Astigmatism is a typical refractive mistake that happens when the cornea is off-and-on formed, leading to blurred or misshaped vision. While glasses or call lenses can make up for the optical flaws caused by astigmatism, laser eye surgery supplies a much more irreversible service by reshaping the cornea to enhance its concentrating ability.
Laser eye surgical procedure for astigmatism commonly involves using two primary methods: LASIK (Laser-Assisted In Situ Keratomileusis) and also PRK (Photorefractive Keratectomy). Both procedures intend to fix astigmatism by reshaping the cornea, but they differ in the way the outer layer of the cornea is accessed.
LASIK is the more preferred option among patients because of its faster recovery time and less discomfort compared to PRK. In LASIK, a slim flap is created on the cornea making use of either a microkeratome blade or a femtosecond laser. The flap is then lifted, as well as an excimer laser is utilized to reshape the underlying cornea. Ultimately, the flap is rearranged, functioning as a natural bandage.
On the other hand, PRK involves the removal 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 involve the development of a corneal flap, the healing duration is much longer, and also pain might be a lot more pronounced in the days complying with the procedure. However, PRK is often advised for people with slim corneas or various other contraindications for LASIK.
Both LASIK and PRK have shown superb success rates in dealing with astigmatism. The majority of clients experience a significant improvement in their aesthetic skill, commonly attaining 20/20 vision or much better. Nevertheless, it is critical to consult with a skilled eye doctor that can evaluate your specific situation and determine the most appropriate therapy alternative for you.
In conclusion, laser eye surgery offers a life-altering possibility for individuals with astigmatism to accomplish clearer vision. Whether you choose LASIK or PRK, the procedure can successfully reshape the cornea and also proper astigmatism, eventually boosting your quality of life. If you are considering laser eye surgical treatment, talk to a qualified eye specialist to review your choices as well as establish if you are an ideal candidate.
