LASIK vs. PRK

Photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) are laser surgery techniques used to help improve vision by modifying the cornea. They are more alike than they are different, the difference being primarily in how the eyes are prepared for surgery, which affects the length of recovery time.

LASIK Procedure

• A flap is created in the cornea
• An excimer laser is used to reshape the corneal tissues
• The flap is put back in place to heal with the rest of the eye’s tissues 

LASIK Recovery

• Most people see more clearly within a day following the procedure
• Lubricating or medicated eye drops will be prescribed to take care of any irritation
• The complete healing process only lasts a few days

PRK Procedure

• Part of the top layer of the cornea is removed
• An excimer laser is used to reshape the corneal tissue layers
• A “bandage” like a soft contact is placed on the cornea to protect the eye as the tissues heal

 PRK Recovery

• Vision will be a little blurry as the eyes heal, before the bandage is removed
• Lubricating or medicated eye drops will be prescribed to keep the eyes moist and relieve any discomfort
• The complete healing process may take up to a month, with vision getting better each day
