Our Program

12:30 – 13:30Lunch Served  



13:30 – 15:00The state of the art in corneal remodeling for keratoconus. 
Modern refractive and corneal techniques such as CXL, intracorneal ring segments, PRK and phakic IOLs may be used as standalone or in sequential procedures for visual rehabilitate keratoconus patients. The course will provide detailed instruction on technique selection and execution according to individual patient characteristics.
