Abstract Details


To evaluate the efficacy of transepithelial photorefractive keratectomy (transPRK) using the Schwind Amaris excimer laser for the treatment of myopia.


Vedis Augenlasercenter Zurich


Prospective consecutive clinical study of 22 eyes (12 patients, mean age 32.4 ± 6.8 years) who were treated by transPRK using the aberration free ablation protocol. The optical zone was 7 mm and standard epithelial thickness (centrally 55 µm and 65 µm in the periphery) was used. In 8 eyes Mitomycin C 0.02% for 30 seconds was applied. We report our first 12 months results.


Mean refractive spherical equivalent changed from -2.75 ± 1.55 to -0.11 ± 0.29 postoperatively. 2 eyes lost one line of best spectacle-corrected visual acuity (BCVA), although all eyes reached BCVA of 1.0 or better. The uncorrected distance visual acuity (UDVA) changed from 0.15 ± 0.1 to 1.1 ± 0.14 (range 0.8 – 1.2). 19 eyes (86.4%) achieved a UDVA ? 1.0. Haze Grade 1 appeared in 4 eyes (reversible with topical steroid treatment).


TransPRK appears to be a safe and effective therapeutic option for low to moderate myopia. FINANCIAL DISCLOSURE?: No
