摘要: 术前角膜散光是影响屈光性白内障手术效果的重要因素。散光矫正型人工晶状体(Toric IOL)植入术是目前临床上矫正白内障术前散光的主要方式。Toric IOL的不同材料和形状以及高度近视长眼轴均会影响其在囊袋内的稳定性。准分子激光屈光手术可精准矫正白内障术后的残存散光,但因为价格和二次手术等问题在临床未得到广泛应用。在角膜陡峭轴向上做白内障超声乳化手术切口矫正散光不会增加额外的风险,但矫正幅度有限。弧形角膜切开术简便易行,联合飞秒激光能进一步提高矫正的精确性,有较的临床应用前景。(国际眼科纵览,2022, 46:430-436)

Abstract: Corneal astigmatism is an important factor affecting the efficacy of refractive cataract surgery. Astigmatism correction intraocular lens (Toric IOL) implantation is the main way to correct cataract astigmatism in clinic. Different materials and shapes of Toric IOL and long eye axis of high myopia will affect the stability of IOL in the capsule bag. Refractive excimer laser surgery can accurately correct residual astigmatism after cataract surgery, but it has not been widely used in clinic because of price and secondary surgery. Cataract surgical incisions on the steep axial of the cornea to correct astigmatism does not increase the additional risk, but the correction range is limited. Arcuate keratotomy is simple and easy, combined with femtosecond laser can further improve the accuracy of correction, which has a great prospect of clinical application.(Int Rev Ophthalmol, 2022, 46: 430-436)
