Phacoemulsification in bilateral anterior lenticonus in Alport syndrome: A case report

To report the visual status and results of phacoemulsification cataract surgery in a young patient with Alport syndrome associated with bilateral anterior lenticonus. The milestone of this report is the use of anterior segment optical coherence tomography (AS-OCT) to confirm the central protrusion of the anterior surface of the crystalline lens.

A 23-year-old young woman presented with severe progressive visual loss in both eyes, which started several years ago.

Refractive status was indicative of high myopia with astigmatism and vision was not improved with optimal correction to better than 0.1 in the right eye and 0.2 in the left eye (visual acuities given in decimal notation). Slit-lamp examination showed transparent cornea, anterior lenticonus and posterior sub-capsular cataract in both eyes. The classical appearance of oil droplet was evident using retro-illumination on the slit lamp.

The natural lenses were replaced with intraocular lens (IOL).

An excellent refractive status achieved associated with an uncorrected distance visual acuity 0.9 and 0.8 in the right and left eye, respectively.

AS-OCT is a valuable device for confirming the budging of the anterior crystalline lens surface.
