Dr. Siano is the best. After wrong diagnoses for six months and seeing three other doctors, I was referred to ReFocus. The experience was amazing and friendly. He did surgery that resolved my issue—couldn’t recommend him more highly.

Dr. Siano was thorough, informative and friendly. His staff walked me through vision tests and eye scans and administration of eye dilation drops with minimal wait times. Very happy with the Dr. and his staff.
