What is a common complication of cataract surgery?

Posterior capsule opacification (PCO) is a well-known complication that can occur after cataract surgery. During the procedure, the cataractous lens is removed, and an artificial intraocular lens is typically implanted. The original lens capsule remains in the eye to hold the new lens in place. However, over time, the capsule can become cloudy due to cell proliferation, which leads to a decrease in vision similar to that caused by the original cataract.

PCO is the most common cause of decreased vision following cataract surgery, and it is treatable through a simple outpatient procedure known as YAG laser capsulotomy. This procedure precisely targets the cloudy capsule, creating an opening and restoring clear vision. The prevalence of PCO emphasizes its significance as a complication, making it very relevant in discussions about cataract surgery outcomes and patient care.

Other potential complications like glaucoma, corneal abrasion, and retinal detachment can occur in cataract surgery, but they are less common compared to PCO. Therefore, PCO stands out as the primary concern that practitioners monitor in the post-operative care of cataract surgery patients.
