摘　　要：目的分析研究白内障人工晶状体植入术后视力良好裸眼视力0．8—1．5者的屈光状态及其特点。方法对年龄相关性白内障常规人工晶状体植入手术后视力良好者追踪观察，定期复查角膜曲率，以自动验光仪检查屈光状态，以插片法检查最佳矫正视力。术后24周进行远距离、中距离及近距离矫正视力检查。结果有规范而详细记录的裸眼视力≥0．8的515例（515眼）中：正视175眼（33．98％），近视及近视性散光153眼（29．71％），远视及远视性散光92眼（17．86％），混合性散光95眼（18．45％）。结论白内障植入常规人工晶状体后，具有良好视力（裸眼视力0．8～1．5）的眼中，约2／3（66．02％）有散光或近视、远视，而且没有调节功能不具备全程视力。关注白内障摘出人工晶状体植入术后的屈光不正，及时调整、完善屈光状态是眼科医师应该关注的问题。Objective To analyze the refraction status and characteristics in eyes with good visual acuity（0.8 - I. 5 ） after cataract extraction and intraocular lens implantation. Methods Followed up the patients with good visual acuity after, age-related cataract surgery and implantation of intraocular lens （IOL）. The corneal curvature, refraction and best corrected visual acuity were checked in certain time. In the 24 weeks after surgery, corrected visual acuity of the patients in different distance. Results In 515 ca- ses （515 eyes） with good vision （ ≥ 0. 8 ）, emmetropia was in 175 eyes （33.98 % ）, myopia and myopic astig- matism in 153 eyes （29.71% ） , hyperopia and hyperopic astigmatism in 92 eyes （ 17.86% ） , mixed astigma- tism in 95 eyes （ 18.45 % ）. Conclusion Nearly 2/3 in the eyes with good visual acuity （0.8 - 1.5 ） after catract surgery with IOL implantation get astigmatism or myopia, hyperopia, and maintain no accommoda- tiont. The ophthalmologist should be of concern the ametropia and improve the refraction in time after cata- ract surgery with IOL implantation.
