An Introduction to LASIK



Throughout the years, particularly in the last fifty percent of the 20th century, rapid improvements have been made in the field of ophthalmology. Earlier eye surgery was a complex treatment involving invasive surgery and also lengthy healing durations. The innovation of the laser altered all that. Its use in a wide array of fields included eye surgery as well.

LASIK surgery was itself created in 1990 by Dr. Ioannis Pallikaris of Greece and also Dr. Lucio Buratto of Italy, the principle of LASIK itself was developed in 1970. In that year, Dr. Jose Barraquer brought out the very first official microkeratome. A microkeratome is a tool utilized to alter the form of the cornea, a central component of the eye, by reducing slim flaps of it. This process was called keratomileusis. Keratomileusis was a procedure to deal with the refraction of the cornea. This was accomplished by eliminating a deep corneal lamella, freezing it, modifying its curvature into a brand-new one, and then replacing it.

LASIK is the acronym for a surgical procedure of the cornea - Laser-assisted Sitting Keratomileusis. This treatment was collectively developed by the 2 doctors called above by the fusion of two methods - keratomileusis, which I have defined previously, and also keratectomy. LASIK eye surgery is really commonly made use of nowadays due to two crucial reasons:

oImproved precision compared to other earlier restorative treatments including the eye or cornea.

oLesser complications compared to various other existing techniques of its time.

In the United States, the very first LASIK surgery was done by Dr. Stephen Brint and Dr. Stephen Blade in 1991. In Germany the very first LASIK surgery was executed in 1991 itself by Dr. Tobias Neuhann and Dr. Thomas making use of an automated keratome.

AS a side note, there is also the LASIK hair removal treatment. This is a procedure where added hair in any type of part of the body can be removed by destroying the origin of the hair roots.

The LASIK Procedure

LASIK eye surgery is performed in 2 stages:

oThe pre-operative phase

oThe operation itself

Throughout the pre-operative phase get in touch with lens users are asked to avoid using them for a duration varying from between a week to 10 days. Initial exams of the cornea of the individual are made to spot abnormalities in corneal form, such as astigmatism. The evaluation is done using a computer-controlled scanner that shots low-power lasers to develop a map of the individual's cornea. The cosmetic surgeon prepares the coordinates for the surgery - the quantity of corneal cells to be removed, the area of the cells, etc. the person is likewise advised to make use of a moderate antibiotic to reduce the opportunities of the cornea getting infected post-LASIK surgery.

At the start of the procedure the patient is provided localized anesthetic in the form of an eye drop. The individual is usually awake throughout the procedure; he might however be provided a sedative. The initial cut is used a microkeratome or a femtosecond laser as well as a flap of the cornea at the designated place is cut. In doing so, the flap is folded up back to reveal the stroma, which is the mid-section of the cornea. Next an excimer laser is utilized to straighten the stroma.

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

LASIK Eye Surgery Issues

While LASIK surgery has its benefits, it has a few side impacts. LASIK eye doctors point out that there might be difficulties occurring out of LASIK surgery, though these are not also frequently seen.

After LASIK surgery, a person may come across any one of the following:

oHalo/starbursts near sources of light

oVisual skill fluctuation

oUnder/overcorrection

oDouble vision

oStriae, or wrinkles in the corneal flap

oErosion of the epithelium

oInduced astigmatism

oSensitivity to light

oDecentered ablation

Various LASIK Procedures

The popularity of LASIK as a medical treatment has made sure the mushrooming of LASIK facilities all across the United States. Different LASIK eye facilities make use of different LASIK procedures.

Standard LASIK: This is the traditional method of executing LASIK, in which the flap of the cornea is LASIK Dallas reduced utilizing a blade, or a microkeratome. While this process has its very own qualities, bad marks consist of the possibility of flap-related problems, such as a:

oFolded flap

oDisplaced flap

oSlipped flap

oDiffuse lamellar keratitis

oEpithelial ingrowth

Bladeless LASIK: This includes having actually the laceration used an additional laser, a femtosecond or IntraLase. This lessens the threat of complications that may arise out of a LASIK usng a microkeratome.

LASEK Eye Surgery: Laser Epithelial Keratomileusis (LASEK) is a variation of the traditional LASIK surgery. It is carried out by a LASIK cosmetic surgeon on a patient whose cornea is too thin for LASIK to be executed.

Epi-LASIK: Epithelial Laser Sitting Keratomileusis (Epi-LASIK) is another sort of LASIK procedure that attempts to combine the very best of LASIK, PRK and LASEK. Epi-LASEK eliminate the problems that can arise out of LASIK, as well as likewise allows the person a much faster healing time than PRK or LASEK.

WaveFront LASIK or Customized Wavefront: Wavefront LASIK or Customized Wavefront is a LASIK procedure that gives high accuracy adjustments to corneal defects. The level of precision is sometimes sharper than that provided by lenses or even standard LASIK. This is feasible because Wavefront LASIK makes use of 3 dimensional measurements of the image-processing capacities of the human eye to help the laser rearrange the cornea to remove corneal flaws.

With the arrival of Wavefront LASIK, one can additionally enhance the quality of their vision, in regards to being able to see points much better in different conditions than typically feasible. It allows one to improve the contrast level of sensitivity of the eye. Studies reveal that the boost on the other hand level of sensitivity in nearly 2 times that of LASIK.

While it is challenging to establish which of these is the very best LASIK procedure, the sensible point to do would be to understand that each procedure has its very own advantages and also is fit to specific circumstances and situations. With the different LASIK vision facilities providing various kinds of LASIK treatments, one has the luxury of making contrasts between the different choices in terms of use, price, and so on and then picking the procedure that a lot of suits his needs.


LASIK surgery was itself developed in 1990 by Dr. Ioannis Pallikaris of Greece and also Dr. Lucio Buratto of Italy, the concept of LASIK itself was developed in 1970. The popularity of LASIK as a surgical treatment has made certain the mushrooming of LASIK centers all throughout the United States. Different LASIK eye facilities use various LASIK procedures. It is carried out by a LASIK surgeon on an individual whose cornea is also thin for LASIK to be executed. WaveFront LASIK or Custom Wavefront: Wavefront LASIK or Custom-made Wavefront is a LASIK procedure that supplies high accuracy adjustments to corneal issues.
