With presbyopia, the lens situated inside the eye loses its capacity to shift focus.
This situation is typically prevalent and noticeable in the early 40s and becomes permanent through one's life.
This is mostly rectified by using reading glasses, bifocals, or multifocal specs or contact lenses.
Regular laser eye treatment is also another procedure to correct the eyes for clear cut distance vision.
When presbyopia takes place, however, the near sight becomes blurred, making it crucial to utilization reading glasses.
To rectify this situation with 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 perceive simultaneously in the distance, intermediate, and up close, because it decides to concentrate on a single image.
The treatment can be performed in different ways.
For example, a center-near way of presbylasik means correcting the central part of the sight to make reading clearer and easier.
Intermediate vision and well-defined distance vision is then adjusted to the surrounding section and the ring in the periphery, respectively The similar method is used in advanced multifocal contact lenses.
Individuals who suffer from presbyopia often complain of near vision 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 method.
A center-distance way, on the other hand, is a laser eye treatment that creates a clear central zone for distance sight while the surrounding area is treated for intermediate sight and the periphery for near sight.
For those who favor distance vision, this is the widespread technique practiced by many laser eye specialists.
Driving, playing sports like golf, and watching movies are just some of the usual activities that could profit from a distance-center approach.
In addition, the visual acuity after undergoing laser eye treatment for presbyopia is incomparable.
Not all people require eyeglasses for daily tasks like driving or shopping.
Even without glasses, reading the paper is feasible.
Glasses are needed, however, for activities that necessitate intricate detail, such as needlework, to acquire comfortable sight.
Laser eye treatment side effects are also regular occurrences with presbylasik.
Some of these side effects include dry eyes and night-time glare and haloes during the first six months.
Having dry eyes is remedied with eye drops while the glares get observably less over time.
Additionally, the screening tests performed on individuals prior to having treatment are comparable to regular lasik.
Spectacle prescriptions are given.
Eye geography is taken by mapping the contours and thickness of the front of the eye.
A detailed 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 feasible alternative to presbylasik is monovision laser eye treatment.
