A cataract is a common eye condition where the normally clear lens of the eye becomes cloudy, leading to blurred vision, difficulty in seeing at night, and increased sensitivity to light. Cataracts develop gradually and are often associated with ageing, but they can also occur due to injury, medical conditions like diabetes, or prolonged exposure to UV light. If left untreated, cataracts can cause significant vision impairment and even lead to blindness.
Cataracts occur when proteins in the eye’s lens start to break down and clump together, forming a cloudy area that prevents light from passing through properly. This results in vision becoming less sharp and more hazy. While cataracts are common in older adults, they can also develop in younger people due to genetic factors, long-term use of certain medications, or previous eye surgeries. Fortunately, modern medical advancements have made cataract treatment highly effective, allowing patients to regain clear vision through safe and minimally invasive procedures.
Causes of Cataracts
Several factors contribute to the development of cataracts. Understanding these causes can help individuals take preventive measures to delay their onset.
Aging – The most common cause of cataracts is ageing. As people grow older, changes in the proteins of the eye’s lens cause it to become less transparent.
UV Radiation – Prolonged exposure to ultraviolet (UV) rays from the sun can accelerate the breakdown of proteins in the lens, increasing the risk of cataracts.
Diabetes – High blood sugar levels in diabetic individuals can lead to early cataract formation.
Eye Injuries – Trauma to the eye can damage the lens, leading to the development of cataracts.
Smoking and Alcohol Consumption – Excessive smoking and alcohol intake have been linked to a higher likelihood of developing cataracts.
Genetic Factors – Some people may inherit a predisposition to cataracts, making them more susceptible to the early onset of the condition.
Long-term Use of Steroid Medications – Prolonged use of corticosteroid drugs, especially in high doses, can contribute to cataract formation.
Symptoms of Cataracts
Cataracts typically develop slowly, and symptoms may not be noticeable in the early stages. However, as the cataract grows, the following symptoms may appear:
Blurred or cloudy vision that cannot be corrected with glasses
Difficulty seeing at night, often accompanied by halos around lights
Increased sensitivity to light and glare
Colours appearing faded or yellowish
Frequent changes in prescription glasses or contact lenses
Double vision in one eye
If these symptoms persist and begin to interfere with daily activities, it is important to consult an eye specialist for an evaluation. Early detection allows for better management and planning for treatment.
Types of Cataracts
Cataracts can be classified based on where they develop in the lens:
Nuclear Cataracts – These affect the centre of the lens and often cause a gradual yellowing or browning of vision.
Cortical Cataracts – These form around the edges of the lens and progress toward the centre, causing light sensitivity and glare.
Posterior Subcapsular Cataracts – These develop at the back of the lens and tend to cause blurred vision, particularly in bright light conditions.
Congenital Cataracts – Some infants are born with cataracts due to genetic factors, infections, or metabolic disorders during pregnancy.
Treatment for Cataracts
The only effective treatment for cataracts is surgery, as there are no medications or lifestyle changes that can completely reverse the condition once it has developed. However, in the early stages, vision problems can be managed with stronger glasses, anti-glare sunglasses, and proper lighting.
Cataract Surgery
Cataract surgery is a safe and highly successful procedure that involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL). The most common types of cataract surgery include:
Phacoemulsification – A minimally invasive technique where ultrasound waves are used to break up the cataract, which is then removed through a small incision. An artificial lens is inserted in its place.
Extracapsular Cataract Extraction – This method is used for advanced cataracts where a larger incision is needed to remove the clouded lens. It is less commonly performed today due to the effectiveness of phacoemulsification.
Laser-Assisted Cataract Surgery – Advanced laser technology is used to make precise incisions and soften the cataract before removal. This technique offers more precision and quicker recovery.
Cataract surgery is generally performed on an outpatient basis, meaning patients can go home the same day. Recovery time is usually quick, with most people regaining clear vision within a few days.
Preventing Cataracts
While cataracts cannot always be prevented, certain lifestyle changes can help reduce the risk of developing them:
Wear sunglasses with UV protection to shield the eyes from harmful sun exposure.
Eat a healthy diet rich in antioxidants, including green leafy vegetables, citrus fruits, and fish high in omega-3 fatty acids.
Quit smoking and limit alcohol consumption to reduce oxidative stress in the eyes.
Manage underlying health conditions like diabetes to prevent early cataract formation.
Have regular eye check-ups to detect cataracts at an early stage.
