In any field of medicine or surgery, and especially in eye
care, advances in the understanding of how to better treat to eye conditions,
eye disorders and eye diseases often leads to development of new technology and
procedures for treatment. In the past 25 years it has become commonplace for
medical device manufacturers and pharmaceutical companies to use aggressive
marketing tactics aimed directly at healthcare consumers in order to promote the
rapid adoption and sales of their particular product. Often, these companies
will also use forceful tactics whereby if they create enough "patient demand"
for a particular product, drug or treatment it forces eye surgeons to "offer" it
so that they will not be "left behind" and be perceived as out of date by
patients. Eye care technology has and will continue to emerge at a very rapid
pace. Patients need an objective understanding of alternatives when considering
LASIK so as not to get caught by the "latest and greatest" fad that may be
sweeping LASIK Eye Surgery today.
There are a number of facts that potential LASIK patients
should consider as they are evaluating or are presented with alternatives to
LASIK.
LASIK has Withstood the Test of Time
LASIK was first performed internationally in 1989 and was
introduced to United States LASIK surgeons in about 1990. LASIK underwent Food
and Drug Administration clinical trials to demonstrate safety, efficacy and
predictability in the early 1990's and was FDA approved in 1998 from the data
provided as part of a Pre-market Approval Application (PMA). A PMA requires
extensive safety data and clinical trials. Eye care consumers should not be
completely lulled into feeling confident when a device or procedure is FDA
approved. Most eye care consumers do not realize that there are two completely
different paths to FDA approval that may be required. One, the PMA approval
process, is extensive, time consuming and approximates how a device or procedure
will perform in the "real world" in terms of safety or efficacy. The second
route is called the 510(k) Approval in which a manufacturer must only
demonstrate a limited amount of safety data in order to obtain approval.
Sometimes devices such as surgical instruments can be FDA approved with little
or no clinical trials under the 510(k) process.
What Does this All Mean?
It means that LASIK perfomed with the Excimer Laser has had
extensive FDA monitored clinical testing and data analysis whereas other "new
devices" introduced to perform "better" LASIK or other vision correction
procedures may have not undergone the same level of testing and scrutiny to be
certain that a particular procedure or device was "real world" safe and
effective. This means that these so called 510(k) approved devices may actually
be doing their clinical trials on the first several thousands of patients
treated in order to refine their devices and make them effective. This is why
"latest and greatest" in LASIK surgery is NOT always the best. It has not been
subjected to the scrutiny...yet.
Where Does the Real Scrutiny for LASIK Alternatives
Occur?
With any drug, device or procedure, the true testament to its
safety and efficacy becomes obvious in the "real world", when real eye surgeons,
in real practices using the drug, device or procedure actually use it to meet
the expectations of patient satisfaction. If in the "real world" use of a drug,
device or procedure it is unable to predictably meet or exceed patient
expectations in terms of what it actually delivers without an undue amount of
risks and complications then it will ultimately fail and diminish in use in the
consumer marketplace. So, the real test of safety and efficacy is the
sustainability of a drug, device or procedure such as LASIK over a long period
of time in the consumer healthcare marketplace.
While exact worldwide data are difficult to obtain, we are
able to obtain fairly good LASIK data in the United States because of the
monitoring of laser use through patent license fees paid to Excimer laser
manufacturers. LASIK was FDA approved in 1998 through the more rigorous PMA
process, and conservatively since that time over 5 million LASIK procedures have
been performed. During that period of time, a number of special interest groups
such as various specialties of personal injury and malpractice lawyers and
public relations promoters have demonstrated opportunistic behavior in their
attempts to discredit or damage LASIK surgeons, the LASIK procedure, LASIK
technology and the industry as a whole. While there have been times of LASIK
consumer trepidation, the fact is that LASIK has withstood the test of time and
remains the procedure of choice for the vast majority of patients wishing to
correct nearsightedness, farsightedness or astigmatism for distance vision. That
is not to say that there have not been poor results. The test of time however,
tells us that when LASIK is performed by an experienced LASIK surgeon, in
carefully selected patients, for LASIK patients who have the opportunity to
fully understand the risks, benefits and complications in their particular set
of circumstances, and who have a strong understanding of what their criteria for
success are...LASIK is in fact a safe, effective and predictable method of
correcting vision.
