Bilateral phacoemulsification and toric extended depth of focus intraocular lens implantation in Alport's syndromes

Abstract

Alport syndrome is a hereditary disorder characterized by sensorineural deafness, renal disease, and ocular abnormalities, including anterior lenticonus with high refractive errors. We report a case of Alport's syndrome with bilateral anterior lenticonus that was submitted to phacoemulsification and toric extended depth of focus (EDOF) intraocular lens (IOL) implantation. A 49-year-old male patient presented with progressive bilateral visual loss for 10 years. His past medical history included a diagnosis of Alport's syndrome, with renal transplantation 20 years ago. The best-corrected visual acuity was 20/80 in the right eye and 20/63 in the left eye. Examination showed anterior lenticonus and anterior subcapsular opacities. Phacoemulsification and toric EDOF-IOL implantation were performed in both eyes. Capsulorhexis was challenging because of a highly elastic anterior capsule, which was aided by the use of a viscoadaptive ophthalmic viscosurgical device. The postoperative period was uneventful, with good refractive and visual outcomes.
