53 yr old woman with scarring of the rt cornea has significant corneal thinning with a high risk of perforation and underwent reconstruction of the ocular surface. the eye is incised and an operating microscope is used with sponges and forceps to debride necrotic corneal epithelium. preserved human amniotic membrane is first removed from the storage medium and transplanted by trimming the membrane to fit the thinning area of the cornea and sutured. this process was repeated three times until the area of thinning is flushed with surrounding normal thickness cornea. all of the knots are buried and a bandage contact lens is placed with topical antibiotic steroid ointment
