中文摘要 | 背景:鑑於近視在台灣之高盛行率,我們因而分析高度近視眼接受白內障摘除術之方法,影響術後視力之因素,及雅鉻鐳射後囊切開術後產生視網膜併發症之比率。 方法:收集125隻眼軸大於26毫米之高度近眼接受白內障手術。手術方法包括晶體乳化術併人工水晶體植入,囊外白內障摘除併人工水晶體植入,晶體乳化術,及囊外白內障摘除。記錄術前及術後最佳矯正視力及視網膜併發症的時間。以logistic regression探討影響術後視力之因素。 結果:41眼(32.8%)術後增加四行之視力。32眼(25.6%)可達滿意的術後視力,即最佳矯正視力大於等於0.5,26眼(20.8%)為較差之術後視力,即最佳矯正視力小於0.1。在術後視力較佳這組中(最佳矯正視力大於0.1),發現年齡較輕及眼軸較短。後囊混濁為白內障術後最常見之併發症,而雅鉻鐳射後囊切開術為其治療方式。然而125隻眼中3隻眼睛(2.4%)產生視網膜併發症,其中2隻眼睛於雅鉻鐳射後囊切開術施行一個月內發生視網膜剝離。 結論:在此報告中大部分高度近視白內障術後視力皆有所進步。老年高度近視又具明顯脈絡膜視網膜退化是術後視力無明顯進步之主要因素。雖術前介質混濁致眼底檢查不易,年齡及眼軸為高度近視術後視力之預期因素。既然雅鉻鐳射後囊切開術是術後後囊混濁主要治療方式,鐳射前詳細眼底檢查避免視網膜併發症是非常重要的。 |
英文摘要 | Background: According to the high prevalence of myopia in Taiwan, we analyze the adopted cataract extractions, identify predicting factors for postoperative vision, and to assess the incidence of retinal complications after Nd: YAG laser capsulotomy in high myopic eyes. Methods: One hundred and twenty-five eyes, which the axial lengths were longer than 26 mm, following cataract extraction were enrolled. Surgeries adopted included phacoemulsification with intraocular lens implantation, extracapsular cataract extraction with intraocular lens implantation, phacoemulsification, and extracapsular cataract extraction. Logistic regression was utilized to assess predictive factors for postoperative vision. Results: Postoperative vision of 41 eyes (32.8%) of the 125 high myopic eyes improved at least 4 lines of Snellen acuity. Thirty-two eyes (25.6%) achieved good postoperative vision (BCVA[]20/40). And 26 eyes (20.8%) demonstrated poor postoperative vision. (BCVA<20/200). Younger age and shorter axial length were appreciated for better visual outcome (p<0.05). Nd: YAG laser capsulotomy is required for posterior capsular opacity. Three in 125 eyes (2.4%) developed retinal complications and 2 of them had retinal detachment subsequently within one month after Nd: YAG laser capsulotomy. Conclusion: Most high myopic patients achieved visual improvement after cataract surgeries. Age and axial length are the predictive factors in high myopic patients. It is crucial to examine retina prior to Nd: YAG laser capsulotomy to prevent retinal complication. |
