Astigmatism is an usual refractive mistake that occurs when the cornea is irregularly formed, bring about obscured or distorted vision. While glasses or contact lenses can make up for the optical imperfections caused by astigmatism, laser eye surgery uses a more long-term option by reshaping the cornea to boost its focusing capability.
Laser eye surgery for astigmatism commonly involves the use of two primary strategies: LASIK (Laser-Assisted Sitting Keratomileusis) as well as PRK (Photorefractive Keratectomy). Both procedures intend to remedy astigmatism by improving the cornea, but they differ in the way the external layer of the cornea is accessed.
LASIK is the extra preferred choice among patients as a result of its faster recuperation time and less discomfort compared to PRK. In LASIK, a slim flap is produced on the cornea making use of either a microkeratome blade or a femtosecond laser. The flap is after that raised, and an excimer laser is made use of to reshape the underlying cornea. Ultimately, the flap is repositioned, acting as an all-natural bandage.
On the other hand, PRK entails the elimination of the outer layer of the cornea (epithelium) to access the underlying tissue, which is after that reshaped making use of an excimer laser. As PRK does not include the production of a corneal flap, the recuperation period is much longer, and also discomfort might be a lot more noticable in the days adhering to the procedure. Nonetheless, PRK is usually recommended for individuals with slim corneas or other contraindications for LASIK.
Both LASIK and PRK have actually revealed outstanding success rates in treating astigmatism. The majority of people experience a significant improvement in their aesthetic acuity, often achieving 20/20 vision or far better. Nonetheless, it is crucial to seek advice from a seasoned ophthalmologist that can evaluate your specific instance and identify the most suitable therapy alternative for you.
Finally, laser eye surgical treatment provides a life-changing opportunity for people with astigmatism to accomplish more clear vision. Whether you go with LASIK or PRK, the treatment can efficiently reshape the cornea and correct astigmatism, ultimately improving your lifestyle. If you are thinking about laser eye surgery, seek advice from a qualified eye cosmetic surgeon to discuss your alternatives and also determine if you are an appropriate candidate.
