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.
"I had LASIK at Chu Vision last week and couldn’t recommend them highly enough. They provided a great consultation and advised on the best procedure for my eyes. Every detail (large and small) was planned for, and the whole process was very smooth. Best investment I’ve ever made!"- J.M. / Google / Apr 26, 2021
"I had LASIK performed by Dr. Chu and the entire experience was wonderful. All of the staff members were extremely nice and helpful - from the check in person who coordinated my visit to the tech who explained what all of the tests were and why they were needed during my evaluation appointment. Dr. Chu personally has a web call with you a few days before your surgery to ensure you do not have any other questions and are still comfortable with moving forward. The day of the surgery, Dr. Chu checks in with you right before you enter the laser room, performs the surgery himself, and then follows up immediately after by looking at your eyes to ensure everything went well. Chu Institute isn't the cheapest LASIK option, but it is clear why they are viewed as a leader in this field throughout the nation. From the knowledge and professionalism of the staff, to the attention that is received from Dr. Chu himself, to the best and latest technology to ensure the optimal results for your vision, they are worth the little extra. I personally wouldn't want my procedure done through a Groupon on a 10 year old laser system - your eyes are worth more than that."- P.P. / Google / Mar 11, 2021
"I cannot say enough! I got LASIK through Chu Vision and everyone was informative and friendly throughout the entire process. They still answer every question with a smile! 11 out of 10 experience!"- C.F. / Facebook / Feb 11, 2021
"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’m so impressed with Chu Vision!! Everything inside is totally sanitized and they have a state of the art filtration system. I have never felt safer! It’s so clean, you could eat off the floor. The entire staff is incredible! Everyone is so friendly, welcoming and professional. I have been going to Chu Vision for the past 10 years and I will never go anywhere else. Thank you for your wonderful service!"- J.T. / Google / Dec 19, 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.
