Posterior Capsular Opacification and Nd: YAG Laser Capsulotomy in 811B, SI40NB, MA60BM Intraocular Lens

ABSTRACT

PURPOSE: To compare the incidence and the interval between the development of posterior capsular opacification (PCO) and Nd YAG laser capsulotomy among patients implanted with a 811B, SI40NB, and MA60BM intraocular lens METHODS: One hundred ninty eyes of 157 patients who had undergone implant surgery with 811B, SI40NB, and MA60BM intraocular lens at the Presbyterian Medical Center were studied retrospectively. We compared the postoperative best corrected visual acuity, the incidence and the time interval between the development of PCO and laser capsulotomy, and the total energy used in laser capsulotomy among three intraocular lens groups. RESULTS: The incidence of development of PCO was 26.9% in 811B, 23.8% in SI40NB, and 10% in MA60BM groups, showing that incidence was significantly lower in the MA60BM group as compared to 811B (P=0.0016) or SI40NB (P=0.0056) group. The 811B group induced PCO earlier than SI40NB group. The energy used in Nd YAG laser capsulotomy was lower in 811B than that in SI40NB or MA60BM. CONCLUSIONS: The incidence of posterior capsular opacification and that of Nd YAG laser capsulotomy were found to be significantly lower in the MA60BM group than those in 811B or SI40NB group.
