When an eye has errors of refraction they are corrected by a procedure known as Lasik in Dallas. This surgery is carried out for the improvement of the patients visual clarity. It is a procedure to reshape the cornea. It is for the treatment of vision errors such a long and short sightedness as well as astigmatism. It is also to reduce the dependency of a patient on contact lenses and glasses. The refractive disorder causes patients to have blurry vision but the surgery improves their accuracy in vision.
To be able to undergo Lasik surgery there are several conditions that one must fulfill. There is an age limit. Patients have to be above the age of eighteen. There should be no refraction change for a period of at least one year and the patient has to have a realistic expectation of the outcome. A patient who has had an eye infection or an eye injury within the past one year is also not an eligible Lasik eye surgery patient.
Before the surgery is performed there is an examination that is known as a pre Lasik exam that has to be carried out. Some eye drops to anesthetize the eye are put in the eye. The surgeon will have created a corneal flap that is hinged. A flap is then created on the outer side of the eye which exposes the cornea. This flap is created by a laser that is guided by a computer. The cornea is then reshaped by an excimer laser and then it is replaced.
Improved vision is experienced immediately though it may take a few months before there is stability of the vision. In most cases results are satisfactory and patients have an improved vision and are free from corrective lenses and glasses. It is not only a safe procedure but also an effective treatment option.
A very negligible number of patients experience complications though there are several advances in Lasik technology that are increasingly eliminating these complications. They are the risks that may be increased sensitivity to light or the fluid that moistens the eye becomes affected in its production. Thankfully additional treatment does it to correct the risks that occur.
If you are interested in the surgery but want to get more information you can talk to your ophthalmologist or check on the web for developments on the technology. Basically they employ the use of excimer laser which is very precise and it penetrates a very small amount of tissue at a time therefore it increases the accuracy.
In choosing a surgeon go for an experienced qualified physician who has become reputable. Do a thorough research putting your personal concerns as the point of choice. The question of costs and location of surgeons office should not influence your decision.
