Abstract Details

Purpose:

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

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
