Lasik laser eye surgery is an advanced medical procedure to correct refractive error for the eyes. It allows you to improve the vision with reduced dependency over the contact lens and eye glasses. The laser surgery to improve the vision is not the only Lasik vision surgery, but there are many to choose one that suits you. Among the several laser variations of refractive surgeries, Lasik is usually referred as all kinds of laser eye surgery.
Though laser is a common agent that is made use in the vision surgery, there are different surgery procedures, like Lasik, PRK, LASEK. Each of the eye refractive error patient should select any one of these procedures, based on their eye conditions and various factors related to the eyes.
LASIK – The Laser-Assisted in-Situ Keratomileusis procedure is preferred by most of the eye patients, because of the better results that eventually can work for most of the activities. It has good track record, in terms of preference by people and success rate. Though there are a few side effects, like temporary visual disturbances and dry eyes, the same can be cleared in a few weeks. The best part is that the results are for long-term.
The Lasik procedure involves the procedure that alters the cornea curvature, by removing corneal tissues in tiny amounts. The surgeon flattens cornea curve and turns it to steeper.
PRK – Photorefractive Keratectomy involves the surgery procedure, which scraps top surface, the epithelium, away. This process of corneal abrasion needs only 3 to 4 days for healing, which involves short term blurred vision with moderate pain, before clear vision.
The PRK procedure is suitable for the people from different professions like military or law enforcement, where they more likely get to be struck. The advantage is that the risk of the rupture of eyeball is very low. It can correct nearsightedness, when not in severe condition or degree.
LASEK – Laser-Assisted Subepithelial Keratectomy procedure is quite the same as the Lasik surgery with small variation, creating flap is performed with microkeratome, a special cutting device and exposing cornea towards ethanol. This procedure removes only a very small part of cornea and so it is the best option for the people, who have only very thin corneas.
Epi-Lasik – Epithelial Laser-Assisted in-Situ Keratomileusis procedure involves separation of the epithelium out of the stroma, which is a central part of the cornea. the procedure makes use of the epikeratome or a blunt blade device and attempts the reshape of the cornea, using a laser. The procedure of Epi-Lasik is quite the same as LASEK.
Though there are multiple laser eye vision corrective surgeries, each of them is suitable for the people, as each of the eye condition is unique and hence the requirement is also unique. And only experienced surgeons can suggest you the best suitable laser eye surgery procedure, on the basis of the eye prescription and the general health condition.
