If a patient comes in for a keratometry reading, a gonioscopy, and instillation of eye drops, the keratometry reading should precede all the other treatments or examinations. The reason for this is that a gonioscopy and the eye drops may compromise the surface of the cornea, and therefore result in faulty measurements.
