LASIK eye surgery can mark the end of corrective lenses. But this is not suitable for everyone. Can you have LASIK with astigmatism?
What is the LASIK eye surgery?
There are several varieties of laser refractive surgery. LASIK is the best known and most often performed. Many articles, including this one, will use the term “LASIK” to refer to all types of laser eye surgery.
Usually, the images focus on the retina at the back of the eye. In the case of myopia (nearsightedness), farsightedness (hyperopia) or astigmatism, they end up focusing elsewhere, which causes blurred vision.
Short-sightedness (nearsightedness) is a condition in which you can clearly see objects nearby, but distant objects are blurred. When the eyeball is slightly longer than usual or when the cornea is too sharply curved, the light rays focus in front of the retina and blur the distant field of view. You can see objects that are closer, but not those that are far away.
Far-sightedness (hyperopia) is a condition in which you can clearly see distant objects, but nearby objects are blurred. When you have an eyeball that is shorter than average or the cornea is too flat, the light focuses behind the retina instead of on it. It blurs near and sometimes distant vision.
Astigmatism causes general blur of vision. When the cornea bends or flattens unevenly, the result is astigmatism, which disturbs the focus of near and far vision.
LASIK eye surgery is fast and safe
LASIK, performed on an outpatient basis, can take about 20 minutes – “and most of this time is spent preparing for surgery.
Recipients who are awake can receive Valium to calm their nerves. For protection and peace of mind, the laser is designed to turn off when the patient’s eye makes sudden movements that may cause an error or injury.
The results appear quickly
You don’t have to look long. LASIK patients will notice the difference in a few hours. “The next day you see really well. Most normal activities can be resumed within 48 hours.
However, those who receive PRK can expect a longer recovery – about a month – and slight pain due to removal of the corneal surface.
LASIK borders for astigmatism
There are certain corneal diseases, such as keratoconus, which can cause astigmatism in a patient due to general corneal instability. Keratoconus causes a gradual weakening of corneal tissue, which causes patients to develop more astigmatism over time. In this particular case, LASIK or PRK should not be performed, as this would threaten the already delicate corneal structure. Dr. Mozayeni’s vast experience and knowledge as a scholarship trained cornea specialist is crucial to ensure that you are a good candidate for LASIK eye surgery.
