CATARACTS

If you are interested in seeing what having a cataract looks like, here is a great link to the sight simulator on the Fred Hollows Foundation website, which offers you a sense of what it is like to have  visual impairment.

What is a cataract?

A cataract (Greek, meaning waterfall) is a cloudiness or opacity of the lens inside your eye. 

  

When we are young, the lens is clear, and can change shape so we can see up close.

As we age, the protein structure in the lens changes, so that the lens becomes stiff and then cloudy (like an egg white when it is cooked). In the early stages, we have trouble seeing up close, so that we need reading glasses. As the process progresses, we can experience glare in bright lights or while driving at night, with trouble reading in dim light.

 

In the early stages of cataract, glasses may help for reading, and then for distance. As the cataract becomes cloudier, you may reach the stage where you cannot see as well as you would like, even with glasses. This is when we start considering cataract surgery as an option.

What is cataract surgery?

As the cloudy lens or cataract is inside the eye, surgery involves making cuts in the eye, removing the cloudy lens, and replacing it with a clear plastic lens, so that the eye can see clearly.

 

When do I need cataract surgery?

You almost never need cataract surgery. The cataract is just a change in the structure of your lens. It cannot harm your eye, except in very rare cases. The only time you need surgery is if your vision has dropped to the point where you can no longer drive, but even then, you can choose to stop driving, if you really don’t want surgery! But the benefits of the surgery are great, so you may well want it!

 

Will I be able to see without glasses?

The lens power is usually selected so that your eye is in focus for distance. You will usually still need reading glasses to see up close and may need glasses to fine tune your distance vision.

 

There are two ways to see clearly without glasses:

  • Monovision, in which one lens is in focus for distance, and the other lens is in focus for near. This means that only one eye is in clear focus at any point in time and most people prefer to have their two eyes working together.

  • Multifocal lens implants are also available. They are more expensive and while many people are happy with them, they can cause problems with unclear vision, glare, haloes and trouble night driving (like having cataracts!).

 

What are the risks and benefits of cataract surgery?

 

Before deciding whether to have cataract surgery, you will need to discuss with your doctor all the risks and benefits involved, to find out what is the right decision for you.

 

  • Benefits of the surgery include clearer, brighter vision and the ability to see in the distance without glasses. If you were long-sighted or short-sighted before the operation, this can be a very happy experience.

  • The risks of the surgery are small, and the surgery is successful in over 95% of cases, but not 100%. The risks do include haemorrhage and infection, potentially with loss of vision and even loss of the eye, so it is important to understand that surgery should only be considered if you are unhappy with your vision, even with the use of glasses.

  • This is why we don’t operate on both eyes on the same day...just in case there are any problems.

 

What happens on the day of cataract surgery?

The operation is microsurgery, performed as a day case procedure in hospital, under local anaesthetic with sedation. We do it this way so that a team of people can care for the whole of you, while doctor focusses her full attention on you and your operation.

The operation only takes minutes, but the whole process takes hours. Drops are put in your eyes beforehand to dilate the pupil and we like to make sure you are rested beforehand and recovered afterwards before we let you go home. The anaesthetic can affect your vision for several hours afterwards, which is why you need assistance. You will need someone to drive you to the hospital and back home again and to care for you afterwards.

What can I do after cataract surgery?

There is little to no pain afterwards, and you can usually see clearly by the next day, but is important to take at least a week off work and to care for yourself tenderly in the weeks after the surgery, to allow the eye (and you) to rest and heal. You can read, watch TV, go for gentle walks and potter around the house, but no heavy lifting, bending, straining or swimming for a couple of weeks.

Anne sees you again the next day, then a week later and at the end of a month, and you are to use eye drops this whole time. If you used to wear strong glasses, these will need to be changed, but we wait a month for the eye to heal completely before doing the final glasses test.
