Cataract
Cataract (Hindi: Safed Motia or Motiabind) is age related changes in the natural lens of the eye leading to opacification and consequently causing blurring of vision. It starts after 5th decade of life and usually progresses with the age. The symptoms of cataract can vary according to the area of the lens involved and the blurring is early and more pronounced when central part is opacified as compared to the peripheral part of the lens. The other symptoms may be blurring of vision in bright light(Glare) , Coloured rings around the lights (Haloes), Multiple blurred images of an object (Polyopia), Blurring of vision in dim light, Difficulty in reading and driving, Repeated quick change in glasses power, eye strain and headache etc.Causes of cataract are injury (Traumatic cataract), Diabetes mellitus and various other diseases and thus can occur earlier also. In new born and infants it occurs due to genetic reasons or poor maternal health and diseases during pregnancy and then is called Congenital Cataract.
Now a days, Cataract operation is not disease curing procedure but has become more of a refractive procedure wherein clouded and opacified lens is removed and replaced by premium IOLs (Intraocular lens) implants which allows patients to see at all the distance (i.e. far, near, and intermediate) clearly. We are proud to say that we have successfully performed many surgeries followed by premium lens implantation giving smile on the faces of many satisfied patients.
Reason of Cataract Development
- Ageing: People older than 60 years of age are at the risk of getting cataracts.
- Exposure: Overexposure to UV rays can negatively affect the eyes and cause cataracts.
- Drug-induced: One can get cataracts 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
Symptoms of Cataract
- Hazy, fuzzy and blurred vision
- Double vision
- Increased sensitivity to light
- Poor night vision
- Frequent change in eyeglass prescription in the early stage
When Do I Know that I Need Cataract Surgery?

Which IOL to Choose?
Choice of IOL (Intra Ocular Lens) depends on your specific needs. If you do not mind wearing spectacles after cataract treatment, then a monofocal lens implant can be used. Usually, people use glasses only for reading purposes after the surgery.
If you do not want to wear spectacles after cataract surgery, then you can opt for presbyopia correcting IOLs.
By choosing for advanced presbyopia-correcting IOLs, you can improve your reading vision without compromising on distance vision. You can select presbyopia-correcting IOLs which includes accommodating IOLs and multifocal IOLs for a greater range of vision.
Monofocal Lens:
These were the most commonly used intraocular lenses up until multifocal lens were invented. Monofocal lenses have the ability to focus light rays for either distance or reading, hence after getting a monofocal lens implantation, a reading glasses are often required.
Multifocal lenses
They ensure good quality vision and eliminate the need for corrective glasses. They help patients see for most distances with minimal requirements of glasses. However, they are not suitable for night time driving as they might produce some amount of glares and halos. Therefore, suitability of these lenses can only be decided upon by your surgeon after a thorough examination.
Trifocal IOLs
Trifocal lenses offer clear vision at an intermediate level (generally an arm length). These lenses correct both near and far vision also. The most significant advantage of trifocal lenses is they allow the person to switch effortlessly between near, far, and intermediate distances.
EDOF IOLs:
It is a new technology that helps in the treatment of presbyopia. EDOF lenses create a single elongated focal point to enhance the depth of focus. It enhances the sharpness of vision at near, far and the in-between distances.
Toric IOLs:
These IOLs correct the pre-existing corneal astigmatism there by reducing the possibility of spectacle wear for distant vision post operatively.
ASPHERIC IOLs:
These IOLs gives good quality of vision post-operative due to the lens design, it also improves the contrast sensitivity of the patient and good night vision. These lenses also filter the harmful UV light and blue light which are said to be harmful to the retina.
ACCOMODATING IOLs:
These IOLs have flexible hinges that enables them to change focus for different distances hence providing clear distance, intermediate and near vision without glasses.
