What does cataract surgery involve?
You will have an initial appointment where the ophthalmologist will assess your eyes. The ophthalmologist may also be able to correct your short- or long-sightedness so that you do not need to wear your glasses as much after the operation as you did before.
Most cataract operations are done using a local anaesthetic, it takes around 20 minutes.
Your eye will be covered to protect it from knocks for a few days after the operation. You will be allowed to go home the same day but must not drive.
What is a lens implant?
When the cloudy lens has been surgically removed it is replaced by a plastic lens implanted in the eye so that it can focus properly. This plastic lens is rolled up so that it can be inserted into the eye and placed in the lens capsule, where it springs into position. Usually, the new clear window greatly improves the quality of vision. Once you have had the cataract removed, it will not grow back. Once the eye has healed a change of spectacles is usually required. Occasionally your doctor will decide the eye is not suitable for a lens implant. In these cases, contact lenses or special spectacle lenses will be prescribed instead.
Will I need new spectacles after my cataract operation?
Your eyesight will settle down in a few weeks. You will probably find that your glasses will need changing after the operation, so you will need to see your optometrist again for an eye examination about six weeks after the surgery.
You may find that it takes a few weeks to adapt to your vision with new glasses after cataract surgery. This is normal, and is due to your brain adapting to a different prescription.
