Posterior Capsule Opacification and Nd:YAG Capsulotomy Rates after Implantation of Silicone,Hydrogel and Soft Acrylic Intraocular Lenses: A Two-year follow-up Study
To compare the posterior capsule opacification (PCO) and neodymium:YAG (Nd:YAG) laser posterior capsulotomy rates associated with three different posterior chamber foldable intraocular lenses (IOL).
Methods
We retrospectively evaluated the rates of PCO and Nd:YAG laser capsulotomy in 1150 eyes two years after standard phacoemulsification with a no-stitch 3.5mm clear corneal incision (CCI) and in-the-bag implantation of one of three types of IOL: 190 eyes received a one-piece round-edged hydrogel IOL (Hydroview H60M, Bausch & Lomb); 475 eyes a three-piece round-edged silicone IOL (AMO PhacoFlex SI-40NB, Allergan); 485 eyes a three-piece square-edged soft acrylic lens (AcrySof MA60MA, Alcon).
Results
The PCO and Nd:YAG laser capsulotomy rates were respectively 43.15% and 20.5% in the Hydroview H6OM group, 27.57% and 9.68% in the AMO PhacoFlex SI-4ONB group, 10.5% and 2.47% in the AcrySof MA6OMA group.
Conclusions
PCO and Nd:YAG laser capsulotomy rates were significantly higher in the Hydroview H6OM group and significantly lower with the AcrySof MA6OMA lenses, which combine a bioactive constitutive material with the square-edged optic design.
