New lasik is one of many surgical options for correcting faulty vision. The most popular refractive surgery procedure, lasik or laser assisted in situ keratomileusis is also the most frequently performed. It is most beneficial for nearsighted, farsighted and astigmatic individuals. However, not everyone with the said eye problems, qualify for a lasik San Diego.

Lasik eye center, lasik new, lasik new york, new lasik or lasik san diego, how exactly does a lasik work? The goal of a lasik is to reshape the cornea into its proper form. In nearsighted individuals, the too-steep cornea is flattened , in farsighted people, the cornea is made steeper, while in astigmatics, the irregular cornea is smoothed into a more normal form. Once the cornea is shaped correctly, it works better at focusing light into the eyes and onto the retina, resulting in clearer vision.

These results are achieved by first creating a thin circular covering or flap in the cornea, with the use of an instrument named microkeratome. A surgeon then creases the flap and removes corneal tissue underneath with the use of a cool ultraviolet light beam sourced from an excimer laser. The light beam is capable of removing the tiniest bits of corneal tissue, aimed at reshaping the cornea. The flap is then placed back in position, covering the area where corneal tissue was removed.

Lasik san diego is popular because it is virtually pain-free and results are achieved almost right away. In fact, not counting from the time you walk into a lasik eye center, the actual surgery takes less than sixty seconds, with the patient conscious the entire time. Before a procedure, the surgeon will anesthetize your eyes with special drops and at times administer a mild oral sedative. You are then made to lie down with the laser positioned directly over your eye and a retainer in place to keep your eyelids open. This is meant to keep your eye pressurized so that the surgeon can cut the corneal flap. Next, an ink marker will be used to mark the area where the surgeon will place the flap, and a computer will be used to adjust the laser fit for your prescription. Finally, you are made to stare at a target light while the laser sends light pulses to your cornea, painlessly removing the tissue. Immediately after, you are sent home to rest for a few hours.

There are also other alternatives to new lasik like custom and bladeless lasik. Consult with your eye surgeon to know what procedure works best for you.
