LASIK is an FDA-approved refractive correction procedure for myopia (nearsightedness), hyperopia (farsightedness), and other vision problems. It stands for laser-assisted in situ keratomileusis.
In simple terms, an ophthalmologist performs a thin, hinged flap incision further into the cornea. A laser then removes inner layers of the cornea to provide it with adequate curvature.
When compared to other corneal surgeries, this laser eye surgery offers quicker and more pleasant recovery experiences.
Astigmatism is a type of refractive error, in which the curvature of the eye’s cornea or lens is irregular. The curvature is sometimes comparable to the shape of a football or egg. This eye condition can affect how light passes through the cornea and lens and refracts (bends) onto the retina. A refractive error of this kind can make viewing objects challenging.
When astigmatism is strong, different symptoms may arise, including:
Because of these problems, an eye doctor may recommend LASIK surgery as a treatment option.

LASIK surgery has many advantages for those with astigmatism, including:
Laser vision correction procedures may vary in price according to different factors.
In general, the average cost of LASIK in the United States is around $2,500 per eye.
This price may include the initial consultation as well as follow-up care. However, as each eye care clinic is different, it is important to speak with the ophthalmologist about an itemized quote.
Additional factors that may influence costs for this type of refractive surgery include:
If an individual decides not to undergo LASIK surgery, there are other options available.
Before determining treatment and/or corrective lenses, an eye doctor will perform an eye exam to understand the cornea’s shape.
In many cases, individuals can address mild to moderate astigmatism problems with eyeglasses or contact lenses. One example is a type of soft lenses called toric contact lenses. However, it may be more suitable for individuals who have severe astigmatism to wear rigid contacts or glasses.
Another treatment option is photorefractive keratectomy (PRK). This surgical procedure is similar to LASIK. However, the surgeon does not leave the cornea’s outer protective layer as a flap. Instead, the layer is removed, and the tissue grows back naturally to fit the reshaped cornea.
A primary reason why individuals may be a good candidate for PRK than LASIK is corneal thickness. If the cornea is too thin, there is not enough tissue for surgeons to create a flap in the superficial layer of the cornea. This step is essential in LASIK surgery.
However, individuals who consider undergoing PRK should know that recovery time is different from that of LASIK. With PRK, recovery periods are often much longer.
In any case, it is always best to stop by an ophthalmology clinic and speak with an eye health professional about any invasive or non-invasive treatment options.
