Cataract is a medical condition affecting our eyes. It occurs when protein accumulates and hardens on the lens of the eye. People who have cataracts experience blurry vision, difficulty seeing at night, sensitivity to light, double vision, and falling. Untreated cataracts may lead to blindness.
There are actually different types of cataracts. Once a person is diagnosed with one of these, he or she needs to have cataract surgery.
Nuclear Sclerotic Cataract
Nuclear sclerotic cataracts are the most common, occurring among people above the age of 60. They form in the central area of the lens and are yellow or brown in color. People suffering from nuclear sclerotic cataract will first experience losing focus. These cataracts take time to develop and needs surgery when it comes too severe.
Posterior Subcapsular Cataract
Posterior subcapsular cataracts form in the back area of the lens. It occurs among people suffering from diabetes, nearsightedness, or retinitis pigmentosa. It also affects people who use steroids in high doses. This is the fastest-forming cataract among all types, exhibiting symptoms in a few months. This kind of cataract affects reading and causes light glares and halos to appear around objects. People who receive a posterior subcapsular cataract diagnosis need to prepare for surgery soonest.
Cortical cataracts are white formations that develop around the lens cortex of the eyes. They occur due to changes in the water content of the lens fiber. It causes vision to blur, as well as depth perception problems. People who have diabetes can also suffer from cortical cataracts.
Secondary cataracts occur due to other diseases, medications, and unhealthy lifestyle. This usually happens to people with diabetes. People with arthritis, high cholesterol levels, hypertension, hypoparathyroidism, nutritional deficiencies, obesity, and other eye diseases such as glaucoma may also develop cataracts. Children who have Lowe’s Syndrome also have cataracts.
Medications such as cortical steroid treatments and benzodiazepines, as well as exposure to tranquilizers causes cataracts. Excessive smoking, alcohol intake, and sun exposure also leads to the development of cataracts.
Secondary cataracts also appear many years after a person’s cataract surgery. It affects only a very small population of patients. You can treat this kind of secondary cataract with a follow-up surgery that is called YAG laser capsulotomy.
Congenital cataracts may form in infants with low birth weight or infections. Pregnant women who have German measles are prone to have children with congenital cataracts.
