How To Prepare For Cataract Surgery: Everything You Need To Know

If you’re booked in for cataract surgery or considering treatment soon, it’s natural to have questions. From knowing what to do the night before, to how long the procedure takes and what to expect during recovery, this guide brings together everything you need to feel informed, confident and fully prepared for cataract surgery.

Things I Wish I Knew Before Cataract Surgery

Many patients say they feel more at ease once they know what to expect. Here are some of the most commonly shared insights from Optegra consultants and patients:

• Cataract surgery is usually completed in under 10 minutes per eye.
• You will remain awake, but the procedure is pain-free thanks to local anaesthetic drops.
• You’ll be able to go home the same day with a protective eye shield.
• Vision can improve within hours, though full healing takes a few weeks.
• You’ll need to use prescription eye drops after surgery and avoid touching or rubbing the eye.

How Long Does Cataract Surgery Take?

Cataract surgery is very quick. The procedure takes about 8-10 minutes per eye. Including preparation and recovery, you can expect to be at the clinic for 2-3 hours in total. If you’re having both eyes treated on the NHS, your consultant will usually schedule the surgeries to be conducted separately, while private patients can and usually do have both eyes treated on the same day.

How Long is the Gap Between Cataract Surgeries on Each Eye?

For NHS patients the wait is usually 4-6 weeks between each eye if the eye meets the vision standards for second eye surgery. Private patients typically wait 1-2 weeks after the first procedure. This ensures your consultant can monitor your progress and tailor the approach if needed.

What to Do the Night Before Your Surgery

Knowing what to do before surgery can help you feel prepared and reduce stress. Here are the most common considerations for the night before your procedure.

Can I Eat or Drink Before Surgery?

Yes, in most cases, you can eat a light meal and drink clear fluids up to a few hours before surgery. You must not drink alcohol before cataract surgery, as it can cause dehydration and affect anaesthesia and other medications. Your clinical team will confirm your personalised instructions during your pre-op assessment.

Can You Be Put to Sleep for Cataract Surgery?

At Optegra we only offer local anaesthetic, as this is the safest option with the quickest recovery. Where patients cannot have local anaesthetic (e.g. cannot lie flat, coughs etc), other hospitals offer general anaesthetic. Each patient is reviewed on a case-by-case basis and after your pre-op assessment you will be informed which option is the best for you.

Can You Wear Contact Lenses Before Cataract Surgery?

If you wear contact lenses, it’s crucial to stop using them at least one week before your surgery. If you are a soft contact lens wearer, we will ask you to keep them out a week before your initial assessment, while hard contact (rigid-gas-permeable) lens wearers will need up to four weeks to ensure accurate pre-operative assessment measurements.

Dressing Comfortably for a Smooth Surgery Day

When getting ready for cataract surgery, aim for comfort and practicality. Wear loose-fitting clothes that are easy to change in and out of, such as a short-sleeved top and soft trousers or joggers with an elastic waistband. Layers can be useful, as clinic temperatures may vary. Do not wear eye make-up as it can increase the risk of infection. We recommend choosing comfortable, supportive shoes with non-slip soles to help you move around safely.

Ensure to remove all jewellery before you arrive, including earrings, rings and necklaces, as these can interfere with surgical equipment.

What Medications Should Be Stopped Before Cataract Surgery?

Before cataract surgery, you should be aware of specific medications that may need to be stopped. This will depend on your individual medical history and the guidance of your surgeon. Be sure to mention any medications you are taking in your pre-op assessment appointments and your surgeon will make it clear if you need to adjust your medication before surgery and for how long. The following may be discussed:

1. Blood Thinners: Medicines like aspirin, which prevent blood clots, can increase the bleeding risk during and after surgery. Depending on certain factors, these medications may be adjusted or temporarily discontinued before cataract surgery.
2. Certain Herbal Supplements: Some herbal supplements, such as garlic, ginkgo biloba and ginseng, may have blood-thinning effects. Be sure to inform your surgeon about any herbal supplements so an informed decision can be made on their use.
3. Alpha Blockers: These can affect the muscles of the iris, leading to floppy iris syndrome during cataract surgery. Usage may sometimes need to be paused in advance.

Decisions about medication adjustments should always be made by your surgeon in collaboration with your GP or relevant specialists. Never stop taking any prescribed medication without professional guidance, as doing so may affect your overall health. Always disclose your full medical history to your consultant ahead of surgery.

What to Expect at Your Cataract Surgery Pre-Op Appointment

Ahead of your cataract surgery, a thorough pre-operative assessment ensures you’re fully prepared and safe to proceed. This visit is also an opportunity to ask any final questions.

What Happens During Your Cataract Pre-Op Assessment

During this appointment, your clinical team will carry out several important checks, including:

• A detailed eye examination, where the surgeon will measure the eye, visual acuity, examine the cornea, iris and lens, and evaluate pupil dilation.
• Biometry scans to ascertain corneal curvature and axial length and calculate your new lens strength
• A review of your medical history to check for underlying health conditions, allergies or medications you’re currently taking.
• Time to ask any final questions about the procedure.

Will You Need a General Health Check Before Surgery?

In most cases, a full physical exam isn’t required. However, if you have existing health conditions such as diabetes, high blood pressure or heart concerns, your GP or specialist may be consulted to confirm you’re fit for surgery.

What Blood Tests Are Done Before Cataract Surgery?

Routine blood tests are not typically needed before standard cataract surgery. If your consultant requests them, it will usually be to check for any health issues that could affect recovery.

Do You Need to Use Eye Drops Before Cataract Surgery?

If you’ve been prescribed eye drops to use before your cataract surgery, follow the instructions the medical team gave you to ensure your eyes are suitably prepared, free from infection and in the best possible condition for surgery.

Preparing Emotionally and Practically

It’s completely normal to feel nervous before eye surgery. Knowing how to prepare can help reduce anxiety and make the day run more smoothly.

• Bring a friend or family member with you for support and to take you home.
• Arrange time off work and avoid strenuous activity during early recovery.
• Write down any questions you’d like to ask on the day.

After surgery, follow your care team’s advice closely. You can also read our guide on tips for recovery after your cataract surgery.
