This intimidating alien-looking piece of equipment helps to measure refractive errors, such as hyperopia and myopia, to help eye doctors determine the right prescription for corrective lenses (contacts and glasses). This tool is quite subjective, as the patient informs the doctor what he or she can see through a range of applied lenses. By using various lenses, the optometrist asks the patient to identify the lens that he or she can see clearer through. This helps to determine the most appropriate lenses for the eyes. So, the patient should provide the eye doctor with the most accurate information to help obtain the best corrective lenses.
Eye doctors use this handheld device for a comprehensive examination of the interior of the eye. The pupil has to be dilated for this examination to be carried out. By dilating the patient’s eye, the eye doctor can have a better view of the eye’s interior, including the structures behind it. Pupil dilation is not mandatory and the interior of the eye can still be examined without it, but it helps to provide a more comprehensive inspection.
This tool is important in measuring the eye pressure and has helped in the detection of glaucoma, one of the most common eye problems. The eye doctor uses numbing drops because the tonometer has to touch the eye. However, when the air-puff tonometer is used, there is no need for numbing drops. This tool works by measuring the production of the liquid inside the eye (aqueous humor) and the rate at which this liquid drains into the tissue near the cornea.
