白内障术前眼球生物学参数测量和应用专家共识(2023)

Consensus for measurement and application of ocular biometric parameters before cataract surgery(2023)

白内障是全球主要的可治疗性致盲眼病, 目前手术摘除混浊晶状体并植入人工晶状体(IOL)是治疗白内障的主要方法, IOL屈光力的准确计算是提高术眼术后视觉质量的关键, 其计算涉及术眼术前眼球生物学参数的准确测量。白内障术前应重点关注眼球生物学参数的测量和应用, 主要包括精准的眼球生物学参数测量设备的选择和IOL屈光力计算公式的选择等。为了更好地满足术眼术后视觉质量和生活质量的需求, 本专家共识依据国际上的重要文献和循证证据对白内障术前眼球生物学测量参数的选择和测量方法提出推荐意见, 既包括传统的眼轴长度、角膜曲率、前房深度、晶状体厚度、角膜直径及中央角膜厚度等眼球结构参数, 还纳入了Kappa角、Alpha角及波前像差等视光学参数。本共识同时还推荐了IOL屈光力计算公式需要的参数, 旨在规范临床医生对白内障患者实施白内障手术术前眼球生物学测量参数的选择、测量和应用, 从而提高白内障手术后的屈光效果和视觉质量。

Cataract is the leading cause of treatable blindness worldwide.Currently,surgical removal of the opaque lens and implantation of an intraocular lens(IOL)is the primary method for treating cataracts.Accurate calculation of IOL power is crucial for improving postoperative visual quality.IOL power calculation requires accurate measurement of preoperative ocular biometric parameters.Preoperative assessment and application of ocular biometric parameters,including the selection of accurate measurement devices and IOL power calculation formulas,should be emphasized in cataract cases.To better meet the needs of visual quality and quality of life of patients after surgery,this consensus provides recommendations based on important international literature and evidence-based research regarding the selection and measurement of ocular biometric parameters before cataract surgery.These recommendations include traditional ocular structural parameters such as axial length,corneal curvature,anterior chamber depth,lens thickness,corneal diameter,and central corneal thickness,as well as optical parameters including kappa angle,alpha angle,and wavefront aberrations.In addition,this consensus recommends the parameters required for IOL power calculation formulas.The goal of this consensus is to standardize the selection,measurement,and use of ocular biometric parameters in clinical practitioners before cataract surgery,thereby improving refractive outcomes and visual quality after cataract surgery.
