Cataract FAQ

A cataract is the clouding of the natural lens of the eye. Approximately 25% of people over 65 years of age will have some cataract formation. Cataracts can develop in both eyes but the rate at which they develop in each eye often varies.

Cataracts may develop due to a variety of factors including:

• The natural ageing process
• Prolonged exposure to UV light
• Eye trauma
• Smoking
• Diseases such as diabetes
• Long-term use of some medications (particularly Cortisone)
• Hereditary factors

Common cataract symptoms include, glare, ghosting, multiple images, trouble with near and distance vision and frequent changes in spectacle prescription. You may just notice that your vision is blurred. Your regular eye care practitioner should be able to detect a cataract.

A referral can be sought via your optometrist or your GP and will be required at your first appointment at Wollongong Eye Specialists.

Cataract surgery should be considered when your symptoms interfere with your daily activities or when prescription spectacles no longer provide sufficient visual clarity.

No, cataract surgery is a day procedure and you will be able to return home and rest and recover in the comfort of your own home. It is advisable that a responsible adult is with you for the first 24 hours after surgery.

No, you will need to have a friend or family member drive you home or arrange for alternative transport.

Only one eye is operated on at a time and usually the most affected eye is treated first. The second eye may undergo treatment at a later date depending on your and your surgeons preference.

Visual recovery is rapid, and you can expect to begin to see well 24-48 hours after surgery. Some people may take longer to recover.

Glasses may still be needed for reading and near tasks, depending on the lens type you choose, and your regular eye care practitioner can prescribe these approximately 4-6 weeks following cataract surgery.

An IOL, or intraocular lens, is implanted in the eye to replace the eye’s natural lens when it has been removed during cataract surgery to restore vision by focusing light onto the retina, compensating for the loss of the natural lens. There are several types of IOLs which are used by Wollongong Eye Specialists depending on your visual goals and eye health.

• Monofocal IOLs: Correct vision at one distance (usually far), requiring glasses for near tasks.
• Multifocal IOLs: Provide multiple focal points, allowing for improved vision at near, intermediate, and far distances.
• Toric IOLs: Specifically designed to correct astigmatism.
• Extended Depth of Focus (EDOF) IOLs: Designed to provide a range of vision.
