What Is DSEK?
The health of the inner corneal layers is essential to your vision and eye health because the cornea helps focus light into your eye so you can see clearly. If your cornea becomes swollen or cloudy from corneal endothelial disease, you may need a corneal transplant to improve the vitality of your cornea. Thanks to newer advancements in technology, a full-thickness corneal transplant may not be needed for patients with diseased or damaged corneas. A partial-thickness corneal transplant, known as Descemet's stripping endothelial keratoplasty (DSEK), removes only the inner corneal layer (endothelium). That section is replaced with a thin sample of donor tissue to provide better vision. This is unlike a full-thickness transplant, which involves removing and replacing the entire cornea. Board-certified ophthalmologist Dr. Ralph Chu utilizes cutting-edge technology to perform DSEK surgeries for patients with various types of severe corneal disease or injury.

"This staff is absolutely amazing!!! They talk to you as a human and take the time to explain what they are going to do. They spend time answering questions and concerns. Dr. Chu and his team…I honestly couldn’t have asked for more. They genuinely care, and you can hear it in their voices. I was nervous, and as an adult male that can be….belittling…but they were amazing! They actually pumped up my confidence. I will never go anywhere else for my eyes. I plan on scheduling all my appointments with them. Give them a chance, they will not disappoint. I heard it in the waiting room, everyone was happy and appreciative. Thank you all for making my life better!"- B.J. / Google / Jun 10, 2022
"Lasik was not something that i ever thought would be an option as it never was for my astigmatism and far sighted vision issues. New technology made something i never thought possible a possibility. This was the easiest thing ever. From what i expected was that it was suppose to be a slow progression and will continue to improve over next 6 weeks. I am already mind blown by how it has gone and how well I see. No glasses and I see better than I ever did with glasses...lol. Best Doctor, team, and experience. I HIGHLY Recommend everyone using Chu Vision Institute for all ete care needs. You will not regret it. Thank you!"- J.D. / Google / Mar 31, 2022
"From the day I walked in for my consult to the day after surgery and my first post-op, Chu Vision provided nothing short of a stellar experience. After 30 years of my life spent wearing glasses and 27 years with contacts, my vision stabilized and I was referred to Chu Vision. LASIK has been something I've wanted for many years but will be the first to admit my gut was wrenching with anxiety the entire month leading to the procedure after weighing the pros and cons of eye surgery. Browsing the internet and learning about side effects: glares, halos, starbursts...didn't exactly help my anxiety. Don't get me wrong, without glasses or contacts, I could barely make out the big E in the eye doctor's office. If anyone broke into my house, if a contact fell out while swimming, if something happened to my contacts/glasses on vacation...I'd be screwed. I wanted to be free. My 1:1 prior to surgery with Dr. Chu definitely put me at ease. The entire staff at Chu Vision is extraordinary...something you wish for at any service-related business. They calmed my nerves, walked through every step, answered all my questions, advised me how to prepare and what to truly expect afterward. The day of surgery was quick and absolutely painless...no pain at all, and my entire time at the office was 45 minutes. The actual procedure was less than 10 minutes. Dr. Chu provided an amazing surgery and turned my -6.75 prescription WITH ASTIGMATISM to 0!!!! The day after surgery for my post-op, I could easily see 20/20, and I know they don't guarantee better than 20/20, but I was able to see 20/15 the day after surgery, with my own eyes...truly amazing!!!! TO THIS DAY I CATCH MYSELF IN AMAZEMENT BECAUSE I KNOW WHAT IT WAS LIKE TO NOT HAVE THIS VISION WITH MY OWN EYES. I'm now 4.5 weeks out from when I had surgery and the post-op procedures and drops are cake. I have not had ANY glares, halos, starbursts, nothing. I can see clearly at night and during the day. "Whereas once I was blind, now I see." Thank you so much Dr. Chu, your team, and the experience you have built. I can't put into words how you have changed my life. Thank you so much."- C.K. / Google / Jan 20, 2022
"I had cataract surgery and before surgery had cloudy vision and a great deal of difficulty with night driving-halos, difficulty seeing lines on the roads especially on wet roads. I got the light adjusted lenses. It took a few weeks of adjustments but now I can see clearly to read and drive without glasses and the best part is I can drive at night and I don’t have the haloes around lights with oncoming traffic and I can see the road and lines even in the rain!! No glasses needed!!! I wear regular sunglasses in the sun but no prescriptions. Thanks Dr. Chu!!! Your staff was amazing-each person was polite and friendly and professional!"- L.F. / Google / Jun 04, 2022

Who Needs DSEK?
The most common candidates for DSEK are individuals with Fuchs' dystrophy, an inherited condition that causes blurry or cloudy vision. Other symptoms include pain around the eye, as well as glare or halos around lights. DSEK is also a recommended treatment for some patients with other eye diseases or injuries. Regardless of your specific corneal issue, Dr. Chu and the caring team at Chu Vision Institute will provide a full eye evaluation and any needed testing to determine your personalized course of treatment to improve your eye health.
Surgical technique for DSEK
DSEK is an outpatient procedure lasting about 45 – 60 minutes, performed at Chu Vision Institute. First, numbing drops will be used to anesthetize your eyes to help keep you comfortable, and light sedation may be administered. Then, Dr. Chu will make a small incision at the edge of the cornea to allow him to retrieve and remove the damaged or injured section. Next, he will utilize a special instrument to insert a very thin sample of healthy donor tissue into the same tiny opening. A gas or air bubble will be used to secure the tissue into place. The incision should heal up on its own so stitches are typically not needed. Afterward, a bandage contact lens may be placed over your eye.
What to Expect after DSEK
For patients who qualify, DSEK can be an ideal option to treat corneal disease because it has a lower rejection risk and shorter recovery time than a traditional full-thickness transplant. After your procedure, our team will give you detailed post-operation guidelines for at-home care, such as keeping your head facing up for the next couple of days. It is critical to follow these instructions and attend any follow-up appointments at Chu Vision Institute to ensure proper healing and check for potential complications. With DSEK, you should begin to notice improved vision after the first two months, and you can expect to achieve 20/40 vision within about 5 – 6 months.
A Clear Choice for Corneal Surgery
DSEK can effectively treat corneal swelling and blurred vision in patients with corneal damage or disease. With this innovative method for a partial-thickness corneal transplant, damaged cells are removed and replaced with a healthy donor graft.
