Objective:
To evaluate the outcomes of bilateral Tecnis PureSee IOLs in patients with ocular comorbidities.
Approach:
- Study Design: Retrospective analysis of 418 patients who underwent bilateral refractive lens exchange (RLE) with a history of various ocular and systemic comorbidities.
Key Findings:
- Mean uncorrected binocular visual acuity was -0.002 logMAR at distance, 0.131 logMAR at intermediate, and 0.224 logMAR at near, two months post-surgery.
- 95.7% of patients achieved 0.20 logMAR (20/32 Snellen) or better at distance, 78.0% at intermediate, and 45.5% at near.
- Distance and intermediate vision performance remained stable across different comorbidities, while near vision was most affected in patients with macular disease.
- The PureSee lens's non-diffractive optical design preserves contrast sensitivity and has a low incidence of bothersome halos and dysphotopsias.
Limitations:
- Patients may achieve lower levels of spectacle independence compared to those receiving diffractive IOLs, especially for near vision.
- Careful counselling is required to manage patient expectations regarding spectacle independence.
