摘要
目的探讨在最高屈光度的子午线做白内障超声乳化切口联合对侧弧形角膜切开术对矫正白内障患者原有散光的疗效。方法 23例(28只眼)术前散光(-1.50～-4.15 D)的白内障患者在角膜地形图指导下,在最高屈光度的子午线做白内障超声乳化切口联合对侧弧形角膜切开术,分析术后的裸眼视力和矫正原有散光的效果。结果角膜地形图显示该术式可使术前(-2.36±1.25)D 的散光降为术后3个月(-0.58±0.71)D的散光。结论最高屈光度子午线做白内障超声乳化切口联合弧形角膜切开术对原存有-1.50～-4.15 D 的散光矫正疗效好,该术式是屈光性白内障超声乳化术散光矫正较有效的术式。
Objective To analysis the clinical result of preexisting corneal astigmatism with phacoemulcification incision on the steepest meridian combining arcutate keratotomy on the opposite side. Methods The incision of 23 cataract patients （ 28 eyes ） with preexisting corneal astigmatism （ - 1.50 ～ - 4.15Diopter ） was directed by corneal topography. The incision of phacoemulcification was performed on the steepest meridian and areutate keratotomy was performed on the opposite side. The surgical Results and the change of astigmatism were analysesed postoperatively. Results Corneal topography showed tht this operation can reduced the astigmatism from-2.36 ± 1.25 diopters preoperatively to -0.58 ±0.71 diopters three months after surgery. Conclusion It had a good surgical result of phacoemulsification incision on the steepest meridian combining arcutate keratotomy on the opposite side for preexisting corneal astigmatism from - 1.50 diopter to - 4. 15 diopter.This procedure was the effect Methods to correct the astigmatism of refractive phacoemulsification.
