ABSTRACT

Objective: To characterize the behavior of the intraocular lens calculation through ultrasound biometrics.
Methods: A prospective and descriptive study was conducted in a group of patients whose cataract was surgically treated with intraocular lens implantation by means of Blumental technique at the cataract service of "Enrique Cabrera" ophthalmological center. The sample was made up of 160 eyes. The studied variables included refractive surprise, age, axial length and keratometric average according to refractive result, dioptric power of the lens and spheral component by age.
Results: The main results were 78.7% of patients did not present lens power calculation errors, most of them were 60 years-old and over, the axial length range of 22 to 24.4(67.5%) prevailed, the keratometric average was 43 to 44.9 (64.3%), the dioptric power of the lens ranged +20 to +23 dioptries (48.2%) and the spheral component yielded 0.00 and+/- 1.00 dioptries (78.8%).
Conclusions: It is considered that ultrasound biometrics is suitable for a correct lens calculation.
