摘要
目的:应用IOL master测量白内障患者在不同眼压下的眼轴长度和角膜曲率,观察眼压高低对人工晶体度数测定的影响。方法:对2017年5月至8月就诊于青岛大学附属医院眼科,符合纳入标准的白内障患者行前瞻性研究。将87例(87眼)年龄相关性白内障患者依据眼轴长度分为短眼轴组(20例20眼),正常眼轴组(41例41眼),长眼轴组(26例26眼),均常规行白内障超声乳化吸除联合人工晶体植入术,测量患者术后不同眼压下的眼轴长度、角膜曲率,统计学分析眼压高低对眼轴长度、角膜曲率的影响。结果:随着眼压的升高,短眼轴组、正常眼轴组、长眼轴组患者术眼眼轴长度均增长,其中长眼轴组眼轴长度增长最多,正常眼轴组次之,短眼轴组增长最少。随眼压的波动,三组患者术眼角膜曲率变化无明显规律。结论:眼压升高,眼轴长度变长,角膜曲率无明显变化规律。
Purpose: To measure the axial eye length (AL) and corneal curvature (K) of cataract patients under different intraocular pressures, to evaluate the influence of intraocular pressure (IOP) on the calculation of intraocular lens (IOL). Methods: This is a prospective study enrolling 87 cataract pa-tients who have visited the Department of Ophthalmology, Affiliated Hospital of Qingdao University from May to August in 2017. 87 cases (87 eyes) age-related cataract patients were divided into 3 groups according to the axial eye length, short AEL group (AEL 26 mm) 26 cases (26 eyes). The axial eye length and corneal curvature under different intraocular pressures were measured after the phacoemulsification and intraocular lens implantation. The effects of intraocular pressure on the length of axial eye and corneal curvature were analyzed. Results: With the elevation of intraocular pressure, the axial eye length of the three groups all increased. The long AEL group changed the most, followed by the normal AEL group and the short AEL group changed the least. But the corneal curvature in three groups did not follow any obvious regular patterns. Conclusions: With the increase of intraocular pressure, the axial eye length became longer, and there was no obvious change rule on corneal curvature.
