We are frequently asked if it’s wise to have cataract surgery if you have Macular Degeneration.

Let’s start with some background.

  1. Cataracts and Age-related Macular Degeneration (AMD) are both leading causes of visual impairment in the elderly population.
  2. Cataracts develop when the normal clear lens gets cloudy with age. This is correctable with cataract surgery, which involves replacing the cloudy lens with a clear, artificial lens.
  3. While cataracts affect the front part of the eye, AMD causes damage to the retina, which is the inner back lining of the eye.

There have been concerns about cataract surgery causing progression of AMD. It has been thought that there was an inflammatory component to AMD and the normal inflammatory response after cataract surgery may lead to AMD progression.

But studies have looked at patients who underwent cataract surgery compared to patients who didn't have cataract surgery and the progression of AMD was not significantly different between the two groups. However, those patients with AMD who underwent cataract surgery had a significant improvement in vision.

AMD patients can further be characterized as having wet or dry AMD, and only those with wet AMD require treatment. Patients with wet AMD need injections to decrease the growth of new blood vessels and reduce fluid in the retina.

A 2015 study showed that after cataract surgery, there was an increase in fluid in the retina of patients with wet AMD. Therefore, in patients with wet AMD, we usually want the wet AMD to be stabilized before the patient has cataract surgery. Sometimes an injection may be given prior to cataract surgery to prevent any inflammatory changes that may be associated with cataract surgery.

The majority of the studies on the subject conclude that it is relatively safe to have cataract surgery even if you have AMD and in most cases there is a significant improvement in vision. Removing the cloudy lens also helps the ophthalmologist to better monitor the status of the AMD.  You will want to have a candid discussion with your eye doctor on the timing, benefits, and potential risks of cataract surgery with macular degeneration.
