Correlation between intraocular lens design, material and posterior capsular opacification rate

ABSTRACT

To evaluate and to compare the rate of occurrence and degree of posterior capsular opacification [PCO] after small-incision cataract surgery and implantation of two different Intraocular lens [IOL] materials and designs over 6 months follow-up. Magrabi Eye and Ear Hospital, Jedda, KSA, New Dar Al-Shifa Hospital [NDASH], State of Kuwait, International Eye Hospital, Cairo, Egypt. 80 eyes were included in our study. All eyes underwent st and ardized phacoemulsification technique and were divided into 2 groups; Group [A] 40 eyes implanted with silicone IOL [PhacoFlex, round edged design, Allergan] and Group [B] 40 eyes implanted with acrylic IOL [Acrysof, sharp edged design, Alcon]. A st and ardized morphological mapping for evaluation of PCO was done 1, 3, and 6 months postoperatively. NdYAG capsulotomy rate was also reported. Acrysof group had lower PCO incidence than silicone group, [20% and 30% respectively]. The Nd YAG capsulotomy rate was 12.5% in Acrysof group and 22.5% in silicone group. Eyes implanted with acrylic lOLs had lesser PCO incidence and subsequently lesser Nd YAG capsulotomy incidence than those with silicone IOL
