Dr. Rapuano, originally from Northern New Jersey, joined the Cornea Service at Wills after his fellowship in 1991. He was instrumental in reintroducing refractive surgery to Wills at that time. Dr. Rapuano is a nationally and internationally recognized expert in corneal diseases, with a special interest in refractive surgery. He feels that cornea specialists are particularly skilled at performing LASIK, which essentially involves reshaping the cornea. As a cornea specialist who performs LASIK, he is especially good at determining who is and is not a good candidate for LASIK, thereby decreasing the risk of complications after LASIK. Dr. Rapuano performs all pre-operative and post-operative care for his LASIK patients. When complications occasionally occur, other LASIK doctors refer their patients to Dr. Rapuano for his expertise and care.

He has published several books and over 100 research papers in the medical literature on corneal diseases and excimer laser PTK surgery. During his ophthalmology residency, Dr. Rapuano co-authored a best-selling textbook in ophthalmology, The Wills Eye Institute Manual. This book is considered the bible to ophthalmology residents throughout the country during their training, and it is in its 4th edition. He recently published The LASIK Handbook — A Case-Based Approach. Dr. Rapuano serves on many committees of the American Academy of Ophthalmology and on the editorial boards of numerous peer-reviewed ophthalmology journals, including the American Journal of Ophthalmology. He is a member of the American Ophthalmalogical Society.

Dr. Rapuano lives with his wife, Sara, and their four children in the Philadelphia suburbs. Sara is involved in the administration of Wills Eye.
