Types of Vision Correction Surgeries
While there are several types of vision correction surgeries available, and we are happy to offer refractive surgery evaluations for LASIK and SMILE.
LASIK
Laser-assisted in situ keratomileusis (LASIK) uses an excimer laser to correct various refractive errors.
During the procedure, the surgeon uses a cutting tool to create a thin flap in the cornea that is lifted up to reveal the corneal tissue underneath. This tissue is reshaped using the excimer laser, and the flap is placed back and left to heal.
LASIK surgery offers certain advantages over other laser surgeries, like less postoperative discomfort, faster healing time, and less chance of corneal haze. Even though LASIK is generally safe, possible complications can arise from the flap created during the procedure. Side effects also include dry eyes, glare, halos, double vision, and under or overcorrection.
SMILE
Small incision lenticule extraction (SMILE) uses a laser to create a contact lens-shaped layer below the surface of the cornea. This layer is removed through a 2 to 3 mm opening, which then heals on its own.
SMILE is a relatively comfortable procedure. It offers a quick recovery time, comes with none of the postoperative restrictions that LASIK does, and avoids LASIK’s flap complications.
PRK
PRK (photorefractive keratectomy) is a type of laser eye surgery that is similar to LASIK, but with some differences.
During PRK surgery, your surgeon creates a small incision in your lens similar to how it’s done during LASIK surgery. However, instead of folding the lens over to reveal your corneal stroma, the entire outer layer is (known as the epithelium) completely removed. From here, the corneal stroma tissue is reshaped to your prescription using an excimer laser.
Your eye will then heal over a couple of days, creating a new lens.
