Understanding Cataracts and Cataract Surgery
A Visual Guide to Cataracts
Understand what cataracts are, the symptoms they cause, and how modern surgery can restore your clear vision.
What is a Cataract?
A cataract isn’t a film that grows over your eye; it’s the natural lens inside your eye becoming cloudy over time. It’s a normal part of aging. The diagram below shows how a cataract scatters light, turning a sharp scene into a blurry, faded view.
Clear Vision
A healthy lens focuses light clearly.
Vision with a Cataract
A cloudy lens blurs and yellows your vision.
Common Symptoms to Watch For
Because cataracts develop slowly, you might not notice the changes at first. Look out for these common signs.
Cloudy Vision
Faded Colours
Glare & Halos
Poor Night Vision
Frequent Rx Changes
Double Vision
The 15-Minute Surgical Solution
Cataract surgery is a safe, quick, and highly effective day procedure that permanently replaces your cloudy lens.
1. Preparation
Your eye is completely numbed with drops. You’ll be relaxed and comfortable, feeling no pain.
2. Removing the Cataract
The surgeon makes a tiny incision to gently break up and remove the cloudy lens.
3. Inserting the New Lens
A clear, artificial Intraocular Lens (IOL) is folded and inserted, unfolding into place.
4. Completion
The tiny incision is self-sealing (no stitches needed) and a protective shield is placed over your eye.
Choosing Your New Lens
You have a choice for your new, permanent lens. Discuss with your doctor which option best fits your vision goals and lifestyle.
Monofocal
Provides clear vision at a single fixed distance (usually far). This is the standard, reliable choice.
Best for:
- Excellent distance vision.
- Patients happy to wear reading glasses.
Toric
Corrects both your cataract and your astigmatism in one step for sharper vision.
Best for:
- Patients with astigmatism.
- Clearer distance vision than monofocal.
Multifocal / EDOF
Advanced lenses designed to provide clear vision at multiple distances (near, mid, and far).
Best for:
- Reducing dependence on glasses.
- Active lifestyles.
