AI Article Synopsis
- The study aimed to compare the outcomes of enhanced monofocal intraocular lenses (IOLs) against conventional monofocal IOLs after cataract surgery, focusing on visual acuity, spectacle independence, and adverse effects.
- Researchers used PRISMA guidelines to examine data from various studies, finding that enhanced IOLs resulted in better uncorrected intermediate visual acuity and more patients achieving spectacle independence at intermediate distances compared to conventional IOLs.
- Despite the improved intermediate vision, both types of IOLs showed similar performance in distance vision, contrast sensitivity, and adverse effects, indicating the enhanced IOLs provide benefits without negative trade-offs.
Article Abstract
Purpose: To compare different outcomes of an enhanced monofocal intraocular lens (IOL) versus a conventional monofocal IOL implantation after cataract surgery.
Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guideline was used for abstracting data and assessing quality. Comparative studies between enhanced monofocal versus conventional monofocal IOL implantations reporting outcomes in monocular and binocular visual acuities at various distances, spectacle independence, contrast sensitivity, optical quality, and adverse effects were identified from three databases. Meta-analysis, sensitivity analysis, and subgroup analysis were performed.
Results: A total of 680 eyes implanted with an enhanced monofocal IOL (Tecnis Eyhance ICB00; Johnson & Johnson) and 647 eyes with a conventional monofocal IOL from 3 randomized controlled trials and 9 comparative studies were included. The enhanced monofocal IOL showed better monocular uncorrected intermediate visual acuity (UIVA) (mean difference [MD]: -0.11 logMAR; 95% CI: -0.12 to -0.09), binocular UIVA (MD: -0.17 logMAR; 95% CI: -0.23 to -0.11), and binocular uncorrected near visual acuity performance (MD: -0.17 logMAR; 95% CI: -0.29 to -0.04) than the conventional monofocal IOL. More patients were spectacle free at intermediate distance with the enhanced monofocal IOL (odds ratio: 12.9; 95% CI: 6.2 to 27.0). Both monocular (MD: -0.002 logMAR; 95% CI: -0.01 to 0.01) and binocular (MD: 0.01 logMAR; 95% CI: -0.02 to 0.03) uncorrected distance visual acuity revealed non-significant differences between the IOL designs. Contrast sensitivity, photic phenomenon, and adverse effects were comparable.
Conclusions: Enhanced monofocal IOLs effectively improved unaided intermediate vision with similar distance performance relative to conventional monofocal IOLs. This was achieved without compromising the contrast sensitivity or inducing photic phenomena. .

Cataract surgery involves the implantation of an intraocular lens (IOL) to replace the opacified crystalline lens. Monofocal IOLs, the most common type, are intended to have the eye in focus at a given distance, usually at infinity. Simultaneous vision IOLs (SVIOLs) and extended depth of focus (EDOF) aim to minimize postoperative dependence on spectacles by providing either multiple foci or an extended depth of focus.

Article Synopsis
- The study aimed to compare the clinical outcomes of three different types of intraocular lenses (IOLs) used in cataract surgery: bilateral hybrid multifocal IOLs, a mix of enhanced depth of focus and hybrid multifocal, and a mix of enhanced monofocal and hybrid multifocal.
- 75 patients were randomly assigned to one of the three groups and assessed after 6 months for various visual acuity measures, reading speed, and quality of vision.
- Results indicated that while bilateral hybrid multifocal IOLs provided better near vision, they also caused more visual disturbances like starbursts compared to the mix-and-match options, suggesting that different IOL combinations could cater to individual patient needs.

This study presents a systematic method to simulate various intraocular lenses (IOLs) available in the market. Five IOLs (two trifocals, one bifocal, one enhanced monofocal, and one extended depth of focus (EDOF)) were evaluated in terms of through focus visual Strehl (TFVS) utilizing the OptiSpheric IOL PRO2 device (Trioptics GmbH). Then, the estimated TFVS (ETFVS) and the temporal coefficients necessary for temporal multiplexing were computed, and through an iterative process, the SimVis TFVS was obtained.

Article Synopsis
- * Significant improvements in uncorrected and corrected distance visual acuity were noted three months post-surgery, with a notable 81.9% reduction in astigmatism measurements.
- * The findings suggest that this new enhanced monofocal toric IOL is a safe and effective option for treating astigmatism in cataract patients.
