To describe the efficiency and visual results of a new method of transconjunctival intrascleral fixation of single-piece foldable IOL using double-flanged 6/0 prolene suture.
Seventeen aphakic eyes of 17 patients without adequate capsular support were involved in this study. Lens was prepared by passing the 6/0 prolene suture in a track in the haptic of single-piece foldable IOL created by 31 g needle. The 6/0 prolene suture was retrieved through a 30 g needle transconjunctivally to outside the globe; then, IOL was implanted and a terminal bulb was created at the outer end of the prolene suture.
All cases were aphakic after complicated phacoemulsification. In 10 cases hydrophilic IOLs were used and in 7 cases hydrophobic IOLs were used. There is clear statistically significant difference between pre-UCVA and post- UCVA. Complications included suture slippage in 2 cases and prolene bulb exposure in one case. There was no significant difference in endothelial cell count and IOP before and after 3 months.
Transconjunctival intrascleral fixation of foldable single-piece IOLs is a safe efficient method for correcting aphakia.
描述一种使用双凸缘6/0普理灵缝线经结膜巩膜内固定单片可折叠人工晶状体的新方法的有效性和视觉效果。
本研究纳入17例无足够囊袋支撑的无晶状体眼患者的17只眼睛。通过31G针头在单片可折叠人工晶状体的襻上制作的通道中穿入6/0普理灵缝线来准备人工晶状体。6/0普理灵缝线经结膜通过30G针头引出至眼球外;然后,植入人工晶状体,并在普理灵缝线的外端制作一个终端球结。
所有病例均在复杂白内障超声乳化术后变为无晶状体眼。10例使用亲水性人工晶状体,7例使用疏水性人工晶状体。术前和术后最佳矫正视力之间存在明显的统计学显著差异。并发症包括2例缝线滑脱和1例普理灵球结暴露。3个月前后内皮细胞计数和眼压无显著差异。
经结膜巩膜内固定可折叠单片人工晶状体是矫正无晶状体眼的一种安全有效的方法。
