角膜散光是白内障术后影响视力恢复的主要原因之一, 近年来随着白内障超声乳化吸除术广泛开展,因手术引起的角膜散光一直是眼科医生关注的焦点,5mm小切口白内障超声乳化吸除术后可产生较明显的散光,而3．2mm透明角膜切口白内障超声乳化吸除联合折叠人工晶状体植入因其切口小、手术便捷且术后散光小、恢复快得到众多眼科医生的青睐,但其术后角膜散光演变情况尚需进一步探讨。
Corneal astigmatism is one of the main causes of visual acuity after cataract surgery. In recent years, with the phacoemulsification aspiration of cataract has been widely carried out, due to corneal astigmatism caused by surgery has been the focus of ophthalmologists, 5mm small incision phacoemulsification After surgery can produce more obvious astigmatism, and 3.2mm clear corneal incision cataract phacoemulsification combined with foldable intraocular lens implantation because of its small incision, the operation is convenient and postoperative astigmatism small, quick recovery by many ophthalmologists of all ages, The evolution of postoperative corneal astigmatism needs further study.
