Dr. Hersh and Dr. Greenstein both went on to complete additional specialized fellowship in corneal surgery after residency.

Corneal cross-linking (CXL) is the latest advancement in technology for treating keratoconus. Corneal collagen cross-linking strengthens the cornea by allowing it to reform new cross-links between collagen fibers. The cross links strengthen the cornea, which stops the thinning process and further loss of vision.

Dr. Peter Hersh is an internationally recognized expert for corneal cross-linking and has written several articles in peer reviewed publications. Based on more than a decade of research on CXL the results appear to be solid and long lasting. Evidence is leaning towards CXL having permanent results. As a renowned expert, Dr. Hersh will consult and discuss CXL with patients from all over the world.

Corneal Cross Linking / Keratoconus Treatment

Keratoconus is an eye condition resulting in a thin and irregular cone-shaped cornea. This is caused by a weakening of the cornea structure with progressive distortion of the corneal optics. Treatments for keratoconus can include a corneal collagen crosslinking, Intacs,conductive keratoplasty, cornea transplant, and contact lenses, and new procedures currently being developed for the treatment of keratoconus. Dr. Hersh and The CLEI Center for Keratoconus have been performing the corneal crosslinking for keratoconus procedure since 2008, leading clinical trials for keratoconus treatment in the U.S.
