Cataract Surgery

What is a Cataract?

A cataract is when the eye’s lens becomes clouded, causing the light passing through the eye to become scattered and unfocused. The natural eye lens is made up of water and protein, so as the eye ages, some proteins can become discolored resulting in the blurring of vision.

What Causes Cataracts?

Various factors can give rise to cataracts in the natural lens of the eye. Factors that can cause cataracts include:


Cataracts develop as age advances. Cataracts typically begin forming around age 55, but can be seen in patients at earlier ages depending on physical health and predisposed risk factors.


Patients who have diabetes are at a higher risk of developing cataracts at an earlier age.

Excessive Exposure to Sunlight

Ultraviolet rays from direct sunlight can lead to the early development of cataracts. Sunglasses are an effective form of protection against direct sunlight.

Smoking/Drinking Alcohol

Smoking and excessive alcohol drinking are a predisposing factor for early cataract development


Obesity is a predisposing risk factor for diabetes and other systemic illnesses, which can in turn lead to early cataract development.

High Blood Pressure

Patients who have diabetes are at a higher risk of developing cataracts at an earlier age.

Excessive Exposure to Sunlight

Any form of direct blunt trauma can give rise to traumatic cataracts, even in young patients. Inflammatory eye diseases like uveitis can also add to the risk of cataracts.

Prolonged Use of Corticosteroid Medication

Any form of oral of topical steroid treatment for a long-term period of 6 months – 1 year can lead to cataracts.

Cataract Treatment Methods

Treatment of cataracts involves the removal of the natural lens and implantation of an intraocular lens in its place. Treatment methods include:


internal lens is emulsified with an ultrasonic device and removed from the eye.

Laser Cataract Surgery

affected lens is broken up and extracted using the CATALYS® precision laser, and replaced with an intraocular lens.

Phacoemulsification Benefits

  • safety and efficacy of cataract removal is less than catalys
  • less reliable and stable post operative refractive outcomes
  • capsulorhexis is variable and not centered, affecting iol positioning
  • excessive ultrasound power is needed for lens fragmentation
  • intraoperative complication rate is comparatively more

CATALYS- for Bladeless Cataract surgery

Dada Laser eye institute equipped with CATALYS

Laser Cataract Surgery Benefits

  • Increases safety & efficacy of cataract removal
  • Reliable & stable post operative refractive outcomes
  • Superior centration & circularity of capsulotomy & better iol positioning
  • Iaser pre–cuts the cataract into tiny segments making it easier to separate
  • Intraoperative complication rate is less compared to phaco surgery

Types of Intraocular Lenses:

Monofocal IOL : Restores vision for one area of focus – distance vision

Toric IOL : premium IOL that correct astigmatism as well as nearsightedness or farsightedness. Symfony toric IOL is the lens of choice.

Multifocal IOL : provide high quality vision at multiple distances i.e the multifocal lens of choice is symfony IOL which uses two advanced technologies that work together to:

  • elongate the focus of the eye to provide the extended range of vision
  • correct chromatic aberration (color distortion) to provide sharp vision
  • in all lighting conditions
