Cataracts and cataract removal

By Brandie Umar, Executive Director of ContentLast modified: March 25, 2011


Cataracts cause a clouding of the eye lens making vision blurred and if left untreated, cataracts can cause total loss of vision. Cataract surgery is a method of corrective eye surgery that removes the cataract and restores vision by replacing the damaged lens with an intraocular lens.


One in four people will develop cataracts after the age of 75. The risk of developing cataracts increases after 50 however people of all ages can develop cataracts and cataracts can be a congenital defect at birth.


Cataracts are formed when proteins in the lens of the eye begin to clump together. This causes the lens to cloud and your vision to become blurred.


Cataracts can occur in one or both eyes and many people require cataract extraction surgery in both eyes. 


Cataracts are a progressive condition.  If untreated cataracts will gradually cause more vision loss and can result in blindness.


The only treatment for cataracts is the removal of the cataract in a phacoemulsification cataract surgery procedure.


Contact a cataract surgeon to learn more about cataracts.

FAQ - Cataracts. Frequently asked questions about cataracts and cataract extraction surgery

Intracoluar Lens (IOL)

An IOL or Intraocular lens, replaces the eye's natural lens that is removed during cataract surgery.

There are two types of IOL that opthalmologists can use to replace the damaged lens - monofocal IOL or multifocal IOL.

Light Adjustable Lenses

Light Adjustable Lenses are an advance in ophthalmology treatment that could restore 20-20 vision to patients. 

Used primarily as a replacement lens after cataract surgery, light adjustable lenses can also be used to improve astigmatism and remove the need for glasses or contact lenses. For information about LALs and the choice of lenses after cataract surgery, contact an eye clinic here.
