Abstract:
The purpose of this study was to evaluate the in situ relationship of ThinOptX intraocular lens (IOL) in a cadaveric donor eye with posterior capsular opacification (PCO), following report of high PCO rates with this IOL. A cadaveric donor eye implanted with ThinOptX IOL and received at our eye bank was fixed in 10% formalin after retrieval of corneoscleral button. The globe was sectioned at equator and evaluated from the posterior (Miyake-Apple) view. Complete iridectomy was performed and IOL evaluated from the anterior (surgeon's) view. The IOL was well centered in the bag. A thick (Grade 4) Sommering ring was seen with centripetal extension across the IOL edge margin. The anterior capsule showed fibrosis and distortion of the capsulorrhexis margin. It seems from our findings that in some cases, the edge of the ThinOptX IOL may not provide an adequate barrier to epithelial cell migration and PCO formation. This can have clinical implications which need evaluation in large clinical and histopathological studies.
