Vision Correction Testimonials

William McCauleyFor my 65th birthday, I asked Dr. Harry Koster to replace the lenses in both my eyes with multifocal lenses. I had gotten to 4.0 strength reading glasses, and the world was a big blur to me. Dr. Koster and his staff are very smart and very friendly. The surgery takes 15 minutes or less and is completely painless. Four hours after the procedure, I could read without glasses, and I can now easily read the bottom line on the eye chart. My world is brighter, more colorful, and full of detail I haven’t seen in decades. Dr. Koster is so adept as a surgeon that the staff at both the office and the surgery speak of him in hushed tones as “The Hands.” This was a life-changing experience for me, truly a gift beyond price (and the price was very reasonable!).

Julia A.I can see clearly now without my glasses on! My life has changed so much in the little more than a year since I had the monovision/LASIK surgery. I never imagined that I would see as clearly as I do today.

I must admit I was quite apprehensive when I first went for a consultation. Yet you, along with your staff, were patient in explaining every detail to me and calming my fears. Quick, painless, and minimal recovery. Truly wonderful!

It did take me a couple of months to stop reaching for my glasses. But in just a few days I saw clearly and with no problems.

Everything is so much easier now without glasses.

Patient Reviews New York"I would definitely recommend Dr. Koster and the team for your PRK surgery. I had not heard of the PRK procedure when I came to Dr. Koster and was very apprehensive with many questions. Dr. Koster was understanding of my concerns and answered round after round of questions. During and after the surgery the team was very supportive of Dr. Koster giving his cell phone to call over the weekend with any concerns. My procedure was a success and I have already recommended a colleague to the practice"

Happy LASIK PatientI am extremely happy I chose to have LASIK with Dr. Harry Koster. I can honestly say that the procedure changed my life -- no more waking up unable to read the alarm clock, no more contact lens infections, no more worrying about losing a lens while swimming.

I would recommend Dr. Koster to anyone considering LASIK.

Lidia Rekas LASIKBeing a health-conscious athlete, I take a proactive and informed approach to my well-being. After fifteen years of glasses, contacts and sports goggles, I got LASIK from Dr. Koster and my life immediately became easier. What makes Dr. Koster an exceptional doctor is his distinguished expertise, passion for improving my vision, patience in answering my thousand questions and making me feel I'm in very capable hands.

Getting LASIK from Dr. Koster was among the best and easiest decisions I've made in life. Whether I'm competing in ironman triathlons, climbing mountains or working, I know my vision is well cared for by Dr. Koster and his team.

After wearing glasses and then contact lenses for nearly all of my life, I am finally free! Thanks to Dr. Koster and the staff of the NY Laser Group, I am now able to wake up every morning without having to first search for my glasses. I can now go swimming without having to worry about losing a contact. Ah, it’s the little things in life.


I was initially reluctant to have any type of laser vision correction procedure performed on me, but my reluctance was simply based on my lack of knowledge about the procedures. During my free consultation, Dr. Koster spent a significant amount of time with me answering all of my questions and explaining the PRK procedure to me in great detail. After our discussion, I was convinced that PRK was for me. Needless to say, it always helps to know that the procedure is being performed by a Harvard medically trained physician with more than 15000 procedures under his belt.


Another unexpected pleasant surprise about my experience with Dr. Koster and the staff of the NY Laser Group was the extent to which they made themselves available to me for any follow-up questions or concerns after the procedure. My procedure was performed on a Friday morning, and Dr. Koster provided me with his cell number to reach him over the weekend if necessary. Additionally, one of the staff members called me that Saturday morning (on her day off) to see how I was doing.

It’s been two months now since I’ve had the PRK procedure performed on me, and I am seeing 20/20 without any issues.

Based on my experience with the NY Laser group, I would highly recommend Dr. Koster and team to anyone who is considering having laser vision correction.

Thank you for giving me the opportunity to express my feelings on the fine work Dr. Harry Koster does with regard to eye surgery. It was May and June of 2006 when Dr. Harry Koster performed my implant surgery in my eyes. I was hesitant at first, but then I finally agreed to do the surgery. Dr. Koster is a miracle worker! I have 20/20 vision now and haven't had any residuals in the four years since the surgery. It's so amazing. If I didn't know I had the surgical implants, I would never believe that such a surgery is possible! Not only is Dr. Koster a very skilled surgeon but he is also a very caring and gentleman. I can't say enough about him and his practice. 

Best regards,

I had two surgeries done on my eyes to correct nearsightedness: a LASIK surgery on the left eye and an ICL lens implant on the right eye. Both surgeries were very successful and I recovered quickly experiencing almost no discomfort during the recovery period. 
A few hours after the ICL lens implant, I noticed a significant improvement in my vision but the biggest difference was the next morning when I woke up seeing everything very clearly (clearer than with contact lenses or glasses that I used to wear prior to surgery). Now, I have 20/20 vision, which may slightly fluctuate, but stays stable most of the time.
The LASIK surgery on my left eye also significantly improved my vision and I could see the change already a few hours after the surgery. The procedure I underwent was done without the so-called “flap”, and it takes a little bit longer for the eye to heal, as the laser was used right on the surface of my eye. Therefore, a few months after the surgery my vision is still a bit blurry and fuzzy; however, I can see clearly every day as the eye heals.
Overall, I am very satisfied with the outcome of both procedures as my vision is even better than when I used to wear glasses or contact lenses…and I don’t have to wear them anymore. It was the best decision I have ever made with regard to my health. The world looks better now!

Nicole LuciaAlternating between glasses and contacts had always been part of my life. I’ve always had thoughts in the back of my head of undergoing Lasik to improve my vision. I decided it was time to investigate surgical correction, so I met with Dr. Koster for a consultation. He and his staff were extremely thorough with their eye exam and took the time to answer all my questions.

The day of the surgery Dr. Koster talked me through the procedure and made me feel at ease. The procedure was painless and the results were almost immediate. The very next day I woke up with 20/20 vision! I was able to function and resume my normal activities.  It’s been wonderful to no longer worry about misplacing my glasses, fighting to get my contacts in, or (worst of all) rubbing my eye and my contact lens falling out! I highly recommend the surgery and could not be happier!

Dr. Koster,

I placed complete confidence in you when I decided to have you perform my cataract surgery. I am very pleased with the results. You performed this surgery with such skill and precision my cornea transplant was not affected, and in the process, my astigmatism was corrected. Thank you, Dr. Koster.

Nicole LunnMy experience with the physicians and staff at NY Laser Group has been top-notch.  After 20 years with glasses and 15 years with contact lenses, I can hardly believe I can now see 20/20 without assistance.  My laser PRK procedure, performed by Dr. Koster, was a stressful life event that I approached with some degree of nervousness and trepidation. I am so grateful for the compassion and reassurance of Dr. Koster and his staff before, during, and after my surgery. The comfort of knowing I was receiving expert care during such a delicate procedure was indispensable. Every day that I wake up able to see the time on my alarm clock clearly, I am still in disbelief. I could not be more satisfied with my choice to have undergone refractive surgery with Dr. Koster and I would highly recommend NY LaserGroup to any of my friends, family, or colleagues.

Dear Dr. Koster,                                     

The best thing that happened to me in 2016 was my referral from Dr. Maddona at the University Eye Center to your office. In late May and early June, you implanted in me a multifocal lens in either eye and inserted stents to control my intraocular pressure. Thanks to your skills and your kindness, I now at, the age of 79, see with the clarity I enjoyed when I was 35. No reading glasses, no magnifying glasses, no driving glasses. This is a miracle and you are a miracle worker. From the bottom of my heart, I thank you for what you have done for me!

Yours warmly, John Githens


 "I had contemplated Lasik surgery for a number of years. I waited to find a good recommendation which I received from the NY Vision Group. From my first inquiry to the moment I read 20/15 a few minutes after the procedure, I've been completely blown away by the experience and result. Professional. Friendly. Charming and most importantly, absolute quality. This was of paramount importance to me. Why on earth would anyone look for this procedure to completed by anyone cutting corners or shortchanging the highest quality. I was very happy to hear about the fact that there is not one corner cut. Every aspect of the experience is of the highest quality possible and available. And that has clearly given me the highest possible result. On my third week check up I even managed to read 5 of 7 letters at 20/10. I don't think I ever read 20/10 before and if I did I certainly didn't appreciate it. Even the actual procedure was more like a virtual reality experience that had absolutely no discomfort what so ever. I couldn't be happier with the result now and only wonder why I waited so long. Oh yeah - I had to find the right place to trust. And I did. My endless thanks to Dr. Koster and his team. I'm literally thrilled - I'd forgotten the freedom that great eyesight provides and I'm so grateful to have it at again. "

Until I was treated by Dr. Koster, I was totally dependent on eyeglasses. My vision was very poor and progressively getting worse each year. Even with glasses I had blurred vision and suffered from dry and gritty eyes every day. I thought there was no help. Dr. Koster changed all that and gave me back my eyesight. The world is now a brighter and more colorful place.
I was diagnosed with Saltzman nodular corneal degeneration in both eyes. Dr. Koster performed a superficial keratectomy on both eyes to remove the scar tissue caused by Saltzman. I then had intraocular lens implants in both eyes one of which is a blended lense. It has been four months since the completion of my surgeries and I am still amazed that I can see without glasses. I had no idea this was even possible.
From the minute I met him, I knew I was in excellent hands. I was nervous at the thought of eye surgery but Dr. Koster insured me that he would take the best care of my eyes and he did. His calm demeanor put me at ease and calmed my fears. During my visits with Dr. Koster, he treated me like a friend and made this entire experience a pleasant one. His examinations are thorough and he takes the time to explain in a clear and understanding manner. I was prepared for each surgery and was not nervous or fearful in the least. I had complete trust in Dr. Koster. After surgery, he took the time out of his busy day to call and see how I was doing. He was as happy as I was with the outcome. That meant so much to me and showed how caring he is.
Dr. Koster is an excellent eye surgeon and I consider myself lucky to have found him. I am truly appreciative and grateful for the care that he gave me. Dr. Koster is not only an excellent eye surgeon but a kind and caring person. I can not say enough about him and his practice.
I would also like to thank Dr. Koster’s staff for always being so helpful.
