Abstract
The present intraocular lens includes a body portion and an optic portion. A thickness of the body portion is between 0.3 to 0.98% of a thickness of the intraocular lens itself which lens includes the body portion and the optic portion, and from 0.011 and 0.015% of a length of the body portion. The thickness of the intraocular lens itself, from 0.095 and 0.192% of the length of the body portion. The diameter of the optic portion is from 0.153 and 0.7% of the length of the body portion. The optic portion can have an anterior surface having a radius of curvature of from 0.29 and 0.967% of the radius of curvature of the posterior surface of said intraocular lens. The lens is implanted by insertion into the posterior chamber of the eye to a position anterior to the natural crystalline lens of the eye. The implanted lens is effective in correcting moderate to severe forms of hypermetropia.
