Refractive surgery is one of the most common elective procedures done today. It is an out-patient procedure that can correct several vision issues such as nearsightedness or farsightedness. In the most common form, the doctor changes the shape of the cornea using a small laser. These changes are subtle and take some time to heal. However, any changes to the cornea affect the way light passes through.
In many cases, surgery patients experience mild double vision as they recover from the surgery. These issues normally resolve themselves within ninety days of the procedure. If a patient still experiences vision issues six months after the surgery, the doctor may recommend a second corrective procedure.
