Purpose:

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

Setting:

Vedis Augenlasercenter Zurich

Methods:

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.

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).

Conclusions:

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