Materials and Methods: In total, 20 eyes of 20 patients (11 women, 9 men) who had undergone scleral-fixated IOL implantation surgery to correct aphakia between January 2004 and September 2009 were included in the study. All of the surgeries were conducted by same surgeon in the Cerrahpasa Faculty of Medicine, Department of Ophthalmology at Istanbul University. The average age of the patients was 55.05, and patients ranged in age from 11 to 78 years. Patients were divided two groups.Group 1 (11 eyes): Patients had foldable scleral-fixated intraocular lens,group 2 (9 eyes): Patients had unfoldable scleral-fixated intraocular lens. Informed consent was obtained from each of the patients included in the study. Detailed biomicroscopy and fundus examinations were performed. A Keratron Scout videokeratoscope was used to measure corneal topography, and ORK wavefront device was used to measure optical aberrations.

Results: There is no significant difference for Coma (μ), Trefoil (μ) and Spherical aberrations (μ) between two groups (p values are respectively 0.370; 0.199 and 0.503).

Conclusions: Foldable or unfoldable scleral-fixated intraocular lens implantation surgery induces High-order aberrations. This information may provide better understanding of the optical performance of eyes implanted with scleral-fixated IOLs The weakness of this retrospective study is that various types of IOLs were used and The number of patients were limited in our study. Further studies are warranted. Keywords : Wavefront aberrations,scleral-fixated lens,cataract
