All About Lasik

If you have what has been determined as humanity’s “normal” eyesight, you have 20/20 vision. In countries which use metric measurements, it is called 6/6 vision, referring to meters instead of feet. 20/20 vision is not “perfect” vision, but it is clear at all distances, needing no glasses or contact lenses. Vision can be better than 20/20, so let’s look at that further down this article.

The Snellen Eye Chart

Most of us are familiar with that eye chart which has a single large letter at the top (usually an

“E”) and rows of progressively smaller letters below it. There are some variations on the most common version of this chart. In all versions, one line is designated as the “normal vision” line and the others test your vision relative to that “normal” line.

When your eye doctor tests your vision for a glasses or contact lens prescription, the eye chart is seen through an ophthalmic device called a phoropter. You rest your chin and forehead against smooth surfaces and look with one eye at a time at the lighted chart inside the aperture.

There are also printed charts that can hang on the wall, and these can test your vision too, but the phoropter is more precise. Instead of you having to physically stand a certain distance away from it, distance is simulated by the phoropter’s optics.

From Twenty Feet Away

Normality is defined as a clear perception of the designated “normal” line of letters at 20 feet from the eye chart. That is the first “20”. The second number, which may or may not be “20” is a comparison between the tested eye and a “normal” eye. The higher the second number is, the more vision impairment your eyes have.

· If a normal eye can see from 40 feet away what you must stand only 20 feet away to see, your vision is described as “20/40”.

· If a normal eye can see from 100 feet away what you can only see if you stand 20 feet away, your vision is “20/100”.

· If your vision is described as “20/200”, you are legally blind.

To describe this another way, imagine you moving back and forth from the eye chart, trying to see the “normal” line clearly. If you can see it clearly from 20 feet away, your eyesight is 20/20. If you must edge closer to the chart to see it, your vision is impaired and you are nearsighted.

But ophthalmologists don’t usually measure those closer distances in defining your visual acuity. They talk in terms of further distances and postulate that the tested eye is always at 20 feet from the chart. They then compare that amount of acuity with what a normal eye has at varying distances. When the normal eye can see from 80 feet what you see at 20 feet, your vision is 20/80.

Vision Better Than “Normal”

· If your vision is 20/16 you can see from 20 feet away what a “normal” eye can only see from 16 feet. That is better visual acuity than what we consider to be normal.

After a Custom LASIK surgery many people can see with 20/16 clarity. Their vision has been made better than humanity’s normal vision. Custom LASIK is based on a more sophisticated and accurate diagnosis than the original Traditional LASIK was. A Custom LASIK procedure does more than just correct nearsightedness, farsightedness and/or astigmatism (that is, the three Lower Order Aberrations).

It also corrects the tiny irregularities called Higher Order Aberrations. A phoropter is not used to diagnose your eyes for Custom LASIK. Instead, a newer technology is used called Wavefront technology. It shines a light into each eye and measures the slight changes in it as it reflects back from your eye into the Wavefront system. From the resulting colored 3-D maps of each eye’s contours, your LASIK surgeon can plan a more precise treatment.

When the Custom LASIK laser smoothes out these microscopic irregularities in the eye’s cornea (clear front part), your vision improves beyond what glasses or contact lenses can achieve. This is how a person can achieve 20/16 vision – better than normal. The Higher Order Aberrations cause visual distortions which show up in dim light, such as halos around light sources, decreased contrast between light and dark, and faint duplicate images. When these are corrected, your vision is clearer in all lighting conditions.

Not everyone is a good candidate for LASIK eye surgery. But what if you still want to improve your vision while reducing or eliminating the need for glasses or contacts?

A popular alternative to LASIK surgery is ICL, or Implantable Contact Lens, also sometimes referred to as a permanent contact lens. An ICL is a soft lens that is attached to the eye for correcting nearsightedness. An Implanted Contact Lens is intended to be permanent, but it can be replaced if changes are needed in the future. Unlike LASIK eye surgery, the ICL procedure is completely reversible.

There are certain advantages to ICL over LASIK. For example, with LASIK, permanent changes are made to your eye and those changes are something you’ll have to live with. If the LASIK procedure worked out you’re OK, but if it didn’t, you’re stuck with it. In stark contrast, Implantable Contact Lenses can be changed out at any time if corrections are needed.

If you’ve previously worn contact lenses, you already know the hassles of normal contacts – cleaning, soaking, removing and replacing, etc. But with implantable contact lenses, all those frustrations immediately disappear. The implants are permanent and should never require any attention unless your vision changes as you age. Implantable contact lenses provide the same vision improvements as normal temporary contact lenses, but they require none of the attention and maintenance of normal contact lenses.

The ICL procedure is usually done on an outpatient basis and you’ll experience little or no pain. A mild sedative is administered to provide a calming effect and a 1/8 inch incision is made for insertion of the lens. Once inserted, the lens is properly positioned. In almost all cases, sutures are not required to close the incision point. If you’re having the procedure performed on both eyes, they’ll both be completed in a single session. The entire procedure is usually completed within about 30 minutes.

Upon completion of the ICL procedure, you’ll be sent to a ‘post-op’ area for recovery. Once staff members determine that you’re stable, you’ll be sent home to relax for the remainder of the day. You’ll need to return the next day for a follow-up exam, just to make sure that everything is OK.

There may be some mild haziness upon completion of the implantation, but this usually clears itself within a short period of time. Most patients see quick improvements in vision, with about 90% of normal vision restored within the first 24 hours. Normally, your vision on the second day will be good enough to allow you to drive yourself to the examination.

The main issue of concern with implantable contact lenses is the risk of infection. Infection is a serious condition that can result in the loss of vision, so your doctor will take the necessary precautions while performing the procedure.

Implantable contact lenses are a reasonable alternative to LASIK surgery for patients who have trouble seeing at a distance. However, ICL does not help you if you need reading glasses.

People that were forced to wear contacts or glasses all their life can now leave these aids behind by using a new and innovative LASIK procedure called the LASIK eye surgery.

This new type of refractive eye surgery can be risky but in most cases after detailed testing and consultation the final result is a good one. If you worry about the duration of the surgery, you should know that everything lasts only a few minutes but in order to obtain good results you should be very careful about the pre and post operative appointments.

It is very important to choose a good eye surgeon and after he evaluates he’ll establish the details of the procedure. He’ll let you know if you’re a good candidate or not, he’ll explain the procedure, the complications, the risks and the final result and together you’ll set the post-op appointment.

A few weeks before the LASIK eye procedure it’s recommended that you use only glasses and no contact lens because the shape of the cornea plays the most important role during evaluation.

When the procedure starts you’ll be sitting in a chair while the doctor will put numbing drops in your eyes. After he cleans up the area around the eyes, he’ll use a machine that will keep your eye lids open.

You might feel pretty weird because our eye lids are programmed to shut but if you stay relaxed you won’t feel a thing. The lasik eye surgeon use various types of machines and that’s why the level of discomfort can vary a lot from one patient to another.

Next, you’ll have to look straight into a laser placed over your eye while the surgeon will complete the procedure.

Everything happens very fast and the discomfort will only last a few seconds. All the above mentioned details sound scary and when you think that everything happens in the eye you might reconsider but you shouldn’t. LASIK eye procedure is very safe and most candidates leave the hospital with excellent results.

While the vast majority of our LASIK patients are satisfied with the results of their initial surgery, there are instances when a patient requests or may require an enhancement.

We will perform a follow-up LASIK enhancement if you are unsatisfied with the initial result and it is reasonable to do so, or as a corrective measure due to complications during the surgery or healing process.

Generally speaking, we do not recommend follow-up enhancements unless you are left unable to perform necessary activities as a result of your surgery. With an enhancement come all the risks of the initial surgery, so the choice to undergo an enhancement should be taken just as seriously.

We typically allow 3 to 4 months to pass before considering a follow-up enhancement. This time allows the eye to heal from the initial surgery and the vision to stabilize. It is important to be patient while your eye heals, as it is very likely that the quality of your vision will fluctuate during this time. If you are unable to perform necessary tasks at any time during these first few months due to vision problems, we will gladly provide glasses for you to wear temporarily until your vision stabilizes and an enhancement becomes feasible.

It is important to have realistic expectations before choosing to undergo LASIK surgery. Additionally, there are many factors which will affect your satisfaction with the results of your LASIK procedure. Your eye doctor will discuss these with you in depth during your initial consultation and examination.

If you live in the New Jersey area and are considering LASIK surgery, or have any further questions about the LASIK procedure, please contact us today to arrange a consultation.

After his lasik eye surgery, he claims to experience an improvement in viewing the holes on the green. A leading refractive industry newsletter reported that the average cost for LASIK eye surgery in the second quarter of 2005 was 1,965 USD.

There are thousands all across the USA, who are taking to Laser Eye Surgery, the most exciting advancement in ophthalmology.

Those undergoing Lasik eye surgery in New York often have little problem finding reputable and experienced surgical centers.

Instead he searched for a job for the maintenance of his family and also important treatments of his parents like eye surgery, especially if the procedure to be done is in the face, like a rhinoplasty (nose surgery), blepharoplasty (eye surgery) or rhytidectomy (face lift), you could end up having to stare at your ‘cheap’ doctor’s mistakes in the mirror every day.

If in the third quarter you decide that you want to get laser eye surgery or take a vacation write down where and how much, 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.

The important thing to remember if you consider yourself a candidate; get as much information as you can from Lasik eye surgery reviews and do a little shopping around when searching for surgeons.

People who wear glasses or lens may consult them to verify whether they require a laser eye surgery. But be warned, having eye surgery today based simply on one center advertising the procedure at hundreds of dollars less than another is in no way, any reason to rush in and jump under a laser. Laser eye surgery also works for age-related vision problems.

In LASIK eye surgery, the skills of the physician or surgeon are more important than in the PRK procedure, where the computer does most of the work.

While lasik eye surgery is reasonably safe, any complications which do arise will need to be treated and therefore can ‘blow out’ the original quote. Take the recent LASIK eye surgery offer I’ve received in the mail last month.

The FDA had not yet approved laser eye surgery and so it was only available in Canada. It’s time to ditch this hassle and look into lasik eye surgery. Won’t I go blind from such an eye surgery?

Eye surgery technology on the improve there may come a time when laser eye surgery risk is non existent given the rapid rate in which technology is advancing.

Eye surgery kept Ruas off the card, and the replacement was reportedly injured in training just a few days before the fight. Just be sure to ask about every little detail associated with it during your initial consultation as this all adds to the final laser eye surgery price bill.

If you meet the requirements, it also offers an increased probability that the resultant wave front lasik eye surgery will provide a successful outcome with fewer side effects.

Many people are taking advantage of this to travel to India save on eye surgery, get a free holiday and have money left over. On their web site, they advise people never to look for bargains when they are shopping for parachutes, scuba gear or laser eye surgery.

Lasik eye surgery cost has come down considerably in recent years.

With a lot of medical procedures in today’s world, the trends play an important part in deciding which procedure people get done. The trend of custom Lasik eye surgery is another such trend that is quickly dominating the world of eye surgery. With custom Lasik, you can pick the parts of the procedure that you want to have done. There are basics to Lasik eye surgery, but with the custom version of the procedure you are enabled a “say” in the way that the procedure will be done. The options for custom Lasik are available from most physicians that offer the eye procedure.

Now, in terms of this procedure it should be noted that the term “custom” does not necessarily refer to everything that we may be used to. Custom Lasik, in this case, allows you to take a look at your eye in a three dimensional way that allows the doctors to get a larger grasp of what the situation is and the type of procedural elements they will need to impress upon your eye. While the choice of custom Lasik eye surgery is yours in the end, the procedure gets more involved when you are able to use some of the more advanced technology. This only functions to further increase the odds of the success of your procedure in the long run.

Going With Your Instincts

In terms of getting Lasik eye surgery, whether you elect to try out the custom procedure or the traditional procedure, you will first need to be assured to be an actual candidate for the operation. This requires you to meet the fundamental requirements put forth by the Food and Drug Administration that will check your credentials and your medical history for any problems. If you are cleared for the procedure, you will be tested as to what procedural options are best for your situation and for your body. After this decision has been made, your procedure will be schedule with a trained physician.

In custom Lasik, should you elect to have it, your eye will be measured in a three dimensional fashion that will enable doctors to determine whether there needs to be any reshaping or other procedures. From there, you can pick those procedures and give the go-ahead for them or you can choose to do without. Regardless of your choice, the outcome ends up being up to you and the choices you make for your Lasik surgery.

For most of us who manage daily any level of compromised vision, our world is one where eyeglasses, contact lenses, pricey prescriptions, and frequent visits to the eye doctor are standard. But as Lasik surgery technology has continued to evolve and its popularity has risen exponentially, more and more people are choosing refractive eye surgery as an alternative to glasses and contacts.

Lasik surgery involves the reshaping of the cornea – the thin, transparent tissue covering the iris – or colored section – of your eye. The lens of the eye – which sits right behind the iris refracts – or bends – light rays so that they are seen by the retina – located in the back of the eye. The retina’s job is to then take these light rays and covert them to messages that can be understood by our brain’s optic nerve.

If you understand this process then you can understand that if our eyes suffer refractive difficulties, the light is not bent properly to the retina and the image that our brain receives is blurry. When we wear eyeglasses or contact lenses, the light is brought closer to the lens or sent directly to the retina. Lasik surgery uses laser technology to reshape the cornea so that light is refracted clearly.

During a Lasik surgery procedure, the patient is normally first given anesthetic eye drops to help numb the eye and minimize discomfort after which a speculum is placed on the upper and lower eyelids to prevent blinking. The eye is then immobilized using a corneal suction ring. After the eye is immobilized, a thin incision is made in the top layer of the corneal tissue, making a very thin flap in the tissue. When the flap is folded over, the second layer of the cornea – the stroma – is revealed.

Laser power is then used to resurface this part of the cornea. Such resurfacing is done based on what specific issues are apparent in your particular eye; information that is normally gathered during pre-surgical visits. After the reshaping, the flap is repositioned over the eye; healing takes place naturally and often very quickly.

Lasik surgery is a relatively quick procedure – usually completed in less than 20 minutes for both eyes – and most patients report that it is virtually painless; while it can be mildly uncomfortable at times. While vision may be blurry for up to a day following surgery, most people report clear vision after this time.

Lasik surgery, while popular, is not for everyone. In fact, a pre-surgical examination is imperative to determine if you are a good candidate for Lasik. Surgeons who perform Lasik normally look for at least six months of prescription stability in patients – meaning that your eyeglass or contact lenses prescription has remained the same.

In addition, refractive difficulties should fall under the appropriate guidelines for Lasik correction for the best chance of success. The doctor will also want to ensure that you are in good overall health.
