Purpose:To determine if the visual acuity results of hyperopic prk differ based on the excimer laser platform used, and compare the results of hyperopic prk to those of hyperopic lasik. Methods:Retrospective chart review of 135 consecutive hyperopic prk cases performed by one surgeon using either the Alcon Wavelight Allegretto EyeQ 400 wavefront-optimized (WFO) (31 eyes), AMO VISX Star S4 IR conventional (VSX) (83 eyes), or AMO VISX Star S4 IR wavefront-guided CustomVue (CV) (21 eyes) excimer platforms. All cases had a minimum follow-up of three months. Patient demographics, preoperative vision data, and post-operative uncorrected visual acuity (UCVA) were collected and analyzed. Results were also compared to previously reported hyperopic lasik results. Results:20/20 or better UCVA was obtained in 21 of 31 WFO eyes (68%), 49 of 83 VSX eyes (59%), and 17 of 21 CV eyes (81%). These differences are not statistically significant (Fisher’s exact test): WFO vs CV, p=0.35; WFO vs VSX, p=0.52; CV vs VSX, p=0.08. 20/25 or better UCVA was obtained in 23/31 (74%) WFO, 67/83(81%) VSX, and 19/21 (90%) CV eyes. These differences are not statistically significant (Fisher’s exact test). UCVA results for mixed astigmatism prk vs hyperopic astigmatic prk , and hyperopic prk vs hyperopic lasik were also not significantly different. Conclusion: Good UCVA results were obtained with hyperopic prk done on each of the platforms studied. There was no statistically significant difference in achieved UCVA between these three platforms. These UCVA results are not significantly different from those previously reported for hyperopic lasik.
