If you have had eye trauma, injury, or corneal disease, it is possible to experience scarring to the corneal surface. This type of abnormality can block light from passing through the retina, leading to distorted eyesight or vision loss. It can even cause cloudiness, glare, irregular astigmatism, pain, irritation, and dry eyes. Phototherapeutic keratectomy, also known as PTK, is an innovative treatment that uses a laser to address corneal irregularities, including scar tissue. At Chu Vision Institute, we perform PTK using an excimer laser to deliver targeted heat energy to the cornea to help smooth surface abnormalities. If you have been experiencing blurry vision or pain associated with corneal scarring, we invite you to contact our office in Bloomington, MN at your earliest convenience. Board-certified ophthalmologist Dr. Ralph Chu and our skilled medical team have years of training and experience in performing advanced laser treatments, like PTK.
"Bare with my lengthy review but if you’re like me, I wanted to know what others true thoughts were and I scoured as many reviews as possible to make sure I was making the best decision for me and my eyes. I am SO, SO thankful for Dr. Chu and Dr. Heckman’s expertise and honesty. I decided it was time to get Lasik and went in for my consultation. From check-in to my latest follow up, everyone at the Chu Vision Institute was friendly, warm, and helpful. Due to some past corneal scarring, Dr. Chu recommended that I get Lasik on one eye and PRK (ASA) on the other. I was extremely nervous about PRK because of the slightly longer recovery time and I really just wanted to wake up and have 20/20 vision like my friends who have had Lasik. The day of my procedure, they made sure I had all my questions and concerns answered before they let me in to have my surgery. That was extremely comforting to me and Dr. Heckman explained why PRK was recommended over Lasik. Simply put, I wouldn’t have had a good outcome if Dr. Chu had performed Lasik on both eyes. Both procedures went well and Dr. Chu confirmed his right decision during the procedure which took all of maybe 10 minutes for both eyes. As instructed, I went home and rested and could literally see 20/20 the next day with my Lasik eye. The PRK eye takes a little longer to heal but can already see better! (I was worried my blurry eye would affect my vision, but it did not). Recovery has been great and will continue to get better in the next few weeks. Now my husband wants to get his eyes done. Chu Vision Institute has exceeded my expectations and I am very happy with my results!"- E.M. / Google / Oct 20, 2020
"I had cataracts removed from both eyes. Dr. Chu and his staff were wonderful to work with. From the exam to the surgical procedure and recovery, everyone was very professional and pleasant . I had a perfect outcome and would highly recommend the Chu vision Clinic."- B.S. / Google / Oct 02, 2020
"I’ve been going to Chu vision for about three years now and and I’ve had excellent service each and every time. They follow me yearly for my dry eye condition. They are extremely thorough and take the time to answer all my questions. Highly recommend them."- C.S. / Google / Jul 31, 2020
"Exceptional. I felt like family as soon as I walked through the front door. Staff was extremely knowledgeable and friendly and my LASIK procedure went flawlessly. Like most folks, I did extensive research for months before my consult (word of mouth and online) I highly recommend Chu Vision for your procedure."- C.M. / Google / Mar 19, 2020
"I want to thank everyone at Chu Vision for the remarkable care we received recently. The clinic has an immaculate protocol to prevent Covid exposure for all of its patients. One might think that all the masks would prevent a warm, caring environment but not at Chu Vision! To a person, everyone was warm and welcoming. Dr. Chu was terrific and extremely thorough. The clinic was able to assess my husband’s acute vision change using a remarkable variety of tests and tools. What would have taken weeks at another clinic took only hours at Chu Vision. We won’t ever go anywhere else. Thank you so very much!"- K.D. / Yelp / Jul 13, 2020
Best Candidates for PTK
You may be a candidate for PTK if you have experienced distorted or impaired eyesight, clouding of vision, dry eyes, pain, or other symptoms of corneal disease or injury. Patients who receive this laser-assisted procedure usually have superficial or moderate corneal scarring or abnormalities. If you have very deep scars or extremely thin corneas, this treatment may not be appropriate. To determine if you qualify, Dr. Chu will perform a comprehensive eye exam. This will allow him to design a customized treatment plan to address your specific condition.
PTK Procedure Technique
PTK is done as a quick outpatient procedure, lasting about 10 – 20 minutes. The PTK procedure process is similar to LASIK or PRK, but the main difference is that PTK is not used to correct a refractive error. To begin your treatment, your eyes will be numbed with special anesthetic drops to keep you comfortable the entire time, and you may also be given a mild sedative. Dr. Chu will position a device over the treated eyes to prevent movement. Then, he will utilize the cutting-edge excimer laser to deliver focused beams of light, selectively removing only the scarred corneal tissue while preserving the healthy surrounding tissue.
Follow-Up after PTK
After your treatment, a bandage contact lens will be placed over your treated eyes to provide comfort and aid in the recovery process. A nurse of the Chu Vision Institute team will send you home with any important follow-up instructions, such as how often to administer prescribed eye drops. In addition, you may need to attend a few follow-up visits after your PTK procedure to monitor your recovery and improving eye health. Many patients report experiencing better vision within about a day of their PTK procedure with continued improvements over time. Since PTK is not a refractive vision correction procedure, you may need to continue wearing eyeglasses or contacts to sharpen your eyesight.
Improved Vision with PTK
If you have scarred or irregular corneal tissue, it can result in impaired or blurry vision. However, these issues can be addressed to boost your sight and eye health. Chu Vision Institute provides PTK, a newer, laser-assisted method to effectively treat scarring of the cornea. If you'd like to find out more about PTK and whether it's a good option to treat your corneal scarring, contact our team in Bloomington, MN to book a comprehensive eye exam with Dr. Chu.
