Can I have cataract surgery if I have age-related macular degeneration?

Age-related macular degeneration (AMD) and cataracts are both common conditions that affect older people. They are different diseases, but they can occur together, and having AMD does not mean you cannot have cataract surgery. The key question is not whether surgery is possible, but whether it is worthwhile, and how to manage expectations and aftercare carefully.

What is AMD and how does it affect vision?

AMD affects the macula, the central part of the retina at the back of the eye that is responsible for detailed, straight-ahead vision such as reading, recognising faces and seeing road signs. In AMD, this central area becomes damaged. There are two main types: dry AMD, which progresses slowly, and wet AMD, which can cause sudden changes due to abnormal blood vessel growth.

AMD does not affect the lens of the eye. Cataract, on the other hand, is a clouding of the lens at the front of the eye. Cataract surgery removes the cloudy lens and replaces it with a clear artificial lens. This improves the quality of light reaching the retina, but it cannot repair damage that has already occurred at the macula.

Can cataract surgery be done safely if you have AMD?

Yes, in most cases cataract surgery can be performed safely in people with AMD. The surgery itself is the same, and the presence of AMD does not make the operation technically impossible. However, the decision requires careful thought because the benefits may be more limited than in someone with a healthy macula.

For patients with dry AMD, cataract surgery can improve overall vision and contrast, but the central vision may still be limited by the macular damage. For patients with wet AMD, the eye should be stable and well treated before surgery. Active leakage or swelling at the macula usually needs to be controlled first, and we often coordinate with a retinal specialist.

Why vision after cataract surgery may not be perfect

Cataract surgery can give excellent results when the retina and macula are healthy. If the macula is already damaged by AMD, removing the cataract will improve clarity and contrast, but it will not restore the missing central detail. Some patients notice a big improvement in brightness and colour, even if the fine central vision remains reduced.

It is important to have a realistic discussion before surgery. The goal is to improve the quality of the vision you have, not to cure the AMD. For some patients, the improvement is very worthwhile; for others, the improvement is smaller and may not justify the small surgical risks.

Choosing the right lens

Lens choice is particularly important in patients with AMD. Multifocal, trifocal and extended-depth-of-focus lenses can split light into different focal points, which can reduce contrast. For patients with macular disease, who already have reduced contrast sensitivity, these premium lenses may not be the best choice. A monofocal lens, which gives a single sharp focal point, often provides better quality of vision for AMD patients.

Some patients with early AMD and good retinal health may still be suitable for certain premium lenses, but this decision must be made individually after a careful macular assessment.

What to expect before surgery

Before recommending cataract surgery in someone with AMD, we perform a detailed macular examination. This usually includes OCT imaging of the macula, sometimes a retinal scan to look for wet or active disease, and visual acuity testing. We also discuss what the surgery can and cannot achieve.

If the AMD is active, we may recommend treatment first or referral to a retinal specialist. If the AMD is dry and stable, we can proceed with surgery, but we will set realistic expectations about the likely outcome.

Aftercare for AMD patients

After cataract surgery, patients with AMD should have close follow-up. The eye is checked for inflammation, the pressure is monitored, and the macula is reviewed to make sure the AMD has not been aggravated. Occasionally, cataract surgery can cause a temporary change in the macula or unmask wet AMD that was previously subtle. Early detection and treatment of these changes is important.

Patients with AMD should continue any recommended treatments, such as dietary supplements or injections for wet AMD, and keep attending their retinal appointments after cataract surgery.

Benefits you may notice

Even when the macula is damaged, many AMD patients notice real benefits after cataract surgery. Colours may appear brighter, glare may be reduced, and the world may look sharper overall. These improvements can make daily activities easier, even if the central detail remains limited. Good lighting, magnifiers and low-vision aids can then make the best use of the improved vision.

Next steps

If you have AMD and cataracts, a consultant-led assessment is the best way to decide whether surgery is right for you. Bring your recent eye test results, a list of any AMD treatments or supplements, and your current glasses. We will examine the cataract and the macula, explain what surgery can realistically achieve, and recommend a lens choice and plan that suits your eyes.
