The LASIK Procedure

LASIK eye surgery is carried out in two phases:

During the pre-operative phase contact lens customers are asked to refrain from using them for a period differing from between a week to 10 days. First evaluations of the cornea of the person are made to discover abnormalities in corneal shape, such as astigmatism. The exam is done utilizing a computer-controlled scanner that shots low-power lasers to create a map of the individual's cornea. The surgeon prepares the collaborates for the surgery - the amount of corneal cells to be removed, the place of the cells, and so on the patient is likewise advised to utilize a light antibiotic to minimize the opportunities of the cornea getting contaminated post-LASIK surgery.

At the beginning of the operation the individual is administered local anesthetic in the form of an eye decrease. The person is usually awake throughout the treatment; he may nonetheless be given a sedative. The preliminary laceration is made using a microkeratome or a femtosecond laser and also a flap of the cornea at the designated place is reduced. In doing so, the flap is folded back to subject the stroma, which is the mid-section of the cornea. Next an excimer laser is used to realign the stroma.

Throughout the process, the placement of the eye is tracked by a computer, at speeds of 4,000 times per secondly.

LASIK Eye Surgery Complications

oFolded flap

oDisplaced flap

oSlipped flap

oDiffuse lamellar keratitis

oEpithelial ingrowth

Bladeless LASIK: This involves having the cut used an additional laser, a femtosecond or IntraLase. This minimizes the danger of issues that might arise out of a LASIK usng a microkeratome.

LASEK Eye Surgery: Laser Epithelial Keratomileusis (LASEK) is a variation of the standard LASIK surgery.

Epi-LASEK cuts out the problems that can occur out of LASIK, as well as additionally permits the person a faster recovery time than PRK or LASEK.

WaveFront LASIK or Customized Wavefront: Wavefront LASIK or Customized Wavefront is a LASIK procedure that supplies high accuracy improvements to corneal issues. The degree of precision is often times sharper than that provided by lenses and even traditional LASIK. This is feasible due to the fact that Wavefront LASIK makes use of 3 dimensional measurements of the image-processing abilities of the human eye to aid the laser reorganize the cornea to get rid of corneal flaws.

With the arrival of Wavefront LASIK, one can likewise enhance the top quality of their vision, in regards to having the ability to see points far better in different circumstances than normally possible.
