Leucomatous corneal opacity is a dense white opacity which results due to scarring of more than half of the stroma.

The iris is adherent to the back of a leucomatous ...
The stages that follow shortly after death are: Corneal opacity, "clouding" in the eyes; Pallor mortis, paleness which happens in the first 15–120 minutes after death; Livor mortis, or dependent lividity, a settling of the blood in the lower (dependent) portion of the body; Algor mortis, the reduction in body temperature following death. This ...

Transparency can be restored by putting it in a warm, well-ventilated chamber at 31 °C (88 °F, the normal temperature), allowing the fluid to leave the cornea and become transparent.
