Laser Assisted in Situ Keratomileusis, or “LASIK” is a surgical procedure that reshapes the cornea of the eye to provide clearer vision without corrective lenses. Millions of people have undergone this type of eye surgery that allows them to see clearly without glasses. Today, its become a realistic option for people of all ages, even seniors, are considering this procedure that allows them to do away with cumbersome eyeglasses and contact lenses, improves their ability to enjoy activities and enhances their self-confidence.
Understanding LASIK Eye Surgery
The LASIK procedure uses specialized equipment and techniques to re-shape the cornea of the eye to provide clearer vision. A normal cornea is very rounded, which allows light to refract images onto the retina at the back of the eye, creating a precise image. However, when the cornea is irregularly shaped, these images may be distorted, producing an image that is blurred and which may result in eye fatigue and frequent headaches.
Eyeglasses provide an external method for correcting the light refraction to provide clearer vision. Similarly, contact lenses re-shape the cornea to make images clearer. LASIK does the same thing by directly re-shaping the corneal tissues, so they can provide better vision.
The procedure cuts a small flap on the cornea with a special instrument or laser. The tissue is then gently reshaped, and the flap replaced on the surface of the eye. Eye drops anesthetize the surface of the eye so there is no discomfort. Healing from the procedure only takes a day or two.
Concerns about LASIK Surgery in Older Adults
Adults over the age of 60 pose a few additional concerns for LASIK eye surgery. Older individuals may have medical conditions, such as diabetes, that may affect the health of the eyes. In addition, seniors may have existing eye disease such as macular degeneration or glaucoma that prevents them from having the surgery. Medications can also have an effect on the eyes. In particular, an anti-arrhythmia drug called amiodarone can cause significant side effects after the surgery. Other drugs may also produce troublesome effects. Your doctor can provide more information about medications and LASIK eye surgery.
Who Should Not Undergo LASIK Vision Correction
Not everyone will be a good candidate for LASIK eye surgery. Individuals with autoimmune disorders or immunodeficiency problems should not get LASIK surgery. If your eye surgeon says your eyes are beginning to have clouding of the lens, a condition called cataract, you should probably discuss a different option for vision correction.
If you have an eye infection, you should not have the surgery. If you have dry eye syndrome, LASIK eye surgery may make the problem worse. Inform your eye surgeon about any medications you are taking. Some medications, like steroids, can have an effect on the condition of your eyes.
Monovision Option for Seniors with Presbyopia
Older adults with presbyopia, a problem with seeing images up close, may be able to benefit from LASIK monovision surgery. In this procedure, one eye is corrected for distance viewing, while the other is corrected for close viewing. In this way, the individual can use one eye for far images and the other for close work. Most people adapt quite easily to switching from one eye to another for changes in viewing. However, you should speak to your surgeon to determine if this method is would be right for you.
LASIK Surgery and Cataracts
LASIK surgery only corrects refractive errors caused by irregular shaping of the cornea. It does not remove cataracts that may develop due to aging. However, your eye surgeon can implant premium intraocular lenses that correct vision when you have your surgery to remove the cataracts. These lenses are not generally included under insurance for cataract surgery, so you can expect to incur additional costs with this method.
If you are considering LASIK eye surgery to help you see without glasses or contact lenses, talk to your eye surgeon about your options for surgery, your general health and the medications you take. Although not everyone can undergo LASIK, many seniors have found that the procedure has allowed them more freedom to engage in recreational activities and has provided a boost in self-confidence about their appearance.
