A Cure for Near Sightedness – Radial Keratotomy

Radial keratotomy (RK) is a refractive surgical procedure employed to correct myopia or nearsightedness. Radial Keratotomy came into existence by accident rather than through meticulous research. The procedure was discovered by Dr. Svyatoslav Fyodorov when he operated one of his patients who had met with a bicycle accident. The boy wore eyeglasses, which broke on impact, and the glass splinters lodged into his eyes. The doctor had to make several radial incisions in the corneal tissue in order to extract the glass. When the cornea healed, the doctor found that the boy’s eyesight was significantly improved.

In radial keratotomy (RK), a series of micro-fine incisions are made in the outer portion of the cornea with the aid of a high-precision calibrated diamond knife. The surgeon administers a local anesthetic, since the incisions are superficial and the procedure is fairly painless. The corneal thickness of the patient’s eye is measured prior to the surgery. Before the incisions are made, the diamond-edged cutting instrument is precisely set under the operating microscope. Thus by flattening the curvature of the cornea in such a manner, RK can easily correct myopia or nearsightedness.

Radial keratotomy was first introduced in the United States in the 1980s. Initially it was much of an investigational procedure, with doctors operating only one eye at a time and waiting for at least 3 months to observe the results, before operating on the other eye. But the surgeons gained experience over time and now they could well operate both eyes simultaneously. Now, radial keratotomy is a minor surgery that takes about 15 to 20 minutes for each eye.

Radial keratotomy is constantly improving, owing much to the rapid advances in technology, and the fact that a number of such procedures have already been performed successfully. However, RK is not as precise as LASIK and PRK. Since, RK is less predictable, only a few surgeons now perform this procedure.

Astigmatism – Cause For Blurred Vision

It is one of the main reasons for having blurred vision which many people are not aware of. It is stated to be one of the common reasons for having eyesight problems. This condition brings nearsightedness or farsightedness along with it.

It is caused mainly due to irregular shape of the cornea or of the lens which is located behind the cornea and is called as lenticular astigmatism. The problem can be corrected by use of eyeglasses, contact lenses or refractive surgery.

To put it in lay man’s term astigmatism means that the cornea is oval in shape instead of being spherical. The cornea in the astigmatism condition has two curves – a steeper and a flatter curve. This kind of curve spreads the light to two focus points instead of one, leading to blurred vision.

Astigmatism is said to be hereditary as many are born with oblong cornea. Being born with this defect can create problems for future. Astigmatism is also caused due to scarring of the cornea by performing certain type of eye surgery. It is also caused due to keratoconus – a disease which causes thinning of the cornea.

Astigmatism leads to nearsightedness (myopia) when the cornea is curved too much. The light which should be focused on the retina is focused in front of the retina leading to a blurry vision for distant objects. It also causes farsightedness (hyperopia), as the cornea is not properly curved. Here, the light is focused behind the back of your eye making nearby objects blurry.

You can detect the signs and symptoms of astigmatism when there is deformation in parts of the visual field. The horizontal, vertical or diagonal lines look blurred. It may seem to do less harm to you but if this condition worsens it is better to consult your doctor. If you are suffering from blurred vision or headaches, a doctor’s consultation is very important. Rubbing or squinting is also a good sign to confer with your doctor. By practicing yoga the problem of astigmatism may lessen.

One of the most common types of surgeries used to correct astigmatism is the astigmatic keratotomy and LASIK. This kind of surgery reshapes the cornea which makes it right enough to focus on one point. The one thing that can be done to correct astigmatism is to get a surgery done as early as possible. Children are at risk to permanently loose their eyesight due to astigmatism. So the best solution for this is an early surgery.

Bilberry Fights Night Blindness And Other Diseases

Over centuries bilberry has been used for its medicinal purposes. Similar to blueberries and cranberries, bilberry also contains anti-inflammatory and anti-oxidant qualities. This fruit is used for its astringent, tonic and antiseptic properties which can treat various health problems like diarrhea, dysentery, hemorrhoids and gastrointestinal inflammation. The most important use for bilberry has been the treatment of various eye disorders and improvement of capillary health.

Bilberry has been very effective in improving night vision. Being a close relative of blueberry, it contains high levels of natural antioxidant compound. These antioxidants prevent free radicals from causing any damage to the eye. It also strengthens the small blood vessels that carry oxygen to the eyes.

Bilberry is high in flavonoids known as Anthocyanosides, that quickens the regeneration of Rhodospin, a purple pigment used as rods in the eye for night vision. It is also useful in treating macular degeneration, diabetic retinopathy and cataract. One study has shown that combination of bilberry extracts and vitamin E reduces the progression of cataract.

Studies have shown that supplementation with bilberry improves eye adaptation to darkness for people with poor vision. It does not work with people having good vision though. Bilberry extracts are known to improve the functional ability of eyes and other organs. It is also useful in treating bruising, general subcutaneous bleeding, and easing inflammation that occurs in osteoarthritis, rheumatoid arthritis and gum disease.

Bilberry leaves can be used to treat diabetes due to its hypoglycemic properties. It can be used as a topical treatment in the form of infusion or decoctions, like tea or liquid extracts for eyes and mouth inflammation, skin infections and burns. It is known to treat chronic venous insufficiency, varicose veins, pain, itching, and skin ulcers in the legs. It may also prove be effective in treating Raynaud’s disease.

It can be useful in treating atherosclerosis as it strengthens artery walls and promotes good circulation. Eating bilberry mixed with honey is a popular home remedy for diarrhea. It is also very effective in curing and treating peptic ulcers, fibrocystic breast disease and painful menstruation. It is available in tincture as well as capsule form. And fresh bilberries are always there to be plucked.

To reduce cataract, macular degeneration and other eye problems take 80-160 mg of standardized extract or 1/2 teaspoon liquid extract two or three times a day. For diabetic retinopathy take 80- 160 mg (standardized to 23-37% anthocyanosides) at least three times a day

To treat varicose veins consume 80-160 mg standardized extract three times a day.

For sore throat and diarrhea make bilberry tea by pouring 1 cup hot water in 1 or 2 tablespoons of dried whole berries (or 2 to 3 teaspoons of finely crushed berries). Strain and drink at least 4 cups a day.

In some individuals consumption of bilberry internally may interfere with iron absorption. Lactating and pregnant women should avoid it, completely.

Contact Lens Update: How To Avoid Fungal Eye Infections

Earlier this year, contact lens wearers around the world got a scare when news of an outbreak of an eye infection called fungal keratitis came out. This fungal eye infection can be treated relatively easily if caught early, but more established cases may lead to a need for a corneal transplant or worse, loss of the affected eye.

According to the Centers for Disease Prevention and Control (CDC), as of May there had been 130 confirmed cases of fungal eye infections in the US in a one year period and of those cases, all but 5 were in contact lens wearers. 37 of these people have required corneal transplants. Bausch and Lomb’s ReNu with MoistureLoc contact lens cleaning solution has been blamed by some for the outbreak, since 76% of contact lens wearers who contracted fungal keratitis used that particular solution, while it holds only a 10% market share in contact lens cleaning solutions. The product has since been pulled from the market while investigations continue. The consensus seems to be that the fungus is not present in the solution itself, but rather that it forms a film in contact lens cases that prevents disinfection of the case. The fungus itself, Fusarium, is quite common and can be found in water, soil, and plants, so could easily end up in contact lens cases that are not properly disinfected. There have been cases in Europe and Asia as well, and links to ReNu products there are being investigated.

There are several steps that soft contact lens wearers can take to protect themselves from fungal eye infections, many of which they should be doing already in routine proper care of their contact lenses. First, if people have any of the ReNu with MoistureLoc solution, they should stop using it and throw the rest away. Second, follow basic hygiene good sense, like washing your hands before you touch your contact lenses. Clean your contact lens case thoroughly, store it where it will not get contaminated, and replace it periodically. There are new lens cases available that are made with antimicrobial agents to prevent contamination. Don’t mix old and new cleaning solution, and don’t wear lenses longer than their prescribed schedule.

If you are afraid you may have a fungal eye infection, seek help right away. Symptoms include blurry vision, clouding of the eye, loss of vision, excessive irritation, discharge, lesions on the eye, and new sensitivity to light.

Dry Eye Syndrome – A Problematic Eye Condition

Dry Eye Syndrome is a very common phenomenon causing lots of problems to millions of people all over the world. It is caused due to the deteriorating quality of the tear lining. A physically fit and healthy eye would be covered by a tear film. It is that fluid which remains between the blinks making your eyes wet.

The tear lining helps to keep your eyes free from infection and bacteria. It gives the eye a clean and clear vision without any irritation. The tear lining removes the dirt and any other dust particles that cause friction in your eyes.

When the productivity of fluid from your tear glands gets lessened, it leads to irritation and dry spots on the cornea – a reason for a weakened vision. It can easily be induced by various polluting factor in the environment.

Old age is also one of the factors leading to dry eye syndrome. Due to the increasing age factor our body produces less oil resulting in less fluid production. A very common phenomena among women who tend to have drier skin than men. This oil deficiency affects your tear film.

You can keep an ‘eye’ on certain signs and symptoms, which can be easily detected if suffering from dry eye syndrome. Itching, burning, irritation, redness, tiredness of eye, mucus surrounding your eye and many more can are the known signs.

A diet which has borage oil, grape seed oil, primrose oil, soybean oil, whole grains can be very useful to avoid dryness in your eye.

Omega 3 can be found in cold water fish like salmon, mackerel, sardines and herring. Fresh vegetables, flaxseeds, walnuts and canola oil would help to prevent any dry eye syndrome.

Growing Number Of Parents Urging Contacts-Wearing Kids To Have LASIK Vision Correction

It’s normal for parents to be concerned about their children’s health and well-being. But Tammy Crane, mother of 21-year-old Garrett, took a more active route-something she could do for her son that would have both of them worrying less. She had Garrett get rid of his contacts by having LASIK.

“Garrett’s broken his glasses several times and, of course, he always wants the latest designer glasses. He would go through contacts like water,” says Tammy.

Ophthalmologists are seeing growing numbers of parents encouraging their young adult children to have LASIK. One reason is the monetary savings. Contacts cost up to $600 annually, and glasses can run upwards of $1,200 a pair. Considering that male eyes stop “growing” at age 21 and female eyes at age 18, young adults having LASIK in their early 20s will recoup their costs well before they hit their 30s. Additionally, the procedure can last for up to 30 years, making the cost savings of LASIK as compared to contacts and glasses significant-well into the thousands.

Tammy was so pleased with the results of her own LASIK procedure that she knew she wanted the same for her son. “I had LASIK four years ago and knew what a blessing it was,” she says. “I knew if Garrett had it now, he could get even more years of enjoyment out of it. I also knew he didn’t take proper care of his contacts and with the recent breakout of fungal infections, I was worried.”

Among the other LASIK benefits parents find appealing is that they no longer worry about the risks associated with their children’s poor contact lens hygiene.

“Garrett told me of different times when he had stored his contacts in glasses of water. And the outside of his case was disgusting. He never changed the solution,” Tammy says. “In fact, he had a few minor infections over the years due to his poor contacts care.”

For Tammy and Garrett, they insisted on the most advanced technology available-LASIK with the IntraLase Method. Dr. Daniel Durrie, who did Garrett’s procedure, commented, “Patients who have this advanced LASIK method generally achieve vision better than 20/20. Additionally, LASIK with the IntraLase Method is blade-free, meaning patients avoid the most serious and sight-threatening complications associated with the traditional metal blade.” The safety advantage of the IntraLase Method has given parents such as Tammy the confidence to allow their children to have LASIK.

Today, Garrett enjoys a contacts-free lifestyle that includes his favorite hobbies, such as canoeing and jet skiing. “It’s awesome,” he says. “I opened my eyes underwater and could see. It was pretty cool.”

Parents worried about infections and costs urge kids to have LASIK with the IntraLase method.

Information On Eyelid Surgery

Eyelid surgery, also called blepharoplasty in professional medical language, is a cosmetic procedure during which excess fat and skin along with the muscle is removed from the upper and lower eyelids.

Dropping upper eyelids and puffy bags under your eyes can make you look older than you really are. The effects are due to the aging process and are caused by excess fat and skin around your eyes.

Dropping upper eyelids and puffy bags under your eyes may not only change your appearance and cause some psychological problems but also may interfere with your vision. Puffiness of lower lids cannot be improved with the application of any cream or other skin care products. This problem can only be solved with the help of eyelid surgery.

Eyelid surgery is generally performed on adults, who through the natural aging process have lost the elasticity in the skin around their eyes. An eyelid reduction removes the surplus skin and fat to produce a more alert appearance and reduce morning swelling.

As people get older their bodies change. These changes are associated with many reasons and aging is one of the most important reasons of all. Eyelid surgery is one of the corrective procedures that are able to improve people’s appearance and make them feel better about how they look.

The eyes are the windows to the soul as the old saying goes. If your eyes look great you look great. Our eyes make the first contact whenever we meet with someone. Well-toned clear skins of the eyelids are of crucial importance for overall beauty. Eyelid surgery can usually eradicate the problems, however in some cases additional procedures may be necessary in conjunction with this surgery. Your surgeon will make a thorough assessment of your individual requirements and advise you accordingly.

Incisions are made in natural creases in your both upper and lower eyelids so that they can’t be easily noticeable after recovery from surgery. The tender skin around the eyes is more vulnerable to frequent expression leading to the ‘wrinkles’ that tends to become deeper in this area. If you wish to minimize them, a laser treatment can be employed in this area during your surgical procedure.

If you are going to have a general anesthetic and are a smoker you will be asked to stop smoking before surgery to prevent any unnecessary complications. Some analgesics like aspirin and even some anti-inflammatory drugs should not be taken prior to eyelid surgery as a safety measure.
