Abstract:With the increasing perfection and improvement of microsurgery technique in modern ophthalmology, especially the popularization of micro-incision cataract extraction and the rise of femtosecond-laser-assisted cataract extraction, the cataract extraction and intraocular lens implantation is gradually transformed from vision rehabilitation surgery into refractive surgery and people also pursue better postoperative visual experiences. However, the preoperative and postoperative corneal astigmatism is always the main factor affecting the postoperative visual effect. In recent years, the development of design and materials of the intraocular lens(IOL)provided necessary basic conditions for clinical application of the Toric IOL. The Toric IOL is primarily characterized by effective correction of cataract patients' postoperative corneal astigmatism, which results in the enhancement of patients' postoperative visual function. In this paper, the design, classification and clinical application of Toric IOL were analyzed, and current problems and prospect were discussed.
