What should I expect from presbyopia operation?
Presbyopia is a condition in which the eye loses the ability to concentrate on nearby objects. It affects most people at the age of 40 and, in some cases, presbyopia surgery can be used to treat the problem. There are a number of different operations, some of which change the shape of the eyeball and others that insert the type of lens. Sometimes people can learn to use what is called Monovision, where one eye is adapted for almost vision and the other eye leaves viewing distant objects. None of the techniques offers a perfect solution and for some people may be preferred glasses or contact lenses, but surgery for presbyopia, although not without risk, can provide an acceptable range of vision for some individuals. for reading. The dominant eye is the COH brain prefers, in the same way as humans are naturally left or right -handed. Not everyone can learn to use monovision and it is recommended for people to try Monovision contact lenses before committing to surgery. Perfect vision is not guaranteed Po Lasik, but people usually need to use glasses or contact lenses less than before.
people with presbyopia and sight, which is otherwise normal, can be suitable for surgery known as conductive keratoplasty. Instead of lasers, radio waves are used to reduce areas around the edges of the cornea, transparent eyeball coverage. This transforms the eyeball, which makes the curvature more steep in the middle and effectively extend it. The eye becomes almost revealing, so it can be used for close work, such as reading, and a dominant eye for distance vision. It is again important to determine that the person is able to function using monovision before surgery.
These two methods of presbyopia surgery usually require only a few hours to stay at the clinic. Immediately after surgery, a slight discomfort or blurred vision may occur and may be necessary to wear protective dark glasses to avoid getting water or other substances into the eye and for the eyeto tune in one day. Any surgery on the second eye is usually performed at least a week after the first procedure. Most people experience a satisfactory result after presbyopia surgery, but complications such as loss of vision may occur very rarely.
In addition to these types of presbyopia surgery, there are a number of other treatments that are not widely available or are currently in a study. They include the use of gas bubbles to transform the eye, insert artificial lenses similar to those used in cataract surgery, corneal implants, and create more zones on the front of the eye. The ophthalmologist will be able to recognize which, if at all, the technique of the eye surgery is suitable.
