Cataract is the cloudiness in the lens which stop people from seeing clearly. The symptoms range from reduced vision/blurred vision, double vision, glare or seeing haloes at night and colour become less bright.
Cataract is usually due to aging process but it can occur at a younger age if someone is born with it (congenital), suffer an eye injury, diabetes and those take steroids.
While there may be someone offering magic eye drops ( yet to be proven its efficacy), cataract surgery is still the ultimate treatment at present. Phacoemulsification is the preferred and common way to remove cataract.
It uses ultrasonic handpieces through a small wound (2.75mm) on the eye and the cataract is aspirated from the eye. It is performed under local anaesthesia, very often anaesthetic drop onto the eye. Patient is awake but usually will not feel any pain. After about less than half an hour, the operation finish and the patient can go home the same day.
During the surgery, an intraocular lens (IOL) will be implanted into the eye. Depending on one’s need, Dr Ho. Shu Fen will discuss the type of lens to be inserted. It can be a monofocal lens with proven track record, well tolerated by most and allow one to see far clearly but require one to wear reading classes to read; toric lens implant to correct high astigmatism, multifocal IOL/lens implant to allow one to see far and near but with higher price. Dr Ho will discuss all the pros and cons of this lens choice with patient so that patients will have clear expectations of what can be achieved.
