LASIK Eye Surgery - Understanding of technical
In the world of medicine of the 21st century, many surgical procedures that fall under the general term for LASIK eye surgery "are becoming more complex. Those who consider LASIK surgery, then, could be explained by differences between the relevant procedures.
LASIK, which are directed towards the correction of astigmatism, myopia and fall into three categories. They are corneal incisions, flaps, andphotablation.
Corneal Procedures
The procedure of incision in the cornea, sometimes referred to as a keratotomy, it is appropriate in cases of misshapen corneas interfere with optical refraction. Average Poor blurred vision and refractive surgery LASIK, which reshapes the cornea will improve refraction. Family incision in the cornea are three slightly different approaches for LASIK.
For those with astigmatism, astigmatic keratotomy, or AK, involves the surgeon cutting and smoothing bulges in the cornea to produce a curve that allows a better refraction.
In mild cases of nearsightedness or farsightedness, surgery LASIK eye procedure radial keratotomy, or RK, is the treatment of choice. This technique surrounds the cornea with a radius similar to the arrangement of plates, causing flattening. RA is gradually supplanted by more advanced techniques.
At one time heaxagonal keratotomy, or ha, was> The laser eye surgery used to correct farsightedness, but its side effects were so strong that it has been virtually eliminated as an option.
Flap Procedures
LASIK actually gets its name from one component procedures of, laser assisted in situ keratomileusis. In this procedure, the surgeon cuts a flap across the epithelium and stroma of the eyes, and uses an excimer laser to remove material that could be responsible for the patientvision problems.
Epi-LASIK is similar to LASIK surgery unless the surgeon cuts the flap does not go deeper than the epithelium. Because this procedure does not require the use of a blade nor alcohol, and payback period is less painful and shorter.
LASEK surgery, while only cuts a flap of the epithelium, loose flap of skin is a little more painful, and requires a longer recovery period, Epi-LASIKsurgery. But it is an ideal choice for those who do not qualify for LASIK eye surgery.
Automated lamellar keratoplasty, and has always been the laser eye surgery performed on or those with hyperopia or myopia, is rapidly becoming obsolete. This procedure, which usually lasts an hour, also creates a flap in the stroma.
Photoablation
Photoreactive keratectomy is the most common eye surgery laser ablation. PRKThis is the phase in the LASEK and LASIK surgery in which the surgeon uses UV radiation to remove damaged tissue or eye useless and reshapes the cornea with an excimer laser. PKA, which requires little time, can be used to treat astigmatism and near and farsightedness.
