VEITIA ROVIROSA, Zucell A. et al. Usefulness of the Barrett Suite formulas for intraocular lens calculation. Rev Cubana Oftalmol [online]. 2019, vol.32, n.1  Epub June 30, 2019. ISSN 1561-3070.

Intraocular lens power calculation is a much-debated topic. General consensus has not been achieved about which is the most accurate formula. Recent years have witnessed impressive improvement in the precision of the lens to be implanted with the use of novel biometric equipment. Evolution and development of these new generations of devices provide a wide range of options for their use. A bibliographic review was conducted with the purpose of describing the Barrett Suite applications (including Universal II, True-K and toric), as well as their new uses. The review was based on a search in Infomed databases, particularly the Virtual Health Library. The benefits described in the literature include a lower risk of refraction surprises at all axial longitudes. Additionally, the lens factor used considers both the physical position and the location of the main planes of the intraocular lens, and has the lowest mean absolute prediction error among similar formulas, though the variables of this one formula are still unknown, according to the bibliography consulted.

Keywords : Intraocular lens; Barrett; toric; refractive surprise.
