Abstract
Raised intraocular pressure (IOP) following penetrating keratoplasty (PKP) is the second most common cause of graft failure and an important cause of irreversible blindness. Therefore management of IOP may be required before, along with or after the patient has undergone PKP. Irreversible visual loss is seen due to optic nerve damage, and graft failure is caused by persistent rise in IOP leading to chronic corneal endothelial damage leading to corneal oedema and compromised graft clarity [1].
