Changes In Corneal Aberrations In Patients With Cataract Surgery With Toric Lens Implant: An Exploratory Review

IntroductionThe cataract is one of the main causes of visual alterations, which is normally treated with surgery since it improves the visual acuity of the patients, the object of the present investigation is to synthesize evidence on how the surgical intervention affects or changes the corneal aberrations. Methodologyconducted an exploratory review of the literature, observational studies on changes in corneal aberrations after cataract surgery with toric lens implant, using Pubmed, Google Scholar, Lilacs, Scopus, and Science Direct, searching and selecting articles from blindly and independently, following the PRISMA methodology. ResultsThe body of evidence selected was 4 articles published in a 6-year window, between 2011 and 2016. The average age of the surgically operated population was 65.3 {+/-} 7.7 years, while the proportion according to sex there was a similar and greater change in corneal aberrations due to coma and trefoil. Conclusionssurgery with an incision equal to or less than 2.2 mm induces slight changes in the aberration of the total cornea, which increase before in eyes with a high pre-existence of corneal astigmatism and it is independent if the lens is toric or not.
