Are you noticing cloudy or blurred vision?
Cataracts can cause blurry or cloudy vision, which can be frustrating, especially if it’s affecting your daily activities. While many cataracts develop slowly and may not need immediate treatment, others may require surgery to restore clarity and comfort in your vision. Here’s how to know when treatment might be necessary:
When to treat cataracts
If these issues are affecting your daily activities like driving, reading, or working, it might be time to consider cataract surgery:
Blurry or cloudy vision
Increased sensitivity to light
Difficulty reading or seeing at night
Frequent changes in glasses prescription
Seeing halos around lights
At our central London clinic, you’ll receive a thorough assessment and treatment to restore your vision.
When to treat vs monitor
When to consider cataract surgery
- Cataracts are noticeably impacting daily activities like driving or reading
- Vision changes are progressive or causing significant discomfort
- Glasses no longer provide adequate correction
When to monitor:
- Symptoms remain mild and manageable with current vision aids
- Daily activities continue without major difficulty
- Cataract progression is slow or stable
Professor Tom Williamson will guide you in determining whether surgery is right for you, or if monitoring your condition is the best option.
