方法：随机选择白内障囊内摘除术后患者48例50眼，根据角膜曲率计检查结果以角膜最大屈光力径线方向为中心做巩膜隧道主切口并在主切口的对侧做角膜弧形切开辅助切口，行虹膜夹型人工晶状体植入术。分别测量术前、术后不同时期的角膜散光及裸视视力。

结果：术前、术后3d； 1，3，6，12mo的平均角膜散光分别为+3.18±0.68，-1.56±0.73，+0.87±0.51，+1.21±0.70，+1.33±0.68，+1.48±0.48D； 术后3d； 1，3，6，12mo的裸眼视力分别为0.5±0.38，0.56±0.23，0.55±0.24，0.52±0.28，0.51±0.25。

结论：Ⅱ期人工晶状体植入联合角膜弧形切开术有利于提高术后裸眼视力并降低白内障囊内摘除术后无晶状体眼术前角膜散光，并且具有操作简单、手术损伤小、费用低廉等优点，适合在白内障囊内摘除术后的无晶状体眼手术矫正视力中应用。

METHODS: For demonstration, 48 postoperative patients(50 eyes)receiving the intracapsular cataract extraction were gathered up. Each patient received a scleral tunnel major incision along the radial line of the maximum corneal refractive power determined by a cornea curvimeter, and a arcuate keratotomy was made opposite to the major one; through the major incision an iris-claw intraocular lens is implanted. Each patient was measured for their corneal astigmatism and uncorrected visual acuity before and after the surgery.

RESULTS: The results suggested the average corneal astigmatism before the surgery and that 3d, 1, 3, 6 and 12mo after the surgery as +3.18±0.68, -1.56±0.73, +0.87±0.51, +1.21±0.70, +1.33±0.68 and +1.48±0.48 respectively. The uncorrected visual acuities 3d, 1, 3, 6 and 12mo after the surgery are 0.5±0.38, 0.56±0.23, 0.55±0.24, 0.52±0.28 and 0.51±0.25 respectively.

CONCLUSION: Phase-II intraocular lens implantation witharcuate keratotomy is helpful to improve the postoperative visual acuity and reduce preoperative corneal astigmatism after the intracapsular cataract extraction aphakic eyes, It is also a low-cost surgery, and easy to perform, with minor surgical injuries, particularly available for surgical visual acuity correction of the aphakic eye receiving intracapsular cataract extraction.
