ABSTRACT

Introduction: to obtain satisfactory results in the implant of intraocular lens, a previous study to the cataract surgery and to the correct calculation of the lens is required.
Objective: to determine the refractive results of this surgery by means of the biometrical calculation.
Methods: a descriptive and prospective study of 149 cataract operated patients was carried out in the Ophthalmology Center in the Venezuelan state of Apure, from January to April, 2014.
Results: feminine sex (61.7%) and the age group 60-69 years (41.6%) prevailed. The keratometry values fluctuated between 43-44 diopters (67.0%) and the axial longitude was of 22-24 mm (70.5%). The highest percentage in the operated eyes corresponded to those corrected with the implanted intraocular lens (79.2%).
Conclusions: the refractive results of the surgically treated patients demonstrated the importance of the calculation obtained from the intraocular lens previous to the cataract extraction.
