Nearsightedness or Myopia is an eye condition that makes it hard for a person to see distant objects. Person with myopia can clearly see near objects however, farther objects may seem blur. Maybe the eyeball is too long that causes the light rays to focus at one point in front of the retina rather than directly on its surface. Another cause can be because cornea and/or lens are too curved for the length of the eyeball. In some cases, it is a combination of these factors.
Myopia tends to be inherited and develop gradually or rapidly during childhood and adolescence.
Aside from difficulty to clearly see distant objects, myopia may also include symptoms such as:
- Eye Strain
Nearsightedness is usually discovered during childhood. A series of eye tests may be used to confirm the diagnosis. The doctor may use various instruments, aim bright lights directly at your eyes and ask you to look through several lenses. This will help in prescribing the correct lens or eyeglass.
Various treatment may be used to temporarily or permanently correct this eye problem, including:
- Corrective Lenses – You may use corrective lenses in a form of either eyeglasses or contact lenses.
- Refractive Surgery – This procedure uses laser beams to reshape the cornea to improve vision and reduce the need for eyeglass or contact lens.
Refractive surgical procedures may include:
- Laser-assisted in-situ Keratomileusis (LASIK)- The eye surgeon makes a thin, hinged flap in the cornea then uses an excimer laser to remove layers from the center of your cornea to flatten its domed shape.
- Laser-assisted Subepithelial Keratectomy (LASEK)- the surgeon creates a flap only in the cornea’s thin protective cover (epithelium) then he or she uses an excimer laser to reshape the cornea’s outer layers and flatten its curvature and then repositions the epithelial flap.
- Photorefractive Keratectomy (PRK)- It is similar to LASEK, except the eye surgeon removes the epithelium.
- Intraocular lens (IOL) Implant- A lens is implanted in front of the eye’s natual lens.
Unsuccessful surgery may result to more complications and serious side effects.
