Myopia is a vision disorder that affects a large proportion of the world’s population. It manifests itself as blurred vision at a distance, often requiring those affected to wear glasses or contact lenses. But did you know that a surgical solution exists to correct myopia? In this article, we will explore laser eye surgery to treat myopia.
Understanding myopia
Myopia, commonly called “short eye”, occurs when the eye is too long in relation to its focusing power, or when the cornea is too curved. Result: images are formed in front of the retina rather than directly on it. This causes blurred vision of distant objects.
Refractive surgery: a glimmer of hope for myopes
Refractive surgery encompasses a range of procedures aimed at changing the shape of the cornea. Its main purpose is to allow images to form on the retina, thereby improving vision.
Main techniques
LASIK
LASIK, or “Laser-Assisted In Situ Keratomileusis,” is one of the most popular methods. It involves creating a thin flap in the cornea with a laser or a microkeratome. Once the flap is raised, the laser reshapes the underlying cornea before replacing the flap. Benefits include rapid recovery and reduced post-operative pain. However, it may not be suitable for those with particularly thin corneas.
PRK
Photorefractive Keratectomy (PRK) is another, older technique that involves removing the outer layer of the cornea (the epithelium) before reshaping it with a laser. Although it has a longer healing time than LASIK, PRK may be better suited for people with thin corneas.
Preparing for laser eye surgery
Before the operation, a pre-operative consultation is necessary. The doctor will assess the health of your eyes, measure the thickness of your cornea, and discuss the best options for you. It is essential to avoid wearing contact lenses at least one week before the evaluation to obtain accurate measurements.
After the operation
After surgery, a burning or foreign body sensation is common, and slight sensitivity to light may be felt. Post-operative follow-up is essential to ensure that everything goes well. Visual improvements may be immediate, but vision may continue to improve for several days.
Risks and complications during laser eye surgery
As with any surgery, risks exist. Some of the most common are dry eyes, reduced night vision, or the formation of holograms around lights. Rare but more serious complications, such as infections, can also occur. It is essential to carefully follow post-operative instructions to minimize these risks.
Testimonials
Marie, 34 years old, testifies: “After my LASIK, I was able to see clearly without glasses for the first time since I was a child. It’s liberating! ».
Paul, 29, who opted for PRK, shares: “The recovery took longer than I expected, but the result was worth it. ».
Alternatives to laser surgery
For those who are unwilling or unable to undergo surgery, glasses or contact lenses remain viable options. Other surgical procedures, such as the placement of intraocular implants, may also be considered.
In conclusion
Laser eye surgery offers a promising solution for people with myopia. However, a thorough assessment by a specialist is essential to determine the best option for each individual. If you are considering this surgery, take the time to inform yourself, weigh the pros and cons, and consult an experienced ophthalmologist.
