摘要
随着白内障手术技术的不断进步及患者对视觉质量要求的提高,如何减少角膜散光、提高术后视觉质量是临床研究一直探索的问题。目前存在多种矫正角膜散光的方法:角膜缘松解术、角膜切开术及准分子激光手术,但其缺乏准确度、屈光回退、结果难以预测、治疗范围有限等缺点限制了临床上的应用。而散光型人工晶状体(Toric IOL)能合理、有效及稳定地矫正角膜散光,提高患者术后裸眼视力。就Toric IOL的临床研究进展进行综述。
How to decline corneal astigmatism to improve the visual quality is an old question by the continuing improvement of the cataract operation and the request of the patients. Astigmatism can be reduced or eliminated with several techniques, including corneal relaxing incisions, limbal relaxing incisions or excimer laser keratectomy, but some deficiencies as the lack of veracity, the limit range of the treatment, hard to predict the result of the treatment and the rebounds limit its usage on clinic. Toric IOL can correct corneal astigmatism stably, reasonably and predictably. This article is the review about the progress of clinical study of Toric intraoeular lens.
