# Visual efficacy after implantation of monofocal intraocular lens on one eye and higher-order aspheric IOL on the other eye

## TL;DR

This study compares the visual outcomes of two types of intraocular lenses implanted in different eyes and finds that combining them improves vision and daily satisfaction.

## Contribution

The study introduces a novel approach of combining different intraocular lenses in each eye to enhance visual performance.

## Key findings

- The ZCB00 lens showed better uncorrected near vision compared to the Eyhance ICB00 lens.
- The Eyhance ICB00 lens provided better uncorrected intermediate vision than the ZCB00 lens.
- Patients reported no limitations in daily activities with either lens combination.

## Abstract

To compare visual and refractive outcomes and patient satisfaction results after binocular cataract surgery with implantation of both TECNIS Eyhance ICB00 and TECNIS ZCB00 intraocular lenses in the same patient.

One hundred twelve eyes from 56 patients who underwent intraocular lens implantation with Eyhance ICB00 and ZCB00 in the same patient were retrospectively enrolled. Pre-operative and post- operative uncorrected and corrected near (UNVA, CNVA), intermediate (UIVA, CIVA), distant (UDVA, CDVA) visual acuity, and depth of focus were analyzed. Satisfaction surveys were evaluated after cataract surgery.

There was no significant difference in the preoperative values between the Eyhance ICB00 and ZCB00 groups. At two months postoperatively, UNVA of the ZCB00 group (0.02 ± 0.03 logMAR) was significantly better than that of the Eyhance ICB00 group (0.05 ± 0.05) (P < 0.05). At one week, one month, and two months postoperatively, the UIVA of the Eyhance ICB00 was significantly better than that of the ZCB00 group (P < 0.05). At two months postoperatively, the UNVA of the Eyhance ICB00 was significantly better than that of the ZCB00 group (P < 0.05). In the satisfaction survey, daily activities were not limited by their vision or glare in both groups.

Inserting a high-aberration aspheric intraocular lens(IOL) in one eye rather than inserting a monofocal IOL in both eyes is better for improving distance, intermediate, and near vision. Furthermore, patients who have Eyhance ICB00 in one eye and a monofocal IOL in the other do not experience any difficulty in their daily lives.
