New York VISX Lasik Surgeon
Robbins was one of the U.S. physicians chosen by VISX to assist in the early clinical trials for the excimer
laser. Initial protocols called for surface treatment
of the eye with the laser in a procedure known as PRK.
The outermost cells of the cornea are constantly being
regenerated and replaced, much like our outer skin.
For any laser refractive procedure to have a permanent
effect, the treatment must be applied beneath the outer
skin of the eye. PRK involved the mechanical removal
of this outer skin (epithelium). This outer layer then
regenerated over a period of weeks to months.
the very good results achieved with PRK, physicians
and patients were dissatisfied with the relatively slow
visual recovery and initial discomfort. An additional
problem was the development of corneal haze, particularly
in individuals with stronger prescriptions. Corneal
haze developed in a small percentage of cases (1-2%)
and could potentially result in a loss of Best Corrected
Visual Acuity (BCVA).
contrast, LASIK requires the surgeon to create a superficial
flap composed of the outer cells of the eye (epithelium)
along with some of the underlying tissue (stroma). This
flap is created with a device called a microkeratome.
The flap is left attached to the eye with a hinge placed
either nasally or superiorly. In most instances the
flap is 160 microns in thickness. The flap must be of
uniform thickness and an appropriate size for the desired
treatment. By preserving the outer skin of the eye LASIK patients experience less discomfort and a quicker visual
recovery. The incidence of haze or scarring is dramatically
lower with LASIK. At the end of the procedure the outer
skin is placed back over the treatment area. It is extremely
important that this outer skin layer be placed back
on to its original position without folds or striae.
Any irregularity of the outer corneal surface can result
in a loss of BCVA.
1997 Dr. Robbins was one of the first surgeons in Upstate NY to offer the LASIK option . At that point in time,
LASIK was an "Off-label" use of the excimer
laser. Initially this procedure was recommended for
individuals with stronger prescriptions who were at
higher risk for developing haze following PRK. As the
technology improved and the superiority of the procedure
over PRK became evident, the indication for LASIK was
broadened to include most refractive errors. Currently
the LADARVISION system has received FDA approval for
LASIK treatment of nearsightedness, farsightedness and
