Using the accuracy and precision of the Excimer Laser, Lasik changes the shape of the cornea to improve the way light is focused or refracted by the eye. Adjusting the pattern of the laser beam through a computer, it is possible to treat high levels of nearsightedness, farsightedness and astigmatism. Lasik eliminates or dramatically reduces a patient’s dependence on eye glasses or contact lenses. Lasik surgery is performed as an outpatient procedure in the comfort and convenience of the excimer laser surgical suite. The entire Lasik Laser Surgery vision correction procedure takes about 25 minutes to complete and both eyes can be done the same day. The Lasik Surgeon performs the procedure using topical anesthesia (eye drops). Patients notice a dramatic improvement in their vision on the very first day. Most patients return to their normal activities within a day or two.
Patients are always amazed by the speed and procedure of the Lasik procedure. Only topical anesthesia drops are used to numb the eye. Lasik Surgeon Los Angeles inserts an eyelid holder to prevent blinking while the drops eliminate the reflex to blink. Los Angeles Lasik Surgeon then uses an automated microsurgical instrument called a “microkeratome” to create a thin corneal flap which remains hinged beneath the upper eyelid. Corneal flap making has been researched and developed for 40 years, assuring a long history of safety and stability. Utraviolet light from the excimer laser then reshapes the internal cornea with an accuracy of 1/2000th of a millimeter, as per the patients’ necessity.
This changes the refractive power of the cornea thus eliminating the refractive error of the eye. Subsequently, the corneal flap is repositioned and the flap and interface are rinsed. Since the protective layer remains intact with Lasik, no bandage or contact lens is required. Patients are able to travel by air immediately and exercise after one week. Lasik eye surgery has rapidly changed the way millions of people see the world since 1997. It is estimated that over three million Lasik eye surgeries have been performed since then. Lasik has made it possible for almost anyone with poor vision to greatly improve the quality of their life through this sought-after surgery.
