What are the most common complications
?
The most common is either over-correction or under-correction, both
of which can be treated. Individual variation is part of any refractive
surgical procedure. While everyone hopes for perfect vision, perfection
is not always the result. Your expectation should be reduced dependence
on glasses and contact lenses, realizing that they may still be needed
for some activities. Dry eyes are also common in the early post-operative
period.
What about severe complications ?
Sight-threatening complications are very rare. There is always a
small risk of infection, scarring, abnormal healing patterns, or
cell growth underneath the corneal flap. This may cause partial
loss of vision and require further medical or surgical treatment.
Will my vision be stable ?
Although vision may fluctuate slightly during the first few days
and also shift slowly for 6 to 12 months, most of the healing is
complete within 3 to 6 months. With nearly a decade of experience
with PRK, we know that the procedure is stable, with no evidence
of late-onset complications. LASIK has been available for about
five years and, from the data collected over this period, also appears
stable.
Is it possible that my vision could be worse than before?
Could my vision gradually decline ?
There is a very slight chance that your vision could be worse. Results
thus far, however, have shown excellent stability after PRK and
LASIK.
Will I be able to wear contact lenses if I still need
them after PRK or LASIK ?
Yes. In most cases, PRK and LASIK do not interfere with the use
of soft contact lenses. Rigid contact lenses can sometimes be used
but the fit may be more difficult. Some patients cannot wear rigid
contact lenses after refractive surgery.
How is PRK or LASIK likely to affect my need to use glasses
or contacts when I get older ?
By middle age, all people need help reading. If your nearsightedness
is permanently eliminated by PRK or LASIK, you may need to start
using reading glasses in your forties.
Will I need to use eye drops ?
Depending on your specific procedure, eye drops may be needed for
anywhere from three days to six months, but not permanently
