<p>The Cataract is an eye condition wherein an individual has blurred vision. The eyesight is surrounded by bright spots and glares, and vision gets blurry due to which the person is not able to see clearly. <a href="../../cataract" target="_blank"><strong>Cataracts</strong></a> can be present in either of the eyes or both of them, depending upon the situation.</p>
<h2><span style="text-decoration: underline;"><strong>Causes of Cataracts:</strong></span></h2>
<p>Cataracts can happen due to any reasons that are listed below:</p>
<p>1. Older age<br />2. Diabetes<br />3. Congenital (children can be born with cataracts)<br />4. Smoking<br />5. Obesity<br />6. High Blood Pressure<br />7. Previous eye Injury or Surgery<br />8. Excessive Exposure to Sunlight<br />9. Taking Certain Medications<br />10. Excessive Drinking of Alcohol</p>
<h2><span style="text-decoration: underline;"><strong>Symptoms &amp; Signs of Cataract:</strong></span></h2>
<p>1. Blurry vision<br />2. Not able to see at night<br />3. Sensitivity to light<br />4. Need for a bright light while doing work<br />5. Probelm with glare of light<br />6. Seeing fading/ yellowish colours<br />7. Double vision in a single eye</p>
<p>If you are experiencing any of the above <a href="../../blog/signs-that-you-might-suffering-from-cataract" target="_blank">cataract symptoms</a>, it is best to contact your doctor. For cataract treatment, one must undergo <a href="../../cataract-surgery" target="_blank"><strong>cataract surgery</strong></a>. In this surgery, a cataract lens is inserted in the eye so that the patient is able to see clearly. <br /> <br />But before the surgery, there are certain cataract tests done by the eye doctors/ specialists to ensure the underlying condition.&nbsp;<a href="../../blog/7-ways-to-choose-the-best-eye-hospital-for-cataract-surgery" target="_blank">Best eye hospitals for cataract surgery</a> will ensure these tests before the operation. The eye tests are done to rule out the exact cause of the issue and know the severity of the cataract. In simpler terms, these tests help doctors to know about the underlying problems to create a personalized and precise cataract treatment plan.</p>

<h2><span style="text-decoration: underline;">Eye Tests Done to Check Cataract</span></h2>
<h3>1. This first set of tests (Ocular Examination) includes the following:</h3>
<p>a) The doctor evaluates the eye and checks for existing conditions that increase the risk of infections.</p>
<p>b) The doctor also checks for abnormalities in the cornea (the transparent part of the eye that allows light to enter).</p>
<p>c) They also check the tear films. If the tear film is dry, the doctor may take another approach.</p>

<h3>2. Magnification Test</h3>
<p>In this process, the doctor uses a special microscope known as the &lsquo;slit lamp&rsquo; to magnify the eye. This helps the eye specialist to diagnose the problem by examining the eye lens and knowing the severity of the cataract and helps in further cataract treatment.&nbsp;</p>
<h3>3. Biometry Test</h3>
<p>This is a very simple and integral test to measure the power of the <a href="../../types-of-cataract-lenses" target="_blank"><strong>artificial intraocular lens</strong></a>. There are three major kinds of lenses, i.e., monofocal lens, multifocal lens, and toric lens. These artificial lenses are then inserted into the eye once the cataract is removed.</p>
<p>In the biometry test, the length of the eyeball and the cornea is measured. These readings are different for every patient.</p>
<p>Based on these readings, the &lsquo;biometric machine&rsquo; calculates the powers of these artificial lenses.</p>
<h3>4. Corneal Topography</h3>
<p>This diagnostic procedure is done to check the curvature of the cornea in detail. This process can help in diagnosing if the cornea has bent outwards, causing blurred vision or misaligned squinted eyes. It is an important procedure that eye specialists/ doctors perform for cataract treatment.&nbsp;</p>
<h3>5. Blood Pressure Test</h3>
<p>Before the cataract surgery, it is essential to check the blood pressure of the patient. A patient having high BP is at risk of suffering bleeding at the back of the eye. This is called supra-choroidal haemorrhage and can be very dangerous. Once the BP is stabilized, the surgery takes place.</p>
<h3>6. Blood Sugar Test</h3>
<p>Blood sugar levels are also checked before a patient goes for surgery. If the patient is diabetic, the eye specialist is likely to delay the surgery to prevent any risk of postoperative infection. Once the blood sugar levels are below 200, the doctors undertake the surgery.</p>
<p><strong>Now there are different machines used to detect the cataract and undertake various eye tests. Here they are!</strong></p>
<h4>1. Endothelial Specular Microscopy (ESM)</h4>
<p>The ESM tests the severity of cataracts in detail. This machine looks for previous cornea surgery, trauma, or recurrent eye inflammations. It is a very valuable tool that lets the patient and the doctor be aware of the potential issues that might arise. This also helps the doctor in deciding the correct kind of surgery for the patient.</p>
<h4>2. Optical Coherence Tomography</h4>
<p>It helps in examining the anterior chamber, eye lens, and angles in the eye. This machine is used to take pictures of the retina and determine if there are any harmful changes. This is an important diagnostic tool that helps in choosing the right artificial intraocular lens for surgery.</p>
<h4>3. Optical Biometer</h4>
<p>This machine measures the length of the eye and allows the doctor to implant the right power of the lens in the patient&rsquo;s eye.</p>
<h4>4. Ultrasound Biometer</h4>
<p>This machine is used to know the accurate power of intraocular lenses (IOL) used for cataract surgery. It determines if the type of lens selected and the power is correct for the patient or not.</p>
<p>It is essential to get your Cataract treated as soon as possible because they can result in complete blindness as well. People who have high BP or diabetes need to take special care of themselves.<br /> <br />Cataracts can happen due to any reason. Thus, it is important to get the surgery done while you are in the initial phase. Cataract surgery will help you get a better vision in just four to six weeks. So, don't think much and give your eyes the gift of vision with cataract surgery!</p>
