Phototherapeutic keratectomy, often shortened to PTK, is a laser-assisted treatment that is performed to reduce fogginess and various other corneal abnormalities, including scar tissue caused by trauma, injury, or cornea disease. These abnormalities often lead men and women to have cloudy vision, dry eyes, irregular astigmatism, and irritation, as well as pain. In situations when corneal irregularities reach beyond the outer superficial layer of the cornea, PTK is usually the go-to procedure offered at Wang Vision Institute. If you are experiencing discomfort or blurred vision due to corneal scarring, we encourage you to contact our Nashville, TN office as soon as possible. Our skilled team of ophthalmologists have years of experience and specialized training in performing advanced laser surgeries.
"Dr. Wang and his entire staff are professional, kind and informative. They went out of their way to reassure me, answer my questions and make me feel relaxed and comfortable. When I learned that I have steep corneas that would require PRK instead of Lasik I was disappointed and a bit panicked. PRK sounded more painful and would require a longer recovery time, neither of which I'd planned for. Erika, my coordinator, took the initiative to speak to Dr. Wang and have him review my test results. Dr. Wang determined that my corneas were only slightly steep and that I could indeed have 3D Lasik. I had the procedure in the late afternoon and was resting comfortably last night. I woke up this morning and could read the bedside clock. I am typing this without glasses which was IMPOSSIBLE this time yesterday. I feel like the world is much bigger today and I think Dr. Wang and his team. I'm so glad I made the decision to use Wang Vision for my corrective surgery and will refer friends and family as well."- C.M. / Yelp / May 20, 2015
"I am very pleased with the PRK surgery I had with Dr. Wang. His officers were very relaxing and everyone on his staff was young, friendly, professional, knowledgable and willing to help out in any way. Although Dr. Wang sees many patients each day I never felt like just another face in the crowd. While I was there I had many opportunities to speak to doctors on his team and ask questions without being rushed. You will et face time with Dr. Wang before and after the procedure, and he even called me personally later that day to check up on me. They provide outstanding customer service and the most experience and quality eye surgery, BUT do expect to be recruited to do some marketing for Dr. Wang at the end."- D.S. / Yelp / Oct 02, 2014
"I would like to give a special thanks to the on-call doctor at 11:30 PM 30/5/18 for addressing my questions politely (and coherently!) in the middle of the night. The customer service is phenomenal. They will address your every concern with patience, kindness, and depth. Dr. Ming Wang speaks with you personally at length during your evaluation, and then again right before/during surgery. All of the doctors/nurses are generous with information and guidance. To answer some questions I had had before surgery: The doctors will evaluate your eyes in the facility, and Dr. Wang will perform surgery the same day if you have followed pre-op instructions sent by the Patient Coordinator. After evaluation, your surgical options are presented to you alongside pricing.During refractive surgery (LASIK, PRK, & SMILE) you are safe from accidental eye movements, and my SMILE eye surgery was truly painless. Yes, it really does only take five minutes per eye!My recommendations stand proud with this center, and I'd once again like to thank the on-call doctor (11:30 PM CST, 30/5/18) for her outstanding patience!"- A. / Google / Nov 02, 2018
"Dr. Wang did a 3D Laser PTK w/ Amniotic Membrane Contact Lens (AMCL) procedure on my left eye today and the experience was GREAT! He is the only doctor in Tennessee doing it. I have been a patient of Dr. Wang's for 15+ years and wouldn't go anywhere else."- Anonymous / RateMDs / Apr 02, 2016
"Hi this is Casey McCasland here,I am writing this review for my good friend Dr. Ming Wang and all the staff at the Wang Vision 3D Cataract & Lasik Center. I have been seeing Dr. Wang for the past three years for my vision in one way or the other and have been very happy with everything they do. I was seeing other doctor’s about my vision, but they all said there was nothing to be done about it and I would have to live with it. But God showed me another way, I was looking on the internet and Dr. Wang’s web page just popped up and as I read about he not only was he a world renowned Doctor and Surgeon but for most he was a Christen. I called Dr. Wang’s office and got appointment right away and they was wonderful about everything. First it was the scaring on my cornea that he did the PTK surgery and cleared my vision. It was like night and day with my vision I was so happy. But then about a month ago my vision got cloudy overnight and the only person that I wanted to look at my eye was my friend Dr. Wang.In life there is trials that we all must go through and life had just thrown me another one. When I seen Dr. Wang he said that it was a cataract that was clouding my vision. But, he told me not to worry the good Lord and him would take care of me. He told me about the New 3D Cataract Laser Surgery that only he performs here would be what we would do. We schedule my surgery for the next week and helped me prepare for it.During the surgery Dr. Wang was having a hard time seeing the cataract due to the old scaring on my cornea. But, he and I prayed a prayer, then he removed the cataract with God’s help guiding his hands and the rest went great. I have been improving a little every day, the Lord blessed me when I found Dr. Wang. The night after the surgery my phone rang at 10 pm and when I answered it my friend Dr. Wang was on the other end, checking on how I was doing. That is another reason I would advise anyone to see Dr. Wang.SincerelyCasey McCaslandDecember 9, 2016"- Anonymous / RateMDs / Dec 09, 2016
This laser-assisted surgery is usually offered to individuals experiencing vision impairment, pain, dry eyes, cloudy vision, or other issues as a result of corneal trauma or disease. Ideal candidates for this treatment are patients whose corneal abnormalities reside below the epithelium in the lower-middle to middle layers of the cornea. However, men and women whose corneal issues exist in the epithelium could be better suited to receive a superficial keratectomy (or Super K) procedure. You may not be a great candidate for PTK if you have certain autoimmune or inflammatory disorders. In order to determine if this treatment is the best one for your needs, you will receive a comprehensive eye examination from one of the knowledgeable eye professionals on our staff.
What to Expect
Often performed using an excimer laser, PTK is a quick procedure that typically lasts around 10 – 20 minutes. The PTK surgical process is very similar to that of a LASIK or PRK procedure with the difference being that PTK is not a refractive correction. Before your treatment, your eyes will be numbed using special drops to ensure that the process is as comfortable as possible. One of our ophthalmologists will then place a device over the affected eye to prevent any movement. From there, we will utilize our state-of-the-art laser technology to accurately remove the unwanted corneal tissue. When your treatment is complete, you'll be given a bandage contact lens to wear to aid in the healing process and minimize any post-op discomfort.
Following your PTK treatment, a member of our team will schedule your future follow-up visits to our Nashville, TN office so we can assess your healing and vision improvement. Often, patients are given prescription eye drops to use for several weeks after surgery to prevent infection and dryness. A majority of men and women report having exceptionally better vision as early as one day after their PTK procedure with their results continuing to improve over the following days or weeks.
Your vision can become blurry if you have scar tissue or an irregular corneal surface affecting your eye. Thankfully, you don't have to live with these issues forever. Wang Vision Institute is proud to offer patients from Nashville, TN and beyond a diverse range of advanced treatments to improve their vision along with their overall eye health. To learn more about how PTK could be beneficial for you if you've experienced corneal scar tissue or other irregularities, contact our office and schedule a comprehensive eye examination with one of our skilled ophthalmologists.
