# Bilateral implantation of extended depth of focus intraocular lens in patients with early or intermediate age-related macular degeneration

## TL;DR

This study shows that implanting a specific intraocular lens in patients with early or intermediate AMD improves vision and reduces visual disturbances.

## Contribution

Demonstrates the effectiveness of AcrySof IQ Vivity IOL in AMD patients with cataracts.

## Key findings

- mCDVA improved significantly from 0.30 to 0.00 logMAR post-surgery.
- 91.7% of patients reported satisfaction with the postoperative results.
- Spectacle independence was achieved for distance and intermediate tasks by most patients.

## Abstract

To evaluate the visual outcomes, dysphotopsia profile, and patient satisfaction following bilateral implantation of the AcrySof IQ Vivity intraocular lens (IOL) in patients with early or intermediate age-related macular degeneration (AMD).

Prospective, single-center study. 24 patients (48 eyes) with bilateral cataract and early or intermediate AMD who underwent bilateral implantation of the AcrySof IQ Vivity IOL. The primary outcome was monocular corrected distance visual acuity (mCDVA). Secondary endpoints were distance-corrected and unaided monocular and binocular visual acuity at 4 m, 66 cm, and 40 cm, monocular defocus curve, subjective dysphotopsia (McAlinden QoV questionnaire) and haloes perception (Aston Halometer), visual function (Catquest-9SF), and spectacle independence (IOLSAT).

At 3 months postoperatively, mCDVA improved significantly from 0.30 to 0.00 logMAR (p < 0.001). Binocular uncorrected distance and intermediate visual acuities of ≤ 0.2 logMAR were achieved by 23 (95.8%) and 17 (70.8%) patients, respectively. The defocus curve showed visual acuity of 0.2 logMAR across a range of + 1.40 D to -1.72 D. Bothersome dysphotopsias significantly decreased, with QoV scores improving from 58.5 (IQR: 26.1–66.5) to 0.00 (IQR: 0.00–14.3) (p < 0.05). The mean halo eccentricity was 0.50 ± 0.08 degrees. Spectacle independence was reported by 22 (91.7%), 20 (83.3%), and 13 (54.2%) patients for distance, intermediate, and near tasks, respectively. Overall, 22 (91.7%) patients reported postoperative satisfaction.

The AcrySof IQ Vivity IOL demonstrated favourable outcomes in patients with early or intermediate AMD, offering a meaningful range of spectacle-free vision with minimal photic phenomena.
