Wavefront-guided photorefractive keratectomy to correct ametropia following aspheric ReSTOR implantation

J Refract Surg. 2009 Dec;25(12):1111-5. doi: 10.3928/1081597X-20090728-01.

Abstract

Purpose: To describe the clinical course of three eyes of two patients who underwent wavefront-guided photorefractive keratectomy to correct ametropia following cataract extraction and aspheric ReSTOR lens (SN6AD3; +4.00-diopter model) implantation.

Methods: Pre-and postoperative uncorrected visual acuity (UCVA) and best spectacle-corrected visual acuity (BSCVA), manifest refraction, and WaveScans based on the Hartmann-Shack analyzer were evaluated. The VISX STAR S4 excimer with eye tracking and iris registration was used in all cases.

Results: Good quality WaveScans were obtained; UCVA improved in all cases and BSCVA improved or remained unchanged.

Conclusions: These cases demonstrate that it is possible to obtain good quality wavefront data in patients with the ReSTOR lens and to use such data to design wavefront-guided treatment to maximize uncorrected distance and near visual acuities after ReSTOR implantation.
