A Review of Posterior Capsule Opacification

Expectation of patients receiving modern day cataract surgery has become similar to refractive surgery. They expect almost perfect results, often emmetropia. Over the last few decades, PCO has been the most common visually disabling sequel of cataract surgery and has important medical, social and economic implications. Posterior capsule opacification (PCO) or after cataract refers to the opacity that develops in the posterior capsule after cataract surgery; a central PCO may affect light scatter (forward and backward), reduce contrast sensitivity, decreases visual acuity, thereby compromising working efficiency and productivity.
