The varieties of common eye defects that originate from the deformity of the dome-shaped tissue in front of the eyes (cornea), such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, will alter the proper refraction and convergence of light to the back of the retina. The deformity of the cornea mitigates vision by causing blurry vision.
Nearsightedness (myopia): Myopia occurs when the cornea has an extreme curve beyond normal, thereby causing any light coming to the eyes to converge and focus in front of the retina. With this defect, you may partially see close objects but not distant objects that focus distance from the front retina.
Farsightedness (hyperopia): Hyperopia occurs when the cornea is flat without a proper curve to enable the converging of light entering the eyes; hence it results in the formation of images behind the retina instead of in it.
Astigmatism: Astigmatism combines the deformity of myopia and hyperopia but in an uneven manner—that is, the cornea may be curved or flat unevenly, which causes a disruption to the images formed from nearby or distant objects.
The blurry vision that is a symptom of the following eye defects can be corrected with the use of glasses or contact lens. A converging or diverging lens is the component that makes up the glasses or lenses one can use to correct blurry vision because they will enhance the formation of images on the retina.
The average cost of getting a contact lens ranges from about $30 to $70, while prescription glasses cost about $212. The individual using either of these instruments to enhance vision will need to change it several times within a year, which sporadically increases the sum of money you will on your eye defects per year and more in years to come.
However, you can save this money from your eye care expenses and perpetually correct your eye defects without the need for an additional lens to properly focus objects on your retina by opting for a LASIK surgery.
LASIK surgery, in which LASIK is an acronym for Laser In-situ Keratomileusis, is a prominent surgery procedure for the correction of eye defects—such as nearsightedness, farsightedness and astigmatism. The cause of most eye defects is the deformity of the cornea that is flat, extremely curved, unevenly flat or unevenly curved instead of having a dome shape.
You can correct them by wearing prescription glasses or contact lens that function in bringing the image to your retina by the diverging or converging of the rays of light that enters your eyes. A convex or concave lens is the component that enables vision correction in glasses or contact lens.
But several individuals may have similar eye defects but a totally different cornea; hence, the degree of effectiveness of these vision-correcting instruments will vary from one individual to the other. The best way to correct this is by reshaping the cornea back to its standard dome shape to forestall refractive errors that will result in several types of eye defects— this can only be done by LASIK surgery.
However, the term “surgery” makes people pessimistic about the risk it comes with. Still, when it comes to the correction of eye defects of several types, opting for LASIK surgery will provide you with incredible benefits that supersede the risk. If you are still in doubt, the following factors will convince you.
The first fear most individuals have against eye surgeries is because of how delicate the organ is and its susceptibility to immediate damage if there is a wrong move. But the use of LASIK technology will forestall this fear because it comes with the use of a computer-guided laser that enables precise and cautious movements when the surgeon is removing the microscopic agents responsible for your eye defects.
But before the commencement of your surgery, your ophthalmologist will run a few tests on you to detect the severity and type of eye defects you are suffering from before deciding on the best treatment procedure apt for your kind vision problem; because there are several types of LASIK surgeries and technologies.
Your doctor will also make a detailed map of your cornea to know how to shape it. Once healed, the clarity of vision you will get will be greater than it ever will be with the use of prescription glasses and contact lens.
The treatment procedure and recovery time are easier and do not take long, respectively.
LASIK surgery procedure does not involve the use of anesthesia because you will be awake during the shi, but the ophthalmologist may give anxious patients drugs to keep them calm. The surgery does not take more than thirty minutes before its completion. Once done, you will recover within at least two days of rest.
Some individuals experience several types of side effects that are usually mild and not perpetual because they cease to exist within days. The side effects of LASIK surgeries may include Starburst, halos, dry eyes, and extreme sensitivity to light.
The cost of LASIK surgeries is lesser than the benefits it offers to individuals with several eye defects. The average price for both eyes is less than $5,000, depending on your location and the type of LASIK treatment procedure you are taking.
Eye defects primarily occur as a result of cornea deformities from their normal dome shape, thereby leading to refractive errors. Refractive errors prevent the formation of images on the retina, but before or after the retina, this causes blurry vision.
You can, however, correct these vision problems— such as nearsightedness, farsightedness and astigmatism via the use of vision correcting instruments (glasses and contact lens) or opting for LASIK surgery. LASIK surgeries will provide you with a clearer vision than it ever was with your glasses or lens, at a cost that is less than the benefits it offers.
