A cataract is the clouding of the eye&#8217;s natural lens, which can cause blurry vision, glare, reduced contrast, and difficulty seeing clearly. Cataracts are one of the most common causes of vision loss, especially among older adults. Symptoms of Cataract Blurred vision: Objects may look hazy or out of focus. Glare and light sensitivity: Bright sunlight, headlights, and indoor lighting may become uncomfortable. Reduced contrast: It may become harder to distinguish objects from their backgrounds. Poor night vision: Driving at night may become more difficult. Faded colors: Colors may appear dull, yellowish, or less vibrant. Frequent prescription changes: Glasses prescriptions may change more often than usual. These symptoms can also occur with other eye conditions, so a comprehensive eye examination is necessary to determine whether cataracts are responsible. What Causes Cataracts? Aging Age-related cataracts are the most common type.\u00a0Over time, proteins in the natural lens undergo structural and chemical changes. The lens gradually loses its transparency, resulting in cloudiness and reduced vision. Most age-related cataracts develop slowly over several years. Diabetes People with diabetes have a higher risk of developing cataracts, sometimes at a younger age. Elevated blood glucose levels can cause changes in the lens that affect its clarity. Poorly controlled diabetes may increase the risk of cataract development and progression. Ultraviolet (UV) Exposure Long-term exposure to ultraviolet radiation from sunlight may contribute to cataract development. Wearing sunglasses can help protect the eyes from UV exposure. Medications Long-term use of certain medications, particularly corticosteroids, can increase the risk of cataracts Eye Injuries and Previous Eye Surgery Trauma to the eye can damage the natural lens and cause a cataract. Depending on the injury, the cataract may develop immediately or years later. Certain eye surgeries and underlying eye conditions may also increase the risk. How are Cataracts Treated? Early Cataract Not every cataract requires immediate surgery. When a cataract is mild and does not significantly affect daily activities, the eye doctor may recommend monitoring its progression. Helpful measures include: Updating the glasses prescription when appropriate. Wearing sunglasses to reduce glare. Scheduling regular eye examinations to monitor vision and eye health. Cataract Surgery \u00a0Cataract surgery is currently the only established treatment for cataract removal. During surgery, the cloudy natural lens is removed and replaced with an artificial lens called an intraocular lens (IOL). Surgery improves vision by removing the cloudy lens and restoring a clear path for light to reach the retina. When is cataract surgery recommended? \u00a0An eye doctor may recommend surgery when cataracts begin to interfere with activities such as: Reading or using a computer. Driving, especially at night. Recognizing faces. Watching television. Working or performing daily tasks. Participating in hobbies and recreational activities. Surgery may also be recommended when cataract prevents the doctor from adequately examining or treating other eye conditions. There is no single visual acuity number that determines when everyone needs cataract surgery. The decision depends on the patient&#8217;s symptoms, daily visual needs, eye health, examination findings, and the potential benefits and risks of surgery. What Are the Different Types of Intraocular Lenses (IOLs)? Monofocal Lens A standard monofocal IOL is an artificial lens that provides one primary focal distance. In most cases, the lens is selected to provide clear distance vision. Patients can often see distant objects more clearly after cataract surgery but will generally need reading glasses for close-up activities. Toric Lens A toric IOL is designed to correct a significant amount of corneal astigmatism. Astigmatism occurs when the cornea or natural lens has an uneven curvature, causing light to focus unevenly. A toric IOL can reduce astigmatism and improve uncorrected vision after cataract surgery. Multifocal Lens A multifocal IOL is designed to provide vision at multiple distances by distributing light among different focal points. Depending on the lens design, it may provide distance and near vision, or distance, intermediate, and near vision. Extended Depth of Focus (EDOF) Lens An extended depth of focus (EDOF) IOL is designed to extend the range of clear vision from distance into intermediate distances. Rather than relying primarily on several distinct focal points like a traditional multifocal lens, many EDOF designs extend the range over which images remain in focus."}
