RESUMO

PURPOSE: To review the published literature evaluating the visual and refractive outcomes and rotational stability of eyes implanted with toric monofocal intraocular lenses (IOLs) for the correction of keratometric astigmatism during cataract surgery and to compare those outcomes with outcomes of eyes implanted with nontoric monofocal IOLs and other astigmatism management methods performed during cataract surgery. This assessment was restricted to the toric IOLs available in the United States. METHODS: A literature search of English-language publications in the PubMed database was last conducted in July 2022. The search identified 906 potentially relevant citations, and after review of the abstracts, 63 were selected for full-text review. Twenty-one studies ultimately were determined to be relevant to the assessment criteria and were selected for inclusion. The panel methodologist assigned each a level of evidence rating; 12 studies were rated level I and 9 studies were rated level II. RESULTS: Eyes implanted with toric IOLs showed excellent postoperative uncorrected distance visual acuity (UCDVA), reduction of postoperative refractive astigmatism, and good rotational stability. Uncorrected distance visual acuity was better and postoperative cylinder was lower with toric IOLs, regardless of manufacturer, when compared with nontoric monofocal IOLs. Correcting pre-existing astigmatism with toric IOLs was more effective and predictable than using corneal relaxing incisions (CRIs), especially in the presence of higher magnitudes of astigmatism. CONCLUSIONS: Toric monofocal IOLs are effective in neutralizing pre-existing corneal astigmatism at the time of cataract surgery and result in better UCDVA and significant reductions in postoperative refractive astigmatism compared with nontoric monofocal IOLs. Toric IOLs result in better astigmatic correction than CRIs, particularly at high magnitudes of astigmatism.

RESUMO

BACKGROUND: Incorporation of the rapid advances in ophthalmologic surgical and diagnostic techniques inherent in the field poses a challenge to residency training programs. This study investigates exposure to new technologies during residency and perception of its impact on practice patterns. METHODS: Ophthalmology residents at various training levels and practicing ophthalmologists who had completed their training were invited to participate in a survey study assessing exposure to various technologies in residency and in practice. Data collection occurred from December 2022 to June 2023. Descriptive statistics were performed. RESULTS: The study received 132 unique responses, including 63 ophthalmology residents and 69 practicing ophthalmologists. 65.2% (n = 45) of practicing ophthalmologists and 47.6% (n = 30) of current residents reported discussion/training on newly developed products on the market (e.g. premium IOLS, MIGS), was "minimally discussed but not emphasized" or "not discussed at all" in residency. 55.1% (n = 38) of practicing ophthalmologists reported that exposure to new technologies during residency did influence types of technologies employed during practice. The majority resident physicians reported enjoying being trained on newer technology and feeling more prepared for future changes in the field (95.2%, n = 60) and felt that having industry partnerships in residency enhances education and training (90.5%, n = 57). CONCLUSIONS: Considering how to maximize exposure to newer technologies/devices during residency training is important, and may contribute to training more confident, adaptable surgeons, who are more likely to critically consider new technologies and adopt promising ones into their future clinical practice.

RESUMO

PURPOSE: To evaluate outcomes and the incidence of adverse events (AEs) in patients who underwent bilateral same-day refractive lens exchange (RLE). DESIGN: Retrospective case series. PARTICIPANTS: Patients of a private intraocular surgery provider in the United Kingdom who underwent RLE in both eyes on the same day with treatment dates between March 2018 and December 2021. METHODS: Clinical outcomes and AEs were collected for a continuous cohort of patients undergoing bilateral same-day RLE (in the absence of visually significant cataracts) or had mild cataracts (corrected visual acuity ≥ 20/40). One-month clinical outcomes were analyzed. MAIN OUTCOME MEASURES: Refractive outcomes and visual acuity, intraoperative and postoperative AEs, and secondary surgical interventions recorded within the first month after surgery. RESULTS: A total of 17 330 patients (34 660 eyes) were included in the analysis. Of these, 28 827 eyes received a multifocal intraocular lens (IOL), and 5833 eyes had a monofocal IOL. The percentage of eyes within ±0.50 diopters (D) of intended refraction was 85.5% and 86.2% for monofocal and multifocal IOL eyes, respectively. There was a total of 55 intraoperative AEs recorded in 55 eyes of 54 patients (per-eye incidence: 0.159%). Posterior capsule tear was the most common intraoperative event occurring in 37 eyes (0.107%). The number of AEs recorded within the first postoperative month was 267, occurring in 263 eyes of 177 patients (per-eye incidence: 0.759%). These included cystoid macular edema (CME) (172 eyes; 0.496%), significant corneal edema (28 eyes; 0.081%), persistent inflammation (27 eyes; 0.078%), significantly raised intraocular pressure (27 eyes; 0.078%), toxic anterior segment syndrome (8 eyes; 0.023%), wound leak (3 eyes; 0.009%), retinal detachment (1 eye; 0.003%), and retinal tear (1 eye; 0.003%). There were 56 secondary surgical interventions recorded within the first month of surgery, occurring in 54 eyes of 47 patients (per-eye incidence: 0.156%). The most common secondary intervention was the rotation of a misaligned toric IOL (24 eyes; 0.069%). CONCLUSIONS: Elective same-day bilateral RLE had a low incidence of serious AEs, and high refractive predictability.

RESUMO

OBJECTIVE: To evaluate current best practices for postoperative photorefractive keratectomy (PRK) pain control. METHODS: Literature searches in the PubMed database were last conducted in October 2021 and were restricted to publications in English. This search identified 219 citations, of which 84 were reviewed in full text for their relevance to the scope of this assessment. Fifty-one articles met the criteria for inclusion; 16 studies were rated level I, 33 studies were rated level II, and 2 studies were rated level III. RESULTS: Systemic opioid and nonsteroidal anti-inflammatory drugs (NSAIDs); topical NSAIDs; postoperative cold patches; bandage soft contact lenses (BCLs), notably senofilcon A contact lenses; and topical anesthetics were demonstrated to offer significantly better pain control than comparison treatments. Some other commonly reported pain mitigation interventions such as systemic gabapentinoids, chilled intraoperative balanced salt solution (BSS) irrigation, cycloplegia, and specific surface ablation technique strategies offered limited improvement in pain control over control treatments. CONCLUSIONS: Systemic NSAIDs and opioid medications, topical NSAIDs, cold patches, BCLs, and topical anesthetics have been shown to provide improved pain control over alternative strategies and allow PRK-associated pain to be more tolerable for patients.

RESUMO

PURPOSE: To evaluate refractive outcomes, safety, and cost-effectiveness of femtosecond laser-assisted cataract surgery (FLACS) compared with phacoemulsification cataract surgery (PCS). METHODS: A PubMed search of FLACS was conducted in August 2020. A total of 727 abstracts were reviewed and 33 were selected for full-text review. Twelve articles met inclusion criteria and were included in this assessment. The panel methodologist assigned a level of evidence rating of I to all 12 studies. RESULTS: No significant differences were found in mean uncorrected distance visual acuity, best-corrected distance visual acuity, or the percentage of eyes within ± 0.5 and ± 1 diopter of intended refractive target between FLACS and PCS. Intraoperative and postoperative complication rates were similar between the 2 groups, and most studies showed no difference in endothelial cell loss between FLACS and PCS at various time points between 1 and 6 months. In large randomized controlled studies in the United Kingdom and France, FLACS was less cost-effective than PCS. CONCLUSIONS: Both FLACS and PCS have similar excellent safety and refractive outcomes. At this time, one technique is not superior to the other, but economic analyses performed in some populations have shown that FLACS is less cost-effective.

RESUMO

BACKGROUND: Studies suggest diurnal patterns of occurrence of some eye conditions. Leveraging new information sources such as web-based search data to learn more about such patterns could improve the understanding of patients' eye-related conditions and well-being, better inform timing of clinical and remote eye care, and improve precision when targeting web-based public health campaigns toward underserved populations. OBJECTIVE: To investigate our hypothesis that the public is likely to consistently search about different ophthalmologic conditions at different hours of the day or days of week, we conducted an observational study using search data for terms related to ophthalmologic conditions such as conjunctivitis. We assessed whether search volumes reflected diurnal or day-of-week patterns and if those patterns were distinct from each other. METHODS: We designed a study to analyze and compare hourly search data for eye-related and control search terms, using time series regression models with trend and periodicity terms to remove outliers and then estimate diurnal effects. We planned a Google Trends setting, extracting data from 10 US states for the entire year of 2018. The exposure was internet search, and the participants were populations who searched through Google's search engine using our chosen study terms. Our main outcome measures included cyclical hourly and day-of-week web-based search patterns. For statistical analyses, we considered P<.001 to be statistically significant. RESULTS: Distinct diurnal (P<.001 for all search terms) and day-of-week search patterns for eye-related terms were observed but with differing peak time periods and cyclic strengths. Some diurnal patterns represented those reported from prior clinical studies. Of the eye-related terms, "pink eye" showed the largest diurnal amplitude-to-mean ratios. Stronger signal was restricted to and peaked in mornings, and amplitude was higher on weekdays. By contrast, "dry eyes" had a higher amplitude diurnal pattern on weekends, with stronger signal occurring over a broader evening-to-morning period and peaking in early morning. CONCLUSIONS: The frequency of web-based searches for various eye conditions can show cyclic patterns according to time of the day or week. Further studies to understand the reasons for these variations may help supplement the current clinical understanding of ophthalmologic symptom presentation and improve the timeliness of patient messaging and care interventions.

RESUMO

PURPOSE: To examine factors contributing to completion of a patient-reported outcome (PRO) measure in patients undergoing laser vision correction. DESIGN: Retrospective, population-based study. PARTICIPANTS: All patients who underwent primary laser vision correction with a target of plano from July 1, 2014, to June 30, 2016, at a large refractive surgery center. METHODS: Patients were asked to complete a PRO measure at the time of their preoperative and months 1 and 3 postoperative visits. Characteristics between patients who attended and did not attend the follow-up visits and completed and did not complete the PRO measure were compared. A logistic regression was performed to identify factors associated with likelihood of follow-up and completion of PRO measure. An inverse probability censoring weighted model was created to account for selective loss to follow-up and used to adjust the PRO satisfaction measure. MAIN OUTCOME MEASURE: Completion of the PRO measure at 1 and 3 months. RESULTS: A total of 37 043 patients were identified. Of these, 20 501 completed a 1-month postoperative PRO measure and 10 474 completed a 3-month postoperative PRO measure. Patients completing a PRO measure were more likely to be older, be female, have had photorefractive keratectomy (PRK), have completed a preoperative PRO measure, and have had a preoperative hyperopic correction (P < 0.001 for all comparisons). For every line of postoperative uncorrected acuity worse than 20/16, the odds ratio of completing a PRO measure was 1.33 (95% confidence interval [CI], 1.30-1.36, P < 0.001) at 1 month and 1.29 (95% CI, 1.26-1.33, P < 0.001) at 3 months. At 1 month, there was no difference between the raw and model-adjusted rates of satisfaction with vision, but at 3 months the adjusted rate was significantly higher than the raw rate. CONCLUSIONS: Patients with worse objective visual outcomes were more likely to complete PRO measures in this population-based study. In a setting with loss to follow-up, PRO measures require methods to address missing data for correct interpretation.

RESUMO

PURPOSE: To review the literature to evaluate the outcomes of intraocular lens (IOL) power calculation in eyes with a history of myopic LASIK or photorefractive keratectomy (PRK). METHODS: Literature searches were conducted in the PubMed database in January 2020. Separate searches relevant to cataract surgery outcomes and corneal refractive surgery returned 1169 and 162 relevant citations, respectively, and the full text of 24 was reviewed. Eleven studies met the inclusion criteria for this assessment; all were assigned a level III rating of evidence by the panel methodologist. RESULTS: When automated keratometry was used with a theoretical formula designed for eyes without previous laser vision correction, the mean prediction error (MPE) was universally positive (hyperopic), the mean absolute errors (MAEs) and median absolute errors (MedAEs) were relatively high (0.72-1.9 diopters [D] and 0.65-1.73 D, respectively), and a low (8%-40%) proportion of eyes were within 0.5 D of target spherical equivalent (SE). Formulas developed specifically for this population requiring both prerefractive surgery keratometry and manifest refraction (i.e., clinical history, corneal bypass, and Feiz-Mannis) produced a proportion of eyes within 0.5 D of target SE between 26% and 44%. Formulas requiring only preoperative keratometry or no history at all had lower MAEs (0.42-0.94 D) and MedAEs (0.30-0.81 D) and higher (30%-68%) proportions within 0.5 D of target SE. Strategies that averaged several methods yielded the lowest reported MedAEs (0.31-0.35 D) and highest (66%-68%) proportions within 0.5 D of target SE. Even after using the best-known methods, refractive outcomes were less accurate in eyes that had previous excimer laser surgery for myopia compared with those that did not have it. CONCLUSIONS: Calculation methods requiring both prerefractive surgery keratometry and manifest refraction are no longer considered the gold standard. Refractive outcomes of cataract surgery in eyes that had previous excimer laser surgery are less accurate than in eyes that did not. Patients should be advised of this refractive limitation when considering cataract surgery in the setting of previous corneal refractive surgery. Conclusions are limited by the small sample sizes and retrospective nature of nearly all existing literature in this domain.

RESUMO

PURPOSE: To review the published literature assessing the efficacy and safety of presbyopia-correcting intraocular lenses (IOLs) for the treatment of presbyopia after cataract removal. METHODS: Literature searches were undertaken in January 2018 and September 2020 in the PubMed, Medline, and Cochrane Library databases. This yielded 761 articles, of which 34 met the criteria for inclusion in this assessment and were assigned a level of evidence rating by the panel methodologist. Thirteen studies were rated level I and 21 studies were rated level II. RESULTS: Presbyopia-correcting lenses were effective at improving distance and near visual acuity after cataract surgery. Near acuity at different focal lengths was related directly to the effective add power of multifocal and extended depth-of-focus (EDOF) IOLs. Most multifocal and EDOF lenses that were compared with a control monofocal lens demonstrated that patient-reported spectacle independence was superior to the monofocal lens. All patients who had multifocal and EDOF lenses implanted showed decreased contrast sensitivity and reported more visual phenomena as compared with control participants who received monofocal lenses. CONCLUSIONS: Presbyopia-correcting lenses improve uncorrected near and distance visual acuity and decrease spectacle dependence after cataract surgery. Mesopic contrast sensitivity is decreased compared with monofocal lenses, and patient-reported visual phenomena are more likely in patients receiving multifocal or EDOF lenses.

RESUMO

PURPOSE OF REVIEW: Given the impact that society as a whole, and medicine specifically, has experienced as a result of the COVID-19 pandemic, an examination of clinical care changes enacted in the field of ophthalmology is of interest to the specialty. RECENT FINDINGS: In order to adapt to the reality of the COVID-19 pandemic, measures, such as broadening telehealth capabilities, adopting universal masking, careful sanitation procedures, applying virtual teaching in academic environments, and deferring elective surgeries were put in place. These were aimed at reducing person-to-person spread of SARS-CoV-2. Though best efforts were made at triaging ophthalmic emergencies during these times, unfortunate delays in care were observed in some circumstances. Finally, a prospective study interrogating the risk of spread at slit lamp distances for short periods of time was encouraging, suggesting low risk of transmissibility, though limited by a small case-positive sample size. SUMMARY: Significant changes have been made in the design and delivery of ophthalmic care during the COVID-19 pandemic. Some of these, such as telemedicine, may provide value in a postpandemic world.

RESUMO

PURPOSE: Anecdotal reports of refractive changes in pregnancy are familiar to optometrists and ophthalmologists. Refractive stability during pregnancy has implications in both prescribing of refractive correction and candidacy for refractive surgery. This study aims to examine refractive status in a nationally representative sample of US pregnant women. METHODS: The National Health and Nutrition Examination Survey (NHANES) is a weighted, stratified, cross-sectional survey of the US population conducted every 2 years. During 2005-2006 and 2007-2008, the exam included multiple ophthalmic tests including refraction, keratometry, and lensometry. Female participants aged 20-44 years with available vision examination data were included in the study. Subjects were excluded if best obtainable visual acuity was worse than 20/40 or there was prior history of cataract or refractive surgery. The primary outcome was defined as refractive change stratified by trimester of pregnancy. RESULTS: 301 pregnant women were matched with 301 nonpregnant controls based on age, ethnicity, and education. There was no difference in refractive error between pregnant women and matched nonpregnant controls (all p > 0.99). For the refractive change analysis, a subgroup of 60 pregnant subjects with glasses at presentation was matched to 60 nonpregnant controls. Multivariate regression showed a significant increase in refractive change versus prior to glasses prescription by trimester of pregnancy (p = 0.02), though this change was not in a specific direction (i.e., no significant shift toward either myopia or hyperopia). CONCLUSIONS: Pregnant women have greater refractive difference from prior spectacle prescription later in pregnancy, but the direction of this change is variable and not significant. This finding may reflect a longer time to last glasses prescription later in pregnancy, given concerns that refractive error fluctuates in pregnancy. Additional longitudinal studies are needed to better characterize the effects of pregnancy on refractive status.

RESUMO

Background: In the United States Armed Forces, telemedicine can bring specialist care into the field, augmenting the capabilities of health care providers in remote, austere environments to nearly the point of injury or illness. The early intervention enabled by telemedical consultation can not only guide crucial temporizing measures to safeguard life, limb, and eyesight, but can also facilitate care in resource limited environments, potentially avoiding need for patient evacuation. In circumstances when a higher level of care is needed, but unavailable or operationally not possible, telemedicine can guide management in the field until transport can be achieved. Methods: In the present case, a young male patient presented to medical company aboard a U.S. Navy aircraft carrier while deployed at sea for evaluation of an acute red eye. Despite initial therapeutic measures, his vision subsequently deteriorated. Uveitis was suspected, but transport off the ship to an eye care specialist was not possible during combat operations. Results: Telemedical consultation with shore-based ophthalmologists guided initial diagnostic and therapeutic efforts, resulting in the presumed diagnosis of syphilitic uveitis. With remote support of ophthalmology and infectious disease specialist care, the patient was treated at sea for this vision-threatening condition. As operational conditions allowed, the patient was later evacuated to definitive care. Conclusions: At follow up after treatment, the patient had an excellent visual outcome, and was promptly returned to duty.

RESUMO

PURPOSE: To describe the factors that influence the measured intraocular pressure (IOP) change and to develop a predictive model after myopic and hyperopic LASIK and photorefractive keratectomy (PRK) in a large population. DESIGN: Retrospective, observational case series. PARTICIPANTS: Patients undergoing primary PRK or LASIK with a refractive target of emmetropia between January 1, 2008, and October 5, 2011. METHODS: The Optical Express database was queried for all subjects. Data were extracted on procedure specifics, preoperative central corneal thickness (CCT), IOP (using noncontact tonometry), manifest refraction, average keratometry, age, gender, and postoperative IOP at 1 week, 1 month, and 3 months. A linear mixed methods model was used for data analysis. MAIN OUTCOME MEASURES: Change in IOP from preoperatively to 1 month postoperatively. RESULTS: A total of 174 666 eyes of 91 204 patients were analyzed. Hyperopic corrections experienced a smaller IOP decrease than myopic corrections for both PRK and LASIK (P<0.0001). Patients who underwent LASIK had a 0.94 mmHg (95% confidence interval [CI], 0.89-0.98) greater IOP decrease than patients who underwent PRK (P<0.0001), reflecting the effect of the lamellar flap. The decrease in IOP was linearly related to preoperative manifest spherical equivalent (MSE) for myopic PRK and LASIK (P<0.0001), weakly correlated with preoperative MSE after hyperopic LASIK, and not related to preoperative MSE after hyperopic PRK. The single greatest predictor of IOP change was preoperative IOP across all corrections. By using the available data, a model was constructed to predict postoperative IOP change at 1 month; this was able to explain 42% of the IOP change after myopic LASIK, 34% of the change after myopic PRK, 25% of the change after hyperopic LASIK, and 16% of the change after hyperopic PRK. CONCLUSIONS: Myopic procedures lower measured IOP more than hyperopic procedures; this decrease was proportional to the amount of refractive error corrected. Independent of the refractive correction, the creation of the lamellar LASIK flap decreased measured IOP by 0.94 mmHg. A best-fit model for IOP change was developed that may allow better interpretation of post-laser vision correction IOP values.

RESUMO

Purpose: To examine the effect of preoperative angle kappa on patient-reported outcomes after multifocal lens placement during cataract surgery and determine if it is an effective measure for preoperative patients screening for multifocal lens placement. Setting: Private refractive surgery clinics. Design: Retrospective cohort study. Methods: All patients undergoing bilateral cataract or refractive lens exchange surgery with a target of emmetropia between 2013 and 2017 at Optical Express (Glasgow, UK) with multifocal lens placement for whom preoperative angle kappa measurement and a postoperative month 1 patient-reported outcomes measures were available were included. Results: A total of 1368 patients were identified. Median preoperative angle kappa was 0.41mm with an interquartile range of 0.30mm to 0.53mm. Preoperative angle kappa did not have a significant association with patient-reported satisfaction with vision (correlation coefficient 0.15, 95% confidence interval -0.081 to 0.39, P = 0.20) nor with patient-reported photic phenomena (P > 0.09 for all comparisons). A receiver-operator characteristic analysis did not yield a viable cutoff predictive of patient-reported satisfaction. Conclusion: Angle kappa was not predictive of patient-reported satisfaction in this study. This study did not find evidence that it should be used as a screening test for patients considering multifocal intraocular lens placement.

RESUMO

PURPOSE: To assess the effect of residual sphere on vision and satisfaction in pseudophakic patients. SETTING: Private clinics, United Kingdom. DESIGN: Retrospective case series. METHODS: A multivariate model evaluated the effect of 1-month residual sphere on outcomes of pseudophakic patients. Odds ratios (ORs) were calculated to assess the relative risk of not achieving ≥20/20 monocular uncorrected distance visual acuity (UDVA), ≥20/50 uncorrected near visual acuity (UNVA), and not being satisfied with vision. ORs were assessed for residual sphere -1.00 to +1.00 diopter (D) in quarter-diopter steps, using 0.00 D as a reference. RESULTS: The analysis included 38 828 multifocal and 11 571 monofocal intraocular lenses (IOLs). The residual myopic sphere ≤-0.25 D and hyperopic sphere ≥+0.50 D had a clinically meaningful effect on UDVA. Although monofocal IOLs had an improvement in UNVA with every additional 0.25 D of myopia, the change in ORs with increasing myopia was not significant for multifocal IOLs. The mean improvement in UNVA comparing eyes with 0.00 D and -1.00 D sphere was 0.26 logMAR for monofocal and 0.03 logMAR for multifocal IOLs. Low near-addition IOLs had a slightly higher gain in UNVA with increasing myopia, but the gain was not as substantial as with monofocal IOLs. The effect of ametropia on satisfaction was more pronounced for multifocal IOLs. For every 0.25 D of residual myopia, there was >25% increase in dissatisfied patients. CONCLUSIONS: Although myopia improved UNVA in eyes with monofocal IOL, multifocal IOLs did not benefit from residual myopia. Multifocal IOL patients desiring distance vision should be targeted closest to emmetropia, even if it means targeting slight hyperopia.

RESUMO

Purpose: To report our experience of performing immediate sequential bilateral cataract surgery (ISBCS) in patients with visually significant cataracts and reduced preoperative corrected distance visual acuity (CDVA). Methods: Data of patients who underwent ISBCS for visually significant cataracts and had preoperative CDVA ≤20/32 (≤0.2 logMAR) in each eye were retrospectively reviewed. Refractive and visual outcomes were evaluated for the last available postoperative visit. Intraoperative and serious postoperative adverse events occurring within the first three months of surgery were reviewed. Results: A total of 1335 patients (2670 eyes) were included in the analysis, with a mean age of 71.9 ± 9.5 years. On the last visit, 50.2% and 89.1% of eyes achieved uncorrected distance visual acuity (UDVA) ≥20/20 (0.0 logMAR) and ≥20/32 (0.2 logMAR), respectively. Of all eyes, 83.8% were within ±0.50D, and 96.4% were within ±1.00 D of emmetropia. Ten patients had postoperative bilateral ametropia of more than 1.00D in each eye, but eight of them still achieved binocular UDVA ≥20/40. Intraoperative events occurred in 14 eyes of 13 patients (per-eye incidence: 0.524% or 1 in 191 eyes). A total of 86 postoperative adverse events occurred in 80 eyes of 53 patients (per-eye incidence 2.996% or 1 in 33 eyes), of which cystoid macular edema was the most common. Only three eyes had CDVA reduced by more than two Snellen lines compared to preoperative CDVA, two of which were not related to cataract surgery. There was no patient with bilateral CDVA loss. Conclusion: In our cohort of patients with visually significant cataracts, ISBCS resulted in good refractive predictability and a low incidence of serious adverse events.

RESUMO

Purpose: To compare the outcomes of the Tecnis Eyhance ICB00 IOL, designed to enhance intermediate vision, to a conventional Tecnis Monofocal ZCB00 IOL. Methods: This retrospective analysis compared two cohorts of patients undergoing lens replacement surgery with bilateral implantation of the Tecnis ICB00 or the Tecnis ZCB00 IOL (383 patients in each group). Monocular and binocular uncorrected distance (UDVA), intermediate (UIVA; 66cm), and near (UNVA; 40cm) visual acuities, refractive predictability, and patient-reported outcomes were compared. A sub-analysis of patients with the Eyhance IOL was performed to compare patients who achieved bilateral emmetropia to those with mini-monovision. One-month postoperative outcomes were analyzed. Results: Both groups had comparable UDVA outcomes. On average, both monocular and binocular UIVAs were approximately one Snellen line better in patients implanted with Eyhance IOL (monocular UIVA: ICB00 0.23 ± 0.18 logMAR, ZCB00 0.33 ± 0.19 logMAR; binocular UIVA: ICB00 0.18 ± 0.18 logMAR, ZCB00 0.26 ± 0.20 logMAR, p < 0.01). Likewise, the mean UNVA was also one Snellen line better with the ICB00 model (monocular UNVA: ICB00 0.51 ± 0.20 logMAR, ZCB00 0.61 ± 0.18 logMAR; binocular UNVA: ICB00 0.42 ± 0.19 logMAR, ZCB00 0.51 ± 0.22 logMAR, p < 0.01). There was no difference between the two groups in overall satisfaction or visual phenomena. A subgroup of patients who achieved mini-monovision with Eyhance IOL had, on average, one Snellen line better UIVA and UNVA compared to patients with bilateral emmetropia. Conclusion: Patients receiving the enhanced monofocal IOL had better intermediate and near vision compared to those receiving the conventional monofocal IOL, with similar levels of patient-reported photic phenomena in both groups.
