You may be familiar with stethoscopes and blood pressure cuffs, and you may have even heard of an otoscope, the device used to check your ears, but can you name any of the instruments used by eye doctors? Eye doctors, also known as ophthalmologist or Optometrists, use specific tools, called ophthalmic instruments, to conduct routine eye exams and diagnose conditions of the eye. Capital Ophthalmic Instrument Service specializes in the sale and repair of these devices, so we’d like to share a little more about the tools you might see at your next exam!
Better? Or worse? Better? Or Worse? Sound familiar? When an eye doctor has determined there is a problem with your vision, such as near- or farsightedness, he or she will use a phoropter to determine which lens will work best to correct the vision problem. A phoropter is special machine used to alternate different prescription strength lenses in front of your eyes. While you read the eye chart, the doctor will ask which lens is more clear for you, switching between them until your vision corrects. The eye doctor will use the readings from the machine to determine the prescription strength for your glasses or contacts.
One of the most important things an eye doctor does is inspect for eye disease or conditions that may lead to vision loss. In order to see inside the eye, your optician will apply eye drops to dilate, or open up the pupil while you sit down in front of a Slit Lamp. This ophthalmic instrument is essentially a microscope with a strong light and a place to rest your head. Placing your chin on the chin rest and your forehead against a strap stabilizes your head and makes it easier for the eye doctor to view internal structures of the eye with the brightly lit microscope.
Glaucoma, one of the most well-known eye diseases, is often linked to increased pressure within the fluid-filled eye. A Tonometer measures this internal pressure, making it one of the primary tests for this condition. While there are different types of Tonometers, one you may commonly encounter delivers a quick puff of air to painlessly determine if there is any increased pressure inside.
Ophthalmic instruments like these often look complex, and even scary if you’re unfamiliar with them. But they are essential for enabling eye doctors to see inside your eyes, determine your prescription strength, and test for conditions like glaucoma.
