Cataracts are a common condition that can cause vision impairment and significantly impact daily activities. This common eye condition develops when the lens of the eye becomes cloudy, blocking light from reaching the retina clearly. Understanding the nature of cataracts, their causes, symptoms, available treatment options, and consulting with a qualified cataracts specialist can help you make informed decisions about your eye health.
What Are Cataracts?
Cataracts occur when proteins in the eye’s natural lens begin to clump together, creating cloudy areas that interfere with vision. The lens, located behind the iris and pupil, normally remains clear to focus light onto the retina. When cataracts develop, this transparency diminishes, causing blurred or distorted vision.
The condition typically develops slowly, often beginning with small areas of cloudiness that gradually expand. Age-related cataracts are the most common type, though cataracts may also result from injury, certain medications, or underlying medical conditions. A cataracts specialist can determine the type and severity of cataracts through a comprehensive eye examination and diagnostic testing.
What Causes Them?
Age is the primary risk factor for cataract development, with most symptoms occurring in individuals over 60 years of age. The natural aging process causes proteins in the lens to break down and accumulate, leading to cloudiness over time. Medical conditions can accelerate cataract formation or cause cataracts to develop earlier than typical. Diabetes increases the risk, as elevated blood sugar levels can damage the lens proteins.
Certain medications, particularly long-term corticosteroid use, can increase cataract risk. Eye injuries, previous eye surgeries, and genetic factors may contribute to the development of cataracts. Smoking and excessive alcohol consumption have also been associated with higher rates of cataract development.
What Are the Symptoms?
The most common early symptom of cataracts is blurred or cloudy vision that cannot be corrected with glasses or contact lenses. This blurriness may initially affect only a small portion of the lens, making it barely noticeable. As cataracts progress, the cloudiness expands and vision becomes increasingly impaired.
Light sensitivity often accompanies cataract development, causing discomfort in bright environments or when driving at night. Colors may appear faded or yellowed, and some individuals experience double vision in one eye. Reading and close-up tasks become more challenging as cataracts advance. Frequent changes in eyeglass or contact lens prescriptions may also indicate the progression of cataracts.
What Are the Treatment Options?
Surgical removal represents the only definitive treatment for severe cataracts. Early-stage cataracts may be managed with updated prescriptions. When cataracts significantly interfere with daily activities or quality of life, surgery becomes the recommended treatment option.
Phacoemulsification is the most commonly performed technique for cataract surgery. This procedure involves making a small incision in the eye and using ultrasound energy to break up the cloudy lens into small pieces. The surgeon then removes these fragments and implants an artificial intraocular lens to restore clear vision.
Femtosecond laser-assisted cataract surgery offers enhanced precision in certain surgical steps. This advanced technique uses laser technology to create incisions and soften the cataract before removal. The laser may also correct astigmatism during the procedure, potentially reducing the need for glasses after surgery.
