Abstract

Purpose: : To investigate the influence of tilt and decentration of capsular capture of intraocular lenses (IOLs) on ocular higher-order wavefront aberration.

Methods: : In 17 eyes of 16 patients who had been diagnosed as capsular capture of IOLs (aspherical IOLs 10 cases, spherical IOLs 7 cases), and 91 eyes of 76 patients after cataract surgery with posterior chamber IOL implantation (aspherical IOLs 77 cases, spherical IOLs 24 cases), tilt and decentration of IOLs were determined by Scheimpflug vidiophotography (EAS-1000), and higher-order wavefront aberration for a 4-mm pupil and 6-mm pupil were measured using Hartmann-Shark aberrometer (KR9000PW TOPCON).

Results: : In eyes with capsular capture IOLs, the mean (SD) tilt angle was 4.96 (2.30) degree, which was significantly higher than that of the normal cataract surgery group 3.27 degree (P<0.05), and the mean (SD) decentration was 0.24 (0.13) mm. And in Ocular coma-like aberration were 0.129 (0.061) microm in 4-mm pupil and 0.418 (0.385) microm in 6-mm pupil, which was significantly greater than normal group in 6-mm (0.291 microm). Ocular trefoil-like aberration were 0.164 (0.110) microm in 4-mm pupil and 0.529 (0.365) microm in 6-mm pupil. No significant correlated was found with tilt/decentraion and aberration in 4-mm pupil. IOL decentration significantly correlated with trefoil-like aberration (R=0.704.P=0.001), IOL tilting correlated with coma-like aberration in 6-mm pupil(R=0.621.P=0.01).

Conclusions: : n eyes with capsular capture of IOL, it had greater tilting angle and coma-like aberration than normal cataract surgery group. Tilting of IOL induces considerable coma-like aberration and decentration induces trefoil-like aberration.
