Vision problems
The curvature of the cornea and the lens are important factors in determining how well light is focused on the retina. However, not every cornea is shaped in a way that provides the best visual focus. The following sections give an overview of the most common vision problems.
Myopia (nearsightedness) |
Hyperopia (farsightedness) |
Astigmatism |
Other conditions |
Important patient information
Ziemer FEMTO LDV lasers are prescription medical devices that can only be used by accredited eye care professionals for LASIK and other approved surgical procedures. Only a trained eye care professional can determine if a FEMTO LDV laser procedure is appropriate for your condition. Talk to your doctor if you have a family history of keratoconus, glaucoma, other eye-related diseases, diabetes, a history of herpes simplex or herpes zoster keratitis, significant dry eye, severe allergies or have had changes in your vision over the past year.
The LASIK (laser-assisted in situ keratomileusis) procedure causes permanent changes to the cornea as a therapy for myopia, hyperopia or other diseases where the cornea is not an optimal shape. You should not have LASIK if you have autoimmune or an immunodeficiency disease, if you are pregnant or nursing, show signs of corneal thinning, or take medications with eye-related side effects, such as Isotretinoin (Accutane®) for acne treatment or Amiodarone hydrochloride (Cordarone®) for cardiac arrhythmia. LASIK is for adults whose vision has stabilized.
Risks associated with the LASIK procedure include: dry eye syndrome, the possible need for glasses or contact lenses after surgery, visual symptoms including halos, glare, starbursts, double vision, other visual irregularities or possible loss of vision. Results may vary for each individual patient.
