History of LASIK
Over the years, especially in the second half of the 20th century have made rapid progress in the field of ophthalmology. Before eye surgery is a complex procedure involving minimal invasive surgery and a long recovery periods.The invention of the laser changed all that., its use in a wide variety of areas included eye surgery as well.
While LASIK surgery itself developed in 1990, Dr. Ioannis Pallikaris Greece and Dr. Lucio Buratto from Italy, the concept itself was developed by LASIK, in 1970. This year, Dr. José Barraquer came out with the first official mikrokeratom. Mikrokeratom device allows you to change the shape of the cornea, the centrepiece of the eyes, a thin flap of cutting it.This process was called keratomileusis. Keratomileusis is a procedure to correct the refractive corneal surgery.This was achieved by tackling profound corneal Flake freeze it, changing its curvature to the new database and then replace it.
LASIK is an abbreviation of corneal surgery-laser In Situ Keratomileusis. this procedure was developed in co-operation with two doctors, listed above, the merger of the two methods-keratomileusis, which I mentioned earlier, and photorefractive keratectomy. LASIK eye surgery is widely used at present for two important reasons:
o improved accuracy in comparison with other earlier remedial procedures associated with the eye or cornea.
o Lesser complications compared with other existing methods of his time.
In the United States, Dr. Stephen Brint and Dr. Stephen Blade in 1991, the first LASIK surgery in Germany the first LASIK surgery was performed in 1991 the Tobias Neuhann Dr. and Dr. Thomas, using automated keratoma.
Note this procedure used to remove hair LASIK.This procedure can be removed excess hair in any part of the body by eliminating root hair follicle.
LASIK Procedure
LASIK eye surgery is performed in two stages:
o the Pre-operative phase
o operation itself
During the pre-operative phase of contact lens users are asked to refrain from wearing them for a period ranging from from a week to 10 days to identify irregularities in corneal shape, such as astigmatism are the initial inspection of a cornea patient exam takes place using computer-controlled scanner that shots of low power lasers to map individual cornea. Surgeon prepares coordinates for surgery to remove corneal tissue-, location etc., patients also use mild antibiotic to reduce the chances of a cornea, getting infected post LASIK surgery.
At the start of the operation, the patient is managed localized anesthetic eye drops are usually awake patient during the procedure; however, it can be given a sedative initial incision is made using a Femtosecond laser and mikrokeratom or cut a flap in the cornea to the designated address. in doing so, the flap is folded back to stroma, which is the forest of the cornea. excimer laser is used to justify the stroma.
All through the process of the eye is tracked using a computer with a speed of 4 000 times per second.
LASIK eye surgery complications
While LASIK surgery has its advantages, it has some side effects, a. Surgeons LASIK eye surgery that can be complications from LASIK surgery, although they did not see very often.
After LASIK surgery, the patient may experience with any of the following:
o Halo/zasvetov near sources of light
o Visual acuity fluctuations
o/overcorrection
o double vision
o Striae or wrinkles in the corneal flap
o skin Erosion
o Induced astigmatism
o Sensitivity to light
o Decentered ablation
Different procedures for LASIK
As the popularity of LASIK surgery is multiplying LASIK centers across the United States probably can have LASIK Center just around the corner! Various centers of LASIK eye surgery with LASIK through various procedures in this section, we'll take a look at some of the procedures offered in various parts of the USA, as well as a look at some new procedures currently in use.
Conventional LASIK: LASIK is the traditional method of doing the corneal flap blade is cut or mikrokeratom. Although the process has its advantages, disadvantages include the possibility of complications related to a flap, such as:
o Folded flap
o Displaced flap
o Slipped flap
o Diffusion lamellar Keratitis
o Epithelial ingrowth
Bladeless LASIK: This includes after the cut, made using another or by intralase Femtosecond laser, it minimizes the risk of complications that can arise from LASIK usng mikrokeratom.
LASEK eye surgery: Laser Epithelial Keratomileusis (LASEK) is a type of traditional LASIK surgery is done by LASIK Surgeon for a patient whose cornea is too thin for LASIK performed. alcohol solution is used to facilitate removal of epithelium. the drawback is that this entails for a longer period of reconstruction, as compared to traditional LASIK surgery.
EPI-LASIK: laser In Situ Keratomileusis Epithelium (Epi-LASIK) is another type of LASIK procedure that tries to combine the best of LASIK, PRK, LASEK. EPI-LASEK cuts the complications that may arise from LASIK, and allows the patient to faster recovery time than PRK or LASEK.
WaveFront LASIK and Wavefront LASIK: Wavefront Setup or customize a Wavefront is LASIK procedure that provides high accuracy of correction of corneal defects. accuracy is many times more lenses or even conventional LASIK. This is perhaps because Wavefront LASIK uses three dimensional dimension Imaging abilities of the human eye to help redeploy corneal laser to remove corneal defects.
With the advent of Wavefront LASIK can also improve the quality of their vision in terms of being able to see things better under different conditions than normally possible. improves contrast sensitivity. studies have shown that the increase in contrast sensitivity in nearly twice as much as LASIK.
Although it is difficult to determine which one best LASIK procedure most reasonable do will understand that each process has its advantages and is suitable for particular situations and scenarios with different LASIK vision centres providing different kinds of LASIK procedures, one has the luxury of making comparisons of different options in terms of usability, price, etc., and then select the procedure best suited his needs.
