[Functional rehabilitation of a patient with central opacification of the intraocular lens optic (clinical case)].

The authors present a clinical case of central opacification of the intraocular lens (IOL) optic associated with a significant uncorrectable visual acuity decrease. Due to high surgical risks of IOL exchange, corectopia was achieved through sectoral laser photomydriasis. Stable dilation of the lower nasal sector of the pupil enabled the optical zone to be shifted outside the opaque area of the IOL. As shown by the perimetry results, the visual field borders enlarged through sectoral laser photomydriasis were comparable with the topography of the asymmetrically dilated pupil.
