Your eye care practitioner can help you decide, but here are some general guidelines.

Laser vision correction should not be performed if:

• Glaucoma, infection, cataracts, severe dry eye or any other condition that would affect postoperative healing.
• Age 18 or younger(with so
  me exceptions).
• Unstable vision before surgery.
• If you’repregnant or nursing, your hormonal levels can affect the shape of your eye. You’ll need to wait until your hormones are back to normal levels.
• Degenerative or autoimmune disease, since this would affect healing.
• Thin cornea (with some exceptions)

Cataract surgery should not be performed if:

• The patient does not desire surgery
• Glasses or other visual aids provide functional vision satisfactory to the patient
• The patient’s quality of life is not compromised
• The patient is medically unfit
• The patient has concomitant disease where functional improvement is unlikely
