To assess the research output of Israeli ophthalmology departments between the years 2011-2021 and compare to leading countries in the discipline. METHODS: The PubMed search engine was used to detect all medical articles published between the years 2011 and 2021, with at least one author from an Israeli ophthalmology department. Each entry was reviewed for: year of publication, journal, department, sub-specialty, and study design. Journals were ranked according to Scopus Cite Score. Research output and population data of 7 top-ranked countries in ophthalmology (USA, UK, Japan, Germany, Australia, Canada, China) were documented for comparisons. RESULTS: Overall, 1,919 publications were included. Total research output of Israeli ophthalmology departments significantly increased throughout the study period (R2=0.85, P<0.0001). Medical retina publications were the most prevalent (493 articles, 25.6%), and the most commonly utilized design was cohort (536 articles, 28%). Over a third of all articles (669) were published in Q1 ophthalmology journals, and 16% were published in the top-10 journals. Israel was ranked (1/8) and (3/8) in publications per population and physician, respectively, compared to the other assessed countries. CONCLUSIONS: Between 2011-2021, the research productivity of the Israeli ophthalmological community has constantly increased across all sub-specialties and in high-impact journals. Israel's relative contribution to the ophthalmic medical literature is noteworthy internationally.

Factors Predicting the Need for Re-treatment After Laser Refractive Surgery in Patients With Mixed Astigmatism.

PURPOSE: To identify risk factors that increase the likelihood of re-treatment following refractive surgery in patients with mixed astigmatism. METHODS: This was a retrospective study including patients who underwent either laser in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK) between 2000 and 2019 and had mixed astigmatism (spherical error of +0.50 D or greater and spherical equivalent of less than 0.00 diopters [D]). Patients were divided into two groups according to whether they underwent re-treatments during the study period. RESULTS: Overall, 785 eyes (785 patients) were included. In total, 5.2% of the eyes (n = 41) underwent re-treatment. The re-treatment group was more likely to have preoperative high astigmatism (80.5% vs 48.3%, P < .001), moderate to high hyperopia (36.6% vs 22.3%, P = .035), and to have undergone surgery earlier during the study period (P < .001). They were also more likely to have undergone surgery using the Wave-Light EX200 rather than the EX500 laser platform (Alcon Laboratories, Inc) (P < .001), have a treated optical zone of 6 mm rather than 6.5 mm (P < .001 for both), and their maximum ablation depth was greater (P < .001). There was no difference between the re-treatment and control groups regarding procedure type (PRK vs LASIK). Binary logistic regression found preoperative high astigmatism (odds ratio = 3.97, P < .001) and the type of laser platform used (EX200, odds ratio = 7.78, P < .001) as the only independent factors associated with re-treatment. CONCLUSIONS: Re-treatment rates following correction of mixed astigmatism were 5.2% over 20 years. Use of a sixth-generation laser platform significantly reduced the risk of re-treatment. Presence of high astigmatism is a significant risk factor for re-treatment. There was no difference in retreatment risk between PRK and LASIK. [J Refract Surg. 2024;40(2):e73-e78.].

Bowman Layer Marking for Correct Placement of Corneal Allogeneic Intrastromal Ring Segments.

ABSTRACT: Corneal allogeneic intrastromal ring segments (CAIRS) refer to the placement of allogeneic rings and segments in intrastromal channels within the cornea. Currently, a deepithelialized donor cornea is used as the allogeneic source for CAIRS and the cut ring is turned sideways and implanted so that the thickness can be varied by varying the distance between the concentric trephine blades. In addition, to obtain a greater effect, CAIRSs are preferred to be implanted with the Bowman layer (BL) facing the corneal apex and posterior stroma facing limbally. Being flexible tissue, it is, however, important to prevent twisting and to maintain correct orientation. We describe a simple technique of marking the BL with a gentian violet surgical marker to simplify CAIRS insertion. BL marking allows easy visibility of twists and helps identify improper orientation, thus allowing correct insertion of CAIRS.

Hyperopic LASIK and Postoperative Corneal Steepness: Revisiting the 49D Limit.

PURPOSE: To compare best-corrected visual acuity (BCVA) outcomes of hyperopic laser in-situ keratomileusis (LASIK) with a postoperative corneal steepness above versus below 49D. SETTING: Care-Vision Laser Centers, Tel-Aviv, Israel. DESIGN: Retrospective study. METHODS: This study included consecutive patients who underwent hyperopic LASIK between January 2013 and December 2019. Hyperopic patients were divided into two groups based on postoperative corneal steepness with steep corneas defined >49.0D and the control group ≤ 49.0D. Adjustments were performed to account for differences in baseline and intraoperative parameters. RESULTS: Overall, 1,703 eyes of 1,703 patients were included. Mean age was 48.3 ± 10.0 years and 45.3% were male. Preoperatively, the steep group (2.4%, n=41/1703) had steeper mean (44.6D vs 43.1D, p<0.001) and steep (45.1D vs 43.5D, p<0.001) keratometry, worse logMAR BCVA (0.07 vs 0.04, p=0.02) and higher sphere (4.9D vs 2.9D, p<0.001). Intraoperatively, they had a higher spherical treatment (4.6D vs 2.8D, p<0.001). Following hyperopic LASIK, the steep group had worse logMAR BCVA (0.10 vs 0.06, p=0.01). However, after accounting for differences in baseline and spherical treatment, no significant differences were found in postoperative logMAR BCVA (0.06 vs 0.06, p=0.99). The factors that remained associated with worse postoperative BCVA were higher spherical treatment (0.01 logMAR per 1D, p<0.001) and preoperative BCVA (0.60 logMAR per 1.00 logMAR, p<0.001). CONCLUSION: Postoperative corneal steepness greater than 49D is not associated with worse visual outcomes following hyperopic LASIK. However, lower preoperative visual potential and higher spherical treatment applied are associated with worse outcomes. The 49D cut-off should be revisited.

Tomographic Predictors of Ectasia Development After Keratorefractive Surgery.

PURPOSE: The aim of this study was to identify the risk factors for postkeratorefractive surgery ectasia in unsuspicious tomographies and to report a new index coined diameter of peak locations (DPLs). METHODS: All patients who underwent keratorefractive surgery between 2011 and 2018 at Care-Vision Laser Centers, Israel, and later developed ectasia were included. For each ectasia case, 3 matched controls were selected. Demographic and preoperative, intraoperative, and postoperative data were collected. Multivariate analysis was performed to evaluate the interdependence of the variables. RESULTS: The retrospective study included 19 ectasia and 58 control eyes. There were no significant differences between the groups in ablation depth ( P = 0.73), preoperative spherical equivalent ( P = 0.12), percent tissue altered ( P = 0.71), residual stromal bed ( P = 0.73), and Ectasia Risk Score System ( P = 0.60). The anterior and the posterior symmetry index were significantly higher ( P < 0.001), and DPL was significantly tighter in the ectasia group ( P = 0.01). Binary multiple logistic regression found the symmetry index of the posterior cornea and DPL to be better predictors than age, percent tissue altered, Ectasia Risk Score System, residual stromal bed, and ablation depth. CONCLUSIONS: A higher posterior symmetry index and a tighter DPL are predictors of ectasia in patients with otherwise normal tomographies. A tight DPL implies a weak area in the cornea, which is thin and slightly bulging, increasing the risk of this area becoming ectatic.

Factors Predicting Slow Visual Recovery Following Hyperopic LASIK.

PURPOSE: To identify factors predicting slow visual recovery following hyperopic laser in situ keratomileusis (LASIK). METHODS: The study included consecutive patients who underwent hyperopic LASIK between January 2005 and December 2019 at a single medical center. Patients were divided into two groups according to whether they experienced normal recovery of visual acuity (1-week visit) or slow visual recovery (1-month visit). Visual recovery was defined as achieving an efficacy index of 0.9 or greater. Efficacy index was calculated as postoperative uncorrected distance visual acuity / preoperative corrected distance visual acuity. A comparison of baseline and intraoperative parameters was performed. Binary logistic regression was performed to identify potential predictors of slow visual recovery. RESULTS: Overall, 861 eyes of 861 patients were included. Mean age was 48.0 ± 9.5 years and 55.9% were women. Two hundred forty-nine patients (28.9%) experienced slow visual recovery. Younger age (P = .01), a larger preoperative spherical equivalence (P = .002), and greater maximum ablation depth (P = .002) were predictors of slow visual recovery. In binary logistic regression, female gender (P = .036) and greater spherical equivalence (P = .007) remained significant predictors of slow visual recovery. CONCLUSIONS: Female gender and greater preoperative spherical equivalence were associated with slow visual recovery. Patients may be advised accordingly. [J Refract Surg. 2024;40(1):e42-e47.].

Atopic Disease as a Risk Factor for Recurrent Herpetic Keratitis.

Recurrent herpetic keratitis is a leading cause of blindness worldwide. In this population-based cross-sectional study, the medical records of Israeli adolescents and young adults who underwent systematic preconscription evaluation for mandatory military service were reviewed. The prevalence of atopic conjunctival disease was evaluated in cases with and without documented recurrent herpetic keratitis. The association was tested using uni- and multivariant analyses. Overall, 940,892 adolescents and young adults were included. The mean age was 17.57 ± 1.50 years (range 16-20 years), and 40.70% of participants were female. Recurrent herpetic keratitis was documented in 160 cases, with a prevalence of 0.017% in this age group. Compared to the general population, patients with recurrent herpetic keratitis were significantly more likely to be males (p = 0.003) with a concomitant diagnosis of atopic conjunctival disease (p < 0.0001). Patients with atopic conjunctival disease were 10.60-fold more likely to experience recurrent herpetic keratitis (95% confidence interval (CI): 6.76-16.64, p < 0.0001). Upon multivariate analysis, the results remained significant (p < 0.001). Cases of severe atopic conjunctival disease were more prone to recurrent HSV keratitis compared to mild cases (p < 0.001). These findings suggest that the timely appropriate treatment of atopic conjunctival disease may help reduce the frequency and severity of recurrent HSV keratitis and its complications.

Systemic antibiotic treatment for meibomian gland dysfunction-A systematic review and meta-analysis.

PURPOSE: To review the efficacy and safety of oral doxycycline antibiotics versus macrolides in the treatment of meibomian gland dysfunction (MGD). DESIGN: Systematic review and meta-analysis. METHODS: We performed a systematic search of electronic databases for all peer-reviewed published studies which included clinical outcomes of oral antibiotic MGD treatment. Individual study data were extracted and evaluated in a weighted pooled analysis, including total sign and symptom scores, meibomian gland secretion score, tear break-up time (TBUT), fluorescein staining score and rate of complications. RESULTS: Two thousand nine hundred and thirty-three studies were found, of which 54 were eligible for the systematic review, and six prospective studies were ultimately included for analysis, reporting on 563 cases from three countries. Age of affected patients ranged between 12 and 90 years. Overall, both treatment methods induced improvement in MGD signs and symptoms. In pooled analysis, macrolides were significantly superior in the total signs score (pooled standardized mean difference (SMD) -0.51, 95% confidence interval (CI): -0.99 to -0.03), meibomian gland secretion score (pooled SMD -0.25, 95%CI: [-0.48, -0.03]), TBUT (SMD -0.31, 95%CI: [-0.50, -0.13]) and fluorescein staining score (SMD -1.01, 95%CI: [-1.72, -0.29]). Moreover, while no severe complications were reported for both treatments, the macrolide group exhibited significantly less adverse events (pooled odds ratio 0.24 with a 95% CI of 0.16 to 0.34). CONCLUSIONS: Both macrolides and tetracyclines are effective treatments for MGD. In this study, macrolides exhibited better efficacy and safety profile compared to tetracyclines.

Peripapillary retinal nerve fiber layer thickness as a diagnostic tool for pseudophakic cystoid macular edema.

PURPOSE: To investigate the effects of pseudophakic cystoid macular edema (PCME) on retinal nerve fiber layer (RNFL) thickness before and after treatment using optical coherence tomography (OCT). METHODS: A retrospective, observational study of consecutive patients diagnosed with PCME after cataract surgery. Patients underwent macular and RNFL OCT imaging at time of diagnosis and during follow up. OCT was performed for both the study eye and the contralateral healthy eye which served as control. All patients were followed for a period of at least 6 months. RESULTS: Overall, 40 eyes of 40 patients with a mean age of 71.1 ± 8.1 years of which 45% (n = 18) were of male gender were included in this study. At presentation, the central thickness in the PCME eye was significantly higher than in the contralateral eye (515.7 ± 127.9µm versus 238.1 ± 41.8µm, p < 0.001). Similarly, all macular measurements were significantly higher in the PCME eye compared to the contralateral eye (p < 0.001 for all). In terms of RNFL measurements, the PCME eyes had greater global (p < 0.001), superonasal (p = 0.001) and superotemporal (p = 0.005) thickness values. PCME eyes demonstrated a significant decrease in thickness for all macular and RNFL parameters following resolution of CME (p < 0.05 for all). CONCLUSIONS: PCME patients presents with greater global, superotemporal and superonasal RNFL thickness in comparison to the other healthy eye. After resolution of PCME, there is significant thinning of RNFL. Peripapillary RNFL thickness may serve as an additional parameter for diagnosis and follow-up of PCME.

Photorefractive keratectomy in flat, normal, and steep corneas.

PURPOSE: To compare photorefractive keratectomy (PRK) outcomes in patients with different corneal steepness. SETTING: Care-Vision Laser Center, Tel-Aviv, Israel. DESIGN: Retrospective comparative chart review. METHODS: Patients included in this study underwent wavefront optimized myopic PRK between January 2013 and December 2019. Patients were divided into 3 groups based on the steepness of the cornea (steep keratometry) (flat: <42 diopters [D], normal: 42 to 46 D and steep: >46 D). One to one matching was performed to verify that baseline parameters (age, preoperative visual acuity and refractive error) were similar between groups. Primary outcome measures were: postoperative corrected/uncorrected distance visual acuity (CDVA/UDVA), efficacy index (postoperative UDVA/preoperative CDVA), safety index (postoperative CDVA/preoperative CDVA), spherical equivalence (SEQ) and cylinder. RESULTS: After matching, 650 eyes were included in each group, which were similar in baseline parameters. There were no significant postoperative differences between flat, normal, and steep corneas in terms of safety index (1.02 vs 1.03 vs 1.03, P = .28), efficacy index (1.01 vs 1.01 vs 1.02, P = .57), logMAR CDVA (0.01 vs 0.02 vs 0.01, P = .76), logMAR UDVA (0.02 vs 0.03 vs 0.02, P = .68), %SEQ within 0.50 D (73.9% vs 74.2% vs 74.6%, P = .95) or 1.00 D of target (91.9% vs 92.5% vs 92.2%, P = .92), %cylinder within 0.50 D (82.8% vs 82.2% vs 81.4%, P = .81) or 1.00 D of target (96.9% vs 97.1% vs 97.2%, P = .95). CONCLUSIONS: No significant differences were found between flat, normal and steep corneas following wavefront-optimized myopic PRK. Thus, this procedure may be safely and effectively performed in both flat and steep corneas.

Angle Kappa Influence on Multifocal IOL Outcomes.

PURPOSE: To characterize angle kappa and study the relationship between preoperative angle kappa and postoperative refractive accuracy, visual outcomes, and patient satisfaction in a large population of eyes with multifocal intraocular lens (MIOL) implantation. METHODS: A comprehensive electronic medical record chart review of 26,470 consecutive eyes that underwent immediate sequential bilateral cataract or refractive lens exchange with MIOLs was conducted. The primary outcome measures were postoperative monocular uncorrected distance visual acuity (UDVA), manifest refraction sphere and cylinder, spherical equivalent (SEQ), defocus equivalent (DEQ), subjective quality of vision at near, intermediate, and distance, and the likelihood of recommending the procedure. Relationships between preoperative angle kappa and postoperative outcomes were assessed with Pearson correlations. RESULTS: Angle kappa followed a right-skewed normal distribution (R2 = 0.99) with a mean ± standard deviation of 0.64 ± 0.27 mm. No clinically meaningful relationship was found between preoperative angle kappa and postoperative sphere, cylinder, SEQ, and DEQ, all with R2 ⩽ 0.0005. Similarly, there was no clinically meaningful relationship between preoperative angle kappa and postoperative UDVA (R2 = 0.001), postoperative satisfaction for near, intermediate, and distance vision (all R2 ⩽ 0.0023), or for recommending the MIOL surgery to friends and relatives (R2 = 0.0000). CONCLUSIONS: Preoperative angle kappa does not have a predictive clinical impact on postoperative MIOL visual outcomes, refractive accuracy, or subjective patient satisfaction. Angle kappa as a single variable cannot be used to determine MIOL candidacy. [J Refract Surg. 2023;39(12):840-849.].

Factors associated with changes in posterior corneal surface following laser-assisted in situ keratomileusis.

PURPOSE: To identify factors associated with changes in the posterior corneal curvature following laser-assisted in situ keratomileusis (LASIK). METHODS: This retrospective study included myopic astigmatic eyes that underwent LASIK between January and December 2013 at Care-Vision Laser Center, Tel-Aviv, Israel. The average posterior keratometry was measured with the Sirius device at a radius of 3 mm from the center. The correlations between the surgically induced change in average posterior keratometry and preoperative parameters such as preoperative sphere, cylinder, spherical equivalent, central corneal thickness (CCT), refraction, Baiocchi Calossi Versaci (BCV) index, ablation depth, percent of tissue altered (PTA), and residual stromal bed (RSB) are reported. RESULTS: A total of 115 eyes with a mean age of 32.5 ± 8.3 years (range 22-56 years) were included. Central corneal thickness (p < 0.005), preoperative sphere (p < 0.001), spherical equivalent (p < 0.005), and preoperative posterior inferior/superior ratio (p < 0.05) were all significantly correlated with the percentage of change in the mean posterior K. According to ranked stepwise multiple regression analysis, 22% of the variance of change in posterior K could be explained by the examined factors. The factors that remained significant were the percentage of change in posterior inferior/superior ratio, preoperative subjective sphere, and preoperative mean posterior K (for all, p < 0.001). CONCLUSIONS: The percentage of change in posterior inferior/superior ratio, subjective sphere, and preoperative mean posterior K are all correlated with change in the mean posterior K after LASIK. Understanding of the variables that can influence posterior corneal changes following refractive surgery may play a role in the prevention of iatrogenic keratectasia.

Comparison of long-term outcomes of simultaneous accelerated corneal cross-linking combined with intracorneal ring segment or topography-guided photorefractive keratectomy.

PURPOSE: To compare long term outcomes of simultaneous accelerated corneal cross-linking (CXL) with intrastromal corneal ring segments (CXL-ICRS) to simultaneous accelerated CXL with topography-guided photorefractive keratectomy (CXL-TG-PRK) in progressive keratoconus. SETTING: The Kensington Eye Institute and Bochner Eye Institute, Toronto, Canada. DESIGN: Prospective non-randomized interventional study. METHODS: The change in visual and topographical outcomes of CXL-ICRS and CXL-TG PRK 4-5 years after surgery were compared using linear regression models adjusting for preoperative corrected distance visual acuity (CDVA) and maximum keratometry (Kmax). RESULTS: Fifty-seven eyes of 43 subjects with progressive keratoconus that underwent simultaneous accelerated (9 mW/cm2, 10 minutes) CXL-ICRS (n=32) and CXL-TG-PRK (n=25) were included. Mean follow-up duration was 51.28 (9.58) and 54.57 (5.81) months for the CXL-ICRS and CXL-TG-PRK groups, respectively. Initial mean Kmax was higher in the CXL-ICRS compared to CXL-TG-PRK group (60.68±6.81D VS 57.15±4.19D, p=0.02). At last follow-up, change (improvement) in logMAR uncorrected distance visual acuity (UDVA) compared to pre operatively was significant with CXL-ICRS (-0.31±0.27, p<0.001 which is equivalent to approximately 3 lines) and not significant with CXL-TG-PRK (-0.06±0.42, p=0.43). The logMAR CDVA improved significantly with CXL-ICRS (-0.22±0.20, p<0.001) but not with CXL-TG-PRK (-0.05±0.22, p=0.25). Adjusting for baseline Kmax and CDVA, the improvement in UDVA was significantly greater with CXL-ICRS than with CXL-TG-PRK (-0.27 [95% CI, 0.06 to 0.47, P = 0.01]). Improvement in CDVA was not significantly different. CONCLUSION: In this cohort of progressive keratoconus with long term follow up UDVA showed more improvement with accelerated CXL-ICRS than with CXL-TG-PRK.

The Efficacy and Safety of Standard versus Soft Topical Steroids after Cataract Surgery: A Systematic Review and Meta-analysis.

TOPIC: Review of the efficacy and safety of standard versus soft topical steroid application after cataract surgery. CLINICAL RELEVANCE: The control of postoperative inflammation is the mainstay of treatment after cataract surgery. However, no consensus exists regarding the postoperative steroid of choice. Basing the choice of topical postoperative steroidal treatment on high-quality data regarding both risks and benefits of various drugs would be advantageous for both patients and clinicians. METHODS: A systematic search of the PubMed, Scopus, and Embase electronic databases for all peer-reviewed published randomized control trials that included clinical outcomes of topical steroidal treatment after uneventful cataract surgery was performed. Individual study data were extracted and evaluated in a weighted pooled analysis including grading of total anterior chamber (AC) inflammation, AC cells, AC flare, postoperative visual acuity (VA), intraocular pressure (IOP), and rate of adverse events (AEs). RESULTS: Overall, 508 studies were found, of which 7 were eligible for the systematic review and ultimately were included for analysis, reporting on 593 patients from 5 countries. Age of included patients, when available, ranged between 3.7 and 73.4 years. Follow-up data were available for analysis at 1, 7, and 28 days after surgery. Except for a significantly lower grade of AC flare in the standard steroid group at day 7 (standardized mean difference, 0.26; 95% confidence interval, 0.05-0.47; I2 = 0%), inflammatory activity measurements displayed insignificant differences at every other follow-up (days 1 and 28 after surgery). Pooled analysis of IOP at each follow-up demonstrated a higher IOP at the 7-day visit in the standard steroid group, whereas IOP at other time points was comparable among the groups. Qualitative analysis of ocular AEs showed similarities among the groups. DISCUSSION: The findings of this study suggest that for the average patient, both groups produce a comparable effect on both AC inflammation and postoperative IOP and VA.

Factors Predicting Loss of Best-Corrected Visual Acuity After Hyperopic Laser-Assisted In Situ Keratomileusis.

PURPOSE: The aim of this study was to identify risk factors for the loss of corrected distance visual acuity (CDVA) after uncomplicated hyperopic laser-assisted in situ keratomileusis (LASIK). METHODS: A retrospective study including hyperopic patients who underwent microkeratome-assisted LASIK between January 2000 and December 2019 at Care-Vision Laser Centers, Tel-Aviv, Israel. Loss of CDVA was defined as ≥ 2 lines (0.20 logarithm of the minimum angle of resolution [logMAR] increase). Excluded were patients who had loss of CDVA because of intraoperative or postoperative complications or developed cataract at their final visit. RESULTS: Overall, 1998 eyes of 1998 patients were included in the study, of which 35 eyes (1.75%) had CDVA loss at final follow-up (mean 387 days). The vision-loss group had a significantly greater spherical treatment (3.4 vs. 2.8 D, P = 0.02), ablation depth (69.4 vs. 53.8 µm, P = 0.01), a higher proportion of treatments with a smaller optic zone (6.0 mm) (31.4% vs. 13.4%, P = 0.002), treatment with the EX200 (Alcon) excimer rather than the EX500 (Alcon) (74.3% vs. 39.0%, P < 0.001), and treatment with the Moria M2-90 microkeratome rather than the Moria Sub-Bowman's keratomileusis (SBK) microkeratome (65.7% vs. 29.6%, P < 0.001). In multivariate binary logistic regression, factors that remained significant predictors of CDVA loss were a greater spherical treatment (per 1 D treatment, odds ratio = 1.42, 95% CI, 1.11-1.81, P = 0.004) and the use of the Moria M2-90 microkeratome (odds ratio = 4.66, 95% CI, 2.30-9.45, P < 0.001). CONCLUSIONS: In patients undergoing uncomplicated hyperopic LASIK, a greater spherical hyperopic treatment is associated with a higher risk for vision loss. Transition to a newer microkeratome model significantly reduced vision loss rate.

Is there room for prompt routine ophthalmic examination in neonates with congenital cytomegalovirus (CMV) infection during the neonatal period?

PURPOSE: To establish the clinical necessity of routine targeted ophthalmic examination of newborns with congenital cytomegalovirus (CMV) infection during the neonatal period. METHODS: This retrospective study included consecutive neonates that were referred for ophthalmological screening within the context of a proven congenital CMV infection. The presence of CMV-related ocular and systemic findings was determined. RESULTS: Among the 91 patients included in this study, 72 (79.12%) were symptomatic with one or more of the following manifestations: abnormal brain ultrasound (42; 46.15%), small for gestational age (29; 31.87%), microcephaly (23; 25.27%), thrombocytopenia (14; 15.38%), sensory neural hearing loss (13; 14.29%), neutropenia (12; 13.19%), anemia (4; 4.4%), skin lesions (4; 4.4%), hepatomegaly (3; 3.3%), splenomegaly (3; 3.3%), direct hyperbilirubinemia (2; 2.2%). Not one single neonate in this cohort had any of the ocular findings surveyed. CONCLUSION: The presence of ophthalmological findings among neonates with congenital CMV infection during the neonatal period is infrequent, suggesting that routine ophthalmological screening may be safely deferred for the post-neonatal period.

Toric Trifocal Intraocular Lens for Refractive Lens Exchange: A Multi-center, Multi-surgeon Large Cohort Study.

PURPOSE: To assess the outcomes of a novel toric trifocal intraocular lens (IOL) for refractive lens exchange (RLE) in a large series of eyes with corneal astigmatism. METHODS: Consecutive eyes that underwent RLE with the PanOptix Toric IOL (Alcon Laboratories, Inc) were included. Outcomes measures included postoperative distance (UDVA), 60 cm intermediate (UIVA), and 40 cm near (UNVA) uncorrected visual acuity, manifest refraction, spherical and defocus equivalent, efficacy and safety indices, and vector analyses of refractive and toric IOL accuracy. RESULTS: A total of 4,933 eyes had a median follow-up of 3 months. UDVA of 20/20 and 20/40 was obtained in 65% and 99% of eyes monocularly and 87% and 100% binocularly, respectively. UIVA at 60 cm of 20/25 and 20/40 was achieved in 70% and 99% of eyes monocularly and in 77% and 100% binocularly, respectively. UNVA at 40 cm of 20/25 and 20/40 was achieved in 85% and 96% of eyes monocularly and in 95% and 100% binocularly, respectively. A total of 67%, 89%, 97%, and 99% of eyes had a SEQ within 0.25, 0.50, 0.75, and 1.00 diopter (D) of intended target (R2 = 0.99). Postoperative refractive astigmatism of 0.50, 0.75, and 1.00 D or less was achieved in 86%, 95%, and 98% of eyes. The vector analysis correction index and index of success were 1.04 ± 0.35 and 0.41 ± 0.31 for toric IOL accuracy and 1.00 ± 0.46 and 0.36 ± 0.55 for refractive accuracy, respectively. The 3- and 12-month post-RLE excimer laser enhancement rates were 1.1% (95% CI: 0.8% to 1.4%) and 7.6% (95% CI: 6.9% to 8.3%), respectively. CONCLUSIONS: The PanOptix Toric IOL performed well for a wide range of axial lengths and corneal astigmatism in eyes that had RLE. Most patients achieved effective uncorrected binocular near, intermediate, and distance vision for daily functioning. [J Refract Surg. 2023;39(5):302-310.].
