Are you suffering from a refractive disorder called “Astigmatism”? Did you know there are 3 types of laser eye surgery astigmatism procedures that you could choose from to free yourself from years of visual impairment?
Well, this must be your lucky day because we have summarized these 3 commonly practiced laser eye corrections available now at reputable laser eye centers near you. Why wait, reward yourself a near to perfect vision and see the world on a brighter side. Decide later which among these modern approaches fits your visual need, health condition and expectations.
Astigmatism is a type of refractive error that is resulted from the abnormal curvature of the patient’s cornea or lens. People with astigmatism often complain of blurry or distorted vision. There are certain factors that may cause astigmatism such as:
Irritations due to some prior eye surgical procedures
Other reasons why a person may develop astigmatism are due to one’s genetic formation (congenital) such as keratoconus resulting to the abnormal shaping of the cornea.
How can Astigmatism be corrected?
The usual medical approach to correct a person’s astigmatism is through the assistance of contact lenses, inflexible contact lenses, oxygen permeable contact lenses and soft toric contact lenses. When contact lenses are not performing as expected to resolve the refractive error, the last resort is an eye surgery procedure that must only be performed by a certified eye surgeon who has specializations on the area of corneal treatment.
This is the latest and most practical type of laser eye treatment that any individual with astigmatism and other refractive errors like myopia or hyperopia must consider. The Lasik surgery uses a precision blade known the “microkeratome” in order to create a small incision on the outer layer or epithelium of the cornea. Then, it is carefully lifted out and an excimer laser is used to reshape the cornea.
LASEK is also referred as “laser-assisted subepithelial keratomileusis” is another surgical procedure ideal for t with very steep or thinner cornea. Here, the skinny epithelial layer of the cornea is preserved wherein the eye surgeon uses a top performing blade to cut the epithelium of the cornea and the alcohol resolution is put to the target to loosen the outer layer of the cornea. Then, the surgeon uses a laser to reshape the outer part of the cornea. Once, the reshaping is done, the epithelial flap is put into place. Unlike the Lasik treatment, the LASEK may need extended therapy time.
Another corrective solution to treat astigmatism is the Prk eye surgery which requires the removal of the outer layer of the cornea for the purpose of modifying its shape. The outer layer or epithelium is removed and an excimer laser is used to reshape the cornea. This kind of surgery is sometimes called “floor ablation” and the ideal candidates for this treatment are those individuals with thin corneas.
In today’s more advanced medical technologies, anyone diagnosed with astigmatism can have the freedom to choose the most applicable laser eye surgery that can deliver the ultimate visual improvement.
