目的：分析白内障手术候选人的眼部生物特征参数。

方法：横断面研究。纳入2017-01/2021-09就诊于伊朗德黑兰Farabi眼科医院的4 607例白内障患者(4 607眼)。使用IOLMaster 700 评估眼轴(AL)、角膜曲率(Kf、Ks、Km)、前房深度(ACD)。根据AL分为22 mm25 mm组，根据ACD分为3.00 mm3.60 mm组。

结果：患者平均年龄60.3±14.1(8-95)岁，女2 243例(48.69%)，男2 364例(51.31%)。AL、ACD 和平均角膜曲率范围分别为23.1-23.4 mm、3.1-3.2 mm和44.50-45.00 D。AL>25 mm组ACD平均值显著高于22 mm≤AL≤25 mm组和22 mmP<0.001)。ACD>3.60 mm组的平均AL显著高于3.00 mmP<0.001)。3.00 mm25 mm组的Kf、Ks、Km均值显著高于ACD>3.60 mm组和22 mmP<0.001)。

结论：AL长的白内障患者ACD更深，角膜更平坦； AL短的患者ACD较浅，角膜较陡。此外，深ACD患者的AL较长，角膜较平坦，浅ACD患者的AL较低，角膜较陡。

METHODS: This cross-sectional study was conducted on 4 607 cataract patients(4 607 eyes)in Farabi Eye Hospital, Tehran, Iran from January 2017 to September 2021. Axial length(AL), keratometry(Kf, Ks and Km), and anterior chamber depth(ACD)were assessed using IOLMaster 700. All eyes were categorized into three groups based on AL: short eyes(22 mm25 mm)and ACD as follows: low(3.00 mm3.60 mm).

RESULTS: The mean age of patients was 60.3±14.1(range 8-95)years \〖2 243(48.69%)female and 2 364(51.31%)male\〗. The AL, ACD and mean keratometry ranges were 23.1 to 23.4 mm, 3.1 to 3.2 mm and 44.50 to 45.00 diopter(D), respectively. The mean amount of ACD in the long eyes group was significantly higher than the normal and short eyes group(P<0.001). The mean AL in the high ACD group was significantly higher than low and normal ACD patients(P<0.001). But the mean of Kf, Ks and Km in the low ACD and long eyes group was significantly higher than in high ACD and short AL groups(P<0.001).

CONCLUSION: Those candidates with long eyes had deeper ACD with flatter cornea; while short eyes had shallower ACD with steeper cornea. Also, patients with high ACD had longer AL with flatter cornea, and patients with low ACD had lower AL with steeper cornea.
