Astigmatism Correction with iLASIK
In a majority of the astigmatism cases, bladeless LASIK has proven to be an effective and permanent treatment. Astigmatism is considered to be one of the most common vision related problems. It is not a disease, just an eye condition or refractive error similar to farsightedness and nearsightedness. There are numerous ways to correct astigmatism including LASIK surgery, contact lenses, and eyeglasses.
The normal shape of your cornea appears to be like a baseball. But when a person has astigmatism, the cornea changes shape and starts to resemble a football rather than a baseball. Another common analogy used to explain astigmatism is that the eye takes the shape of an egg, instead of looking like a regular ping-pong ball. Since the cornea shape is altered, the bending of light is hampered when it enters your eye. This ultimately leads to blurriness or vision distortion. Some astigmatism patients might squint quite frequently in an attempt to see more clearly. This is because astigmatism could make it difficult to view fine objects/details. Constant squinting may lead to headaches because you experience a lot of strain with constant focusing.
iLASIK for astigmatism
The iLASIK procedure is often used for correcting astigmatism and the treatment usually depends on the severity and type of astigmatism. LASIK makes use of ultra-precise lasers that are programmed for reshaping the cornea. The procedure helps give a more symmetrical shape to the front eye surface and eliminates astigmatism-related vision problems. Astigmatism usually does not go beyond the magnitude of 3.0 diopters (D) and a LASIK procedure can fully correct it. Laser-assisted in situ keratomileusis (LASIK) is often used for reshaping the inner cornea layer with the aim of correcting astigmatism. It is vital to know the type and extent of astigmatism before opting for any treatment option. Your eye doctor can help choose a suitable LASIK surgery for you after doing a detailed diagnosis of your eye.
Generally speaking, the majority of the patients who have undergone laser-assisted in-situ keratomileusis (LASIK) get at least 20/25 vision and this works quite well for almost all activities. LASIK eye surgery has so far been reported as an excellent treatment option for those with moderate/mild astigmatism. This eye surgery is also highly recommended for those people who are physically active (for example, sportspersons or athletes) and find it difficult to wear contact lenses or eyeglasses on a daily basis.
