Caption: Optician using a keratometer to measure the radius of curvature of the patient's cornea. A reading is taken by superimposing two patterns projected onto the cornea. Accurate measurements of the curvature are needed when fitting contact lenses, and when investigating disorders such as astigmatism (ab- normal curvature: surface resembles an egg rather than a sphere) and glaucoma (excessive pressure of internal fluid).
