Summary

A 29-year-old woman presented with symptoms of gradual, progressive, painless diminution of vision in both eyes for past 8–10 years. On examination, uncorrected visual acuity was 20/60 in the right eye and 20/126 in the left eye. Anterior segment examination was essentially normal except for a conical protrusion in the pupillary axis of the anterior lens capsule with a clear underlying lens. During surgery, central protruded fragile lens capsule was meticulously handled to create well-centered continuous curvilinear capsulorhexis by using paediatric rhexis forceps. Histopathology of excised capsule showed markedly thinned lens capsule with normal epithelium. Electron microscopy of the anterior lens capsule showed multiple linear and irregular zones of dehiscence. Few of these had fibrillar, irregular electron-dense material and vacuoles; and adjacent cells were irregular suggestive of Alport syndrome. Postoperative course was uneventful and visual acuity improved to 20/20 unaided. Clear lens extraction is an effective means of rehabilitating visually symptomatic anterior lenticonus of Alport syndrome.
