Keratoplasty, specifically endothelial keratoplasty, is a surgical procedure aimed at replacing the damaged endothelial layer of the cornea, which is crucial for maintaining corneal clarity and overall eye health. This procedure is particularly beneficial for patients suffering from endothelial dysfunction, a condition that can lead to corneal swelling and vision impairment. The two primary techniques employed in endothelial keratoplasty are deep lamellar endothelial keratoplasty (DLEK) and Descemet's stripping endothelial keratoplasty (DSEK). DLEK involves the dissection and removal of the posterior corneal stroma, while DSEK focuses on stripping the Descemet's membrane to facilitate the transplantation of a donor lenticule. Both techniques require precise surgical maneuvers, including the creation of a scleral tunnel and the careful placement of the donor tissue into the anterior chamber of the eye. The use of viscoelastic substances, such as Healon, is critical during the procedure to maintain the anterior chamber's structure and facilitate the smooth insertion of the donor lenticule. Overall, endothelial keratoplasty is a vital intervention for restoring vision in patients with specific corneal pathologies, ensuring that the cornea remains clear and functional.
