What Is Lasik
To know what is Lasik it is important to know what the word stands for. The word LASIK stands for Laser-Assisted In Situ Keratomileusis. Lasik is a procedure that permanently changes the shape of the cornea using the excimer laser. That is what is lasik in a nutshell. To address the question what is lasik though is not that easy.
Lasik technology is quite complicated. We cannot know what is lasik if we do not know the different types of refractive errors. These are: myopia, hyperopia and astigmatism. Myopia pertains to nearsightedness. Hyperopia refers to farsightedness and astigmatism pertains to a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye.
What is Lasik can be determined in its effects. Lasik surgery enables the patient to undergo precise and controlled removal of corneal tissue by a special laser which reshapres the cornea. There are other types of refractive surgery which are different from what is lasik. There is radial keratotomy or RK and photorefractive keratectomy or PRK.
The same type of Laser is used for Lasik and PRK. In PRRK, the top layer of the cornea called the epithelium is scraped away to expose the stromal layer underneath. What is lasik is to cut a flap in the stromal layer and flap is folded back. The use of lasers similar to that of PRK to treat refractive errors define largely what is Lasik in layman’s terms. Over the last years, doctors used Lasik as main surgery for treating myopia.
Before undergoing the Lasik surgery make sure that you do your part to prepare aptly for the procedure to prevent possible negative consequences. The Lasik procedure takes only thirty minutes to complete. If you cannot focus your eyes for 60 seconds then you may not qualify for a Lasik procedure. Make sure that you’ve made proper inquirers pertaining to the treatment before undergoing the procedure.
What is lasik is determined mostly by what it does. If you are not a risk taker or if your job prohibits refractive procedure or cost is an issue, then probably lasik treatment may not be the procedure for you. Do not sign any waiver before you are made aware of the risks and benefits involve with Lasik surgery. What you do before and during surgery are as important as what you do after it. Make sure that you follow doctor’s orders to ensure your safety.
