Lasik Los Angeles surgery and its limitations of the treatment
Laser-assisted in situ keratomileusis (LASIK) is an outpatient surgery that corrects refractive errors such as myopia, hyperopia, and astigmatism by changing the shape of the cornea. For Lasik Los Angeles, anaesthesia is applied to the surface of the eye. If so, a thin notch is placed in the cornea using a surgical femtosecond laser or a mechanical microkeratome in the process of Lasik Los Angeles. The corneal tissue valve created by this cut looks like a contact lens hinged on one side. Lasik Los Angeles Uses an excimer laser to surgically retract the flap, treat the exposed corneal tissue below the flap and change its shape very precisely. Once done, the flip is returned to its original position and sealed within 12-24 hours.
Limitation of Lasik Treatment
Each corneal refractive surgery can treat several refractive errors. This presents the achievable therapeutic limits. The clinical situation of each eye must be taken into account (thickness of the cornea, the thickness of the valves, surgery before the optic zone, concomitant diseases of the eye, etc.). For Lasik Los Angeles, you should save tissue in case reinforcement is needed. One of our doctors will tell you if your eyes are suitable for a particular treatment. Cases outside the scope of treatment below are intraocular surgery. In most of the Lasik Los Angeles cases, natural lens exchange can be performed including the aphakic lens. The AlconWaveLight®EX500 laser system is approved for the wavefront optimization treatment of:
- Myopia with or without astigmatism: For patients over 18 years of age, documents are proving that the refractive power does not vary by more than 0.5 D at 1 year, with or without preoperative myopia, and myopia is greater than -12.0 D. Astigmatism test up to 6.0D previously.
- Hyperopia with or without astigmatism: in patients 18 years of age or older with written evidence, farsightedness has a maximum of +6.0 diopters, up to 5.0 D with or without astigmatism, and the apparent trial maximum before the preoperative examination is 6.0 diopters. The variation of their attempts over several years does not exceed 0.5D.
- Mixed astigmatism: In patients over 21 years of age, mixed astigmatism has a high value of 6.0 D, and there is evidence that the refractive power has not changed by more than 0.5 diopters throughout the previous year before the preoperative examination.
