To study the implant surgery through a newly designed L-shaped sutureless scleral tunnel incision and compare the therapeutic effects of this incision with the conventional 3.2 mm scleral tunnel incisions.
Phacoemulsification was performed through a L-shaped incision with implantation of 6 mm PMMA intraocular lens (IOL) and 3.2 mm scleral tunnel incision with implantation of acrylic foldable IOL. Uncorrected visual acuity and corneal topography were examined before the operation and 1 day, 7 days, 1 month, 3 months after the operation.
From 1 day to 3 months post-operatively, there was no statistical difference between the two groups in uncorrected visual acuity, surgical induced astigmatism and axis of corneal astigmatism. The preoperative and the post-operative corneal topographies of the two groups were similar.
The therapeutic effects of the two groups are similar. In the L-shaped scleral tunnel incision group, the less expensive PMMA IOL can be used.
研究通过新设计的L形无缝合巩膜隧道切口进行植入手术，并将该切口的治疗效果与传统的3.2mm巩膜隧道切口进行比较。
通过L形切口进行超声乳化白内障吸除术并植入6mm PMMA人工晶状体（IOL），以及通过3.2mm巩膜隧道切口植入丙烯酸可折叠IOL。在手术前以及手术后1天、7天、1个月、3个月检查裸眼视力和角膜地形图。
术后1天至3个月，两组在裸眼视力、手术源性散光和角膜散光轴方面无统计学差异。两组术前和术后的角膜地形图相似。
两组的治疗效果相似。在L形巩膜隧道切口组中，可以使用成本较低的PMMA IOL。
