Visual, Clinical, and Quality of Life Outcomes of a New Multifocal IOL

Study Overview

This study focuses on the BIOS Trifocal intraocular lens (IOL), designed to help patients see clearly at various distances without needing glasses. The lens aims to minimize issues like halos and glare, which can occur with other multifocal lenses.

Key Features of BIOS Trifocal IOL

Single-piece acrylic design: Enhances stability and centration.
Aspheric surface: Reduces visual distortions.
Optimized diffraction grating: Distributes light effectively for clear vision at all distances.

Study Methods

Participants received the BIOS Trifocal IOL and were evaluated at 30 and 90 days after surgery. Assessments included:

Patient-reported outcomes using the NEI-VFQ 25 questionnaire.
Visual acuity tests for distance and near vision.
Monitoring of any complications during and after the procedure.

Results

The results showed:

Significant improvement in distance and near vision at both 30 and 90 days (p < 0.001).
Functional vision maintained across a range of distances, from +1.5 D to -3.0 D.
Quality of life improvements in all areas measured (p < 0.05).
No major complications linked to the IOL.

Conclusions

The BIOS Trifocal IOL effectively treats cataracts and presbyopia, providing clear vision at various distances and high patient satisfaction.
