Introducing the Latest in Laser Vision Correction: SMILE, Lasik, PRK, and their differences.

SMILE – Laser Vision Correction


SMILE! There’s a new laser vision correction technology option available – only at Eyes of York! Eyes of York will be the first practice in Pennsylvania to be offering a full range of laser vision correction options with the addition of SMILE.

Laser Vision Correction has been helping people reduce or eliminate their need for reading glasses and/or contacts for over 25 years. Today, we want to tell you about the newest in laser vision correction technology that is coming to our practice – SMILE! Understanding the differences between the procedures will help you in understanding your options when it comes to laser vision correction.

PRK or Photorefractive Keratectomy was developed in the early 1980’s where the excimer laser is used precisely to reshape the cornea without first creating a corneal flap. PRK may be safer for some people including those with thin or irregular corneal tissue or those who are high risk for eye injury. The technique involves gently removing the outermost layer of the cornea, which will require 3 to 4 days of healing.

Researchers refined laser vision correction with LASIK in the early 1990’s. Instead of working on top of the corneal surface, LASIK uses a blade or femto laser to create a thin flap in the cornea, reconstruct the tissue underneath, and replace the flap like a natural bandage. The flap allowed for less discomfort and a faster recovery.

SMILE is the first major innovation in laser vision correction since LASIK. Instead of creating a flap, a small 6mm opening is made. The laser creates a thin, contact lens-shaped layer beneath the surface of the eye which is then removed through the small opening that was created. Removing this thin layer, the cornea is gently reshaped and the patient’s vision is sharpened, correcting the refractive error. Since a smaller incision is made, patients experience less dry eye and redness post-operatively with a quick recovery period.



Visual outcomes with SMILE are highly predictable. More than 750,000 SMILE procedures have been performed worldwide with consistent results.
