Evisceration – removal of the iris, lens, and internal eye contents, but with the sclera and attached extraocular muscles left behind; Enucleation of the eye – removal of the eyeball, but with the eyelids and adjacent structures of the eye socket remaining.

Iridectomy - Removal of the affected piece of the iris; Choroidectomy - Removal of the choroid layer (the vascular tissue sandwiched between the sclera and the retina)
(H15.0) Scleritis — a painful inflammation of the sclera (H16) Keratitis — inflammation of the cornea (H16.0) Corneal ulcer / Corneal abrasion — loss of the surface epithelial layer of the eye's cornea (H16.1) Snow blindness / Arc eye — a painful condition caused by exposure of unprotected eyes to bright light
