Optometrist equipment is a huge part of the trade. Every doctor requires the appropriate equipment to work. The same is true for Optometrist. However, as the profession focuses solely on eyes of humans, the tools are different.
Eye is a sensitive part of the body. Hence, doctors use painless and accurate equipment for diagnosing any eye’s health problem or check the status of eye’s health.
Optometrist Equipment – The tools used during examination of eyes’ health status
While the tools might look intimidating, they are made while keeping the eye’s in mind. It means that they are safe to use at one of the most sensitive area on the face.
Here is a list of tools that Optometrist use while diagnosing eyes.
A sustained fluid pressure inside the eyeball keeps it working. However, if the pressure increases to a certain degree, it can cause permanent damage to the optic nerve. To check the pressure of the fluids, optometrists use tonometer.
Tonometer gently touches the cornea of the eye to check the pressure. Before using the tonometer, doctors can use the numbing drops.
Also, air-puff tonometer is available in the market. It blows air on the eyes to measure the eye pressure.
The disorder of high pressure in the eye ball is called glaucoma.
2. Retinal Camera
Retinal Camera is essentially a low-powered microscope used to look at the interior surface of the eye. The specialist can use different pictures to take images of different parts of the retina clearly.
Doctors use the device to monitor the changes in the eye over time and diagnose a number of diseases.
3. VT1 Vision Screener
It is the ultimate tool to identify major visual problems. The device is light in weight, which makes it easily portable. Moreover, it is simple to use.
The device can help identify visual problems of patients of all ages. It is effective on six months old children.
VT1 Vision Screener does not require dilation of pupils and can help identify a range of eye disease.
4. Snellen Chart
It is the physical or digital chart that has alphabets in decreasing order of sizes. The optometrist places it 20 feet or 6 meter away from the reader.
At a time, reader can only use one eye to read the letters to determine the correct prescription. If the patient cannot read all the letters, the optometrist will use metal eyeglasses frame. Here, the doctor will apply different lenses till the patient is able to read all the letters.
Refractive errors were hard to judge in children, mentally-challenged, or patients physically unable to offer feedback. Retinoscope is the method for these patients.
The retinoscope has is a mirror that shines light into the eyes of the patient. The hole in the center of the device allows the device to examine the eyes and determine the refractive error correctly.
6. Specular Microscope
The innermost lining of your cornea comprises of cells layers that do not regenerate. However, they do change shape and size to fill any space left due to loss of other cells.
The loss can happen due to corneal diseases, extended or overuse of contact lens, and intraocular surgeries.
The device helps measure the endothelial cell density, helping in determining the course of action to protect the sight.
7. Slit Lamp
It is a device that offers three-dimensional view of the eye. Doctors use it to look at cornea, sclera, and iris. Different lenses between the lap and cornea can help see deeper structures like retina, optic nerve, and the area where fluid drains out.
The device can help identify several disorders, and pinpoint any foreign objects in the eye. It is also effective in finding eye problems that might have occurred due to other diseases or contact lenses.
It is another method of checking the refractive error in human eye. Here, the patient only looks into the machine and a picture moves in and out of focus.
The device identifies when the image is on the retina and takes appropriate readings. After several readings, the average of the data helps decide the prescription.
The method works best to avoid errors.
Importance of Optometrist Equipment
The new technology has enabled optometrists to identify and rectify or control eye diseases in infants and other specially-abled individuals.
Technology has been a boon for the healthcare world. These equipment help doctors do their job.
The advanced technology has made eye healthcare more accessible to the individuals of the world. Moreover, the optometrist equipment ensures that patients get proper care every time they step into the doctor’s office.
