PRK
See our schematic QuickTime PRK Movie
PRK is a procedure
that is used to help correct nearsightedness, farsightedness and astigmatism.
First, the epithelium,
the outermost layer of the cornea, is removed gently by
the surgeon. Then, a cool
laser (excimer laser) is directed to the surface of the
cornea to change its shape to correct for the prescription.
Since the epithelium was
removed, an abrasion is formed which typically takes
three to five days to heal. During this time the vision is
blurry. Typically a bandage
contact lens is worn to promote and expedite the healing
of the epithelium. Throughout this healing phase you
may need pain medication.
Once the abrasion
has healed, you should notice an improvement in your
vision. It does take up to three to four months for the full
corrective effect
of PRK
to be seen. You will also be on a tapered
dosage of anti-inflammatory eye drops and moisture drops
for a period of up to 4 months.
