subject: Presbylasik - Presbyopia Laser Eye Treatment [print this page] With presbyopia, the lens placed inside the eye loses its capacity to shift focus. This condition is usually dominant and detectable in the early 40s and becomes lasting through one's life. This is usually rectified by using reading glasses, bifocals, or multifocal specs or contact lenses.
Regular laser eye treatment is also another procedure to right the eyes for well-defined distance sight. When presbyopia takes place, however, the near vision becomes blurry, making it crucial to utilization reading glasses. To correct this situation with laser eye surgery, one should need to look into presbylasik or multifocal lasik.
With presbylasik, the means of laser eye treatment involves using multiple powers on the front surface of the eye. Presbylasik allows the brain to picture simultaneously in the distance, intermediate, and up close, because it decides to focus on a single image.
The treatment can be performed in several ways.
For example, a center-near method of presbylasik means correcting the central part of the sight to make reading clearer and easier. Intermediate vision and well-defined distance sight is then adjusted to the surrounding region and the ring in the periphery, respectively The similar means is used in modern multifocal contact lenses. Individuals who suffer from presbyopia often complain of near sight problems which is often solved by locating the center of the vision for near to make reading more well-defined as compared to a distance-center way.
A center-distance approach, on the other hand, is a laser eye treatment that creates a clear cut central zone for distance vision while the surrounding area is treated for intermediate vision and the periphery for near sight. For those who choose distance vision, this is the regular way practiced by many laser eye specialists. Driving, playing sports like golf, and watching movies are just some of the universal activities that could benefit from a distance-center means.
Additionally, the visual acuity after undergoing laser eye treatment for presbyopia is outstanding. Not all people need glasses for daily tasks like driving or shopping. Even without glasses, perusing the newspaper is possible. Spectacles are needed, however, for activities that need complicated detail, such as needlework, to acquire comfortable sight.
Laser eye treatment side effects are also common occurrences with presbylasik. Some of these side effects include dry eyes and night-time glare and haloes throughout the first six months. Having dry eyes is remedied with eye drops while the glares become noticeably less over time.
Additionally, the screening tests performed on people prior to having laser eye treatment are similar to regular lasik.
Spectacle prescriptions are given.
Eye topography is taken by mapping the contours and thickness of the front of the eye.
A thorough health check on the eye is also performed.
Other factors that are taken into consideration for a successful laser eye treatment include the general health and medications currently being taken. For many surgeries, including laser eye operation, steroids and other drugs that hinder healing is not advisable.
A viable substitute to presbylasik is monovision laser eye treatment.
