What you need to know about medical tests before cataract surgery

Typically, a medical test is a must for every individual with a health issue. A medical examination is a method or way of diagnosing a patient. Without a medical test, no one can say the exact thing a patient is battling with. The body is one. There’s a connection within the body. And this has to do with one part of the body affecting the other. For instance, if you have an issue in your eye and you are ready for surgery, the doctor is carrying out an electrocardiogram on you. Remember, the electrocardiogram is a medical test used to check the health of one’s heart. You’ll be thinking about how an electrocardiogram correlates with the eye surgery you want to do.

So, if you have a cataract in your eye and you’re ready to undergo cataract surgery, don’t be scared when you see your doctor writing a series of tests that you need to do. Don’t think otherwise. There’s a tendency that one may quickly assume that the doctor is incompetent when one is about to do cataract surgery and he’s requesting a test that has to do with the heart. 

Therefore, this article aims at providing adequate information regarding medical tests before undergoing eye surgery. But before we jump to the details, it would be nice to kick start with the meaning of cataracts and what cataract surgery is all about.

What is a cataract? 

If you have seen some symptoms like the glare of light, trouble seeing at night, astigmatism, inability to read, etc., you need to consult your doctor for a proper checkup. You might be suffering from a cataract. Cataracts occur when there’s a solid or cloudy zone in the eye’s lens. This eye problem regularly begins when the protein in the eye generates clumps that prevent the lens from sending or transporting clear images to the retina. Don’t forget that the work of the retina is to change the light that comes via the lens into signals. Also, the retina leads signals to the optic nerve before the brain receives them. One fearful thing about cataract is that it occurs bit by bit and if one joke with it, it could result in total blindness. Click here to learn about treating cataracts.

What is cataract surgery?

Cataract surgery is eradicating the affected natural lens and replacing it with an artificial one. This surgery is done or carried out by a professional ophthalmologist. I can boldly tell you that everyone that has gone through this process can say something good about it. It is not as scary as it sounds to the ears. In some parts of the world, people get scared whenever they hear “surgery.” You don’t need any flattering words before you believe that the only way to restore one’s vision perfectly is by undergoing cataract surgery. It is the easiest and the safest method of getting one’s eye back to work. Don’t be deceived. People can tell you that all you need is eyeglasses. I am not saying eyeglasses cannot work. But I know that eyeglasses cannot perfectly correct your lens as undergoing this surgery would do.

Why medical test before cataract surgery

Although cataract eye surgery has a low risk of complications, some tests need to be carried out to ensure the stability of the heart to receive an operation on the body. If the heart is not in good condition due to fear, then the surgery must not be carried out. The heart must be ready to receive the operation and the touches before the surgery can be successfully done.

Also, carrying out some tests on you will help to know your health condition. For instance, it is good to have a test on the blood before cataract surgery. The medical examination helps to bring out the outcomes of other health conditions that may cause complications if cataract surgery is carried out. So, have it in mind that you will likely do some medical tests before undergoing cataract surgery. Once your doctor instructs you to do some tests, go ahead and do it. 

Why do people look less at the medical test before cataract surgery?

  1. The cost of the test: The cost of the medical examination is one of the reasons why some people love to skip that area. Some tests are expensive. One thing about these medical tests is that they are compulsory. For instance, the electrocardiogram that I mentioned earlier is costly. And it’s a must before one can undergo cataract surgery. The doctor must know the condition of your heart before conducting eye surgery. So, people like to skip this test because it is expensive.
  2. One test can lead to another: I said earlier that the body is one. After doing a medical examination, the result of one test might lead to another. I have heard about someone who did five different tests before undergoing cataract surgery. Therefore, people are always scared of doing the test because, in most cases, one test always leads to another.

Importance of medical tests before cataract surgery

No surgeon would take you through the procedure without carrying out some test to know your eye health condition. Medical trials are essential before one can do any surgery; it is also necessary before cataract surgery. I said earlier that the whole body must be ready for the process because all the body parts are one. So, the test result will show if the body is willing and prepared to go through the process. The condition of your heart is essential before undergoing cataract surgery. When a patient is scared on the day of the surgery, his blood pressure begins to rise. And once the blood pressure is high, the surgery cannot be successful. That is why you have to be in the clinic one hour before the surgery. Before the surgery, your surgeon must know your blood pressure, and how will he know your blood pressure without carrying out some test on you?
