角巩膜隧道切口超声乳化白内障吸除 折叠式人工晶状体植入术临床观察

目的 探讨角巩膜隧道切口超声乳化白内障吸除折叠式人工晶状体植入术的临床疗效。方法 对86例（107只眼）老年性白内障患者,采用角膜上方膜缘后0.5mm做长约4mm角巩膜隧道切口的方法,行超声乳化白内障吸除术,同时植入丙烯酸酯类三片式折叠式人工晶状体。结果 术后1d、1周、1个月和3个月裸眼或矫正视力≥0.5者分别为62.6%、76.6%、92.5%和88.8%。结论 角巩膜隧道切口超声乳化白内障吸除折叠式人工晶状体植入术兼有巩膜隧道小切口和透明角膜小切口手术的优点,术后疗效满意。

Clinical observation of phacoemulsification with foldable intraocular lens implantation through a limbus incision

Objective To investigate the clinical therapeutic effects of phaco emulsification with foldable intraocular lens implantation through a limbus tunnel incision. Methods Eighty six patients (107 eyes) with senile cataract underwent phacoemulsification with acrylic foldable posterior chamber intraocular lens implantation through a 4 mm superior limbus tunnel incision. Results The corrected visual acuity of 0.5 or better was 62.6% at the 1st day, and 76.6%, 92.5% and 88.8% respectively at the 1st week, 1st month and 3rd month postoperatively. Conclusion Phacoemulsification with foldable intraocular lens implantation through a limbus tunnel incision has advantages of both scleral tunnel incision and clear corneal tunnel incision. The postoperative therapeutic effects are satisfactory.
