We are asked many questions about cataract surgery so here are the answers to our top 13 FAQs.
Each patient and each eye is different so we take measurements before surgery (called biometry) to establish the correct lens power for each individual eye. The lens implants we use come in different types. The two main categories of implant are:
These provide either good distance vision (most common) or good near vision but not both. You would still need glasses to cover either reading (more common) or distance vision depending on which lens type that was put in.
These lenses offer a high probability of achieving spectacle independence i.e. providing you with the ability to see far as well as to read without glasses.
Both these lens types come in toric versions which can correct for astigmatism if present to a high degree.
The procedure takes 10-15 minutes per eye. Due to improvements in safety we are now able to treat both eyes on the same day in certain patients. Otherwise, the worst eye is treated first and the other eye treated subsequently. This will be discussed and decided with you at your consultation with Mr Mearza.
No, we put anaesthetic drops in the eye to numb the surface of the eye for the procedure (so no needles at all!). You may feel some pressure on or around the eye briefly during the procedure. Your eyes may feel tired and gritty for a couple of hours afterwards, but will feel much better the next day.
We advise you go home and rest for the remainder of the day. Ideally you would have at least 48 hours off work too.
After cataract surgery we give you eye drops to use for 4 weeks. The drops include an antibiotic drop to help prevent any infection; 2 types of an anti-inflammatory drops to prevent any redness and lubricant drops to use regularly if your eyes feel tired or gritty.
We have an app which is free to download on your device that will send you notifications when your drops are due so that you never miss a drop.
You will be able to see afterwards, however your vision will be slightly misty for 48 – 72 hours. Depending on what the vision was like before, you may notice a considerable improvement straight away.
Best not to wear eye make up on the day of surgery or for 1 week afterwards, particularly mascara and eye liner.
You can resume light exercise 3 days after treatment, and full exercise 2 weeks after treatment.
You can go swimming 2 weeks after treatment but we recommend you wear goggles as the chlorine in the pool can irritate your eye. After 4 weeks, you can usually swim without any restrictions.
We advise that you avoid air travel for at least a week following surgery.
We recommend avoiding this for the first 48 hours after surgery.
If you don’t have cataract surgery the lens will stay cloudy and over time will get worse. The surgery can be more challenging if the lens becomes too cloudy (or dense) so we often advise people to have them removed as soon as you notice a change in your vision.
We advise that you shower with your eyes closed for 1 week after surgery.
