Cataract is the most common cause of blindness and visual impairment worldwide and is conventionally treated with surgery. It refers to a clouding of the natural crystalline lens inside the eye, which causes a decrease in vision. It typically occurs due to ageing, although other causes may include use of steroids or other drugs, exposure to radiation or toxins, associated health problems such as diabetes, hypertension and eye injuries, or genetic, congenital or nutritional factors.

To restore vision, surgery is performed to remove the cataract followed by insertion of an artificial intraocular lens (IOL). Minimally-invasive, small incision, Phacoemulsification is now the standard surgical treatment for cataract. It involves using ultrasound energy to emulsify then aspirate the cataract through a very small self-sealing wound. To further enhance intra-operative precision, selected patients may be suitable to undergo the cutting-edge “bladeless”, Femtosecond cataract surgery. The insertion of an IOL during cataract surgery gives patients an opportunity to customise their refraction. They can choose from a variety of IOLs with different refractive capabilities at different distances including monfocal, bifocal or trifocal IOLs. Astigmatism may also be reduced at the time of surgery using a toric IOL, surgical wound positioning or concomitant astigmatic keratotomy incisions on the cornea. In addition, our centre also handles more complex forms of cataracts including congenital cataract or secondary cataracts due to trauma (with lens subluxation or dislocation), inflammation or steroid use.

Cataract (cloudy lens) can affect vision significantly.
