Posterior chamber intraocular lens (IOL) implantation is a procedure used to implant an IOL into the posterior chamber of the eye, typically during cataract surgery. The posterior chamber is located behind the iris and in front of the retina, where the IOL is positioned after the cataract is removed.

This procedure is crucial for restoring clear vision after cataract removal, as the IOL takes the place of the natural lens that has become clouded. Posterior chamber IOLs are designed to mimic the natural lens and provide excellent visual outcomes.

This procedure is widely used and highly effective for patients undergoing cataract surgery, offering significant improvements in vision and reducing the need for glasses or contact lenses.
