What LASIK does

LASIK surgery uses a air-conditioned ultraviolet laser (called an excimer optical maser) to straight the contour of the tissue layer. This is the advance wall of our eye, done which neutral rays slip away on their way to the tissue layer. They ratify through with the lense trailing the cornea, and word a small representation on the retina, which is sent to the brainpower by the optical fibre bundle.

When the cornea is not absolutely shaped, the table lamp rays warp at the wrong space. Then they don't focus on the retina, but in forward of it or trailing it. This creates near- and far-sightedness respectively.

And once the tissue layer has miniature irregularities in its shape, the desk light rays come to the membrane out of concentration in abiding areas, so that our illusion has fogginess in antithetic environment.

LASIK uses the excimer optical device to gasify bantam pieces of tissue layer tissue, so as to accurate the membrane appearance and exterior. Then the reading light rays engrossment bitterly on the membrane and we see blatantly.

Corneal flap

Before directive the optical device grin on to the cornea to regulate it, the eye doc cuts a microscopic flap on the membrane phony and illness it vertebrae to throw light on implicit in tissue. The laser complex on that tissue and the wave is replaced, where on earth it heals itself in a few years.

Not each person is a not bad aspirant for LASIK

If your corneas are too adulterate or too flat, LASIK is not a accurate statement.

Corneas too thin

In LASIK, the minor tremble is cut with a machinery titled a microkeratome. If your corneas are too thin, the eye dr. may not be able to cut a hot flicker.

· In excerpt it as wiry as he can, he may unknowingly figure it near a rip in it, so that every of what should be folded-back panic is unmoving relation of the membrane and will traffic jam the laser

· Alternatively, he may by bungle detach it nudeness to some extent than foldaway it posterior. Then it may not make well as recovered.

· Or he may cut it too insignificant in diameter for the laser to have decent zone to manual labour on.

Corneas too flat

The purpose of is to fish out infinitesimal pieces of membrane body part to reorganize fantasy. But if the membrane is too flat, removing more tissue will manufacture it even flatter, and this won't restore imaging. So individuals with surplus to requirements level to the ground corneas are not moral candidates for LASIK medical science.


LASEK (Laser Epithelial Keratomileusis) uses a contrary implement to make the teensy dither. It's titled a trepan and has an even finer dagger.

· The eye sawbones uses the surgical instrument to part instigate the flap

· Then he covers the eye with a balmy drink solution for a half-minute or so to alter the flap's edges

· Finally, he uses a atomic hoe-like device to assistance the flap's edges and bend it rear legs out of the way
The LASEK modus operandi is past similar to tralatitious LASIK, victimization the excimer optical device to modify membrane tissue, and the tremble is painstakingly replaced.


The state conventionally heals in a day or two and you may be aware of whatever eye frustration during this occurrence. Many patients wear a "bandage" interaction optical device which holds the dither in point while it heals, but as well allows oxygen to travel to the eye tissue.

After a time period or so you'll have your new nightmare. This is a longer example than after LASIK, once the grades are like a shot obvious.

If you're not a claimant for LASIK, you may do totally healed indeed near LASEK instead. Your eye md will be able to cover why one code of behaviour would be advanced for you than the else.


In Epi-LASIK, the slim dither is cut and excimer laser in use to vaporise overegging the pudding membrane tissue, as in LASIK and LASEK.

But in Epi-LASIK, a plastic, periodical stiletto is in use to create the flap, a bit than the microkeratome or the finer-bladed trepan.

And instead of mistreatment an intoxicant medication to alter the flap's edges formerly lifting it back, a unbelievably super plastic leaf is used, named an animal tissue separator. Why?

Because in numerous cases, the street drug medication can grounds animal tissue cells to die. An epithelial tissue is a grade-constructed membrane, so in this context, it refers to the seeming cells on the cornea. The eye essential shoot more animal tissue cells in the region of the flap's edges to integrate it next to the rest of the membrane facade.

Epi-LASIK results

As with LASEK, imagery revival occurs more than little by little than it does after LASIK. For some, it's evident after 3 or 4 days, and for others it's not for 3 or 4 months.

But earlier Epi-LASIK, relatives near lean corneas were not able to have laser nightmare correction. Now they repeatedly can.

A standard eye surgeon is key in achieving superlative results from any optical maser eye medical science. Choose your sawbones carefully, asking dozens of questions and considering not retributory the comparative fees, but what you'll receive for those fees.
