LASIK
What is LASIK?
Lasik stands for laser in situ keratomileusis.
It is a form of laser surgery that is capable of
correcting nearsightedness, farsightedness and
astigmatism. The procedure uses a Computer
controlled Excimer Laser to reshape the cornea
to correct the vision. The laser reshaping is
done under a protective flap of tissue to
promote a very rapid recovery of vision and
minimize discomfort.
What are the criteria for patient selection in
LASIK surgery?
Patient should
- Be above 18 years of age
- Have stable refraction for 6 months
Upto what power of refractive error (glasses
number) can be corrected by LASIK?
LASIK can correct :
| Myopia from |
-1.00 to -12.00D |
| Hypermetropia from |
+1.00 to +6.00D |
| Astigmatism from |
-1.00 to -6.00D |
| |
+1.00 to +6.00D |
How long does the procedure take?
The LASIK procedure takes about 10 minutes
per eye.
Is the procedure painful?
No! Anaesthetic drops usually allow the
operation to be performed without pain.
What are the restrictions following
surgery?
The usual restrictions after surgery are that
a protective shield should be worn to bed for
the first week. Swimming is not advisable for
one week after surgery, although bathing and
showering is fine. No eye make up should be
applied for 7 days. All other activities may be
resumed on the first day following surgery.
Can the procedure be performed on both
eyes at once?
Yes! Most patients choose this option as it
is far more convenient.
Are glasses required even after the
procedure?
This will depend on a number of factors,
including the refractive error, the visual
needs, and even your personality. It is
important to understand that LASIK does not
eliminate the need for reading glasses as one
grows older.
What are the usual side effects?
The patient's vision will fluctuate during
the few days following surgery. The patient may
notice some glare around lights at night. There
may be a feeling of dryness in the eyes. Rarely
a patient may have persistence of one or more of
these effects. These effects are usually more
during the first two weeks after surgery and
then slowly disappear.
What are the complications of the surgery?
Like any surgical procedure, LASIK carries
some risk of complications, although they are
not vision threatening.
When can the patient get back to work?
Usually after 3 days of the surgery.
