Cataracts

Glasses and better lighting may help in the early stages, but they do not remove the cataract. Surgery replaces the cloudy lens with an artificial one. A femtosecond laser can assist some surgical steps; it is not a treatment that avoids lens surgery. Explore laser-assisted cataract surgery.

It does not have to be ripe. The decision depends on how your vision affects reading, driving, work and other activities, together with the health of your eye and the likely benefits and risks. Monitoring may be appropriate when your symptoms are manageable. Read about timing.

Cataracts usually develop gradually, and monitoring is often reasonable. A very dense cataract can make surgery more difficult, so keep your recommended eye checks. Sudden loss of vision, a painful red eye or new flashes and floaters should be assessed urgently rather than assumed to be cataract.

That depends on your vision with your current glasses and the standards for your licence. Glare and night vision matter as well as reading an eye chart. Discuss any driving difficulty at your assessment; do not drive if you cannot see safely.

Dr Chen removes the cloudy natural lens through a small opening and replaces it with a clear artificial lens, called an intraocular lens or IOL. The lens choice and focusing target are planned with you beforehand. See the procedure step by step.

Usually, yes. Most people return home on the day of surgery after a recovery period. Arrange for someone to take you home and follow the hospital’s instructions about support afterwards. You must not drive yourself home.

Routine cataract surgery usually takes less than 30 minutes in theatre, although complex surgery may take longer. Your overall hospital visit is longer because it includes admission, preparation and recovery. The hospital will confirm your arrival time and arrangements.

Your eye is numbed, and sedation can help you relax when appropriate. Most people are awake and notice light or gentle pressure rather than pain. Tell the team if you are uncomfortable or anxious. Read about anaesthetic options.

Usually, Dr Chen treats one eye at a time, allowing the first eye to settle before the second operation. If both eyes need surgery, the timing is discussed with you and depends on your vision, eye health and circumstances.

There is no single lens that suits everyone. Eye measurements, retinal health, astigmatism and the activities you want to see clearly all matter. Dr Chen will explain suitable options and their trade-offs, including possible halos and the need for glasses. Compare lens choices.

You may. Some lenses mainly focus at one distance; others provide a wider range of focus but involve trade-offs. Even with a lens intended to reduce reliance on glasses, you may still need them for some tasks. Your plan should reflect your priorities and the health of your eyes.

A femtosecond laser can perform selected steps, such as making the opening in the lens capsule and softening the cataract. Dr Chen still removes the lens and inserts the implant. Both approaches involve surgery; suitability and any expected benefit should be considered for your eye. Learn about the laser option.

Other eye conditions can affect lens choice, surgical planning and how much vision improves. Dr Chen assesses the cataract alongside the rest of your eye. If retinal surgery is also needed, combined or staged treatment may be considered. Read about combined cataract and retinal surgery.

Ask about the surgeon’s experience with eyes like yours, your lens options, realistic benefits, risks and who will provide follow-up. Make sure you know where your operation will take place and whom to contact if a problem develops. You should have time to ask questions before deciding.

Vision may begin to improve within days, but it can fluctuate while the eye settles over the following weeks. Recovery varies with the operation and any other eye conditions. Keep your follow-up appointments and ask when it is appropriate to update your glasses.

Driving depends on your vision and your surgeon’s advice, not a fixed number of days. Many people return to desk work within a few days. Walking, reading and screens are generally comfortable early on; swimming, strenuous exercise, dusty work and heavy lifting need individual advice. Follow your written aftercare instructions.

Expect to follow an individual postoperative medicine plan, often including anti-inflammatory drops for several weeks. “Dropless” approaches do not suit every eye and do not mean follow-up is unnecessary. Dr Chen will explain your prescribed treatment. Tell the team if you may have difficulty putting drops in.

The implant is intended to remain in your eye permanently and does not normally need routine replacement. Your vision can still change because of other eye conditions or changes in the lens capsule, so ongoing eye checks remain important.

The removed natural lens cannot develop a cataract again. Sometimes the thin capsule supporting the implant becomes cloudy months or years later. This is called posterior capsule opacification (PCO), and a YAG laser procedure can often clear it. New blur should be assessed to confirm the cause.

Seek urgent eye care for worsening vision, increasing pain or redness, new flashes or floaters, or a curtain or shadow in your vision. Contact your surgical team using your postoperative instructions. If you cannot reach them, attend an emergency department. Do not wait for a routine follow-up.

The cataract surgery guide explains the procedure and recovery, and Lens choices covers implant options. Your visit explains how to prepare for your assessment. Bring your questions so Dr Chen can relate the information to your own eyes.
