AB  - AIM: To evaluate refractive and visual outcomes of photorefractive keratectomy
      (PRK) to treat high hyperopia using an aberration-neutral profile and large
      ablation zone. METHODS: This was a retrospective, consecutive observational case 
      series at the Oftalmika Eye Hospital, Bydgoszcz, Poland. We included 51
      consecutive eyes of 34 patients who underwent alcohol-assisted PRK to correct
      hyperopia within the range of +3.6 to +6.15 D (mean+4.61+/-0.67 D). Procedures
      were performed with an Amaris 750S excimer laser (Schwind eye-tech-solutions
      GmbH, Kleinostheim, Germany) using an aberration-neutral profile and a 10 mm
      total ablation zone. Refractive results, predictability, safety and efficacy were
      evaluated 3 years postoperatively. RESULTS: At 1-year postsurgery, the mean
      manifest refraction spherical equivalent (MRSE) was -0.002+/-0.43 D and mean
      cylinder was -0.181+/-0.31 D, while the values were +0.09+/-0.46 D and
      -0.15+/-0.26 D, respectively, at 2 years (MRSE p<0.001) and +0.15+/-0.44 D and
      -0.15+/-0.26 D, respectively, at 3 years (MRSE p<0.001). 78% of eyes were within 
      +/-0.50 D of the attempted spherical equivalent correction. Three years
      postoperatively, 22% of eyes lost one line of corrected distance visual acuity
      and 27% gained a line or two. The change in the mean corneal spherical
      aberrations for the 6 mm zone was from 0.27+/-0.07 to 0.08+/-0.13 microm.
      CONCLUSIONS: High hyperopia correction with PRK using an aberration-neutral
      profile and large ablation zone provides good efficacy, safety, predictability
      and visual outcomes. Relatively low change of corneal spherical aberrations and
      low increase of hyperopia in the first three postoperative years were observed.
