However, your candidacy depends on several factors, including the amount of tissue removed during the first procedure. During a consultation at Kirk Eye Center, inform our team about any eye conditions that may have developed since your first laser surgery.
Cataracts, glaucoma, and even chronic dry eye may have an impact on your results. For example, your first surgeon may not have removed enough corneal tissue to correctly address your refractive error. Another trained eye specialist in River Forest or Gurnee, IL can inform you about your options and whether a second operation will be more successful. In more common cases, however, your vision may change over time due to natural aging. This is called presbyopia, and it occurs when your eye lens becomes less flexible over time.
You may not be able to focus on nearby objects as well as in the past. While LASIK is considered safe and effective by most medical professionals, it is still important for patients to be aware of the potential complications and risks involved. But since your eyes change over time, you may develop new refractive errors after the surgery. Regardless of whether you need additional LASIK or anticipate LASIK enhancement, you should follow all the best recovery practices to improve the likelihood of successful recovery after the first and second surgery.
LASIK is considered a safe procedure. As with any surgical procedure, however, there are risks involved, and a small percentage of people can experience negative side effects or complications, such as visual disturbances halos, glares, starbursts, poor night vision, and difficulties discerning contrast , dry eyes, and possible vision loss. Most of these negative side effects clear up within a few weeks to months of undergoing a LASIK procedure.
Of course, when you undergo more than one LASIK surgery, the risks can increase and the rate of complication can therefore increase as well.
The main factor in determining candidacy for LASIK enhancement and secondary surgeries is the size and thickness of the cornea, the American Academy of Ophthalmology explains. LASIK uses specialized lasers to create a thin flap in the corneal tissue to reach the stroma, or internal part of the cornea, to ablate and change its shape in order to correct refractive errors.
The shape of your cornea is what can cause you to be nearsighted, farsighted, or suffer from astigmatism. LASIK can correct all of these refractive errors that make it difficult to focus and see clearly. Enhancement surgeries will need to harvest more corneal tissue, and at some point, you will not have enough. Your ophthalmologist will measure the thickness of your cornea to determine your eligibility for LASIK initially and in the case of any enhancement surgeries.
There are still laser surgery procedures like PRK that can be performed as enhancement procedures if your cornea is too thin, however. Be sure and talk to your doctor to determine what is going to work best. The Review of Ophthalmology warns that the risk for epithelial ingrowth and corneal ectasia are possible complications of a LASIK enhancement that involves lifting the corneal flap an additional time. Epithelial ingrowth is a condition where extra cells collect under the flap and can lead to visual disturbances and discomfort.
It may also need to be retreated with additional surgery. The Review of Ophthalmology publishes that surgeons often consider going with a PRK procedure as an alternative to LASIK when doing an enhancement in order to minimize the risk for epithelial ingrowth.
Corneal ectasia is a rare condition that can occur after LASIK, causing bulging of the cornea, often because the tissue was too thin. Accurate corneal tissue measurements are imperative to determine the safety and efficacy of a LASIK enhancement to minimize potential complications. In the case of significant astigmatism, myopia nearsightedness , or hyperopia farsightedness , a LASIK surgery may undercorrect the refractive error.
This means that not enough of the corneal tissue is removed and reshaped, and vision is not completely corrected. This can result in the desire for an enhancement surgery to remove more tissue and complete the correction for improved vision. As you get older, your eyes change. The American Refractive Surgery Council reports that your vision changes at a rate of about 1 percent each year, so after about 10 years post LASIK, your vision may be 10 percent different.
The Federal Trade Commission publishes that you are more likely to need an enhancement LASIK surgery if you had a significant refractive error myopia, astigmatism, hyperopia initially. It is also possible to develop a secondary condition later in life that will require another laser eye surgery to correct. For example, most people will suffer from "aging eyes" or presbyopia around age 40 or so, the National Eye Institute explains.
LASIK is considered a long-lasting procedure that millions have undergone and loved. LASIK involves reshaping the cornea and fixing refractive errors.
Many vision changes due to age occur as early as Although you may not realize it, you could have cataracts or glaucoma! If a second procedure has been deemed necessary, another flap will be created. Instead, their eyes are merely changing with age. As cataracts develop, patients will slowly lose their vision, as well as their clarity.
With cataracts, the only true solution is to have cataract surgery. The lens is a different part of the eye. Another way that the eyes change with age is the development of presbyopia. Presbyopia occurs as the eyes lose their natural ability to focus. This is why many people who are forty or older use reading glasses to see more clearly.
Presbyopia causes the lens of the eye to thicken and lose flexibility. Schedule an appointment with Georgia Eye Associates in Buckhead and get answers! Poland, M.
