I have keratoconus and the RGP contact lenses I had from another doctor were uncomfortable, I had vision issues and they would either pop out or displace at the most inopportune times. I read about scleral lenses for keratoconus and found Dr. Quaranta on the Internet. He and his staff are so professional and friendly and were very patient with my stubborn eyes. End result is very comfortable scleral contacts that have eliminated my vision and other problems I had with RGP. Thank you!
