Abstract Details


To determine safety and outcomes of PTK followed by delayed Transepitelial link for small irregularities due to scars, haze and corneal distrophies


DR. Massimo Camellin, Sekal Rovigo Microsurgery Centre, Rovigo, Italy


24 eyes receiving PTK procedure for reducing small irregualities on the cornea. As second procedure, followed after at least one month, a customized transepithelial link has been performed to fix low order and high order aberrations. In all cases MMC 0,02% for 2 min has been used. Keratron-Scout topography (Optikon 2000) and a flying-spot laser (AMARIS; SCHWIND eye-tech-solutions) has been the used platform.


All cases have improved there BCVA and following the transepitelial link, high order and low order aberrations have reduced as well. BCVA passed from 4,9/10 to 6,7/10 and RMS Value in 5mm passed from 2,1micron to 1,3micron .UCVA pre was 2,5/10 and post was 4,3 .The mean age of the patients was 40,5 years (range 26 to 64 years) at the time of the surgery. Mean follow-up was 30±15 months (2 to 50 months). No Snellen lines of BSCVA lost, and 11 eyes (50%) had an increase of more than 1 lines. Haze was 0 in all eyes.


When the cornea surface is too irregular to achieve a good topography, it is necessary to smooth the surface with a PTK procedure by means of a mask fluid and wait for at least a month before reprocessing the image. At this point, it is easy to perform a transepithelial link to fix all refractive errors.
