Wavefront Lasik

Astigmatism Lasik has helped millions of patients with refractive errors like myopia, hyperopia e. The operation is known as a rapid procedure with minimal recovery and immediate results. Vision results differ for different patients. Find out more about what you expect from laser eye surgery.

Lasik Surgery

The procedure is performed by creating a flap in the outer layer of the cornea with a microkeratome blade. The surgeon then uses aexcimer laser reshape the cornea. The flap is replaced and serves as a natural bandage.

Your responsibilities during Lasik Recovery

The best results are obtained from a healthy patient and a qualified surgeon. But success during recovery also depends on you. Following the postoperative instructions are essential for a speedy recovery.

Schedule a follow-up examinations

Apart from the instructions of laser eye surgery, you must also planFollow-up examinations. The first follow-up is about 1-2 days after surgery. The surgeon will monitor the success of the procedure and monitor the healing process as well. This is an opportunity to have any problems you may be correct.

Vision after LASIK results

Results of vision and healing time varies from patient to patient. As a guideline, you should see a visual improvement on the first day. You can expect blurred vision immediately after surgery and halos,Starburst and sensitivity to light. But the majority of Lasik patients report a 90 percent improvement within 24 hours after the operation. Many patients without glasses or contact lenses to see the day after their corrective surgery. Vision is to continue to improve during the first weeks.

Healing

You can see some problems during the first two days after the experience of surgery. The most common symptoms are burning and irritation. For the first three weeks after Lasik, do not rubEyes under any circumstances. Rub your eyes can stop during the early recovery of the corneal flap.

As part of the recovery process, your doctor may prescribe artificial tears, steroid drops and antibiotic eye drops. Eye drops to promote healing and prevent infection. If you experience complications with dry eyes may be necessary to administer artificial tears for the first three weeks.

Most vision side effects subside within a few days after the operation. However, full recovery cantake some time. Your eyes can adjust up to six months to full correction. Taking care of your eyes, as indicated by the surgeon performing the operation.

You can continue to improve vision after Lasik surgery. You may also experience periods of fluctuating vision. This is a common occurrence. Visual acuity is immediate, but the visual clarity may take some time. During the healing phase, you will notice your eyes slowly contrast sensitivity, a termdescribe the contrast between the priority and the object and background.

The occurrence of red eye symptoms (e.g. as in subconjunctival hemorrhage) often indicates high blood pressure. Most common causes for poor blood circulation are free radical damage to the circulatory system, lack of healthy nutrition (deficiency of vitamins, minerals, aminos acids and essential fatty acids) and acid toxins within the body. As a result the veins, arteries and capillaries will not be able to cope and may cause poor blood circulation. Medicines and supplements that may increase the risk of a subconjunctival hemorrhage are : Blood-thinning medications, such as warfarin and aspirin, Ginseng, Ginkgo, Garlic,Ginger,St. John’s wort, Cayenne.

You may improve your blood circulation in many ways :

do not smoke, the nicotine causes your blood vessels to constrict and your heart to beat faster, and this raises your blood pressure. Most people breathe improperly by using only the upper portion of lungs; Hydrotherapy (hot and cold shower) may help to improve blood circulation. Avoid stressful situations. Regular exercise will have positive results on your blood flow. Choose a diet that includes lots of fruits and vegetables and is low in fat. Reduce proteins and saturated fats (found in red meat, cheese and cream). Effective circulation boosting foods are pumpkin seeds , oranges, nuts, watermelon, garlic.

Improving sleep may also help to improve blood circulation, here are some tips to improve your sleep : Avoid large meals before bedtime, or going to bed feeling hungry. Avoid sources of caffeine such as cigarettes, alcohol, coffee, chocolate, fizzy drinks non-herbal teas (Caffeine takes 8 hours to metabolize). Sleep is often disturbed in smokers and those who withdraw from heavy nicotine use. Although alcohol helps to fall asleep but the sleep will be very poor quality & fragmented. Regular exercise improves your sleep (although do not exercise close to bed time). Go to bed as early as possible and create a pattern of going to bed and waking up at the same time.

LASIK and LASEK are similar forms of laser eye surgery used to correct nearsightedness, farsightedness, astigmatism, and (with special conditions) presbyopia. LASIK is an acronym for “Laser-Assisted In Situ Keratomileusis,” while LASEK stands for “Laser Assisted Sub-Epithelial Keratomileusis.” The reference to “sub-epithelial” in the second acronym provides a clue to the differences between these two surgeries.

Epithelium

In LASEK, the epithelium, or thinnest outer layer of the cornea, is cut not with the microkeratome cutting blade used in LASIK, but with a finer tool called a trephine. Both surgeries create a covering for the cornea, which can be put back in place at the end of the procedure. Because it uses a thinner cutting instrument, the LASEK procedure can create this covering from just the epithelium, whereas LASIK involves cutting into deeper layers of the cornea.

When the epithelial layer has been moved out of the way, a laser alters the shape of the cornea below, and then the epithelium is returned to its natural place. Sometimes the thin tissue is too weak to be laid back in place. In these cases, it’s removed, essentially turning the procedure into a PRK.

Results

Using the epithelium layer as a natural protective bandage may improve healing and reduce the incidence of postoperative haze, when compared to PRK. Although all the tissue is present immediately following surgery, it needs time to adhere to your eye. A smooth, central epithelium is crucial for clear vision. It normally takes three to ten days for the layer to heal and resurface the cornea.

Both LASEK and LASIK procedures have their pluses and minuses. After the epithelial “E” surgery, recovery takes a few days longer and may involve greater post-operative pain than the “I” surgery, which, despite involving a deeper cut, is generally painless. On the other hand, LASEK is less likely to result in dry eye issues than LASIK and results in fewer post-operative haze problems, perhaps because “E” preserves more corneal tissue.

In a Haze

Haze is a scar-like material in the cornea, caused by the cornea’s wound response. A cornea’s “healing haze,” usually lasts for three to six months. The stronger the prescription being treated, the greater the problem, and the more unpredictable the results. Haze involves the body laying down of tissue and thus results in a partial reversal of the treatment. It’s not usually bad enough to impair vision, but can produce glare when driving at night. Even with LASEK, there may be a higher incidence of cloudiness of the cornea for patients having very high degrees of nearsightedness (myopia).

Good Candidates

“E” surgery is a great option for patients previously turned down for “I” surgery because of thin or unusually shaped corneas or large pupils. It’s also better for people with dry eye syndrome because it involves cutting such a thin layer that the corneal nerves controlling our tearing reflex are left undamaged. Laser “E” surgery is relatively new and is only performed by select laser vision correction surgeons, so candidates must have access to a surgeon experienced with the procedure and equipment.

Over the past couple of years, my mother has complained about how her vision was giving her problems. However, she never did anything about it until recently. When I spoke to her a few weeks ago, I was telling her about how I had to drive my grandmother back from a party that my uncle had thrown at his house. It was a dinner party, so by the time that we left, it was dark outside. My grandmother had made no excuses when she told me quite frankly that driving at night made her nervous. As I was relaying this to my mother, she told me that her vision had deteriorated to the point where she actually had to call my younger brother to come and pick her up from work because she was too nervous to drive home.

As you get older, many people experience problems with their vision. However, this is not always the case. When I was in college and was studying for my thesis, I began to have trouble seeing the blackboard. It eventually got to the point where I really could not decipher what the professor had written on the board, so as a result, I would continually have to ask one of my classmates for their notes so that I could copy down what had been written. I knew that I was going to have to do something eventually. I also began to notice that when I was driving (especially at night), I was having a great deal of difficulty making out the street names on the signs. Not being able to see the blackboard was one thing, but it was quite another to not be able to see clearly while driving, so I made an appointment to have my eyes checked. Sure enough, I needed glasses.

With my mother’s case, my father had just bought her a new car, and her job required her to close up the store sometimes late at night. In addition to that, she also tutors children on occasion in the evenings, so being able to see clearly was especially important for her in her daily life. Just two days before her birthday, she had the day off from work and decided to go with my brother to the optometrist. The result? She had the beginnings of a cataract in one eye, and her vision required her to get glasses. The day before her birthday, she picked up her new glasses. While she was greatly disappointed at having to wear glasses, she was increasingly grateful to be able to see clearly again.

Too often, automotive accidents occur because of driver error. Either the driver is unable to see clearly or is distracted by something else that they are doing in the vehicle such as eating, talking on the cell phone and/or texting. Knowing that you need to get glasses or at least go in for a checkup is not only the responsible thing to do, but it helps keep you and other drivers/pedestrians out there safe. The last thing that you want to have happen is you accidentally hit someone simply because you couldn’t see or weren’t paying attention.

Is it possible to get what you want, help the environment, and save money all at the same time? That’s a lot to ask for, but yes it is all possible if you buy select recycled products such as eyewear.

Environmental issues are important today and for future generations.. We all hear buzz words like “global warming”, “ozone layer”, “ice caps melting”, “green house gases”, etc…. The scientific evidence supporting these events has grown to the point that it’s probably accepted by most people as being a part of life and a part of the problems we are facing all over this planet. But we don’t have to just sit there and accept it, and watch it worsen with each passing day; let’s do something about it. Everyone has the power to help the environment and every little bit adds up. How about starting with something as simple as eyewear?

For billions of people on this planet, eyewear is a necessity, and for some it is a luxury. For more than half of the current US population of 300 million, vision correction is a necessity (www.allaboutvision.com). According to the American Sunglass Market 2005 report, 86% of the US population wears sunglasses, some to protect themselves against damaging UV rays, others just to look good. Much of the eyewear being worn today is ultimately discarded. Recycled eyewear is an option that is not radical, but could make a tangible and positive impact on our environment with the added benefit of saving some dollars.

Let’s start with the definition of recycled eyewear. Basically, it’s existing eyewear that is reconditioned (i.e., sterilized, cleaned, repaired, and qualified for resale) and sold rather than sitting in a land fill somewhere for thousands of years. It’s the most energy efficient, cost effective, and environmentally friendly alternative to new eyewear. It’s not eyewear that is reconstructed from existing materials or manufactured from plastics and metals that have been recycled. It is simply the process of taking existing eyewear, reconditioning it, and reusing it.

Brand new eyewear can be incredibly expensive whether you buy from a brick and mortar store, a web based retailer, or whatever other channel you desire. All of these businesses have to sell the product within a reasonable price range of each other, if they could sell it for significantly cheaper prices, market forces would pull in competitors and the overall price of new eyewear would come down dramatically, but this has not happened. The average retail price of a new frame was $126.21 in 2002, according to 20/20 Magazine VisionWatch. Shop around and you will find many frames that are two, three, or more times this price. What are you really paying for? Well, brands and styles for starters, but beyond that it’s all pretty much the same plastic and metal. If you are a high earner with good health care benefits, you may not care. However, for the low-to- middle income families out there, this could be a big dip into the bank account. On the other hand, recycled eyewear is available at prices that are up to 90% below the best prices you can find for brand new product. If you don’t believe me, visit Equation, LLC at http://www.equationLLC.com and you’ll see for yourself.

Our emotional well being is a big driving force when it comes to shopping. We all want to have the ability to accessorize and purchase different styles and colors of prescription eyeglasses and sunglasses, but who can realistically afford this? The answer is very few. Recycled eyewear opens this luxury to the other 99% of the population that has the desire but not the disposable income. Be happy; get the eyewear you want, and help the planet!

Now let’s focus on the environment and the impact you can make by purchasing recycled sunglasses, recycled reading glasses, and recycled eyeglass frames. The manufacturing of eyewear involves several steps, all of which require energy in the form of electricity. The biggest energy consuming step is the process of machining components, machining molds, and injection molding components. The parts then need to be assembled and the complete eyewear needs to be cleaned and tested. Now, if recycled plastics and metals are used, they still need to be melted down and then inserted into the process I just mentioned, so that scenario may reduce land fill waste, but it increases other forms of pollution. All of these steps require machines and lights to be running on electricity and as we all know, when electricity is made, pollution is released into the environment which then leads to the many environmental problems we hear about everyday. Fully recycled eyewear consumes little to no additional energy or electricity and therefore does not contribute to pollution and the environmental problems we are facing.

Recycled eyewear is the only alternative for those who want to save money, satisfy their emotional desire to accessorize, and help the environment. Virtually no energy is required to recycle eyewear and the savings can be hundreds of dollars per person. Companies such as Equation, LLC are leading the charge and you could be the beneficiary.

Getting an anti-reflective coating applied to your lenses is a smart choice. The plastic lenses generally used in glasses or sunglasses usually transmit only 90% of the available light to the eyes. The remaining 10% of light is often obstructed by reflections on the lenses.

Anti-reflective coating is an optical coating that is applied to the surface of the lens of glasses or sunglasses to improve efficiency where light would normally be lost due to reflections. It was originally created to reduce reflections on camera lenses and is now also used to improve the vision of millions of people who wear glasses or sunglasses.

A few of the many reasons people have decided to have an anti-reflective coating applied to their glasses or sunglasses are:

While it improves transparency, it also reduces the reflections in the glasses or sunglasses improving their appearance.
It makes it easier for a glasses or sunglasses wearer to have direct eye contact with another person without his or her view being obstructed by reflections.
By reducing glare, it makes vision more crisp and clear than would be possible if the lenses were not coated.
It improves driving safety by allowing drivers to focus on the road without distractions from headlights and streetlights.
It reduces eyestrain for people who use computers often by decreasing glare from the computer screen.
It reduces eye fatigue for people who work in offices by lessening overhead glare that can be caused by unnatural lighting often found in offices.
It enhances the quality of a lens and also lengthens its lifetime by providing durability and resistance to water, dirt, heat, and scratches.

There are different types of anti-reflective coating. The best quality anti-reflective coatings are water-resistant because of a hydrophobic layer that prevents water spots from developing on the lens. This same hydrophobic layer makes it easier to clean lenses without damaging them. Another layer anti-reflective coatings may include is an oleophobic layer. The oleophobic layer makes lenses resistant to the oil that is naturally excreted through your skin or any moisturizers you may wear. This layer also makes it easier to clean smudges off your lenses.

Getting an anti-reflective coating applied to your lenses is a great choice because they reduce reflections on your glasses or sunglasses and improve the durability of your lenses. Additional advantages are: less eyestrain, less eye fatigue, better vision, better eye contact, and safer driving.

Many people are familiar with the term “laser eye surgery” and know it to be a type of corrective surgery to help improve various vision impairments. Lasik has become a very popular solution for many people, since it became widely available about a decade ago, in the mid 1990s.

Unlike older forms of eye surgery, Lasik does not necessitate cutting the eye with a surgical scalpel. Instead, lasers are used to do the job. Recently, custom wavefront Lasik surgery was introduced as an advancement to the basic Lasik method.

The phrase “custom wavefront” is actually not as new as might be thought. The term “waterfront” has actually been around for almost a century and was commonly used in astronomy, as a concept of using mirrors and various lenses to manipulate rays of light.

However, the term was applied to the Lasik form of laser eye surgery about a decade ago, in the late 1990s. These same principles began to be applied to the corrective procedures to enhance the outcome of Lasik surgeries.

What really makes the custom wavefront Lasik method different from the standard lasik eye surgery is that it provides the Lasik eye doctor with a considerable amount of additional, detailed information to help him better pinpoint the exact problems in the eye that need to be corrected. This is done by a mapping process that uses the way the light passes through the eye to reveal a three-dimensional image of the interior of the eye.

The Lasik custom wavefront procedure essentially “unravels” the way that the light passes through the eye of the patient. Because of this, during the examination of the eye, the doctor is able to see all the way to the retina at the back of the eye, giving him a view of the functioning, or malfunctioning patient’s optical system. It is this detail that allows the Lasik eye doctor to identify the minute imperfections and damaged areas of the eye that traditional types of eye examinations often missed completely.

The result of this greatly improved ability to see the inner working of a person’s optical system is that the laser eye surgeon can then use this information to perform a much more effective custom wavefront eye surgery. Patients enjoy a greater degree of improvement in their eyesight, when compared to the results of the older Lasik procedure.

The custom wavefront Lasik surgery is still considered relatively new, and it is a more expensive procedure than the standard Lasik vision corrective surgery. However, for many people who are suffering from poor vision problems, the cost of Lasik surgery of any kind is quite small compared to the benefits of improved eye sight that they enjoy with very little risk or complications.
