Laser-assisted in-situ keratomileusis (LASIK) is refractive eye surgery that corrects unusual vision disorders, such as nearsightedness, farsightedness, and astigmatism. It is estimated that between 20 and 25 million LASIK procedures have been performed in the United States. since it was approved through the United States Food and Drug Administration (FDA) in 1999, for the purpose of cutting or eliminating a person’s dependence on glasses or touch lenses. [1] Joffe SN. The 25th anniversary of laser vision correction in the United States. Clinical Ophthalmology. 2021; 15 : 1163-1172. .
Despite its wide acceptance and high success rates, it is vital not to forget that LASIK, like any surgical procedure, carries risks. Continue reading to learn more about LASIK, adding what it is, who deserves the procedure, and LASIK good luck rates.
LASIK is a form of laser corrective eye surgery used for vision in people with refractive errors, such as nearsightedness (nearsightedness), farsightedness (farsightedness), and astigmatism. These refractive errors are usually the result of poor focusing of the eye due to the shape of the cornea, lens, or the eye itself.
During the LASIK procedure, which typically takes less than 10 minutes, a numbing drop is placed in the eye. A thin flap of tissue is then created in the cornea with a specialized tool or laser. Once this flap is lifted, the computer-guided laser is used to reshape the cornea to the correct size in case of refractive error or focal power. The flap is then returned to its original position and allowed to heal.
The most productive way to know if you are a smart candidate for LASIK surgery is to see your ophthalmologist for an evaluation. “Generally speaking, LASIK applicants must be 18 years of age or older and must not be pregnant or breastfeeding. ” says John F. Doane, M. D. , a board-certified ophthalmologist and LASIK surgeon in Kansas City, Kansas. According to Dr. Doane, some eye situations that may disqualify a LASIK candidate include:
The cornea, which is the clear, window-shaped tissue in the front of the eye, also wants to be thick and healthy for LASIK to be performed safely, adds Jason N. Edmonds, M. D. , board-certified ophthalmologist, cornea specialist. and spouse. of Milwaukee Eye Care.
Realistic expectations are also important. People want to understand that LASIK does not guarantee the best vision. And although individual effects vary, your ophthalmologist can know exactly what to expect before, during and after the procedure.
“LASIK is an effective procedure with very high satisfaction rates among those who have undergone surgery,” says Dr. Edmonds.
In general, studies show that LASIK patients are satisfied with the results. According to a 2016 study published in the Journal of Cataract
Another study reported an overall patient satisfaction of about 2. 64 on a scale of 0 to 3, where a score of 3 means that the patient was absolutely satisfied. This study also found that more than 98. 5% of patients reported that the number one goal of surgery had been achieved. and that they would make the same resolution if they had to do it again. [3] Bamashmus MA, Hubaish K, Alawad M, et al. Functional end results and patient satisfaction after laser in-situ keratomileusis for myopia correction and myopic astigmatism. Middle East African Journal of Ophthalmology. 2015; 22(1):108-114. .
Some studies suggest that certain populations may have better results after LASIK. For example, studies indicate that younger people have experienced faster and more complete healing than older people. Male patients also reported better results. However, further studies are warranted. 4]Gomel N, Negari S, Frucht-Pery J, et al. Predictive points of efficacy and protection of myopia refractive surgery. PLOS A. 2018; 13(12):e0208608. .
LASIK is sometimes thought of as a procedure with the highest satisfaction rates. However, like any surgical procedure, LASIK comes with side effects and potential risks, whether short-term or long-term, Dr. Edmonds says.
After the procedure, it is usually mild discomfort or pain. You may also experience burning, itching, and sensitivity to light immediately after the procedure. These side effects go away within a few days. Patients suffer from transient dry eye for 3 to 4 months, but this can be resolved with synthetic tears, Dr. Doane adds.
Long-term threats can occur, although rare. A very small number of people may experience vision loss or develop symptoms such as glare, halos, or double vision, which can affect vision in low-light situations, such as at night. Another possible threat is the progression of dry eye syndrome. , a condition that causes discomfort and visual impairment, which can be permanent in some cases. In addition, other people may still need glasses or touch lenses after a LASIK procedure.
“Many long-term threats related to surgery can be avoided after a thorough consultation with an experienced surgeon,” says Dr. Edmonds. “Not everyone is a smart candidate for LASIK. Proper evaluation before surgery can identify patients who are at higher risk for complications.
However, it is vital to note that severe headaches are rare and most patients are satisfied with the results. Your surgeon will discuss potential dangers and headaches with you in detail before the procedure to ensure you have a clear understanding of potential headaches. results and can make an informed decision about LASIK.
If you think you’re a smart candidate for LASIK, make an appointment with your ophthalmologist. They will evaluate your individual situation and help you if the procedure is right for you.
