摘　　要：目的对PRK和LASIK治疗近视并发症进行前瞻性的临床研究分析。方法对各屈光段近视741眼以随机方式分二组进行手术，其中PRK组（337眼），LASIK组（404眼）。术后随访3～12个月。将随访结果进行临床总结分析。结果屈光度欠矫和最佳矫正视力下降，PRK组均高于LASIK组，分别为20．5％和9．4％及26.4％和10．1％。视疲劳、老视现象两组均有。角膜雾浊（Haze）为PRK特有共发症，0．5～1级占19．3％，2级占2.5％。激素性高眼压PRK组9．8％，LASIK组0％。角膜层间异物和角膜瓣形成本完全是LASIK特有并发症。结论两组比较PRK比LASIK并发症多，且有的并发症处理较棘手，影响手术效果。LASIK术中存在某些潜在共发症，随手术技巧提高和熟练，可以避免。LASIK优于PRK。Objective To analyze the complications of excimer laser-insitu Keratomitusis and PRK for myopia. Methods 741 eyes with different diopters of myopia were randomly assigned to receive either PRK or LASIK. All the cases were followed up for a period of 3-12 months for observation.Results Under-correction and the reduction of the best corrected visual acuity occurred more in PRK group (20. 5%, 26.4% ) than in LASIK (9.4%, 10.1% ). Asthenopia and presbytia appeared in both two groups,while Haze only found in PRK group (0. 5-1 grade 19. 3%, 2 grade 2. 5% ). Cases in PRK group (9.8 %) were suffer from elevated intra-ocular pressure induced by steroid but none found in LASIK group.The intralamellar foreign bodies on corneal and the incomplete section of corneal disk only found in LASIK group.Conclusions Compared two groups,complications found more in PRK group and some of them were difficult to be treated, yet the complications in LASIK group can usually be avoided in pace with the improvement of operating skill.
