摘要
随着白内障手术技术提升,不同设计的人工晶状体面世,白内障手术逐渐趋向屈光矫正性手术,患者对视觉质量有更高的要求。角膜散光是影响患者术后视觉质量的原因之一,Toric人工晶状体植入是常用的散光矫正方式,其轴向错位是影响患者术后散光矫正效果最重要的原因。为了减少轴向错位对术后矫正效果的影响,需要重视术前的眼球生物学测量、人工晶状体度数及轴位计算、角膜标记,熟练术中的操作技巧,了解各类型人工晶状体及患者眼轴对术后人工晶状体旋转稳定性的影响。
With the improvement of cataract surgery technology and the development of design and materials of the intraocular lenses(IOL),cataract surgery is gradually becoming refractive surgery.Patients also pursue better postoperative visual experiences.However,corneal astigmatism is always the major factors affecting the postoperative visual quality.Toric IOL is a common clinical method for correcting preexisting astigmatism in patients with cataracts.Misalignment of Toric IOL is an important factor that affects the effect of astigmatism correction.In order to reduce the misalignment of Toric IOL to achieve great postoperative results,we should pay attention to ocular biometry,Toric IOL power and calculation,marking techniques before the surgery,master the standard surgical procedure,and understanding the impact of various types of Toric IOL and patients’axial length on the rotational stability postoperatively.
