Forty-two eyes of 23 patients (12 female, 11 male) in the
PRK group and 42 eyes of 22 patients (12 female, 10 male) in the SMILE group were evaluated retrospectively.
William D K (5) in a series of
PRK in high myopia, treated 88 eyes with SE refractive correction ranging from -12 to -22 with 12 months follow up.
The technological advances and new production techniques used by Leuze electronic in the build of the new
PRK 3B offers maximum functional reliability and handling convenience coupled with an optimum cost-to-performance ratio.
RK and
PRK surgery may result in overcorrection, which renders you farsighted, or undercorrection, which leaves you nearsighted.
The surgeon uses an optical zone marker 1 mm larger (approximately 7mm in diameter to accommodate a 6mm laser optical zone) than the desired optical
PRK zone.
That is why ophthalmologists like Pannu - and major universities - have spent upward of $600,000 buying excimer lasers to perform LASIK and
PRK.
This combines
PRK with an older surgical procedure known as keratomileusis.
Milne noted that his results were a "huge improvement" over his previous experience with
PRK, in which he also used the Durrie Technique.
Related procedures such as LASEK, Epi-LASIK,
PRK and custom LASIK are described, along with procedures such as implants and conductive keratoplasty.
Epi-LASIK combines the most desirable features of today's popular refractive techniques -- LASIK and
PRK.
In addition to LASIK, the section includes detailed information on refractive procedures such as custom LASIK, LASEK,
PRK, CK and prescription inserts.
Approximately 30 subjects undergoing bilateral myopic
PRK will participate in the trial.
