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.
"Today after years of waiting to get LASIK I took the leap. Terrified as I was, all of the wonderful staff was amazing and kind. Dr. Chu talked me through the whole procedure, which is honestly an outstanding experience. I could not recommend Chu Vision Institute any higher! Perfect 10 :)"- M.B. / Yelp / May 04, 2021
"I came in for a Lasik consultation and Chu Vision is a well-oiled machine! Very organized and have the process of the exam and consultation down to a T. Everyone I encountered was very friendly! From the young man who checked me in at my vehicle, the exam and all the way to the end when I met with Amy Ray about scheduling and financing for Lasik. Love it and can't wait to put my eyes in your hands and get Lasik (spoiler...I'm an ideal candidate and will for sure be going to Chu Vision Institute)"- A.S. / Office Visit / Jul 14, 2021
"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 felt anxious at the pre op screening visit because I didn't understand how long the measuring process would take. Did I not ask enough questions? Did I not understand the explanations of the procedure? I'm not sure. But once I voiced my concern everything was explained to my complete understanding. The facility met or exceeded all the COVID protocols. It was close to home -- easy to access and had free parking. Dr. Chu was approachable and caring. Dr. Heckman was patient, caring and concerned about me as well as making sure Dr. Chu received the specs he needed to perform perfect surgery. THANK YOU!!!!"- N.C. / Office Visit / Jun 24, 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
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.
