If you are dependent on glasses or contact lenses, you may wonder if laser eye surgery is an option for everyone. Many people today are rushing out and finding an eye surgery so they no longer have to wear corrective lenses, however, if you are not a good candidate for the procedure you may soon learn that the complications are not worth the risk.

Before you make that decision, you should look at everything that is involved including the number one thing to know. Is the eye doctor licensed to perform laser eye surgery? There are not as many licensed ophthalmologist as you might think. Ask to see the certificate to ensure they know what they are doing and learn how many times they have performed the procedure. It would also be in your best interest to find out how many times they have performed the procedure with blades and without blades.

Learn what risks are involved and if your own expectations will be met with laser eye surgery. Many people that have this procedure learn that they still have to wear glasses for night vision among a few other vision problems. Just because this procedure helps you to see clearer, does not mean that you will have 20/20 vision. Be prepared for less than perfect vision.

Laser eye surgery is expensive; however, if you divide it out over the years it will amount to less than purchasing glasses or contacts each and every year. Talk with your insurance carrier, in some cases; they will cover part of the costs.

Individuals under the age of 18 cannot have laser eye surgery. The eyes are still developing and do not have refractive stability yet. Pregnant women, breastfeeding mothers, persons with diabetes, or those taking medications that cause variations in vision are not good candidates for this procedure.

The best way to learn if you are a good candidate is to discuss this with your health care provider before you visit your eye doctor or ophthalmologist. Individuals that have conditions such as shingles or herpes around the eyes should give this important information to the eye doctor as well as any other health problem associated with the eyes such as any eye disease, ocular hypertension, glaucoma, keratoconus, or other eye surgeries.

Just remember, laser eye surgery is surgery! With all surgeries, even elective surgeries there can be complications such as infection and other diverse reactions. The best thing to do is to discuss your expectations and your concerns with your doctor and your ophthalmologist.

For those of us who deal with the ramifications of less than perfect vision on a daily basis, we know how much our routines can center on maintaining our eyewear; from uncomfortable glasses that get in our way, to contact lenses that dry our eyes and always seem to go missing at the most inopportune moments. And when you add to that the expense of vision treatment for those who wear glasses or contacts, it can be downright frustrating. But what most people have come to discover is that corrective laser eye surgery - a procedure that takes less than an hour and costs considerably less than a lifetime of vision correction prescriptions - can not only perfect your vision but address a number of eye conditions with which many people suffer.

Corrective laser eye surgery can allow you to finally have the vision you have always wanted; most patients are able to achieve 20/20 vision even immediately following the procedure. For those who have suffered with poor vision their entire lives, this can be a miracle procedure. And for those who suffer from such degenerative conditions as dry eye - wherein sufferers experience itchy, burning eyes, glaucoma, cataracts, and macular degeneration, corrective laser eye surgery can be a saving grace.

When most people think of corrective laser eye surgery they immediately think of Lasik surgery - a popular procedure that is used to correct vision. But the truth is that corrective eye surgery is rather like an umbrella phrase under which all manner of corrective procedures fall. Lasik is indeed one of the procedures that falls under this umbrella and is considered to be an excimer laser procedure - through which the cornea of the eye is reshaped by laser. Lasik - and the procedures like it - correct nearsightedness, farsightedness, and astigmatism. The difference between the various excimer laser procedures is the type of laser that is used and the technique that is followed depending on what particular procedure is likely to bring you the most success based on the condition and shape of your eyes.

Non-excimer laser procedures are another group that falls with corrective laser eye surgery. Such procedures involve one of three things: the insertion of permanent lenses into the eye, the reshaping of the eye using laser energy or radio waves instead of lasers themselves, or the actual cutting of the eye. These procedures are meant for those who experience severely compromised vision or cataracts.

Other corrective eye surgery may include more complex and comprehensive procedures such as cornea transplants during which healthy tissue from a donor eye is transplanted into the eye of someone whose own cornea has been compromised due to injury or illness. There is also a procedure that is used to treat Keratoconus - or the bulging of the corneas; during this procedure the surgeon places plastic inserts (Intacs) onto the corners of the cornea to flatten them.

Not surprisingly, as technology continues to advance, corrective laser eye surgery continues to make similar advancements. More and more people have come to discover that it is no longer necessary to live with permanent vision impairment. If you feel that you may be a candidate for such procedures, see your eye doctor for a thorough examination.

VISX Star 4

VISX Star 4 is the fourth Excimer laser from VISX approved for use in LASIK corrective vision surgery. With the addition of the CustomVue treatment using Wavefront technology, VISX Star 4 is among the most accurate surgical lasers in use today. Wavefront technology is VISX’s diagnostic tool for accurately measuring the shape of the corneas. Using Fourier transform algorithms, the Wavefront system creates a very accurate model of the cornea and the reshaping necessary for complete vision correction. According to VISX, over 94% of the population needing vision correction for hyperopia (farsightedness) or myopia (nearsightedness) can get completely accurate vision correction with Wavefront-guided VISX Star 4 laser treatment. The VISX Star 4 laser then ablates the cornea according to the model constructed by the Wavefront software. In addition, the Wavefront software models how patients see point sources of light to minimize the glare and fuzziness people sometimes see when driving at night after LASIK treatment.

The only real down side of the VISX system is that it does not correct vision for patients with higher-order aberrations, which can cause vision problems such as glare and halos, and for high myopic astigmatism, the astigmatism actually increased following CustomVue treatment.

LADARVision

LADARVision is another brand of Excimer laser approved by the FDA for LASIK laser vision correction. As a counterpoint to VISX’s CustomVue treatment, LADARVision offers CustomCornea. Similarly, LADARWave is a cornea-mapping system similar to Wavefront in all respects. LADARVision treats all forms of vision defects treated by the VISX Star 4 laser, with the addition of higher-order aberrations. While the VISX system has been shown to be either ineffective or harmful for higher-order aberrations, the LADARVision system has been approved to treat these deviations from perfect vision.

Bausch & Lomb Zyoptix Technolas 217z

Bausch & Lomb’s Zyoptix system purports to be a personalized vision correction system. The system measures the imperfections in the eye and comes up with a precise, computer-controlled laser to ablate the surface of the cornea, providing 20/20 or better vision in 91.5% of all patients. Like the LADARVision and VISX system, the Zyoptix system has an eye-tracking routine that prevents the procedure from being impaired by the reflexive eye movements of the patient. It is also approved to treat higher-order aberrations, like the LADARVision system. Recently, this system was also approved for use in treating mixed astigmatism.

Of these three lasers most commonly used for LASIK treatments, then, it seems the only one that suffers from any significant defect is the VISX system, and then only if you are suffering from higher-order aberrations in your cornea. When you consult with your ophthalmologist about your LASIK treatment, make sure and ask him or her about higher-order aberrations and make sure you are receiving a treatment than can address your particular vision problems.

If it works, the laser treatment could eliminate acne permanently by partially destroying the troublesome glands. Years ago when lasers were suggested as a form of treatment for acne, the results were not as good as dermatologists wanted. The advancement of laser treatment and technology has brought therapy into the new century and is the suggested treatment for acne and acne scarring. When an acne patient faces pitting, or deep holes, in the skin as a result of acne, there is a treatment called laser resurfacing. pages you find information on acne laser treatment, including the different types of acne, and how … I have not tried the new laser treatments for acne, but hear they do not work very well.

Near infrared (NIR) diode laser low-intensity (soft) phototherapy with the topical application of indocyanine green (ICG) has been suggested for treatment of acne vulgaris. Acne scarring, formerly treated with excision and dermabrasion, has benefitted from newer alternatives, such as fillers and non-ablative laser treatments. The prinicpal advantage of laser and light-based treatment of acne is safety. Whether or not laser treatments should be used as first-line treatment for acne, or even for prevention of acne, remains unclear at this time.

Any vision that is already lost prior to the laser treatment, in general, will not return. In general, loss of vision after a laser treatment is usually FROM progression of the glaucoma disease and not FROM the laser per se. However, the immediate vision loss caused by laser treatment must be measured against the more severe vision loss that could result from untreated retinopathy. However, the vision loss caused by laser treatment is mild compared with the vision loss that may be caused by untreated retinopathy. Following the laser treatment the vision is quite blurred for about a week and after that vision largely recovers. Some people will notice decreased side vision or decreased night vision after laser treatment to stop bleeding. Therefore, floaters or spots in your vision will not necessarily go away after laser treatment.

Immediately after the laser, your vision will be blurred because of the bright lights and jelly used for the special laser treatment lens. Peripheral, color or night vision may be reduced after surgery from widespread laser treatment, but the majority of sight can be saved. Even if vision cannot be improved, laser surgery may help to limit visual loss and minimize damage that would have occurred without treatment. It is important to realize that laser treatment does not usually improve vision, but is aimed at prevention of further visual loss.

This is common with laser treatment and may either take the form of lightening of the skin (Hypo-pigmentation) or darkening (Hyper-pigmentation). During the next three to four days after laser treatment: avoid hot water on the treated skin avoid hot environment e.g. Patients with tanned or those with darker skin types will less favourable with this form of laser treatment. While loss of pigmentation (vitiligo) is unsightly and problematic, the laser goes deeper into the skin than the light treatments. He was very confident and optimistic about what he could achieve by laser treatment to various skin problems I had.

Non-ablative laser treatment uses an intense beam of light to gently stimulate the production of new collagen while bypassing the outer layer of skin. to receive laser treatment for removing port wine stains from their skin. This technique is not effective for treatment of deeper wrinkles and sagging skin treated with laser resurfacing and traditional surgical techniques. Areas of lightened skin, with a visible line of demarcation between treated and untreated areas, were significantly more common with CO2-laser treatment. We have been performing laser hair removal since the 1990s along with laser treatments of skin lesions, pigmentation, veins, tattoos, and scars. This laser is much kinder to dark skin than the Alexandrite laser, and pigmentation problems after treatment are much less common. Tired of the hair war Hi, I don’t have dark skin but have had extensive laser hair treatment on my bikini line and underarms. The effect of cooling the surface of the skin serves to minimize discomfort during treatment while increasing the effectiveness of the laser treatments. The clinician has expressed surprise at the evidently strange way my skin reacts to the laser treatment.

Each eye is complex and unique and has its own shape. Small imperfections in the eye scatters light waves which cause vision impairment. The procedure is done by a qualified and skilled surgeon.

Lasik laser refractive surgery has become an extremely effective treatment in eye correction. The surgery is done as an outpatient procedure and takes about five minutes per eye. The results are dramatic. It is a refractive surgery to correct errors and reshapes the cornea of the eye. It is an effective treatment and enhances the ability to focus. Lasik eye surgery is the most common type of laser vision correction. The procedure is done by a qualified and skilled surgeon. The recovery is minimal and most patients are able to see without vision correction the next day.

According to the U.S. Centers for Disease Control and Prevention (CDC) 45% of adults over 50 have never had a dilated eye exam. 1 out of every 3 adults over 40 has a vision problem. A growing problem is the lack of concern to seek out preventative eye care. With that serious problems with the eyes can go undetected and cause permanent damage. Some threatening eye problems include: cataracts, glaucoma, macular degeneration and presbyopia.

Lasik surgery is refractive surgery to correct vision and eliminate the need for glasses and contact lenses. An initial baseline eye examination is needed with your eye doctor to see if you are a good candidate for Lasik eye surgery. If you wear contact lenses you should stop wearing them for several weeks before Lasik eye surgery since contacts change the shape of the cornea.

Lasik laser eye surgery correct most patient’s common vision problems as with Myopia or nearsightedness; Hyperopia or farsightedness and Astigmatism or distorted vision.

The total procedure takes less than 30 minutes. The laser system includes a large machine with a microscope and an attached computer screen. The laser is used to remove corneal tissue based on measurements taken at your initial evaluation. After the procedure your vision may be hazy or blurry.

This will improve considerably within the first few days. Plan on taking a few days from work until symptoms are gone. A follow up visit is scheduled within the first 24 to 48 hours after surgery to test your vision and examine your eye and regular scheduled interval check ups for at least six months.

Call your eye doctor or Houston Lasik surgeon for more information. Lasik laser surgery is available across America and in Texas in cities as Houston, Dallas, Austin and San Antonio.

Who would have thought that a man without legs can walk again? Yes, with articial implants, a person who has lost both legs can still walk today. That’s the wonder of modern science. The same goes for those who have bad eyesight. Corrective laser eye surgeries can help you see clearly without the need for eye glasses or contact lenses anymore. Although this does not mean that the blind can see, it is still a miracle of sorts.

When we talk laser eye surgery, we usually think LASIK (Laser-assisted In Situ Keratomileusis) but there are also other refractive eye surgery such as : -

1) Photorefractive Keratectomy (PRK) - laser is used to remove tissue found in the surface of the cornea, which is the cause of vision problems.

2) Conductive Keratplasty (CK) - a small probe the size of one strand of hair is used to change the shape of the cornea by shrinking the surrounding tissues.

3) LASEK(Laser Epithelial Keratomileusis), which is a hybrid of photorefractive keratectomy (PRK) and LASIK.

Whatever it is, laser eye surgery will help people who have astigmatism, near or farsightedness, see better.

Due to surging demand, the price for these procedures has gone up in recent years. A reason for the huge demand is the benefits of having good eyesight without the use of cumbersome glasses. A survey of more than 3 million Americans who have had laser surgery claim to live a better life after the operation.

These benefits of corrective laser eye surgeries are :-

i) ability to see well without the use of eyeglasses or contact lenses

ii) makes one look better, thus improving self confidence and esteem

iii) can perform better in certain sporting and other physical events

iv) ability to see clearly when waking up from a nap or after good night’s sleep

v) can treat eye dieseases like glaucoma, presbyopia, macular degeneration and diabetic retinopathy.

vi) no maintenance needed

If you have to wear glasses daily, you will no doubt want to get rid of it. Imagine being able to see thing clearer and not get blurred vision without something hanging on your nose and ears. Even being able to go for a relaxing swim and not bump into something or someone accidentally. Laser eye surgery can make this a reality for you.

Before going for a laser eye surgery, you will be examined by a doctor who will find out the extent of work that needs to be done on your eye. This usually take less than 5 minutes, that’s it. And the good thing is that almost anyone can quality for such procedures.

During the operation, you will not experience any pain since anesthesia will be used. However, the doctor will probably prepare you for any case of itchiness post operation. Some people have the urge to scratch when it itches. This should be avoided so that there will not be any disruption in the healing process that will happen after a few days.

If you are suffering from bad eyesight, it may be time to seriously consider laser eye surgery to remove the need for glasses or contact lenses. Depending on your problems, your doctor may perform LASIK, LESEK, PRK or CK on you. But it is a relatively minor operation and you should be able to return to work after the procedure.

Is the world a complete blur for you without your glasses or contact lenses? And when you do get your glasses on, do you resent the lack of freedom in all your movements? Perhaps it’s time you went in for corrective eye surgery.

Most corrective eye surgery is technically known as refractive eye surgery, an elective procedure intended to correct common eye disorders, or refractive errors, such as myopia (near-sightedness), hyperopia (far-sightedness) and astigmatism (distorted vision).

Where does laser eye surgery come in?

Laser refractive surgery is rapidly becoming the most technologically advanced and popular method available today to correct refractive errors, primarily because it provides near-total precision and predictability. However, there are still a relatively small number of ophthalmologists in the US who are trained in laser refractive surgery and in the calibration and operation of the laser.

The excimer laser, which is used in this type of surgery, received FDA approval in 1995 for correcting mild to moderate nearsightedness. At present, the excimer laser is approved for use in procedures called photorefractive keratectomy (PRK) and laser in situ Keratomileusis (LASIK).

Photorefractive Keratectomy

Performed with local anesthetic eye drops, PRK is a refractive surgery that reshapes the cornea by removing tiny amounts of tissue from the outer surface with a computer-controlled ultraviolet beam of light. The beam is so precise that it can notch a strand of human hair without breaking it. The procedure is the commonest form of laser eye surgery, takes only a few minutes, and you can get back to normal life in a couple of days.

Is Laser Surgery for You?

Millions of patients have experienced total freedom from any kind of eyewear after laser surgery, but there are cons too, as with every surgical procedure. It is best to find out whether you are eligible for laser eye surgery. Here’s a checklist so you don’t end up with worse eyesight than you had before you went in:

- People who are slow healers or have ongoing medical conditions like glaucoma or diabetes are not good candidates for laser surgery

- Those with uncontrolled vascular disease, autoimmune disease, or people with certain eye diseases involving the cornea or retina are also poor candidates, so make sure you have a long chat with your doctor before you opt for surgery

- Pregnant women should avoid refractive surgery of any kind because the refraction of the eye may change during pregnancy

Facts you should know

- You needn’t worry if your pain threshold is low, since there is hardly any discomfort during surgery. Once the anesthetic wears off, the degree of pain varies from individual to individual, but any irritation is minor and usually vanishes within hours

- Worried about when you can return to work? Usually in one to three days post-surgery, but a better idea is to wait until you feel up to it

- Convalescence is minimal, and usually you can be driven home about 30 minutes after surgery. Typically, your eyesight improves within 3 to 5 days

- According to numerous surveys in the U.S. and worldwide, the effects of surgery appear permanent. As people age, however, their vision deteriorates naturally, so re-treatment may be necessary

- Laser surgery does not really restrict your activities, except you should not rub your eyes after surgery. Other than that, you can do whatever work you feel up to provided you follow doctor’s orders

The risk factor

In one word, minimal, but there have been a handful of cases where complications resulting from laser eye surgery have resulted in corneal transplants. So here goes:

- There is about a 0.1 percent chance of the cornea becoming infected after PRK, which usually means added discomfort and a delay in healing, but no long-term effects within a period of four years

- It is as yet not possible to definitely predict how your eye will respond to laser surgery. As a result, you may still need lenses after surgery for good vision. In some cases, a second procedure can improve the initial result

- Some patients find that their best vision with corrective lenses is worse than it was before the surgery. This is a result of either irregular tissue removal or development of corneal haze

- However, corneal haze is part of the normal healing process after PRK. In most cases, it has little or no effect on the final vision. However, some cases of excessive haze interfere with vision. As with under-correction, this can often be corrected by additional laser treatment.

- In some patients the effect of surgery gradually fades over several months. In such cases, a re-treatment is once again usually sufficient

- Some patients experience the halo effect, an optical effect noticed in dim light. As the pupil enlarges, a second faded image is produced by the untreated peripheral cornea. This can interfere with night driving. However, recorded cases are extremely rare.

As of now, a number of other lasers for eye surgery are being tested to determine their safety and efficacy. Such tests may allow for clinical studies involving the excimer laser and the correction of farsightedness, provided the FDA grants approval, which is something a potential patient should always check.
