Doctor’s Answer (1)

Cataract surgery is not always an elective procedure. Occasionally, a cataract may progress very rapidly to cause severe visual impairment, as well as acute glaucoma.

In these situations, the cataract needs to be removed urgently. In most other cases, cataract surgery is elective because cataract progression is usually very gradual.

You should choose to have your cataracts removed when your vision deteriorates to a stage that it affects your quality of life. This is very dependent on each individual, your occupation and activities you like to do.

If you experience blurring of vision, doubling of vision, dimming of vision or decrease in contrast, especially in low-light conditions, that is preventing you from enjoying your favourite hobbies or sports, you should get your eyes assessed for the need for cataract removal.

If your cataracts are not removed, you will suffer from increasingly poorer vision and in the most severe scenario, the cataract may ‘explode’ to cause an acute glaucoma, which leads to eye redness and pain.

Another important point to note is that cataract removal of a very mature or ‘hard’ cataract is more difficult and complicated than cataract removal of a less dense cataract. Hence, it is ideal to remove it before it gets too ‘hard’.

Types of Cataracts, Prevention, and What Happens After Surgery

You could call them one of the defining traits of the ‘getting old’ process. Cataracts are the clouding that occurs in the lens of the eye which leads to a decrease in vision. It’s a common condition among Singaporeans (as well as people around the world). 

Cataracts often develop slowly with symptoms such as blurry vision with halos around light or seeing faded colours.

Dr Jimmy Lim Wei Kheong is the Medical Director and a Senior Consultant at JL Eye Specialists. He is an eye surgeon who specialises in cataract, refractive surgery (LASIK), cornea, and general ophthalmology. On DoctorxDentist Sessions, he answered questions related to cataracts, from prevention measures to solutions. Here's what the doctor had to share.

A major cause of blurred vision in the elderly is cataracts. A normal condition in old age, it results in the clouding of the lens which can ultimately affect vision.
