After the Operation

• LASIK surgery is an outpatient operation, so immediately after the surgery, it is not uncommon for eyes to burn, become watery or feel itchy. Also, vision will often be blurry right after the procedure, so it is recommended that the patient be driven home. Vision is usually good enough after the procedure for unassisted walking but not driving.
  
  

Care at Home

• The surgeon or a health-care provider will give the patient detailed eye-care instructions after the surgery. Eye drops and eye shields are often provided to help prevent eye irritation and damage. According to MayoClinic.com, the chance of infection can be greatly reduced if patients wait several weeks before swimming or using hot tubs, in addition to using the eye drops provided. It is also beneficial to keep hands clean and avoid rubbing the eyes.
  
  

Vision

• Vision will not be crystal clear after the surgery, but it should recover within 24 to 48 hours. Even then, it will not be perfect, and according to MayoClinic.com, it might take two or three months before the eyes completely heal and vision becomes stabilized. Many patients have follow-up appointments a day or so after the surgery to ensure that there are no complications. One vision problem known to occur after LASIK surgery is trouble seeing at night, which is characterized by glare, double vision and halos surrounding bright lights.
  
  

Under-corrections and Over-corrections

• Under-corrections and over-corrections occur when the laser removes too little or too much corneal tissue, resulting in eyesight that is not any clearer or not clear enough. Under-corrections can be fixed by more surgery, but over-corrections are much more complicated to remedy.
  
  

Astigmatism

• Astigmatism can result from LASIK surgery when an uneven amount of tissue is removed. This can happen if the eye is not stable enough during surgery, and it might require more surgery to correct.
  
  

Dry Eyes

• Eyes might feel unusually dry for the about the first months after LASIK surgery. Although eye drops are often recommended, according to MayoClinic.com, there is also a procedure that can help that prevents tears from draining from the eyes' surfaces.
  
  

Flap Problems

• During LASIK surgery, a flap in the cornea is made using either a laser or a tiny blade to allow the surgeon access to the cornea tissue. Sometimes this flap becomes infected, or the tissue underneath grows abnormally.
