To confirm the effectiveness of the 193 nm excimer laser to correct low myopia (1.00 to 6.00 D), moderate myopia (6.00 to 10.00 D), and high myopia (10.00 D and above).
One hundred eighty-one eyes of 114 patients underwent excimer laser photorefractive keratectomy (PRK). The minimum follow-up was 12 months.
After one year, 96% of the eyes in the low myopia group, 69% in the moderate myopia group and 29% in the high myopia group achieved uncorrected visual acuity of 20/40 or better with one treatment using a single application with a 5 mm optic zone. There were no significant major complications.
PRK is a safe, effective and relatively accurate procedure to correct low to moderate myopia.
确认193纳米准分子激光矫正低度近视（1.00至6.00 D）、中度近视（6.00至10.00 D）和高度近视（10.00 D及以上）的有效性。
114例患者的181只眼接受了准分子激光屈光性角膜切削术（PRK）。最短随访时间为12个月。
一年后，低度近视组96%的眼睛、中度近视组69%的眼睛和高度近视组29%的眼睛在使用5毫米光学区单次治疗后裸眼视力达到20/40或更好。无重大显著并发症。
PRK是矫正低度至中度近视的一种安全、有效且相对精确的手术。
