Cataract Eye Surgery

One of the eyesight problems that people commonly suffer from is Cataract. In layman's language, a cataract is clouding of the natural lens in the eye. It becomes almost opaque over time and starts to affect vision. In a normal functioning eye, the light rays pass through a clear lens to form an image on the retina. The image signals sent to the brain form a person’s sense of sight. When the lens is not clear due to a cataract, no clear image can be formed on the retina resulting in poor vision.

Development of Cataract

The development of cataract happens slowly over the years in some cases, and rapidly in others. This can cause difficulties in performing daily activities like reading, driving or watching things from a distance.

Here are some of the main reasons for the development of cataract:-

  • Ageing: People older than 60 years of age are at the risk of getting cataract.

  • Exposure: An overexposure to UV rays can negatively affect the eyes and cause cataract.

  • Drug-induced: One can get cataract due to prolonged usage of steroids and other prescription drugs.

  • Diabetes: People with diseases like diabetes are more likely to develop a cataract.

  • Injury-induced: An injury to the eye can cause cataract or even complete loss of vision.


Cataract cannot be corrected with glasses, the clouding of the natural lens essentially prevents that. There is no specific medication to cure it, patients undergo surgeries for cataract removal instead.

Testing for Cataract :

At our centre, a team of medical professionals like optometrists, doctors, nurses and surgeons are assigned to the patient for testing and treatment. If the cataract is harmless, it can be left untouched. As soon as it starts to truly block vision in routine things, one should look into testing and surgical solutions.

The different types of tests we do here are:

  • Slit lamp examination and detailed dilated fundus examination with 90D lens

  • Biometry/ Intraocular Lens (IOL) Work up: to check the IOL power required in the eyes.

  • OCT test: to check for any retinal pathology.

  • Pentacam test: to test irregularities in cornea due to past LASIK/ PRK/ RK surgeries.

Surgeries for Cataract:

Aastha Eye Centre uses CENTURION SILVER Micro Surgical SYSTEM; the most advanced technology for Cataract Surgery (Approved by FDA). This cutting edge technology (Featuring OZil® Intelligent Phaco), combined with the expertise of Surgeons at AEC, delivers unmatched results, at par with the best in the world.

Microincision Cataract Surgery (MICS): 

The Phaco Cataract Surgeon makes an entry into the eye through an ultra-small Micro Surgical incision of CENTURION SILVER MICS Technology for Cataract removal. A high-frequency MICS Phaco tip is introduced through this MICS incision, breaking the hardest of hard Cataract into very small fragments. The fragments are then sucked out through the same tip in a computerized controlled manner. After removal of cataract, an Intra Ocular Lens (IOL) of the desired choice is implanted in the eye

For the best outcome, the centre uses Carl Ziess IOL Master for calculation of IOL (Lens) power.

The centre has highly skilled and experienced surgeons and trained manpower that together with state of the art technology and compassionate patient care makes it a unique and a safe experience for the patient.

The centre has given smiles to thousand of patients undergoing cataract surgery for nearly three decades. Over these years the centre has emerged as one of the best for Cataract surgery, fully equipped for handling complications.

There a numerous types of intraocular lens (IOL) options that are used to replace the original one:

There a numerous types of intraocular lens (IOL) options that are used to replace the original one:

  • Monofocal IOL: It is a lens beneficial for distance vision, but will require the patient to wear spectacles for computer work or reading after the surgery is performed.

  • Premium Monofocal IOL: This lens is not perfectly spherical in shape. Due to its high definition nature, it provides both quantity and great quality of vision with its contrast & light sensitivity, leading to great picture quality. Yet, the patient usually has to wear glasses after surgery because it’s still a monofocal lens.

  • Multifocal IOL: For most day-to-day activities, this lens provides great vision without the need for corrective glasses. Some patients still may experience halos and glares during night driving.

  • Newer Multifocal IOL: Most of the issues that were present in the multifocal lens are resolved in this lens. Thus, the halos and glares are also reduced. There are 2 main types of multifocal lens

    • Extended Depth of Focus Lens: Since this lens is binocularly implanted, it facilitates active near vision and good vision for distance, without any glares and halos.

    • Trifocal Lens: This lens is good for reading, distance vision and for intermediate distance vision including computer work.

As the anaesthesia wears off after surgery, patients might feel a dull pain in the eye. Initially, it might be red with wateriness and blurred vision. The operated area heals and the eye settles in 2 to 4 weeks after the surgery. The feeling of having some outside object inside their body slowly subsides after a few months. Contact the doctors again if any discomfort persists or arises.


  • Requires a small incision of 3.2 mm

  • Stitchless surgery

  • Cataract is emulsified and removed using an ultrasonic phacoemulsification probe

  • Foldable IOL is implanted

Aastha Eye Centre has always been adopting the latest technology in eye care that has resulted in improved visual outcome and comfort for the patient.

Aastha Eye Centre houses the most advanced phacoemulsification systems like the Centurion and offers a wide range of premium intraocular lens options to its patients.


What are the common symptoms of cataract?

Cataracts grow gradually with the slow blurring of vision that is not correctable by glasses. Some people get their vision quickly deteriorated, with difficulty in night time driving, glares, halos and overall foggy vision.

Can cataracts infect an eye because the other eye already has it?

Cataract does not spread from eye to eye but it often develops in both eyes together or after a brief gap.

Do cataracts develop due to getting old?

Cataracts very commonly occur in adult life. These are age-induced cataracts and may develop after 40 years of age. But not all people develop a cataract in old age and not all who develop it require treatment.

If I have a cataract in both eyes, can they be treated at the same time?

Cataract generally develops in one eye faster than the other, so it is advisable to operate the one in worse condition first. But it is possible to operate on both at the same time at AASTHA EYE CENTRE after understanding the pros and cons of it.

Does a previously done laser operation matter in cataract treatment?

No, But it is important to inform your doctor about any previous refractive surgery to avoid errors in calculating  IOL power.
