Macular phototrauma after cataract extraction and multifocal lens implantation: case report.

PURPOSE: To report a patient who developed photic injury after cataract surgery and multifocal MF4 lens implantation

METHODS: A 41-year-old caucasian woman without antecedents of interest was subjected to left catarct surgery involving phacoemulsification with capsular sac implantation of a new type of multifocal lens. A coaxial light microscope was used for surgery. The operation was filmed and anterior pole photographs were obtained.

RESULTS: Two days after the operation, the patient noted a paracentral scotoma and hand movement visual acuity in the left eye. Indirect ophthalmoscopy revealed an oval, hyperpigmented macular lesion compatible with phototoxic maculopathy.

CONCLUSIONS: Phototoxic injury to the macula may occur after cataract extraction. Implantation of an intraocular lens is an important factor in the producion of maculopathy, on account of its light-focusing effect on the retina. This effect was probably increased in our patient by the use of a new autofocus multifocal lens.
