Femtosecond-assisted keratopigmentation for functional and cosmetic restoration in essential iris atrophy.

UNLABELLED: We describe a new surgical technique of femtosecond-assisted keratopigmentation (KTP) in a 23-year-old woman with severe visual dysfunction secondary to unilateral essential iris atrophy due to the presence of iridocorneal endothelial syndrome in her left eye. The patient presented with complaints of photophobia and monocular diplopia in the affected eye. Femtosecond-assisted KTP surgery was performed in this eye. Following the procedure, the patient reported complete elimination of photophobia and diplopia, with an excellent cosmetic result. Follow-up of 12 months was unremarkable. To our knowledge, this is the first report of a severe visual function disability caused by essential iris atrophy that was corrected by a new KTP technique.
