This is an amazing place with amazing doctors. My daughter is so grateful for all of them and their hard work. Dr. Steven Greenstein is a very good doctor. My daughter Tiffany Ramos now has 20/20 vision thank to God and Dr. Greenstein. I really recommend this place.


I could not be happier with The Cornea & Laser Eye Institute and would, and have, recommended them to everyone!!! From the great staff at the front desk that greeted me with a smile and knew my name the second I walked in, to the nurses, doctors and Office Manager always made me feel comfortable with my procedure. Jen at the front desk was super friendly and answered my 100 questions, Helena and Karen also at the front desk both helped with scheduling me and answering my questions. Dr. Greenstein did an amazing job and was super patient with me and personally called me on my cell after my procedure. Stacey Lazar is super nice and answered my other 100 questions and explained everything to me step by step. Amazing facility and staff!!


I have complicated corneas. Glasses can't correct my vision enough for driving; my dry eyes and irregular scleral surface make contact lenses problematic. When the doctors I had been using said there was nothing left that they could do for me, one of them referred me to CLEI. I have to say, in my 60+ years of life, I don't think I have ever met doctors as expert, caring, and kind as Dr. Gelles (specialty contact lens optometrist) and Dr. Greenstein (cornea surgeon.) They are not only experts at what they do, but they are thorough in their diagnoses, clear in their explanations, patient in answering every single question I have, and they never stop working to get the best result. Whether it's getting the best possible specialty lens, or the best possible surgical solution (I've had both), I just can't say enough about these guys. Perhaps this says it best: I live on Long Island; to get there, I have to take the George Washington Bridge. For 3 years now, I have willingly braved the Cross Bronx Expressway to get to CLEI. Anyone who lives in this area will understand that there is no higher compliment than, "You are worth a trip on the Cross Bronx Expressway." 😂😂

Thank you so much Doc! When I first came to you I was 20/50 now I'm 20/10. I'm ready to have a great year!

Dr. Hersh and his staff were excellent. I was comfortable from the time I walked in until the time I left after the procedure.
