Abstract
Intraocular lens (IOL) technology has evolved dramatically in recent years with various premium IOLs improving the visual outcome. Toric IOLs with toricity on their posterior surface are able to correct astigmatism but the results depend on the correct axis of placement. Multifocal IOLs have specialized optical properties that can divide light to bring it into focus at more than one point at the same time and are currently the most reliable lenses for attaining both distance and near vision. Accommodating IOLs uses the optic shift principle and depend on the strength of ciliary body for their action. Microincisional IOLs acts by minimizing the surgeon induced astigmatism. Light adjustable lenses allow non-invasive post-operative adjustment of the IOL’s refractive power. Aspheric IOLs reduce the spherical aberrations and provides better image quality and contrast. This is a rapidly evolving field and the future looks promising. *Himanshu Shekhar, Rajesh Sinha
