Cataract Surgery Expectations

Before surgery

Before the surgery, we will perform some essential tests to choose the right prescription (power) and type of IOL for you. The tests include:

• Measuring the shape of the eye (topography)

• Length of the eye (biometry) – a specialized test to measure the power of the IOL to be placed in your eye. It can be done with contact ultrasound, immersion ultrasound and laser-interferometry (shown below).

Dr Tan may advise you to consider monovision as an option for your vision correction. Click here to find out more.

Eyedrops need to be applied one day before your operation and you will need to fast for 6 hours before your surgery.

It is important to note that the tests’ results are only valid for 6 months.

During surgery

• Surgery will be done at Novaptus Surgery Centre.
• At the Day Surgery ward, dilating drops will be instilled into your eyes to enlarge your pupil.
• Surgery usually lasts about half an hour.
• You will be sedated by an anaesthetist and will not feel pain during the surgery.
• The area around your eye will be washed and cleansed. A local anaesthetic will be given to numb the nerves in and around your eye.
• After the operation, an eye pad will be placed over your eye. You will rest for about 3 hours.

Dr Tan’s medical team will watch for any problems such as an increase in eye pressure or bleeding. Most patients who have cataract surgery can go home the same day. You will need someone to drive you home.

After surgery

1 day post-op	Improved vision within a day or two after surgery for the majority Normal activities such as reading or light work can be resumed after eye pad is removed Common symptoms after cataract surgery include: Itching Mild discomfort Some fluid discharge Temporarily sensitive to light and touch Inform Dr Tan should you have any discomfort. Mild discomfort should usually disappear after 1 to 2 days.
1 week post-op	Periodic check to check residual power and progress of healing May have itching, mild discomfort and some fluid discharge – normal after cataract surgery
4 to 5 weeks post-op	Periodic check to check residual power and progress of healing You are required to use eyedrops for 5 weeks after surgery to help with healing and decrease the risk of infection. Dr Tan and his team will inform you on how to use your eyedrops, how often to use them, and what effects they can have. You will need to wear an eye shield or eyeglasses to help protect your eye. Avoid rubbing or pressing your eye. At home, try not to bend your head below your waist to pick up objects on the floor. Do not lift any heavy objects. You can walk, climb stairs and do light household chores.
Within 6 weeks	Vision continues to improve until best vision is reached Healing completed in most cases

The above estimated visual recovery is applicable for patients who underwent phacoemulsification surgery.
