Flashes and Floaters
What they mean, and when to act. Flashes and floaters are usually harmless — but a sudden change can be an early warning sign worth checking promptly.
Book a consultationFlashes and floaters are common visual symptoms that many people experience, especially as they age. Floaters appear as tiny spots, threads, or cobweb-like shapes that drift across your vision, while flashes are brief bursts of light, often seen in your peripheral vision.
What causes them?
Most flashes and floaters are caused by the natural shrinkage of the vitreous gel inside the eye, which can tug on the retina as it moves. This is usually harmless and very common — but it is important to know when a change needs a closer look.
When to act quickly
A sudden increase in floaters, new flashes, or a curtain-like shadow moving across your vision could be an early warning sign of a retinal tear or retinal detachment — a serious condition that requires urgent attention. If you notice these symptoms, please don't wait to be seen.
Caught early, retinal tears are very treatable
If a tear is found early, it can often be treated with laser or cryotherapy to prevent it progressing to a detachment. A prompt eye examination is the best way to rule out anything more serious.
If you experience new or worsening flashes and floaters, don't ignore them — early assessment can prevent vision loss.

General Eye Health
How often should I have my eyes checked?
We recommend a comprehensive eye examination every one to two years, even if you are not experiencing any vision problems. Patients with diabetes, those over 60, or those with known eye conditions may require more frequent monitoring to maintain optimal eye health.
What are common signs I should see an eye specialist?
Symptoms such as blurred vision, flashes of light, new floaters, eye pain, sudden loss of vision, or difficulty seeing at night may indicate a serious condition. Early assessment by an ophthalmologist can make a significant difference in treatment outcomes.
Can eye diseases be prevented?
While not all eye diseases are preventable, many risks can be reduced with regular check-ups, management of systemic conditions such as diabetes and hypertension, UV eye protection, and maintaining a healthy lifestyle. Early detection remains key to preserving vision.
What is the difference between an optometrist and an ophthalmologist?
Optometrists are trained to assess vision, prescribe corrective lenses, and manage certain eye conditions. Ophthalmologists are medical doctors with advanced training who diagnose and treat all eye diseases and perform surgical procedures when required.
Do I need a referral to see an ophthalmologist?
While a referral from your optometrist or general practitioner can be helpful, it is not always necessary. You are welcome to contact our clinic directly to arrange an appointment.
Eye Surgery
Is cataract surgery painful?
Cataract surgery is generally painless. It is performed under local anaesthetic, ensuring you are comfortable throughout the procedure. Most patients experience a smooth and rapid recovery, with significant improvements in vision within a few days.
How long does cataract or vitrectomy surgery take?
Cataract surgery typically takes around 20 to 30 minutes. Vitrectomy surgery may take longer, depending on the complexity of the case, usually between 45 minutes and two hours. Both procedures are commonly performed as day surgeries, allowing you to return home the same day.
How long does it take to recover from vitrectomy surgery?
Recovery varies according to the underlying condition and surgical approach. Generally, patients notice gradual vision improvement over several weeks. Our team will provide detailed post-operative instructions to support your healing and optimise your outcome.
Will I need to wear glasses after cataract surgery?
Many patients enjoy significantly improved vision after cataract surgery, although some may still require glasses for activities such as reading. Advanced intraocular lens options are available to further reduce dependence on glasses, and we will tailor recommendations to suit your lifestyle and needs.
