Is it possible to have vision correction surgery again after LASIK and LASEK?
Dec 01, 2024
Interest in vision correction surgery such as LASIK and LASEK is increasing among test takers who have completed the SAT.
Eye correction surgery is one of the surgeries performed by many people with interest as its safety has been verified to some extent for 30 years since its introduction in 1991. Early surgery people are increasingly considering a second vision correction surgery due to their decreased vision over time, and it is important to find a suitable reoperation method for each individual for safe and satisfying surgery.
Generally well-known vision correction surgery includes LASIK, LASEK, SMILE LASIK, and guided lens insertion. LASIK and LASEK are surgery to correct refractive abnormalities such as myopia, astigmatism, and primitiveness by irradiating a laser on the cornea, and if the levels of myopia and astigmatism are higher than the corneal thickness, it can be corrected by guided lens insertion. Although the success rate is relatively high, vision may gradually deteriorate again after as early as 6 to 7 years or more than 10 years due to natural aging or progression of myopia.
Since LASIK and LASEK are surgery to cut the cornea, the cut cornea must remain in that state, but if the cornea grows back and thickens, vision can change. If you have a lot of corneal cutting due to the large amount of myopia, the cornea can regenerate by the amount of cutting, which can speed up the rate of vision loss. In addition, in the case of patients with high myopia, there is a possibility that myopia may progress due to prolonged axillary field.
Even if you have already undergone vision correction surgery, you can receive LASIK or LASEK again depending on the amount of remaining corneas, eye condition, and age. However, patients who do not have enough residual corneas or have cut a lot of corneas due to high myopia may consider guide lens insertion. Guide lens insertion is a method of inserting a special lens in front of the lens while preserving the cornea as it is, and it is suitable for patients who have difficulty in laser-cutting LASIK or LASEK surgery due to thin corneas. In addition, because the cornea is not touched, myopia regression is relatively small.
Among patients who underwent LASIK and LASEK surgery, guide lens insertion is possible ▲ vision loss due to aging ▲ vision loss due to myopia ▲ vision loss due to excellent corneal regeneration ability, resulting in vision regression as before surgery. However, since guide lens insertion is a surgery to insert a lens into the eye, it is necessary to secure enough space in the eye, so a detailed examination should be conducted and decided in advance. In addition, if you are over 45 years old or close to your 50s, you may need to use a magnifying glass even if you have surgery due to advanced presbyopia, so various factors should be considered comprehensively.
Many patients are curious about the possibility of replacing the lens or reoperation after the guide lens insertion. In general, if the lens is removed after the guide lens insertion, it can return to its original eye state. The guide lens is located in front of the lens and behind the iris, and although rare, it affects the lens, resulting in cataracts or corneal endothelial cells are damaged due to affecting the cornea. In this case, reoperation to replace or remove the lens may be necessary.
Hwang Kyu-yeon, a specialist at the LASIK Center at Kim Ophthalmology Hospital, said, "As Korea usually operates between the ages of 19 and 20, compared to other countries where surgery is performed between the ages of 24 and 25, growth is more advanced and shortsightedness is sometimes performed." "When considering reoperation, high satisfaction can be expected only when the cause of vision loss is identified through various thorough examinations and a method suitable for reoperation is sought according to age, myopia, and residual corneal volume."," he stressed.
