Abstract

Purpose

To compare postoperative clinical outcomes between 2 types of 3-piece aspheric intraocular lenses.

Methods

Uncorrected visual acuity, best corrected visual acuity, total ocular and internal ocular aberration including higher-order aberrations and spherical aberration, and modulation transfer functions were compared 6 months after cataract surgery between eyes implanted with TECNIS ZA9003 (group 1) and HOYA PC-60AD (group 2) in 30 and 28 eyes, respectively, In addition, the differences between postoperative spherical equivalent and preoperative target refractive errors were analyzed.

Results

Clinical outcomes showed no significant differences between both groups including visual acuities, high order aberrations, and modulation transfer function. In both groups, postoperative refractive errors were more of a myopic state than preoperative estimated target refraction. The myopic refractive error between both groups showed no significant difference (-0.26 vs. -0.42 diopter, p = 0.75).

Conclusions

The newly developed 3-piece aspheric IOL, HOYA PC-60AD shows similar clinical outcomes compared with the widely used 3-piece IOL TECNIS ZA9003.

Keywords: High order aberration, Modulation transfer function, Spherical aberration, 3-piece intraocular lens
