Chancel-LASIK - Not Available immediately
February 22nd, 2010 LASIK is elective surgery the most common today in the United States. Presbyopia ( "old eyes") is the most common problem that affects vision every 50 years above. However, this common problem and a common solution had trouble staying together.
This type of surgery is generally used to treat nearsightedness, farsightedness and asytgmatism. And 'most successful on people in their 20s, 30s and 40s. At age 50, many people feel the effects of presbyopia,making it increasingly difficult to near vision, a different way of seeing before. (Photo Seniors take their documents at arm's length to try to read them. This is presbyopia in action.) Even people who have undergone laser eye surgery in their youth may have still need reading glasses with age.
Monovision LASIK surgery LASIK is currently the most widely used to treat presbyopia. This procedure corrects your dominant eye for distance vision and the non-dominanteye for near vision. Depending on what you watch, your brain decides to use his eyes and ignores "(out-of-focus) the contribution of the other eye. Many people respond incredibly well to monovision, but his backhand.
With monovision, whenever the vision really cool, however, when near or far, you need glasses in May to allow the use of both eyes simultaneously. This is particularly true in situations where depth perception (which requires both eyes) isrequired.
For this reason, other procedures to correct presbyopia (known as "sanctuary-LASIK") have long been under development. The most common approach is to split the different areas of the cornea, so that parts of your cornea can be used for remote viewing and other parts for near vision.
While technologies have improved (as Wavefront to map the specific eye of each patient and all procedures IntraLase) the success of the choir-LASIK isincreased. However, even today, the procedure is not approved by the FDA. The only way to have this procedure in the United States as part of a research experience.
Studies have shown the procedure to be able to add more near vision back into the repertoire of patients with vision. Has not been able to restore distance vision in patients with myopia, although researchers continue to seek new methods and better results.
More research isnecessary in the ideal viewing areas around the cornea. The possibility exists that there is no "ideal" arrangement is agreed. Instead, a customized approach may eventually be taken with the presbytery-LASIK, in which the daily priority of each person to determine the best surgical approach for them. Patients using the near vision for reading or detailed work in May set a near vision, as their priority, while others may define the distance vision, as the most important.
AlthoughSurgeons could lead rectory LASIK patients outside the United States, the procedure is generally considered "not ready for prime time." However, given the speed with which the techniques of laser eye surgery have improved, can not be long before we have a surgical option that gives us a clear view through all the decades of our lives.
