Abstract

Objective: This study aims to examine the characteristics and influencing factors of crystalline lens tilt and decentration in ultra-high myopic cataract patients, as measured by the CASIA2.

Methods and analysis: 60 eyes scheduled for cataract surgery with an axial length (AL) ≥ 28 mm were included. The IOLMaster700 was utilized to measure AL and the white-to-white (WTW) distance. The CASIA2 was employed to measure front curvature radius (FCR), crystalline lens tilt, and crystalline lens decentration. The relationships between lens tilt, decentration, and related factors were evaluated.

Results: The degree of lens tilt was 4.62 ± 2.44°, and the decentration was 0.20 (Q1 0.13, Q3 0.28) mm. Among the 60 eyes, 11 (18.3%) had a tilt ≥7°, and 6 (10%) had a decentratiolens tilt ≥7° (P = 0.038, P = 0.018). Eyes with AL >30.00 mm and FCR <8.45 mm had a higher degree of lens tilt. Additionally, a tilt ≥7° was associated with a greater decentration (P = 0.032), n.

Conclusion: Preoperative crystalline lenses in eyes with ultra-high myopia and cataract exhibit certain degrees of tilt and decentration. An AL >30 mm is a risk factor for a lens tilt ≥7° and an decentration ≥0.4 mm. An FCR <8.45 mm is a risk factor for increased lens tilt, and a tilt ≥7° is a risk factor for increased lens decentrati ≥ 0.4 mm. An increase in AL and FCR <8.45 mm were risk factors for a and eyes with AL >30.00 mm had a higher degree of decentration (P = 0.005).

白内障超高度近视患者晶状体的倾斜和分散及其影响因素:基于 CASIA2 的研究"。
研究目的本研究旨在通过 CASIA2 测量超高度近视白内障患者晶状体倾斜和分散的特征及影响因素。方法与分析:纳入 60 只轴向长度(AL)≥ 28 mm、计划接受白内障手术的眼睛。使用 IOLMaster700 测量 AL 和白-白(WTW)距离。CASIA2 用于测量前曲率半径 (FCR)、晶状体倾斜度和晶状体分散度。对晶状体倾斜度、分散度和相关因素之间的关系进行了评估:晶状体倾斜度为 4.62 ± 2.44°,分散度为 0.20(Q1 0.13,Q3 0.28)mm。在 60 只眼睛中,11 只(18.3%)的倾斜度≥7°,6 只(10%)的散光倾斜度≥7°(P = 0.038,P = 0.018)。AL>30.00毫米且FCR P = 0.032),n.结论:超高度近视和白内障患者的术前晶状体会出现一定程度的倾斜和分散。AL>30毫米是晶状体倾斜≥7°和散光≥0.4毫米的风险因素。FCR 为 30.00 mm 的人有更高的偏斜度(P = 0.005)。
