Abstract
This paper describes the intraoperative refraction for intraocular lens (IOL) power calculation. Report a case of a 67 year-old male patient reporting a progressive loss of visual acuity in the left eye (OS). Examination revealed best corrected visual acuity (BCVA) of 20/60 (-21,50 -4,00 X 170) related to adherence of silicone oil to the IOL optic. IOL exchange was proposed, however biometry was variable and doubtful. Intraoperative refraction confirmed the IOL power and the patient underwent uneventful IOL explantation and exchange with a three-piece acrylic IOL. After surgery, examination revealed BCVA OS of 20/30 (-1,25 -1,25 X 180). Analysis of explanted IOL confirmed adherence of silicone oil to the IOL optic. Intraoperative refraction is useful to confirm IOL power calculation.
Highlights
O presente relato tem como objetivo descrever a utilização do método refracional intraoperatório para confirmação do cálculo da lente em um paciente com indicação de substituição da lente intraocular (LIO), danificada devido à impregnação por óleo de silicone

Summary
Este relato descreve a utilização do método refracional intraoperatório para confirmação do cálculo da lente intraocular (LIO). Paciente de 67 anos com acuidade visual (AV) igual a 20/60 no olho esquerdo (OE) com correção igual a -21,50 esf -400 cil a 170 devido à LIO de silicone 3 peças impregnada por óleo de silicone. Foi realizado o cálculo intraoperatório e o paciente foi submetido à troca da LIO impregnada por uma LIO acrílica 3 peças.
