Ophthalmic Prism Bar

Ophthalmic Prism Bars are a type of ophthalmic instrument used in eye care. They are part of the supply class Ophthalmic Instruments, Equipment, and Supplies, which falls under the supply group Medical, Dental, and Veterinary Equipment and Supplies.

Prism bars are used to measure and correct eye alignment issues, specifically related to binocular vision and strabismus (misalignment of the eyes). They consist of a set of prisms with different powers and orientations, mounted on a bar or handle.

During an eye examination, an ophthalmologist or optometrist may use a prism bar to assess the patient's eye alignment and determine the appropriate prism power needed to correct any deviations. The prism bar is placed in front of the patient's eyes, and the doctor observes how the prisms affect the patient's vision and eye alignment.

By using different prisms and observing the resulting changes in eye alignment, the doctor can diagnose and treat conditions such as strabismus, amblyopia (lazy eye), and other binocular vision disorders. The prism bar allows for precise measurement and adjustment of the prism power needed to align the eyes properly.

Overall, ophthalmic prism bars are essential tools in the field of ophthalmology and optometry, helping eye care professionals diagnose and correct eye alignment issues for their patients.
