Information on Corrective Eye Surgery

Information on Corrective Eye Surgery

Several types of correct eye surgery exist today and these different types of corrective eye surgery fall under two main categories: Excimer Laser procedures and Non-Excimer laser procedures. As is the case with other conditions that affect the body, major technological advances have been made in recent years in the field of corrective eye surgery. The following is a brief introduction to the two categories.

Excimer Laser Procedures

An Excimer laser is a tool that was approved for the treatment of nearsightedness ranging in severity from mild to moderate. Use of the Excimer laser is complicated and it's important to work with ophthalmologists who are both trained in the surgical procedure and who have demonstrated the ability to properly operate and calibrate this precision instrument.

The Excimer Laser was originally approved for PKR, or Photorefractive Keratectomy and its usage was later expanded for LASIK procedures, or Laser in situ Keratomileusis. With PKR, the cornea is reshaped by eliminating excess tissue from the cornea's outer surface. With each computer calculated lightening-fast laser pulse, a microscopic ultraviolet light beam removes the excess tissue. After only a few minutes and the application of local anesthesia, the procedure is over. In just a day or so, patients can resume normal activity.

In a LASIK procedure, the eye doctor rather than the laser's built-in computer determines where incisions will be made and how much tissue will be removed. This is a more complex and invasive procedure and it is one that is recommended for more severe refractive conditions. Using a microkeratome (a knife), the eye surgeon slices and then pulls back a flap of the tissue covering the cornea. With the tissue out of the way, the laser is then used to remove tissue and reshape the cornea. The flap is put back into place and the patient typically can see well enough to drive home after the procedure. LASEK and epi-LASIK are variations of the LASIK procedure.

Non Excimer Laser Procedures

These are procedures that rely on artificial implants, surgery and reshaping to correct eye problems. Lens implants are effective for individuals who have cataracts, nearsightedness and farsightedness. Intraocular lenses or IOLs are used as replacements for the damaged cloudy lenses caused by cataracts. New and improved artificial lenses now incorporate the use of hinges that allow the eye to move and act like a real lens.

Other types of implantable contact lens can correct nearsightedness and farsightedness. They act much like removable contact lenses but require no maintenance and wearers cannot feel these lenses and implants.

Thermokeratoplasty involves the use of heat to manipulate the collagen within the cornea. In doing so, refractive errors can be corrected in a matter of minutes. There are two types of Thermokeratoplasty procedures. Laser thermal keratoplasty or LTK involves the use of holmium YAG laser and CK or conductive keratoplasty involves use of radiofrequency waves.

Astigmatic Keratotomy (AK) involves cutting the cornea in order to reshape it. However, its use has diminished since laser treatments involve less risk and are far more effective at reshaping the cornea.

Questions about Lasik eye surgery

Questions about Lasik eye surgery

Many people that wear glasses or contact lenses have listened to the claims of how Lasik can give them perfect vision.  They have also heard great Lasik success stories, as well as stories from people that were not sure they had given the decision enough thought.  This guide lists the most common questions asked by people who are considering Lasik vision correction, and answers given by reputable physicians.

The first and most important question asked about Lasik is, not surprisingly, "Is Lasik safe?"  The answer is that it is normally quite a safe procedure, with success rates above 95 percent for good, experienced Lasik surgeons, and 90 percent average over all physicians that perform the Lasik procedure.  This statistic about Lasik success assumes that the patient is a good candidate for Lasik surgery.  The requirements have some specific details and should be gone over with the physician that will perform the Lasik procedure.

It is a very good idea to ask the Lasik physician which patients he has declined to perform the Lasik procedure on, to make sure that the particular physician has and operates with good standards.  Any Lasik practitioner that tries to imply that everyone that comes in to his office is a good candidate for Lasik vision correction should be viewed with some skepticism.  In any case, it is wise to interview several different physicians that perform the Lasik procedure before deciding on one.

A second frequently asked question about Lasik is "What are the possible complications from Lasik surgery?"  Common side effects are starbursts or halos when looking at a light, sensitivity to light and difficulty with glare and night vision, and some sensation that a foreign body is in the eye.  Most of these effects will pass within a few days after the Lasik procedure.  Between 1 and 3 percent of patients will have a lasting side effect such as halos or some vision fluctuation.

It is a very good idea to discuss your particular situation with the Lasik physician to determine if you might be prone to any complications.  There are also variants of the standard Lasik procedure, one of which uses additional waveforms to map out an individual eye, or techniques that only use lasers rather than a scalpel and a laser.

One question we all hesitate to ask is "Will the Lasik procedure be painful?"  Since our eyes are one of the most sensitive parts of our bodies, it is comforting to know that having Lasik vision correction is usually nearly painless.  There is often some mild discomfort after the procedure, but this is effectively controlled with medication.

"Will I have 20/20 vision once the Lasik correction is done?"  Though many patients do get nearly perfect vision, not all patients have their vision totally corrected.  You can definitely expect to have improved vision and minimized dependency on any glasses or contacts.

"What is the cost and how do I pay?"  A typical Lasik surgeon charges between $500 and $2500 per eye, depending on the patient and the surgeon.  However, a Lasik physician should be selected on experience level and track record, not on the lowest price.  Insurance rarely covers the cost of Lasik, but many Lasik centers have a type of financing program offered to their clients.

Consider Lasik eye surgery as one way to significantly improve the quality of your life.

Is LASIK Surgery an option for you?

Is LASIK Surgery an option for you?

Many patients are very satisfied with the improved quality of life that they experience after LASIK Surgery. Read on to decide whether LASIK Surgery is right for you. 

The different types of LASIK Surgery

There are two basic types of surgery: Standard LASIK and Custom LASIK. With either type, the preparation work and post-operative procedures are similar. The difference between the procedures involves the customization of the laser.

Standard LASIK

Prior to the scheduled procedure date, the eye surgeon meets with patient to re-test for certain eye problems and diseases. When it's confirmed that the patient meets the requirements, a procedure date is set.

On the day of the procedure, the eye doctor may perform another corneal topography to confirm that nothing has changed that would require changing the procedure. Three types of eye drops are then administered. The drops anesthetize the eye, protect the eye from post-operative inflammation and protect the eye from infection.

Next, the patient reclines and the laser is positioned overhead with the eye surgeon above it. To remove the flap, the patient's eye must first be stabilized. The eye is kept from blinking by placing it into a restrainer. Suction is administered to the eyeball and the microkeratome makes one swift slice across the top of the cornea. The resulting flap (which should still be hinged to the eye) is pulled away with tiny tweezers.

The laser then emits a pre-determined number of laser pulses to remove the excess tissue, a process which takes literally seconds. The flap is pulled back into place and saline solution clears the eye of any debris. The eye is covered and the procedure is finished unless the other eye is receiving a LASIK Surgery treatment.

Custom LASIK Surgery

In standard LASIK, the computer inside the laser determines the number and location of laser pulses based solely on the patient's prescription. With custom LASIK, the eye surgeon creates a three-dimensional image of the eye. The image results are then fed into the laser's computer and the patient receives a laser treatment that is truly customized to that eye.

Risks and complications

As with any surgical procedure, there are risks associated with LASIK Surgery. The procedure may under- or over-treat the eye. Under-treatments can be corrected with additional surgery however over treatment generally results in the patient needing to continue wearing corrective lenses. Loss of vision or compromised vision, especially at night, are other risks. Dry eye syndrome can develop. And vision that has been surgically corrected may decline over time. Another serious risk involves using an inexperienced ophthalmologist.

Tips on selecting a LASIK Surgery surgeon

Get referrals from people you trust and then make arrangements to interview several candidates.

Make the most of the pre-procedure consultation. Prepare a list of questions to ask each surgeon and record the answers. It's important to understand what care the ophthalmologist intends to provide during all stages of surgery: before, during and afterwards as well as all costs.

Remember that low cost doesn't mean top quality. Your eyesight is far too valuable to allow cost to be the determining factor.

Solving a Lasik Post Op Problem

Solving a Lasik Post Op Problem

I had Lasik vision correction surgery two years ago, and am quite glad I did.  I think that my Lasik story might be helpful to some that consider that they might not be a perfect Lasik client, and are concerned about side effects after the Lasik procedure.  I did have a significant side effect after my Lasik operation, but have weathered it well, and still recommend the operation highly.

My operation went exactly as described, with no pain or real discomfort at all.  My Lasik physician was clear, stating each step that he completed so that I would know the Lasik procedure was proceeding as expected, and more quickly than I had imagined.  I know that all of the discussion I had earlier with the Lasik professionals stated the operation generally took less than twenty minutes, but I was still surprised.  

At the end of the operation, my Lasik doctor replaced the flap to its correct position in my eye and covered it with some kind of clear goop.  Even at that time I could notice a distinct improvement in my vision.  I was instructed to wear goggles over my eyes for five nights in order to prevent me rubbing my eyes while I was sleeping.  I guess they assumed that any good Lasik patient would not do that when awake.  

In addition, I followed all post-op Lasik procedure instruction to the letter.  I slept immediately after the Lasik procedure was done (after I made it home, of course), used the eye drops religiously, and did not try to strain my eyes by reading everything that I could.  I was amazed the immediate improvement in vision that Lasik makes, just as if there was a set of weightless contact lenses.  Very impressive.

My biggest problem in Lasik procedure recovery was a result of epithelial erosion.  The flap that is made in the eye during the Lasik procedure is made from epithelial cells.  Once the flap is replaced at the end of the Lasik procedure, these cells start to regenerate in order to fill in the line where the flap has been cut.  All of this is normal post-op Lasik healing.  However, in my case the cells would grow fine, but at night my eyes tended to dry out when I was asleep.  So, when I woke up, my eyelid would pull up some of the new cells from their place where they belonged, where if my eye was sufficiently moist they would have stayed in place.

I told this to my Lasik eye surgeon, who said this side effect just makes healing a little longer and it was not a serious side effect.  When I went for a checkup to the Lasik center (which I highly recommend any time a Lasik client has any post-op worries or questions) they decided that I needed a thicker, more jelly like version of the eye drops to use at night.  This worked well, and the rest of my post-Lasik recovery went well.  
I am a strong advocate of the Lasik vision correction procedure.  I also strongly suggest interviewing a number of positions, and do not put low cost as the highest priority.  Your eyes are very important, and a highly competent Lasik physician is the most important factor.

Eye care after lasik surgery

Eye care after lasik surgery

A person that is considering a Lasik procedure to improve their vision has two major responsibilities: selecting the best surgeon possible for their budget, and understanding and keeping up with eye care after the Lasik operation is done.  Most Lasik procedures go very smoothly, and more than 90% of the patients are happy with their improved vision and have no permanent side effects.  Part of this success is due to good care at home once the Lasik procedure is complete.

The first step in having the best care after a Lasik procedure is to understand exactly what is directed by the Lasik physician.  The prospective Lasik patient should be given a good understanding of the entire process when they first visit a Lasik center to interview the physician and the staff.  On the day of the procedure, a member of the staff should very carefully go over exactly what steps should be done to encourage optimal eye health and healing after the Lasik operation.

One thing that the patient should ask is what side effects are to be expected directly after the Lasik procedure, how long they should last, and which symptoms should be promptly told to the Lasik physician or member of the staff.  A number of symptoms, such as fluctuating vision or halos around lights, are to be expected and are not a cause of worry.  Ask the staff about any postoperative symptoms that are unclear, to make sure that they are thoroughly understood.

Each Lasik physician has their own recommended procedures for their patients, but here is a list of typical suggestions that most Lasik centers recommend.  First, get some sleep as soon as possible after the Lasik procedure is done.  This gives a great boost to the healing process.  Second, avoid any contact, bumping, or rubbing of the eyes for at least five days after the Lasik procedure.  Most Lasik eye surgery centers have some kind of eye guards to wear at night to prevent patients from rubbing their eyes in their sleep.  

Third, try to avoid eyestrain for some days after the Lasik procedure.  It is tempting to try to read all of the signs and words that were previously blurry, but avoid this temptation at least for the large part.  If any light sensitivity or glare is noticed, wear dark sunglasses for several days until this problem resolves itself.  Some common Lasik side effects are temporary halos around lights, especially when viewed at night, but this is not a problem to be concerned with.

It is very important to keep the eyes well lubricated in the days following a Lasik operation.  Every Lasik physician will give eye drops to help this, and patient should be especially aware of this before going to sleep.  A Lasik procedure may increase eye dryness temporarily, and during sleep this may make the eyelid stick slightly to the eye.  When the patient wakes up, opening the eyelid is equivalent to rubbing the eye.  The physician should be notified if this happens, for there are other varieties of eye drops that will solve this problem.

Taking these simple steps will give nearly all Lasik patients an easy postoperative experience without any problems.

Have no fear of Lasik eye surgery!

Have no fear of Lasik eye surgery!

Thinking about eye surgery using a Lasik procedure is a big step, and many people are a little hesitant to ask the questions that they have.  The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown.  This report addresses some of the more commonly held fears, and talks about the experience for the vast majority of people that undergo a Lasik procedure.

A most common fear when thinking about a Lasik procedure, or really thinking about any surgery in general, is the possibility of pain during or after the operation.  Since the Lasik surgeon works on patients that are conscious, this is a widely held apprehension.  In every operation the Lasik surgeon applies numbing drops into the eyes before the procedure starts, and the patient is also given a mild sedative to relax them and make sure that they are comfortable.   Though a small pressure to the eye may be felt during the Lasik procedure, the process itself is relatively pain free.

The surgeon does use a laser in the eye to help reshape the cornea during the Lasik procedure.  Many folks are worried about the laser being shone directly into the eye, or that they might look away and, due to this, develop a serious complication with their eyes and the Lasik laser beam effects.  In actuality, the laser is only active for ten to fifteen seconds for each eye, and the Lasik machine has a tracking system that allows the beam to be on only when the eye is in the correct position.

Another general fear for people contemplating a medical procedure is fear of "the scalpel".  Any Lasik procedure uses only a very small microkeratome blade to approach the eye, or some more recent Lasik innovations have the laser itself created the flap and avoid using any hard surface at all.  There is no reason to be concerned about a scalpel, for the Lasik physician does not use one.

Many wonder about the horror stories they hear about this or any other operation, and wonder about serious consequences like going blind.  According the government statistics taken by the FDA, there are no reported cases of blindness due to a Lasik operation.  Actually, the risk of a serious permanent complication due to the Lasik procedure is less than 1 percent, and the risk of any permanent complications even if not serious (such as light halos) is 3 percent or less.  It is extremely rare for a patient to not have improved vision after a Lasik procedure.

If the thought of being awake and having your eyes open during the Lasik procedure bothers you, remember that you will be given a mild sedative for the procedure, and that your eyes will have numbing drops administered to them.  If the thought of actually seeing the Lasik physician's hand approaching your eye is bothersome, be comforted that the surgeon applies drops to the eye that blacks out the vision in that eye for ten to fifteen seconds, which is long enough for the procedure to be done for that eye.

This introduction has hopefully addressed the most common fears about the Lasik procedure.  For anyone that might gain a better life quality with improved vision, please visit your local Lasik eye surgery  clinic and discuss the procedure in detail with the professionals there.

Costs Involved With Laser Eye Surgery

Consideration of the size of your eyesight would be done if you were expecting a good result after laser eye surgery. Nevertheless, a size of eyeballs is a factor of agin and is often referred to as the process of getting more mature. The size of the eyeballs in this respect determines if the positioning of the cornea if laser light were beamed on it.

It is good you expect the unknown in terms of possible complications from laser eye surgery. Once you put in your guard against such, you will never be taken unaware. This state of mind will enable you to heal faster and get the restored eyesight you have ever wanted.

Do you have a vessel sickness? If yes, I think you better stop considering laser eye surgery as an option in treating your eye disorder. This could genuinely be serious for you and very severe. Remember that your eye is the most important part of your body. So do not play with it. Refraining from laser eye surgery if you have this problem is a wise choice.

You went to a doctor and he recommends that you need to undergo laser eye surgery in order to correct your eye disorder. How will you absolve this news? Well, it is imperative that you know what in essence is laser eye surgery. In a simplistic way, having surgery on your eyes using laser is a medical operation performed on patients who have myopia, hyperopia or astigmatism. The procedure is basically to correct these disorders.

Compare with other types of surgeries; the improvement that you will have on your eye sight after laser eye surgery is short. You should be able to get your required vision back at least three days after the procedure. However, your ability to heal fast will still depend on you abiding by the post surgery instructions.

You can use the Internet to get all the information you want to know regarding laser eye surgery. Make sure you take a break and make your research. Throughout your research you will come in contact with links that will allow you to visit sites that will mention places where this type of surgery can be performed. Also, the quotes from different specialists could be available for your comparison.

Unlike any other type of laser eye surgery, LASIK type has far more benefits than the others. The used of this method will permanently correct your disorders. Moreover, by the result achieved, you will not have the need to worry about the buying and maintenance of contact lenses.

Having an eye examination carried out on you by your surgeon is a necessity you must be aware of as a pre-requisite for laser eye surgery. If your physician did not do this step; he might missed it or your should check his capability. The chance of a successful surgery is in your hand.
