Cataract Surgery in Delhi | Bharti Eye Foundation Guide

You Have Been Told You Need Cataract Surgery. Here Is Everything You Need to Know Before You Decide

A cataract diagnosis in Delhi follows a familiar pattern. A patient notices that colours seem duller than they used to, that reading requires more light than before, that headlights on the road at night have halos around them, that the spectacle prescription their optician gave them does not seem to help as much as it used to. They visit an eye doctor. The slit lamp confirms a cloudy lens. And the words that follow — “you will need surgery at some point” — produce a very specific kind of anxiety.

Surgery on the eye sounds frightening. Especially to patients who have never had any surgical procedure before, or whose parents or relatives had a very different cataract experience a generation ago, when the procedure required a week in hospital, bed rest with sandbags on either side of the head, and months of recovery with thick spectacles. That world no longer exists. Cataract surgery in 2026 is a fundamentally different procedure from what it was twenty years ago. But the fears have not caught up with the facts.

This article answers every question that patients at Bharti Eye Foundation, 1/3 East Patel Nagar, New Delhi ask before and after a cataract diagnosis. It is written by Dr. S. Bharti (DMC Reg. No. 6602), Founder and Medical Director of Bharti Eye Foundation, one of Delhi’s most established and trusted eye hospitals, with over 40 years of clinical practice in ophthalmology. Every medical fact in this article is sourced from published research, WHO data, the All India Ophthalmological Society (AIOS), or the National Programme for Control of Blindness and Visual Impairment (NPCBVI). Nothing is fabricated.

What Is a Cataract and Why Does It Form?

The natural lens of the eye sits behind the iris — the coloured part of your eye — and in front of the vitreous gel that fills the eye’s interior. In a young, healthy eye, this lens is perfectly transparent, flexible, and continuously adjusting its shape to focus on objects at different distances. Light passes through it cleanly and focuses precisely on the retina, producing a sharp image.

A cataract is simply a clouding of this natural lens. The word comes from the Latin cataracta — waterfall — because early observers thought the condition looked like water flowing across the eye. The clouding develops when the proteins that make up the lens gradually denature and clump together, changing the lens from transparent to progressively more opaque. Light scatters instead of focusing cleanly. Vision blurs, dims, and distorts.

What Causes a Cataract to Form

Age: The most common cause. After age 50, the lens proteins begin to degrade naturally. By age 60, a degree of lens clouding is present in the majority of the population, even if it is not yet symptomatic. According to the World Health Organization (WHO), cataracts account for 47.8 percent of all blindness worldwide and are the leading cause of avoidable blindness globally.
Diabetes: Elevated blood glucose causes osmotic changes in the lens that accelerate protein aggregation. Diabetic cataracts can appear significantly earlier than age-related cataracts and progress more rapidly.
Prolonged UV exposure: Ultraviolet radiation damages lens proteins cumulatively over decades. Delhi’s high UV index throughout the year makes sunglasses with UV protection genuinely important, not merely cosmetic.
Corticosteroid medications: Long-term use of steroid eye drops, oral steroids, or inhaled steroids is associated with posterior subcapsular cataract formation.
Eye trauma: A direct blow or penetrating injury to the eye can cause traumatic cataract formation, sometimes years after the original injury.
Congenital: Some cataracts are present at birth or develop in early childhood. These require urgent detection and treatment to prevent permanent amblyopia (lazy eye). Bharti Eye Foundation’s Paediatric Ophthalmology unit, led by Dr. Archana Gupta, manages congenital cataracts.

How Common Is Cataract in India

Cataract is the leading cause of blindness in India. According to the National Programme for Control of Blindness and Visual Impairment (NPCBVI), cataract accounts for approximately 66 percent of all blindness in India. Over 6 million cataract surgeries are performed in India every year — one of the largest cataract surgical programmes in the world. (Source: All India Ophthalmological Society, AIOS.) Despite this volume, a 2024 study published in the Indian Journal of Ophthalmology found that effective cataract surgical coverage in India was only 36.7 percent — meaning the majority of patients who need surgery have not yet received it.

How Do You Know If You Have a Cataract? The Eight Symptoms to Watch For

Cataracts develop slowly. Most patients do not notice the changes day to day because the brain compensates for gradually worsening vision. It is often a family member, or a routine eye examination, that first identifies the problem. These are the eight symptoms that most commonly bring cataract patients to Bharti Eye Foundation’s clinic in Patel Nagar:

1. Blurred or Hazy Vision That a New Spectacle Prescription Does Not Fix – This is the most common presentation. A patient gets a new spectacle prescription from an optician, finds it helps for a few weeks or months, and then vision deteriorates again. If a new prescription does not restore clear vision, the lens itself — not the refractive error — is the source of the problem. An ophthalmologist at Bharti Eye Foundation will identify this through a slit lamp examination within minutes of the consultation beginning.

2. Difficulty Reading in Normal Light – Early cataract causes a reduction in the amount of light reaching the retina. Reading — which requires high contrast between text and background — becomes difficult unless light is very bright. Patients describe needing to move to a window or increase the lamp intensity. This symptom often precedes the gross blurring that patients typically associate with cataract.

3. Halos and Glare Around Lights, Especially at Night – As the lens clouds, light scatters inside the eye rather than focusing cleanly. Street lights, car headlights, and tube lights appear surrounded by halos or starbursts. Night driving becomes progressively more hazardous. Glare from oncoming headlights may become disabling long before daytime vision is significantly affected. This is often the symptom that finally brings a patient to seek an ophthalmological opinion.

4. Fading or Yellowing of Colours – The cataractous lens gradually takes on a yellow-brown tint, filtering out blue wavelengths of light. Patients describe colours as less vivid, whites appearing yellowish, and the general quality of vision as “muddy” or “gloomy.” Because this change is so gradual, many patients are not aware of how much colour perception has deteriorated until after surgery restores it. The change in colour quality post-surgery is one of the most commonly reported pleasant surprises.

5. Double Vision in One Eye (Monocular Diplopia) – Some cataracts — particularly those affecting the nuclear centre of the lens — cause the lens to act as multiple lenses simultaneously. Light refracts through different parts of the lens at different angles, producing a ghost image or double vision within a single eye. This is distinct from binocular diplopia (double vision from misaligned eyes) and is confirmed by the fact that it persists even when the other eye is closed.

6. Frequent Changes in Spectacle Prescription – Nuclear sclerotic cataracts — the most common type, affecting the core of the lens — cause a phenomenon called “myopic shift.” The hardening and yellowing of the central lens temporarily increases its refractive power, effectively making patients who previously needed distance glasses suddenly able to read without them. This apparent improvement — sometimes called “second sight” — is actually a sign of advancing cataract. It is followed, inevitably, by progressive blurring of both distance and near vision.

7. The Vision Does Not Improve Even with the Best Glasses – This is the single clearest clinical indicator that a patient needs a cataract evaluation. When best corrected visual acuity — the sharpest vision achievable with any spectacle prescription — is no longer adequate for the patient’s daily activities, spectacles have reached their limit. The only remaining option to restore vision is surgical removal of the opaque lens.

8. Difficulty with Specific Tasks: Driving, Reading, Watching Television – The practical question — asked at every first consultation at Bharti Eye Foundation for a cataract patient — is: is your vision affecting your daily life? Difficulty driving, difficulty reading a newspaper or phone screen at normal arm’s length, difficulty recognising faces, or difficulty with any professional or personal task that requires clear vision is the threshold at which surgical intervention is appropriate for discussion.

When Is the Right Time for Cataract Surgery? The Answer Is Not “When It Is Fully Mature”

One of the most persistent and medically outdated misconceptions about cataract surgery in India is that the cataract must be “ripe” or “mature” before surgery can be done. This was true in the era when surgery required making a large incision and manually extracting the entire lens. It is emphatically not true in 2026.

Modern phacoemulsification — the standard technique at Bharti Eye Foundation — uses ultrasound energy to break the cataract into fragments that are suctioned out through a small incision of approximately 2.2 to 2.8 mm. Earlier-stage cataracts are softer and require less ultrasound energy to remove, making surgery faster, gentler, and associated with faster visual recovery. Waiting for a cataract to “ripen” or become mature actually makes surgery more complex, requires more ultrasound energy, and increases the risk of complications.

The appropriate time for cataract surgery is when the cataract is affecting the patient’s vision to the point where daily activities, safety, or quality of life are impaired. This is a clinical and personal decision made jointly by the patient and the ophthalmologist. It is not determined by how the cataract looks under the microscope, but by what the patient can no longer do because of it.

Cataract Surgery Techniques Available at Bharti Eye Foundation, Patel Nagar

All technology and procedures listed below are sourced from bhartieyefoundation.in and practo.com/delhi/hospital/bharti-eye-foundation-patel-nagar.

1. Phacoemulsification (Phaco) The international standard for cataract surgery since the 1990s and the procedure performed at Bharti Eye Foundation. A probe emitting ultrasound energy is inserted through a self-sealing incision of 2.2 to 2.8 mm. The ultrasound breaks the cataractous lens into tiny fragments, which are then suctioned out. An intraocular lens (IOL) is folded and inserted through the same small incision, unfolding within the lens capsule to take the permanent position of the original lens. No stitches are required. The incision self-seals.

2. Micro-Incision Phacoemulsification (MICS) An advanced form of phacoemulsification performed through an incision of 1.8 mm or smaller. The smaller incision results in even less surgically induced astigmatism and faster visual rehabilitation. At Bharti Eye Foundation, micro-incision phacoemulsification is performed as clinically appropriate.

3. Femto Laser Cataract Surgery The most technologically advanced cataract technique currently available. A femtosecond laser — the same class of laser used in Femto Bladeless LASIK — performs the corneal incision, the circular opening in the anterior capsule (capsulotomy), and pre-fragmentation of the lens nucleus with computer-guided precision. This reduces the ultrasound energy required during phacoemulsification, is particularly beneficial in complex cataracts, and delivers the most reproducible capsulotomy size and centration for premium IOL implantation. Femto Laser Cataract Surgery is available at Bharti Eye Foundation.

A significant historical note: Bharti Eye Foundation was the first institution in the Asia Pacific region to acquire the Sovereign Phaco Machine and the Zeiss IOL Master for precision cataract surgery. Dr. S. Bharti was also the first surgeon in Delhi to introduce eye drop anaesthesia for phacoemulsification in 1997, eliminating the need for injection anaesthesia and transforming patient comfort during cataract surgery in North India.

Intraocular Lenses (IOLs): What Replaces Your Natural Lens

The IOL is the permanent artificial lens implanted after the cataract is removed. Its selection is one of the most important decisions in cataract surgery, as it determines not only the level of post-surgical vision but also the degree of continued spectacle dependence.

Monofocal IOL: Provides clear vision at one fixed distance — usually distance. Patients will still require reading glasses for near work. The most widely used and most affordable lens type.
Toric IOL: A monofocal lens with additional cylindrical power correction, used in patients with significant pre-existing corneal astigmatism. Reduces or eliminates astigmatism and the need for distance glasses, but reading glasses are still required.
Multifocal IOL: Provides functional vision at both distance and near, reducing or eliminating the need for reading glasses. Not suitable for all patients; requires careful case selection and precise surgical technique.
Extended Depth of Focus (EDOF) IOL: Provides a continuous range of vision from distance to intermediate, with less dependence on reading glasses than monofocal lenses and fewer halos than multifocal lenses.

IOL selection at Bharti Eye Foundation is determined by Dr. S. Bharti’s clinical assessment of each patient’s eye dimensions (biometry using the Zeiss IOL Master, first acquired in Asia Pacific by Bharti Eye Foundation), corneal topography, lifestyle requirements, and realistic expectations.

Cataract Surgery at Bharti Eye Foundation: What Happens Before, During, and After

Before Surgery: The Pre-Operative Evaluation

Every cataract surgical candidate at Bharti Eye Foundation undergoes a comprehensive pre-operative evaluation that includes visual acuity testing, refraction, slit lamp examination, dilated fundus examination (to assess the retina behind the cataract), intraocular pressure measurement, corneal topography (to plan for toric IOL if needed), and optical biometry (IOL power calculation). Patients are asked to fast for six hours before surgery.

On the Day of Surgery: What Actually Happens

Cataract surgery at Bharti Eye Foundation is performed as a daycare procedure — you arrive in the morning and return home the same day. Eye drops are applied to dilate the pupil. Anaesthetic eye drops are then administered — the procedure is performed under topical anaesthesia at Bharti Eye Foundation, eliminating the need for an injection near the eye. The eye is held open with a speculum; you will not need to hold still or avoid blinking. The surgery itself takes between 10 and 20 minutes per eye. You will see light and movement during the procedure but will not feel pain. After surgery, you rest for 30 to 45 minutes in the recovery area. The operated eye is covered with a protective shield.

Recovery: What Patients Experience After Surgery

Most patients notice a significant improvement in vision within 24 to 48 hours of surgery.
The eye may feel slightly gritty or watery for the first few days. This is normal and settles.
Medicated eye drops are prescribed for four to six weeks after surgery: typically an antibiotic drop and an anti-inflammatory drop.
Avoid rubbing the eye for the first two weeks.
Avoid swimming, dusty environments, and heavy lifting for four weeks.
Final spectacle prescription is checked at six weeks post-surgery, once the eye has stabilised.
Driving is generally resumed within one to two weeks, subject to the post-operative review.
All follow-up visits are scheduled at Bharti Eye Foundation.

Is Cataract Surgery Safe? What the Evidence Shows

Cataract surgery is one of the safest and most commonly performed surgical procedures in medicine. A 2022 study published in JAMA Ophthalmology found that 98 percent of patients reported improved quality of life following cataract surgery, with reductions in falls and increased independence. According to data from the All India Ophthalmological Society (AIOS), the cataract surgery success rate in India ranges between 98 and 99 percent with modern techniques. The rate of serious post-operative complications has dropped to less than 1 percent nationally.

As with any surgical procedure, rare complications can occur — including infection (endophthalmitis), raised intraocular pressure, posterior capsule rupture, and posterior capsule opacification (PCO). An ophthalmologist at Bharti Eye Foundation will discuss all risks, benefits, and alternatives with you before any surgical consent is obtained.

Is Cataract Surgery Covered by CGHS, ECHS, and Health Insurance in Delhi?

This is one of the most frequently asked questions by patients at Bharti Eye Foundation’s Patel Nagar clinic, particularly from government employees, pensioners, and defence veterans. The answer is yes — cataract surgery is covered under multiple government and insurance schemes, and Bharti Eye Foundation is empanelled with all of them.

CGHS (Central Government Health Scheme)

Bharti Eye Foundation is empanelled with the Central Government Health Scheme (CGHS), which covers the medical expenses of Central Government employees, pensioners, and their dependents. Cataract surgery including phacoemulsification and IOL implantation is covered under CGHS. The specific rates and IOL types covered under the current CGHS schedule should be confirmed with Bharti Eye Foundation’s TPA desk at the time of consultation.

ECHS (Ex-Servicemen Contributory Health Scheme)

Bharti Eye Foundation is empanelled with ECHS, which covers defence pensioners and their dependants. Cataract surgery is covered under ECHS, subject to the specific empanelled rates applicable at the time.

CAPF (Central Armed Police Forces) — Ayushman CAPF

Bharti Eye Foundation is empanelled with Ayushman CAPF, covering all seven Central Armed Police Forces: Assam Rifles, CISF, BSF, CRPF, NSG, ITBP, and SSB. Personnel and their families are eligible for cataract surgery under this scheme.

Health Insurance (Private)

Bharti Eye Foundation accepts almost all major health insurance companies and their Third Party Administrators (TPAs) for cashless or reimbursable treatment. The Insurance Regulatory and Development Authority of India (IRDAI) mandates that health insurance policies cover cataract surgery when medically necessary, with minimum coverage of Rs 20,000 to 25,000 per eye. Patients with health insurance are advised to verify their specific policy’s terms, waiting periods, and network hospital status before booking.

Frequently Asked Questions: Cataract Surgery in Delhi

Q1. What is a cataract and how do I know if I have one?

A cataract is a clouding of the natural lens inside the eye, causing blurred or hazy vision, difficulty with night driving, halos around lights, and fading of colours. It develops gradually, often over years. Diagnosis is made by an ophthalmologist using a slit lamp examination. If your spectacle prescription is frequently changing and vision does not improve satisfactorily with new glasses, a cataract evaluation is recommended. Bharti Eye Foundation, 1/3 East Patel Nagar, New Delhi: +91-9211722214.

Q3. Is cataract surgery safe?

Yes. Cataract surgery is one of the safest surgical procedures in medicine. A 2022 study in JAMA Ophthalmology found that 98% of patients reported improved quality of life after cataract surgery. According to the All India Ophthalmological Society (AIOS), the success rate of cataract surgery in India ranges between 98 and 99 percent with modern phacoemulsification techniques. The rate of serious complications is below 1 percent nationally with experienced surgeons and appropriate facilities.

Q4. When is the right time to have cataract surgery?

The right time is when the cataract is affecting your vision to the degree that daily activities, safety, or quality of life are impaired. There is no need to wait for the cataract to become ‘ripe’ or ‘mature’ — this is an outdated concept. Modern phacoemulsification works better and more safely on cataracts that are not yet advanced. If reading, driving, recognising faces, or professional tasks are becoming difficult because of your vision, it is time to consult an ophthalmologist. Bharti Eye Foundation: +91-9211722214.

Q5. Is cataract surgery covered by CGHS in Delhi?

Yes. Bharti Eye Foundation, 1/3 East Patel Nagar, New Delhi is empanelled with CGHS (Central Government Health Scheme), DGEHS, ECHS, CAPF (all 7 forces), MCD, NDMC, and almost all private health insurance companies and TPAs.

Q6. What is phacoemulsification and how is it different from older cataract surgery?

Phacoemulsification (phaco) is the modern standard for cataract surgery. A small probe emitting ultrasound energy breaks the cataractous lens into tiny pieces, which are gently suctioned out through a self-sealing incision of 2.2 to 2.8 mm. No stitches are required. The procedure takes 10 to 20 minutes. Older cataract surgery required a large incision, weeks of bed rest, and thick post-operative spectacles. Phacoemulsification requires only eye drop anaesthesia — no injection — and most patients can resume normal activities within 24 to 48 hours. Dr. S. Bharti was the first surgeon in Delhi to introduce eye drop anaesthesia for phacoemulsification in 1997.

Q7. What is the difference between a monofocal and a multifocal lens (IOL)?

A monofocal IOL provides clear vision at one fixed distance — usually distance vision. Patients will still require reading glasses for near work. A multifocal IOL is designed to provide functional vision at both distance and near, reducing or eliminating reading glasses. Toric IOLs correct astigmatism in addition to distance power. EDOF (Extended Depth of Focus) IOLs provide a continuous range of vision from distance to intermediate. The appropriate IOL is chosen based on the patient’s eye measurements, lifestyle, and clinical assessment by Dr. S. Bharti at Bharti Eye Foundation.

Q8. What is femto laser cataract surgery and is it available at Bharti Eye Foundation?

Femto laser cataract surgery uses a femtosecond laser to perform the corneal incision, capsulotomy, and lens fragmentation with computer-guided precision before phacoemulsification. It reduces the ultrasound energy needed, produces a more precise capsulotomy, and is particularly beneficial for complex cataracts and premium IOL implantation. Yes, femto laser cataract surgery is available at Bharti Eye Foundation, 1/3 East Patel Nagar, New Delhi. Phone: +91-9211722214.

Q9. How soon will I see clearly after cataract surgery?

Most patients notice significant improvement in vision within 24 to 48 hours after cataract surgery. The eye continues to settle and stabilise over four to six weeks. Final spectacle prescription — if required — is checked at six weeks post-surgery. During this period, follow-up appointments are scheduled at Bharti Eye Foundation. The improvement in brightness, colour vibrancy, and clarity of vision is often dramatic and is one of the most consistently reported positive outcomes of cataract surgery.
