CHANGES OF THE CORNEA IN PATIENTS WITH CATARACT SURGERY PLUS INTRAOCULAR LENS IMPLANTATION AND PRIOR REFRACTIVE SURGERY: AN EXPLORATORY REVIEW

Abstract

Introduction: Optical aberrations are imperfections of an optical system that produce defective images and prevent the reproduction of a clear and exact copy of the fixation object. Objective: Synthesize the available evidence on changes in post cataract surgery with intraocular lens implantation and previous refractive surgery. Methodology: an exploratory literature review of observational studies was carried out in order to identify, characterize and summarize the available evidence on the prevalence of changes in the cornea after cataract surgery with intraocular implant and previous refractive surgery. Results: 9 studies were selected that added a total of 402 users intervening 608 eyes, that is, an average of 1.51 eyes per patient, the average age was 51 ± 19.4 years, with a higher frequency of women, use of standard intraocular lens, acri.smart and colamer, phacoemulsification surgery and micro incision (MICS), finding greater change in third order aberrations especially trefoil. Conclusion: the results of the body of evidence showed that a surgery with an incision equal to or less than 2.0 mm induces slight changes in the aberration of the total cornea and better optical results in the patient, including shorter recovery time and patient satisfaction. In addition, the location of the incision plays an important role in the change of corneal aberrations.
