The Eyes Have It. They Are More Complex Than Any Computer In The World

The eye is made up of so many parts. Like a camera, what we see from the outside is only a simple picture to what lies beneath. The overall function and design of the eye is much more than just a white ping-pong sized ball with a colourful space and a little black dot. Your eye is the window to the world. It takes thousands of 'calculations' so to speak. What you see is only a small part of the overall picture. The following is a summary of each part and its function.

Part Description Function

Eye socket Hollow space/opening Holds and Supports the function of the eyeball itself

Eyelid Skin over eyeball This skin through muscular automatic and voluntarily movements. It acts in this capacity to help keep the eyeball moist and to keep it clean and free from debris.

Eyelashes Tiny hairs framing at the end of the eyelid. The lashes although decorative are there for much more than holding mascara. Lashes work to catch dirt and minimized it's entrance to the eyeball.

Eyeball Ping-pong sized white part of the eye. The white part of the eye is made up of a tough material called sclera. It covers a huge part of the outer covering for the eye. The eye has noticeable tiny pink threads, (Blood Vessels) which deliver blood to the sclera.

Cornea Clear/Transparent dome. This dome sits in front of the coloured part of the eye. It help the eye focus as light passes through.

The Iris The Coloured Part. Controls how much light goes through the pupil

The Pupil The Little Black Dot Set in the center of the eye, the pupil is actually an opening into the inner parts, the size of this black dot is dependent on the amount of lights it's exposed to.
When the dot is smaller, it's due to brighter light, thereby minimizing the amount of light that enters. When it's larger, this is due to a darker area, in opening, it allows more light in, so you can see a little better in the dark.

Anterior Chamber Not visible. The space between the cornea and the iris. The transparent fluid is there to nourish they eye.

Retina Not visible. Processes what the eye sees. It receives the signals or information which is sent to the brain for understanding.
Your retina is at the far back part of the eye that takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing.
It uses cells called rods and cones to process light. In all there are about 120 million rods and 7 million cones per eye.

Lens Not visible. Like a camera, the lens processes and captures the image. It is held by fibers which are attached to muscles called ciliary muscles. It actually changes the size and shape of the lens.

Vitreous Body Not visible. This sits behind the lens, and forms two thirds of the eye's volume and gives the eye its shape. It's filled with a clear, jelly-like material called the vitreous humor.
Rods Not visible Works the processing of black, white, and shades of gray.

Cones Not visible. Work to process colour. They only see colours. They are most sensitive to one of three colours; red, green, or blue. Together they are able to differ what they see to form millions of other colours. Those without functioning cones experience colour blindness.

Optic Nerve Not visible. Acts as the messenger in the back part of your eye. It carries the information it sees to the brain for understanding.

Lachrymal Glands Tears. These glands produce tears for flushing foreign bodies from the eyes. This fluid is regulated by blinking.
Your eyes do so much; protect them and SEE how great they really are!!

Implantable Contact Lenses Are An Excellent Alternative to LASIK Eye Surgery



Implantable Contact Lenses Are An Excellent Alternative to LASIK Eye Surgery

Not everybody is an acceptable prospect for LASIK eye surgery There is however an alternative to lasik surgery.

A common alternative to LASIK surgery are Implantable Contact Lenses, also occasionally referred to as a permanent contact lens or ICl. An ICL is a soft lens that's affixed to the eye for correcting nearsightedness. An Implanted Contact Lens is meant to be lasting, but it could be replaced if changes are called for in the future. Contrary to  LASIK eye surgery, the ICL operation is totally reversible.

In that respect there are definite advantages to ICL over LASIK. For instance, with LASIK eye surgery, permanent alterations are made to your eye and those alterations are something you will have to live with. If everything went well with the LASIK procedure then clearly there is no issue, however occasionally it does not go as hoped and as such you're stuck with it. In complete contrast, Implantable Contact Lenses may removedt at any time if rectifications are required.

If you have previously worn contact lenses, you already live with  the bothers of normal contacts - cleaning, soaking, removing and replacing, etc. But with implantable contact lenses, all those annoying tasks immediately disappear. The implants are lasting and ought never need any tending unless your vision changes as you age. Implantable contact lenses offer the same vision improvements as normal temporary contact lenses, only they call for none of the attention and upkeep of standard contact lenses.

The ICL routine is generally executed on an outpatient basis and you will feel little or no pain. A gentle sedative is dispensed to provide a calming effect and a 1/8 inch surgical incision is created for insertion of the lens. When inserted, the lens is properly positioned. In virtually all cases, sutures are not needed to close the incision point. If you are getting the operation performed on both eyes, they will both be accomplished in a single session. The whole process is normally accomplished within about 30 minutes.

Upon completion of the ICL procedure, you will be directed to a 'post-op' area for recovery. When staff members ascertain that you're stable, you will be sent off home to unwind for the rest of the day. You will need to come back the following day for a follow-up exam, just to make certain that everything is alright.

On that point may be some mild haziness upon completion of the implantation, but this typically clears itself within a brief time period. Most patients experience fast improvements in vision, with approximately 90% of normal vision restored within the first 24 hours. Usually, your vision on the second day will be good decent to allow you to drive yourself to the examination.

The primary issue of worry with implantable contact lenses is the risk of infection. Once detected it will be sorted out, so it is important to keep in touch with your medical team.

Implantable contact lenses are a sensible alternative to LASIK eye surgery for patients who have trouble with distance vision. Notwithstanding this , ICL does not help you if you require reading glasses.

Are There Risks Associated With LASIK Eye Surgery

Are There Risks Associated With LASIK Eye Surgery

Refractive surgery (LASIK) often produces amazing results, however, as with any medical procedure, there are risks involved. If you're considering LASIK, it's important that you are aware of the limitations and possible complications that may arise.

According to FDA reports, nearly 100% of LASIK patients have good results and no complications, but you need to be aware that there are things that can and do go wrong. Some problems include double or triple vision, light distortion so severe that patients can't drive at night, or eyes so dry that they have to wear goggles when going outside.

Some patients experience infections, inflammation of the eye, redness, blurriness or eye irritation. In many cases, LASIK eye surgery can eliminate your need for corrective lenses, but that's not always the result. Sometimes, LASIK will drastically reduce your dependence on corrective lenses, but you may still require corrective lenses for some activities, such as reading. It's best to think of LASIK as reducing your dependency upon corrective lenses - not necessarily as eliminating your need for them.

Diffuse lamellar keratitis is a post operative LASIK risk that happens when a foreign substance, such as a hair or speck of dirt gets trapped behind the corneal flap. If this happens to you, you may experience pain, light sensitivity, blurred vision, along with the sensation that something is trapped in your eye. Rubbing will only intensify the problem and may lead to further complications, such as infection or tearing or dislodging of the corneal flap. Diffuse lamellar keratitis usually occurs as the result of the patient not exercising proper precautions during the healing period after LASIK eye surgery.

One of the most common complications of LASIK eye surgery is a slipped flap. The flap that was created during the LASIK procedure may become detached from the rest of the cornea. Most doctors recommend that you go home and sleep for several hours after completing the LASIK procedure in order to allow the cornea to start its healing process. That's good advice and can substantially reduce your chances of experiencing a slipped flap.

Even without LASIK eye surgery, it's expected that everyone's eyes will change slightly with the passage of time - it's just a natural part of life. After LASIK, your eyes will still follow their natural course of changing with time, so LASIK shouldn't necessarily be considered a permanent solution. For most people however, their vision will not change enough to require any additional treatments, especially when the original procedure was done to correct for poor distant vision.

The information provided here is not intended to scare you away from LASIK eye surgery, since it has been a blessing to a great many people. For many who have chosen LASIK, it has meant that they are no longer dependent on corrective lenses in order to have good vision. It's highly recommended that you talk with your doctor about LASIK and how any possible risks or side effects relate to your own personal circumstances.

What Not To Do After LASIK Eye Surgery

What Not To Do  After LASIK Eye Surgery

LASIK eye surgery is probably the safest, quickest and easiest way to improve your vision. The healing process happens quickly and for most patients, the process is uneventful. However, in spite of all the cards being stacked in your favor, it is important that you follow the recovery procedure your doctor has outlined for you in order to insure a speedy recovery without any complications.

First and foremost, you'll need to apply the medications prescribed by your doctor according to the established schedule. In most cases, you'll have a steroid based medication that you'll apply quite frequently during the first four hours after LASIK eye surgery. Also, you may have antibiotic eye drops that will help prevent any infection. Be sure to adhere to the schedule with these medications, especially during the first four hours.

After the first four hours, you'll still use these same medications, but the frequency will be reduced to one every six hours.

You should also have a supply of artificial tears to provide lubrication to your eye. Use these drops according to the established schedule and also at anytime your eyes feel dry. Keeping your eyes moist greatly enhances the healing process, so don't skimp on the artificial tears.

As you start to get back into your normal daily activities, there are certain things you'll need to avoid -

- Don't get involved in any activities that could result in an object coming into contact with your eyes.
- When you shower, don't allow the water stream to hit your eyes.
- Don't get soap or shampoo in your eyes.
- Don't get dust or pet hair in your eyes.
- Don't rub your eyes.
- Don't go out in bright sunlight without sun glasses.
- Don't let your eyes get too dry - use the artificial tears as often as needed.
- Don't rub your eyes while you're sleeping - a special mask, provided by your doctor will protect your eyes while sleeping.

It is absolutely imperative that you faithfully follow your doctor's schedule for medications, especially during the first week after your procedure. You've probably been given a steroid based medication to promote quick healing, so be sure to use it. Also, you may have been prescribed antibiotic eye drops to prevent an infection, so be sure to use them as recommended.

Your eyes are important and you'll want to protect them thru the healing process. Be absolutely sure to follow your doctor's instructions and you should have a quick, successful recovery!

LASIK Monocular Vision Correction

LASIK Monocular Vision Correction

For the last several years, doctors have been hesitant to recommend LASIK eye surgery for patients who were farsighted.

Such patients could see clearly at a distance, but had trouble focusing on close up objects. This is a common problem for many people as they age and usually starts showing symptoms in the early to late 40s. The first sign of becoming farsighted is that these people have to hold reading material farther and farther away in order to be able to focus clearly. Eventually, they find that their arms are no longer lengthy enough to achieve proper focus.

LASIK eye surgery can resolve the problem of being farsighted, but at the expense of losing distance focusing. A typical farsighted person can see distant objects with no problem, but while LASIK surgery can solve the close focusing problem, the distance focusing is sacrificed in the process. Most people would consider this as just trading one problem for another.

However, research has shown that there is a way that LASIK eye surgery can help patients that suffer from farsightedness. It seems that the brain possesses powerful capabilities when processing images. The LASIK solution for farsightedness is to perform the procedure on one eye only, hence the name 'monocular'.

An eye exam is used to determine which eye is best suited for distance viewing and that eye remains unaltered. The other eye undergoes the LASIK procedure and is then optimized for close object focusing. When the patient views an object, whether it's near or far away, the brain accepts images from both eyes and merges the images thru complex processing. In essence, one eye focuses on far away objects and the other eye focuses on close up objects. The brain uses both images and the end result is that patients can now see close up and far away - problem solved!

If you're at the age where you've just begun to notice your farsightedness, it may be best to wait a couple of years before having the LASIK eye surgery. The reasoning is that during the initial onset of farsightedness, your eyes tend to change frequently, so if you have the procedure done too early, your changing eyes could negate the results in a year or two, so you may need to have the procedure repeated. If you wait until your eyes stabilize, or at least the changing process slows, you're likely to realize longer lasting results.

Many LASIK surgery doctors have been offering an option when you elect to have the procedure - for a fairly small extra fee, they'll provide you with lifetime repeat procedures for free if they're ever needed. This way, if your eyes do change as you age, you can have the LASIK procedure repeated at no additional cost. This can be a wise investment if you're in the 40 to 50 age group.

If you have the monocular vision correction procedure, you'll find that it does take a little getting used to. After all, your eyes have been providing very similar signals to your brain for a long time. Now that each eye focuses differently, your brain has to adapt and process the different images into a single view.
