Abstract

Purpose: to evaluate the changes in contrast sensitivity and wavefront high-order aberrations of eyes implanted with aspheric intraocular lenses in comparison with those with standard spherical intraocular lenses.

Methods: The 40 patients' eyes were included in this comparative prospective investigation. There were two sets of participants in this study, A and B, each with an equal number of eyes. (20). Group (A): underwent standard phacoemulsification with the implantation of an AcrySof IOL (SA60AT), a single-piece, spherical monofocal IOL Alcon Laboratories, Inc. The AcrySof IQ IOL (SN60WF), an aspheric monofocal IOL, was implanted in Group B using standard phacoemulsification techniques; Alcon Laboratories, Inc. At Al Hussein University Hospital, where the study was conducted, the same surgeon operated on each case.

Results: At the 3-month follow-up, both groups' mean uncorrected visual acuity(UCVA) and best corrected visual acuity(BCVA) considerably rose from the preoperative value. The mean postoperative UCVA and BCVA in each group were not significantly different from one another (P > 0.05). Total aberrations (p = 0.020) and high order aberrations (HOA)(p = 0.042) were statistically different between the groups under study, with aspheric values being lower for 3mm pupils. Our investigation revealed a very statistically significant reduction in spherical aberrations (SA) values in the aspheric group with a 3mm and 5mm pupil. According to our research, there was no statistically significant (NS) change in photopic contrast sensitivity (CS) between the 2 intraocular lenses (IOLs) postoperatively (p=0.575).

Conclusion: As comparison to spherical IOLs, aspheric IOLs greatly reduced HOA, notably at 5mm pupil diameter, and significantly reduced SA at both pupil sizes.
