What to Expect When It’s Time for Cataract Surgery: An Optometrist’s Guide

As an optometrist, I’ve had the privilege of helping many patients navigate the journey of cataract surgery. This procedure, though common and typically very successful, can understandably be a source of anxiety for many. In this article, I aim to demystify the process and provide you with a comprehensive understanding of what to expect before, during, and after cataract surgery.

Understanding Cataracts

First, it’s important to understand what cataracts are. Cataracts occur when the lens of your eye becomes cloudy, leading to blurry vision, difficulty with night vision, and seeing halos around lights. They are most commonly associated with aging, but can also result from diabetes, smoking, prolonged exposure to ultraviolet light, and other factors.

Pre-Surgery Preparation

1. Comprehensive Eye Examination

Before your surgery, you’ll undergo a thorough eye examination. This includes various tests to measure the size and shape of your eyes, which helps in selecting the appropriate intraocular lens (IOL). Your optometrist will also evaluate your overall eye health to ensure there are no other conditions that might affect the surgery.

2. Discussing IOL Options

There are different types of IOLs available, each with its own benefits. Monofocal lenses provide clear vision at one distance, while multifocal lenses can correct vision at multiple distances, potentially reducing the need for glasses. Your lifestyle, preferences, and eye health will guide the decision on which lens is best for you.

3. Pre-Surgical Instructions

You’ll receive specific instructions on how to prepare for surgery. This typically includes discontinuing certain medications and avoiding food and drink for a specified period before the procedure. You may also be prescribed eye drops to start using before the surgery.

The Day of Surgery

1. Arrival at the Surgical Center

On the day of your surgery, you’ll arrive at the surgical center, where you’ll be greeted by the medical team. They’ll explain the process and address any last-minute questions or concerns you may have.

2. Anesthesia and Preparation

Cataract surgery is usually performed under local anesthesia, meaning you’ll be awake but your eye will be numbed. In some cases, a mild sedative is given to help you relax. Your eye will be dilated with special drops, and the area around your eye will be cleaned and prepped.

3. The Procedure

The actual cataract surgery typically takes about 15-30 minutes. Here’s a step-by-step outline of what happens during the procedure:

  • Incision: A tiny incision is made in the cornea.
  • Lens Removal: Using a process called phacoemulsification, ultrasound waves are used to break up the cloudy lens, which is then gently suctioned out.
  • IOL Insertion: The new IOL is inserted into the empty lens capsule.
  • Closure: The incision is usually so small that it heals without the need for stitches.

4. Post-Surgery Recovery

After the procedure, you’ll rest in a recovery area for a short while. Your eye will be covered with a protective shield, and you’ll receive instructions on how to care for your eye.

Post-Surgery Care

1. Immediate Aftercare

In the first few hours after surgery, you might experience mild discomfort, itching, or a feeling that there’s something in your eye. These sensations are normal and should subside within a day or two. It’s crucial not to rub your eye.

2. Medications and Follow-Up

You’ll be prescribed eye drops to prevent infection and reduce inflammation. It’s important to use these as directed. Your first follow-up appointment will usually be the day after surgery, with additional visits scheduled over the following weeks to monitor your healing.

3. Activity Restrictions

During the initial recovery period, you’ll need to avoid strenuous activities, heavy lifting, and bending over, as these can increase pressure in your eye. Your optometrist will provide specific guidelines on when you can resume normal activities.

4. Vision Improvement

Many patients notice an improvement in their vision within a few days, although it can take a few weeks for your vision to stabilize fully. Your eye may be sensitive to light, and colors may appear brighter. Some patients require glasses for certain activities, while others may not need them at all.

Long-Term Considerations

1. Adjusting to Your New Vision

Adjusting to your new vision can take some time, especially if you’ve chosen a multifocal IOL. Your brain needs to adapt to the new visual input, which can take several weeks to months. Be patient with this process.

2. Secondary Cataracts

In some cases, the lens capsule that holds the IOL can become cloudy over time, leading to what is known as a secondary cataract. This can be treated with a quick and painless laser procedure called a YAG laser capsulotomy.

3. Regular Eye Examinations

Even after a successful cataract surgery, it’s important to continue regular eye examinations. Your optometrist will monitor your eye health and ensure that any other conditions, such as glaucoma or macular degeneration, are detected and managed early.


Cataract surgery is a highly effective procedure that can significantly improve your quality of life by restoring clear vision. By understanding what to expect before, during, and after surgery, you can approach the process with confidence and peace of mind. Remember, your optometrist and surgical team are there to support you every step of the way. If you have any concerns or questions, don’t hesitate to reach out. Your vision is our priority, and we’re committed to helping you achieve the best possible outcome.
