This Is the Best Auto-refractor Keratometer for Optometrists

Retinoscopy and baseline refraction was the go-to techniques for eye diagnosis and description. Still, thanks to technological advancements, there are better devices that aren’t just easy to use but guarantee precise prescriptions.

The innovations are a big plus to optometrists because the eyes are the most complicated organs. Your eyes are full of intricately clustered blood vessels, nerves, soft tissues, and muscles that work in tandem to make the most important sense of all the five senses.

You need your sight for just about everything hence the need for perfect or almost perfect vision. Because of the need for perfection, optometrists are looking to determine the most precise prescription needed for 20/20 vision. This is where the auto-refractor/ keratometer comes in.



What is an Auto-refractor Keratometer?

This is the device used to determine the prescription of an eye. It measures how light is affected as it travels through your eyeball, providing the best baseline for an ophthalmologist to ascertain the correct contact lens or eyeglass prescription.

Auto-refractors are gaining popularity because they are quick to use, and they are also painless. It also offers more data compared to a retinoscope.

At the same time, there are portable auto-refractors that make it easy for you to take your practice wherever you are.

How does an auto-refractor work?

The auto-refractor shines light into the eye, and then it measures how the light changes as it bounces off the ocular fundus (the back of the eye). A patient is shown an image that moves in and out of focus. In the process, the auto-refractor takes the measurements of the reflections to determine when the eye is perfectly focused.

Once the figures are put together, the optometrist will know the level of correction required for the patient’s vision to be at its best.

The best Auto-refractor Keratometer help in determining the shape of the cornea aside from giving the correct prescription. Determining the shape of the cornea is important in diagnosing conditions like astigmatism and corneal distortion.

Thanks to the versatility of an autorefractor keratometer, different companies have come up with their unique autorefractors.
