【摘要】：目的探讨以连续环行撕囊方法制作大直径前囊口在手法无缝线白内障囊外摘出术中的安全性及有效性。方法采用手法无缝线白内障囊外摘出术对五三五医院住院的1443例(1965眼)白内障患者进行手术,术中采用连续环行撕囊法制作直径7~8 mm的前囊口,对患者术中撕囊是否成功、有无后囊破裂、术后角膜水肿及视力等情况进行统计学分析,研究其手术价值。结果 1942眼(98.8%)连续撕囊成功;15眼(0.8%)囊膜瓣向周边撕裂不能挽救,留有放射状裂口1个;8眼(0.4%)因为囊膜钙化、机化等原因,无法常规撕囊,采用囊膜剪开及截囊等方法完成前囊开口。所有病例均无后囊破裂等并发症发生,并顺利植入人工晶状体。术后一过性角膜水肿36眼(1.8%),术后90 d视力0.5者1674眼(85.2%),0.3者1878眼(95.6%)。结论在手法白内障术中用连续环形撕囊方法制作大于常规直径的前囊口,使手术安全性提高,值得推广和应用。
[Abstract]:Objective to investigate the safety and efficacy of large diameter anterior capsular orifice by continuous circular capsulorhexis in extracapsular cataract extraction. Methods 1443 cases of cataract were operated with manual seamless extracapsular cataract extraction (CSCL). The anterior capsular orifice with diameter of 7 ~ 8 mm was made by continuous circular capsulorhexis during the operation. Whether or not the capsulorhexis was successful during the operation. The postoperative corneal edema and visual acuity were analyzed statistically. Results 1942 eyes (98.8 eyes) successfully tore the capsule in 15 eyes (0.8%) the tear of the capsule flap to the periphery could not be saved, and the radial fissure was left in 1 eye (0. 4 eyes) because of the calcification and organization of the capsule membrane, it was impossible to tear the capsule routinely. The opening of anterior capsule was completed by cystectomy and cystectomy. No complications such as rupture of posterior capsule were found in all cases, and intraocular lens implantation was successful. Postoperative transient corneal edema was found in 36 eyes (1.8%) and visual acuity of 1674 eyes (1674 eyes) at 90 days after operation. Conclusion the method of continuous circular capsulorhexis is used to make the anterior capsule orifice larger than the conventional diameter in the manual cataract operation, which can improve the safety of the operation and be worth popularizing and applying.
