Abstract

PURPOSE
To compare the visual function and postoperative refraction between two aspheric intraocular lenses (IOLs) after microcoaxial cataract surgery.
METHODS
A prospective analysis of 60 eyes of 58 patients who had undergone microcoaxial phacoemulsification and implantation of aspheric IOLs (AcrySof IQ, 30 eyes; Akreos MI60, 30 eyes) was performed. The best corrected visual acuity (BCVA), spherical equivalent, intraocular pressure (IOP), corneal thickness, endothelial cell density (ECD), predictability of postoperative spherical equivalent, higher order aberrations, contrast sensitivity test, satisfaction, and glare were evaluated during the follow-up period of three months.
RESULTS
There were no significant differences in BCVA, spherical equivalent, IOP, corneal thickness, or ECD (p>0.05). The predictability of the postoperative spherical equivalent in the AcrySof IQ and Akreos MI60 IOL groups was not significantly different (p=0.59), and the two groups showed good anterior-posterior stability during the postoperative three months. There were no significant differences in higher order aberrations, contrast sensitivity test, satisfaction or glare (p>0.05).
CONCLUSIONS
Both AcrySof IQ and Akreos MI60 implantation groups showed similar visual functions and postoperative spherical equivalents after microcoaxial cataract surgery.
