Vision correction surgical techniques, tools and procedures have evolved
greatly over the past 25 years. As techniques and procedures have been
fine-tuned, more patients are able to benefit from corrective eye surgery
with better results and fewer risks.
Radial Keratotomy (RK) was the first form of corrective eye surgery. This
procedure evolved into the first
laser eye surgery
, photorefractive keratectomy (PRK). While this is still commonly used,
LASIK eye surgery
is now the most common form of vision correction surgery.
The first corrective eye surgery -- radial keratotomy -- used spoke-like
incisions to flatten the surface of the eye, correcting nearsightedness.
Results of this procedure often created long-term problems for patients,
including glare and night vision problems.
Advances in laser procedures have made radial keratotomy virtually obsolete.
It has been replaced by photorefractive keratectomy and LASIK.
, which is also known as surface ablation or LASEK, uses a laser to remove
specific predetermined amount of tissue from the surface of the eye therefore
reshaping the cornea, without first making a flap in the cornea, as is
done in LASIK. The reshaping allows light rays to bend and focus for improved vision.
LASIK eye surgery
is becoming increasingly more popular as a form of vision correction.
It is used to treat a number of eye conditions, including refractive errors
Not all laser eye surgery is the same. Though different lasers and technology
may be used, traditional LASIK eye surgery corrects vision by creating
a thin flap in the cornea. The flap is folded back and the curvature of
the eye is reshaped. Your vision is dependent on how your eye is shaped.
When the curvature of your eye is reshaped, your eye will refract light
more precisely, allowing you to see more clearly.
Different lasers are used in different procedures, and will produce varying
results. The doctors at Key-Whitman use the Wavelight® Allegretto
Wave® Eye-Q for
and Intralase® blade-free lasers to perform LASIK eye surgery.
o IntraLase -- During the surgery procedure, a flap is created using IntraLase
and it is gently lifted and folded back. The laser reshapes the underlying
corneal tissue by emitting a computer-controlled beam of light that removes
the exact amount of tissue in a matter of seconds. The corneal flap is
then placed back into its original position. Due to the cornea's extraordinary
bonding qualities, no stitches or patches are required.
o OptiLASIK -- This procedure is designed to adapt to the unique curvature
of your eye, reshaping it more closely to the curve of an ideal, natural
eye. As a result, OptiLASIK™ helps preserve the quality of your
vision by ensuring your eyes are reshaped to be able to focus more accurately.
Another option for treating myopia (nearsightedness) is the Vision ICL
(Implantable Collamer® Lens). This is a phakic intraocular lens (IOL)
used during refractive surgery for correcting myopia. The ICL is placed
between the iris and the natural lens. Because the phakic IOL does not
replace the lens, but supplements it like a prescription contact lens,
it is sometimes referred to as an implantable contact lens.
To determine which laser eye surgery procedure is right for you,
schedule a free consultation
The decision to have LASIK is an important one that ultimately only you
can make. It is important to have realistic expectations and that your
decision is based on facts, not hopes or misconceptions. As with any surgery,
there are risks and the possibility of complications. These will be discussed
in the office. While there are many who benefit from vision correction
surgery, there are potential side effects including glare from bright
lights, halos (rings around lights), light sensitivity, night driving
glare, and visual fluctuation. Your individual risks will be discussed
at the time of your consultation. For more information regarding the risks
and benefits associated with the Wavelight® Allegretto Wave® Eye-Q
