Abstract

BIANCARDI, Ana Luiza; WALSH, Aileen  and  CREMA, Armando Stefano. Intraoperative refraction for intraocular lens power calculation. Rev. bras.oftalmol. [online]. 2011, vol.70, n.2, pp.118-121. ISSN 0034-7280.  https://doi.org/10.1590/S0034-72802011000200010.

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.

Keywords : Cataract; Intraocular lens; Biometry; Case report.
