摘　　要：目的观察小切口无缝线超声乳化人工晶状体植入术后的屈光状态,评价手术对角膜散光的影响。方法老年性白内障患者48例(67眼),行上方3.0 mm巩膜隧道式无缝线切口超声乳化人工晶状体植入术,观察手术前后的裸眼视力、矫正视力、角膜地形图。结果术后裸眼视力有所提高,术后3个月矫正视力提高显著,角膜地形图中180°径线和90°径线角膜屈光力、角膜散光度等在手术前后差异无统计学意义(P>0.05);散光轴位有所改变,逆规性散光较术前增加,循规性散光减少。结论上方3.0 mm无缝线巩膜隧道式切口超声乳化人工晶状体植入术对角膜散光影响较小,术后第1天视力即可达到稳定状态。通过对患者手术前后的角膜地形图进行对照分析,可以评价白内障手术对角膜屈光度的影响。Objective To investigate the changes in the refractive status and cornea topography after phacoemulsification （Phaco） and intraocular lens （IOL） implantation. Methods Forty-eight age-related cataract patients （67 eyes） who accepted the Phaco and IOL implantation were followed up for 3 months. The uncorrected and corrected visual acuity and corneal topography were measured before and after the sugery. Results The uncorrected and corrected visual acuity was improved after the surgery . There were no statistical differences between the average preoperative and the postoperative refractive power of horizontal corneal, refractive power of vertical corneal and corneal astigmatism respectively （P 〉 0.05 ）. The astigmntism against the rule increased while the astigmatism with the rule decreased after the operation. Conclusions Phaco and IOL implantation with 3.0mm scleral tunnel incision does little effect on cornea astigmatism. （ Chin J Ophthalmol and Otorhinolaryngol,2008 ,8 ：374-376）
