Glasses are a passe, see Lasik way
The Lasik technology was first introduced way back in 1960 by a Spanish ophthalmologist. At that time, he developed the first microkeratome which was used to change the shape of cornea and cut thin flaps in the cornea region. With more research in this field this technology has become popular and affordable. Now Lasik eye surgery can be performed within a span of a few minutes with help of laser. Those planning o go for this operations are advised to stop wearing contact lenses 10-15 days from the date of operation. Plain laser surgery includes Epi-laser as well.
Lasik eye surgery is performed in 2 stages. In the first step a flap of corneal tissue is created in which corneal suction ring is applied to the patients eye. In this process, sometimes, blood vessel gets burst and resulting in bleeding, though gets resolved within few weeks. In the second step, excimer laser is used to remodel the corneal stroma. The Lasik laser in this stage is used for vaporizing of tissues in a controlled manner and then layers of tissues are removed which are tens of micrometers thick. At the second stage, the patients vision becomes blurry and he or she is able to see only white light around the laser.
Epi Lasik - safe and sound
Lasik eye surgery has been developed in many forms. One of its forms is Wavefront guided Lasik wherein an ophthalmologist applies computers guided and guided excimer laser and it has measurements from a wavefront sensor laser technology. The goal of this is to restore perfect vision in the patients eyes. This technology does not result in super vision. You can't expect 100% eye vision from this. Yet, surgeons have claimed that patients who are treated by this method are more satisfied than with the previous methods. With the advantage of lower cost and easier surgery associated with it, this method is really becoming popular. |
