Abstract Details


To evaluate refractive and visual outcomes of photorefractive keratectomy (PRK) in the treatment of moderate hyperopia with the use of aberration-neutral profile and large ablation zone.


Oftalmika Eye Hospital, Bydgoszcz, Poland, Collegium Medicum NCU, Bydgoszcz, Poland


This retrospective, consecutive, observational case series comprised 57 eyes of 21 patients who underwent alcohol-assisted PRK to correct hyperopia within the range of 3.6 to 6.15 D (mean SE +4.59±0.66 D). All procedures were performed with Amaris 750S excimer laser (Schwind eye-tech-solutions GmbH, Kleinostheim, Germany) using aberration-neutral profile and the maximum diameter of total ablation zone feasible with the system (10 mm). Refractive results, predictability, safety, and efficacy were evaluated post-operatively at 2 to 3 years follow-up.


Mean postoperative MRSE was -0.01±0.41D, mean cylinder was 0.19±0.31D 1 year after the surgery (n=50); these metrics respectively changed to +0.08±0.44D, 0.16±0.27D 2 years post-operatively (n=49, paired t-test p=0.001), and +0.26±0.46D, 0.13±0.23D 3 years post-operatively (n=19, paired t-test p=0.1). Correlation between attempted versus achieved MRSE was very good (R2=0.7745, slope=0.887, intercept=0.39D). 80% of eyes were within ±0.50 D of attempted spherical correction. UDVA of 20/20 or better was seen in 20% of eyes preoperatively, and 85% of the eye 24 months post-operatively. One year after the procedure 22% of eyes lost one or two lines of CDVA and 28% gained a line or two.


Photorefractive keratectomy with the use of aberration-neutral profile and large ablation zone provides good results in terms of efficacy, safety, predictability, and visual outcomes. Only minimal regression was observed in the first 3 years postoperatively.
