Purpose: To determine the effect of intraocular lens' (IOL) haptic number on posterior capsule opacification (PCO). Methods: In this retrospective study, between October 2001 and December 2002, inthebag implantations of IOL were performed after standard phacoemulsification surgery in 169 eyes of 127 senile cataract patients and they received standardized medication. 62 eyes received AcrySof MA60BM hydrophobic acrylic IOL with 2 haptics (group1), 70 eyes received DR.SCHMIDT MCTE hydrophilic acrylic IOL with 4 haptics (group2) and 37 eyes received OcuflexANU6 hydrophilic acrylic IOL with 2 haptics (group3). The patients were examined at 1st, 3rd, 6th, 12th months after implantation and in their last visit. PCO is demonstrated on the basis of ³2 line decrease in best corrected visual acuity (BCVA) in Snellens' chart, objective appearance of PCO on retroillumination of posterior capsule under biomicroscopy, and the need of Nd: YAG laser capsulotomy. Results: 4 eyes of 1st group, 13 eyes of 2nd group and 10 eyes of the 3rd group showed ³2 line decrease in BCVA. In the biomicroscopic examination there were PCOs in 3 eyes of 1st group, 11 eyes of 2nd and 17 eyes of the 3rd group. 2 eyes in 1st group, 7 eyes in 2nd group and 8 eyes in 3rd group required Nd: YAG laser capsulotomy in their follow-up visits. Conclusions: DR.SCHMIDT MCTE cause less PCO than OcuflexANU6 but more PCO than AcrySof MA60BM. DR.SCHMIDT MCTE shows similar results by means of Nd: YAG laser capsulotomy requirement with AcrySof MA60BM. So it's a good choice for phacoemulsification surgery.
