History LASIK
Over the years, especially in the second half of the 20th century, rapid advances have been made in the field of ophthalmology. Visit Here Now http://lasiksurgery-services.blogspot.com
Earlier eye surgery is a complex procedure which involves invasive surgery and long recovery periods. The invention of the laser changed all that. Its use in a wide variety of fields including surgery the eye as well.
While LASIK surgery was developed in 1990 by Dr. Ioannis Pallikaris of Greece and Dr. Lucio Buratto of Italy, the concept of LASIK was formulated in 1970. In that year, Dr. Jose Barraquer microkeratome came with the first official. A microkeratome is a device used to alter the shape of the cornea, a central component of the eye, through the reduction of fine fins thereof. This process was called keratomileusis. Keratomileusis was a procedure to correct refractive of the cornea. This was accomplished by removing a deep layer of the cornea, freezing it, altering its curvature in the new one and replace it.
LASIK is short for a surgical procedure of the cornea – laser-assisted in situ keratomileusis. This procedure was developed jointly by the two doctors previously appointed by the fusion of two techniques – keratomileusis, which I described before, and keratectomy. LASIK surgery is now widely used because of two important reasons:
• Improved accuracy compared to other previous corrective procedures involving the eye or cornea.
• Minor complications compared with other existing techniques of his time.
In the United States, the first LASIK surgery was performed by Dr. Stephen Brint and Dr. Stephen Blade in 1991. In Germany, the first LASIK surgery was performed in 1991 by Dr. Tobias and Dr. Thomas Neuhann using an automatic keratometer.
As a side note, there is the hair removal procedure with LASIK. This is a procedure where extra hair anywhere on the body can be removed by Following the destruction of the hair follicle.
The LASIK procedure
LASIK surgery is performed in two stages:
• The pre-operational stage
• The operation itself
During the pre-operational stage users of contact lenses are asked to refrain from using for them a variable period of a week to 10 days. Initial examinations of the patient's cornea is performed to detect irregularities in the shape of the cornea, such as astigmatism. The test is done using a computer-controlled scanner that low-power laser shots to create a map of the cornea of the person. The surgeon prepares the coordinates of the surgery – the amount of corneal tissue to be removed, the location of the tissues, etc. the patient is also advised to use a mild antibiotic to reduce the chances of getting infected surgery Corneal post-LASIK.
At the beginning of the operation the patient is given local anesthesia in the form of a drop in the eye. The patient is usually awake during the procedure, which however can be given a sedative. The initial incision is made using a microkeratome or a and a femtosecond laser corneal flap at the designated cut. Thus, the flap is folded back to expose the stroma, which is the mid-section of the cornea. Then an excimer laser is used to reset the stroma.
Throughout the process, eye position is tracked by a computer, at a rate of 4,000 times per second.
LASIK Eye Surgery Complications
While LASIK surgery has its advantages, has some side effects. LASIK surgeons noted that there may be complications of LASIK surgery, although these are not too common.
After of LASIK surgery, a patient may find any of the following:
• Halo / flashing light sources near
• Visual fluctuation acuity,
• Under / over-correction
• Double vision
• Stretch marks, or wrinkles in the corneal flap
• The erosion of the epithelium
• Induced astigmatism
• Sensitivity to light
• Offset ablation
Different LASIK
The popularity of LASIK as a surgical procedure has ensured the proliferation of LASIK centers in all States USA. I probably could have a LASIK center right around the corner! Different centers use different procedures LASIK eye LASIK. In this section we take a look some of the procedures offered in different parts of the United States, and also look at some new procedures that are used today.
Conventional LASIK: This is the traditional method of performing LASIK, in which the corneal flap is cut with a knife or a microkeratome. While this process has its own merits, demerits include the possibility of flap-related complications, such as:
• Folded flap
• Displaced flap
• Slipped flap
• The DLK
• Epithelial ingrowth
Bladeless LASIK: This implies that the incision made with any other laser, a femtosecond or IntraLase. This minimizes the risk of complications that may arise from USNG a microkeratome LASIK.
LASEK Eye Surgery: Laser epithelial keratomileusis (LASEK) is a variation of the traditional LASIK surgery. It is performed by a surgeon specializing in LASIK in a patient whose cornea is too thin for LASIK to be performed. An alcohol solution is used to make removal easier epithelium. The disadvantage is that it involves a period greater recovery compared to traditional techniques of LASIK surgery.
Epi-LASIK: Laser in situ epithelial keratomileusis (Epi-LASIK) is another type of LASIK procedure attempts to bring together the best of LASIK, PRK and LASEK. Epi-LASEK cuts out the complications that can arise from LASIK, and also allows the patient faster recovery than PRK or LASEK.
WaveFront LASIK or Custom Wavefront: Wavefront LASIK or Custom Wavefront LASIK is a procedure that provides high-precision corrections to defects in the cornea. The degree of precision is much better than that given by lenses or conventional LASIK. This is possible because Wavefront LASIK uses three dimensional measurements of image processing capacities of the human eye to help reorganize the laser of the cornea to remove corneal defects.
With the advent of wavefront LASIK, you can also improve the quality of their vision, in terms of being able to see things better in terms other than those normally as possible. It allows one to increase contrast sensitivity of the eye. Studies show that increased contrast sensitivity almost twice that of LASIK. Visit Here Now http://lasiksurgery-services.blogspot.com
