Abstract

Presbyopia is an age-related physiological condition that causes a gradual loss in the ability to focus on near objects, secondary to changes in zonular fibers, ciliary muscle and crystalline lens. Different surgical approaches are being pursued to surgically compensate presbyopia, such as corneal techniques or implantation of multifocal intraocular lenses (IOLs); however, their inability to restore accommodation has led to the development of single-optic positional accommodative IOLs. The axial shift, with the contraction of the ciliary muscle, of these IOLs increases the refractive power of the eye, improving the level of uncorrected near vision. Single-optic positional accommodative IOLs present few disturbances and larger ocular aberrations that improve near vision. However, reduced amplitudes of accommodation are obtained, little IOL shifts are measured and overall visual outcomes are limited.
