The Different Types Of Eye Sugery

Wednesday, May 31st, 2006

 

Types of Eye Surgery

Eye surgery, also referred to as ophthalmic or ocular surgery, is a type of surgical procedure that is performed on the eye or the surrounding tissues. There are a number of different types of eye surgeries including refractive surgery, corneal surgery, glaucoma surgery, cataract surgery, and oculoplastic (cosmetic) surgery.

Refractive surgery

The goal of refractive surgery is to improve a patient’s vision. An individual who is either nearsighted or farsighted has a refractive error in the interior of their eye. Light entering the eye does not properly focus on the retina, instead focusing in front of the retina in nearsighted individuals or behind the retina in farsighted individuals. The result is that viewed images appear blurry and out of focus. Refractive surgery corrects this error, allowing light to focus directly on the retina, thereby improving vision and eliminating the need for corrective lenses.

There are numerous methods of refractive surgery, the most popular of which are LASIK (laser assisted in-situ keratomileusis), LASEK (laser assisted sub-epithelial keratomileusis) as known as Epi-LASIK, PRK (Photorefractive keratectomy), CK (conductive keratoplasty), and ICRs or Intacs (Intracorneal rings).

Corneal surgery

Corneal surgery is any surgery that involves manipulation of the cornea of the eye. This encompasses nearly all types of refractive surgeries since the cornea is modified in order to improve the individual’s vision. It also includes corneal transplant surgery, a procedure by which a damaged or diseased cornea is removed and replaced with a clear cornea from an organ donor. Other types of corneal surgery are PK (penetrating keratoplasty), PTK (phototherapeutic keratectomy), and Pterygium excession.

Glaucoma surgery

Glaucoma is a disease that attacks the optic nerve, resulting in loss of vision and a rise in intraocular pressure. Glaucoma surgeries assist in combating the disease by lowering intraocular pressure. This may be accomplished by decreasing the amount of aqueous produced in the eye or by encouraging the release of excess aqueous humor from the eye.

Cataract surgery

Cataract extraction is the most common eye surgery performed. Age, illness, or trauma to the eye can sometimes cause the crystalline lens of the eye to become cloudy and opaque. This cloudiness, called a cataract, interferes with the eye’s ability to focus a clear image on the retina, resulting in loss of vision. The presence of significant cataracts requires the removal and replacement of the lens through cataract surgery. Although there are a number of different types of cataract extraction, the two most popular procedures are called ICCE (intracapsular cataract extraction) and ECCE (extracapsular cataract extraction).

Oculoplastic surgery

Oculoplastic surgery is a type of eye surgery that concerns the reconstruction of the eye and its surrounding structures. Eyelid surgery, or blepharoplasty, removes excessive fat, muscle and skin from the eyelid to correct sagging or puffy eyes. Browplasty, often referred to as a brow lift, is the reconstruction of the forehead and brow bone. Oculoplastic surgery can also involve the removal of the eye itself. Enucleation involves the removal of the eye itself, leaving the muscles surrounding the eye and all orbital contents in place. Evisceration occurs when the eye and all of its contents are removed, leaving just the shell of the sclera in place. Finally, exenteration involves the removal of the entire orbital content. This includes the removal of the eye itself, any extraocular muscles, surrounding fat, and all connective tissues.

Laser Eye Surgery And The Epithelium

Monday, May 29th, 2006

 

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.

What Is Refractive Eye Surgery?

Sunday, May 28th, 2006

 

Refractive eye surgery is a type of eye surgery that is used to rectify refractive errors of the eye and decrease dependency on corrective lenses such as eyeglasses and contact lenses. Successful refractive procedures can reduce myopia or nearsightedness, hyperopia or farsightedness, and astigmatism or elongated corneas. A number of different procedures exist for refractive eye surgery depending upon the type and severity of the refractive error.

There are four main types of refractive eye surgery procedures: flap and photoablation procedures; corneal incision procedures; thermal procedures; and implants. Currently, the most common refractive eye surgeries involve the use of lasers to reshape the cornea.

Flap procedures involve cutting a small flap in the cornea so that the tissue underneath can be reshaped to correct the refractive error. LASIK, short for Laser Assisted In-Situ Keratomileusis, is the most popular refractive surgery and is used to correct myopia, hyperopia, and astigmatism. The LASIK procedure involves using a microkeratome or IntraLase to cut a flap into the stroma, moving the flap out of the way, removing excess corneal tissue with an excimer laser, then replacing and smoothing out the flap. LASEK is best suited for individuals with thin or flat corneas. The LASEK procedure uses a small trephine blade to cut into the shallow epithelium, after which the eye is bathed in a mild alcohol solution to soften the edges of the epithelium. The flap is gently moved out of the way so that an excimer laser can remove excess corneal tissue, after which the flap is replaced and smoothed out. Epi-LASIK, like LASEK, involves a shallow cut into the epithelium, but makes use of epikeratome to create a thin epithelium sheet for removal instead of the harsher blade and alcohol.

Photoablation, the second stage in flap procedures, makes use of ultraviolet radiation to remove excess corneal tissue. PRK, or photorefractive keratectomy, was the original laser eye surgery procedure. PRK involves numbing the eye with local anesthetic eye drops, and reshaping the cornea by destroying miniscule amounts of tissue from the surface of the eye. The laser used, an excimer laser, is a computer-controlled ultraviolet beam of light. It burns cool so as not to heat up and damage the surrounding eye tissue.

Corneal incision procedures such as radial keratotomy and arcuate keratotomy use miniscule incisions in the cornea to alter its surface and correct refractive errors. Radial keratotomy, or RK, uses a diamond tipped knife to make a number of spoke-shaped incisions in the cornea. The result of the incisions is that the cornea flattens out, minimizing the effects of myopia. Arcuate keratotomy, or AK, is very similar to RK. The diamond knife is used to cut incisions that are parallel to the edge of the cornea, as opposed to the spoke-shaped incisions of the RK procedure. These procedures have been much less common with the emergence of laser-assisted refractive eye surgeries.

Thermal procedures use heat to correct temporarily hyperopic refractive errors, or farsightedness. The thermal keratoplasty procedure involves putting a ring of 8 or 16 small burns on the eye immediately surrounding the pupil. The application of the heat increases the slope of the cornea, making it steeper, through thermal contractions. There are two main types of thermal keratoplasty. Laser Thermal Keratoplasty, or LTK, is a no-touch procedure that uses a holmium laser. Conductive Keratoplasty, or CK, uses a high-frequency electric probe.

The final type of refractive eye surgery involves the use of implants. Implantable contact lenses, or ICL, can be used to correct severe levels of myopia, hyperopia, and astigmatism. The implants are actually tiny contact lenses that are inserted through a small incision in the side of the cornea. Implants are seated so they sit immediately in front of the eye’s natural lens just behind the cornea. ICL works in conjunction with the eye’s natural lens to refocus light on the retina and produce a crystal clear image.

Each of these procedures has its advantages and disadvantages, and not all individuals are suitable candidates for refractive eye surgery. Individuals who are interested in learning more about surgical options should contact their ophthalmologist for more information about these procedures, as well as inquire about other new cutting-edge procedures. Since ophthalmologic surgery is constantly growing and changing with emergence of new technologies and methods, there are always new techniques in development. As new equipment is developed and methods refined that can improve the success and minimize the side effects of refractive eye surgery, new procedures will emerge to replace outdated techniques.There are many reasons why you can be losing your hair. There are many causes of hair loss that include stress, poor diet, ALOPECIA or genetically related. Male pattern baldness is a popular term used where you can see a man’s hairline go back. Often experts state that this is an inherited state. How this begins is often with a receding hairline and thinning on the top of the head. Depending on the severity of hair loss, there are definitely treatments out there.

Types of Vision Correction - Which Is Right For You?

Friday, May 26th, 2006

There is no dearth of options when it comes to vision correction. Several types of vision correction techniques have emerged in the recent years, with each year witnessing the birth of a new set of vision corrective procedures. Furthermore, many of these techniques are safe and reliable. Even amidst a lot of options, laser eye surgery is the preferred eye corrective surgery. Prolific technology has lead to the invention of improved lasers, which boast of immensely high precision. Such advanced technology ensures that laser eye surgery retains its top spot among corrective eye surgeries and remains a safe procedure.

Another option for eye correction is lens transplant. This is a popular alternative to laser eye surgery. Essentially, lens transplant is the same as cataract extraction, where the faulty lens is extracted and a clear intraocular lens is implanted. Though this procedure can be used to treat many types of vision impairments, it is highly beneficial in case of farsightedness (with a high refractive error).

Let’s face it. Not everyone is comfortable with a surgical procedure. For years now, people have donned spectacles or contact lenses to correct their vision impairments. Spectacles and contact lenses are a much safer proposition than a surgery, and pretty much affordable as well. With spectacles coming in great styles and designs, they could well be a strong fashion statement for you. If your job involves substantial field work, or you are the sporty type, you would rather go in for contact lenses. Spectacles and contact lenses are a simple and affordable alternative to surgery.

Only you can be the judge of which alternative to choose. Carry out a basic research, thoroughly examine and discuss your case with an experienced doctor, and then only decide on what procedure can be the best bet for you. Eyes are precious, so don’t jump on any conclusion without carrying out sufficient research.

Facts About Lasik Laser Eye Surgery

Wednesday, May 24th, 2006

A popular procedure is lasik laser eye surgery which is intended to reduce your dependency on either your eyeglasses or contact lenses.

This is dedicated to providing you with the knowledge you need when considering laser eye surgery. This procedure can be a bit intimidating for people and hopefully you will feel much more comfortable about it once you have read this. A popular procedure is lasik laser eye surgery which is intended to reduce your dependency on either your eyeglasses or contact lenses. Your best bet to get fully informed before having laser eye surgery is to go for an evaluation with your optometrist to see if you are a potential candidate for laser vision correction. Before moving forward you want to ensure that you are fully informed about the procedure.

Prior to the evaluation with your optometrist, stop wearing your contact lenses and only wear you eyeglasses for a minimum of 2 weeks before your appointment. Contacts actually change the shape of your cornea. By wearing eyeglasses only, your corneas ill go back to their natural shape. After your evaluation, your doctor will be able to determine if you are a good candidate for lasik
laser eye surgery or any other laser eye surgery. They should then explain fully all the risks, benefits and other alternatives to laser vision correction. If you are unsure about anything, it is extremely important that you ask your doctor so that you are making a fully informed decision.

Laser eye surgery is virtually pain free as the cornea is anesthetized using special drops. There may be mild discomfort when the anesthetic wears off but this irritation should be minor and last only a few hours. Laser vision correction is a very quick procedure which can take between 15 and 40 seconds. Most patients notice an improvement within 3 to 5 days of having laser eye surgery. So whether you choose lasik eye surgery or any other type or procedure, make sure to do your research and consult a reputable clinic. It is critical that before undertaking anything like this, you are well educated and can go in with confidence.

See Your Way To Lasik Laser Eye Surgery

Tuesday, May 23rd, 2006


Before you decide to have Lasik Laser Eye Surgery, you should do some research on both the type of surgery and the doctor who you want to perform it.


Electing to have corrective surgery on your eyes can be a great way to free yourself from the daily grind of constantly cleaning off and adjusting your glasses or cleaning contact lenses. This type of corrective surgery is quite common these days and considered safe. Before you decide to have this procedure, you should do some research on both the type of surgery and the doctor who you want to perform it.

Types Of Laser Eye Surgery: Before you pick your Lasik Laser Eye Surgery Newark location, you should look at the different types of procedures. Three type of surgery you may want to consider include:

• LASIK or Laser-Assisted In Situ Keratomileusis is the most well known. This surgery cuts a flap in the cornea and reshapes it by removing tissue. It is a fast procedure with healing in a day or 2 and immediate improvement in eyesight.

• PRK or Photo Refractive Keratectomy is the procedure that has been around the longest. Cells are removed from the cornea to reshape it and improve vision. It has a healing time of a month and vision improvement is not immediate but gradual over time.

• CK or Conductive Keratoplasty is a fairly new procedure. Uses radio frequency energy applied with a hair thin device to reshape the cornea. It is an extremely quick procedure with very quick healing.

Risks

Although most people are good candidates for corrective eye surgery, some should not undergo the treatment or it may seriously impair their vision. For this reason, you should discuss having the surgery at length with your doctor who should advise you of any risks and evaluate your situation to insure the surgery is safe for you. In rare cases your vision could become severely impaired, so it is important to get a thorough evaluation and disclose all health issues to your doctor. Other risks include fuzzy vision, irritation of dry eye syndrome and loss of clearness of vision.

Benefits

Being about to see without the aid of contacts or glasses is wonderful! Imagine waking up and being able to see beyond the end of your bed? There are many everyday benefits to having your vision restored. Without having glasses or contacts in the way, it is much easier to be active and play sports. Plus you’ll never have to worry about breaking or misplacing your glasses or contacts or incur the yearly expense for new prescriptions.

Obviously, you should take any procedure involving your eyes very seriously. Make sure you put a lot of consideration into the procedure and doctor you want to restore your vision.

Laser Eye Surgery - There Are Four Types

Monday, May 22nd, 2006



While it is true that LASIK Laser Eye Surgery is a type of laser eye surgery, there are a number of other laser procedures that can produce equally successful results.


When most people think of laser eye surgery, they automatically think of LASIK. While it is true that LASIK is a type of laser eye surgery, there are a number of other laser procedures that can produce equally successful results for individuals suffering from myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. In fact, there are actually four different types of laser eye surgery:

PRK, LASIK, Customized LASIK, and LASEK.  PRK, or photorefractive keratectomy, makes use of a specialized cool laser beam, called an excimer laser, to remove excess corneal tissue. The removal of this tissue corrects the shape of the eye so that light entering the eye can be properly focused on the retina. The outer surface layer called the epithelium, is removed to expose the underlying corneal tissue. Once this tissue is revealed, the excimer laser is used to reshape the cornea. The main distinction between PRK and LASIK is that PRK does not make use of a corneal flap. Instead, the epithelium is allowed to gradually heal through the body’s natural healing process. To protect the exposed cornea, surgeons fit patients with a lightweight contact lens to serve as a bandage for the eye. The contact lens also reduces discomfort. The lens is usually only worn for a few days, two to three days post-operative, at which time the eye is allowed to heal as normal with no bandage.
LASIK is the most widely known and performed type of laser eye surgery in the United States. LASIK stands for Laser Assisted In-Situ Keratomileusis, which literally means to “reshape the cornea from within using a laser.”

LASIK differs from PRK in that a small flap is made in the stroma of the eye. This flap, made by either a microkeratome or IntraLase, is then peeled back to expose the underlying corneal tissue. An excimer laser is then used to reshape the cornea to correct any refractive errors. Once the cornea has been reshaped, the cornea flap is put back into place and smoothed out. The flap acts as a natural bandage to help the eye heal and protect the delicate cornea. The benefit of LASIK is that the use of the flap helps the cornea heals more quickly than it would using the PRK technique, and reduces much of the discomfort felt during the healing process.

Many ophthalmologic surgeons are now offered the next evolution in LASIK surgery, which they called Customized LASIK. The general procedure used to correct refractive errors is the same as is used for traditional LASIK procedures, with the addition of wavefront devices used to map the unique surface of the patient’s eye. The wavefront device passes a narrow ray of light through the systems and into the eye, measuring any optical distortions that result as the light exits back out the eye. Any irregularities identified are then fed back into the system so that the laser can automatically correct for aberrations on the surface of the eye. Proponents of Customized LASIK claim that the use of wavefront technology enables surgeons to treat higher order aberrations that can contribute to low-light visual disturbances such as halos and glare not corrected by traditional LASIK, eyeglasses, or contact lenses. Customized LASIK can provide patients who suffer from higher order aberrations with an increase in visual clarity.

The final type of laser eye surgery is LASEK, or Laser Assisted Sub-Epithelial Keratectomy. LASEK is especially helpful for patients who have a thin or flat cornea, making them questionable candidates for LASIK and Customized LASIK procedures. During LASEK, a small trephine blade is used to cut into the outer skin of the eye, called the epithelium. Once the cut has been made, the eye is bathed in a mild alcohol solution to allow the edges of the epithelium to soften. This permits the surgeon to gently tease the epithelium flap out of the way to expose the underlying tissue. An excimer layer reshapes the eye under the flap to correct any refractive errors, after which the flap is replaced over the treated cornea. As with LASIK, the replacement of the flap in LASEK speeds up the natural healing process and serves to minimize discomfort resulting from the procedure.

Although the end result of PRK, LASIK, Customized LASIK, and LASEK is the same - the reduction of refractive errors - the method by which these corrections are made differ. Each procedure has its advantages and disadvantages and is best suited for certain types of patients. Individuals who are considering laser eye surgery to correct their vision and reduce dependency on corrective lenses are urged to contact their ophthalmologist to inquire about available options and learn if they are a strong candidate for one of more of these procedures.Gray Rollins is a featured writer for MyEyeSurgery.com.

Unsure About LASIK Eye Surgery? Epithelial Keratomiluesis Is One Alternaive to LASIK Laser Eye Surgery

Wednesday, May 17th, 2006




Unsure About Lasik Laser Eye Surgery? There Are Alternatives.

It’s true that lasik laser eye surgery is one of the most prevalent types of eye surgery. However, a few people are either not comfortable with, or not suitable for LASIK surgery due to inadequate thickness of the corneal tissue.There are several alternatives toLASIK eye surgery, each possessing certain characteristics that make it more appropriate in a particular situation. The procedures may bedifferent, but the key intent is to correct the vision. The following are a few of the major alternatives toLASIK laser eye surgery.

LASEK (Laser-Assisted Sub-Epithelial Keratomiluesis) is a recent addition to the refractive surgery catalog. As noted above, the density of the corneal tissue is inadequate in some patients, and hence, LASIK is not a possible option for them. In such a scenario, procedures like LASEK or PRK (Photo-Refractive Keratectomy) can be viable alternatives. These procedures produce the same results but require less tissue removal when compared with the LASIK procedure. That is, a thinner flap is cut in the corneal tissue.

Intraocular Lens Implant - In essence, this surgery is the same as cataract extraction with placement of a clear intraocular lens. The natural lens, the one having a refractive error, is extracted and replaced with a clear lens that provides clearer vision. This procedure is especially beneficial if the patient is suffering from hypermetropia (farsightedness) and that too with a high refractive error.

Spectacles or Contact Lenses - Glasses and contact lenses have been a popular choice for many years now. They are an affordable alternative to LASIK surgery. Spectacles or contact lenses are certainly a much safer proposition, since any sort of surgery has a potential for side effects and complications. There can be nothing as simple as wearing spectacles or contact lenses. With an elaborate series of new designs and makes, your spectacles can be strong fashion statement as well.

Don’t hastily jump on a conclusion. It is advised that you carefully examine all the above alternatives prior to going in for a surgery. Do your best to avoid any surgical treatment. If you suffer from a minor refractive error, one that can be easily corrected by wearing glasses or contact lenses, there is no point going in for a LASIK surgery.
