PRK: In Practice
Combine procedures, improve patient outcomes
David Sung Yong Kang | | Quick Read
In my practice, most refractive surgery patients undergo either small incision lenticule extraction (SMILE) or transepithelial PRK (TPRK). A smaller percentage of high hyperopes and high myopes are offered hyperopic LASIK or phakic IOL surgery. Several years ago, I decided that offering simultaneous accelerated cross-linking (CXL) to my TPRK patients was an obvious choice to complement the biomechanical stability of TPRK.
A number of other authors have reported on combinations of CXL and excimer laser surgery in eyes with keratoconus, so it is very important to note that we only perform the TPRK-CXL procedure in eyes that are absolutely normal. We are not expanding the indications of refractive surgery to eyes with forme fruste keratoconus or suspect topography. Rather, we are adding the benefits of cross-linking and an extra measure of safety for those who already qualify for TPRK.
