Cataract surgery is a procedure to remove the lens of your eye and in most cases it is replaced with an artificial lens. Normally the lens of your eye is clean. Cataracts cause the lens to become cloudy, which eventually affects your vision.
15 facts you should know about cataract surgery
If your vision is blurred due to cataracts problem, your eye doctor may suggest surgery to remove the lens of your eye and replace it with an artificial lens. This is a normal and safe cataract eye procedure, and when it is done, you will be able to see better.
1. What time should my cataract be removed?
Traditional cataract surgery was performed when the patient experiences vision loss. We now consider subtle changes in vision such as loss or reduction of contrast sensitivity and colour perception. It is possible to notice a loss of colour perception in low-contrast environments (e.g., night). At night, you may notice a decrease in your ability to see colours. These are early warning signs that your vision is being affected by cataracts. You may need to have surgery.
2. Do I need to be able to see my eye doctor?
This was how cataracts were removed in the past. We now use laser and ultrasound technology to cut the cataract into smaller pieces. This means that it is easier to remove a soft lens (e.g. To aid in the fragmentation process, we use immature cataracts. Actually, patients who have a cataract that is not yet mature are likely to experience shorter recovery times and shorter hospital stays.
3. Is it painful?
Cataract surgery does not cause pain. Patients describe feeling a slight pressure around their eyes. We may administer local anaesthesia via drops or perform small anaesthetic blocks around the eyes in certain cases.
4. What is the waiting period for driving after having cataract surgery?
Patients can drive within 48 hours of the surgery. However, most patients feel more comfortable driving once they feel confident. Avoid driving long distances for the first week after surgery as your eye may feel sore.
5. What is the best time to resume regular chores like gardening or cooking?
Most patients are able to resume their normal activities such as gardening and cooking within one day after a cataract removal. However, it is up to each individual. After the surgery, you should take special care not to cause irritation. In windy conditions, dirt and dust.
6. What time can I resume swimming?
To reduce infection risk, it is best not to swim for at least the first month following surgery. Problem is, pools can be full of germs and viruses that could infect your eye within the first month. For the first week, it is not recommended to do a lot of gym work. Gentle walking or treadmill use is fine.
7. What date will I be able to see the results of my cataract surgery?
In most cases, the visual effects of a cataract surgery are visible almost immediately. But, every patient and cataract is different, so it may take some time for patients to notice the difference.
Your vision may fluctuate after the surgery, but should stabilize within one month. You may experience delayed healing if you have diabetes or a co-existing medical condition.
8. My friend had her cataracts removed. She no longer wears glasses. Is that possible?
Presbyopia can be corrected during cataract surgery with a variety of options. Multifocal intraocular lens (IOLs), which can correct near and distant vision, are now available. Trifocal IOLs, on the other hand, correct vision at near, intermediate, and far distances. Trifocal intraocular lenses (IOLs) are the best choice if you want to be as independent as possible from glasses. Some patients can even get rid of all their glasses with trifocal IIOLs.
Monovision lenses, which can be used to set one eye for near vision and one for distance vision, can also be used. You can also have both eyes set up for distance vision while still using a pair or reading glasses. All depends on what your needs are and how your eyes work. Before you have any surgery, it is important to understand the pros and cons of each option.
9. Can astigmatism be treated?
Astigmatism refers to a refractive error in which the cornea or lens of an eye curves irregularly. Astigmatic people have blurry vision due to the fact that the light rays of the sun do not focus on one spot on the retina at their back. Astigmatism may also be caused by shortsightedness, longsightedness, or both.
10. I have herpes in one eye. Can my cataract be removed?
The herpes virus can become a permanent infection in the eye. It can also reactivate after cataract surgery. To prevent complications from the virus, you will need to take post-operative antiviral medication. The usual duration of the medication is four weeks.
11. I have glaucoma – is it safe to have my cataracts removed?
It is possible to have the surgery without any problems provided that the glaucoma has been controlled prior to the procedure. To improve fluid drainage, we now offer the option for patients to have a micro-stent (iStent injection) placed at the time they undergo cataract surgery. The iStent can help reduce the need for glaucoma medication. In many cases, patients are able to stop using eye drops entirely.
12. I have keratoconus – can I still have my cataracts removed safely?
After cataract surgery, patients with keratoconus are very happy. Many patients find they can get rid of their contacts completely. Astigmatism is one of the symptoms of keratoconus. This can be treated at the same time as the operation (see question 9).
13. Are cataracts ever able to come back after being completely removed?
In the sense that cataracts do not come back, a cataract surgery is only performed once. Cataracts don’t ‘grow’ and the replacement lens will not transform into a cataract.
Sometimes, however, a thin layer of scar tissue may form behind the lens implant. This is known as posterior capsule opacification. It can be easily removed in a painless laser procedure at the clinic (YAG Laser Capsulotomy).
14. I have had a corneal implant in the past. Is cataract surgery safe?
Patients who have had corneal transplants are able to have their cataracts removed very safely. Patients who have had cataract surgery should be aware of the possibility of developing rejection. This can be treated with steroid drop. A second graft may also be needed due to the possibility of damage to the cornea.
15. After the operation, will I need stitches in my eye?
Modern cataract surgery doesn’t require stitches. It is a keyhole procedure, and the main incision measures approximately 2 mm. Once the intraocular lens has been placed in the eye, it is inserted through a thin cartridge. One or two small stitches may be required in some cases of complex cataract surgery. These can be removed after the tissue has healed and is a few weeks later.
