目的 应用双通道视觉质量分析系统研究后发性白内障行Nd∶YAG激光切开术后患者眼内散射的变化,客观评价术后视觉质量.方法 回顾性临床病例对照研究.对2007年5月至2013年12月在天津市眼科医院就诊的42例行白内障超声乳化+人工晶状体植人术后患有后发性白内障纤维型Ⅱ级及Ⅱ级以下膜,明显影响视力的患者行Nd∶YAG激光切开术.术前及术后2周散瞳前测量最佳矫正视力(BCVA),并将瞳孔充分散大,用裂隙灯数码相机进行眼底红光反射照相,联合Image Pro Plus6.0软件测量激光孔的大小.采用OQAS Ⅱ视觉质量分析系统测量4mm瞳孔下手术前后的客观散射指数(OSI),OQAS值(OVs),斯特列尔比(SR)和调制传递函数(MTF).结果 后发性白内障行Nd∶YAG激光切开术后2周,BCVA明显提高,logMAR视力由术前平均0.541提高到术后0.137,术后OSI值(3.263±2.118),较术前(12.148±3.511)明显减小,差异有统计学意义(t=16.818,P＜0.05),术后SR、MTF以及OVs较术前均有明显提高,差异有统计学意义(P＜0.05).结论 后发性白内障行Nd∶YAG激光切开术后2周,最佳矫正视力明显提高,眼内散射明显减小,术后视觉质量显著提高.
目的 應用雙通道視覺質量分析繫統研究後髮性白內障行Nd∶YAG激光切開術後患者眼內散射的變化,客觀評價術後視覺質量.方法 迴顧性臨床病例對照研究.對2007年5月至2013年12月在天津市眼科醫院就診的42例行白內障超聲乳化+人工晶狀體植人術後患有後髮性白內障纖維型Ⅱ級及Ⅱ級以下膜,明顯影響視力的患者行Nd∶YAG激光切開術.術前及術後2週散瞳前測量最佳矯正視力(BCVA),併將瞳孔充分散大,用裂隙燈數碼相機進行眼底紅光反射照相,聯閤Image Pro Plus6.0軟件測量激光孔的大小.採用OQAS Ⅱ視覺質量分析繫統測量4mm瞳孔下手術前後的客觀散射指數(OSI),OQAS值(OVs),斯特列爾比(SR)和調製傳遞函數(MTF).結果 後髮性白內障行Nd∶YAG激光切開術後2週,BCVA明顯提高,logMAR視力由術前平均0.541提高到術後0.137,術後OSI值(3.263±2.118),較術前(12.148±3.511)明顯減小,差異有統計學意義(t=16.818,P＜0.05),術後SR、MTF以及OVs較術前均有明顯提高,差異有統計學意義(P＜0.05).結論 後髮性白內障行Nd∶YAG激光切開術後2週,最佳矯正視力明顯提高,眼內散射明顯減小,術後視覺質量顯著提高.

Objective To evaluate the intraocular scatter after Nd∶YAG laser posterior capsulotomy and analyze visual quality based on double-pass system.Methods A prospective comparative study.Forty-six eyes of 42 consecutive pseudophakic patients with clinically observable posterior capsule opacification (fibroelastic type,The Ⅱ degree and under),who impaired the visual acuity severely,and scheduled to have Nd∶YAG laser posterior capsulotomy at our clinic,were included in this study.Before and two weeks after Nd∶YAG laser posterior capsulotomy,fully mydriatic,the BCVA was determined,using slit-lamp digital camera and combined with the Image Pro plus6.0 software to calculate the diameter of the laser drill hole.The OSI,OVs,SR,MTF value were measured at the 4mm diameter of the pupil by OQAS system.Results Significant improvement in visual acuity was observed after Nd∶YAG laser posterior capsulotomy,mean logMAR visual acuity 0.541 to 0.137.Two weeks after the procedure,significant decreases in OSI (t =16.818,P ＜0.05),after (3.263±2.118) to before (12.148±3.511),significantly increased in SR,MTF,OVs value (P ＜0.05).Conclusions After Nd∶YAG laser posterior capsulotomy,the BCVA is improved and the intraocular scatter is decreased,the visual quality is significantly improved.
