Before Lasik surgery, you need to know what to expect. The first day of your procedure will be the most important, but you may be nervous and have a few questions. Your eye doctor will first perform a thorough eye examination. They will measure the thickness and shape of your cornea, as well as your pupil size and any other conditions affecting your vision. They will also check your tear film, which is a protective film over your eyes. If your tears are poor quality, your eye doctor may recommend some precautionary treatment before LASIK. Your ophthalmologist will also use a corneal topographer to assess the curvature of the front surface of your cornea. The procedure will require two or three visits. click for more info on this topic.
For some people, Lasik is not a good idea. Hyperopia is a condition that affects the retina and is harder to correct than myopia. Patients with hyperopia have problems seeing objects near them, but can see them clearly when they are far away. The main benefit of LASIK is that it will improve your vision and improve your quality of life. But it is not for everyone. Before having the procedure, you should consult your doctor and discuss your expectations.
People with astigmatism and hyperopia will probably need some sort of refractive surgery. Both conditions result in poor vision. Neither condition can be corrected with glasses or contacts. If you think you may need the surgery, you may want to try monovision. This technique involves leaving one eye slightly nearsighted and adjusting it for distance vision. It is important to note that monovision is not for everyone. You should try it with contact lenses first.
After the procedure, you will be required to wear a special contact lens bandage for one week. The flap is healing slower with LASEK, so it will take at least a week for it to fully heal. If your vision is cloudy after the operation, you may have an uncomfortable vision for several months. You may also feel like something is in your eye. Regardless of which option you choose, you should have the procedure done for the best outcome.
Another risk is astigmatism. The surgery is not a cure-all. The risk is too high to be considered an acceptable outcome for all patients. A doctor must carefully evaluate your eyes before performing the procedure. Afterwards, you may need to wear glasses or contact lenses for a few weeks. If you have keratoconus, your vision may be worse after LASIK. The underlying condition can cause glaucoma or a variety of other vision problems.
If you’re over 40, you may have presbyopia, which is a condition that makes the lens of the eye stiff and impairs close-up vision. However, presbyopia can be treated with either procedure. There are some other options for you, but LASIK is often the best choice. If you have a high prescription or thin cornea, you may be a candidate for photorefractive keratectomy.
