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 :-

People older than 60 years of age are at the risk of getting cataract.
An overexposure to UV rays can negatively affect the eyes and cause cataract.
One can get cataract due to prolonged usage of steroids and other prescription drugs.
People with diseases like diabetes are more likely to develop a cataract.
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.

Centre For Sight offers a number of surgical options depending upon the severity of the cataract, its cause and current condition of the patient’s eyes. The surgery best suited to the case is suggested after thorough testing only.


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:

  • Biometry/ Intraocular Lens (IOL) Work up: to check the IOL power required in the eyes.
  • Specular Microscopy: to check the status of the cornea and for any corneal disease.
  • OCT test: to check for any retinal pathology.
  • B Scan/ Ultrasound: to check the well-being of retina and other structures inside the eye.
  • Pentacam test: to test irregularities in cornea due to past LASIK/ PRK/ RK surgeries.

Surgeries for Cataract:

The breakdown of what happens in a cataract operation is that the surgeon removes damaged lens from the eye’s lens bag and replaces it with an artificial one that is clear and works in place of the original one.

There are many ways to perform cataract-removal surgeries, and here are the types of surgeries that we conduct at Centre For Sight:

  • Microincision Cataract Surgery (MICS): In this method, a 1.8mm to 2mm large incision is made by the surgeon for replacement of natural lens with an artificial lens. Everything from the incision to the breaking of the lens into smaller pieces for easing its removal, is done manually by the surgeon. It is an incredibly delicate task that requires a lot of skill from the doctors.
  • Femto Laser Assisted Cataract Surgery (FLACS): In this type of surgery, the first 5 steps of the surgery are automated, reducing the time and energy put into the otherwise manual surgery. The incisions are blade-free, the capsulotomy is precise and the cataract is considerably softer.

There a numerous types of intraocular lens (IOL) options that we use 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 Lens 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 that we provide at Centre for Sight:
    • Extended Depth of Focus Lens (Symfony 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 anaesthetic 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.

When you choose Centre for Sight, we provide you with only an expert team of surgeons, optometrists, radiologists, nurses and other staff to get the best results.

Transform how you see the world. With Robotic laser cataract surgery.

Cataract is the clouding of the lens of your eye with ageing that impairs vision. Now it’s easier than ever to regain clear vision after cataract. Take advantage of Robotic Femtosecond laser, the world’s first laser-automated technology for cataract surgery at Centre for Sight.

Why Choose Robotic Laser cataract surgery:

  • Blade Free cataract experience
  • Working of laser takes about 30-40 seconds only
  • Greater precision and safety
  • Critical steps of surgery are fully automated
  • Better visual outcome with quicker recovery


In cataract, there is a buildup of protein in the lens of the eye which makes it cloudy. This prevents light from passing clearly through the lens, thereby causing loss of vision.

Advancing age is a primary reason for cataract. With age, protein of the lens turns opaque. Other causes of cataract are metabolic disorders such as diabetes, excessive exposure to sunlight, lifestyle disorders like heavy alcohol consumption and smoking. Injury to the eye can also lead to clouding of the lens of the eye.

Treatment of Cataract

When cataract forms, surgery is the only way to treat it. In cataract surgery, the surgeon removes the clouded lens and puts an Intra Ocular Lens (IOL) in your eye. Your vision will be as good as pre-cataract days, though you may need to wear glasses. Over the years, cataract surgery has moved from vision restorative to refractive surgery, so that you have reduced need of glasses.

Best cataract treatment requires the combination of expertise of experienced doctors and latest technology working together. Centre for Sight is considered as one of the leading hospitals in India for cataract surgery. The hospitals are fully equipped with trained eye specialists for treatment of the patients.

Cataract does not spread from eye to eye but it often develops in both eyes together or after a brief gap.
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.
It happens in rarest of rare cases.
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 Centre for Sight after understanding the pros and cons of it.
Since laser operations like LASIK and PRK are done to improve vision without the need for glasses, it is important to inform your cataract team beforehand.
