Hyperopia is a type of refractive error and photorefractive keratectomy (PRK) is one of the surgical procedures for correction of various types of refractive errors. In this study we decided to evaluate the efficacy and results of PRK on hyperopia of more than 3 diopters 4 months after surgery. Background: Overall, 30 eyes of 19 patients (18-66 years of old) for this clinical trial study were selected from the patients referred to an  eye center clinic for PRK. All of these eyes were operated by Technolas 217 Excimer laser system. 4 months postoperative results were compared with preoperative data. Pre and postoperative results were compared using t-paired test via SPSS software. Methods: Postoperative spherical equivalent of patients were - 2.00 to + 5.00 diopter. In 30% of patients there was overcorrection and in 70% of patients there was Undercorrection. None of the patients were in the range of emetropia. Postoperative SE of 46.6% of patients was in the range of ± 1.00 diopter and 80% of patients were in the range of ± 2.00 diopter. The mean preoperative best corrected visual acuity (BSCVA) of patients 0.8 ± 0.18 as well as postoperative BSCVA. The mean of uncorrected visual acuity (UCVA) was 0.13 ± 0.1 and the mean of postoperative UCVA vs 0.51 ± 0.25. The mean of preoperative sphere was +5.45±2.06 and post operative one was + 1.00 ± 1.62 diopter. The mean of preoperative astigmatism was - 1.42 ± 1.13 that change to - 0.95 ± 0.55 postoperatively. Findings: Photorefractive keratectomy has a poor predictability and efficacy for hyperopia of more than + 3.00. Conclusion: High hyperopia - Hyperopia - Photorefractive Keratectomy. Key words:
