If you live in NY, NJ or really anywhere in the eastern US, this is the place to get your eye treatment done. I speak as someone with keratoconus who'd gone to half a dozen of practices in New York before committing to Dr. Greenstein. He tells it to you like it is, no fluff, while performing surgeries expertly and precisely. I said surgeries because I had two with him - a partial corneal transplant and PRK, both of which I needed. Im happy with the outcomes. Also shoutout to the medical and front desk staff who've consistently treated me very well.

Excellent results. Excellent bedside manner. Great staff. Educated well by the docs and staff to make a well informed medical/surgical decision with my eyes. Safety a top priority. Ease of combination eye drop regimen from compounding pharmacy. 5/5 stars and very satisfied with both immediate and future long term outcomes.

The best, most careful, most caring doctors you would ever want to find. I had complicated issues with my corneas and, as I got older, with cataracts. Not only do Drs. Greenstein and Gelles take all the time you need to have everything explained, but they don't rest until you have received the best possible outcome. When I needed specialty contact lenses, the ones I got at first were pretty darned good, but Dr. Gelles saw that they could be tweaked to be even better. And they were!I honestly don't have enough words for how much I recommend these doctors!
