Posterior Capsular Opacification
Some people can develop a posterior capsular opacification (PCO, also called an after-cataract). The posterior capsular cells undergo hyperplasia and cellular migration, showing up as a thickening and clouding of the posterior lens capsule (which is left behind when the cataract was removed, for placement of the IOL). This may compromise visual acuity and the ophthalmologist uses a Yag laser to safely and painlessly make small holes in the posterior lens capsule. It is an outpatient procedure.
