- Abstract
- PURPOSE: To compare the mean effective lens position (ELP) and actual amount of axial movement of 3 aspheric intraocular lenses (IOLs) using anterior segment optical coherence tomography (AS-OCT). SETTING: Department of Ophthalmology, Korea University College of Medicine, Seoul, South Korea. DESIGN: Retrospective comparative study. METHODS: Consecutive patients had phacoemulsification with aspheric IOL implantation. The ELP measurements by AS-OCT were taken 1 week and 1, 3, and 6 months postoperatively. The ELPRMS was defined as the root mean square (RMS) of the change in ELP at each follow-up timepoint. RESULTS: An XL Stabi ZO 3-plate IOL was implanted in 30 eyes, an Acrysof IQ C-loop IOL in 22 eyes, and an Akreos MI-60 4-plate IOL in 17 eyes. The 4-plate IOL showed significant changes in the mean ELP from 1 week to 1 month and from 3 to 6 months postoperatively (P=.005 and P=.028, respectively). The changes of the other 2 IOLs were insignificant during the 3 postoperative visits. However, the mean ELPRMS of the C-loop IOL (0.06 mm +/- 0.31 [SD]) was smaller than that of the 3-plate IOL (0.14 +/- 0.28 mm) and the 4-plate IOL (0.20 +/- 0.35 mm) (P=.014 and P=.023, respectively) during the 3 timepoints. CONCLUSION: An appropriate method based on the actual amount of axial IOL movement, such as the ELPRMS, is needed to assess the axial positional stability of IOLs.
