目的:探讨寻找皮质膨胀或/和液化、囊袋饱满的白色白内障简单、成功有效的撕囊方法。方法:对500眼皮质膨胀或/和液化、囊袋饱满的白色白内障,采用非染色囊袋减压撕囊方法,充分利用粘弹物质,维持正常囊袋压力,固定已松动的晶状体核,保持前房视野清晰,在无红光反射背景下,依撕囊口边缘的反光为轨迹,控制撕囊的大小和方向,顺/逆时针方向,完成连续性环形撕囊、超声乳化及后房型人工晶状体植入。结果:四象限非染色囊袋减压撕囊464眼成功完成,20眼撕囊偏离轨道,借助囊膜剪切恢复撕囊轨迹后完成环形撕囊,12眼撕囊失败改为开罐式截囊,4眼撕囊裂向赤道部波及后囊膜,做相应处理。人工晶状体准确植入囊袋内490眼,人工晶状体植入睫状沟10眼(其中4眼行人工晶状体睫状沟缝线固定术)。随访0.5a,500眼人工晶状体位置均无偏心、移位及夹持。结论:非染色囊袋减压撕囊术是皮质膨胀或/和液化、囊袋饱满的白色白内障,特殊情况下简单有效的撕囊方法。
Objective: To explore a simple, successful and effective method of capsulorhexis in search of cortical swelling and / or liquefaction, full capsular cataract. Methods: 500 eyes with cortical expansion / liquefaction and full capsular white cataract were treated with non-dyed capsulorhexis decompression and capsulorhexis method to make full use of viscoelastic material to maintain normal capsular pressure and to fix loose lens nucleus A clear vision of the anterior chamber, in the absence of red light background, according to the edge of the capsulorhexis reflective light trajectory, control the size and direction of the capsulorhexis, clockwise / anticlockwise direction, to complete the continuity of the capsulorhexis, phacoemulsification and posterior chamber artificial Lens implantation. Results: Four-quadrant non-dyed cystadenocapsular capsulorhexis was successfully completed, while 20 capsulorhexis deviated from the orbit. The capsulotomy was used to restore the capsulorhexis after the capsulorhexis was completed. Capsule, 4 eyes capsulorhexis rupture to the equator to the posterior capsule, do the appropriate treatment. The intraocular lens was accurately implanted in 490 eyes of the capsular bag and the intraocular lens was implanted in 10 eyes of the ciliary sulcus (4 eyes were ciliary sulcus suture fixation). Follow-up 0.5a, 500 intraocular lens position no eccentricity, displacement and clamping. CONCLUSIONS: Non-dyed capsulorhexis is a simple and effective capsulorhexis method for the cortical expansion and / or liquefaction and full capsular cataract.
