Your eyes are made up of several different layers, and each layer is important to creating a complete picture of the world around you. The eye acts in the same way a lens behaves. When you look at something close up, the lens will flatten to focus on the nearby item, and when you look at something far away, the lens will flex so that you can focus far away. The inability of the eye to focus properly is called astigmatism. If you are nearsighted, your eyes do not focus well on distant items. The reverse is true for farsightedness. Either one can be something of a burden, and they’re both corrected with corrective lenses that mimic the way in which your eye is supposed to flex, in order to more properly refract light. However, if you want to ditch the glasses and the contact lenses, you will need to undergo corrective surgery.
While lasers lights can be a little frightening, the technology for corrective surgery has been around since at least the 1960s. The old models of corrective surgery were somewhat painful and had very long recovery times. Now, you can recover in a matter of days from LASIK in San Antonio. The process is pretty simple and can be completed within a few hours. You simply need to make sure that you call a good surgeon who specialises in the new techniques.
There are a few steps to the process. First, you’ll need to stop wearing contacts if you do wear contacts. The contacts often encourage the eye to reshape itself to help you to see better. They also affect the natural ecosystem of your eyes; when you’re going to into surgery you don’t want the eye to be in anything but its natural state. So, you’ll need to stop wearing contacts sometime between one month and one week before your surgery. After that, you’ll head to the doctor, at which time the doctor will begin the surgery.
Laser vision surgery happens in basically three steps. First, the doctor will use a sophisticated machine to puncture the outer layer of your cornea. Typically, this is done by making dozens of tiny holes in the surface of the cornea and peeling back a flap of the cornea. This reveals the corneal stroma, the middle layer of the cornea. The laser is then used to cut and reshape the middle layer of the cornea. Once it has been reshaped so that it can properly focus on both near and far objects, the outer layer flap is placed back over the eye.
The natural solutions of your eye will help seal the flap and heal your eye. You’ll likely need to keep a bandage on your eye for a few days. Also, the doctor will give you medications to keep the eye moist and infection-free.
