Resumo: | Purpose: To present photorefractive keratectomy (PRK) results for myopia ranging from -4,00 to - 6,00 diopters performed with the VISX and Summit excimer lasers. Methods: To be eligible for this study, patients had to be 20 to 45 years of age, have -4.00 to -6.00 diopters of myopia and have no more than 1 D of astigmatism. The Summit group was composed of 51 eyes. The baseline preoperative spherical equivalent of myopia was -5.22 ± 0.17 and surgeries were performed with the Excimed UV 200 LA Excimer Laser. In the VISX group, there were 53 eyes and the baseline refractive error was -4.85 ± 0.16 and surgeries were performed with the Twenty/Twenty Excimer Laser. Results: At six-month examination, haze ranged from 0 to 1 (M:0.56 ± 0.07) in the VISX group and from 0 to 3 (M:0.58 ± 0.08) in the Summit group. Uncorrected vision at six months was 20/20 or better in 22% of eyes and 20/40 or better in 83% of eyes in the VISX group. In the Summit group, 25% of eyes were 20/20 or better and 71% were 20/40 or better at the six-month examination. Conclusion: It is reassuring that PRK of patients with -4.00 to -6.00 D of myopia results in acceptable results. |
