During surgery.

The pressure created by the continual renewal of fluids within the eye. The intraocular pressure is increased in glaucoma. In acute angle-closure glaucoma, the intraocular pressure rises because the canal into which the fluid in the front part of the eye normally drains is suddenly blocked. In chronic glaucoma, there is a gradual imbalance between the production and removal (resorption) of…

An artificial lens made of plastic, silicone, acrylic or other material that is implanted in the eye during cataract surgery. Abbreviated IOL.

Unstoppable. For example, intractable diarrhea is diarrhea that can’t be stopped, even with medication, and intractable pain is pain that can’t be stopped, even with medication.

Within the cranium, the bony dome that houses and protects the brain. An intracranial hemorrhage is bleeding within the cranium due, for example, to a stroke or leakage of blood from an aneurysm in the brain. The intracranial pressure is the pressure on brain and the cerebrospinal fluid (CSF) within the cranium. Julius Caesar and his fellow Romans called the skull the “cranium” Today…
