Abstract

Majid Moshirfar1 Maylon Hsu1 Yousuf M Khalifa21Moran Eye Center, Salt Lake City, UT, 2Flaum Eye Institute, Rochester, NY, USAAbstract: The management of corneal ectasia is evolving, with intrastromal corneal ring segments playing an important role in delaying or eliminating the need for penetrating keratoplasty. This paper describes a modification in the implantation technique of intrastromal corneal ring segments that allows for coupling of the two segments with suture, affording more structural support.Keywords: intrastromal corneal ring segments, Intacs, keratonconus, corneal ectasia, keratoectasia
