Cataracts are a common age-related eye condition that causes the lens of the eye to gradually become cloudy. Fortunately, cataract surgery is one of the most commonly performed and safest procedures in the world. But one question often comes up among patients: will cataract surgery change my vision? The answer is yes... and that's good news!
What is a cataract?
A cataract develops when the lens, a clear lens located behind the iris, becomes cloudy over time. This can lead to:
• Blurred or cloudy vision
• Increased sensitivity to light
• Difficulty seeing at night
• Colours that appear dull or yellowed
The only way to treat cataracts is to remove the clouded lens and replace it with an artificial intraocular lens (IOL).
How does cataract surgery change vision?
The goal of the operation is to restore clear vision, and in most cases, the change is successful. Here's how your vision may change:
1. Sharper, brighter vision
Once the cataract is removed, light can once again pass freely through the lens. Most patients notice an immediate improvement in the sharpness of their vision and brighter colours.
2. Correction of existing vision
Thanks to modern technology, intraocular lenses can be chosen according to the patient's visual needs. Some lenses can correct:
- Nearsightedness or farsightedness
- Astigmatism
- Presbyopia (with a multifocal lens)
As a result, many patients have less need for glasses after surgery. Some even regain near-perfect distance vision.
3. Adapting to a new perception
It is normal for the brain to need a few days to a few weeks to adapt to the new vision. Sometimes patients find that their perception of depth or colours seems different. This usually fades quickly.
What do you need to know before the procedure?
Before surgery, a comprehensive evaluation will determine:
- The degree of cataract
- The type of intraocular lens best suited to your needs and lifestyle
- Your expectations for vision correction
It is important to discuss your daily activities (reading, driving, sports, etc.) with your optometrist in order to choose the lens that will offer you the best quality of life after your cataract surgery.
Yes, cataract surgery changes your vision, but in a good way. It usually restores clear, sharper vision, and sometimes even better vision than before. Like any medical procedure, it carries minimal risks, but the benefits to your quality of life are generally significant.
If you have symptoms of cataracts or questions about surgery, don't hesitate to consult an optometrist. A personalized evaluation will help you understand what to expect from the procedure and make the best choice for your eyes.
