A successful outcome for LASIK eye surgery largely depends on the
patient being a good candidate for the surgery. If someone is not a good
candidate for LASIK eye surgery, there is a greater risk for
complications and the candidate may be less likely to experience the
positive results of LASIK. The best way to determine if someone is a
good candidate for LASIK surgery is to talk to a doctor who specializes
in the LASIK procedure. There are a few risk factors that will
disqualify someone from having LASIK surgery.
Anyone under the age of 18 years of age will most likely be
disqualified from having LASIK eye surgery. In order to be a good
candidate for LASIK surgery someone must have a refractive error and a
glasses or contact lens prescription that has been stable for at least
one year. Typically those younger than 18 years old do not have a stable
enough prescription because refractive errors rarely stabilize before
adulthood.
Thin corneas are another common factor that may disqualify someone
from being a good LASIK candidate. A LASIK doctor can measure corneal
thickness and determine if a patient has adequate corneal thickness for
LASIK surgery. Performing LASIK on thin corneas could result in
complications. In some cases, those with thin corneas may find that PRK
is a better option in place of LASIK.
A LASIK doctor will also measure a patient’s pupil size. Large
pupils can interfere with LASIK results and will therefore disqualify a
patient from having LASIK surgery. A patient with large pupils may
experience side-effects after their LASIK eye surgery. These
side-effects can include glare, halos, starbursts or even double vision.
These effects can be debilitating, preventing patients from driving at
night or in bad weather conditions.
Corneal scarring may also disqualify someone from having LASIK
surgery. Scarring from an eye injury or previous eye surgery can prevent
someone from being a good candidate for LASIK. A LASIK doctor can
discover corneal scarring during the Pre-Op eye exam.
Other factors that may affect a patient’s eligibility to
successfully undergo LASIK can include cataracts, glaucoma, retinal
detachment, dry eyes, keratoconus, ocular herpes, and diabetic
retinopathy. Certain medical conditions, such as autoimmune diseases,
immunodeficiency states, diabetes and some medications may further
interfer with the healing process after LASIK. The presence of any of
these conditions can and may disqualify a patient from LASIK surgery.
In addition to the medical conditions listed above, women who are
pregnant, nursing or wish to become pregnant should wait to have LASIK
surgery. Hormonal changes that are associated with pregnancy, childbirth
and nursing can affect visual acuteness and will disqualify someone
from being a candidate for LASIK eye surgery.
To receive the best results from LASIK a doctor must determine that a
patient is a good candidate prior to the procedure. In some cases, when
one or more of the conditions above are present, a doctor is needed to
determine that a patient is not a good candidate for LASIK and not allow
them to have the surgery. In these cases it is best to listen to the
doctor’s recommendation.
