Sulcus-fixated intraocular lens (IOL) placement is a procedure in which an IOL is implanted in the sulcus, the space between the iris and the natural lens capsule, of the eye. This procedure is typically performed when the natural lens is absent or damaged, such as in cases of traumatic cataracts, lens dislocation, or congenital lens abnormalities.

In this technique, the IOL is positioned within the sulcus to provide clear vision, especially in cases where the posterior capsule is not available for IOL fixation. The procedure can be performed with minimal complications and provides a stable, effective solution for patients with complex lens-related issues.

Sulcus-fixated IOL placement offers several advantages, including reducing the risk of complications like capsule rupture, and provides a reliable, long-term visual improvement after cataract surgery or lens trauma.
