The second step of the LASIK method is to utilize an excimer laser (193 nm) to rebuild the corneal stroma. The laser disintegrates tissue in a finely controlled way without harming the neighboring stroma. No igniting with heat or genuine slicing is expected to remove the tissue. The layers of tissue eliminated are many micrometers thick. Playing out the laser removal in the further corneal stroma regularly accommodates more quick visual recuperation and less torment than the prior strategy, photorefractive keratectomy (PRK).
During the subsequent step, the patient's vision will turn out to be exceptionally foggy once the fold is lifted. They will actually want to see just white light encompassing the orange light of the laser, which can prompt gentle bewilderment.
Presently fabricated excimer lasers utilize an eye global positioning framework that follows the patient's eye position up to 4,000 times each second, diverting laser beats for exact situation inside the treatment zone. Common heartbeats are around 1 millijoule (mJ) of heartbeat energy in 10 to 20 nanoseconds
