What is your diagnosis?

Analysis
Anterior basement membrane dystrophy is a common corneal dystrophy that afflicts between 5-10% of the population. In this condition, there is thickening and multilayering of the basement membrane of the corneal epithelium; basal epithelial cells may become trapped within it, preventing their typical superficial migration and desquamation. In any patient who will undergo cataract surgery, this condition should be ruled out as it may affect postoperative prognosis.
This patient was diagnosed with anterior basement membrane dystrophy dystrophy with the "dot" variant being present.
