An overview of intraocular lens power calculation / 医学研究生学报

ABSTRACT

Cataract surgery is now often referred to as refractive surgery.It has come into the focus in recent years to choose the intraocular lens of appropriate power so as to achieve the expected postoperative refraction.Two main factors influence the measurement of intraocular lens power(IOL),the IOL power calculation formula and biological measurement of the ocular.The achievement of expected surgical outcome depends on the selection of the IOL power calculation formula and biological measurement instrument that suit the intraocular lens the specific patient.The article presents an overview of IOL power calculation with a focus on the above two aspects.
