Cataract Surgery

Do I have Cataracts?

The risk of cataracts increases with age. 78.6% of Singaporeans aged 60 and above have cataracts. Think you have cataracts? Refer to our list of cataract symptoms.

when should I have Cataract surgery?

As cataracts progress, vision becomes increasingly worse. Cataract surgery is recommended when vision worsens to the point where it starts to affect daily activities such as reading, writing and driving.

Do not wait too long to have cataract surgery. Once cataracts have reached the hypermature stage, they become “harder” and more difficult to remove, thereby increasing the risk profile of the surgery.

"4-in-1" Cataract Surgery

Cataract involves the (a) removal of the cloudy lens and (b) insertion of an intraocular lens implant. As a result, cataract surgery is able to treat:

  1. Cataracts
  2. Myopia/Hyperopia
  3. Astigmatism
  4. Presbyopia (lao hua)
There are two types of cataract surgeries:
  • Phacoemulsification
  • Femtosecond Laser-Assisted Cataract Surgery

Both methods are regarded as safe, effective, and established.

Intraocular Lens Implants (IOLs)

There are many different types and brands of IOLs in the market. However, they can be classified into two main types:

Monofocal IOLs

  • IOLs with one focal point
  • Patients can choose between ‘sharp at distance’ or ‘sharp at near’
  • Sharp at near: patients have clear near vision but have to wear glasses for distance vision
  • Sharp at distance: patients have clear distance vision but have to wear reading glasses
  • Able to provide sharp
  • Less incidences of haloes and glares
  • Reliance on glasses

Multifocal IOLs

  • IOLs with more than one focal point – multifocal, trifocal, extended range of vision
  • Patients can choose between ‘sharp at distance’ or ‘sharp at near’
  • Sharp at near: patients have clear near vision but have to wear glasses for distance vision
  • Sharp at distance: patients have clear distance vision but have to wear reading glasses

When Should I go For Cataract Surgery?

In general, it is recommended that one goes for surgery when cataracts begin to cause inconvenience in their daily lives. If you are noticing cataract symptoms, it is best to consult an eye specialist.

At the hypermature stage, cataracts become harder and more difficult to remove. As such, cataract surgery at a hypermature stage poses higher risks.  

Is There Any Way To Prevent Cataracts? Are There Any Other Treatments?

There is no scientifically-proven way of preventing cataracts.

Currently, cataract surgery is the only treatment that is medically-proven for cataracts.

What Causes Vision To Be Cloudy Again After Cataract Surgery?

In some cases, patients are able to achieve good vision after surgery but have increasingly cloudy vision after a period of time. This is because posterior capsule opacification (PCO) has developed. The incidence rate of developing PCO after cataract surgery is rather high. As such, PCO is also known as “after-cataract” or “secondary cataract”.

PCO is caused by the migration, proliferation or differentiation of the residual lens epithelial cells. As a result of PCO, vision becomes more cloudy and hazy. People with PCO will also be more sensitive to bright lights and glares. PCO is easily treatable through a 15-min YAG laser procedure.

Frequently Asked Questions

The improvement in vision after cataract surgery can be experienced within a few days after the surgery and the total recovery may vary with different patients.

Cataract surgery is not painful as the patients are given local anaesthesia before the surgery but you may experience some pressure or mild discomfort. If you are experiencing any discomfort after the surgery you may inform the doctor and he will prescribe you specific eye drops.

Cataract surgery in Singapore normally takes 15 to 30 minutes for each eye. However, more time may be required for pre-operative planning and post-operative monitoring.

While both eyes can be operated on the same day, many surgeons prefer to wait a few days to verify whether the first eye has healed properly before moving on to the second eye.

As with any operation, there are certain risks which are very rare. Infection, haemorrhage, or changes in eye pressure are examples of complications. Before the procedure, your surgeon will go over these risks with you.

Cataract surgery is seen as a permanent remedy. The clouded lens does not grow back once it is removed and replaced with an IOL. However, other age-related vision changes could develop over time.

Many individuals still require glasses following cataract surgery, particularly for reading or other specific jobs. However, premium intraocular lens (IOL) choices can minimise the requirement for glasses in some people. Your ophthalmologist will go over lens alternatives with you and determine which ones are best for your eyesight needs.

Minimally invasive glaucoma surgery consists of a variety of surgical treatments aimed at reducing intraocular pressure in a less intrusive manner than classic glaucoma surgery. MIGS operations frequently result in a shorter recovery period and a lower risk of complications.
