Posterior capsular polishing is a technique performed during cataract surgery to clean any residual lens material or opacities from the posterior capsule of the eye. This step is essential in preventing complications such as posterior capsule opacification (PCO), which can cause clouding of the vision after cataract surgery.

The surgeon uses specialized instruments to gently remove any remaining cortical material and polish the capsule, ensuring a clear visual axis for the intraocular lens (IOL). This procedure helps to improve the overall results of cataract surgery, offering clearer vision and preventing future issues.

Posterior capsular polishing is often a routine part of modern cataract surgery and is highly effective in reducing the risk of PCO.
