Comparison between clinical outcomes of two different designs of toric multifocal intraocular lenses

Abstract

To compare the clinical outcomes of plate haptic and open-loop haptic toric multifocal intraocular lenses (IOLs). In this retrospective, comparative clinical trial, two different designs of multifocal toric IOL were implanted in 49 eyes of 38 cases with corneal astigmatism ≥ 0.75 Diopter (D). The cases that underwent AcrySof IQ restore multifocal toric IOL (Alcon, open-loop-haptic) implantation were assigned to Group1 (n=19) and the cases that underwent Acriva Reviol multifocal toric IOL (VSY, plate-haptic) implantation were assigned to Group 2 (n=30). After surgery, the groups were compared in terms of degree of IOL rotation, residual spherical refraction and astigmatism and uncorrected near and distance visual acuity. With regard to the results of postoperative 1st month, 3rd month, 6th month and 1st year, no difference was determined in terms of uncorrected distance visual acuity, spherical equivalent (SE), degree of astigmatism (CYL), degree of rotation, and uncorrected near visual acuity (p>0.05). Significant increase was determined in all postoperative follow-up periods in terms of the distance and near visual acuity as compared to preoperative values (p<0.05). There was no correlation between degree of rotation and age, axial length, SE and CYL (p>0.05). Clinical outcomes of plate haptic Acriva Reviol multifocal toric IOL and open-loop haptic Acrysof IQ multifocal toric IOL are similar. Both types of IOL effectively reduce astigmatism and provide satisfactory uncorrected distance and near visual acuities.
