There are many different types of vision problems. The most common types are: short-sightedness (myopia), long-sightedness (hypermetropia), and astigmatism. Regardless of the type of vision problem to be treated, the same type of laser, referred to as an excimer laser, is used during laser eye surgery.

The Types of Laser Eye Surgery

There are four main types of laser eye surgery:

Photorefractive Keratectomy (PRK)

PRK has been carried out by surgeons since the late 1980s yet since the development of new techniques, such as LASIK and LASEK, PRK is now mainly used for the correction of a low degree of short-sightedness. In PRK, the cornea is reshaped with the help of an excimer laser. However, a flap of corneal tissue is not cut during this procedure.

Laser in Situ Keratomileusis (LASIK)

LASIK has been carried out since the mid-1990s. The majority of types of refractive error are able to be corrected through LASIK. However, the procedure may not be suitable for the correction of a high degree of short-sightedness. During LASIK, surgeons make an incision across the cornea and create a flap of tissue. This tissue is then raised and the exposed surface reshaped with the excimer laser. Following laser treatment, the flap is replaced. A typical LASIK eye treatment lasts around four minutes in duration.

Laser Epithelial Keratomileusis (LASEK)

LASEK is not dissimilar to PRK. However, the surface layer of the cornea, known as the epithelium, is retained as a flap. This retention of the epithelium is believed to prevent complications following surgery and may also reduce healing times.

Wavefront-guided LASIK

Wavefront-guided LASIK lessens the eye’s natural irregularities. These irregularities can cause the insufficient focusing of light rays and can hence improve vision following surgery.

Patients considering laser eye surgery should consult with their eye surgeon to determine the best way in which to correct vision, and the benefits and drawbacks of the use of eye glasses, contact lenses and laser eye surgery.

The Risks of Laser Eye Surgery

The complications of laser eye surgery occur in fewer than five percent of cases. Patients wishing to undergo laser eye surgery will find that their chosen surgeon will discuss the risks of treatment with them.

Some people who undergo laser eye surgery may experience problems with dry eyes following surgery. Artificial tear supplements may therefore be required following surgery to prevent dry eyes. Many patients who have just undergone laser eye surgery will experience glare or halo effects when they are operating a vehicle during the night. This halo effect is increasingly likely to occur if a high degree of short-sightedness or long-sightedness has been corrected with surgery. The effect is usually only temporary and is rarely severe.

In rare cases, surgery can cause thinning of the eye wall. This can render the shape of the eye relatively unstable following treatment. Severe vision loss following surgery is very unusual. However, patients who experience vision loss may require further surgery to help to restore their vision. Alternatively, they may require the use of hard contact lenses.

Why Shampoos Have Sodium Chloride
Shampoos have sodium chloride because this is the component that thickens the mixture if the main surfactant is sodium lauryl sulfate. Surfactants trap oily materials from the surface and separate it from the rest of the hair strands. This allows the shampoo to strip off the dirt and grime that coat your hair at the end of the day. The problem with surfactants is that they can be harsh. The same kind of detergents used in shampoos is similar to those used in toilet cleaners and industrial cleaners, which means that they are formulated to remove strong oil or petroleum based grime and stains, which you will not likely find in human hair.

Shampoos contain sodium lauryl sulfate because it is cheap. This detergent costs a few pennies per jar, which makes it an affordable option for shampoo companies. However, it is cheap for a reason. Sodium chlorideΓÇôcontaining shampoos are very harsh and are often the causes why people have brittle and thinning hair.

Reasons to Choose a Sodium Chloride-Free Shampoo
Shampoos that do not contain these harsh detergents often keep the natural oils intact while removing dirt and grime. The result is softer and healthier hair that is able to keep its natural shine. In most cases, these shampoos are often cheaper compared to regular shampoos and tend to be healthier for the scalp as well. People who switched to organic shampoos that contain no sodium or sulfates tend to experience less hair fall and their hair is less prone to breakage. The shampoo may not lather too well during showers, but the same amount of dirt is removed and hair is left clean and fresh.
There are so many reasons why sodium chloride free shampoo is the better alternative especially if you want to reduce the amount of chemicals you are putting on your body. This type of shampoo is not harsh and will not destroy the delicate balance of oils in your hair. With shampoo free from harsh detergents you can be sure to enjoy healthy and shiny hair without any major hair fall or breakage.

One of Dean’s most famous creations is the five in one cleansing conditioner that can take the place of shampoo, conditioner, deep conditioner, detangler and leave in conditioner. This cleansing conditioner can be used in a single step to cleanse the hair or as part of a cleansing and styling regimen. On its own, it provides sheen, manageability and moisture to the hair and also gives better color retention to color treated hair. Furthermore, it does not strip the hair and scalp of their natural oils and minerals, which contributes to hair damage.

In addition to the cleansing conditioner, there are other products that contribute to the hair care regimen. For instance, the styling creme not only further adds to the moisture and sheen properties of the cleanser but also adds body and helps further manage the hair issues like split ends and frizz. Those with extremely damaged hair can help restore and strengthen their locks with the re-moist intensive hair mask treatment that also can contribute to the sheen, moisture and body of the hair.

For further skin care, WEN products for the body can nourish the skin. These products include the treatment oils that can be used for the hair, scalp and skin. The replenishing treatment mist not only restores dry, frizzy or dehydrated hair but also refreshes the face and helps set makeup. Also, the treatment oils can be used on their own or combined with the bath salts to help rejuvenate rough areas of the skin including dry elbows, heels and knees.

Dean also has a few other products that can aid in the hair care process such as the Spornette brushes in round boar or paddle designs. There are also the trademarked deluxe round boar bristle brush and saw-cut shower comb. Soy candles in a variety of sizes are available in scents such as cucumber aloe, fig, lavender, sweet almond mint and tea tree. Other products including the hair care and skin care products are also available in scents and in different sizes.

Although Chaz Dean is known for his advances in the beauty industry, he is also noted for the products he creates for the skin as well as for the home to keep the spirit calm. Made with natural ingredients, these products are not only good for the hair and skin but also do as little damage as possible to the environment. With his WEN products, Chaz Dean has shown that healthy products are best for healthy hair and skin.

Dealing With Hair Loss And Breakage

Damaged hair breaks easily and this can be extremely difficult to deal with, especially for women. As many women age they will often find that in addition to regular hair breakage they are also seeing an increase in hair loss. This commonly results from changes in hormones, diet and self-care products. In order to enjoy a truly healthy scalp and vibrant lovely hair at every age, these individuals seek out natural ingredients that will nourish their hair from root to tip, preventing breakage and scalp-related hair loss.

Increased Hair Growth

Many of the beneficial ingredients that a natural shampoo typically contains are intended to increase the health of both the scalp and the hair follicles. For those seeking longer, more lustrous and healthier hair, these additions are essential for restoring optimal health to these areas. Many of the herbal extracts that are commonly included in these formulations are even able to strip away build-ups that are caused by the regular or excessive use of styling products. This feature is especially beneficial for people who use oil-based or petroleum-based moisturizers, which can with time have a damaging impact on the scalp and hair follicles. Thus, not only do all-natural formulations help to encourage new hair growth, but they can help reverse the damages caused by other products, such as clogged hair follicles and dry, damaged scalp. This too, will allow for an increase in growth and overall scalp and hair health.

Reducing The Risk Of Allergic Reactions

Many of the big name shampoo brands are known to cause adverse effects in people who are sensitive to certain chemicals. For these individuals, using popular products often means having to suffer from itchy, dry scalp. When hair loss is an issue due to unhealthy scalp conditions, highly chemical formulations will only serve to compound the problem. Products that promise to be both rich in nutrients and in moisture, may actually detract both nutrients and moisture from areas where they are most vital. Thus, even while the hair may feel healthy, silky and utterly pampered by a conventional shampoo product, the scalp may be suffering intolerably. A natural shampoo that contains soothing and calming ingredients will ultimately restore health to the highly sensitive skin on the pate, allowing it to produce the proper amounts of natural oils for creating a strong head of hair.

It should not be forgotten that one major benefit of switching to a natural shampoo is the ability to use a product that has a very minimal impact on the environment. Few women miss the days of hair sprays and other aerosol beauty products that released harmful CFCs into the ozone. Now, however, women are growing increasingly concerned over the impact that chemical formulations are having on local water supplies as well the ecological disadvantages of using beauty products that are not biodegradable. Natural cleansers do not have a significant negative impact on the earth or the human body, thus, people can use them without fear, worry or guilt. Because all of the included ingredients in the best of these products are nature-derived, people can enjoy more moderate fragrances and aromas, fewer to no allergic reactions and all of the nutrients for great-looking hair without the disadvantages of harmful chemicals.

Diagnosis

It is important not to mistake this skin affliction for some other rash with a different cause. Psoriasis and heat rash are occasionally mistaken for eczema. Doctors can verify that the underlying cause is eczema by considering the timing of the rash, the pattern of its flare ups and the reaction of the patient and the patient’s body. The typical locations for this rash are on the forehead, the cheeks and at any of the locations on the body that have creases or folds, such as at the elbow or the knee.

Prevention

Since there is no real cure for childrens eczema and many treatments can cause discomfort, the best thing to do is to prevent outbreaks as much as possible. Many things are considered to be triggers of eczema flare-ups. These include certain soaps, harsh fabrics such as polyester or wool, dust mites, overheating, food allergies and dehydration. For this reason, it is important to remain aware of your child’s environment at all times. He or she should not be overdressed, should drink plenty of water and keep skin moisturized.

To maintain the proper balance between dry skin and over moisturizing, give the child daily baths in tepid water. Either avoid soap or use a very mild brand that you know will not have an adverse effect on his or her skin. Always apply moisturizer after drying him or her with a soft towel.

Treatment

Inevitably, no matter how careful you or your children are, the eczema will flare up. There are three primary ways to respond to these incidents. These include topical applications as well as drugs.

” Topical steroid applications are available in pharmacies as over-the-counter products. You have an assortment from which to choose. They vary in strength. However, these products can also have side effects which may be worse than the eczema, particularly if they are used too long. Never apply these steroids to your child’s face or under diapers or other tight-fitting applications.
” There are now available other topical medications which do not include steroids in their ingredients. They are called immunomodulators. They are recommended for children above the age of two. Remarkably, they can actually deter a severe flare up if they are applied at the first sign of a recurrence.
” Antihistamines are also helpful. Most of all, products containing antihistamines can help your child sleep when the itching is bad. This is important because childrens eczema will only become more irritating if you and your child are also deprived of sleep.”

Signs of Radiotherapy Skin Damage
Signs of skin irritations manifest according to three levels of severity. In patients who manifest first-degree reactions, the affected areas are often red and dry. Sufferers may complain of an itchy sensation on the affected area. The discoloration only often affects the areas treated, so the discolorations may appear as patches of red. Bright red discolorations, a burning sensation, and blisters characterize second-degree reactions, and these are more painful than first-degree reactions. The third degree reaction is the most severe. Sufferers often manifest open and moist skin lesions, which are painful and weepy. Patients who are expected to undergo long periods of radiotherapy treatment often have the highest risk of developing third degree reactions. Areas where these reactions can be commonly found include all areas which skin folds are present, such as the skin fold under the breast and around the nipples, the neck, armpits, right below the glutes, and the groin.

Patients at Risk for Radiotherapy Skin Damage
Patients whose skin integrity is compromised due to age or illness are especially prone to radiotherapy damage. The skin of elderly patients is no longer capable of rapid regeneration of new skin cells so discolorations and burns may take longer to heal. Patients suffering from immune system conditions may also be more prone to developing infections because of skin damage.

Treatment for Radiotherapy Skin Damage
Damage and wounds resulting from radiotherapy can be treated using topical creams. Acute reactions such as discolorations can be treated using anti-itching products that reduce the itchy sensation to prevent the sufferer from scratching on the affected area. Anti-itching medications prevent the patient from scratching and breaking the skin, since this can easily lead to infections. For cancer patients with compromised immune systems, the slightest infection can be fatal.

For open sores that develop into infections, patients are often given antibiotics to stop the proliferation of bacteria. Antibiotics are extremely important in making sure that existing infections are treated before the patient’s immune system shuts down. Patients may also be advised to use moisturizing creams designed to prevent rashes and irritation caused by radiotherapy. This will lessen the risk for the development of first or second-degree reactions later on.

Radiotherapy skin damage is painful and often the precursor to more serious infections when not treated right away. It is therefore important to look for early signs of skin irritation and damage after every radiotherapy treatment. Very sick patients need to boost their immunity using diet and medications in order to lessen their chances of developing the side effects of the therapy, which could easily lead to fatal infections.

History of Eye Surgery

Surgeons have been able to operate on the eyes successfully since the middle of the 20th century. A metal knife known as a microkeratome was used to cut the cornea open and excise portions in order to have an effect on the vision. This procedure could be effective but it obviously had the drawback of causing pain in the patient due to the inherent discomfort of having a knife scrape at your eye. For this reason, surgeons actively looked for ways to make the surgical process easier on the patient.

In the 1980′s, a doctor finally patented a procedure that used lasers to improve vision by carving the cornea just as surgeons had previously done with knives. In the following decade, this method gained acceptance and was lauded for the short amount of time required and the relatively small amount of pain caused. In the first decade of the 21st century, a computer-aided version of this procedure began to allow doctors to do more than simply fix a patient’s vision. The wavefront technique can actually make some patients see better than normal and give them 20/10 vision or better.

Steps To Laser Eye Surgery

” The patient stops wearing contact lenses for a certain period of weeks prior to surgery. Each doctor will explain the specifics to patients, depending on the type of lenses that they wear.
” The patient arrives at the doctor’s office or other surgical center just prior to the surgery. The surgical team will use a special device to map the patient’s cornea for reference during the surgery.
” The patient self-administers anesthetic drops in his or her eyes right before lying down for the surgery.
” A member of the surgical team applies a corneal suction ring to the eye on which they will be operating. This holds the eye still and diminishes interference from the eye lids.
” The surgeon turns on the laser and quickly cuts the cornea and folds it down, leaving a hinge at the bottom and essentially turning the cornea into a flap.
” With the middle cornea exposed, the surgeon cuts away material and alters the shape of this part of the eye as is necessary.
” The surgeon checks for debris, moisture and air bubbles before closing the flap. There is no need for suturing as this incision will close and heal on its own over the course of weeks.
” Afterward, the patient, who has remained awake the entire sixty seconds that were required for cutting, will receive anti-biotic eye drops. The only precautions that he or she will have to follow regard bright lights and sunglasses. The eye will heal on its own and soon be working better than it did prior to the laser eye surgery operation.”
