LASIK is becoming a popular alternative of traditional eye treatments like spectacles or contact lenses. It is, therefore, better to know about LASIK before you decide whether to go for LASIK or not. What is LASIK? LASIK is an abbreviation of Laser-assisted In Situ Keratomileusis. In this process, the affected eye is exposed to laser rays for rectifying the defects thus it is a laser eye surgery. It is often used to treat nearsightedness or farsightedness.
In our eyes, light reaches the retina through the cornea and lens. Any error from the cornea or lens results in blurry image, which is known as refractive error. This is when LASIK comes into play. A laser beam is used to rectify any anomaly in the cornea or lens. After careful examinations and tests, an ophthalmologist decides how much corneal tissue is to be removed to treat the error.
LASIK isn't a long process however it is an advanced treatment and requires sophisticated machines. Generally, for one eye, LASIK takes around 15-30 mins.
The process involves a few steps. Firstly, anaesthetic eye drops are used to get the eye numb. Then microkeratome is used and a small corneal flap is cut to expose the corneal tissues. Then the cornea is exposed to the laser to reshape the cornea. Then the corneal flap is placed back on again. As we can see, no needle or stitches got involved in the whole process. And as everything is done by sophisticated and fine tuned machines, there is nothing to fear about this process. There can be an itchy feeling in the eyes after this operation so an eye patch is required to wear. However, body's immunity can soon restore the perfect condition of eyes and you can remove the patch after 8-10 hours.
LASIK can't be performed on everybody. For example, pregnant women or breastfeeding mothers can't go for LASIK as their eyes are not in a normal state. Also, people taking drugs like acetone or prednisone are not eligible for LASIK. Age is another determining factor and diseases like diabetes where body's immunity is reduced make LASIK difficult. Among all these people, disqualified for LASIK, some may opt for LASEK if the physician approves.
LASIK has its own drawbacks or risks as well. Dry eyes, infection of cornea, itchiness are some side effects few people developed after LASIK albeit rarely. You must judge both the sides before going for LASIK. If these risks are too scary for you, and if you haven't any problem with wearing glasses or contact lenses, then you can do without LASIK, if you desire so.
