FAQ About Blurred Vision From Cataracts
Does your elderly loved one have a difficult time watching television and reading books due to blurred vision? Although astigmatism is a common eye condition, it is possible that your loved one is suffering from cataracts. The reason is that cataracts are common for elderly adults, but surgery can be performed in many cases to improve the clarity of vision. An ophthalmologist can examine your loved one's eyes to make a diagnosis, such as by looking for cloudiness in the lens of his or her eyes and performing several tests. Read more about cataracts below to learn important information before making an appointment for your loved one's eyes to be examined.
What Are the Causes & Symptoms of Cataracts?
Not only does growing old increase the risk for cataracts, but diabetes, steroids, and various other things can cause cataracts as well. When cataracts develop, it is due to the lens of one or both eyes becoming cloudy and affecting the ability of light to shine through as much as it needs to. A lack of light prevents the brain from being able to process images clearly, which is why images are blurry. Other than blurred vision, symptoms can include seeing a larger glare from lights than usual, double vision, and seeing shades of yellow. Your loved one will have the chance to discuss their symptoms during the eye examination appointment.
What Happens During Cataract Surgery?
Before cataract surgery is performed, your loved one's eye will be numbed using a local anesthetic. After your eye is numb, a special microscope will be used so the ophthalmologist can see the cataract. The cataract will then be broken up and removed from behind the retina. A new lens that is clear will be inserted, which is the last step in the surgical procedure. There is not a need for stitches to be used, as the small incision will heal on its own. You should expect your loved one to be in surgery for less than an hour, but the timeframe can vary.
Does Cataract Surgery Come with Risks?
Although cataract surgery is a safe procedure when performed by a professional, there are risks that you need to be aware of. For example, an eye infection is one of the risks, which is common with all types of surgical procedures. There is also the risk of eye pain, vision loss, and retinal detachment. An ophthalmologist will discuss all of the risks if it is determined that your loved one needs to undergo cataract surgery.
