It was great service

During the procedure, my surgeon talked me through each step, which was very reassuring. This reflected his whole approach—from explaining what vision to expect realistically for my particular issue to personally checking my eyes after the surgery on both was done. It was great service. The communication was great throughout and everything was made clear; the experience was incredibly smooth. I appreciate that the clinic has stayed in touch as I begin my recovery.

It was a very good experience for us and we are grateful for the treatment provided

It was a very good experience for us, and I will use this service in the future if necessary. All the answers to my questions were given. Everything is very organized. They have their own counter at the airport, where they arranged a transfer for us and brought us comfortably to the hotel. We were accompanied everywhere. The price of the service was as agreed in advance. There were no additional payments. I only spent money on my husband's eye drops at the pharmacy, but they're sold at affordable prices. The hospital is very modern, it's a large complex, there's a university nearby. The hospital has a special department for dealing with foreign clients. We didn't run, we weren't looking for anything, Mustafa was with us all the time and made arrangements for everything himself. There were a few days between the diagnosis and surgery, and we managed to book several tours of Istanbul. It helped us relieve the tension of worrying about the surgery. My husband has an agimatism, he got the best lenses in the world that exist right now. These lenses were made specifically for the parameters of his eye. It's been less than a week since the surgery, but my husband says he can see some things even better than he had with glasses before. The rehabilitation is not over yet, he has to drip eye drops on schedule for a month, take care of eyes, and don't lift heavy things and rub eyes. The doctors have done their job, now a lot depends on how clearly my husband adheres to the doctor's recommendations. It was a very good experience for us and we are grateful for the treatment provided.

My surgeon's thoroughness was notable

My surgeon's thoroughness was notable. He tested my eyes extensively before we confirmed the final plan for my cataract surgery on both eyes, which were treated a few days apart. The clinic has stayed in touch. My recovery is progressing about as expected. The only extra cost was for eye drops. If you need sedation, I would advise bringing your own. PS. Please bring your sun glasses too.

What I particularly valued was the continuity of care from the surgeon

If you're researching laser eye surgery, the small details of the process are what matter. I opted for the TransPRK procedure. The clinic's protocol involved operating on each of my eyes on separate days, which I viewed as a careful and methodical approach to the surgery. What I particularly valued was the continuity of care from the surgeon. They personally handled every single one of my checkups, from the first consultation to all the follow-up appointments, ensuring I was seeing the same expert throughout. That was important. As I'm still in the early recovery phase, having a clear aftercare guide has been essential, and the one provided was very comprehensive. From a practical standpoint, every aspect of the service, including the surgeon, the support staff, and the clinic environment, was well-executed and professional.

I am very impressed with the quality and standard of the whole process

Communication was great. I was picked up from the hotel, transfered to the hospital, and accompanied by Adam (translator) through the journey. He knew exactly the intake process and what they would want. He was well organized and very friendly. The consultant spoke English and was very calm, and professional. I had femto iLasik which was without complication. Pre-op my prescription was -7. Day 0 post op, I could still see but with blurry vision. Day 1 post op, my vision is now 20/20. But eyes feel gritty but hopefully will ease in a few days. I am very impressed with the quality and standard of the whole process. I would highly recommend Turkey for medical tourism. It's affordable and a beautiful clean city to visit as well. Stupendous experience.
