CARDENAS DIAZ, Taimi et al. Antecedents and current status of the use of phakic lenses for ametropia correction. Rev Cubana Oftalmol [online]. 2018, vol.31, n.2, pp. 1-13. ISSN 1561-3070.

Refractive surgery is a subspecialty comprising all the surgical procedures aimed at modifying ocular refraction in its various ametropias. Its aim is to improve uncorrected visual acuity, reducing dependence on eyeglasses or contact lenses. There are different options, such as keratorefractive procedures and intraocular lens implantation, with removal of the crystalline lens (pseudophakia) or in phakic eyes, between the cornea and the crystalline lens. A combination of more than one procedure is sometimes required. Phakic intraocular lenses are divided into two groups: anterior chamber lenses, including the angle-supported and iris fixation types, and posterior chamber lenses, performed by sulcus implantation. Unlike laser corneal or crystalline lens surgery, correction of moderate-to-severe ametropia using these lenses makes it possible to retain accommodation, and provides better optical quality, a certain reversibility of the procedure, and the possibility of correcting residual refractive defects by minimum corneal surgery. Hence the motivation to conduct an updated search in various published papers with the purpose of describing all the types of phakic intraocular lenses and their advantages. Use was made of the Infomed platform, particularly the Virtual Health Library with all its search engines.
