CARDENAS DIAZ, Taimí et al. Principles for the intraocular lens power calculation after corneal refractive surgery. Rev Cubana Oftalmol [online]. 2016, vol.29, n.1. ISSN 0864-2176.

It is considered that approximately one million or more patients undergo refractive surgery every year. Due to aging, the number of patients with cataract, who had previously undergone refractive surgery, is increasingly higher. The inaccurate calculation of the dioptric power of the lens to be implanted is also a growing significant problem and thus the refractive surprise. This is a much more complex situation since two error sources exist: the incorrect prediction of the effective position of the lens based on the formula and the wrong determination of the corneal power through keratometry. The correction of these two factors will allow making a suitable power calculation. Hence the motivation for updated search of several articles published in the last ten years, with the objective of describing the principles for intraocular lens power calculation after corneal refractive surgery. The Infomed platform, mainly the Virtual Library of Health, was fully used.

Keywords : corneal refractive surgery; corneal power; intraocular lens power calculation.
