1. Cataract FAQs

  • A cataract is the clouding of the natural lens inside the eye. As the lens becomes cloudy, vision gradually becomes blurry, dim, or hazy, similar to looking through frosted glass.

    • Blurred or cloudy vision

    • Difficulty seeing at night

    • Glare or halos

    • Needing brighter light to read

    • Frequent glasses prescription changes

    • Colours appearing faded or yellowed

  • When they affect everyday tasks such as driving, reading, or night vision. There is no need to wait until a cataract becomes “ripe.”

  • The cloudy lens is removed and replaced with a clear artificial lens (IOL). The procedure takes 10–20 minutes and is usually performed under local anaesthesia.

    • Monofocal (clear distance vision)

    • Toric (astigmatism correction)

    • Multifocal (distance + near)

    • EDOF (enhanced range of focus)

  • This depends on the lens selected. Monofocal lenses may require reading glasses, while toric and multifocal lenses can reduce dependence on glasses.

  • Yes, both eyes can be treated on the same day when clinically appropriate. Some patients choose separate procedures; the approach is tailored to your preference and clinical needs.

  • Most patients can drive once their vision meets DVLA driving standards, often within a few days.

  • Yes, major insurers cover cataract surgery, checks, and follow-up. Self-pay packages are also available.

    • Flashes of light

    • New floaters

    • Shadow/curtain in vision

    • Sudden distortion

    • Sudden blurred vision

    • Loss of central vision

    These signs require urgent assessment.

  • Detachment occurs when the retina peels away from the back of the eye. It is a medical emergency requiring prompt specialist treatment.

    • Vitrectomy

    • Scleral buckle

    • Gas bubble (pneumatic retinopexy)

  • Floaters are small specks or strings in your vision. A sudden increase—especially with flashes—may signal a retinal tear and needs urgent examination.

  • A disease affecting the central retina:

    • Dry AMD: gradual vision changes

    • Wet AMD: rapid changes requiring urgent treatment

  • With anti-VEGF injections to reduce swelling and stabilise vision.

  • A thin layer of scar tissue forming on the retina, causing blurred or distorted central vision.

  • If visually significant, vitrectomy with membrane peel improves clarity and reduces distortion.

  • A small opening in the central retina leading to lost or blurred central vision.

  • Vitrectomy surgery with gas bubble placement; in some cases, face-down positioning helps the hole close.

  • Recovery varies, but many patients experience meaningful improvement, especially when treated early.

  • You may need to:

    • Avoid flying if a gas bubble is used

    • Avoid strenuous activity

    • Maintain special head positioning if advised
