Inside our eyes there is a natural lens. The function of this lens is to blend (refract) the light such that it helps us to see. This lens is clear so light rays can pass freely through it. When there is cataract, the lens becomes cloudy and it is like looking through a foggy or dusty car wind shield. Objects looks blurry, hazy and less colourful with Cataract.  


While ageing is the most common cause of Cataract due to the degeneration changes occurring in the natural lens leading to cloudiness, there might be other causes too.

  • Health disorders like Diabetes, Glaucoma, Inflammation inside the eye (Uveitis), Kidney disease, smoking, etc.
  • Prolonged and indiscriminate use of certain medications
  • Trauma and eye injuries, radiation treatment of upper body etc.


  • Blurring of vision
  • Seeing double images or multiple images
  • Glare and light sensitivity
  • Having trouble with vision at night
  • Seeing bright colours as faded
  • Difficulty in reading in dim light
If you notice any of these symptoms visit your ophthalmologist




When it becomes difficult to complete your regular activities because of a cataract, have a discussion with your ophthalmologist and plan your cataract surgery.


This is a minimally invasive procedure that typically does not require stitches and can be done using anesthetic drops only with no need for injections. A relatively painless procedure done using ultra-small incision (1.8 -2.00mm) to extract the cataract and followed by implantation of the latest ultra-thin foldable IOL’s, it is a less invasive procedure with shorter recovery time and negligible risks and complications.


IOL is a premium, tiny and artificial lens used to replace the natural lens of the eye after cataract surgery


– These lenses are made of biocompatible material and designed to remain in the eye permanently.These are ultra-thin foldable lenses which have a fixed focus for one distance. Hence after implantation of these lenses there is optimal distance correction, however reading glasses are required for near and immediate work.


– Multifocal IOL’s restore visual function and allow spectacle independence after their implantation with great levels of patient satisfaction. Their success depends on careful selection of patient added to a proper surgical technique.

Multifocal IOL’s can be


The principle is different Refractive power annular zones on the IOL. The part of lens (zone) you look through determines clarity of far, near or immediate distance. (Pseudoaccomodation).


These IOL’s have gradual diffractive steps in the IOL implant creating a smooth transition between focal points. These have less side effects such as glare and haloes. Though these IOL’s were designed to improve both near and distance vision. They might be associated with visual symptoms like haloes,glare and lower contrast sensitivity as they work by dividing light in different focuses as it enters the human eye. However, with time as the patient becomes comfortable, then perception of side effects decreases.


Bifocal lenses work on the principle of 2 focal points, hence the correction for intermediate vision is superior in trifocal IOL’s. Hence trifocal IOL’s provide a high patient satisfaction and excellent visual outcomes.

EDOF IOLS (Extended Depth of Focus)

– This is an option where due to retinal risks or active lifestyles. Multifocal IOLs are not an option. They provide optimized intermediate vision, though for near vision correction would be required. However, the vision quality is better than Multifocal IOLs with better contrast sensitivity and less photic phenomena.


– When the cylindrical correction required is > 1.0D Toric IOLs should be the IOL of choice. There are accessible in all formats.
