Vision defects present aberrations that alter visual quality, and their correct identification is essential to achieve a good result in correcting them.

Thus, aberrometry is a technique that analyzes complex light wave systems to quantify the set of optical aberrations that exist within the ocular structure.

Next, in Área Oftalmológica Avanzada We explain what aberrometry is and what it is for. 

aberrometry

What is aberrometry?

In the ocular structure there are aberrations of lower order and higher order.

The lower order aberrations are myopia, farsightedness and astigmatismthat is, vision defects that are currently relatively easy to identify and diagnose. 

On the other hand, higher order aberrations are complex alterations that also affect visual quality but, unlike the lower ones, they can only be identified through an examination called aberrometry

Aberrometry is a modern technique in ophthalmology consisting of emit light rays to the eye to analyze how they bounce off the bottom and how they come out of the eye structure again.

If the natural lenses of the eye were all symmetrical, the rays would come out as a perfect corsage. However, since they are not, it can be seen that they project in a disorderly way depending on the transparency and shape of the fabrics. 

Analysis of the way light waves leave the eye allows the ophthalmologist to determine the eye aberrations that must be corrected to improve the visual quality of the patient.

What is?

Vision, like a fingerprint, is a unique individual trait in every human being. This means that two people with the same refractive defect have a completely different vision according to ocular aberrations.

Aberrometry allows identifying the lower and upper aberrations, in addition to fully evaluating the visual quality of the patients.

Thanks to it, the doctor can define personalized refractive treatments in which not only corrects the myopia, farsightedness and / or astigmatism, but also those imperfections that intervene in the patient's vision.  

To analyze ocular aberrations, a special instrument called an aberrometer is used. This team throws a aberometric map that the ophthalmologist uses to program the excimer laser into a refractive surgery.

By way of conclusion, we can say that aberrometry is an essential test in assessing the visual quality of patients, especially in those who suffer from ocular pathology such as keratoconusirregular astigmatism Cataracts y keratitis.

Pathologies that are detected with an aberrometer

The aberrometer does not detect any particular pathology, but rather analyzes the way light waves enter, bounce and leave the eye structure to identify blemishes

Through aberrometry, it is possible to detect vision defects and other irregularities in the transparency and shape of the tissues, in addition to the structures of the eye that may be affecting the visual system.

How Corneal Aberrometry Is Performed

Corneal aberrometry is a simple, non-invasive procedure that is performed in the ophthalmology office. The objective of this procedure is to analyze the possible imperfections that may exist in the cornea Of the eye.

A device called an aberrometer is used for this procedure. This device emits light beams that reflect off the cornea, the transparent front surface of the eye. The aberrometer collects information about how light bends as it passes through the cornea and creates a detailed map of corneal aberrations, that is, possible imperfections in its shape that can affect the patient's visual quality.

The whole process is very fast and is usually done in a few minutes.

Does ocular aberrometry require any preparation?

It is not necessary to carry out any special preparation before undergoing an ocular aberrometry since it is a very simple and non-invasive procedure.

It should be noted that, for those people who use contact lenses, it is advisable not to use them for a few hours before performing this test in order to obtain accurate results.

Whether you wear contact lenses or have an eye problem or have previously undergone eye surgery, from Área Oftalmológica We always advise notifying the specialist so that they are aware of it and take the measures that are deemed necessary. 

Frequently asked questions after having an ocular aberrometry

If you are considering undergoing an ocular aberrometry or have undergone one, you may have some related questions or concerns.

Below we answer those that, from our experience, are the most frequent:

Do I have to go fasting?

In the case of ocular aberrometry, it is not necessary to fast before the test. As we have already mentioned, it is a non-invasive and fast test that is not affected by food intake. Therefore it is not necessary to modify your eating habits before the appointment with your ophthalmologist.

How long does it take to get test results?

The results of ocular aberrometry are obtained almost immediately. Once the exam is complete, the specialist can analyze the data collected and explain the results obtained to you in a clear and simple way so that you can understand any type of imperfection that you may have and how it could affect your vision.

Can you drive after taking the test?

After undergoing an ocular aberrometry you can drive without any problem. The test itself does not affect your vision or dilate your pupils so you can resume your normal activities such as driving. 

Can I put on makeup after the ocular aberrometry?

After ocular aberrometry there are no restrictions on the use of makeup and therefore you can continue wearing your makeup as usual.

Can I wear contact lenses after the aberrometry exam?

Yes, once the ocular aberrometry is finished, you can use your contact lenses again without problem.

We take this opportunity here to remind you that it is recommended not to wear contact lenses a few hours before the exam in order to obtain more accurate results.

Do you need to perform an Aberrometry?

Whether you plan to have an aberrometry or it's been a long time since you've had a visual health exam, get in touch with our ophthalmologists at Área Oftalmológica Avanzada. We are happy to help you!
