Bottom Line: BCVA increased by two lines or more in three eyes (7.1%) and one line in two eyes (4.7%); 31 eyes showed no change, three eyes (7.1%) lost one line, and three other eyes (7.1%) lost two lines of BCVA.No eyes lost more than two lines of BCVA.Complications included Grade 2 peripheral haze in two eyes which cleared by 12 months postoperatively.

ABSTRACT

Purpose: To evaluate refractive and visual outcomes of photorefractive keratectomy with mitomycin-C. (PRK-MMC) for the treatment of mild to moderate hyperopia.

Materials and methods: This case series enrolled 21 patients with up to +5.50 diopters (D) of hyperopia. All 42 eyes were treated with the Concerto (Wavelight) or the Technolas 217-Z (Bausch and Lomb) excimer laser. Outcome measures included best corrected distance vision acuity (BCVA) and uncorrected distance vision correction and refraction at 1, 3, 6, and 12 months postoperatively.

Results: Mean patient age was 44.8 ± 11.3 years. Preoperatively, mean manifest refractive spherical equivalent (MRSE) was + 2.00 D ± 0.76 D and mean spherical refractive error was + 2.57 D ± 0.87 D (range, +1.25 D to + 5.50 D). At 12 months postoperatively, mean MRSE was + 0.1 D ± 0.61 D. MRSE was within ± 0.50 D of emmetropia in 29 eyes (69%), and 18 eyes (43%) had 20/20 uncorrected distant visual acuity. BCVA increased by two lines or more in three eyes (7.1%) and one line in two eyes (4.7%); 31 eyes showed no change, three eyes (7.1%) lost one line, and three other eyes (7.1%) lost two lines of BCVA. No eyes lost more than two lines of BCVA. Complications included Grade 2 peripheral haze in two eyes which cleared by 12 months postoperatively.

Conclusion: PRK-MMC was a safe and predictable method for the correction of mild to moderate hyperopia.

Figure 1: Logarithm of the minimum angle of resolution uncorrected distance visual acuity and best spectacle-corrected distance visual acuity preoperatively and at 1, 3, 6, and 12 months after surgery

Mentions: Forty-two eyes of 21 patients were enrolled in this study. The mean age of the patients was 44.8 ± 11.3 years (range, 20–55 years) and eight cases (19%) were under 40. Two patients (9.55%) were males and 19 (90.45%) were females. Preoperatively, mean manifest refractive spherical equivalent (MRSE) was +2.00 D ± 0.76 D (range, 0.5–4.0 D) and mean spherical error was + 2.57 D ± 0.87 D (range, 1.25–5.5 D). Mean sphere and cylinder at different visits are summarized in Table 1. Figure 1 presents the changes in corrected and uncorrected visual acuity, and Figure 2 demonstrates changes in mean MRSE.
