Considering LASIK? Expect your stay at the laser eye
surgery center to be approximately 2 hours. However, the actual laser
treatment might take only about 7 to 10 minutes per eye. Though quite
complex a procedure, its expedited nature renders it a simplistic feel,
at least superficially. LASIK is a relatively painless procedure as
opposed to other surgical techniques.
Even though it’s a surgery,
LASIK is performed with the patient awake and functional. However, the
eye surgeon typically administers a mild sedative (for instance Valium)
and anesthetic eye drops. The complete 7 to 10 minute process can be
broken down into two major steps. The initial step involves the
creation of a flap of corneal tissue. This is accomplished with a
microkeratome (a surgical blade), or a femtosecond laser. A hinge is
left at one end of the flap and the flap is folded back to reveal the
stroma (the middle section of the cornea).
The second step of the
procedure employs a high precision laser, an excimer laser, to reshape
the cornea. The excimer laser is a “cool laser”, that is, it achieves
precise ablation without heating or damaging the surrounding tissue.
After carving the cornea in the desired manner thereby imparting the
desired refraction to it, the flap is repositioned. The flap remains
placed by natural adhesion and aids in the healing of the cornea.
Much
like the procedure itself, the visual recovery is also rapid in case of
LASIK. Since the ablation is performed in the stroma, under the corneal
flap, the cornea does not register the fact that it has been operated.
As a result, the wound response is muted, and that is the reason for a
hasty recovery after LASIK.
On the whole, LASIK is a fairly
innocuous procedure, without the need for hospitalization. Though the
patient might experience blurry vision immediately after surgery, the
visual acuity is restored within a day or two, and the patient may
resume his/her daily chores with ease. In fact, the preparation towards
the procedure (the preoperative examination) may take up more time
relative to the procedure itself. Finally, the results achieved through
this 7 to 10 minute LASIK procedure are certainly worth the endeavor.
