There are four main refractive surgery techniques. Now the general operations of laser to reshape the cornea aid. The four types of eye surgery corrective actions that we are talking about in this piece corneal incision techniques, flap and photoablation techniques, thermal techniques and implants.
Using corneal incision method, a diamond-tipped knife to make very small incisions in the cornea. This alters the surface of the cornea and is used to fixany visual defect. Since the use of lasers has taken place in the world of medicine, is not this technology be used as often now.
Flap techniques simply cut a small flap in the cornea, so that they will be redesigned, and the refractive issues. LASIK is often the general nature of this type of technology. If using a laser beam to create the flap and takes no additional tissue. Then the flap is restored and smoothed so that a thin cornea. Photoablation is the secondary step in the doorTechniques, where ultraviolet radiation is used to remove excess tissue from the cornea. It is a cool and heat so as not to interfere and to the comprehensive eye tissue. Once the fabric is made, the cornea can be revised to correct the vision problem.
Thermal techniques are used to correct farsightedness to temporarily. 8-16 small burns with heat in a ring around the pupil. Thus, the cornea will be steeper. The heat can be applied either with a laser, and aelectric probe.
Implants are contact lenses, which were always implanted behind the cornea. This technique is most often the only choice in an extreme vision issues.
In most types of operations can lead to problems. Although scarce, you should be aware of the possibilities. In flap surgery, sometimes caused a perforation in the eye. This does not happen often, and is usually only used in older devices. Both the flap methods, it can sometimes irregularFlap, or a small particle can be there before the door is closed, so you can see "floaters" in your line of sight. Laser Questions happened in less than 1% of eye surgery done today.
As well, you may experience some problems during the course of healing. A few people go through issues such as vision halos of light, starbursts, double vision, or a constant glare. In addition, your night vision will not be affected. These problems usually decrease over time. Rub your eyesafter an eye operation. In the flap technique, the flap can actually be set by City and pain and irritation of the eyes, bloodshot eyes and out of service. The most common side effect of eye surgery is dry eyes. This can be helped with some eye drops. As with any surgery, there is certainly a risk of infection, which will slow the progression of healing. However, you can be helped with antibiotics.
The duration of treatment depends on the operation. There can be only for a few days orlast up to a month. Whichever technique you choose, make sure that you talk about it carefully with your doctor. (It is worth getting a second opinion or two.) If you are tired of wearing glasses or contact lenses, eye surgery, corrective action will only accurate choice can for you.
