Are you tired of wiping off the fog or sweat off your
eyeglass lenses? Or the tedious but necessary time spent cleaning your contact
lenses? do you suffer from any of these conditions? Myopia, commonly called
nearsightedness, or hyperopia, farsightedness, and astigmatism. If so, then yes,
there’s a safe laser eye surgery procedure for you.
Today’s medical lasers are more sophisticated and it's complemented by
surgical techniques that are less invasive - there is a safe laser eye surgery
procedure for you.
Let’s examine three procedures to help you decide which procedure the safe
laser eye surgery for your eyes.
PRK is the acronym for Photo Refractive Keratectomy and was invented, and
practiced since the early 80s’. However, it got the FDA nod only in 1995. The
entire procedure is performed using an excimer laser, and reshaping takes place
by the removal of surface cells on the cornea. Healing time takes longer, a
month and gaining improved vision is also gradual. A majority of patients don’t
feel much pain during the operation.
LASIK stands for Laser-Assisted In Situ Keratomileusis and is the most
popular of all three laser eye procedure, because the operation is fast and
healing takes place in a day or two and improved eyesight is immediate. Approved
by FDA in 1998, it’s relatively new, but the medical data on it is promising.
Here the surgeon creates a flap under the cornea and then reshapes it by cutting
out corneal tissue.
CK stands for Conductive Keratoplasty. The surgeon operates by using a probe
that is thinner than a strand of human hair. The probe utilizes radiofrequency (RF)
energy and is applied in a circular pattern on the outer cornea to shrink small
areas of corneal tissue. The circular shrinkage pattern is creates a
constrictive band (like the tightening of a belt), increasing the overall
curvature of the cornea. The procedure uses no knives, or laser or other
surgical instrument inserted in to the eye. Healing is faster and there are
fewer complications. FDA approved the procedure in 2002 and it is temporary
pending more medical data on the procedure. However, available information shows
that there is no regression for the patients and the operation only takes 15
minutes to do. By any standard, this is also a safe laser eye surgery procedure
you can consider.
So there you have it, a brief comparison of surgical techniques. It’s up to
you to decide which of these is the safe laser eye surgery procedure is for you.
In the end, the skills and the experience of your eye surgeon accounts for a
large part of the success of the surgical technique.
