What is LASIK?
LASIK is an outpatient surgical procedure
that uses a cool laser beam to gently reshape the surface of the cornea. This causes little or no discomfort and improves
vision. The beam gently pulses to remove a microscopic amount of tissue, allowing images to be more sharply focused on the
retina.
What are the differences between LASIK and PRK?
While LASIK and PRK are both effective
laser procedures, most doctors and patients prefer LASIK. This procedure offers the following advantages:
In addition, LASIK can be used to treat a much wider range of vision disorders.
Since with LASIK the surface of the cornea (epithelium) is preserved, LASIK patients see better the day following their procedure. PRK patients may require several days to weeks to achieve clear vision.
Am I a good candidate for LASIK?
Yes, if you’re at least 18 years old, in good general health, have good eye health with stable vision for the past year
and no diseases such as cataracts. Laser surgery is used to treat a broad range of nearsightedness, astigmatism and farsightedness.
In most cases, even patients with severe degrees of nearsightedness, astigmatism and farsightedness can be treated. Good candidates
have realistic expectations.
What kind of results can I expect?
While laser vision correction
has proven overwhelmingly successful, how well and how quickly your vision improves depends on how well you heal and the degree
of correction required. Although patients can’t be assured 20/20 vision, most LASIK patients with mild to moderate prescriptions
do achieve 20/20 vision or are within one line of their best corrected vision. This means they no longer need glasses or contacts
to drive, play sports, watch movies and TV, and can participate in careers requiring excellent vision such as being a pilot,
police officer or firefighter.
Will the procedure hurt?
The LASIK procedure causes little or no
discomfort and no needles are used. Instead, Dr. Boothe uses anesthetic drops to numb the eye just before surgery begins.
After a LASIK procedure, the patient may feel a slight gritty sensation for a few hours, but should be quite comfortable after
taking a short nap. Dr. Boothe can prescribe pain medication to alleviate any discomfort during recovery.
How
well will I see after the LASIK procedure?
Results vary with each individual. In a recent study, 98 percent
of patients treated for nearsightedness and/or astigmatism with the VISX STAR Excimer Laser System saw well enough to pass
a driving test without glasses almost immediately. The patient’s vision should be improved immediately after treatment. Some
patients may experience small vision changes during the first several months, which is a normal occurrence as the cornea reaches
its stable state. After the patient’s eyes have stabilized, Dr. Boothe will evaluate the results. If they are less than optimal,
the patient may be eligible for an enhancement at no additional charge within three to five months of the initial procedure.
How
soon can I return to work?
Some people go back the day after treatment. Two days are suggested. Most of Dr.
Boothe’s surgeries are performed on Friday so that patients can return to work on Monday.
Are there any risks
or side effects with LASIK?
Yes, as with any surgery, laser vision correction involves a degree of risk. Dr.
Boothe gives patients the information regarding those risks and answers any questions that they may have. Results of clinical
studies indicate that the chances of having a vision-reducing complication are less than 1 percent. There have been no reported
cases of blindness resulting from LASIK.
Is it expensive?
Compared to the cost of glasses, contact
lenses and lens care over the course of 10 years, LASIK is a cost-effective alternative. Patients have clear, natural vision
with reduced (or eliminated) dependence on glasses and contacts. While some medical plans may cover the cost, most still consider
this an elective treatment and therefore do not pay for the procedure.
