Corneal stromal implants are used to treat conditions like keratoconus, a progressive disorder in which the cornea thins and bulges, causing distorted vision. The procedure involves inserting a synthetic material, often made of biocompatible plastic or other materials, into the corneal stroma (the middle layer of the cornea) to help reshape the cornea and improve its strength.

This minimally invasive technique can stabilize the cornea, improve vision, and reduce the need for corneal transplants in patients with moderate keratoconus. The implant can also slow the progression of the condition and restore normal corneal curvature.

Corneal stromal implants provide an effective alternative for managing keratoconus, offering patients improved vision and delaying the need for more invasive surgeries.
