What is an Autorefractor Keratometer?

If you've ever gone to the attention doctor's office, chances are you've seen auto refractors and keratometers and didn't even realize it. These devices are highly useful, and though they have a slightly complicated name, their function is quite practical.

So, what do these exact things do, exactly? Let's break it down. First of all, an autorefractor is a machine that will measure your prescription for glasses or contact lenses. In addition, it parses out the refractive error. It works by shining light onto your eye and measuring how the light changes when it bounces back.

This kind of popular machine is fast to utilize and causes the in-patient no pain or discomfort. In terms of the in-patient is concerned, they're just looking into a machine at a picture. This picture changes focus, and the equipment takes several measurements to calculate when the image appears on the retina.

After several measurements are taken, an average is calculated, and the prescription is formed. This is a straightforward way to find out a prescription minus the subjective part of asking someone when he or she could see letters on a graph clearly, for instance.

A keratometer is a machine that measures the cornea and its shape by shining light about it and measuring the reflection. It's also used to diagnose numerous eye problems like astigmatism and other corneal issues and make certain a correct fit for contact lenses.

Why is the autorefractor keratometer revolutionary is that it combines both of these machines into one easy-to-use device. This cuts down on error and on time needed for patient visits. In every way, this is a benefit to the attention care industry. Eye doctors could see more patients and reduce the amount of time allocated to diagnostics while patients save time at their appointments. This also dramatically reduces patient wait times and can likely make the attention doctor much less stressed.

As the autorefractor keratometer can't replace most of the tests and procedures in a watch doctor's office, it can streamline a few processes. In addition, it works to give doctors a place to begin when determining a patient's prescription. This kick-off point is coupled with traditional vision tests to produce a more accurate picture of just what a person's prescription should be. And anything that makes it likely to the attention doctor a bit easier is worth it.
