摘　　要：目的：探讨经透明角膜隧道对高度近视白内障患者行超声乳化摘除术的可行性及手术技巧。方法：对２１６例高度近视合并白内障患者，经角膜缘隧道切口行超声乳化吸出，并植入软性或硬性人工晶体。对超声乳化能量、时间、负压及术后视力、散光及并发症进行观察。结果：采用较低能量、中度真空压力及中低档流速行超声乳化吸出，术后视力≥０．８者１４３例，≥０．５者４９例。术前近视力≥０．８者，术后远视力常较佳。术前及术后散光３．０ｍｍ切口组无统计学差异，５．５ｍｍ切口组有统计学差异。未见明显严重并发症。结论：透明角膜超声乳化联合软性或硬性人工晶体植入，是高度近视白内障较理想的手术方式。Objective:To investigate the feasibility and technique of clear corneal tunnel phacoemulsification in high myopia.Methods:216 cataract patients with high myopia underwent clear corneal tunnel phacoemulsification with foldable or nonfoldable intraocular lens(IOL) implantation.We observed the phaco energy,vacuum level and duration.Likewise,we postoperatively assessed the visual acuity(VA),astigmatism and other complications.Results:During surgery,we used low energy,medium vacuum level and low to medium outflow speed.143 patients of 216 had best corrected VA of 0 8 or better.49 patients of 216 had 0 5 or better.We found that patients having a preoperative near vision of 0 8 or better ended up with a good postoperative distant vision.Furthermore,in the 3 0mm incision group,no significant statistical difference existed between preoperative and postoperative astigmatism.But there was a significant statistical differenc betwee preoperativ and postoperative astigmatism in the 5 5mm incision group.No severe complications were recorded.Conclusion:The clear corneal tunnel phacoemulsification with implantation of foldable or nonfoldable IOL is as uitable technique for highly myopia cataract patients.
