Abstract

Background: The goal of cataract surgery today is not only to restore visual acuity but also to provide the best quality of vision possible. With modern techniques and advancements in the manufacture of Intra Ocular Lenses (IOLs), improvement in patients’ visual performance and quality of life has become the main goals after cataract surgery.

Method: 70 eyes of 70 patients (35 aspheric IOL and 35 spherical IOL) between the age group of 45 - 73 years with BCVA of 6/6 at postoperative period of 3 months were enrolled in the study. HD -Analyzer was used to measure the optical quality, FACT for checking the contrast sensitivity and i-Trace for measuring the spherical aberration. Informed consent was obtained from all participants. For each case Pro Forma sheet including patient’s demographic data, best corrected visual acuity and type of IOL implanted were maintained.

Results: There was significant better contrast sensitivity, optical quality and less of spherical aberration in patient who were implanted with aspheric IOL than compare to the patients implanted with spherical IOL.

Conclusion: After the postoperative period of 3 months, patient with aspheric IOL were found to have good optical quality, contrast sensitivity and reduced spherical aberration than those of spherical IOL group.

Keywords: Optical Quality; Contrast Sensitivity; Spherical Aberration; Spherical IOL and Aspheric IOL
