DSAEK is short for Descemet’s membrane automated endothelial keratoplasty. In the normal eye, a layer of cells known as the endothelium lines the inner surface of the cornea on a membrane called Descemet’s membrane. These cells act as tiny pumps that precisely regulate the amount of fluid in the cornea to maintain its clarity.
Medical conditions such as Fuchs’ corneal dystrophy, cataract surgery and glaucoma can lead to a decreased number of these cells. This may result in swelling and clouding of the cornea, causing decreased vision and sometimes episodes of severe pain. Advances in surgical techniques have allowed us to remove only the diseased layer of the cornea and replace it with a thin layer of donor tissue containing healthy endothelial cells. We inject an air bubble to hold this graft in position for the first few days until the pumping new cells create enough suction to hold the graft in place unassisted. The patient needs to lie flat on his/her back for several days so that the air bubble in the eye pushes the donor corneal tissue against the back layer of the patient’s cornea.
Like a standard, full-thickness corneal transplant, this procedure is done on an outpatient basis. Visual recovery is more rapid after DSAEK, with stabilization of vision often occurring within three to four months after surgery. After DSAEK, vision remains more stable than it does with full-thickness corneal transplant. There is also a lower lifetime risk of graft rejection than in full-thickness transplantation.

"I've been essentially blind my whole life and recently decided to get elective eye surgery. I unfortunately did not qualify for Lasik, but did qualify for PRK. Dr. Rapoport was fantastic - she explained all my options in detail and was very diligent in giving me instructions pre/post operations - even when I asked twice/three times. She's always available to talk and super empathetic. I could not recommend a better eye surgeon!"
"Dr Rapoport is a skilled, knowledgeable, sincerely caring medical professional. I started seeing her a year ago and have since moved out of state. Regardless, it's a priority for me to continue under her good care. I feel confident in her abilities - and it is my eyesight afterall!"
"After seeing Dr. Rapaport for three months I have experienced the greatest improvement for my dry eye syndrome than I have in the past 15 years. Dr. Rapaport is very knowledgable and caring. I am very grateful to her and her staff, in particular to Amy, who has been incredibly helpful to me. Everyone here conducts themselves in a highly professional manner, and they also run a tight ship in terms of timeliness. I have been seen every time without waiting any more than 5 minutes, and this I appreciate a lot. I feel very fortunate to be a patient at this medical practice."
