The postoperative thickness of cornea stroma could not be allowed to lower than 250 micrometer, or the cornea will be too thin to stand the inner pressure of eyeball and swell outwards, the successive symptom will be keratoconus. So we must require the thickness of cornea before operation over 410 micrometers, and no matter which kind of Lasik surgery, this number of 410 micrometer is the lowest rate to start. The stronger prescription, the more cornea stroma will need to cut. The more thickness of the cornea, the more safety level of the surgery will be. Just now, you have not mentioned the actual details of your prescription before the surgery, so I have no mean to get the answer if you could accept this surgery. It is a important surgery for your eyes, so I suggest you go to the regular major hospital to check carefully before the treatment.
