Acute onset of deep calcareous degeneration treated with keratoplasty procedures: Two cases report

There are two types of corneal calcium deposition, one is calcific band keratopathy and another is calcareous degeneration. We report two cases of acute onset of calcareous degeneration after using topical eye drops for their corneal wounds. The calcification in both the cases developed within 1 month. Due to the deeper stromal opacity, calcareous degeneration was impressed. In our cases, the deposits were too deep that they required keratoplasty procedures as better treatment options. One of the cases was treated with penetrating keratoplasty and another case was treated with deep anterior lamellar keratoplasty. Both of our cases had stable corneal grafts, and there were no ocular inflammation and no recurrence of calcification at least for 6 months.
