In order to truly comprehend the effect of laser eye surgery, we must first consider the vision anomalies that it treats. It is a general belief that common refractive errors, such as myopia, hyperopia and astigmatism, are attributable to certain irregularities in the shape of the cornea. Due to such anomalies, light rays entering the eye don’t fall exactly on the retina (a layer of light sensing cells) thereby resulting in unclear vision. LASIK is a surgical procedure that aims to rectify these irregularities by reshaping the cornea.

LASIK restores visual acuity through precise ablation of the corneal tissue with the aid of a high precision laser, an excimer laser, which is a “cool” laser that precisely carves the cornea without heating or damaging the surrounding tissue. Once reshaped, the cornea enables the desired accurate refraction, since the light rays now fall precisely on the retina.

Laser eye surgery imparts enhanced visual acuity, without the need for corrective lenses. With the superlative technology at its disposal, laser eye surgery provides excellent results that are rather impressive. An estimated 98% of patients are within 1 diopter of their refractive error following surgery, possessing unaided visual acuity of 6/12 or better. Over half of the patients achieve unaided visual acuity of 6/6, which is the standard visual acuity. However, visual acuity may sometimes be worthless if vision quality is sacrificed in process. Though rare, laser eye surgery complications like halos, glare and double vision may cause vision quality deterioration, rendering blurry vision.

The complications, if any, may be a source of discomfort. The use of prescription eye drops and artificial tear drops helps in soothing the eyes thereby averting the irritable feeling in the eyes that creeps up after surgery. These side effects are known to subside within a few months and the refraction stabilizes within 3 to 6 months following surgery.

Nevertheless, LASIK is a viable, safe and efficacious procedure. Its effects are permanent on the eyes. That is, the refraction attained lasts forever unless otherwise altered due to age related eye ailments, such as presbyopia, which is known to affect almost every individual in their mid to late 40s.

If you find a LASIK surgery that you are confident with, you will be able to get more information about the effects of LASIK laser eye surgery.

Often times called ophthalmic surgery, eye surgery, is a surgical procedure that is preformed on the eye or eye region. This type of surgery, due to it’s nature, is typically performed by an ophthalmatolgist; hence the original name ophthalmic surgery.

There is several different types of eye surgery. The most common are described below:

PRK (PhotoRefractive Keratectomy)

PRK surgery is when the most oustide layer of the cornea is scraped away manually and an excimer laser is used to reshape the tissues located underneath the surface of the cornea. After the corrective eye surgery is done the outer layer must be grown back, in order for the eye to be protected again. Due to this, PRK is known for having a large recovery time. There as some advanced methods avaiable today that use a different excimer laser which vaporizes the epthithelium, however it is not widely used.

LASEK (Laser Assisted Sub-Epithelial Keratomileusis)

LASEK is advanced form of PRK(see below) that uses an alcholic solution on the epithelium which softens the surface before it is removed. With this procedure the epithelium can be replaces once the surgery is finished.

Epi-LASEK

Epi-LASEK is similar to LASEK however it uses a type of barrier to preserve the epithelium layer, which is then replaced after the surgery. The reason for this extra step is to try and help cut down post surgery discomfort, and increase the amount of time required for healing.

As you can see their is several different methods of laser eye surgery; These aren’t even all of them! If you think that eye surgery might be right for you, or are interested in obtaining more information it is recommended to consult with your local physician and eye doctor.

Lasik’s is the term that is commonly referred to when most consumers are talking about laser eye surgery. The main reason for this procedure is to reduce a person’s need for either glasses or contacts to improve their vision.

The name LASIK is derived from a laser eye procedure named Laser-assisted In Situ Keratomileusis. The procedure consists of the use of an excimer laser that permanently reshapes the covering of the eye so a focused vision is obtained. There are two different types of blades that are used to cut the flap so the inner cornea can be reshaped. The mechanical blade is called a microkeratome and the laser is a keratome.

There have been five instruments that have been approved by the FDA since the year 2000. The latest is the MEL 80 Excimer Laser System by Carl Zeiss Inc was approved on August 11, 2006. This uses a laser that cuts at the wavelength of 193 nanometers.

The LASIK Eye Drape was developed by Odyssey Medical Inc and received approval on May 10, 2005. This was a new style of drape that is used to help protect not only the patient but also the surgeon.

Alcon Laboratories Inc had two approvals for their Wavelight Allegretto Wave Excimer Laser System on October 7th and 10, of 2003. The first one was for the system and the second was for the ophthalmic medical laser system that cuts at 193 nanometers.

Technolas GMBH Perfect Vision was approved for their Technolas 217A Excimer Laser System on February 23, 2000. This excimer laser is a class 3 medical device.

These are the latest FDA approved for the many Laski’s surgeries that are preformed around the United States. Check with your surgeon to see what he is using.

The question that goes through the mind of most every person considering LASIK eye correction surgery is whether or not it is safe. For those who don’t know, LASIK or “Laser Assisted In Situ Keratomileusis” is a type of vision correction surgery in which surgery is performed on the cornea of the eye using a laser.

Many who consider this surgery often have concerns of whether or not it is safe. Only through thoroughly understanding the procedure and the possible consequences can one make such a determination. LASIK surgery is most definitely not for everyone and knowing what makes you a good candidate can help you make that decision.

The first thing to remember is that LASIK surgery is a biological procedure and as with any biological procedure the human body may or may not accept it. This means that there is no one hundred percent surefire way to know that it will work or not. Needless to say, we as a society take these kinds of risks every day and may not even know it. For example, we drive to work every day and leave ourselves open to unsafe drivers yet we outweigh the dangers because it is important for us to get to work everyday to support ourselves.

Commonly, LASIK surgery is very successful. The amount of long term complications is less than half a percent. These odds are fairly great of a successful procedure compared to many other types of surgeries. The most common problems associated with LASIK surgery are as follows:

o Blurred Vision (temporary or long term)

o Loss of eyesight (or may be worse than before)

o Over correction or under correction

o Inability to drive at night due to night blindness

Most of the complications listed above may be treated with additional surgical procedures and are fairly uncommon for the most part. LASIK surgery on the other hand have given people eyesight with as good as 20/20 vision and given people a chance to see without the help of contacts or glasses. Who seems to make a good candidate for LASIK are those who’s vision have impaired them from normal day-to-day functions. This often justifies the reason for getting such a surgery. Many surgeons usually recommend these types of patients over the ones strictly wanting a type of cosmetic surgery in which they no longer have to wear glasses. Knowing this can help you decide whether or not the risks are greater than or less than the value of a successful LASIK procedure.

Lasik Eye Surgery

Laser eye surgery can change the lives of those who choose it as a method for vision correction. The treatment can be used on people with varying levels of vision problems, even if they are very slight or very extreme.

However, there are several different types of treatment out there and this can get confusing because we can get overwhelmed with what’s on offer. What’s more, the thought of laser eye surgery is fairly frightening to some, so a blur of information is not very helpful when it comes to feeling better about the procedure.

One of the most common types of laser eye treatment is LASIK, which stands for Laser-Assisted-In-Situ-Keratomileusis. This procedure is performed many times every year with a high level of success and only takes around ten minutes to carry out, treating both eyes at the same time. During LASIK treatments, the eye is anaesthetised before a protective flap is lifted from the surface, revealing the inner corneal tissue. This tissue is then worked on by the laser, which reshapes the surface until it is corrected. The protective flap is replaced and left to heal.

Most patients report an improvement in vision within hours of this treatment, and many say that the levels of discomfort following the surgery are minimal. The eyes heal quickly and patients usually return to work within a couple of days.

LASEK stands for Laser-Assisted-Epithelial-Keratomileusis and is used to correct long and short-sightedness, as well as astigmatism. LASEK surgery involves the removal of the top layer of the cornea following the anaesthetising of the eyes. This layer is then sculpted by the laser to correct long and short-sightedness or astigmatism before being replaced and left to heal. Following LASEK, surgeons will place a soft contact lens on the eye to protect it and promote comfort.

LASIK is carried out more frequently than LASEK as it tends to have a faster recovery time. However, some patients are better suited to LASEK because they may be involved in contact sports or have thin corneas, for which LASEK is a better treatment.

IntraLase provides an alternative way to create the protective flap before LASIK surgery. It involves a laser being utilised in the creation of the flap and promotes even faster healing time.

If you are thinking about getting laser eye treatment, you will always have to undergo an in-depth consultation first – so you’ll never have to worry about getting the wrong treatment. However, it’s useful to know a little beforehand so you are prepared for the consultation and what will come up.

Cataract is a disease that is in the way of your sight. This dilemma is to move on whenever the normal eye of a person probably has always been clouded with unnecessary components. In general it manifested at the back of the sclera and the iris of the eye. Situation associated with severe infection will bring to a cataract surgery. Even if medical procedures are the main option to get rid of the cataract condition, however, have several complications that further damage to the person. Persons who need special attention on the operation and surgery are those who have accumulated from a certified medical practitioner.

Harmless attacks and eye infection as a result of medical procedures can lead to serious problems. The thought is, of course, if the course of action was performed by a fake surgeon. Actually everything after the opacity of the capsule is actually a barrier that develops when discovers he has an infection in his vision, eye irritation, eye contact and more dislocated. It has particular attribution, like having a dark and cloudy vision in spite of medical procedures that have already completed. Membrane layer tablets can not be borne by an artificial intraocular lens, it is constantly useless.

It is generated by the actual spread of infection through cataract eye balls that can be lasting contacts within the substance of epithelial cells was established on the membrane or tablets, which also degenerates your difficulties contrast with the past. When your cataract disease has been careful to spread around specific areas of your eyes, it is really hard to be a medical procedure to make extra. Retinal dilemma is a few weeks or maybe several years before a fully successful process of cataract surgery. Although the process has been the money-spinning, it is very likely that the report conditions related to concerns that the inflammation of the cornea or retina.

There is also demand pleasant to the eyes, causing sequentially tired eyelids. The purpose of cortisone through the entire process may take as a cause of these diseases. The symptoms and signs of this complex tend to double or perhaps distorted and the phase sensitivity to bright light is pretty sweet.
