Cataract formation is a natural part of the eye’s aging process. Cataract surgery is a common procedure; most people regain the vision they had earlier with the help of microsurgery. The procedure has a 98% success rate. There is very little discomfort or inconvenience and patients can usually return home few hours after surgery. We offer the best cataract surgery in Kolkata for adults & children. Here are some general information about what you can expect before, during and after your cataract surgery.

What is cataract?

A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. When the lens becomes opaque, light cannot pass through it and the vision becomes dim or blurred as the transparency of the lens is lost. A cataract is not a growth or a film over the eye.


The most common cause of cataract is the deterioration of the normal structure and degeneration of lens protein due to age within the lens of the eye with age. There may be other causes like diabetes, kidney disease, glaucoma, smoking, eye injuries, infection, and inflammation inside the eye which can be responsible for the cataract. Besides these reasons, cataract can also develop due to exposure to UV rays or prolonged use of certain medications.


Common Symptoms

Some of the most common symptoms are

  • blurry/clouded vision
  • sensitivity to bright light
  • dull appearance of colors
  • change in spectacle prescription
  • kid not reacting well to light or colorful objects (in case of pediatric cataract)

Kinds of lenses used in Cataract Surgeries

While Non-foldable lenses are made up of PMMA, a hard plastic material, Foldable lenses are either made of acrylic or silicone. The advantage of a foldable over a non-foldable lens is that the incision is very small and consequently the recovery period is much faster. Whichever the lens used, cataract surgery is a small procedure wherein the patient is discharged after a couple of hours and can safely go back home the same day.

  • Toric lenses
    For the past decade, ophthalmic surgeons have tried several methods to correct preexisting astigmatism during cataract surgery, including making incisions into the cornea to alter shape of the eye. Now due to the unique design of the Toric IOL, astigmatism can be reduced or corrected without further surgical intervention. 
  • Aspheric lenses
    The aspheric lens is designed to enhance contrast sensitivity, reduce dependency on glasses, and improve functional vision. 
  • Multifocal lenses
    Until recently the vast majority of patients who underwent surgery received a single-vision lens implant which required them to carry around reading glasses. However now Multifocal Accommodative IOLs are available which deliver accommodative-like vision across the entire visual spectrum. Post surgery, in certain patients, a very thin film develops behind the artificial lens. The treatment is a painless 10 minutes OPD procedure wherein the doctor cuts away this film through a process called Yag Laser.

Categories of Cataract Surgery

Cataract surgeries are microsurgeries and are broadly categorized into two:

  • Small Incision Cataract Surgeries (SICS): This involves removing the cloudy lens in one piece through a scleral tunnel of 6 to 7 mm on the eye. Through this incision, the artificial lens is also implanted. No suturing is required.
  • Phacoemulsification (Phaco): This is the latest advanced technique in cataract removal wherein a small ultrasonic probe is inserted into the eye through a cut of 3.2mm or less. This probe breaks (emulsifies) the cloudy lens into tiny pieces and gently sucks these out of the eye. The surgeon then implants the replacement lens through this cut.

When to see the doctor??? Planning for Surgery??

Cataract surgeries are micro surgeries and are broadly categorized into two:

  • You should not wait for the cataract to mature.
  • Consult your ophthalmologist as soon as you first experience blurriness in vision or colored rings in light.
  • In case of cataracts in new born child, take the child immediately to the ophthalmologist if it is uniocular white reflex of cataract is seen with the help of torch.
  • If binocular white reflex is seen with torchlight in children, you should also consult doctor.
