Astigmatism is a common refractive error that takes place when the cornea is irregularly shaped, leading to blurred or misshaped vision. While glasses or contact lenses can make up for the optical blemishes brought on by astigmatism, laser eye surgery uses an extra irreversible remedy by reshaping the cornea to improve its concentrating capacity.
Laser eye surgical treatment for astigmatism commonly involves making use of two main strategies: LASIK (Laser-Assisted Sitting Keratomileusis) and PRK (Photorefractive Keratectomy). Both treatments aim to deal with astigmatism by improving the cornea, but they vary in the means the external layer of the cornea is accessed.
LASIK is the much more popular selection amongst clients because of its faster recovery time and less pain compared to PRK. In LASIK, a thin flap is created on the cornea using either a microkeratome blade or a femtosecond laser. The flap is then lifted, as well as an excimer laser is utilized to improve the underlying cornea. Lastly, the flap is repositioned, acting as an all-natural bandage.
On the other hand, PRK involves the elimination of the outer layer of the cornea (epithelium) to access the underlying cells, which is then reshaped using an excimer laser. As PRK does not entail the production of a corneal flap, the recuperation period is much longer, and discomfort might be a lot more pronounced in the days complying with the treatment. Nonetheless, PRK is commonly advised for individuals with thin corneas or other contraindications for LASIK.
Both LASIK as well as PRK have actually shown excellent success prices in treating astigmatism. The majority of patients experience a substantial enhancement in their visual acuity, often attaining 20/20 vision or better. Nevertheless, it is crucial to consult with an experienced ophthalmologist who can examine your specific situation and also establish one of the most ideal treatment option for you.
Finally, laser eye surgery provides a life-changing opportunity for people with astigmatism to achieve more clear vision. Whether you select LASIK or PRK, the procedure can successfully reshape the cornea and appropriate astigmatism, ultimately improving your quality of life. If you are considering laser eye surgery, talk to a qualified eye specialist to discuss your alternatives and determine if you are a suitable candidate.
