Abstract

Aims: This retrospective study was conducted to compare postoperative surface scattering of four kinds of intraocular lens (IOL).

Methods: Sixty-seven eyes of 67 patients who had undergone cataract surgery were enrolled in this study. One of four IOLs was used in the patients; MA60BM in 17 patients (MA group), SA60AT in 17 patients (SA group), AR40 in 16 patents (AR group) and ClariFlex in 17 patients (CL group). Measurement of scattering from the anterior surface of the IOL was measured with area densitometry using a Scheimpflug camera (EAS-1000, Nidek, Aichi) for 3 years after the surgery.

Results: The density of IOL surface scattering increased starting 1 year after surgery and throughout the 3-year period in the MA group and starting at 6 months through 3 years in the SA group, whereas the density was stable in the AR and CL groups. The density of surface scattering in the MA and SA groups at 3 years after surgery was significantly higher than in the AR and CL groups.

Conclusion: The surface scattering of MA60BM and SA60AT is higher than that of AR40 and ClariFlex. The grades of surface scattering differ among the manufacturers, even with the same acrylic material.
