One type of vision problem is hyperopia which is usually called farsightedness. Those who have farsighted vision do not have any problems seeing things at a distance. However, they do have a lot of problems when they must view something up close, such as, with reading. People who are farsighted require reading classes. Reading glasses make it easier to see, which in turn prevents squinting and fatigue on the eyes. People that are farsighted have shorter eyeballs or a cornea that is too flat which leads the light to focus behind the retina causing problems with near viewing.
Traditionally, farsightedness has been treated with either glasses or contact lenses. However, advances in medicine have now made it possible to surgically correct farsightedness. There are many different laser treatment procedures that can used. LASIK surgery is the overwhelming favorite of both patients and opticians alike.
LASIK surgery treats farsightedness by reshaping the cornea’s surface. As a result, it is better able to focus light making it much easier to see things close up. During the procedure, a flap is cut into the other part of the cornea. The tissue is then removed or ablated with a laser. This creates more of a slope in the cornea which improves its ability to focus light. LASIK is not only used to treat farsightedness but it’s also a great laser treatment for nearsightedness and astigmatisms.
While LASIK is a fairly low risk procedure, it is still surgery so it should be considered carefully. Some people who have difficult focusing may actually have presbyopia which occurs from natural aging. If a patient’s nearsightedness is due to this condition, LASIK may not be an appropriate procedure. In some cases, even if the patient has the LASIK, they may still need reading glasses if their sight deterioration is due to presbyopia. Your doctor will examine your eyes and look at all factors and recommend this procedure if you meet the qualifications.
Presbyopia correction surgery is nowadays available too. It can be done with our without the use of a laser. The procedure focuses on the cornea and lens. The laser surgeries include Monovision or Multifocal LASIK procedures or the IntraCor laser intervention. If we refer to the non-laser surgery options available for presbyopia treatment, we have to mention Conductive Keratoplasty, Corneal implants, refractive cataract surgery and refractive lens exchange.
The number of patients diagnosed with presbyopia is constantly growing in the United States, United Kingdom and everywhere in the world. Yearly an increased number of people require presbyopia correction surgery and this is why these type of procedures are constantly developed and improved. Stay tuned for more updates on this subject.
