If you wear glasses then you may be pleased to know that there is surgery available that can ensure you are rid of them for good. In fact there are a range of surgeries and treatments that can ensure you never again need to rely on glasses or contact lenses to see clearly.

Refractive lens exchange (RLE) has helped thousands of people across the UK throw their glasses away. Think of it as an advanced form of cataract surgery which is one of the most commonly performed surgeries in the world. RLE involves removing the existing lens of the eye and replacing it with an artificial one, this is how it is like cataract surgery. However RLE involves the replacement lens being a prescription lens. It is an ideal treatment for people over 50 who want to have their youthful vision return. The remarkable thing about this type of treatment is that it can correct two problems in one. Not only does it instantly remove cataracts from the eye, but it can also correct refractive problems such as long or shortsightedness. Cataracts are the clouding of the natural lens of the eye. If the lens is replaced with an artificial one the cataract disappears. Furthermore it can never return because the artificial lens cannot harden or go cloudy with age. The artificial lens can be specially created for the individual so that as well as removing the cataract it can also correct a refractive problem.


Another eye surgery that is available is laser vision correction or laser eye surgery as it is also known. There are in fact two types of laser eye surgery, LASIK and LASEK. Laser vision correction is very efficient at reshaping the cornea so refractive errors can be dealt with. Lasik surgery is the more common of the two surgeries. During the surgery a flap is made and the surface of the cornea is peeled back. Lasers then reshape the cornea before the flap gets put back into place. This surgery is ideal for myopia, hyperopia and astigmatism in particular.

Lasek surgery is less common because the healing period is slightly longer. It is used for less serious conditions of the eye or minor refractive problems. It is also the more suitable option for people with thin corneas. Instead of a flap being made the cornea surface is simply loosened and then folded back. Lasers are then used to make the necessary alterations to the shape of the cornea.

The results after all of these surgeries are incredibly impressive. Almost instant results can be seen with sight continuing to improve for up to 6 weeks. People who have worn glasses all their lives are amazed at the improvement to their sight. It truly is life changing for people who have had to rely on glasses for so long. Surgery is available for many problems and conditions of the eye. If you would like to know more about eye surgery then your first step is to talk to your local eye hospital. An alternative to laser eye surgery however is Clarivu refractive lens exchange which is provided by one of the UKs leading private eye hospitals. Clarivu provides a permanent alternative to laser eye surgery which is particularly suitable for the over 50s.


All the eye surgeries mentioned above are extremely safe. The eye heals on its own and very quickly. There may be eye drops needed for a while following the surgery and a follow up appointment will also be necessary with the surgeon to check on the healing process. Otherwise however life can get back to normal just a few days following treatment. Those who undergo refractive lens exchange can be back at work just two days later. Aside from resting the eyes following surgery and avoiding smoky or dusty environments, there is little else needed to aid the healing process.

If you are keen to live without glasses then either refractive surgery or laser eye surgery could help. Contact your local eye doctor to discuss eye lens surgery and find out more about an intraocular lens implant.

Eyeglass Frame Materials

Different eyeglass frame materials greatly expand your options for a new look. While shopping for new eyeglasses or sunglasses, ask your optician for advice about variety in colors, durability, lightness, favorite brands, hypoallergenic materials, uniqueness and price.

In fact, finding eyeglasses with the qualities that are most important to you could be as simple as choosing the right frame material, because each type has its own unique strengths.
Plastic

If you want the colors of the rainbow, then zyl (zylonite, or cellulose acetate) is your material. Zyl is a very cost-effective and creative option for eyewear and is extremely lightweight. Particularly popular right now are laminated zyl frames that have layered colors. Look for light colors on the interior sides, which can make your eyewear "disappear" from your visual field when you wear them. An all-black frame, on the other hand, is visible at all times on both interior and exterior sides.

Some manufacturers also use cellulose acetate propionate, a nylon-based plastic that is hypoallergenic. It's lightweight and has more transparency and gloss than other plastics. If your main criterion for a frame is lightness, then definitely consider propionate frames.

Eyeglasses made of nylon first were introduced in the late 1940s. Because of brittleness and other problems, eyeglass manufacturers switched to blended nylon (polyamides, co-polyamides and gliamides). Today's blended nylon frames are both strong and lightweight.

Nylon is also a premier material for sports and performance frames, typically made of gliamides, grilamid or trogamid materials that are very resistant to hot and cold and are more flexible, yet also stiff. Nylon also is easily molded into today's popular wraparound styles, as well as other shapes that are difficult to produce.

It may sound odd, but plastic made of castor oil (actually, castor seed oil) is now used in some eyewear. Traditionally used as a laxative, a soap ingredient and a machinery lubricant, castor oil is also making its way into plastic auto parts, along with other non-petroleum-based plastics. Reasons for castor oil plastic development include the high price of petroleum and the ease of growing castor bean plants in places where other profitable plants don't thrive.

Plastic frames do have some drawbacks. They are easier to break than metal frames, they will burn (but are not easily ignited), and aging and exposure to sunlight decrease their strength slightly. Color can fade over time, but not as much with modern materials.

Metal

Monel — a mixture of any of a broad range of metals — is the most widely used material in the manufacture of eyeglass frames. Its malleability and corrosion resistance are pluses.
Still, it is not 100 percent corrosion-resistant: for some people, monel can react with their skin chemistry. But this is preventable if the right kind of plating, such as palladium or other nickel-free options, is used.

Many frame manufacturers offer titanium and beta-titanium styles these days; titanium is a silver-gray metal that's lightweight, durable, strong and corrosion-resistant. It has been used for everything from the Gemini and Apollo space capsules to medical implants such as heart valves.

Titanium eyewear can be produced in a variety of colors for a clean, modern look with a hint of color. And they're hypoallergenic.

Some titanium farmes are made from an alloy that is a combination of titanium and other metals, such as nickel or copper. In general, titanium alloy frames cost less than 100 percent titanium frames.

Beryllium, a steel-gray metal, is a lower-cost alternative to titanium eyewear. It resists corrosion and tarnish, making it an excellent choice for wearers who have high skin acidity or spend a good amount of time in or around salt water.

Beryllium is also lightweight, very strong, very flexible (making it easy for an optician to adjust your glasses) and available in a wide range of colors.

Personal Reasons of Eye Care

Eye care is essential to maintaining the health of our eyes. People with eye diseases that greatly affect their vision face many problems. They are physically hampered by impaired vision. They are not able to perform daily activities like driving or working. Some are barely able to see or have lost their vision entirely. They are also faced with emotional stress.

Certain diseases might be causes by other factors such as obesity, diabetics, exposure to ultraviolet light, smoking, certain medications such as steroids, and many other factors. It is a good idea to ask your eye care doctor for specific steps you can take. People with obesity or who are diabetic should have more routine checkups since they are more likely to develop certain eye diseases.

Diseases of the Eye

Severe burns of the face often involve the eyelids. The treatment is the same as for burns on other parts of the face except that great care must be used to preserve tissues still capable of healing. Chemical burns involving the eye should be given prompt first aid by rinsing the eye with generous quantities of flowing water or milk. The eyelids should be separated so that the rinsing includes their under surfaces. A physician should take over the care of the patient as soon as possible.

Cataract
In cataract the lens of the eye becomes progressively opaque. The patient first notices a reduction in the acuteness of vision. As the cataract progresses, his vision continues to fail until he can perceive only light and darkness. Frequently cataracts develop at about the same time in both eyes. Of the various types, senile cataract is the most common. It typically develops after the age of fifty.Certain diseases predispose to early development of cataracts, notably diabetes. Sometimes a cataract develops following an eye injury. Long-continued exposure of the eyes to high temperatures, as with workers in glassblowing and iron puddling, favors the development of cataract.

What To Do
1. Consult a physician who specializes in eye diseases (an ophthalmologist).
2. The usual treatment for cataract is surgical removal of the opaque lens. After surgery, light can enter the eye in the normal manner, but because there is no lens the light rays do not focus on the retina. Visual images are blurred and distorted.
3. Therefore the patient must be supplied with artificial lenses in one of tree ways:
a: The wearing of glasses fitted with specially adapted lenses. Such lenses appear thick, but provide reasonably good vision in a central visual field. Lateral vision is somewhat limited.
b: The wearing of contact lenses which rest on the eye itself (beneath the lids) and are of proper size to enclose only the cornea of the eye. When properly fitted, contact lenses provide satisfactory distant vision so that the person sees essentially as well as before. For reading, glasses must be used in addition to the contact lenses.
c: The installation of implanted lenses ("implants"). In this instance, a small, specially prepared plastic lens is inserted into the eye at the time of cataract surgery. Implanted lenses have been in use in Europe for several years. Their use in the United States is relatively recent. There are certain technical difficulties that may cause problems when lens implants are used.

FCC OKs on-body medical networks

The U.S. Federal Communications Commission adopted rules at a meeting on Wednesday to allow wireless networks of microstimulators designed to treat paralysis and other conditions.

Buy Affordable Buy Glasses Online and Eye Care Glasses Online at Eyecareglassesonline.com

The agency approved the use of MMNs (medical micropower networks) in four blocks of the 400MHz spectrum band despite opposition from broadcast engineers who say they are concerned about interference. One of the frequency blocks is used by trucks that send live media reports back to TV and radio stations.

Microstimulators implanted next to nerves can stimulate those nerves through electrical charges, causing muscles to contract and limbs to move. MMNs can link dozens of those stimulators to devices that take in signals from the human nervous system, bypassing areas of the nervous system that have been impaired by strokes or spinal cord or brain injuries.

The Alfred Mann Foundation (AMF), which has developed prototype MMNs, sought access to the spectrum for these systems in 2009. It did not seek exclusive access to the frequencies and said the new networks could coexist with other users. In a press release on Wednesday, the FCC called the new rules an example of how "spectrum-agile" radios can make more efficient use of scarce spectrum.

In a related development, the agency's Office of Engineering and Technology issued an order allowing Second Sight Medical Products to sell a retinal prosthesis that uses wireless transmissions to restore sight to the blind through a miniature video camera mounted on a pair of glasses. The camera sends images to a video processing unit, and the video is then sent wirelessly to a neurostimulator implanted on the eye. It is designed for people with advanced retinal degenerative disease.

FCC OKs on-body medical networks

The U.S. Federal Communications Commission adopted rules at a meeting on Wednesday to allow wireless networks of microstimulators designed to treat paralysis and other conditions.

The agency approved the use of MMNs (medical micropower networks) in four blocks of the 400MHz spectrum band despite opposition from broadcast engineers who say they are concerned about interference. One of the frequency blocks is used by trucks that send live media reports back to TV and radio stations.

Microstimulators implanted next to nerves can stimulate those nerves through electrical charges, causing muscles to contract and limbs to move. MMNs can link dozens of those stimulators to devices that take in signals from the human nervous system, bypassing areas of the nervous system that have been impaired by strokes or spinal cord or brain injuries.

The Alfred Mann Foundation (AMF), which has developed prototype MMNs, sought access to the spectrum for these systems in 2009. It did not seek exclusive access to the frequencies and said the new networks could coexist with other users. In a press release on Wednesday, the FCC called the new rules an example of how "spectrum-agile" radios can make more efficient use of scarce spectrum.

In a related development, the agency's Office of Engineering and Technology issued an order allowing Second Sight Medical Products to sell a retinal prosthesis that uses wireless transmissions to restore sight to the blind through a miniature video camera mounted on a pair of glasses. The camera sends images to a video processing unit, and the video is then sent wirelessly to a neurostimulator implanted on the eye. It is designed for people with advanced retinal degenerative disease.

The Eye Of The Fly: Researchers Discover Possible Key To Degenerative Nerve Diseases

Researchers at the University of Wisconsin-Madison and collaborators have discovered a powerful new protein in the eye of the fruit fly that may shed light on blinding diseases and other sensory problems in humans.

Reporting in the Nov. 16, 2011, issue of Neuron, the scientists note that similar but yet- to-be-identified proteins in the eye and brain could help explain age-related macular degeneration and retinitis pigmentosa, as well as Huntington's, Parkinson's, Alzheimer's and prion diseases.

The protein, which the scientists have named XPORT, serves as a chaperone for two important proteins that are key to sensory activities in the eye. One protein, rhodopsin, is responsible for absorbing light, and the other protein, TRP, is a channel that plays a role in calcium influx into cells. XPORT guides the two proteins from the place where they are made in the cell to the location where they do their jobs.

This intricate process of chaperoning includes synthesis, folding, assembly, quality control, transport and targeting of proteins to their appropriate locations, explains senior author Dr. Nansi Jo Colley of the UW School of Medicine and Public Health. The complex process is prone to error, and a malfunction in any of the steps can have dire consequences in tissues.

"Accumulation of misfolded proteins often leads to severe pathology and cell death, producing blinding diseases and other neurodegenerative diseases," says Colley, a professor in the Department of Ophthalmology and Visual Sciences, the Department of Genetics and the Eye Research Institute. "Molecular chaperones are one of the first lines of defense in these fundamental processes."

Colley and her team discovered XPORT as a result of screening a collection of 900 fruit-fly mutants that undergo retinal degeneration. The XPORT mutant displayed retinal degeneration and defects in rhodopsin and TRP.

"TRP channels play a vital role as biological sensors, regulating calcium entering cells involved in vision, taste, olfaction, hearing and touch," says Colley, adding that the channels are found in many organisms and tissues. "Defective TRP channels can cause night blindness in certain people."

The first author on the paper, Erica Rosenbaum, a doctoral student in the UW Neuroscience Training Program where Colley is a faculty member, joined with Colley and UW collaborators Kimberly S. Brehm and Eva Vasilijevic, as well as Che-Hsiung Liu and Roger C. Hardie at Cambridge University. Together they identified the mutation and discovered a small novel gene never described before.

They named the protein XPORT, for exit protein of rhodopsin and TRP.

In their experiments, the scientists showed that XPORT forms a complex with rhodopsin and TRP, and is required to successfully transport the two proteins to a specific location on the cell surface. They also determined that XPORT is essential for cell survival mutations in XPORT prevented the two proteins from moving through the trafficking pathway, and this ended in retinal degeneration and blindness in the fly.

XPORT was also found to interact closely with another family of molecular chaperones called heat shock proteins, which are indispensable in the folding of newly synthesized proteins.

"Heat shock proteins have also been implicated as agents that protect nerve cells from degeneration," Colley says, "so XPORT or XPORT-like proteins might have therapeutic potential as well."

While XPORT is an eye-specific protein that is expressed in flies and other insects, Colley expects that a protein very similar to XPORT exists in humans.

The lab works on fruit flies because, as Colley says, "It is an invaluable model system for unraveling the complexity of many neurodegenerative diseases stemming from protein misfolding and aggregation. Studies using molecular genetics in the fruit fly are already greatly improving our ability to treat and perhaps even prevent these diseases."
