Are you eligible for a Lasik surgery?

December 5th, 2009

In order to get clear vision, the eye’s cornea and lens must refract light properly so that images can be focused on the retina of the eye. If the cornea can’t work properly the images become blurry. In this refractive error condition people may need glasses or contact lens to correct vision or a laser surgery. Lasik surgery (short for laser-assisted in situ keratomileusis) is an eye laser surgery that changes the shape of the cornea (the clear covering on the front of the eyeball) permanently by a laser in order to correct vision and eliminate the patient’s dependency on eye glasses or contact lenses. Laser surgery is extremely favored by fashion people who are myopia.

However Lasik surgery is not suitable for everybody, even those with myopia, hyperopia and astigmatism. Comprehensive eye examinations, using a number of medical equipments will be taken and a few questions will be asked before you can undergo laser surgery. First you should be at least 18 years old for Lasik surgery(21 in some cases, depending on the type of laser surgery), since the vision of people younger than 18 continues to change. Your eyes must be healthy to have a laser surgery. The curve of the cornea, the size of the pupils and the thickness of the cornea is measured to determine if there is enough cornea tissue left for a Lasik surgery. Lasik surgery may not be recommended for patients with diabetes, rheumatoid arthritis, lupus, glaucoma, herpes infections of the eye, or cataracts. People who are pregnant or breastfeeding are not recommended for Lasik surgery. After the examinations, the laser surgery doctor will tell you the risks, benefits, possible complications and alternative options, such as PRK and LASEK. After all these, your eye doctor will do Lasik surgery for you.

Cheap Lasik – Is it really cheap?

December 1st, 2009

Nowadays, the average cost of advanced Lasik eye surgeries, which includes the use of Custom Wavefront 3D mapping system and all laser IntraLase, is about $2000. And even the average cost of the cheaper type of Lasik is about $1000. However, it is easy for you to find advertisement on the internet or in the newspapers that some clinics charge Lasik eye surgery for only $699, $499, and even $299. How can it be so cheap? Does it really cheap as we have seen on the advertisement?

We may read carefully about the $299 Lasik eye surgery ads. So the first purpose of the ads achieved. The ridiculous low price is probably aimed to get your attention about the Lasik surgery provided in that clinic. Then go on reading the ads, you may find not this cheap Lasik eye surgery is not for everyone, but only a few meet their requirement, for example the vision of the patient must have -1.25 or better with no astigmatism, which is a minor vision problem that can be corrected with reading glasses from any eye clinics. The reading glasses usually only cost $5. What does that mean if you undergo the Lasik regardless of the truth of the ads? It means you pay $299 for things that $5 is enough.

So finally we understand it is just not a cheap Lasik surgery ads but something looks like cheap which will actually cost you more. The extremely low price is just there to attract your attention. Since eyes are very important to everybody, it is not the things that can be taken for granted. Therefore, it is very important to know more about the eye surgery, from the initial exam to the post care medication and follow up treatments and the process of the Lasik surgery itself, not only the price of it.

Advanced Lasik with Wavefront system

November 14th, 2009

Wavefront system is the most advanced technique available today in Lasik surgery. It is a computer assisted mapping system which is first developed for use on adjusting the optics of the telescopes. Because almost every mirror that is made on earth has abnormalities, which is caused by the gravitiational pull of the earth existing all the time during the process of making mirrors. In order to get a clear picture of the outer space of solar system, the wavefront mapping system is developed to eliminate the effect of all abnormalities of the mirror.

After years of development in the field of astronomy, wavefront mapping system has become a tried technology, and introduced to Lasik surgery. It is now utilized on every type of eye laser surgery today, for instance, Lasik, PRK, LESIK, Epi-Lasik, and IntraLase.

Wavefront mapping system is used in two periods, before and during the Lasik surgery procedure. Before the Lasik surgery, wavefront mapping system is used to exam the eye condition, to judge if the patient is a suitable candidate for Lasik surgery. There is about 6% of the American people is not suitable to undergo a Lasik surgery. Because there maybe a high risk of getting side effect during the surgery due to the bad condition of the patient’s eye, or there is the possibility of not being corrected to 20/20 vision though Lasik surgery. If the patient is a suitable candidate, then the wavefront mapping system can calculate exactly how to reshape the eye for 20/20 vision.

After the initial exam, the wavefront mapping system will be used to guide the laser to reshape the exactly area of the corneal during the Lasik surgery. It makes the process more precise than the traditional ones. Although the wavefront mapping system can give the best possible result, it is important to know that not all patients will achieve 20/20 vision even use this advanced guiding system.
