LASIK Surgery – Top 5 Advantages of LASIK eye surgery
In considering any type of surgery is important to consider the risks and rewards, advantages and disadvantages and advantages and disadvantages. This is true of LASIK eye surgery, too. Just looking at the overall picture is the best decision possible.
So what are some of the benefits of LASIK eye surgery?
First Success Story
LASIK has a history of good success rates. With the "success" are operations that lead to nationalcorrect version. About 80% of LASIK patients achieve the level of visibility they want. This is a big advantage of LASIK.
According Less pain
In most cases, laser eye surgery LASIK is less painful than other types of eye surgery (such as photorefractive keratectomy or PRK). In fact, there is usually little pain associated with any surgery LASIK.
Of course, this is a big advantage of LASIKSurgery, particularly when the surgery in combination with the success rate of LASIK. You can always reduce the amount of pain associated with surgery and the benefits, you could find something worth watching.
Third report of relatively
With LASIK eye surgery, vision correction is usually immediately after surgery or the next day. Vision is obviously a big part of our lives, the results quickly from an eye operation may begreat advantage.
Fourth Quick Recovery
LASIK usually produces quick results and recovery time is fast (in operations, compared to other types of eye). In most cases, LASIK eye surgery does not require sutures or bandages, so recovery time is reduced.
No fifth glasses
Probably the biggest advantage of LASIK eye surgery that corrects vision, so that no patient is most needed glasses or contact lenses. Thisis a lifetime of benefits for claims that people choose a quantity, rather than in the first LASIK.
Naturally this is only one side of history. While there are certainly some strong advantages with LASIK eye surgery, there are some disadvantages. We covered this in another article below.

Cost of Laser Eye Surgery
Corrective laser eye surgery costs vary widely depending upon the procedure. There’s also a wide variation in the cost of equipment used for testing and surgery. Technologies such as eye tracking tear film analysis and measurement of corneal thickness and the laser itself are available at different prices. The Purchasing or leasing of other equipment is also reflected in the procedure fee. There is a royalty fee of $100 to $250 per eye to the excimer laser manufacturer, depending upon the type of equipment used. Procedure fees also include expenses such as operation equipments, surgical staff fees and postoperative and preoperative care.
LASIK prices differ widely from one provider to another and depend on many factors. The only universal standard is that LASIK and other refractive surgery prices are quoted per eye.
Traditional LASIK surgery costs range from $1,400 to $2,000 per eye. LASIK with IntraLase, a procedure in which the epithelium flap is made with a laser rather than a microkeratome, costs more than traditional LASIK. The increase ranges from $250 to $500 per eye, averaging $344. Thus, the cost of LASIK with Intra Lase ranges is $1,600 to 2,500. The price is higher because of the high costs of the system used in surgery. Using Wavefront technology combined with a traditional LASIK procedure increases the price by at least $100.
To help lower the price or make surgery more affordable, there are a number of options available without compromising technology or surgical experience. These include medical insurance, financing options, payment plans, flexible spending plans and tax deductibles.
LASEK, an advanced form of PRK, costs the same as a LASIK procedure. The same increase in price range is present when including Wavefront technology or Intra Lase.
PRK or Photo Refractive Keratectomy is comparatively cheaper and may be performed for a cost of about $1,000 to $1,800.

Causes of Macular Degeneration and How to Deal With It
Age-related macular degeneration, typically abbreviated to AMD, is caused by damage to the macula’s delicate cells – a process that gradually prevents it from working as the cells become worn out. This can cause vision loss if left unchecked, and age-related macular degeneration is currently the leading cause of registered blindness in the western world.
However, this is different to total blindness, since only central eyesight is affected; almost all AMD sufferers retain their peripheral vision.
Despite being one of the eye’s most important components, few people know about the crucial role played by the macula. This small area in the middle of the retina governs the central part of our field of vision, processing sharp details for tasks like reading and writing.
There are two main types of macular degeneration – wet and dry. Also known as advanced AMD, the former involves leaking blood vessels under the macula, and it develops from the more common and insidious dry type, which is caused by a build97up of cellular debris. One eye often deteriorates before the other, making the condition harder to recognize, and many people’s first experience of AMO is a gradually expanding blurred or dark spot in their central vision. Other early symptoms include straight lines appearing distorted, or a blurring of objects, along with light sensitivity and “Seeing” colors that aren’t actually there.
The exact causes of age-related macular degeneration are not fully understood, although the elderly and people with a family history of the condition are at greater risk. Recent research has indicated a link between smoking and AMD; risk rates double and onset takes place considerably earlier, much like the established links between smoking and lung cancer.
Obesity and high cholesterol or blood pressure can also heighten the risks, whereas a diet including green leafy vegetables and fruits rich in zinc or vitamins C and E can help the eyes to fight off macular degeneration.
Since excessive exposure to sunlight over many years may contribute to the disease’s onset, this is another reason to invest in effective sun protection eyewear.
We can test for AMD in several ways, often by dilating the pupils and then using retinal photography to map any changes taking place in the macula. If there are any signs of damage at this stage, your Optometrist may refer you to an eye specialist.
Various treatments are currently available to slow down any deterioration or even partially reverse the onset of some types of AMD. Because age-related macular degeneration is painless and can take years to fully manifest, you may not recognize its symptoms – and as with so many conditions, regular eye examinations are essential to assist with early diagnosis and any course of treatment.

LASIK Can Fix A Number of Refractive Errors
Many types of refractive errors are correctable by Lasik. The end result of the Lasik procedure can be influenced by varying degrees of severity. There are still benefits of having surgery for those with very bad eyes, but they still may need glasses.
Refractive errors are eye conditions which keep light from focusing correctly, causing blurred vision. Glasses or some other sort of corrective device will be needed by that individual, to see focused objects.
In a healthy eye, light will pass through the cornea and lens, and it is able to focus into the correct location on the retina. Refractive errors occur when an eye is misshapen.
Myopia is better known as nearsightedness. This is the most common refractive error correctable by Lasik. A person who has myopia will experience light passing through the cornea and lens, but it then focuses in front of the retina. A cornea that is too long or too curved will easily cause this. A symptom of this condition is blurry vision at a distance.
Farsightedness is also called hyperopia. Lasik surgery can also correct a refractive error. Farsightedness is essentially just the opposite of nearsightedness. Light passes through both cornea and lens and becomes focused behind the retina. In this case, the cornea is too short and flatter than normal. Near vision will be blurry if light is focused behind the retina.
Lasik can also correct astigmatism, which is another type of refractive error. An eye not consistently curved causes this condition. Light passes through the cornea and the lens, and it focuses at various points behind and in front of the retina of patients with astigmatism. Patients who suffer from astigmatism have blurry vision at both close and far distances.
Presbyopia, more commonly known as aging of the eye, is another type of refractive error that can be corrected utilizing Lasik. It typically presents in persons over forty. As people age, they lose the ability to focus the lens of the eye, and that loss causes presbyopia. The need for reading glasses, or bifocals, often comes from this condition. Presbyopia can also be corrected through laser eye surgery.
Each of these is one of the refractive errors Lasik can fix. Every refractive error needs a slightly different method for correction, using the laser technology. The cornea is reshaped using the laser to create peaks and valleys within the cornea. This will in turn cause the light that is passing through, to focus in directly on the retina, which will result in clear vision.
With Lasik laser vision correction, most patients experience clear vision, with the potential of that vision being near perfect. People with acute farsightedness are those who are at a higher risk for requiring the additional support of a weak prescription of corrective lenses after surgery. Your possible success rate should be evaluated, and your concerns should be addressed during the screening process. Keep in mind that no procedure is 100% effective for every single patient.

LASIK Facts to Know
LASIK is the acronym for laser assisted in situ Keratomileusis. It is a laser eye surgery that helps to reshape the cornea so that a person can see without the use of corrective lenses.
LASIK is a very popular surgery and many people are considering getting LASIK. If you are one of them then read on for some LASIK facts that you should know before surgery.
- LASIK was invented in 1950 by Jose Barraquer. He developed the microkeratome machine used in LASIK surgery.
- The Excimer laser, the main laser used in LASIK surgery, was invented in 1968 at the Northup Corporation Research and Technology Center at the university of California.
- LASIK has a lower pain and complication rate then other forms of laser eye surgery.
- The laser is not used in every part of the surgery. In most LASIK surgeries the initial flap in the cornea is made with a scalpel.
- The flap cut in the cornea is not secured in any way after surgery. It is simply laid back into place and left to heal naturally.
- Contact lenses can cause the cornea to be reshaped and so patients are recommended to stop wearing them for six or more weeks, depending on how long the patient has worn contacts, before surgery for the best LASIK results.
- Antibiotics are often prescribed prior to surgery to help prevent infection after surgery.
- A patient is awake during LASIK surgery.
- Wearing the dark glasses after surgery is important to protecting the eyes from bright lights.
- Pupil size can cause side effects after the surgery which can cause vision problems.
- Subconjunctival hemorrhage, where blood vessels in the eye rupture and bleed into the whites of the eyes, is a common side effect of LASIK, but is minor and corrects itself within days after the surgery.
- A slipped flap is one of the most common complications of LASIK. A person can minimize their risk by following all doctors orders after surgery.
- Some patients may still need to wear reading glasses after LASIK surgery because this condition is not related to the cornea or shape of the cornea and is, instead, an age related occurrence.
- High heat and humidity can effect the results of LASIK surgery and recovery process.
- LASIK is used for correcting myopia, hyperopia and astigmatism only.
- Satisfaction with LASIK results ranges from 92 to 98%.

Cataracts Do Not Mean Losing Sight
It is hard for a person with good eyesight to imagine living in a world that is cloudy and murky. Worse than any rainy day in fall, this murk and haze is a constant. It hinders every facet of life from driving to reading a recipe. No longer are the colors vibrant and the images clear. People living with cataracts understand this example. The world has slowly lost focus as the white, milky substance overtakes their vision.
All cataracts are made up of proteins in the eye that begin to adhere together. A cataract begins very small. Imagine wearing a pair of glasses and there being a tiny smudge in the corner. When the smudge starts out, it is just a tiny pinpoint. Over time, the smudge begins to grow and take up more area on the surface of the lens. Everything viewed through that lens distorts. That is how a cataract is. There are three types of cataracts: nuclear, sub capsular and a cortical. They differ on what causes them as well as how they manifest themselves. A nuclear cataract is most often associated with natural aging. It forms on the nucleus of the eye, hence nuclear cataract. A cataract that form at the back of the eye and is most often associated with having diabetes or high farsightedness is the sub capsular. Diabetics also have to worry about forming the third form of cataract, the cortical. The cortical cataract extends out from the center of the eye in a similar resemblance to bicycle spokes.
A simple artificial lens marks the difference in being able to see clearly and shrouded in haze. The ophthalmologist removes the old, damaged lens and replaces it. The surgery itself is simple and is an outpatient treatment. Within a few weeks, the patient recovers and their eyesight is vastly improved. It is that easy.
Cataracts do not have to mark the end of independence and vision. They do not have to be just a mark of growing old. With today’s procedures, a person can live a full active life without the worry of losing his or her eyesight. Independence happens for the growing aging population. Seniors no longer have to live in a slowly darkening world devoid of bright colors and lights.

Learn – What is LASIK Wavefront?
LASIK wavefront, others may know as wavefront-guided LASIK, or custom LASIK surgery. With this kind of surgery, three-dimensional measurements are taken on the eye and how they use utilize the light that comes through. Generally, it is believed that this type of measurement allows the cornea to be reshaped properly.
When the best results are obtained, the irregularities are corrected with the way that images are processed. In most cases, the common types of defects within a person’s vision can be corrected with eyeglasses, as well as contacts, and the regular kinds of LASIK surgery. The normal cases of hyeropia, myopia, and astigmatism can be corrected through the traditional ways for correction. On the other hand, when the eye has some kind of irregularity, then the Wave front LASIK is the best way for spotting and treating that irregularity.
It’s believed that the type of correction that it enables with an individuals sight, is more profound than the standard kind of LASIK surgery. The way that this kind of surgery differs is how it takes in account the different eyes and vision ranges that an individual has, therefore making adjustments that are needed accordingly.
This kind of surgery seems to have a high success rate, due to the way that it takes into account the individual differences of people. The kind of eye correction that a person has is not something that a person can get through the use of glasses or contact lenses. In order to have LASIK wavefront, there are certain requirements that an individual must meet.
Often the success of the surgery has to do with the doctor that is performing the surgery. For this reason it is important that a person make sure that a doctor has a good record with their use of the laser system. Usually, it is not hard to find information pertaining to others experiences with the doctor.
Additional factors to consider, is how thick your cornea is, as well as if you have mild to moderate high amounts of myopia, hyperopia, or astigmatism. The best person to evaluate you is someone that has experience within this field. In any case, it is important to ensure that you are in fact a good candidate for Wavefront LASIK surgery.
Many of the individuals who have the LASIK wavefront, will usually have an increase in the amount they can see, as well as their sensitivity to contrast. In most cases, the success an individual experiences depends on their initial vision problems before the surgery. In any case, this kind of surgery does not have many complications that are involved with its usage.
LASIK wavefront works well l with the correction of a person’s ability to see better at nighttime as well as the individuals sensitivity experienced in accordance to contrast. Additionally, it can work well to correct any problems with shadows, glares, and halos. Although this type of treatment is more expensive, it works better, since it does a thorough analysis of the individual’s current difficulties that they experience when they are trying to see something.

Glaucoma and Laser Surgery
Certain factors can cause poor drainage of aqueous fluids in the eye and this results in the build up of pressure which can cause damage to the optic nerves that helps the eye function for vision. This leads to an eye disease called glaucoma and if left untreated, it can cause permanent loss of vision. Through the years many techniques and procedures have been developed to diagnose and treat it and at this time the most promising solution is glaucoma laser surgery.
Glaucoma comes in different forms and determining what type of glaucoma a patient has helps in determining what treatment options there are. Initially, in an attempt to relieve pressure in the eye, doctors give eye drops and medication taken orally are given. If it does not help, then glaucoma laser surgery is the next option.
Argon laser trabeculoplasty is one form of glaucoma laser surgery technique used primary open angle glaucoma. Tiny burns are made into the trabecular network of the eyes to improve the draining and flow of aqueous fluid in the eyes. A specific form of this procedure is selective laser trabeculoplasty or SLT. This uses laser beams to remove only very specific target cells in the trabecular network. As a result, it improves the flow of aqueous fluids and relieves the pressure.
In some cases, it may take two sessions and in some, it may require repeating the procedure after two or three years. This, however is recommended because it avoids the need for medication after the procedure. It is also the glaucoma laser surgery procedure commonly recommended for pigmentary glaucoma which is common among males of African-American descent.
Angle closure glaucoma results if the space or angle between the iris and cornea is too narrow and this results in poor drainage of aqueous fluids. Peripheral iridotomy is the glaucoma laser surgery option for this type.
To relieve the pressure, laser beams are used to make a small hole on the iris. The space or angle widens as the iris moves away from it. This corrects the flow of aqueous fluids.
For more severe cases of glaucoma, the procedure usually recommended is laser cyclophotocoagulation. An example is when new blood vessels are formed in the eye as a result of diabetic retinopathy. The new blood vessels can seriously affect the flow of aqueous fluids in the eye resulting in pressure buildup. This leads to a form of glaucoma called neovascular glaucoma.
For this glaucoma laser surgery procedure, the doctor uses endoscopic cyclophotocoagulation to observe the ciliary body. This is also connected to an endoscopic camera. This will then guide the application of the laser beam to treat the ciliary body so it reduces or stops the production of fluids. By using a laser beam, part of the ciliary body is destroyed so that it no longer produces aqueous fluid. Less aqueous fluid means less pressure on the eye.
These glaucoma laser surgery procedures are usually painless. Some may feel a slight stinging sensation but apart from that, no major pain is felt. After undergoing glaucoma laser surgery, some rest for a few days is required and soon one can go back to the normal daily routine.
Also, in some cases, the patient needs to take some medication to relieve some minor discomforts that may appear after the procedure. Eye inflammation and slight risks in developing cataract may be some of the problems that may arise after each glaucoma laser surgery.
Glaucoma is a serious problem that can lead to permanent damage to the eye. It is important that it is well-understood and that a number of techniques are available to treat it.
Laser surgery is fast becoming a popular option for glaucoma treatment. The techniques are also becoming more and more advanced and refined to ensure that treatment results only in success and there is complete absence of discomfort during and after the treatment. They are also being improved to make the positive results long lasting, making glaucoma laser surgery a very promising form of treatment for glaucoma patients. As with any medical problem, thoroughly discuss all options with your physician.

Side Effects of Laser Eye Surgery – Risks of Lasik Eye Surgery Procedure
Although the use of the excimer laser in laser eye surgery has significantly improved outcomes for the patients, the procedure can also result in laser-related side effects. The two primary laser-related side effects of laser eye surgery are decentration and irregular astigmatism.
Even with the use of various tracking devices, decentration can still occur. It is still possible for the excimer laser not to hit its specific target. Decentration produces a number of symptoms, such as poor vision, glare, halos and ghosting, to name a few. The symptoms are caused by the scattering of light at the edge of the area that was ablated.
Certain conditions have been noted to contribute to the occurrence of decentration. These include the degree of nearsightedness of the patient, the experience of the surgeon, and the specific location of the patient’s visual axis line. In general, the more nearsighted a patient is, the less is the patient’s ability to fixate on a light source, and the more likely it may can occur.
This can be diagnosed with the use of wavefront analysis. Treatment of this includes the use of customized ablations of the cornea or the use of topographic linked systems.
IRREGULAR ASTIGMATISM
Another side effect that is related to the use of the excimer laser is irregular astigmatism. This typically presents in the same way as decentration, characterized by blurring of vision and the occurrence of visual aberrations.
Irregular astigmatism can actually be caused by other complications of laser eye surgery, such as homogeneity of the excimer laser beam, and problems with healing. Certain flap complications that lead to the formation of corneal scars can also result in irregular astigmatism. It can also be caused by excess tissue that was not sufficiently ablated. These tissues, known as central islands, resolve spontaneously without any intervention.
Treatment of it is via the use of a rigid contact lens. For patients who do not want the hassle involved with the use of contact lenses, an alternative treatment to irregular astigmatism is corneal transplantation. However, this method is usually employed as a last resort.
In general, the use of the excimer laser in laser eye surgery has resulted in more benefits than complications. However, it is still important to be aware of the possible side effects that these excimer lasers can bring about, so that you can be prepared for any complications that can occur.
