to Expect Before, During, & After CRT
The basic purpose of FDA Approved corneal refractive therapy is to improve visual
function. For many, this is a safe, non-surgical approach or
improving and restoring vision.
On the first day of
your procedure you should arrive at the office as rested and relaxed
as possible. Don't wear make-up for your initial fitting. It may
interfere with the cleanliness of the procedure. Expect this visit
to last approximately one hour.
The new contact lenses will be placed on your eyes. You will have an
adaptation period of 10 to 20 minutes. During this time, you will
feel a slight awareness of the lens on the lid. You will be
instructed in the proper method of lens insertion and removal and
the hygiene associated with the lenses. You will be given all the
solution and instructions necessary to handle this at home.
We will train you until you have demonstrated proficiency with
insertion, removal, and centering of your lenses. We will then
discuss your lens-wearing schedule with you. To ensure the best
possible results, it is essential that the wearing schedule be
followed closely. Your exact wearing schedule depends on the
severity of your myopia and your lens-wearing success.
During night wear, the eyelid covers the lens. This results in very
little lens movement. You likely will have very little feeling of
the lenses the first night. The lenses are highly oxygen-permeable,
so the cornea will not be deprived of oxygen even when the lenses
are worn while sleeping. After the initial session of contact
fitting, you will be scheduled for an appointment one to two days
later. This is a very important visit since the cornea and resulting
vision are rapidly improving at this stage.
A follow-up exam will include an exam while wearing the lens, which
includes an evaluation of the lens fit and visual acuity, and an
exam with the lens removed. This includes measuring unaided visual
acuity, corneal curvature measurements with keratometry, and corneal
topography. The objective and subjective refraction determines your
new vision correction, and biomicroscopy evaluates the health of the
eye. A refitting of new accelerated contact lenses as necessary or
possible contact lens modifications may take place.
Follow-up appointments are usually scheduled for two-weeks,
one-month, and six-months, but can vary depending on your
unique requirements. When it is determined that your maximum desired
results have been achieved, a retainer lens program will be
arranged. Retainer lens exams will be performed every year. Retainer
lens wearing will range from every night to wearing the lenses only
one night per week.
