Let’s start with a jaw-dropping statistic related to cataracts!
Did you know?
Nearly 25 million people over age 40 are affected by cataracts.
Sounds surprising, doesn’t it?
Cataract surgery refers to eye surgery when an eye doctor carefully removes the clouded lens from your eyes and replaces it with a clean artificial lens called IOL (Intraocular Lenses).
Many believe that cataracts are caused by age. But that’s not always the case. There could be multiple causes behind it such as diabetes, surgeries, overuse of steroids, and more.
But how can you know what type of cataract has affected you or your loved one?
Well, in this post, we’ll discuss the types of cataracts so you can recognize early signs and get an eye health check by an ophthalmologist.
What are the 3 Types of Cataracts?
Here are the 3 different types of cataracts.
#1. Nuclear Sclerosis
One of the most common types of cataracts is nuclear sclerotic cataract which occurs when the normal lens of your eye, positioned right behind the iris, becomes hardened and yellowed at its center, known as the nucleus. As already mentioned above, the disease is very common and tends to occur in people who are over 50 years old. In addition, this type of cataract typically takes years to develop before you begin to notice it. On the other hand, if you ignore it, it may cause blindness. If your eye doctor diagnosed you with this cataract type, try to get it correct at the earliest.
#2. Cortical Spokes
Another big form of cataract is a cortical cataract, which is a white opacity that starts in the outer part of the lens and gradually advances into the centre, which then creates a star-like pattern. These opacities tend to develop in the lens cortex, which is the outer layer of the lens situated around the central nucleus. However, if ignored, cataracts over time cause blurred vision; hence the patient finds it difficult to carry out his or her daily activities such as reading newspapers, watching TV, and so on.
#3. Posterior Subcapsular
Unlike other forms of cataracts, posterior subcapsular cataracts can rapidly advance and noticeable signs might appear in a matter of just a few months. This cataract begins as a small, cloudy, or opaque spot on the posterior part of the eye's lens. Additionally, this cataract is typically observed in diabetic patients or those who have been on long-term high doses of steroids.
Is Cataract Surgery Safe?
Cataract surgery is the most common and safest procedure in the U.S. The majority of those undergoing the procedure have no severe complications. However, it is still important to remember possible risks like retinal detachment and infection. Certain eye conditions or diseases that may lead to complications can increase the risk of an adverse event occurring during or after surgery. Thus, it would be essential to discuss your personal risk factors with your eye surgeon before surgery. Also, enquire about the steps they could take if any problems do arise during or after the procedure.
The Verdict
So, that’s all you need to know about different types of cataracts! Although different types of cataracts may impact vision in slightly different ways, all of them have the potential to cause appreciable vision loss, even complete blindness, if left untreated. Whatever the type, cataracts can be successfully treated and prevented from coming back through surgery. You should make an appointment with your eye doctor if you are aware that something is happening to your vision or it is not normal.
