SUMMARY
This case report describes the development of an acute bilateral corneal calcification 4 days after an alkali burn. At the time of the corneal calcium deposition, the patient had an acute inflammatory process of the exposed corneal stroma, and was in frequent use of artificial tears with preservatives. Serum calcium, phosphate and carbon dioxide levels were all within normal limits. We believe that the local increase in pH, secondary to the alkali burn, favored the rapid corneal calcification. Successful results were achieved with superficial keratectomy and conjunctival transplantation in both eyes and posterior corneal graft in the right eye. Histologic studies of the superficial cornea disclosed extracellular calcium deposit.
