# Effectiveness of Enhanced Monofocal Intraocular Lens with Mini-Monovision in Improving Visual Acuity

## TL;DR

This study shows that a new type of intraocular lens improves intermediate and near vision and reduces the need for glasses after cataract surgery.

## Contribution

The study introduces a new enhanced monofocal intraocular lens in a mini-monovision setup that improves visual outcomes compared to standard lenses.

## Key findings

- The XY1-EM lens improved intermediate and near visual acuity at 30−50 cm distances compared to standard lenses.
- Patients with XY1-EM had reduced spectacle dependence for intermediate distances.
- Higher patient-reported outcomes were observed in vision-related quality of life for XY1-EM users.

## Abstract

Objectives: This study compared the clinical outcomes of Vivinex Impress (XY1-EM) enhanced monofocal and standard Vivinex (XY1) intraocular lenses (IOLs) in mini-monovision cataract surgery. In this retrospective study, patients underwent bilateral implantation with either XY1-EM (33 patients, 66 eyes) or XY1 (24 patients, 48 eyes) in a −1D mini-monovision configuration. Methods: Visual acuity was evaluated from 5 m to 30 cm, along with spectacle dependence, contrast sensitivity, and patient-reported outcomes. Results: The XY1-EM group demonstrated significantly better intermediate and near visual acuity at distances of 30−50 cm (p < 0.05) and reduced spectacle dependence for intermediate distances (p = 0.02). Visual function questionnaire (VFQ-25) scores were significantly higher in the XY1-EM group for general vision, role difficulty, mental health, dependency, and near activity domains (p < 0.05). No significant differences were found in glare, contrast sensitivity, or quality of vision scores. Conclusions: The XY1-EM lens in mini-monovision configuration provides enhanced intermediate and near visual acuity with reduced spectacle dependence compared to standard monofocal IOLs, offering a valuable option for patients seeking improved quality of vision with reduced spectacle use.
