ABSTRACT

Introduction: Myopia is an ametropia with high prevalence rate, so it is very important to have safe, stable and predictable treatments for precise correction.
Objective: To evaluate residual refractive errors and their associated factors in patients with high myopia with a phacoemulsification surgical technique in the most curved meridian.
Methods: Prospective descriptive study in 31 patients (44 eyes), with high myopia, with intraocular lens implantation and candidates for phacoemulsification surgery in the Ophthalmology Service at Hermanos Ameijeiras Clinical Surgical Hospital from January 2018 to January 2020. The study variables were sphere, astigmatism, axial length, and objective and subjective satisfaction.
Results: The mean age was 51.8 years and the females predominated. The sphere and cylinder in both eyes showed significant differences (p <0.001) between the pre and postoperative means. Axial length and preoperative astigmatism influenced the postoperative sphere value as independent variables. Most of the patients expressed satisfaction with the postoperative visual result.
Conclusions: The associated factors that independently influenced the postoperative sphere value were axial length and preoperative astigmatism. The residual spherical defect was in the optimal range, which generated high degree of satisfaction in the patients.
