摘要:
目的 观察白内障患者术前Alpha角的分布特点、分析相关影响因素。方法 回顾性分析我院2019年白内障患者204例(204眼),采用OPD-Scan Ⅲ测量患者Alpha角(LDist@angle)及明视Kappa角(PDist@angle)及瞳孔大小,使用OA-2000生物测量仪测量患者的眼轴、平均曲率、前房深度及晶体厚度。使用SIA矢量分析软件绘制极坐标散点图,分析右眼及左眼LDist的分布情况; 使用独立样本t检验分析不同性别、眼别间Alpha角的差异,使用Pearson相关分析其他生物测量参数对Alpha角大小的影响,线性回归分析Kappa角与Alpha角的关系。结果 LDist平均值为(0.43±0.18)mm; 双眼LDist多位于颞侧; 不同性别及眼别组间LDist比较,差异无统计学意义。LDist与眼轴、前房深度成负相关,与年龄、角膜平均曲率、晶体厚度、瞳孔大小无明显相关性。LDist与PDist大小呈线性正相关。结论 Alpha角分布比较集中稳定; Alpha角大小与眼轴、前房深度成负相关,当无法测量Alpha角时,对于短眼轴、浅前房的患者可能需慎重使用多焦点人工晶体; 当Alpha角>0.5 mm时,植入多焦点人工晶体术后发生光学干扰的可能性增加。
Abstract:
Objective To observe the distribution of kappa alpha angle before cataract surgery, analyze the relevant factors affecting it and the correlation between kappa angle and alpha angle. Methods A retrospective research was conducted.The preoperative angle alpha(LDist@angle),angle kappa(PDist@angle), and pupil size of 204 patients(204 eyes)were measured and recorded by OPD-Scan Ⅲ in 2019.The preoperative axial,mean corneal curvature,anterior chamber depth and lens thickness were measured by OA-2000.Independent-samplet tests were performed to test for significant differences in the magnitude of angle alpha preoperatively between genders and eyes.Pearson correlations were performed for correlation analysis of influence of parameters on alpha angle.Linear regression analysis was performed for the relationship between angle kappa and angle alpha. Results The mean value of LDist was(0.43 ±0.18)mm.There was no significant difference in LDist between different genders and different eyes.The distribution of LDist was mostly in the temporal side both in left and right eyes.LDist was negatively correlated with axial and anterior chamber depth.There is a linear positive correlation between PDist and LDist. Conclusion The distribution of angle alpha is centralized and stable.Age,anterior chamber depth and lens thickness have influence on and angle alpha.When angle alpha can not be measured, multifocal intraocular lens may be used cautiously for patients with short ocular axis and shallow anterior chamber.When angle alpha is greater than 0.5 mm, the possibility of optical interference after implantation of multifocal intraocular lens increases.
