Abstract

Purpose

To evaluate the changes in higher-order aberrations (HOAs) after implantation of an ICL (implantable contact lens).

Methods

Twenty-six eyes that had undergone ICL implantation between February 2008 and October 2009 were included. Ocular higher-order aberrations of all the eyes were measured using the Hartmann-Shack aberrometer (KR9000PW). Examinations were performed preoperatively, as well as one week, one month, and three months after ICL implantation. Changes in ocular total higher-order aberrations, total spherical aberration, coma aberration, trefoil aberration, and S3 and S4 calculated in the central 4-mm zone and expressed as root mean square (RMS) values were analyzed.

Results

The mean patient age was 25.4 years, and the mean preoperative spherical equivalent was -6.40 diopters(D). The mean postoperative spherical equivalents were 0.00 ± 0.13D, 0.03 ± 0.21D, -0.013 ± 0.12D at one week, one month,and three months, respectively. There were no statistically significant differences in ocular higher-order aberration RMS,including spherical, coma, or trefoil aberration, at one week, one month, or three months postoperative or between preoperative and postoperative measurements.

Conclusions

There is no significant change of ocular higher order aberration in the central 4-mm zone after ICL implantation.
