Posterior Capsule Opacifcation

Posterior Capsule Opacifcation (PCO) or After Cataract PCO is one of the inherent complications of modern cataract surgery. 

The posterior capsule is the part of the original cataractous lens, which acts as the support for the IOL. 

The posterior capsule may opacify over time and this is referred to as after cataract. 

Fortunately this is amenable to a simple treatment by means of a laser, a procedure called Nd:YAG laser posterior capsulotomy. 

Factors influencing PCO include: 

• Age of the person; the younger the patient, the more chances of PCO 

• History of intraocular inflammations like uveitis increases the chances of PCO 

• IOL; acrylic hydrophobic IOLs have been found to decrease the chance of PCO formation, as compared to PMMA IOLs
