Cataract surgery is one of the most commonly performed and safest surgical procedures worldwide, with millions of patients undergoing it every year. Despite its high success rate and low risk profile, the idea of eye surgery can be daunting for many patients. Understanding what to expect before, during, and after the procedure can alleviate anxiety and help you to feel more prepared.

In the weeks before your cataract surgery

Preparation is an essential part of ensuring a successful cataract surgery experience. Here’s what you can expect in the weeks leading up to the procedure.

1. Comprehensive Eye Examination

Your ophthalmologist will perform a thorough eye exam to:

• Confirm the presence and severity of cataracts.
• Rule out other conditions such as glaucoma or macular degeneration that might affect surgical outcomes.
• Measure your eye to determine the correct power and model of intraocular lens (IOL) to be implanted. This step can be very basic, or very elaborate, with the level of rigor differing quite significantly between ophthalmologists and clinics. More elaborate processes typically achieves better post-operative vision for patients.

2. Choosing the Best Intraocular Lens (IOL)

One critical decision is selecting the type of IOL to replace your natural lens. Options include:

• Monofocal Lenses: Provide clear vision at a single distance, either near or far.
• Multifocal Lenses: Can provide clear vision at both near and far vision, significantly reducing the need for glasses.
• Extended Depth of Focus (EDOF) Lenses: Can provide vision at both near and far vision, but with a higher image quality than multifocal lenses.
• Toric Lenses: Correct astigmatism in addition to providing clear vision.

Your lifestyle, vision goals, eye health, and budget will play a role in this decision, which you’ll discuss with your surgeon. It is important to remember that not every eye is suitable for all types of intraocular lens.

3. Pre-Operative Instructions

Your doctor will provide guidelines, such as:

• Medications: You may need to stop or adjust certain medications, such as diabetes medications, a few days before surgery. Blood thinning medications are usually not stopped for cataract surgery.

Fasting: You’ll be advised not to eat or drink for 4-6 hours before the procedure, so that you can have sedation by an anaesthetist.

Cataract surgery is typically an outpatient procedure, meaning you’ll go home the same day. Here’s what happens on the day of your surgery:

1. Arrival and Preparation

• You’ll arrive at the surgical centre, where staff will check you in and review your medical history.
• Your eye will be numbed with anaesthetic drops to ensure you don’t feel pain during the procedure.
• Your pupil will be dilated with eyedrops, to allow the surgeon to access the cataract. Your pupil will remain dilated for 12-24 hours.

2. The Surgical Procedure

The actual surgery usually takes about 15–25 minutes. The steps include:

• Intravenous sedation: The anaesthetist will give you medications to make you feel sleepy and reduce your memory of the procedure. Some surgeons operate with their patients feeling calm but awake, whereas I have all of my patients asleep.
• Creating an Incision: Your surgeon will make a tiny incision at the edge of the cornea. This incision is 2mm to 2.5mm wide.
• Removing the Cloudy Lens: Using ultrasound technology, the cataract is broken into small fragments and gently irrigated from the eye (a process called phacoemulsification).
• Implanting the Artificial Lens: The artificial IOL is inserted into the lens capsule, where it replaces the natural lens.

Thanks to advanced techniques and equipment, the procedure is minimally invasive, and the incision is self-sealing, which means that it closes without the need for stitches.

3. Recovery Room

After surgery, you’ll rest in a recovery area for about 45 minutes. The nursing staff will check your blood pressure, give you something to eat and drink, and explain your post-operative instructions to you and your carer. It’s essential to have someone drive you home you’re your vision will still be blurry from the procedure and you will still be feeling slightly sleepy from the sedation.

Short recovery time

The idea of eye surgery can be daunting, but fortunately the recovery is very easy! Most of Dr Andrew’s cataract patients achieve “20/20” vision within 1-2 days, and most return to normal activities 48 hours after their surgery.

1. Immediate Postoperative Effects

• Blurry Vision: It’s normal for your vision to be blurry or hazy immediately after surgery. Your eye needs time to adjust to the new lens.
• Mild Discomfort: You may experience itching, slight redness, or a foreign body sensation in the eye, but these symptoms usually subside within a few days.
• Light Sensitivity: Your eye may be sensitive to bright light for several weeks, so sunglasses are recommended when outdoors. The sunglasses aren’t medically essential, as your artificial lens implant blocks all incoming UV light, but the sunglasses will help you to feel comfortable when outside.

2. Follow-Up Appointments

Your first follow-up visit will be scheduled within one week of the surgery. Additional check-ups will occur over the next few weeks to monitor your healing and ensure you achieve the eyesight expected.

3. Using Eye Drops

Postoperative eye drops are a key part of recovery. These may include:

• Antibiotic Drops: To prevent infection.
• Anti-Inflammatory Drops: To reduce swelling and inflammation.

Your doctor will provide a specific schedule for using these drops.

4. Restrictions During Recovery

After your cataract surgery, you can do everything you normally do, with a few important exceptions:

• No driving for 24 hours.
• No eye make-up for 5 days.
• No eye rubbing for 2 weeks.
• No swimming or heavy weight lifting for 2 weeks.

While every patient’s recovery is unique, here’s a general timeline of what you can expect:

• Day 1: Vision may be blurry, although most patients report that their eyesight has already improved.
• Day 3-4: Vision becomes much clearer.
• 4-8 weeks: Vision stabilizes, and you’ll likely achieve your final visual outcome.

Cataract surgery is a transformative procedure that can restore vision and dramatically enhance your quality of life. By understanding what to expect at each stage of the process, you can approach the process with confidence and peace of mind.
