目的:探讨人工晶状体睫状沟缝合固定术在白内障囊外摘除术中囊膜破裂、外伤性白内障、晶状体脱位、玻璃体切割术后等无晶状体囊膜或囊膜缺损的患眼中的应用。方法:我院2010-04/2011-04采用后房型IOL缝线固定术完成了24例24眼,均获得满意效果。其中晶状体后囊膜破损在2个象限残存后囊膜者,以此为依托将一侧人工晶状体襻置于其上,另侧襻睫状沟缝线固定,即"一点固定法"实施了7例。因严重外伤后而无晶状体后囊者,施行两侧襻睫状沟缝线固定,即"二点固定法"实施了17例。结果:术后随访4～12(平均6)mo,复查时矫正视力0.01～1.2,视力>0.6者15眼(62.5%),视力偏低者主要为角膜瘢痕或严重外伤视网膜病变所致。二期植入者术后视力均高于术前最佳矫正视力。结论:后房型IOL睫状沟缝线固定术是无晶状体囊膜及晶状体后囊膜破裂恢复视力的首选。

AIM:To investigate the application of suture fixation of intraocular lens(IOL)implantion in posterior chamber in the following cases:posterior capsule broken in extracapsular cataract extration,injury cataract,lens dislocation and post eperative vitrectomy.METHODS:From April 2010 to April 2011,24 cases(24 eyes) used ciliary groove suture with posterior chamber type of intraocular lens and all cases acquired satisfied result.In 7 cases with two remaining quadrants posterior capsule due to lens posterior capsule damage,relying on the remaining posterior capsule,one side of the IOL loop was placed on it,the other side of the loop were implemented ciliary groove suture fixation,which was "one point fixation".Severe post-traumatic 17 cases without lens posterior capsule were implemented the ciliary groove suture fixation of both sides loops,which was "two-point fixation".RESULTS:Following up for 4-12 months(average 6 months),the BCVA was from 0.01 to 1.2 and 15 eyes’ vision were more than 0.6(62.5%).Poor vision was because of the corneal scar and injury fundal diseases.Transplanting the IOL secondarily made the vision better than pre-operation best-corrected visual acuity(BCVA).The intraocular pressure(IOP) in all eyes were normal and all had no complication.CONCLUSION:The method of suture fixation of intraocular lens implantion in posterior chamber is the best select to the lens with the posterior capsule broken or disappearance and large range ligaments loose.
