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.
"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
"Dr. Chu changed my life!!! The procedure was so easy and fast! My eyes are feeling amazing not even 24hrs later. The staff was always extremely friendly and knowledgeable"- S.P. / Google / Jun 16, 2022
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.
