Residual refractive error after multifocal IOL implantation can cause visual symptoms and decreased satisfaction. Piggyback IOL implantation is an option for correction of postoperative hyperopia after multifocal IOL implantation.. . R.D.Gopinath. Supervisor – Optical Sales. Introduction .

A cause of blindness and is conventionally treated with surgery. Vision loss occurs because . opacification. of the lens obstructs light from passing and being focused on the retina. 3. rd. leading cause of preventable blindness. CPOT, ABOC. Course Description. This lecture will focus on 20 common eye diseases. It will identify the disease, characteristics of the disease and the affects of the disease on the eye. The course will also discuss clinical presentations and testing associated with the disease.. Converging Lens = Convex. A . ray of light. is an extremely narrow beam of light..
