The compassionate team at Chu Vision Institute is dedicated to using the most innovative technologies and treatments available to address glaucoma. If you have glaucoma, we may be able to limit damage to your optic nerve to save your sight with a procedure known as endoscopic cyclophotocoagulation (ECP). This minimally invasive treatment uses a gentle beam of laser light to decrease the amount of fluid produced in your eye as a means of lowering your intraocular pressure. As such, the ECP treatment is designed to limit or slow future damage to your vision.
Using this advanced technique to treat glaucoma, board-certified ophthalmologist Dr. Ralph Chu has helped many patients become less reliant on prescription medications and eye drops. Dr. Chu and the skilled and experienced medical professionals at Chu Vision Institute are widely knowledgeable about ECP and other advanced treatments for glaucoma. Contact us in Bloomington, MN to schedule your eye examination, and find out more about whether ECP could help effectively manage the symptoms of glaucoma.
"Where to even begin. I had been eagerly anticipating laser vision correction for at least 5 years but life continued to get in the way. I finally was in a position to move forward and found Dr. Chu and his practice upon moving to MN. I honestly do not have the words to express how thoroughly satisfied I am and continue to be with the entire experience. From the initial evaluation to the expert guidance, seamless follow up appointments, excellent communication, wonderful and friendly staff, truly knowledgeable physicians and providers who take the time to answer your questions, I could not be more pleased. I had initially wanted to have SMILE performed but, through the counsel of Drs. Heckman and Chu, underwent ASA with phenomenal results (and the vision continues to sharpen daily which is such an amazing thing to experience). Dr. Chu was able to take my vision from 20/500 (mostly from extremely severe astigmatism with coincident myopia) to 20/20. Most importantly, I was seeing 20/30 in my right eye the day following surgery and 20/20 by the 3-day follow up. At the risk of making this review too lengthy, I have to pay my respect not only to Dr. Chu's practice but to all the individuals who work there. From Dr. Hassan to Dr. Hampton, surgical intake nurses and all the techs, they legitimately made me feel like family. More than that, the work performed at this facility is second to none. I have already referred several colleagues for vision correction at Chu Vision. To top it off, Dr. Chu is honestly a stand up guy with some pretty amazing extracurriculars :) To anyone I may have missed, THANK YOU! Genuinely changing lives for the better. TL;DR - If you care about your eyes and want high-quality, complete care, look no further than Chu Vision. You will not be disappointed."- N.A. / Google / Aug 04, 2022
"I’m absolutely astounded at how instantly my vision was improved! I’ve gone from needing glasses for everything to having 20/20 vision again! I’m rather hesitant when it comes to needing anything medical. And now I want to tell everyone how incredible Dr Chu and his team are. From the folks helping to check you in to the kind and caring support on each and every visit, this has been my best experience EVER! Thank you to Nic, Asha and the research team, to all the Drs and the surgical team and to Dr Chu for believing in making a difference For ALL your eye needs, big or small, there is only one place you want to be. Chu Vision institute. Best decision I have made."- S.K. / Google / Sep 09, 2022
"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
"Dr. Chu did a wonderful job with my SMILE procedure, taking my -5.75 and -6 prescriptions to 20/20. My results are amazing, yes... but I think that being as nervous as I was, the thing that really made this experience phenomenal was the care that Dr. Chu, Dr. Heckman, and the whole team provided. I appreciate that they took the time to talk to me about all of my concerns before I scheduled my procedure - have really dialed in the actual day of your appointment so it's smooth and efficient and you always know what's going on and what to expect - and that they have continued to provide that level of care at every follow up appointment. I have always received such a warm welcome every time I have visited, and am grateful that they always find time to address any questions or concerns. PS - a special thank you to every technician I've been fortunate enough to meet at my appointments, you all provided such lovely, friendly conversation!"- N.M. / Google / Jun 28, 2022
"Can't speak highly enough about the results and experience I had with Dr. Chu and his team. After a Lasik procedure I have 20/20 vision. I was obviously a little concerned about having someone mess around with my eyeball with a laser... but the whole team at Chu Vision made me feel comfortable with the procedure and recovery and ensured I felt supported at every step. The procedure was a breeze - Dr. Chu has a great bedside manner and made me feel comfortable I was in good hands. Recovery was straightforward and it's now a full month that I've had great vision and not had to worry about corrective lenses. If you're considering refractive surgery with Chu, do it. My only regret is that I didn't do this sooner."- B.A. / Google / Aug 03, 2022
Am I a Candidate for ECP?
ECP is a more aggressive treatment so it is typically not used as the first line of defense against glaucoma. Depending on your specific case, Dr. Chu may recommend that you first try medications and other surgical procedures, such as selective laser trabeculoplasty (SLT). If you do not respond well with these types of initial treatments and you have high intraocular pressure and limited vision, we may determine that ECP is well suited for you. In addition, if you do not qualify for other glaucoma treatments, you may be a candidate for ECP. During your consultation at Chu Vision Institute, a full eye examination and a review of your health history will be performed.
ECP Procedure Technique
Dr. Chu performs ECP as an outpatient procedure at Chu Surgery Center, our accredited ambulatory surgery facility located adjacent to our Bloomington, MN office. ECP is sometimes, but not always, done in conjunction with cataract surgery. Before beginning the ECP, your eyes will be numbed with a local anesthetic. Dr. Chu will then insert a thin probe (about the thickness of a paper clip) into a tiny incision made in your eye. The probe has an attached video camera that allows him to see into the microscopic eye structures. Next, he will apply a precise, gentle laser energy beam to your eye's ciliary body, which is the structure of the eye that produces fluid. By using laser energy to cause scarring and inflammation of the ciliary epithelium, the amount of eye fluid produced is decreased. This treatment can also help decrease intraocular pressure. The tiny incision should heal quickly on its own so there is typically no need for stitches.
What to Expect After ECP
ECP itself takes about 15 minutes to perform, and you should not have a long recovery period afterward. Generally, you can expect to get right back to your routine. We may prescribe anti-inflammatory medications and antibiotic eye drops that you will need to use for the next several weeks. After ECP, many patients report heightened quality of life and increased freedom to continue in their regular activities. Although a cure for glaucoma does not presently exist, the team at Chu Vision Institute is committed to helping our patients manage their glaucoma symptoms with some of the most innovative technologies and treatments available today.
