LASIK - A Detailed Explanation
By Peter Spartalis
Are you one of the millions of Americans with impaired eye sight?
Are you looking for a fast, effective, and SAFE way to correct your vision?
LASIK eye surgery could be the answer for you. Before even considering laser eye surgery you should thoroughly read all available information.
History
Thousands have to deal with the hassle of wearing their glasses, others to try to avoid glasses use contacts which are a large hassle of their own. A revolutionary technology called LASIK eye surgery has the potential to eliminate the need for older forms of vision assistance. LASIK stands for Laser-Assisted in Situ Keratomileusis. The development of laser eye surgery began decades ago but it has just recently been perfected to the point of being able to use it to correct common eye problems.
Lasik Vs Lasek - Spelling Error Or Important Distinction In Laser Eye Surgery?
LASIK and LASEK are similar forms of laser eye surgery used to correct nearsightedness, farsightedness, astigmatism, and (with special conditions) presbyopia. LASIK is an acronym for “Laser-Assisted In Situ Keratomileusis,” while LASEK stands for “Laser Assisted Sub-Epithelial Keratomileusis.” The reference to “sub-epithelial” in the second acronym provides a clue to the differences between these two surgeries.
Epithelium
In LASEK, the epithelium, or thinnest outer layer of the cornea, is cut not with the microkeratome cutting blade used in LASIK, but with a finer tool called a trephine. Both surgeries create a covering for the cornea, which can be put back in place at the end of the procedure. Because it uses a thinner cutting instrument, the LASEK procedure can create this covering from just the epithelium, whereas LASIK involves cutting into deeper layers of the cornea.
