Abstract

Introduction: Since the transition from extracapsular surgery to phacoemulsification, refractive outcomes of cataract surgery have been favorable.

Objective: To determine the stability of biometric parameters at different postoperative time points.

Methods: An observational-descriptive and longitudinal-prospective study was conducted at the Ocular Microsurgery Center of the Cuban Institute of Ophthalmology "Ramón Pando Ferrer." Data were collected during the follow-up period: 1, 4, 6, and 12 weeks.

Results: The sample consisted of 43 eyes of 29 patients who underwent cataract surgery using phacoemulsification. 55.2% were female. The mean age was 65.93 (SD = 10.66) years. Regarding keratometric cylinder measurements, the average decrease was one diopter in the first week, with a statistically significant decrease occurring in the sixth week (p = 0.001). Regarding corneal thickness, the highest values ​​were found in the first week and decreased significantly from the fourth week onwards (p = 0.030). No statistically significant differences were found in axial length (p = 0.424) and anterior chamber thickness (p = 0.078) during follow-up.

Conclusions: The sample was characterized by a slight predominance of females and patients in their seventies. No changes were found in axial length and anterior chamber thickness after the first postoperative week. Significant changes in keratometric cylinder stabilized at week 6. The greatest change in corneal thickness occurred in the first postoperative week compared to the preoperative period.
