Lasik (laser In Situ Keratomileusis)


Laser in situ keratomileusis, or LASIK, is eye surgery to improve your vision. One or both eyes may be done. You may be able to see clearly without glasses or contact lenses after LASIK.



  • Medicines can help decrease pain or inflammation, or keep your eyes moist. You may also need medicine to prevent an infection caused by bacteria.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him or her if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

You may need to return to have your eyes checked. Write down your questions so you remember to ask them during your visits.

What to expect after LASIK:

Your eyes may feel gritty or itchy the first few days. They may be sensitive to light, watery, or painful. You may have redness on the whites of your eye. Your vision may seem hazy. You may see halos or glare around lights. It may be hard to see at night. These problems usually improve as time passes.


  • Do not rub your eyes for at least 3 months. Rubbing your eyes can move or damage your corneal flaps.
  • Protect your eyes. Wear your eye shields at night during the first week after surgery. Wear safety glasses when you do activities that may cause damage to your eyes. Wear sunglasses when you are outside during the day.
  • Do not bathe for 24 hours after your surgery. Try not to get water, soap, or shampoo in your eyes for at least 2 weeks.
  • Wear glasses if you need them while your eyes heal. Your vision may continue to change for up to 4 weeks before you can stop wearing glasses. Do not wear eye makeup for at least 2 weeks.
  • Ask when you can return to your usual activities. You may need to wait up to 1 week before you start to exercise. Avoid strenuous activity for up to 4 weeks. Do not use swimming pools, hot tubs, or saunas for 2 weeks. Do not scuba dive or sky dive for 1 month. Do not drive until your vision becomes clear.

Contact your healthcare provider if:

  • You have a fever.
  • Your eyes are red, swollen, and draining pus.
  • You have eye pain that does not go away, even with treatment.
  • Your vision becomes worse all of a sudden.
  • You have questions or concerns about your condition or care.

Seek care immediately or call 911 if:

  • You cannot see at all.
