Kimura platinum spatula is designed to obtain specimens for cultures from a corneal ulcer. This spatula is made of platinum metal. It is used to gently scrape and discard any necrotic tissue and debris surrounding the ulcer.

Kinetic Microplate Reader is an instrument to provide kinetic reading capability, permitting researchers to monitor and automatically analyze enzyme kinetics in a microplate.

Keratoconus contact lens is used to manage keratoconus. Keratoconus patients usually cannot obtain adequate vision with glasses and therefore the need for contact lenses. The keratoconus contact lens eliminates the irregularity of the cornea and acts as a new cornea for the keratoconus patient.

A keratometer is a diagnostic instrument used for measuring the curvature of the anterior surface of the cornea, particularly for assessing the extent and axis of astigmatism. It measures the central 3 mm of the cornea, which generally behaves like a sphere or a spherocylinder. A keratometer in relation to the cornea is just like an object in front of a convex reflecting mirror. Like in a convex reflecting surface, the image is located posterior to the cornea. The cornea behaves as a convex reflecting mirror and the mires of the keratometer are the objects. The radius of curvature of the cornea's anterior surface determines the size of the image.
