Adult Strabismus Surgery

When you have LASIK to correct your nearsightedness, farsightedness, or astigmatism, the correction lasts a lifetime. Lasik Laser has changed the shape of your cornea beneath the surface in the stable layer called the stroma, and the layer will retain the new shape indefinitely.

However, this does not mean your vision will never change in your life. There are many causes of vision problems in addition to the shape of the cornea. Best known is the condition age-related presbyopia called, which begins in mid-life. If you have been noticed blurring of the printed book and organized restaurant menus below to see them clearly, and if you are age 40 or older, you notice presbyopia.

Presbyopia all

Presbyopia happens to everyone, if they have LASIK or not. This is not a problem with the shape of the cornea, but a problem with the lens of the eye. The objective is suspended by ligaments behind the iris color and contributes a remarkable capacity to our view. It is called Accommodation.

The lens is spherical and curved front and rear. Its curvature is controlled by two small muscles that surround the muscles called the ciliary. Without our having to do anything consciously, these muscles contract or relax when we go to concentrate near intermediate-to-date and back. They change the curvature of lens, making it steeper for narrow and flat for the distance vision. They accommodate the objective of our vision needs.

The causes of presbyopia are not fully understood, but the currently accepted theory is that time is the hard lens. It becomes less and less able to strongly curved surfaces for near vision, making reading glasses necessary. Another theory suggests that it is the ciliary muscle weakens with age that causes presbyopia.

Whatever the cause, there are several possible treatments for presbyopia and we Monovision LASIK. One eye is corrected for near vision and the other eye is left alone for far vision. The brain learns to adapt to the different data delivery to its center of vision. Treatment can be repeated as presbyopia progresses.

Diseases of the eye that affects vision

The retina may also deteriorate with age. In the center of the retina is a small area called the macula, which gives us our central vision direct that we use for reading or other close focusing. Age-related macular degeneration (AMD), the macula loses some of its cells sensitive to light and obscures the central vision.

However, it is glaucoma, a problem of optic nerve injury. A portion of the optic nerve is damaged where it leaves the retina so that vision less information reaching the brain and we gradually lose the peripheral vision. In most cases, this damage is linked to the pressure inside the eye becomes too high. Glaucoma can not be cured, but can be managed using special eye drops. Untreated, glaucoma causes blindness.

Cataracts also cause blindness if not treated. They are an objective problem, where the lens becomes cloudy, loses its transparency so that the light is blocked from reaching the retina. Cataracts are treated by removing the lens and replace it with an artificial lens. He is also diabetic retinopathy, where the retina can be detached from its blood supply and cause blindness. There are keratoconus, adult strabismus, dry eye syndrome, and many others.

In short, the vision can be affected in many ways with age, regardless of the fact that we have had LASIK. But you definitely relieves LASIK for myopia, hyperopia and astigmatism, which gives you a clear picture until at least.
