Cataract surgery is a medical procedure used to treat cataracts, where the eye’s natural lens becomes cloudy, leading to impaired vision. The surgery involves removing and replacing the cloudy lens with an artificial intraocular lens (IOL) to restore clear vision. Cataracts commonly develop with age but can also occur due to injury, certain medical conditions, or prolonged exposure to UV radiation.
Cataract procedure is one of the most frequently performed and successful surgeries worldwide. Technological advancements have made it a relatively quick, minimally invasive procedure, often completed in under 30 minutes. Most patients experience a significant improvement in their vision within a few days of surgery, allowing them to quickly return to their daily activities.
Phacoemulsification, or “phaco,” is the most common type of cataract operation. During this procedure, a small incision is made in the eye, and an ultrasonic device is used to break up the cloudy lens into tiny fragments, which are then suctioned out. An artificial intraocular lens (IOL) is then implanted. Phacoemulsification is minimally invasive and requires a short recovery period.
In cases where the cataract is too dense for phacoemulsification, an extracapsular cataract procedure may be performed. There’s a larger incision made to remove the cloudy lens in one piece. Once the lens is removed, an IOL is implanted. Although recovery time is slightly longer than phacoemulsification, it is still an effective cataract treatment.
This technique uses laser technology for cataract removal. The femtosecond laser makes precise, bladeless incisions in the eye, which helps reduce the risk of complications. The laser is also used to break up the cataract for easier removal. This method is often combined with phacoemulsification for better outcomes.
Cataract surgery is generally recommended when cataracts significantly impair your vision and daily life. Early-stage cataracts may not require immediate surgery and can often be managed with stronger eyeglasses or better lighting. However, surgery becomes the most effective treatment option once the cataract progresses and starts affecting your ability to perform everyday activities—such as reading, driving, or recognising faces.
It’s essential to consult with an eye doctor to assess the severity of your cataracts and determine whether surgery is the right choice. While there’s no rush to treat cataracts in the early stages, delaying surgery for too long can lead to more complications.
Before the Surgery: Before cataract surgery, your eye doctor will thoroughly examine your eyes to determine the appropriate type and power of the intraocular lens (IOL). You may also be advised to stop wearing contact lenses and use prescribed eye drops before surgery to reduce the risk of infection. On the day of the surgery, you will be asked to refrain from eating or drinking for a few hours prior to the procedure. You’ll also be informed about the cost of a cataract operation.
During the Surgery: Cataract eye surgery is performed under local anesthesia, and you will be awake but feel no pain during the procedure. A small incision is made in the cornea, and the cloudy lens is carefully removed using a method such as phacoemulsification or extracapsular extraction. The surgeon will then insert the IOL to replace the removed lens. The incision is so small that stitches are usually not required, and it heals naturally.
After the Surgery: Following the surgery, you will be given protective eyewear and advised to avoid rubbing your eye. You may experience mild discomfort, itching, or blurred vision in the first few days after the surgery. Eye drops will be prescribed to prevent infection and aid healing. Most patients can resume normal activities within a few days, but it is essential to avoid heavy lifting, bending, or swimming until your eye has fully healed.
After cataract removal, an Intraocular Lens (IOL) is implanted to restore clear vision. An IOL eye lens replaces the clouded natural lens with an artificial one, improving sight at various distances. The choice of IOL for cataract surgery plays a crucial role in determining vision clarity for near, intermediate, and far distances.
1. Monofocal Lens (IOL)
Function & Suitability: Provides clear vision at a single distance (far, intermediate, or near) and is ideal for those comfortable using glasses for other tasks.
Vision Benefits: Excellent far vision but requires glasses for near and intermediate vision.
2. Multifocal Lens (IOL)
Function & Suitability: Offers multiple focal points for near, intermediate, and far vision, making it perfect for those who want to reduce dependence on glasses.
Vision Benefits: Clear vision at all distances, though some may experience mild halos at night.
3. Extended Depth of Focus Lens (EDOF) IOLs
Function & Suitability: Provides a continuous range of vision for those needing sharp far and intermediate vision with minimal glare.
Vision Benefits: Excellent far and intermediate vision; near vision may require reading glasses.
4. Toric Lens (For Astigmatism Correction)
Function & Suitability: Specifically designed for astigmatism correction, these lenses provide sharper vision at a chosen distance, making them ideal for patients with astigmatism.
Vision Benefits: Clear far vision; intermediate and near vision may require glasses.
The best types of IOL for you depend on your lifestyle, visual needs, and overall eye health. At Centre For Sight, we provide expert consultation to help you choose the most suitable cataract IOL lens—whether it’s a monofocal lens, multifocal lens, toric lens, or other advanced options—for maximum clarity and comfort.

The cost of cataract surgery varies based on the type of lens used, the surgeon’s expertise, and the clinic’s location. This includes the cost of the intraocular lens, pre-operative evaluations, and post-operative care. In some cases, insurance may cover the surgery, especially if it is deemed medically necessary to improve vision. Centre For Sight, also offers flexible EMI options to make the procedure more affordable.

Yes, LASIK provides permanent correction for refractive errors. However, natural aging processes, such as presbyopia or cataracts, may affect vision later in life.
The LASIK surgery cost in India varies depending on the type of procedure, technology, and location but typically starts from 20,000 per eye.
LASIK stands for Laser-Assisted In Situ Keratomileusis, a procedure that reshapes the cornea to correct vision.
Many patients achieve 20/20 vision after LASIK, but outcomes depend on individual eye conditions and kind of refractive errors.
The ideal age for LASIK is between 18 and 40 years, when vision is stable, and there are no age-related conditions like presbyopia or cataracts.
No, LASIK is not painful. Numbing eye drops are used during the procedure, and most patients experience only mild discomfort during recovery.
While LASIK is highly effective, its success rate varies. Over 95% of patients achieve 20/20 vision, depending on their initial refractive error.
Temporary side effects like dry eyes, halos, and glare may occur but typically resolve within a few weeks. Serious complications are rare.
