PURPOSE: To evaluate visual quality differences between intraocular lenses (IOLs) in patients with previous myopic laser ablations and assess the impact of IOL decentration and tilt on visual quality.
SETTING: University of Valencia, Burjassot, Spain.
DESIGN: Cohort study.
METHODS: An adaptive optics visual simulator was used to simulate the wavefront aberration pattern of 1 aberration-correcting IOL (Acrysof IQ SN60WF), 1 aberration-free IOL (Akreos Adapt AO), and 1 spherical IOL (Triplato) under 5 IOL situations: centered, 0.2 mm and 0.4 mm decentered, and 2 degrees and 4 degrees tilted in eyes with simulated low or high myopic laser corneal ablations. Monocular distance visual acuity at 100%, 50%, and 10% contrast were measured.
RESULTS: Ten eyes of 10 patients were evaluated. When the IOLs were centered, the aberration-correcting IOL provided the best visual quality results in both groups. When the IOLs were misaligned, there was a decrease of visual quality with all simulated IOLs except the aberration-free IOL in the high myopia group. In the misaligned situations, all simulated IOLs obtained comparable visual quality results in both groups.
CONCLUSIONS: The results suggest that in patients with previous myopic laser corneal ablation, aberration-correcting IOLs should be implanted. The decrease in visual quality when these IOLs are decentered or tilted demonstrates the importance of accurate implantation of these IOLs.
