A patient with cataract will eventually find it hard to read, or drive a car - especially during the night. Even recognizing people's face and seeing expressions becomes difficult. Cataracts are not usually painful. The patient’s long distance vision is more affected initially.

Cataract developes in the lens; the lens become cloudy inside the eye - which is normally clear. Cataracts can develop in one or both eyes. If they develop in both eyes, one will be more severely affected than the other. A clear lens allows light to pass through to the back of the eye, so that the patient can  see  well-defined  images.


If  a  part  of  the  lens becomes opaque light does not pass through easily and the patient's vision becomes blurry - like looking through cloudy water or a fogged-up window. The more opaque (cloudier) the lens becomes, the worse the person's vision will be.


As cataracts develop very slowly most people do  not  know  they  have  them  at  first.  However,  the clouding progresses and vision will gradually get worse. Stronger lighting and eyeglasses can help improve  vision.


Nevertheless,    the  vision impairment affects the patient’s ability to carry out everyday tasks. At this point the individual will  need  surgery.  Fortunately, cataract  surgery is usually a very effective and safe procedure.

Signs & Symptoms

(i)   Age related cataracts - they appear later in life; the most common form


(ii)  Congenital  cataracts  (childhood  cataracts)

        These  may  be  present  when  the  baby  is  born, or shortly after birth. Cataracts may also be diagnosed in older

        babies and children - these are  sometimes  referred  to  as developmental, infantile or juvenile cataracts

Cataract Surgery

The cloudy lens is removed from the eye and an artificial  clear  plastic  lens  is  put  in  its  place  -  an intraocular implant (intraocular lens).


In most developed  countries,  and  a  growing  number  of developing  countries,  cataract  operations  are performed as keyhole surgery. The patient will be given a local anesthetic. He/she will not usually have to spend the night in hospital.


The operation is  commonly  known  as  phacoemulsification or phaco extracapsular extraction. Laser surgery is not used for cataract procedures.



Micro Incision Cataract Surgery (MICS)

Micro Incision Cataract Surgery (MICS) is the most advanced, state of the art surgical technique for treating cataracts. Now only tiny incision measuring 1.80-2.00mm is required to perform the surgery. Using a technique called phacoemulsification, an ultrasound probe is used to safely breakup the cataract. The cataract is then removed with suction and the intraocular lens (IOL) is then inserted into the eye through a 1.81 mm incision. The whole procedure takes approximately 20-30 minutes.

The benefit of MICS:


1.   Micro Incision (Smaller Incision)

     ► Smaller incision of 1.80-2.00mm can prevent unwanted interferences to vision known as astigmatism.
           (The larger incision used for standard cataract  surgery may cause unwanted changes to the eye, known as

           surgically induced astigmatism)


2.  Less Pain

     ► Less invasive, a more gentle surgery providing the best comfort


3.  Faster Healing

     ► Faster healing and recovery time, thus decreasing the chances of infection
