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

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.
