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.

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 “cataract 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.

Medical tests that are necessary before undergoing a cataract surgery

Some eye checkups by an experienced surgeon

If you want to know if your surgeon is an experienced one, he will do some checkups to see your eye condition. The eye doctor must measure the visual acuity before concluding whether a patient will be going for cataract surgery or not. The measurement of the visual acuity must be with updated eye power. Furthermore, he must examine your pupil, lids, and lashes and measure the intraocular pressure. Checkout some contract type on www.healthline.com/health

Not only that, but a professional eye doctor will also measure syringing of the lacrimal apparatus. However, the measurement of syringing of the lacrimal apparatus is optional. It can be done if there’s a need for it. Before an eye doctor confirms that the solution to your concern is to do cataract surgery, he must have examined the slit lamp. His checkup should include dilated examination of the cataract and fundus. 

Medical tests that are necessary before undergoing a cataract surgery

It is now left to your doctor to decide if the state of your eye health will need surgery or not. But all the above-detailed eye checkups must be done. 

Medical tests that an eye doctor must do before cataract surgery

  1. Biometry: This test is essential. It is a type of test used to measure the shape and size of the eye. No surgeon will conduct cataract surgery for anyone without doing a biometric test. A biometric test is used to calculate the power of IOL (Intraocular lens) implants required for cataract surgery. Have it in mind that you’re in the right place the moment they introduce a biometric test to you. Ultrasound (US) biometry (A-Scan) and half-done consistency interferometer (PCI)-based devices are the most-used methods for determining intraocular lens power. An “A” Scan is an ultrasound-based exact dimension of the eye length, which is mandatory to decide on the precise lens implant power before cataract eye surgery. Also, the intraocular lens master is the classiest and perfect way to know the power of the IOL implant for cataract surgery. The intraocular lens master allows for fast, perfect measurement of numerous eye areas.
  1. Corneal topography: This medical test is essential in particular situations like laser corneal surgery. This medical test must be carried out before cataract surgery to know the type and the power of the intraocular lens to be implanted. A competent surgeon must carry out this test on his patient before cataract surgery.

  1. Blood pressure test: A test to know the blood pressure will also be carried out. Before the surgery, the blood pressure must be in good condition. If the blood pressure is not in good condition, the cataract surgery should be postponed. If one’s blood pressure is high, one cannot undergo cataract surgery. Therefore, when your eye doctor tells you that you’ll need to do a test to know your blood pressure level, you should embrace it and do it. Have you ever wondered why the patient is allowed to sit and stay calm for one hour before the commencement of cataract surgery? Your ophthalmologist will ask you to sit for an hour to ensure that your blood pressure is normal. If your blood pressure is high, he must not take you through the process. It can lead to complications after the surgery. You might have heard about some complications like bleeding, infection, and after surgery. Therefore, complications may occur if one does not undergo the necessary medical test before cataract surgery
  1. OCT: OCT means optical coherence tomography. It is also essential. An eye doctor can measure the anterior chamber area of the lens with optical coherence tomography. Also, optical coherence tomography can be used to measure the angle of the lens as well. Then, with posterior segment optical coherence tomography, the doctor will know if there are changes in the macula. This is an essential tool to get a prognosis for the patient. Please note that if the optical coherence tomography is suggestive on any macular, then the choice of the lens may likely change.
