If you've had LASIK surgery in the past and are wondering if you can have it again after 20 years, the answer is yes. Most surgeons will not perform a second LASIK procedure unless 5 to 10 years have passed since the initial surgery. This is because LASIK permanently corrects the eye prescription you have at the time of surgery, and any underlying condition that progresses over time can cause changes in vision, making the original LASIK procedure less effective. The process for improving LASIK surgery after 10 years is almost identical to that of the initial surgery.
A mechanical microkeratome (blade) or a femtosecond laser is used to cut a flap in the cornea, and an excimer laser is used to remodel corneal tissue and improve the eye's ability to focus. In some cases, it may be necessary to repeat LASIK surgery after 10 years due to an underlying condition that changes vision over time, such as cataracts or presbyopia.If a second procedure has been deemed necessary, another tab will be created. This allows the laser to sculpt more tissue from under the LASIK flap, which increases the safety of the procedure and allows for a higher prescription LASIK. There is no evidence to suggest that someone who has undergone LASIK twice (initial procedure and an augmentation) is more likely than another person to need a second improvement.LASIK is generally considered a quick and safe surgery for treating vision problems with a high success rate.
After undergoing LASIK eye surgery, developing cataracts can affect the clarity of vision, so additional vision correction may be necessary.In conclusion, yes, you can have LASIK surgery twice. However, it's important to note that any underlying condition that progresses over time can cause changes in vision, making the original LASIK procedure less effective. If you're considering having LASIK again after 20 years, it's best to consult with your eye doctor first.
