New FDA Clinical Trial For Keratoconus And Ectasia

San Diego, CA – The first Collagen cross-linking (CXL) study case in the western United States was performed April 28, 2008, in San Diego at Gordon Binder & Weiss Vision Institute by renowned eye surgeon Dr. Perry S. Binder. The goal of the study is to evaluate the benefits of collagen cross-linking in patients with progressive keratoconus or corneal ectasia after corneal refractive surgery.

The FDA recently completed its review of the keratoconus and ectasia clinical study protocols and gave permission to begin enrollment of 160 patients into each study at up to 20 investigative sites in the United States. CXL is a procedure that stiffens the cornea by exposing it to ultraviolet (UV) light after it is saturated with riboflavin (vitamin B2). The light interacts with the riboflavin to produce chemical bonds between collagen molecules. This makes the cornea less likely to bow forward as it does in keratoconus or ectasia after LASIK.

Corneal collagen cross-linking was developed at the University of Dresden in Germany, and has been under investigation there since 1998. Studies in Europe have shown that corneal collagen cross-linking improves biomechanical stability of the cornea and either stops or slows the progression of keratoconus and post-LASIK ectasia.

“The procedures were simple to perform and no adverse effects were encountered” according to Dr. Perry S. Binder of Gordon Binder & Weiss Vision Institute. “We are eagerly awaiting additional procedures to gain further insight into the safety and effectiveness of this treatment for a disease that heretofore was only treatable with corneal transplantation.”

Gordon Binder & Weiss Vision Institute is one of ten sites in the United Statesselected to participate in the collagen cross-linking study. The local participating surgeons are Dr. Michael Gordon, Dr. Perry S. Binder, and Dr. Jack L. Weiss, corneal specialists who perform refractive, corneal and cataract surgery at the Gordon Binder & Weiss Vision Institute.
