The toric lens is a specialized, advanced form of intraocular lens (IOL) used in cataract surgery to restore vision. It is designed to correct astigmatism, an irregular curvature of the eye due to unequal refraction power in different parts of the eye.
The toric IOL is made up of two separate lens components that work together to correct astigmatism in the eye. The first component is the optical part, which focuses light and sharpens the vision. The other component is an astigmatic correcting portion that helps reduce the effect of astigmatism in the eye.
