What is cataract?
The natural lens in the eye is normally transparent and allows light to focus on the retina at the back of the eye enabling a clear image.
Cataract is formation of opacity in this lens of your eye. This causes blurred vision, haloes around light and glare in headlights and sunlight.
What causes cataract?
The most common cause is age-related changes to the lens. As a result, it is commonly seen after the age of 60. Occasionally cataract can develop at a much younger age due to the use of steroid, injury to the eye or metabolic disorders.
What is the treatment for cataract?
What different types of intraocular lenses are available?
The Standard monofocal lens will allow clear focus at a fixed distance. This lens is included in the cost of your Cataract procedure.
The Premium intraocular lens will provide focus at all distances (multifocal IOL), correct astigmatism (toric IOL) or do both (multifocal toric). There will be an extra charge for this lens. Please refer to Premium IOL page for more information.

What are the complications of cataract surgery?
Complications after the operation
- Prolonged inflammation of the eye
- Infection (Endophthalmitis)
- Increased pressure in the eye (Glaucoma)
- Waterlogging of cornea (Corneal Oedema)
- Detached retina
- Swelling/Fluid at the back of the eye in the retina (Macular Oedema)
- Droopy eyelid (Ptosis)
- Double vision or ghosting
- Displacement of intraocular lens
- Misshapen pupil
- Thickening or clouding of lens capsule (posterior capsular opacity)
- Unexpected refractive outcome – This means spectacle prescription much different from what was planned for. This may lead to having to wear spectacles or contact lenses all the time.
- Seeing new floaters or worsening of pre-existing floaters.
- Visual disturbances (Dysphotopsia) – Seeing flashing lights, an arc of light in the corner, glare etc.
Complications during the operation
- Break in the lens capsule (Capsule rupture)
- Prolapse of vitreous jelly (Vitreous loss)
- Loss of part or the whole lens to the back of the eye
- Bleeding behind the retina causing permanent visual loss (Expulsive haemorrhage)
- Injury or trauma to the intraocular structures
- Enlargement of cut requiring stitches
