Automated Lamellar Therapeutic Keratoplasty

blog

Automated Lamellar Therapeutic Keratoplasty (ALTK) is a surgical procedure which is used to remove stroma in the cornea in the eye. This is also used for intraoperative visibility during cataract surgery in patients who have hazy corneas. In this procedure, only the damaged epithelium and stroma in the cornea is removed, keeping the endothelium intact where just the superficial layers have been damaged. Lamellar keratoplasty is indicated if you are suffering from anterior to mid‐stromal corneal opacities and is based on microkeratome-assisted keratoplasty which leads to a smooth and sharp excision of the corneal stroma.
