60 EW MEETING REPORTER Reporting live from the 2013 American Academy of Ophthalmology Annual Meeting in New Orleans December 2013 "A patient who is not a candidate for a successful corneal transplant is a patient who is good for a keratoprosthesis," he said. Preoperative evaluation is key in these cases, Dr. Perez said. He presented a video of a modified osteo-odonto-keratoprosthesis (MOOKP) case, where a canine tooth was implanted into the eye. Other physicians who presented at the symposium were Francis W. Price Jr., MD, Indianapolis, who discussed what the future holds for endothelial keratoplasty; Rajesh Fogla, MD, Hyderabad, India, who presented advances in deep anterior lamellar keratoplasty with a bubble; Marjan Farid, MD, Irvine, Calif., who talked about femtosecond-assisted keratoplasty; Clara C. Chan, MD, Cincinnati, who offered tips for success with therapeutic keratoplasty; Deepinder K. Dhaliwal, MD, Pittsburgh, who discussed management of a failed graft; and Gerald W. Zaidman, MD, Valhalla, N.Y., who gave an update on pediatric keratoplasty. Editors' note: The physicians have no financial interests related to their presentations. Femtosecond laser technology In the "Advanced Application of Femtosecond Lasers for Refractive Surgery" session, a number of surgeons discussed the development and advancement of the femtosecond technology and the ways in which it has changed corneal and refractive surgery. Perry Binder, MD, San Diego, presented a short overview of femtosecond laser technology and said the diagnosis of its capabilities began on accident. Now, he said, there are numerous platforms that have evolved. He cited several goals moving forward with femtosecond laser technology, including increasing procedure speed, reducing the laser energy to eliminate potential side effects, creating additional applications and trying to find one laser that will be able to do it all. Steven Schallhorn, MD, San Diego, discussed using the femtosecond laser for LASIK procedures. "I believe the femtosecond laser, particularly for a LASIK flap, is more con- Scan QR code to go to EWrePlay.org John Kanellopoulos, MD, Athens, Greece, and New York, (right) describes topographic changes to the corneal epithelium in pathology and in response to keratorefractive surgery. guna Hills, Calif.).
