Services • EYE CARE


A cataract is a common eye condition that occurs when the natural lens inside the eye becomes cloudy, leading to a progressive loss of vision. Cataracts often develop with age but can also be caused by factors like injury, certain medications, or underlying medical conditions.


As cataracts progress, they cause blurred vision, increased sensitivity to glare, and difficulty seeing in low light.


Treatment for cataracts involves surgical removal of the cloudy lens and replacing it with an artificial intraocular lens (IOL). Cataract surgery is a safe and effective procedure, allowing individuals to regain clear vision and improve their quality of life.

There are several types of intraocular lenses (IOLs) available for use in cataract surgery or lens exchange surgery. Some common types include:

  • Monofocal IOLs: These lenses provide clear vision at a single fixed focal point, usually set for distance vision. They may require the use of glasses for near or intermediate vision.
  • Multifocal IOLs: These lenses have multiple zones that allow for vision at different distances, such as near, intermediate, and distance. They aim to reduce the dependence on glasses for various activities.
  • Toric IOLs: These lenses are specifically designed to correct astigmatism, in addition to addressing cataracts or refractive errors. They can help provide sharper vision by reducing the need for glasses.
  • Accommodating IOLs: These lenses have the ability to change focus in response to the muscles of the eye, similar to the natural lens. They aim to provide a range of clear vision without the need for glasses.
  • Extended Depth of Focus (EDOF) IOLs:These lenses provide an extended range of clear vision, reducing the dependence on glasses for both near and intermediate distances.

The choice of IOL depends on factors such as the patient’s visual needs, lifestyle, and overall eye health. It is important to discuss the options with an Ophthalmologist to determine the most suitable type of IOL for an individual’s specific requirements.


Cataract Surgery Common Questions

Is cataract surgery worth it?

Cataract surgery is generally considered worth it for most patients because it effectively restores vision that has been impaired by cataracts. Cataracts cause the lens of the eye to become cloudy, leading to blurred vision, difficulty with glare, and other visual impairments. Surgery is often recommended when cataracts interfere with daily activities like reading, driving, or recognizing faces. The improvement in quality of life post-surgery is usually significant.

Is cataract surgery safe

Cataract surgery is one of the safest and most commonly performed surgeries worldwide. Like any surgery, it does carry some risks, such as infection, bleeding, or increased eye pressure. However, serious complications are rare. Advances in surgical techniques and technology have further improved the safety profile of cataract surgery.

What is the success rate of cataract surgery

The success rate of cataract surgery is very high. Most patients experience a significant improvement in vision. The exact success rate can vary depending on the definition of ‘success’ and the patient’s overall eye health. Generally, over 90% of surgeries are successful in improving visual acuity, with many patients achieving 20/20 or 20/40 vision post-surgery.

Can cataract surgery correct vision

Yes, cataract surgery can correct vision. The primary goal of the surgery is to remove the cloudy lens (the cataract) and replace it with an artificial lens, known as an intraocular lens (IOL). This not only clears the vision obscured by the cataract but can also correct refractive errors like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The type of IOL implanted can be selected to improve the patient’s overall vision, potentially reducing the need for glasses or contact lenses after surgery.

How long does a cataract eye surgery take

Cataract surgery is typically a quick procedure, often completed in about 15 to 30 minutes. It is usually done on an outpatient basis, meaning the patient can go home the same day. The duration can vary slightly depending on the specific techniques used and the complexity of the individual case.

Is cataract surgery painful

Cataract surgery is generally not painful. It is typically performed under local anesthesia, which numbs the eye area. Patients may feel some pressure during the procedure but should not feel pain. After the surgery, there might be some mild discomfort or irritation, but this is usually manageable with over-the-counter pain relief medication. Any severe pain after surgery should be reported to the ophthalmologist immediately, as it could indicate complications.

How long does it take for a cataract eye surgery to heal

The healing time after cataract surgery can vary among individuals, but generally, most people start to see improvements in their vision within a few days after the surgery. However, complete healing often takes about 4 to 6 weeks. During this time, it’s important for patients to follow their doctor’s instructions regarding eye drops and avoiding activities that could strain the eyes or expose them to potential contaminants. Regular follow-up appointments with the ophthalmologist are crucial to monitor the healing process and address any concerns.

Can you wear contact lenses after cataract surgery

Yes, it is possible to wear contact lenses after cataract surgery, but this largely depends on the individual’s specific needs and the type of intraocular lens (IOL) implanted. Some patients may not need contact lenses or glasses after surgery, especially if they receive multifocal or monovision IOLs. However, if residual refractive errors persist, contact lenses can be used. It’s important to wait until the eye has fully healed and to consult with an ophthalmologist before resuming the use of contact lenses.

Can you drive after cataract surgery

Patients are typically advised not to drive directly after cataract surgery. The ability to resume driving depends on several factors, including the clarity of vision achieved post-surgery, any post-operative side effects like glare or halos, and overall recovery. In many cases, patients may be able to drive within a few days to a week after the surgery, but this varies for each individual. It’s important to get clearance from the ophthalmologist before returning to driving.

Can cataract return after surgery

Once a cataract has been surgically removed and replaced with an artificial lens (IOL), the cataract itself cannot return, as the natural lens where cataracts form has been removed. 

Can you have cataract surgery more than once

In a typical scenario, cataract surgery is a one-time procedure per eye. Once the cataract is removed and replaced with an IOL, it generally does not need to be repeated. However, if there are complications or if the IOL needs to be replaced or repositioned for some reason, additional surgery might be necessary. This is extremely rare and would be assessed on a case-by-case basis by the ophthalmologist.
