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.
