LASEK is a surgical procedure that aims to correct deficiencies in vision and reduce or eliminate dependency on prescription eyeglasses. The procedure uses a laser for reshaping the cornea of the eye.
Many people consider LASEK and LASIK to be similar procedures. In effect, they resemble each other because they produce similar results. However, the way in which they accomplish this aim is very different.
LASEK stands for Laser Epithelial Keratins. The procedure changes the shape of the cornea permanently by evaporating small parts of the cornea. The result is proper correction in the focus of the eye.
At the start of the procedure, the outer layer of the cornea is removed and pushed aside. Once the surface is exposed, the reshaping process starts. Once the process is over, the layer that was pushed aside is restored over the cornea. A clear contact lens is applied over the area to protect the now sensitive cornea and to ensure a complication free healing process.
The procedure is often recommended of nearsightedness and farsightedness. The choice of the procedure depends on factors such as nature of the refractive error, condition of the eye and the overall health of the patient.
The result of the procedure is often a complete correction in the refractive error of the eye. Thus, the patient is able to see at the full 20/20 vision. The time taken for an average LASEK procedure is about twenty minutes. The patient is able to make s full recovery within weeks of the operation.
