Everything looks a little blurry lately. Lights have started to have halos around them at night. Reading has become harder, even with glasses. You keep thinking your specs need changing - but they already did, twice.
If this sounds familiar, it might not be your glasses at all. It might be a cataract.
The good news? Cataract surgery in Siliguri is one of the safest, most routine procedures in modern medicine. Most people come in, get it done, and go home the same day - seeing more clearly than they have in years.
Here's everything you need to know before your first consultation.
What Is a Cataract?
The lens inside your eye is naturally clear. It focuses light onto the retina so you can see sharp, bright, true-colour images. Over time - usually from age, but sometimes from other causes - this lens starts to cloud over. That clouding is a cataract.
It doesn't happen overnight. It creeps in slowly. First, things look a little hazy. Then colours seem duller. Then reading becomes a struggle. Night driving gets difficult because headlights create a glare that wasn't there before.
Cataracts are the leading cause of preventable blindness in India. And the only treatment is Cataract surgery - but surgery that works remarkably well.

Signs You Might Have a Cataract
Not everyone notices a cataract at first. Here's what to watch for:
- Blurry or cloudy vision that doesn't improve with new glasses
- Halos or glare around lights, especially at night
- Colours that look faded or yellowed compared to before
- Frequent prescription changes - needing new glasses every few months
- Double vision in one eye
- Difficulty reading even in good light
- Sensitivity to bright light or sunlight
Any of these, especially in someone over 50, is a good reason to get your eyes properly checked.
Types of Cataract Surgery Available in Siliguri
Not all cataract surgery is the same. At The Himalayan Eye Institute, we offer three approaches - chosen based on the individual patient's eye condition, lifestyle, and visual goals.
Micro-Phacoemulsification (Micro-Phaco)
This is the gold standard of modern cataract surgery - and the most commonly performed technique at our centre.
A tiny 2.2 mm incision is made in the eye. An ultrasonic probe breaks the cloudy lens into fragments, which are then gently removed. A foldable intraocular lens (IOL) - your new artificial lens - is rolled up and inserted through the same small opening, where it unfolds and settles into position.
No stitches. No large cuts. The wound is self-sealing. Recovery is fast.
Phacoemulsification (Phaco)
The standard phaco technique uses a slightly larger incision. It is equally effective and suitable for a wide range of cataract types and severities. Most routine cataract cases are handled through this approach.
Laser-Assisted Cataract Surgery
For patients who want the highest level of precision, laser-assisted surgery uses laser technology to make perfectly controlled incisions and pre-soften the lens - reducing the energy required inside the eye. It allows for a more accurate placement of the IOL and can reduce dependence on glasses for distance vision post-surgery.
Choosing the Right IOL - This Decision Matters
The lens that goes into your eye after the cataract is removed is called an intraocular lens (IOL). Choosing the right one for your life makes a real difference to how you see after surgery.
|
IOL Type |
Best For |
Glasses After Surgery |
|
Monofocal IOL |
Clear distance or near vision (one range) |
Usually still needed for reading or distance |
|
Multifocal IOL |
Both near and distance vision |
Significantly reduced dependence |
|
Toric IOL |
Patients with astigmatism |
Corrects astigmatism, reduces glasses need |
|
Extended Depth of Focus (EDOF) |
Natural range of vision, less glare than multifocal |
Minimal glasses needed |
Your surgeon will discuss which IOL makes the most sense based on your lifestyle - whether you drive a lot, work on screens, read frequently, or have other eye conditions alongside the cataract.
What Happens on the Day of Surgery
Most people are nervous before any surgery. Here's exactly what the day looks like - so there are no surprises.
Before surgery: You'll have dilating drops put in your eye. The surgical area is cleaned. Local anaesthetic drops are applied - no injections in most cases, and no general anaesthesia. You'll be awake throughout and comfortable.
During surgery: The procedure itself takes 10-30 minutes. You'll see light but not the surgical instruments. There is no pain. You may feel slight pressure at moments.
After surgery: A protective shield is placed over the eye. You'll rest briefly and then go home - the same day. Someone should drive you home or accompany you.
At home: You'll have eye drops to use for a few weeks. Don't rub the eye. Avoid dust and water getting into it for the first week. Most patients notice significantly better vision within 24-48 hours.
Is Cataract Surgery Safe?
Honestly - yes. Cataract surgery is one of the most commonly performed surgeries in the world, and it has one of the best safety records of any procedure in medicine. The vast majority of patients come out seeing significantly better, with no serious complications.
That said, no surgery is completely without risk. There can be temporary inflammation, and in rare cases, issues with the IOL settling into position. But these are uncommon - and when they do happen, they're manageable. The key is choosing a hospital with experienced surgeons, proper equipment, and a team that knows what they're doing.
What's worth knowing is that the longer a cataract is left, the harder the surgery becomes. A dense, mature cataract is a more complex operation than an early one. So ironically, waiting to feel "ready" for surgery can make the procedure itself riskier.
When Should You Have Cataract Surgery?
There's no fixed date on the calendar for this. No number on a chart that automatically means it's time.
The honest answer is - when the cataract starts running your life. When you're squinting at menus. When night driving has become genuinely uncomfortable. When you've changed your glasses twice in a year and it still hasn't fixed the blur. When you find yourself avoiding things you used to do without thinking.
That's the moment to have a proper conversation with your eye surgeon. Not to panic - just to understand where things stand and what your options are. For most people, once they've had that conversation, they wonder why they waited as long as they did.

Frequently Asked Questions About Cataract Surgery
Q1. What is cataract surgery and how does it work?
Think of the lens in your eye like a camera lens. When it fogs up - that's the cataract. Surgery removes that cloudy lens and puts in a clear artificial one called an IOL. The technique used most often is phacoemulsification - a small probe breaks the lens into tiny pieces using ultrasound, then gently clears them out. The whole thing is done through an incision smaller than 3mm. No stitches. It takes about 10-30 minutes.
Q2. Is cataract surgery painful?
Most patients say the thing they were most worried about turned out to be the least of it. Anaesthetic drops are applied before the procedure - your eye is completely numb. You'll be awake and you'll see light, but you won't feel anything being done. Some people notice a little pressure at certain moments. Pain, though? Almost never.
Q3. How long does recovery take after cataract surgery?
Most people wake up the next morning and already see better - sometimes dramatically so. Full vision stabilises over 4–6 weeks as the eye settles around the new lens. The first week is just about being careful - no rubbing, no swimming, keep dust out. Beyond that, normal life resumes pretty quickly.
Q4. Can both eyes be operated at the same time?
Not usually. The two eyes are done separately - typically 1–2 weeks apart. It might feel slower, but it's the safer way. The first eye heals, vision steadies, and then the second eye is done with a much clearer picture of how your vision is responding.
Q5. What happens if a cataract is left untreated?
It gets harder to treat - literally. A cataract that's left to mature becomes denser, cloudier, and significantly more difficult to remove. What's a routine procedure today becomes a more complex one a year or two from now. And eventually, the vision loss becomes severe enough to affect basic daily life. Earlier is always better with cataracts.
Q6. At what age does cataract surgery become necessary?
Age alone isn't the answer - plenty of people in their 50s need it, and some in their 70s are fine without it yet. The real question is: is the cataract affecting how you live? Driving, reading, recognising faces, working. When the answer starts being yes - that's when it's time to have the conversation with your surgeon.
Q7. Is the artificial lens permanent?
Yes. The IOL placed during cataract surgery is designed to last a lifetime. It requires no maintenance and cannot be felt. Once placed, it does not need to be replaced unless there is a specific complication.
