“…In the study by Frings A et al (2016), the mean SE before the PRK decreased from +1.04±0.58 to -0.08±0.38 at the 6 months postop [ 19 ]. Kaluzny BJ et al (2018) revealed that the mean SE decreased from +4.61±0.67 with a range of 3.6–6.15 D to -0.002±0.43 D at the 12 months postop [ 13 ]. Many other studies confirmed the significant decrease of the mean SE after PRK [2, 7–10, 12, 14, 15, 17, 20], which is in line with data from this study.…”

“…According to Autrata R et al [ 18 ], after 2 years of follow-up, 86% of patients in the PRK group showed an emmetropia of ±1.00 D interval and 57% SE of ±0.5 D in their eyes. In the studies by Kaluzny BJ et al [ 13 ] and Yenugandula R et al [ 21 ] (after 3 years), 78% and 92% of the eyes were in the range of ±0.5 and ±0.1.00 D, respectively. Also, in a study by El-Agha MS et al [ 4 ], in the PRK group, after one year, 83.3% and 100% of the eyes had an SE of ±0.5 D and ±1.00 D, respectively, which was not in line with our results.…”

“…In a study by Kaluzny BJ et al [ 13 ], 9.8% of the eyes had corneal haziness with a mean of 0.6 at the 12 months after PRK. Furthermore, another study reported that 25% and 70% of the eyes had haziness and iron ring 7 years after PRK [ 10 ].…”

“…Preoperative UCVA in the PRK group increased from mean LogMAR of 0.37±0.28 to mean LogMAR of 0.03±0.11 at 6 months postop [ 19 ]. Furthermore, UCVA ≥20/20 was observed in 59% of eyes at the 3 years postop [ 13 ] and vision ≥20/40 was observed in 78.4% of the eyes at the 3 years postop [ 21 ]. In O'Brart DP et al study [ 10 ], the UCVA ≥20/20 and ≥20/40 was observed in 15% and 57.5% of the eyes, respectively.…”

This study aimed to examine the effectiveness of photorefractive keratectomy (PRK) in treating patients with cycloplegic hyperopia from +1.00 to +7.00 diopter using Allegretto wave Eye Q 400. This study was conducted on 25 patients with cycloplegic astigmatism ≤1 diopter and cycloplegic hyperopia between +1.00 and +7.00 diopters in 47 eyes, who successively entered into the study within 6 months and underwent PRK. Prior to PRK surgery, all the patients were examined for cycloplegic refraction (astigmatism and hyperopia), slit lamp, keratometry, fundus, and best-corrected (BCVA) and uncorrected visual acuity (UCVA) testing. These examinations were repeated after 1 week, 1 month, 3 months, 6 months, and 1 year postoperatively. The mean preop UCVA of patients was 0.76±0.28 (ranging from 0.00 to 1.3), which reached 0.19±0.22 (ranging from 0.00 to 0.78) one year after the surgery (P=0.000). There was a significant correlation between increasing astigmatism and preop cycloplegic hyperopia >5 diopters (P=0.000), corneal ring haziness at 12th months (P=0.000), and 12 months cycloplegic residual hyperopia ≥2.00 diopters (P=0.000). 53.2% of the eyes (with a mean grade of 2.34) were detected with corneal ring haziness at 12th months, which was significantly correlated with 12 months residual cycloplegic hyperopia of ≥2.00 diopters (P: 0.000) and cycloplegic sphere above 5 diopters (P=0.006). Although the use of photorefractive keratectomy (PRK) with Allegretto Eye Q 400 is associated with a decrease in the mean cycloplegic and improved UCVA and BCVA, its use is not recommended in cases with preop cycloplegic hyperopia above 5 diopters due to the high rate of induction of astigmatism, corneal haziness, and regression of hyperopia.

Purpose: To evaluate refractive and visual outcomes of single-step transepithelial photorefractive keratectomy (transPRK) in the treatment of mixed astigmatism with the use of an aberration-neutral profile and large ablation zone. Setting: Nicolaus Copernicus University and Oftalmika Eye Hospital, Bydgoszcz, Poland. Design: Retrospective, observational case series. Methods: This study included patients who underwent transPRK to correct mixed astigmatism and completed the 3-year follow-up. Procedures were performed with an Amaris 750S excimer laser using an aberration-neutral profile and optical zone of 7.2 mm or more. Results: A total 48 eyes of 39 patients were included. Preoperatively, mean spherical manifest refraction was +1.37 ± 0.98 diopter (D) (0.25 to 4.00 D), and astigmatism was −4.00 ± 0.76 D (−2.25 to −6.00 D). Three years postsurgery, it was −0.17 ± 0.26 D and −0.41 ± 0.44 D, respectively. Attempted spherical equivalent correction within ±0.50 D was achieved in 45 eyes (94%) and cylindrical correction in 34 (71%). Preoperative corrected distance visual acuity (CDVA) was 20/20 or better in 38 eyes (79%), and postoperative uncorrected was 20/20 or better in 29 eyes (60.0%). No eye had lost 2 or more Snellen lines of CDVA, whereas 3 eyes (6%) gained 2 or more lines. In 4 eyes (8%), haze of low intensity was observed at the periphery, with scores between 0.5 and 1.0, and only 1 eye getting a score of 2 in 0- to 4-degree scale. Conclusions: Mixed astigmatism correction with large-ablation-zone transPRK provided good results for efficacy, safety, predictability, and visual outcomes in a 3-year follow-up.
