中文摘要 | 目的:比較不同厚度之角膜板層刀合併前導波雷射角膜原位成型術,用以治療高度近視之效果及安全性評估。 方法:以回溯性研究方法,分析自九十三年十二月至九十四年二月共二十七位患者,五十一隻高度近視眼,以三種不同刀片,進行角膜瓣切割之前導波雷射角膜原位成型術,術後視力、高階像差、合併症發生進行臨床統計。 結果:追蹤時間大於六個月以上,三組均有相似術後視力 (p>0.05) 與高階像差 (p>0.05),未因不同刀片而產生相異的合併症發生機會。 結論:前導波雷射角膜原位成型術用以治療高度近視是一項相對有效且安全的方法,雖在不同的角膜板層刀不同的角膜瓣膜厚度下,依然有近似的結果。 |
英文摘要 | Purpose: To study and compare the visual outcomes of wavefront-guided laser in situ keratomileusis (LASIK) by Mona M2 microkeratomes using different blades for the treatment of high myopia and evaluate the complication rate during the operation and postoperatively. Methods: This retrospective study included 51 consecutive eyes of 27 patients (14 males & 13 females) whose spherical equivalence greater than -6 diopters treated with Visx S4 wavefront -guided LASIK from December 2004 to February 2005 and followed 6 months. Their mean age was 29.6 years. All patients underwent complete preoperative ophthalmologic examination, including wavefront aberrometer (VISX wavefront system). Final refraction, refractive changes, uncorrected visual acuity, ablation volumes, total aberrations, high order aberrations (HOA) were evaluated. Result: The patients were divided into three groups: Group I by Mona M2-90 head, Group Ⅱ by Mona M2, Med-logics M17050 blade and Group III by Mona M2-130 head. The data was analyzed by ANOVA method. Between the three groups, the differences of uncorrected visual acuity in 6 months postoperative were not significant (p>0.05). Total aberrations and high order aberrations in 6 months postoperative remained no statistically significance (p>0.05) Conclusion: The uncorrected visual acuity, total aberrations and high order aberrations of three groups achieved the same results in 6 months postoperatively. |
