Astigmatism is a typical refractive mistake that happens when the cornea is irregularly formed, resulting in blurred or misshaped vision. While glasses or contact lenses can make up for the optical flaws caused by astigmatism, laser eye surgical procedure provides a more permanent service by reshaping the cornea to boost its concentrating ability.
Laser eye surgical procedure for astigmatism generally entails the use of two key strategies: LASIK (Laser-Assisted In Situ Keratomileusis) and also PRK (Photorefractive Keratectomy). Both procedures aim to remedy astigmatism by improving the cornea, yet they vary in the means the external layer of the cornea is accessed.
LASIK is the extra preferred selection among patients as a result of its faster healing time and less pain compared to PRK. In LASIK, a slim flap is produced on the cornea using either a microkeratome blade or a femtosecond laser. The flap is then raised, and an excimer laser is utilized to improve the underlying cornea. Ultimately, the flap is rearranged, functioning as an all-natural bandage.
On the various other hand, PRK includes the removal of the external layer of the cornea (epithelium) to access the underlying cells, which is then reshaped using an excimer laser. As PRK does not include the creation of a corneal flap, the healing period is much longer, and pain may be much more noticable in the days complying with the procedure. Nonetheless, PRK is often advised for individuals with slim corneas or other contraindications for LASIK.
Both LASIK as well as PRK have actually revealed exceptional success prices in dealing with astigmatism. The majority of individuals experience a significant enhancement in their visual skill, commonly attaining 20/20 vision or far better. Nonetheless, it is important to seek advice from an experienced eye doctor that can evaluate your private situation as well as establish one of the most appropriate treatment alternative for you.
Finally, laser eye surgical treatment provides a life-changing opportunity for people with astigmatism to accomplish clearer vision. Whether you select LASIK or PRK, the procedure can efficiently reshape the cornea as well as correct astigmatism, eventually enhancing your quality of life. If you are taking into consideration laser eye surgical treatment, consult with a certified eye doctor to review your alternatives and identify if you are an appropriate prospect.
