Trans PRK (
BLADELESS & CUTFREE TREATMENT)
Our team and I have worked together to provide you with the most
up-to-date and reliable information on TransPRK from various websites
and other readings. TransPRK is an all-laser technique for treating
short-sightedness (myopia), astigmatism and youthful long-sightedness (hyperopia).
This method of treating refractive errors is gaining popularity because
of its elegance and simplicity. Treatment is done without touching the
cornea and the accuracy of treatment is excellent. It requires no flap
creation and therefore, avoids all the complications related to the flap
and is superior to Epi-LASIK because there is no blade necessary to
remove the superficial surface layer of the cornea (epithelium). The
epithelium is gently vaporized by the laser and only a minimal amount of
corneal tissue is removed, leaving the cornea stronger than with other
procedures. This is an all-laser technique for treating
short-sightedness (myopia), astigmatism and youthful long-sightedness (hyperopia).
TransPRK is a no touch, no blade technique that has all the benefits of
Epi-LASIK with none of the risks. This is ideal for active sportsmen and
people working in jobs that have high risk of injury to the eye.
By reading our website, we hope you learn more about TransPRK and
whether it is suitable for you!

PRK and
LASEK (Advanced Surface Ablation)
PRK (photo-refractive keratectomy) and LASEK (laser epithelial
keratomileusis) are both advanced surface ablation procedures used to
correct vision by using the excimer laser to shape the surface of the
cornea, rather than the interior. PRK was the first FDA-approved procedure
changing the curvature of the cornea with the excimer
laser. Safety and clinical data on the first PRK surgeries date back
to 1990.
PRK and LASEK use the same excimer laser as LASIK and the same
Wavefront mapping, but the procedures are
performed on the surface rather than inside the cornea. With PRK, the
epithelium (top skin layer) of the cornea is actually removed; with LASEK,
the epithelium is moved aside and then replaced after surgery. In each
case, the laser is then used on the surface of the corneal tissue only.
To assist the healing process after PRK and LASEK, a clear bandage contact
lens is placed over the cornea during the 3-5 days needed for the
epithelium to re-grow. Additionally, patients are normally placed on a
regimen of steroid eye drops for a three to six month period, requiring
monitoring by their doctor on a weekly or monthly basis. Like LASIK, PRK
and LASEK only take about five minutes per eye, and the surgery itself is
painless. There is typically more discomfort during the healing process
after advanced surface ablation procedures, and it takes a bit more time
for the patient to see clearly, but in the end, outcomes for LASIK, PRK,
and LASEK are the same.
There are some medical conditions that may make either PRK or LASEK more
suitable than LASIK. LASEK, for example, is used mostly for people with
thin corneas since LASIK requires more corneal tissue to be successful.
PRK is often preferred for patients who may be susceptible to dry eyes
since dry eyes are more often a complication of LASIK.
