Patients should understand that
having expectations that are realistic for their particular
case is most important to their ultimate satisfaction with
the results of the procedure. While we provide general statistics below, it is important
for patients to talk with the doctor and review their expectations
prior to making a final decision.
Expectation
While we provide information regarding the overall expectations
for the surgery, we understand that there are specific questions
that arise in the first few weeks following the surgery.
Speed of Visual Recovery
Patients should understand that, while fast visual recovery
characterizes the operation, it can take several months before
some patients achieve their final vision after LASIK. Several
studies demonstrate that the vision of a number of patients
continued to improve up to six months post-operatively.
Crispness of Vision
Patients need to understand that, for many people, 20/20
vision after LASIK can be different from 20/20 vision with
contact lenses before LASIK, especially gas permeable contact
lenses. The images seen through eyes treated by LASIK are
often described as not being as "crisp" as those seen through
glasses. This condition, referred to in ophthalmic literature
as "loss of contrast sensitivity," will not affect your acuity
as it is measured on an eye chart, but the visual experience
is different enough that a new term has been coined: LASIK
20/20. While the majority of patients do adjust to this change
following LASIK, patients who perform fine detail work (artists,
architects, draftsmen) should be sure to carefully weigh the
benefits LASIK can afford against the potential loss of contrast
sensitivity.
Results
This data reflects the results of a large range of myopia
(-1.00 to -14.00) and astigmatism (1.00-4.00). The lower the degree of nearightedness and astigmatism, the
greater chance to get 20/20 or close to it.
The Excimer laser is an extremely accurate tool. However,
with some patients, particularly the ones with higher range
of myopia and astigmatism (-10.00 and above), a minor correction
may still be needed to achieve the best and most comfortable
vision possible. Under these circumstances, an enhancement
may be performed. This occurs with approximately 6-15% of
patients. |
