Cataract is a clouding of the eye’s natural lens. Cataract is the most common cause of vision loss in people over the age of 40 and is the principal cause of blindness in the world.
Symptoms and signs
- Cataract starts out small and at first has little effect on your vision.
- You may notice that your vision is mildly blurred, like looking through a cloudy piece of glass.
- Cataract may make light from the sun or a lamp seems too bright or glaring.
- Colours may not appear as bright as they once did.
Choosing your Intraocular Lens (IOL) before surgery
Intraocular lenses (IOLs) are medical devices that are implanted inside the eye to replace the eye’s natural lens when it is removed during cataract surgery. Today there is a wide variety of premium IOLs to choose from. The suitable intraocular lens for you depends on many factors, including your lifestyle and your specific visual needs.
Monofocal IOLs are set to provide good vision correction for far distances. Most people who choose monofocals have their IOLs set for distance vision and use reading glasses for near activities.
Multifocal IOLs are another category of presbyopia-correcting IOLs that can decrease your need for reading glasses or computer glasses after cataract surgery. These premium IOLs contain added magnification in different parts of the lens to expand your range of vision so you can see objects clearly at all distances without glasses or contact lenses.
Trifocal implant gives patients a better chance to enjoy clear vision at all distances with maintained contrast sensitivity and lower visual disturbance.
TORIC IOL (FOR ASTIGMATISM)
Toric IOLs can correct astigmatism because they have different powers in different meridians of the lens. Toric correction is available for both monofocal and multifocal IOLs.
