Cataract surgery: What is it, how does it work?

I often get asked this question and it’s definitely a tough one to answer as it is quite a complicated process! When I was first learning about laser eye surgery and didn’t know what was going on, I’d ask the team at laser cataract adelaide for their advice on how best to explain the process.

Here’s what I came up with as the best way to explain the complicated process involved with eye surgery – particularly cataract surgery and how it works.

What is a cataract?

The lens in each of our eyes is naturally clear, however when it becomes clouded or opaque it is referred to as a cataract. This results in blurred vision and can cause irritation and sight issues for patients.

How are cataracts caused?

The most common cause of cataracts is simply old age. They are generally the result of the natural aging process however some people are born with them or develop them in younger years as a result of injury or drug use.

There are some studies that indicate those with diabetes could also be at a higher risk of developing cataracts.

What is Cataract surgery?

Cataract surgery is a very common procedure and one of the most frequently performed operations. Its main purpose is to clear up the cloudiness and rebuild vision.

In surgery, the clouded lens is taken out and replaced by a clear manmade lens. The technique used in cataract surgery is called phacoemulsification – this is also known as small cut cataract surgery.

After surgery, it’s highly normal to be more sensitive than normal to light and most medical experts will recommend wearing sunglasses or avoiding bright lights immediately after. This is due to the fact that mild tearing can occur during surgery.

Is Cataract surgery safe?

All surgery has an element of risk so it’s always best to fully discuss your medical history and any concerns with your doctor. However, 98% of cataract surgeries are completed every year without any serious complications.

The procedure is relatively simple and good results are very common with clear vision achieved for the patient within a matter of days.

As I mentioned before, if you’d like to know a bit more about cataract surgery, the best place to visit is the professionals at who is where I learnt everything I know from!

How to know when you need eye surgery

In the past 65 years there have been huge leaps in the field of eye surgery and dramatic results can be achieved for those with a variety of sight issues.

Whereas glasses and contact lenses are still widely popular, there are multiple other options for those wanting to invest long term in their eye sight and explore surgical procedures that could help them.

It would have been unimaginable 100 years ago for someone with poor eyesight to one day be able to see clearly however laser eye surgery has developed to such an extent that incredible results are achieved on a regular basis.

How does Eye Surgery work?

Laser Energy helps to reshape the curvature of the eye’s front surface called the cornea. This helps to change the way that light rays enter the eye. In order to carry out eye surgery, surgeons will need to create a flap in the cornea of the eye.

In addition, artificial lenses can be inserted into the eye to refocus light rays and improve vision.

Is Eye Surgery right for you?

If you’re tired of always having to wear eye glasses or contact lenses and want to correct your vision once and for all, you may be considering eye surgery. It’s important to be fully aware that any surgery involving the eyes does carry a certain level of risk and after effects of eye surgery can include vision disturbances and dry eyes.

Generally, eye surgery is most appropriate for people with moderate degree:

  • Myopia (near sightedness) – this means the patient can see nearby objects yet finds distant objects harder to identify or blurred
  • Hyperopia (far sightedness) – this means the patient can easily identify distant objects yet finds nearby objects blurry and out of focus.

Does Eye Surgery help with Presbyopia?

Presbyopia refers to the loss of ability to focus on nearby objects and commonly occurs in older patients, particularly those over 65 years old. Small print such as newspapers or restaurant menus can become increasingly difficult to read.

Many surgeons actually recommend those with presbyopia to avoid laser eye surgery and instead consider correcting vision by monovision instead.
