Abstract Details



Purpose:

To evaluate the visual performance of an aberration-free intraocular lens (IOL) in patients with different corneal profiles using adaptive optics (AO) visual simulation.

Setting:

University of Valencia

Methods:

A CRX1 AO visual simulator (Imagine Eyes, France) was used to simulate the aberrationÂ’s pattern of an aberration-free IOL combined with five corneal profiles: virgin corneas and corneas with low and high myopic ablations and low and high hyperopic ablations. Monocular distance visual acuity (VA) at 100%, 50% and 10% of contrast were measured

Results:

Ten eyes of ten subjects were evaluated. At 100% of contrast, differences were not found in VA values among: virgin corneas, low and high myopic ablations and low hyperopic ablation groups (P=0.06). All these groups achieved better results than the high hyperopic ablation group (P< 0.001). At 50% and 10% the best values of VA were obtained for the virgin corneas and for the low myopic and hyperopic ablations groups (P>0.1, for both levels of contrast). Statistically significant differences were found between these three corneal profiles and the other two corneal profiles (P<0.002 for the high myopic and P<0.001 for the high hyperopic, for both levels of contrasts).

Conclusions:

The results suggests that the aberration-free IOL design provides an excellent visual performance for a range of corneal SA that could correspond to patients with virgin corneas and to patients in which the corneal SA has been slightly modified by a hyperopic or myopic laser ablation. However, in patients with higher amounts of corneal SA other IOL design should be chosen. FINANCIAL DISCLOSURE?: No
