What is cataract?

Cataract is a condition where the natural lens of the eye becomes cloudy and blocks out light from entering the eye. It is one of the top 5 causes of blindness in Singapore and occurs due to ageing, sun exposure and/or chronic diseases like diabetes.

Why do I need to check for cataract? How can I check if I have cataract? 

Doing a check with an eye specialist allows any signs of cataract to be detected and treated early.

With our Basic Cataract Check package, Dr Loh can assess your cataract thoroughly and advise you on:

  • how serious is your cataract(s);
  • if and how you can delay progression of the cataract(s);
  • when and how your cataracts can be treated.

When is cataract surgery necessary?

With the latest techniques of cataract removal and the new generations of premium lens implants, you now don’t have to wait until your cataract is “ripe” or very thick. Cataract surgery is now recommended if the extent of the cataract in your eye(s) affects the quality of vision which you need for your daily activities and work.

How is cataract surgery done?

Dr Loh uses advanced and safe techniques for the cataract surgery.  The surgery is done by Dr Loh as a day surgery procedure in operating theatre with the surgery lasting typically about 45 minutes. The patient is placed under local anaesthesia mild sedation under constant monitoring by an Anaesthetist doctor so the patient will not feel any anxiety, pain or discomfort during surgery.

The surgery involves 2 steps:

  1. Removal of the cataract; and
  2. Insertion of intraocular lens implant.

Step 1: Removal of cataract

The preferred method of removing a cataract is by phacoemulsification (using ultrasound to break up the cataract), as it is established to be safer and have lower risks of complications. Dr Loh uses the latest phacoemulsification technology from leading companies such as Alcon (Infiniti/ Centurion/ Constellation) or Bausch & Lomb (Stellaris).

Q: Does Dr Loh use bladeless/ femtosecond laser-assisted surgery to remove cataracts?

A: Cataract surgery can be also be done with the assistance of femtosecond laser.

For most cataract cases, cataract surgery by phacoemulsification can be a safer and/or more cost-effective option. Dr Loh will evaluate in detail with each patient to determine if cataract surgery by phacoemulsification or femtosecond laser-assisted surgery is more suitable.


Step 2: Insertion of intraocular lens implant

Although our lens implants are reasonably priced and affordable, Dr Loh uses only intraocular lens from premium brands to tailor to each patient’s individual needs and achieve best possible sharpness and quality of vision :
