What brings you here?
Could this be cataract?
When a clear lens becomes cloudy
A cataract develops when the eye’s natural lens loses clarity. The change is usually gradual and may affect daily life long before vision becomes severely reduced.
Sudden vision loss is not typical of an uncomplicated cataract. New flashes, a curtain or shadow, severe pain or sudden redness needs urgent eye assessment.
Blurred, hazy or dim vision
Glare or halos around lights
Difficulty with night driving
Colours appearing dull or yellowed
More light needed for reading
Frequent change in spectacle power
A dense cataract can markedly reduce clarity and contrast.
Cataracts vary in type and appearance—examination determines what is affecting vision.
An educational simulation
How cataract may change everyday vision
The effect differs from person to person. These simulations illustrate common descriptions and are not a diagnostic test.
The right time
A cataract does not have to become “ripe.”
The right time is when reduced vision interferes with something that matters to you—or when your examination shows a clinical reason not to wait.
Reading & screens
Are print, phones or computer work becoming tiring?
Driving & glare
Do headlights or low light reduce your confidence?
Daily independence
Is vision limiting mobility, work or familiar tasks?
Before the operation
Precision begins with evaluation
Not every patient needs every investigation. Testing is selected according to the individual eye, general health and proposed lens plan.
Vision
Refraction & cataract assessment
Confirms the type and severity of cataract and whether spectacles can still provide useful improvement.
Eye health
Pressure, optic nerve & retina
Identifies glaucoma, macular or retinal conditions that could influence planning or the final visual result.
Lens calculation
Lenstar optical biometry
Measures the eye accurately to calculate the power of the intraocular lens.
Cornea
Corneal topography
Pentacam assessment maps corneal shape, astigmatism and suitability for selected advanced lens strategies.
Personal priorities
How you use your vision
Reading, screens, driving, hobbies and willingness to use glasses all matter in lens selection.
Selected eyes
Additional targeted testing
OCT and other investigations may be advised when the retina, optic nerve or cornea needs closer assessment.
Corneal topography
Maps corneal shape and astigmatism for more informed lens planning.
Your cataract surgeon
Dr. Nidhi Gupta
Meticulous in planning. Equally attentive after surgery.
Dr. Nidhi Gupta is Medical Director of Delhi Eye Care and leads its Cataract, Refractive and Glaucoma services. With more than 18 years of ophthalmic experience and over 15,000 ophthalmic surgeries, she combines precise surgical planning with a calm, patient-centred approach.
She takes time to understand how each patient uses their vision, explains appropriate choices without pressure and remains closely involved throughout recovery.

Cataract surgery, simply explained
A small-incision, day-care procedure
The cloudy natural lens is removed and replaced with a clear artificial intraocular lens. Most modern cases are performed with phacoemulsification or micro-incision cataract surgery.
Delhi Eye Care uses the Alcon LEGION Vision System for controlled modern phacoemulsification and MICS.
1
The eye is numbed
Anaesthesia is selected for comfort and safety according to the patient and the eye.
2
The cloudy lens is removed
The cataract is gently broken and removed through a small incision.
3
A clear lens is placed
The selected intraocular lens is implanted inside the eye.
Alcon LEGION
Phaco platform for controlled ultrasound, irrigation and aspiration.
Lumera microscope
Illuminated magnification for precise microsurgical tissue handling.

Femtosecond laser-assisted cataract surgery can be arranged in selected cases when clinically appropriate or when a patient wishes to explore the option. It is not automatically superior for every eye.
The most personal decision
What do you want your vision to do?
Lens choice begins with your eye health and visual priorities—not with a package label.
Monofocal
A smooth optic designed primarily for one chosen focus.
Toric
Alignment marks help correct suitable corneal astigmatism.
EDOF
Optical design intended to extend the useful range of focus.
Multifocal / trifocal
Concentric optical zones distribute focus across distances.
Educational illustrations only; actual IOL designs vary by manufacturer and model.
| Lens strategy | Main aim | Glasses may still be needed | Important consideration |
|---|---|---|---|
| Monofocal | Clear focus at one chosen distance | Usually for other distances | Established option with strong optical quality |
| Enhanced monofocal | Distance with a useful extension toward intermediate | Often for near; sometimes intermediate | The useful range varies by lens and eye |
| Toric | Correct suitable corneal astigmatism | Depends on the underlying lens design | Requires accurate measurement and alignment |
| EDOF | Broader distance-to-intermediate range | Often for fine near work | Halos, glare or contrast trade-offs can occur |
| Multifocal / trifocal | Greater range, including near | Spectacle independence is not guaranteed | Not suitable for every cornea, retina, optic nerve or lifestyle |
The best lens is not necessarily the most expensive lens. It is the lens whose benefits and compromises fit your eyes, lifestyle and expectations.
One cataract. Many different eyes.
Why specialist planning matters
Cataract surgery may need additional planning when other eye conditions are present. Delhi Eye Care can coordinate cataract care with its retina, glaucoma, cornea and refractive services.
Diabetes or retinal disease
Glaucoma
High myopia
Corneal astigmatism or irregularity
Previous LASIK or refractive surgery
Dense or complex cataract
Ethical guidance
A recommendation, not a sales pitch.
You will be shown the options suitable for your eye. Their benefits, limitations and costs will be explained transparently—without pressure to choose the most expensive lens or technology.
The DEC cataract journey
Care that continues beyond surgery
BEFORE
Plan carefully
Measurements, medical review, medication instructions, eye-health assessment and an unhurried lens discussion.
SURGERY DAY
Keep it clear
Day-care admission, appropriate anaesthesia, careful surgery and written discharge guidance.
AFTER
Recover with support
Prescribed drops, eye protection, activity advice, planned follow-ups and help if recovery is not progressing as expected.
Seek prompt advice after surgery for increasing pain, rapidly worsening vision, marked redness, discharge, new flashes or floaters, or a curtain/shadow.

Common questions
Before you decide
How do I know when my cataract is ready for surgery?
Surgery is usually considered when cataract-related vision affects activities important to you, or when your ophthalmologist finds a clinical reason not to wait. A cataract does not ordinarily need to become “ripe.”
Is cataract surgery painful?
The eye is numbed before surgery. Most patients experience little or no pain during the procedure, although sensations of pressure, touch or bright light can occur. Mild irritation during early recovery is possible.
Which cataract lens is best for me?
There is no single best lens for everyone. The choice depends on corneal measurements, retina and optic-nerve health, astigmatism, previous eye surgery, night-driving needs, reading habits and expectations about spectacles.
Will I be completely free from glasses?
No lens can guarantee complete spectacle independence. Some options can reduce dependence on glasses at selected distances, but each has limitations that should be discussed before surgery.
Can a cataract return after surgery?
The removed cataract cannot return. Months or years later, the thin capsule behind the lens can sometimes become cloudy. This is called posterior capsule opacification and can usually be treated with a brief YAG laser procedure.
What if I have diabetes, glaucoma or retinal disease?
Surgery may still be appropriate, but the condition can change the timing, investigations, lens choice, treatment plan or likely visual result. Coordinated specialist planning is particularly important.
How long does recovery take?
Many patients notice improvement within the first few days, but vision may fluctuate while the eye heals. The individual timetable depends on the cataract, the eye, the surgery and any other eye conditions.
What determines cataract surgery cost?
Cost varies with the clinical complexity, surgical setting, investigations, chosen intraocular lens and insurance or scheme coverage. Delhi Eye Care explains suitable options and costs transparently before surgery.
