Purpose

To investigate the refractive and visual outcomes of a monofocal, optimized, aspheric, intraocular lens (IOL) implanted in eyes with different degrees of corneal spherical aberration after cataract surgery.

Setting

Oftalvist, Valencia, Spain

Methods

This prospective study was approved by the Ethics Committee of the Hospital Clínico San Carlos and registered at DRKS00032562. The inclusion criteria considered, age-related cataract patients, corneal astigmatism up to 1.00D, and IOL power to be implanted ranging from 0 to 34D. The exclusion criteria considered, irregular cornea, a history of previous corneal refractive surgery, ocular anomalies or pathologies that could reduce visual function or postoperative IOL stability. 54 eyes were implanted with the CT LUCIA 621P IOL and analyzed at 3-months post-surgery. Eyes were categorized into 3 groups (18 eyes/group) based on their corneal SA (6-mm pupil): group A (0 to 0.2 mm), group B (>0.2 to 0.4 mm), and group C (>0.4 to 0.6 mm).

Results

Corrected distance visual acuity was similar between groups, showing mean values of –0.02±0.04, –0.04±0.05 and 0.01±0.11 logMAR, for groups A, B, and C, respectively (P=0.094). In relation to accuracy, group A showed 88.89% of eyes within ±1.00D of spherical equivalent and with a refractive astigmatism of ≤1.00D, group B showed 94.4%, and, group C 88.89% of eyes were within ±1.00D and 94.4% of eyes ≤1.00D. Contrast sensitivity functions were good for the three groups being similar for all spatial frequencies analyzed (P>0.01). The area under the 7‑point defocus curves, both for photopic and mesopic lighting conditions, did not differ between groups  (P>0.5). All patients reported being either very or quite satisfied with their vision.

Conclusions

The outcomes obtained suggest that different degrees of corneal spherical aberration do not affect the visual performance of eyes implanted with the CT LUCIA 621P IOL.
