Outcomes of mini-monovision with monofocal, enhanced monofocal and extended depth-of-focus intraocular lenses
PurposeMini-monovision is a vision correction technique that allows for a broader spectrum of spectacle independence while minimizing anisometropia. This systemic review aims to evaluate the clinical outcomes of pseudophakic mini-monovision with three types of intraocular lenses (IOLs): monofocal, enhanced monofocal, and extended depth of focus (EDOF).MethodsA comprehensive literature search was conducted using PubMed and MEDLINE to identify studies reporting mini-monovision outcomes within the three categories of IOLs up to July 2024. Inclusion criteria were studies with more than 20 patients, target refraction to achieve mini-monovision difference in the fellow eye, and minimum follow-up of 3 months. The primary outcome measure was uncorrected binocular intermediate visual acuity (UCIVA). The secondary outcomes were binocular uncorrected distance visual acuity (UCDVA), binocular uncorrected near visual acuity (UCNVA), patient-reported outcomes measures (PROMs), spectacle independence, contrast sensitivity, photic phenomenon, enhancement surgeries and IOL exchange.ResultsA total of 113 studies were screened, of which 19, with a total of 1,530 patients, were eligible for inclusion in this review. Mean logMAR binocular UCIVA was 0.16 ± 0.01, 0.11 ± 0.06, 0.08 ± 0.07 (p = 0.41), and mean logMAR UCDVA was 0.08 ± 0.05, 0.04 ± 07, 0.04 ± 0.04 (p = 0.36), in the monofocal, enhanced monofocal, and EDOF groups, respectively. The mean spectacle independence rate was 51% ± 22.1, 55% ± 35.4 and 63.4% ± 24.6 (p = 0.05), respectively, in the monofocal, enhanced monofocal and EDOF groups. A comparable low incidence of halos and glare was observed when enhanced monofocal lenses were evaluated against traditional monofocal lenses. EDOF lenses have, however, demonstrated mixed results. The complications, IOL exchange, and excimer laser enhancement rates were low across all groups.ConclusionWhile enhanced monofocal and EDOF IOLs may provide slightly better binocular intermediate visual outcomes and higher spectacle independence compared to monofocal lenses with regards to mini-monovision and intermediate vision performance, the differences are not statistically significant. All three IOL types exhibit high patient satisfaction rates when choosing a mini-monovision approach with decreased dependence on spectacles
Outcomes of Descemet's membrane endothelial keratoplasty performed in combination with, before, or after cataract surgery in Fuchs' endothelial dystrophy: A review of the literature and meta-analysis
This review aimed to compare the outcomes of Descemet's membrane endothelial keratoplasty (DMEK) in combination with (category 1), before (category 2), or after cataract surgery (category 3) in patients with Fuchs' endothelial dystrophy (FED). Primary outcome was gain in best-corrected log of minimum angle of resolution (logMAR) visual acuity (BCVA). Secondary outcomes were graft detachment, rebubbling rates, rejection, failure, and endothelial cell loss (ECL). In category 1, 2, and 3, 12 studies (N = 1932) were included (five in category 1 [n = 696], one in category 2 [n = 286], and two in category 3 [n = 950], and the remaining four compared between two of the three categories). At 6 months, the gain in BCVA was 0.34 ± 0.04, 0.25 ± 0.03, and 0.38 ± 0.03 logMAR in category 1, 2, and 3, respectively. The difference was significant between categories 1 and 2 (Chi2 = 11.47, P < 0.01) and categories 2 and 3 (Chi2 = 35.53, P < 0.01). At 12 months, the gain in BCVA was 0.52 ± 0.05 and 0.38 ± 0.06 logMAR in categories 1 & 3 (Chi2 = 14.04, P < 0.01). The rebubbling rates were 15%, 4%, and 10% (P < 0.01) and the graft detachment rates were 31%, 8%, and 13% (P < 0.01) in categories 1, 2, and 3, respectively. However, graft rejection, survival rates, and ECL at 12 months were not different between categories 1 and 3. There is low certainty evidence that gain in BCVA in category 1 was comparable to category 3 at 6 months; however, it was significantly better with category 3 at 12 months. Although rebubbling and graft detachment rates were highest in category 1, there was no significant difference in graft rejection, survival rates, and ECL. Further high-quality studies are likely to change the effect estimate and have an impact on the confidence of the estimate
Optical aberrations following implantation of multifocal intraocular lenses: a systematic review and meta-analysis protocol
INTRODUCTION: Multifocal intraocular lens (IOLs) are used to restore vision at different focal distances. The technology of multifocal IOLs is continually advancing. Optical aberrations a property of lenses that causes spreading of light over a region resulting in a blurred or distorted image. This study aims to systematically review investigator measured and patient reported optical aberrations following implantation of multifocal IOLs during phacoemulsification surgery to treat presbyopia in adults. METHODS AND ANALYSIS: We will conduct an electronic database search for randomised controlled trials, prospective non-randomised studies, observational studies in Ovid MEDLINE, Ovid EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Scopus and ClinicalTrials.gov in March 2021. Eligibility criteria will include quantitative articles written in English and containing data on optical aberrations. Two independent reviewers will screen titles and abstracts and extract data from full texts, reporting outcomes according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data extraction of key characteristics will be completed using customised forms. Methodological quality will be assessed using Cochrane Handbook 6.2. ETHICS AND DISSEMINATION: Ethics approval is not required for this review, as it will only include published data. Findings will be published in a peer-reviewed journal and disseminated across ophthalmic networks. We anticipate that the findings of this work will be of interest to multiple stakeholders: people who have undergone cataract surgery, eye health professionals, ophthalmic surgeons, device manufacturers and policy-makers. It will also inform researchers to where there are gaps in evidence and identify areas for future research. PROSPERO REGISTRATION NUMBER: CRD42021271050

The trial was funded by the National Institute of Health Research (NIHR) Health Technology Assessment Panel (project reference number HTA 13/04/46 and was sponsored by University College London (UCL).Purpose To report the 3-month results of a randomized trial (Femtosecond Laser-Assisted Cataract Trial [FACT]) comparing femtosecond laser-assisted cataract surgery (FLACS) with standard phacoemulsification cataract surgery (PCS). Design Multicenter, randomized controlled trial funded by the UK National Institute of Health Research (HTA 13/04/46/). Participants Seven hundred eighty-five patients with age-related cataract. Methods This trial took place in 3 hospitals in the UK National Health Service (NHS). Randomization (1:1) was stratified by site, surgeon, and 1 or both eyes eligible using a secure web-based system. Postoperative assessments were masked to the allocated intervention. The primary outcome was unaided distance visual acuity (UDVA) in the study eye at 3 months. Secondary outcomes included corrected distance visual acuity, complications, and patient-reported outcomes measures. The noninferiority margin was 0.1 logarithm of the minimum angle of resolution (logMAR). ISRCTN.com registry, number ISRCTN77602616. Main Outcome Measures We enrolled 785 participants between May 2015 and September 2017 and randomly assigned 392 to FLACS and 393 to PCS. At 3 months postoperatively, mean UDVA difference between treatment arms was −0.01 logMAR (−0.05 to 0.03), and mean corrected distance visual acuity difference was −0.01 logMAR (95% confidence interval [CI], −0.05 to 0.02). Seventy-one percent of both FLACS and PCS cases were within ±0.5 diopters (D) of the refractive target, and 93% of FLACS and 92% of PCS cases were within ±1.0 D. There were 2 posterior capsule tears in the PCS arm and none in the FLACS arm. There were no significant differences between arms for any secondary outcome. Conclusions Femtosecond laser-assisted cataract surgery is not inferior to conventional PCS surgery 3 months after surgery. Both methods are as good in terms of vision, patient-reported health, and safety outcomes at 3 months. Longer-term outcomes of the clinical effectiveness and cost-effectiveness are awaited.Publisher PDFPeer reviewe

Clinical Dilemmas in the Management of a Monocular Patient with Down's Syndrome, Dementia, Advanced Keratoconus, and a Mature Cataract
ABSTRACT
There are reports on the successful management of mild to moderate keratoconus in patients with Down's syndrome. However, when Down's syndrome is coexistent with Dementia, poor general health, and very advanced keratoconus in only one eye, then clinicians may face challenges at all stages from diagnosis, treatment, and follow-up. Our case is one such example of a combination of Down's syndrome, Dementia, poor general health, and very advanced keratoconus with a white cataract in the only functioning eye. This report highlights the dilemmas which were encountered and learning points on selection of the safest, yet effective management options in such patients.
