Introduction: Myopia is the most common ocular condition worldwide. Various methods exist for correcting high myopia, and our focus lies on refractive extraction of the crystalline lens with intraocular lens implantation (IOL). The IOL calculation should be as accurate as possible, therefore, a systematic review was performed to compare the error in the prediction of postoperative refraction among different formulas.
Objective: To carry out an evaluation of the literature found in the main electronic databases, where the results of phacorefractive surgery in patients with high myopia are described based on the predictive error of the formulas used.
Methods: Search for information in specialized electronic information sources: PubMed, Trip Database, Cochrane Library and Science Direct. Meta-analysis of the MAE (mean absolute error) and MNE (mean numerical error) results of the selected articles was performed to estimate which formula is the most accurate for calculating the intraocular lens in eyes with high myopia.
Results: 10 articles were selected that met the eligibility and quality criteria for the systematic review, of which 7 articles were used to perform the meta-analysis of single means of MAE and 6 articles for the meta-analysis of single means of MNE, the Barrett formula Universal II obtained the lowest global values of predictive error in both meta-analyses.
Conclusions: The Barrett formula, as it obtains the most predictable results, is considered the standard formula for intraocular lens calculation in patients with high myopia.
