If your world is getting a little cloudy, it may not be the weather. You could be developing cataracts, which means the lens in one of your eyes – or both eyes – has becomes partly or completely cloudy.

The lens plays a vital role in helping us see clearly. When you look at something, light passes through the clear cover or cornea, which bends it and sends it inside the eye to the lens. The lens then focuses the light onto the retina – which acts like the film in a camera – inside the eye. The retina then sends the information to the brain

At some point in many of us, our lenses will start to change and go from clear to cloudy which will prevent the retina from receiving a sharp image – and the image you see will be blurry. If this has happened to you, you may be wondering if you’re developing cataracts – and have questions about what to do. This Q&A can help you find answers to some of the most commonly-asked questions about this eye condition:

How will I know if I have cataracts?

If you’re over 60 and your vision has started getting cloudy or fuzzy and colors seem faded, you may have cataracts. Some people begin to experience these symptoms as early as in their 40s or 50s. Other changes in vision to watch for include reduced night vision, halos around lights and double vision. Getting cataracts is part of the normal aging process – although it can happen at any time in your life – and also a common condition if you have diabetes, an eye injury, or use steroid eye drops or tablets. If you smoke, drink alcohol and have a poor diet, you’re also at risk for cataracts. If you notice any changes in your vision, or suspect you have cataracts, schedule an appointment with your eye care professional.

What tests will my eye care professional give me?

In addition to giving you a comprehensive eye exam, your eye doctor (either an optometrist or ophthalmologist) will:

Will I need eye surgery?

Some cataracts stay small and may not need to be removed, but if they start to interfere with your everyday activities, then you may want to consider surgery. This typically is an outpatient operation, during which your cataract surgeon (also known as a refractive surgeon) will remove the cloudy lens and replace it with an artificial intraocular lens (IOL) implant.  Conventional cataract surgery is extremely effective and there is a new option of laser cataract surgery that may be a good option to discuss with your surgeon. Learn more about what to expect during cataract surgery.

What IOL lens options will I have?

There are several types of IOL technology available, including standard or monofocal lenses, which can correct vision at one field of distance (near, far or intermediate). The latest multifocal or accommodative intraocular lenses can help you see both near and far objects with a reduced or even complete reduction in the need for glasses. Toric intraocular lenses can help correct astigmatism and distance vision, but you may need glasses for reading. Just like LASIK, there is an IOL monovision option, which uses two different lenses to correct near vision in one eye and distance vision in the other. Discussion your vision goals with your eye surgeon and together you can determine the best IOL technology to fit your vision needs.

What can I do to delay getting cataracts?

There are several simple lifestyle choices you can make that might help you delay getting cataracts: Wear sunglasses with UV protection and a hat. Don’t smoke. Eat a healthy diet that includes lots of fruit and vegetables as they are high in protective antioxidants such as Vitamin C, A and E. Plus, it bears repeating, regular visits to your eye care professional are important to your vision and overall health.

Does it matter that I’ve had LASIK eye surgery in the past?

Generally speaking, no.  In fact, cataract surgery can be performed after most vision correction procedures, including LASIK,  PRK, SMILE, and ICL.

LASIK and other laser vision correction techniques are performed on the cornea – which is the front surface of the eye.  Cataract surgery replaces the lens of the eye which sits behind the pupil.  Both the cornea and the lens help your eye focus, but they are different structures.

That said, it is important to let your cataract surgeon know you have had previous eye surgery.  It is also helpful if you can give your surgeon copies of your eye exams that were performed prior to your LASIK or other laser vision correction procedure.

Cataract surgery can be successfully performed without your pre-LASIK records. But, if you are interested in the latest vision-correcting intraocular lens (IOL) technologies available to cataract patients, those records can offer your surgeon information to help determine the optimal focusing power of the IOL for your cataract surgery.
