It’s not too late to remove your cataracts surgically. And it’s not too early to reduce your risk of developing them.
Cataracts are simply a thickening and clouding of our eyes’ lenses.
In the case of cataract surgery, it happily still is. The oldest known cataract-surgery patient was 109 at the time of the operation and recovered wonderfully. Absent any major health complications, which after all could affect patients of any age, successful cataract surgery is an option for anyone.
It’s a simple fact of life, though, that as we age, underlying conditions can become more numerous and complex. In the case of cataract surgery, the underlying conditions that most directly affect a patient’s chances for success include the following:
Advanced cataracts
At a certain point late in their development, cataracts may not be surgically treatable without a high risk of additional complications. For instance, highly mature cataracts can become so thick that they affect not just the lens but the membrane, or capsule, enclosing it. This capsule is left intact during standard cataract surgery, but when it is stretched by an extremely thickened lens, it may complicate surgery, and worse yet might not hold the new lens properly in position.
Medical conditions
These include diabetes, glaucoma, uveitis, and macular degeneration. None of these conditions necessarily eliminates cataract surgery from consideration, but they do affect the nature of the procedure and the patient’s chances of full recovery. A frank conversation with your ophthalmologist will help each of you understand how an underlying condition affects your candidacy for surgery.
Previous surgeries and injuries. Surgeries and injuries affecting the lens and the suspensory ligaments that connect it to the rest of the eye may affect a patient’s chances for successful cataract surgery.
Genetic factors
Certain genetic conditions, including Marfan syndrome, greatly complicate cataract surgery and may preclude it altogether.
Nor is it as important as it once was to wait until cataracts have fully developed before having surgery. The old conventional wisdom held that cataracts needed to mature before surgery could be performed with minimal risk and the best chance for success.
That’s no longer true: as soon as cataracts are diagnosed, patients can start to work with their ophthalmologists on a schedule for the inevitable surgery. Not all cataracts are even noticeable, and early in their development, they may be manageable with little impact on a patient’s life. During these early stages, ophthalmologists and patients have an opportunity to plan an effective strategy that delivers the right treatment at the right time.
In the meantime, a host of lifestyle-related factors can contribute to cataracts. Minding those can help prevent cataracts from forming and may slow their development. These include
- Environmental factors. Prolonged exposure to direct sunlight can exacerbate a patient’s natural predisposition to cataracts. While you’re protecting your skin from UV damage, consider whether you’re putting your eyes at risk as well.
- Personal choices. Poor diet and lack of exercise can lead to diabetes and thence to glaucoma, two of the most significant underlying medical conditions that encourage the development of cataracts. Smoking appears to significantly increase the risk of cataracts, and alcohol consumption is associated with a slightly increased risk.
With proper attention to your habits and environment and frank discussions with your ophthalmologist, there’s less reason than ever to fear the development of cataracts or worry about what to do if they ever start to form.
