Abstract
Posterior capsular opacification is the most common complication after cataract surgery with intraocular lens implantation. Different strategies have been proposed to avoid PCO including 360° continuous sharp edges of the posterior IOL optics rim, haptics angulations, or surface modification of the optics. However, depending on the IOL material and surgical technique 20 to 60% of eyes require Nd:YAG laser capsulotomy in the first 2 years after cataract surgery. In this talk we would like to define a scattering model for the posterior lens capsule and perform raytracing through the pseudophakic eye with a scattering capsule to investigate the impact of biometric parameters on the scatter characteristics and contrast transfer of the eye.
