If you are thinking about lens replacement surgery, you may be wondering: does lens replacement hurt? It is a common concern, and it is completely understandable to feel nervous about having surgery on your eyes.
The good news is that lens replacement surgery is usually not painful during the procedure. Anaesthetic eye drops numb the surface of your eye, helping you stay comfortable. You may notice some pressure, movement or the sensation of liquid around your eye, but you should not expect to feel sharp pain.
I’m Dan Nguyen, a Consultant Eye Surgeon. I want you to feel informed and reassured before making any decisions about your vision. Let me explain what lens replacement surgery involves, what it feels like and what you can expect during recovery.
What is lens replacement surgery?
Lens replacement surgery, also known as refractive lens exchange (RLE), involves removing your eye’s natural lens and replacing it with an artificial lens implant.
As we get older, the natural lens inside the eye becomes less flexible. This can make it harder to focus on things up close, such as a book, a phone screen or small print. This age-related change is called presbyopia, and many people start to notice it in their 40s.
Lens replacement surgery can help improve vision and reduce your dependence on glasses or contact lenses. The type of artificial lens used will depend on your eyes, your prescription, your lifestyle and what you would like to achieve.
Not everyone is suitable for this procedure, so a thorough eye assessment is important before deciding whether it is the right option for you.
What happens during lens replacement surgery?
Understanding what happens during surgery can help you feel more prepared and less anxious.
Before the procedure
Before surgery, I will assess your eyes and take measurements to help determine the most suitable lens implant. We will also discuss your vision, your daily activities and your expectations.
You will have the opportunity to ask questions and understand what the procedure involves before making a decision.
During the procedure
Your eye is numbed with anaesthetic drops to help prevent pain. You will usually be awake during surgery, but you should not feel sharp pain.
I make a very small opening in the eye and carefully remove the natural lens. An artificial lens is then placed inside the eye. The procedure usually takes around 15 to 30 minutes per eye, although the exact time can vary.
You may notice lights, movement or a feeling of pressure while the procedure is taking place. These sensations are not the same as pain, and the team will guide you through the process.
Lens replacement surgery is generally performed as a day procedure, meaning you can usually go home the same day. You will need someone to take you home, as you should not drive immediately after surgery.
Is lens replacement surgery the same as cataract surgery?
Lens replacement surgery and cataract surgery use a similar technique: both involve removing the natural lens and replacing it with an artificial lens implant.
The main difference is why the surgery is performed.
Cataract surgery treats a natural lens that has become cloudy and is affecting your vision. Lens replacement surgery is usually performed when the natural lens is still clear but has lost some of its ability to focus, often because of age-related changes.
Both procedures require careful assessment and planning. You can learn more about premium cataract surgery if you would like to understand how cataract treatment works.
Does lens replacement surgery hurt afterwards?
Although lens replacement surgery is usually comfortable during the procedure, your eye may feel different afterwards.
Some people experience mild grittiness, watering, sensitivity to light or a feeling similar to having an eyelash in the eye. Mild discomfort can occur during the first few days as the eye begins to heal.
Your recovery may be different from someone else’s. Follow the aftercare instructions you receive, including how and when to use your prescribed eye drops. Avoid rubbing your eyes and follow the advice you are given about washing, exercise and other activities.
If you experience severe or increasing pain, a sudden change in vision, or significant redness, contact your eye care team urgently. These symptoms should not be dismissed as normal recovery.
How long does it take to recover from lens replacement surgery?
Many people notice an improvement in their vision within the first few days, but your eyes need time to heal. Your vision may be blurry at first and can take longer to settle fully.
You may be able to return to some everyday activities relatively quickly, but this depends on how your eyes recover and the instructions provided by your surgeon. Do not assume that you can drive or return to every activity straight away.
You will also need to attend any recommended follow-up appointments so your recovery and vision can be checked.
Is lens replacement surgery safe?
Lens replacement surgery is an established procedure, but, like all surgery, it carries risks. These can include inflammation, infection, changes in eye pressure, retinal complications and problems with the lens implant.
The likelihood of complications varies between individuals. Your eye health, medical history and the type of treatment being considered all matter.
During an assessment, I can explain the potential benefits and risks in the context of your eyes. This helps you make an informed decision about whether lens replacement surgery is appropriate for you.
Could lens replacement surgery be right for me?
If you are finding reading difficult, relying more on glasses or contacts, or looking for a longer-term way to address age-related changes in your vision, lens replacement may be worth exploring.
However, it is not suitable for everyone. The best way to find out is to have your eyes assessed and discuss your goals with an eye surgeon. You can also explore our lens replacement treatment page to learn more about the procedure.
