Signs You Need Cataract Surgery — When to See a Doctor

The most common signs you need cataract surgery include blurry or cloudy vision, difficulty seeing at night, increased sensitivity to glare, fading colours, and needing frequent changes in your glasses prescription. If these symptoms interfere with daily activities, it is time to consult an ophthalmologist.

Have you noticed that your vision is not as clear as it used to be? Do lights seem to have a halo around them, or do colours look washed out? You might be developing cataracts, known as motiyabind in Hindi. Cataracts are extremely common, especially after the age of 50, and the good news is that modern surgery can restore your vision quickly and safely. Here is how to recognise the signs and know when it is time to see a doctor.

What Are Cataracts (Motiyabind)?

A cataract is a clouding of the natural lens inside your eye. Think of it like a clean glass window slowly becoming frosted over time. The lens, which sits behind your pupil, is normally transparent and helps focus light onto the retina at the back of your eye. When proteins in the lens break down and clump together, they form a cloudy area that blocks or distorts light. This clouding is a cataract.

Cataracts develop gradually. In the early stages, you may not notice any change at all. But as the cataract grows, your vision becomes progressively more blurred, dim, or discoloured. Without treatment, cataracts can eventually lead to severe vision loss or blindness.

Common Symptoms of Cataracts

Cataracts can affect one or both eyes. Watch for these warning signs:

Risk Factors: Who Gets Cataracts?

While cataracts can happen to anyone, certain factors increase your risk:

• Age: The most significant risk factor. Most cataracts develop in people over 50, and the majority of people over 70 have some degree of cataract formation.
• Diabetes: People with diabetes are significantly more likely to develop cataracts at a younger age. High blood sugar levels accelerate lens clouding.
• Prolonged sun exposure: Years of exposure to ultraviolet (UV) light without eye protection increases risk. This is particularly relevant for farmers and outdoor workers.
• Eye injury or surgery: Previous trauma to the eye or past eye surgery can lead to cataract development.
• Family history: If your parents or siblings had cataracts early, you may be at higher risk.
• Smoking and alcohol: Both are linked to earlier and faster cataract development.
• Prolonged steroid use: Long-term use of corticosteroid medications can cause cataracts.

When Should You See a Doctor?

You should visit an eye doctor if any of these symptoms begin to affect your daily life:

• You struggle to read, cook, sew, or do close-up work that was previously easy
• You feel unsafe driving, especially at night
• You frequently need to change your spectacle prescription
• You find yourself needing brighter light for everyday activities
• Your vision makes it difficult to recognise faces or watch television

Do not wait until your vision is severely affected. Early detection gives you more options and allows you to plan your treatment. A simple eye check-up can tell you exactly where you stand.

How Are Cataracts Diagnosed?

Diagnosing cataracts is straightforward and painless. During a comprehensive eye examination, your doctor will perform:

• Visual acuity test: Reading letters on an eye chart to measure how sharp your vision is at various distances
• Slit-lamp examination: A specialised microscope with a bright light that allows the doctor to examine the structures of your eye in detail, including the lens
• Dilated eye examination: Eye drops are used to widen your pupil, giving the doctor a clear view of the lens and retina to assess the extent of the cataract
• Tonometry: Measuring the pressure inside your eye to rule out glaucoma

When Is Surgery Needed?

In the early stages of cataracts, your doctor may recommend updated spectacles, better lighting, or magnifying lenses to manage your symptoms. However, surgery becomes necessary when:

• Glasses can no longer correct your vision to a satisfactory level
• The cataract significantly interferes with your daily activities and independence
• The cataract prevents treatment of another eye condition, such as diabetic retinopathy

The decision to have surgery is ultimately yours, made in consultation with your ophthalmologist based on how much the cataract affects your quality of life.

Modern Surgery Is Quick and Safe

If the idea of eye surgery makes you nervous, it helps to know that cataract surgery is one of the most commonly performed and safest surgeries in the world. Here is what you can expect:

• The procedure takes just 15 to 20 minutes
• It is performed under local anaesthesia, so you feel no pain
• The cloudy natural lens is removed and replaced with a clear artificial intraocular lens (IOL)
• No stitches are needed in most cases
• You go home the same day
• Vision improvement begins within 24 to 48 hours
• Most patients can return to normal activities within a week

Do Not Wait Too Long

Many patients, especially in rural areas, delay treatment hoping their vision will improve on its own. Unfortunately, cataracts never resolve without surgery, and they only get worse over time. An advanced or "mature" cataract becomes harder and denser, making surgery more complex and increasing the risk of complications. Early cataract surgery is simpler, safer, and produces better visual outcomes.

If someone in your family is struggling with their vision, encourage them to get a simple eye check-up. Restoring their sight could take as little as 20 minutes.
