Lasik and Refractive Surgery


Laser in-situ keratomileusis (LASIK), which is sometimes termed laser intrastromal keratomileusis (LASIK), is the most advanced procedure utilizing the excimer laser for correction of refractive errors.

LASIK has become the most successful and popular vision correction procedure in the world. LASIK surgery changes the shape of the cornea permanently. It can drastically decrease the need for glasses or contact lenses for most patients.

The surgery is performed using only topical anesthetics (eye drops). The procedure combines the use of the microkeratome (a delicate surgical instrument) to create a thin protective corneal flap followed by application of the excimer laser beam to the bed of the cornea. The excimer laser removes tissue with minimal thermal damage or scarring to adjacent tissue. The computer guided excimer laser beam accurately reshapes the cornea by removing microscopic layers of the cornea (.25 microns per laser pulse). The corneal flap is then placed back in position and allowed to heal without the need for stitches.

Following a LASIK procedure, most patients are able to resume their normal daily activities the next day. The advantage of LASIK is that there are no raw surfaces left to heal after application of the excimer laser. The normal physiologic layers of the cornea are left intact after the treatment, because the treatment is done beneath the corneal flap.

LASIK surgery improves the focusing power of the cornea. Most patients that have undergone LASIK surgery now enjoy excellent vision without the need for glasses or contact lenses.

Most patients that wear contact lenses or glasses are candidates for LASIK surgery. To find out if you are a candidate for LASIK surgery, you can contact us toll free at 215.639.4500 or email: The initial consultation is free.
