After ten years’ development, surgical astigmatism treatment is to some extent mature. In particular, LASIK to correct astigmatism has been commonplace and routine. People with over 80% degrees of astigmatism can be treated in the course of LASIK surgery. It is expected that higher degrees of astigmatism can also be corrected with the greater technological advances in the future. In general, astigmatism treatment through LASIK procedure is similar to laser eye surgeries used to correct myopia and hyperopia. The surgeon will alter and remold the shape of the cornea, which performs the majority of focusing power in the human eye.

Differently, LASIK for astigmatism will make the patient’s cornea more spherical, while LASIK for nearsightedness will flatten the cornea. This tells us the basic principle of astigmatism treatment using an eye surgery. In other words, the corneal surface will be more spherical after the surgery. In detail, a special pattern of laser beam will be used to remove certain corneal tissues from only one side. Such a way is aimed to make the cornea more uniform and more spherical. At the same time, this will slightly flatten the cornea, bringing a degree of myopia correction. It requires higher skills in the surgeon if the patient has irregular astigmatism. In general, LASIK for astigmatism correction is safe and keeps high success rates.

The eyes after LASIK procedure should be kept away from any direct touch. The surgeon will create a small corneal flap during LASIK surgery. This flap needs enough time to heal without being moved around. In this case, eye rubbing should be strictly avoided. In addition, LASIK receivers are required to avoid taking a shower on the first day immediately after the surgery or allowing the eyes to get splashed with water. For the well being of the eyes, all water sports should be postponed for at least a week after the surgery. A third instruction is to allow the eyes to get enough rest during the healing period. Ordinary activities such as watching TV, reading, working on the computer and playing video games will actually cause eye strain quite easily. Granting the eyes enough relaxation will accelerate the healing process.

What’s more, the eyes after LASIK surgery should be away from any irritation, damage or unintentional rubbing during sleep. The simplest way is to place a protective patch over the eyes every night during the first week after the procedure. In particular, female patients after laser eye surgery should stop using eye makeup, lotions, sunscreen or any other accessories that may get in the eye. It is suggested that these things should be stopped for at least two weeks. Another important aspect is to diligently apply prescription antibiotic eye drops as well as lubricating drops prescribed by the surgeon. These medications can protect the eyes during the healing process.

In fact, eye problems can be caused by different factors, some of them are related to family history; some to dieting habits; some to reading or using habits; some to eye injuries, etc. On the whole, all these factors can lead to the deformation of cornea and astigmatism emerges as a result. Of course, myopia and hyperopia are two of the most common vision errors among the massive people.

People with myopia can only see clearly of nearby objects, not those in the distance. It has really bothered a lot of people, especially those who often read. However, it can be well rectified if detected at early stage. One of the most widely used ways to treat it is wearing glasses. But the lens may become thicker and heavier as times goes by, when prescription increases.

On the contrary, people with hyperopia can not see clearly of things nearby, but those in the distance. Of course, it is very common among people who are over forty- it is an age related eye problem. For these people, some reading glasses might be suitable. And these glasses should also be well prescribed.

Lasik eye surgery, as its name shows, is a kind of laser-assisted or laser-based eye surgery, in which laser will be used as scalpel. The deformed cornea will be adjusted by the “scalpel” by cutting some extra tissues in the eyes.

And now many people love to receive lasik, for it can bring them a lot of benefits, like get rid of glasses or lenses; save more money in the long run; become much better to look at, etc. However, they should make sure they are good candidates for the surgery first.

If people are good candidates for this surgery, they should spend more time finding a qualified surgeon. This is a really hard job- there are too many to be selected. And one of the best ways is to search online by keying into some key words into the search engines. The information of most eye surgeons can be found there. In addition, people can also read receivers’’ reviews, which are experiences of other people.

To be simple, try to know more about it if people really want to receiver lasik eye surgery.

No doubt that LASIK eye surgery can help us a lot with our eye problems, but this does not mean everybody can be suitable for the surgery. If we want to be a good and qualified candidate for LASIK eye surgery, we should bear in mind the following points:

First, people under 18 are not qualified for LASIK eye surgery. In actual practice, even with parental consent, surgeons also can not perform the surgery. The reason is for people under 18, their eyes are not mature. It is a common case that teenagers often get different prescriptions in eye exams taken at different periods. Their eyes are growing and changing within not long period of time. So surgeons can not take LASIK eye surgery for teenagers under 18.

Second, even for people more than 18 years old, they may also not able to take this surgery. If there is vision change during the past year, it proves that people are not suitable for LASIK eye surgery. So the stable vision state is a premise for taking LASIK eye surgery.

Third, the health state of people can also influence if we can take LASIK eye surgery or not. As we may know, the poor vision may be a symptom of some medical ailments. And if people who have certain eye disease take LASIK eye surgery, other illnesses will affect their vision in their later life. As a result, the LASIK eye surgery will come in vain.

Another concern we care about is the cost of LASIK eye surgery. For most of us, LASIK eye surgery does not mean a small amount of money. As a matter of fact, the cost of LASIK eye surgery varies greatly. The different cost is mainly due to different places, the qualification and experience of the surgeon, the new technology involved in the surgery and so on. Statistics have shown that the price of LASIK eye surgery in the west of the USA is the highest, and in the south of the USA is the lowest, moreover, the price keep increasing in all areas in recent years.

The whole eye exam process is very complex. Eye doctors will first decide whether or not the receivers are good candidates by asking a lot of questions. People in certain eye condition can not wear lenses. After that, an eye check will be operated- this is the same as in eye exam for glasses. The eye doctors will make some observations on the eyes and their structures and reaction to certain drops, etc. After that, the eye condition of the patients can be well detected.

When the patients are proved ideal candidates for lenses, they will receive some examination for lenses. Unlike exam for glasses, this exam is really very complicated and personalized- patient’s eye balls, sizes, and other factors will all be measured in the process. Of course, the whole process is operated with the help of some high-tech equipments, which can accurately measure the sizes and other data.

Later, some other aspects, like how health the corneas are, will all be measured and tested. For example, in order to know how patient’s eyes react to lenses, its moisture will also be measured. And the result is every patient’s contact lenses are completely individualized and can not be worn by others.

After that, when every data is measured, the eye doctor may suggest patients to try on some trial contact lenses. This process is very important, for it determines whether patients can get used to lenses or not. Of course, the trial process is also time-consuming. Usually, people have to try on many pairs until their get the ones fit them most. While trying, eye doctor will also offer some guidance on how to insert and remove lenses. Other suggestions on eye health and lenses maintenance will also be given in details.

When people have brought their lenses home, they should also revisit their eye doctors regularly, until their eyes completely adapt the lenses and they know how to use the lenses. If there is anything unusual, just contact eye doctors for help.

In addition to these healthy habits, cataract can also be sometimes delayed by consuming enough antioxidants including vitamins. There are study results suggesting that higher risk of getting cataracts always occurs in individuals with low blood level antioxidants and those who have inadequate intake of foods and vegetables that are rich in antioxidants. From another perspective, cataracts can be delayed by supplementing the body with antioxidants and vitamins. The reason lies in that free radical’s damage to eye cells can be neutralized by antioxidants.

Vitamin C is an important member of antioxidants which functions quite well in cataract prevention. In addition, taking enough vitamin C is also effective in preventing macular degeneration. In general, a daily dose of over 300 mg is suitable. Vitamin E has also been found to play a similar role as vitamin C. Besides these beneficial vitamins, beta carotenoid is also a powerful antioxidant that is beneficial in cataract prevention. Foods like carrots, pumpkin, papaya and tomatoes are rich in beta carotenoid. Other substances for cataract prevention include lycopene and riboflavin.

Non-infectious pink eye even has other causes, including chemicals such as chlorine and soaps as well as environmental substances such as smoke and fumes. Unlike infection pink eye, non-infection pink eye has symptoms such as tearing, itching and soreness. The most significant difference may be that it will not be transmitted to another person.
