Previous patients have to rely on using eyeglasses or contacts anytime and anywhere they are. These tools are very annoying sometimes. With the Lasik surgery, it is now possible to forget about these old days. The majority of people who have undergone the surgery have seen their vision improved and therefore can forget about their glasses or contacts.
As the technology is growing, several technologies can now be applied to the surgery in order to making it perfect. For instance the Wavefront technology is nowadays accessible and commonly used in the Lasik surgery. Other technologies include the diagnostic workstation and the Orbscan Technology.
Lasik surgery is designed to improve patients’ vision and its outcome is instantaneous. A special knife called microkeratome is used a thin, circular flap in the cornea. A good alternative involves using an excimer laser. The latter possibility is more accurate and therefore presents better outcomes.
Having cut the flap on the cornea, the Lasik surgeon folds it away from the path and removes additional cornea tissue. This is achieved by an excimer laser which makes uses of cool ultraviolet light beams to get rid of small pieces of additional tissue. Having removed it, the cornea is reformed resulting on a better focus light into the eye and onto the retina. As a result, patients’ vision is immediately improved. The flap is therefore restored to cover the missing area of the tissue.
The surgery is generally a quick and pain-free surgery for most patients. Throughout the surgery, patients are conscious and awake and can even walk after the surgery is done. The use of eye drops to anesthetize the eyes before the process is another reason why the surgery is pain-free. If patients feel uncomfortable before the surgery, they may take some mild sedative to feel better.
