Eye problems are not unusual especially for people today as there are a lot of factors that can cause problems to one’s eyesight. Contact lenses and eyeglasses has long been used to solve these problems but a more modern treatment in the form of laser sight eye surgery has attracted its fair share of interested patients. The results of this procedure have astounded people from all over the world although it does come with some questions. Here are some of the basics involving this procedure:
LASIK and how it works
Credit for Lasik which stands for Lase in situ Keratomileusis has been given to Ioannis Pallikaris who is of Greek origin. This procedure has been around since 1991. Laser surgery alters the share of the transparent film covering the eye known as the cornea with the use of the specialized excimer laser to correct one’s vision. With this, refractive errors are corrected leading to improved vision and eliminating the need for contact lenses or glasses.
Common refractive errors requiring corneal correction
Given the strain that the eye goes through on a daily basis, it is not surprising why a lot of people have vision problems;even the younger set has their fair share of eye problems. Among the most common eye problems that younger people have include:nearsightedness or myopia, farsightedness or hyperopia and astigmatism.
Before undergoing the laser eye surgery, all patients are required to undergo an eye examination to ensure that they are good candidates for the procedure. There are no absolute rules when it comes to determining whether someone is good enough for the procedure or not based on age. However, often enough, older patients run the risk of having cataract or other eye problems that will rule out the procedure. On the other hand, those who are below 18 years of age have eye conditions that are too unstable for them to undergo surgery.
Requirements for laser surgery candidates
Before any individual decides to undergo laser surgery, it is essential to undergo an eye examination to ensure that the candidate can undergo the procedure. There are several factors that will need to be addressed while screening candidates such as the progression of their eye condition. Although a change in the condition is not at all uncommon, if the progression is quite strong, it will not be in the best interest of the patient. Autoimmune diseases and other conditions will also affect an individual’s suitability for the operation. There are even instances when an individual needs to inquire whether his or her company will not preclude him or her to undergo the operation.
Risk factors for laser surgery patients
During the eye examination, the doctor will be looking into certain conditions that will make you a less than ideal candidate for laser surgery. These things include clients with high prescriptions. In this case, too much corneal tissue would need to be removed and this would be impossible to perform without causing too much damage. Individuals with thin corneas are also poor candidates for the procedure as corneal tissue would need to be removed and so the current thickness of the cornea is measured before the performance of the surgery. An abnormal curvature of the cornea is another factor that needs to be considered ad there’s dry eyes which is quite usual in older patients. Tear secretion can be a problem after surgery and if this problem is already present, it may not yield the best results.
There is no denying that laser eye surgery is just short of a miracle especially for those who have suffered from poor vision since their younger years. Nevertheless, it is not for everyone and care should be exercised in determining whether it’s for you or not.
