Posterior Capsular Thickening - Grosvenor Eye Clinic

What is Posterior Capsular Opacification (PCO)?

Posterior Capsular Thickening, often referred to as “posterior capsule opacification (PCO)” or “secondary cataract,” is a condition that can occur after cataract surgery. During cataract surgery, the cloudy lens (cataract) is removed, and an artificial intraocular lens (IOL) is placed inside a remaining clear sack called the lens capsule. Over time, the posterior (back) part of this capsule can become thickened and cloudy, leading to PCO.

What are the Symptoms

Blurred Vision: Similar to the initial cataract symptoms, one's vision can become blurry or less clear.
Glare: There can be increased sensitivity to light, leading to difficulties, especially during nighttime or in bright conditions.
Reduced Visual Acuity: Despite having clear vision post cataract surgery, one might experience a decline in vision quality over time.
Vision Distortions: Instances of double vision, halos, or ghost images might be experienced.

Causes of Posterior Capsular Thickening (PCT)

Cellular Regrowth: Residual lens epithelial cells, left behind after cataract surgery, can start to proliferate and migrate to the posterior part of the capsule, causing it to become cloudy.
Lens Fiber Regrowth: Lens fibers can regrow over the posterior capsule, making it opaque.
Incomplete Removal: If not all the cloudy lens material is removed during cataract surgery, the remaining cells can cause the capsule to thicken.

The emergence of Posterior Capsular Opacification (PCO) often happens subtly, potentially taking root over extended periods or emerging within a matter of months. As PCO develops, individuals may find challenges in tasks such as driving under low-light conditions, discerning fine details in text, and finding that even with the assistance of glasses or contact lenses, visual clarity remains elusive.

PCT Treatment

YAG Laser capsulotomy

YAG Laser Capsulotomy is a swift, non-invasive procedure performed by MR Trikha to treat Posterior Capsular Opacification (PCO), a condition that can develop after cataract surgery. Using precise laser pulses, MR Trikha creates a small opening in the clouded capsule, restoring clear vision for the patient. This outpatient procedure offers a quick and effective solution to combat visual disturbances caused by PCO.
