If you should sneeze or cough, the laser will wait or adjust its position to compensate. This technology means that sneezing—as well as coughing or any other involuntary movement—will not affect the result of your surgery.

Can you get Lasik twice?

A second procedure is necessary if refractive errors were not corrected during LASIK. If a second procedure has been deemed necessary, another flap will be created. Most surgeons won’t perform a second LASIK procedure unless it’s 5-10 years after LASIK.

What is the prescription limit for laser eye surgery?

‘ This is the degree to which your vision needs correcting, measured in diopters by ophthalmologists. Advanced lasers now can treat up to +6.00 diopters of hyperopia, 6 diopters of astigmatism, and up to -12.00 diopters of myopia, depending on which type of laser gets used for the surgery.

What can disqualify you from Lasik?

Can you get Lasik If you have really bad vision?

Yes, it can. However, you must also meet other requirements outside of prescription limits in order to be a good candidate for LASIK. These include: Having corneal tissue that’s thick enough — approximately 420 microns — for LASIK.

Can Lasik be done for high power?

It is not correct as treatment of power more than -8.0 leads to excessive flattening of the cornea and resultant disturbances in a vision called a spherical aberration. It is therefore recommended that the ideal upper limit is -8.0, while the acceptable upper limit is -10.0.

Who is not suitable for laser eye surgery?

For example, if you are pregnant or breastfeeding, the surgery is not suitable because fluctuating hormones can affect a person’s vision.
