To report results of intrascleral fixation of 3-piece IOL without the help of suture and glue.
Study included intrascleral fixation of haptic in 50 eyes by T-fixation technique. Preoperative and postoperative visual acuity, slit lamp and fundus examination, applanation tonometry, keratometry, biometry, optical coherence tomography, Scheimpflug imaging were done for extensive evaluation. Qualitative and quantitative data were summarized in the form of proportion and mean and standard deviation, respectively. The significance of difference was measured by Chi-square test or unpaired t-test or ANOVA whichever is appropriate. P < 0.05 was considered as statistically significant.
There was one case in which haptic broke during handshake maneuver and another IOL was required. Postoperative complications included corneal edema (4%), increased intraocular pressure (6%), cystoid macular edema (2%), decentration (4%), and dislocation (2%), which were all managed to the level of good visual recovery. There was no significant change in corneal astigmatism. There was significant change found in best-corrected visual acuity and uncorrected visual acuity after surgery.
This modified technique seems to be a good alternative in IOL implantation in eyes with deficient capsules in view of the decrease in the learning time and surgical time and risk for complications.
报告在不借助缝线和胶水的情况下进行三片式人工晶状体巩膜内固定的结果。
研究纳入50只眼采用T形固定技术进行襻的巩膜内固定。术前行视力检查、裂隙灯及眼底检查、压平眼压测量、角膜曲率测量、生物测量、光学相干断层扫描、眼前节分析系统成像,术后进行上述检查以进行全面评估。定性和定量数据分别以比例以及均值和标准差的形式汇总。差异的显著性采用卡方检验、非配对t检验或方差分析(视情况而定)进行测量。P<0.05被认为具有统计学显著性。
有1例在握手动作中襻断裂,需要植入另一枚人工晶状体。术后并发症包括角膜水肿(4%)、眼压升高(6%)、黄斑囊样水肿(2%)、偏心(4%)和脱位(2%),所有这些并发症均得到处理,视力恢复良好。角膜散光无显著变化。术后最佳矫正视力和未矫正视力有显著变化。
鉴于学习时间、手术时间和并发症风险的降低,这种改良技术似乎是囊袋不足的眼中人工晶状体植入的良好替代方法。
