Short-sightedness is a condition when a person is not able to see distant objects but is able to see for near. Various treatment options are available to correct short-sightedness. Different factors are considered while opting for the most suitable treatment option.
For clear vision, light should fall and focus straight on the retina. If the image is formed in front or behind the retina, the person may be able to see the object but not clearly. Once the light falls on the retina, the signal is sent from the retina to the brain through the optic nerve. The brain then processes the signal to visualize the object.
People with short-sightedness can see near objects clearly but have a blurred vision while seeing distant objects. It is because the image of the distant object is formed in front of the retina. In other words, in short-sighted patients, the light rays are unable to meet at one point on the retina.
Various options available for the management of short -sightedness are aimed to focus the light rays straight on the retina.
Short-sightedness can be managed through the following options:
Glasses: Wearing glasses is one of the most common ways to correct short-sightedness. Glasses correct the vision by focussing the light on the retina. It is considered as a safe and effective way to correct refractive error of eyes. Various types of corrective lenses are available. Some lenses, apart from correcting vision, also protect the eyes from harmful UV radiation.
Contact lens: Contact lenses are an option for those people who do not want to wear glasses. The person has to wear contact lenses directly into their eyes. As contact lens comes directly in contact with the cornea, proper care of the lens is required to prevent the risk of infection.
Lasik Laser eye surgery: LASER eye surgery is an option for those people who want to avoid wearing glasses and contact lenses permanently. During LASIK surgery, the corneal flap is formed through a microkeratome or a Femtosecond laser .This corneal flap is folded to expose the corneal tissue. The cornea is reshaped with the help of an excimer laser.
Clear lens extraction: This procedure is also called as refractive lensectomy. The procedure is done in those patients in which LASER surgery is not possible. They are used to correct short-sightedness and far-sightedness. An important advantage of this procedure is that the person does not develop a cataract in the future as the natural lens is replaced with a synthetic artificial lens which functions like a normal lens .
Although various options for managing short-sightedness are available, there are various factors to be considered while opting for the options:
