景深延长型人工晶状体对散光包容性的研究进展

Advances in the inclusiveness of extended depth of focus intraocular lens for astigmatism

摘要:

自1949年Harold Ridley植入了第一枚人工晶状体以来，到景深延长型人工晶状体(EDOF IOL)在临床的广泛应用，人工晶状体(IOL)一直在不断更新与发展，旨在为患者提供良好的术后视觉质量。而残余散光是影响白内障患者术后视觉质量的重要因素之一，35%-40%白内障患者散光达到1.00 D，19%-22%白内障患者散光达到1.50 D。因此，了解EDOF IOL对散光的包容性，从而为患者选择合适的IOL显得十分重要。文章总结了不同类型EDOF IOL对散光的包容性及优缺点，期望在为不同残余散光的患者选择EDOF IOL时提供参考。

Abstract:

Since the first intraocular lens(IOL)was implanted by Harold Ridley in 1949 and the widespread use of depth-of-focus extended intraocular lens(EDOF IOL)clinically, the IOL has been constantly updated and developed, aiming to provide patients with good postoperative visual quality. The residual astigmatism is one of the important factors affecting the postoperative visual quality of cataract patients, 35%-40% of cataract patients have astigmatism of 1.00 D, and 19%-22% have astigmatism of 1.50 D. Therefore, it is important to understand the inclusiveness of EDOF IOL for astigmatism, so that the right IOL can be selected for the patient. This article summarizes the inclusiveness of different types of EDOF IOL for astigmatism and their advantages and disadvantages, with the expectation that it will provide a reference in selecting EDOF IOL for patients with different residual astigmatism.
