KEELER Meaning and
Definition
-
Keeler is a noun that refers to a small handheld instrument used in ophthalmology and optometry to examine the interior of the eye, particularly the retinal and optic nerve areas. It consists of a handle with a light source attached, and a set of interchangeable viewing lenses. Keelers are commonly used by medical professionals to diagnose and monitor various eye conditions, such as glaucoma, macular degeneration, and diabetic retinopathy.
The instrument's handle typically contains a bulb or LED that emits a bright, focused light beam. This light is directed into the eye through the viewing lenses, allowing the examiner to illuminate and magnify specific areas of the retina for detailed inspection. By adjusting the lenses, the focus and magnification level can be altered to examine different layers of the eye. Keelers are often accompanied by accessories like filters and apertures that aid in the visualization of specific eye structures.
The word "Keeler" is derived from the name of the inventor, Charles Francis Keeler, an American physician who revolutionized ophthalmic instruments in the late 19th century. His innovative design brought portability and ease of use to eye examinations, replacing bulkier and more complex devices used at the time. Today, Keelers are widely used in clinical settings and play a vital role in the comprehensive evaluation of ocular health.
