目的:评价准分子激光屈光性角膜切削术(photorefractive keratectomy PRK)术后屈光状态的变化。方法:将随访2年、资料完整的PRK术后的234例(391眼)患者分为两组:Ⅰ组为低中度组(<6.00D)228眼,Ⅱ组为高度组(>6.00D)163眼,分别对术后3、6、12、24个月的屈光状态进行随访。结果:PRK术后2年屈光回退高于-0.5D、过矫、欠矫>1D、术后残留散光、手术性散光、远视漂移等发生率在低中度组分别为1.7％、4.4％、5.7％、12.8％、7.4％、7.5％。在高度近视组分别为15.9％、4.9％、23.3％、29.7％、31.1％、6.7％。结论:从屈光状态变化的分析更进一步证实PRK对治疗低中度近视眼是一种准确、稳定、安全、有效、能预测的好方法,而对高度近视眼的治疗效果稍差。眼科学报2000;16:143-145。
Objective: To evaluate the changes of refractive status after photorefractive keratectomy (PRK). METHODS: A total of 234 eyes (391 eyes) with PRK postoperative follow-up of 2 years were divided into two groups: group Ⅰ (228 eyes) with low-moderate degree (<6.00D), group Ⅱ ) 163 eyes were followed up 3,6,12,24 months postoperative refractive status. Results: The refractive error of PRK was higher than -0.5D at 2 years after operation. The overcorrection and overcorrection> 1D, the postoperative residual astigmatism, surgical astigmatism and hyperopia drift were 1.7%, 4.4% %, 5.7%, 12.8%, 7.4%, 7.5%. In the high myopia group were 15.9%, 4.9%, 23.3%, 29.7%, 31.1%, 6.7%. CONCLUSIONS: The analysis of changes in refractive status further confirms that PRK is an accurate, stable, safe, effective and predictable method for the treatment of low and moderate myopia, while the treatment of high myopia is somewhat less effective.
