Abstract Details


We previously reported the posterior capsulotomy rate for the treatment of posterior capsule opacification (PCO) with the acrylic intraocular lenses (IOLs) implantation in the XXXⅡ. For further evaluation, we made a comparative review of the length of time until posterior capsulotomy and the survival rate in a unified observation period in eyes implanted with three-piece IOLs.


Saitama Red Cross Hospital


This retrospective study enrolled 8,971 eyes (male 4,607 eyes, female 4,364 eyes, mean age 72.2±10.8 years old) of patients who received cataract surgery implanted with 6.0 mm diameter three-piece acrylic IOLs from January 2002 through December 2007 at our Departments of Ophthalmology. In this study, Kaplan-Meier survival estimate was used equating Neodymium: YAG (Nd: YAG) with death, and was used to evaluate the survival rate.


The length of time until posterior capsulotomy and the survival rate during the 70-month observation period were MA60BM (Alcon) 41.3 months and 97.1%, YA60BB (HOYA) 30.4 months and 88.7%, YA60BBR (HOYA) 30.0 months and 88.8%, AN-6K (Kowa) 35.6 months and 91.9%. The survival rates of MA60AT and AN-6K were significantly higher than the other IOLs (p<0.001).


The result showed that the incidence of posterior capsulotomy was lower in eyes implanted with IOLs with sharp optic edge profile.
