Refractive Surgery
Refractive surgery is an operation that is performed on the eye and it is mostly done to correct the refractive defect. It can also be done to ensure that people get over their reliance on contact lenses and glasses. Some of the common refractive eye conditions that most people suffer from include myopia, which refers to nearsightedness. This condition is caused by a long eyeball that makes the eye to have too much focusing power. Another cause of myopia is an excessive curvature in the cornea and this ends up creating a steep surface. People with myopia will experience blurred images when focusing on objects that are at a distance. They can however see closer objects clearly.
Hyperopia is another refractive eye condition that refers to farsightedness. This means that the person lacks enough power to focus and therefore needs glasses or contact lenses to permit them see close range objects. This condition is caused by a short eyeball, which alters their power to focus. Another cause of hyperopia is less curvature in the cornea thus prompting images to fall behind the retina. Therefore, people with this condition will be able to focus clearly on distant objects while those closer to them will appear blurred.

The other refractive condition is astigmatism, which means that a person will not be able to have full focus on an object. This is brought about by the fact that the corneaS surface takes up an oval shape when ideally it is supposed to be spherical.
Presbyopia is yet another refractive condition that makes it hard for people to read. This condition mostly comes with advancement in age the cited ages being between 45 and 50. This is occasioned by the stiffness of the crystalline lens and this makes it hard to change shape. Refractive surgery is done to correct these conditions but one must meet the following qualifications. First, one must be 18 years or older and must have experienced stable vision before opting for refractive surgery. A personS eyes must be healthy meaning that they are free from corneal scars, retinal detachment, and other diseases that affect the eyes. Another qualification that a person must meet to undergo refractive surgery is to have a treatable eye problem.
Since refractive surgery is considered elective, a person must be willing to bear the cost that comes with it since many health insurances do not cater for it. Some of the refractive surgery options available include the photorefractive keratectomy (PRK), the LASIK (Laser in situ keratomileusis), the Excimer LASIK and the Radial Keratotomy. Refractive surgery is very beneficial to those who undergo it as it rules out the use of visual aids that are at times cumbersome. People in jobs such as firefighting, flying, and police departments are best suited for this procedure since they require visual acuity that discourages the use of visual aids. People with cosmetic reasons are also well covered by refractive surgery, as they may not want to wear glasses. Refractive surgery offers psychological relieve for those who feel handicapped out of restrictions presented by the visual aids they use.
