My dad was very fond of Dr. Hershs father. Hes an ophthalmologist in the area, and really appreciated the late Dr. Hersh. Of course, when it was time for me to get LASIK, he recommended Dr. Peter Hershs practice to me in a heartbeat.I got a great consultation with Dr. Greenstein and the follow-ups were flawless. By the end of my first day post-op, I was seeing 20/15. They do a really good job at keeping you calm and they take really good care of your eyes. The practice is warm and inviting, and the expertise of the doctors is top-notch.Thank you Dr. Hersh & Dr. Greenstein. I hope to be one of your colleagues one day as you both and my father really inspired me to go into ophthalmology.
I recently had to have laser surgery due to Keratoconus. They r so thorough pre-op & the day of, making absolutely sure there r no changes. Then there is a next day post-op exam, then a 5-day follow up & a 30-day. Dr. Greenstein is very responsive to any calls of concern. All has gone very well & full healing takes 3-4 months. But Im feeling great & vision continues to improve. I have full confidence in the end, it will b a complete success!! I highly recommend the Cornea & Laser Eye Inst.
Ive been coming to the Cornea institute for a few years now. As soon as you walk in Jen greets you with a smile. As does her counterpart. There is a warm feeling in the office. I had a procedure done on both my eyes Dr. Greenstein is so professional. He explains everything thoroughly step by step. I feel very confident with him. He is also gentle. The medical assistants are wonderful. Calming and warm. I would recommend this practice for sure.
