Devices for Victims of AMD

Added 17/11/2010

Victims of AMD (age-related Macular Degeneration) will have to suffer a lot in their work and daily lives. For example, they can not deal with nearby tasks, like reading. And the symptom worsens as the problem progresses. Therefore, it is needed to find some aiding devices for better vision.

People with AMD should first consult with their eye doctors before buying low-vision devices of any kinds. Eye doctors will first lead some eye exams to see what the specific problem and condition is. Based on people’s personal situation and needs, some specialized aiding devices or eye wear will be prescribed. Of course, the task or purposes also determine the making of these aiding devices or eye wear.

People who often read or do other nearby task are in need of near vision devices; those who often use computer or do other intermediary job need middle vision devices; those who often drive need far vision aiding devices.

People who have to read or do other things at arm-length distance may use magnifiers of certain kinds. But these devices may cause inconvenience sometimes. And some eye wear might be much better options. These eyeglasses can offer different vision effects for victims with different needs. For example, there are in the market bioptic eye wear. These eyeglasses can ensure two different vision fields.

Of course, there are now more and more inventions for people with AMD, as technology advances. For examples, some speakers can be found in certain documents or devices. All these devices can really benefit victims of AMD greatly both in their work and daily lives.

An Instruction of Lasik Surgery

Added 16/11/2010

Prior to make an decision to have an eye surgery to correct vision, to consider what types of surgeries, a normal refractive eye surgery or a custom lasik surgery, is more suitable to you is crucial. In spit that lasik performs well in vision correction, however, not everyone is a good candidate for it. Wrongly undergoing such a surgery would result in serious consequences. Therefore, you are suggested to know the types of lasik surgery, and respective features and performs firstly.

There are different types of lasik up to now, and the differences lying among all of them is concerned with the way the mapping system that guides the way laser works. During the process, the wavefront, which is firstly applied by astronomers to correctly guide the optics of their telescope for better vision, plays a rather important role in detecting the aberrations. Compared with the ordinary eye surgeries, where there is no wavefront applied, it is hardly to detect the aberration accurately, instead such a detection depends on the observation of the surgeon. In some degree, errors are possible merely through the surgeon's detection. Another function of the wavefront is that after detecting the aberrations, it would correct those aberrations through guided ablations. Then it would be easily concluded that lasik is a rather automatic surgery, controlled by a computer. That is to say, lasik can accomplish an correction fairly accurately.

When the aberration is mentioned, it should be illustrated that the aberration can be classified into two types: LOA or lower order aberration and HOA or higher order aberration. The former one can be easily detected through observation of the surgeon and can be corrected by commonly known refractive techniques; while the latter one comes to be comparative more difficult for a surgeon to detect it, and then when coming across HOA, wavefront should be selected. Wavefront also helps the surgeon understand whether one needs wavefront ablation or not. That is to say, wavefront are both useful in the confirmation of whether one is in need of a custom lasik surgery and performance in correcting aberration by wavefront ablation.

With such a brief instruction of lasik surgery above, it is hoped that you would make a right choice in choosing a conventional refractive surgery or a custom lasik surgery to get your vision corrected.
