We all want to have perfect eye sight for the rest of our lives but for most people this is simply not going to happen. So many people will go through their entire lives not really having full vision and having to wear glasses and contact lenses every day to enhance their vision. Many others will have even worse vision or may not be able to see at all. There are lots of eyesight problems and the solutions to them will range depending on their severity.
Healthy diet to regain vision clarity
We all know that prevention is better than cure and therefore the best way to avoid any sort of eyesight problem later on in life will be to actually make sure that you use certain preventative measures. One of the best of these will be to have a good healthy diet. By maintaining a good diet you will see health benefits across the board and not only in your eyesight. Eating things that are high in vitamin A are excellent.
In addition to this eating things like spinach and carrots that have a high level of antioxidants have also been seen to be beneficial in helping people improve and maintain their eyesight.
Eye exercises to strengthen the eye muscles
Many people are faced with various eyesight problems and the solutions are actually simple if they know how to do in correct ways. Eye experts often suggest their patients to do a lot of exercises. These can be done both through regular exercise of the body and also specific eye exercises that you can use. If you do cardio exercise on a regular basis you will keep the blood flowing round the body more readily and this is excellent for all functions.
There are lots of ways in which you can exercise your eyes. One simple trick is simply to hold out your thumb in front of you and then follow it in a figure of eight movement. Done several times a day for several minutes, this will help to improve your vision.
These are only a few simple ways to naturally improve your vision. Without having expensive eye surgery, you can find many other ways to help improve your eyesight without depending your glasses and contacts.

Astigmatism.
An astigmatism is a vision disorder in which a persons vision becomes blurred. This occurs when the surface of the cornea becomes damaged. This can happen from straining eyes too often is simply from old age. This condition is quite common and can be harmless in slight cases; however, it can be quite debilitating for some. While laser surgery is an option, many are choosing to try natural astigmatism correction methods first.
Rest your eyes
To keep astigmatism from getting worse over time, you should take care to rest your eyes often. When you find that your eyes are feeling tired and strained, take a few minutes to do something different and try to rest your eyes. Especially those who work on computers all day have this to deal with.
Eye exercises Practice exercising your eyes to improve the muscle tone and reduce the astigmatism. These exercises only take a little of your time and will save you hundreds of dollars in medical bills. Many are skeptical, but if you will commit to these exercises, you will see some drastic changes in your eyesight.
One method of natural astigmatism correction involves swinging a pendulum or other object over your head. Practice holding your head still while following the object with your eyes. Also, doing things that involve hand to eye coordination will strengthen the eye muscles and sharpen your vision as well.
Changing focus
You can also practice alternating near and far away reading. This eye tracking and fixation practice helps to improve the eyes flexibility and will over time bring relief to those suffering from eye strain and other eye issues.
Special contact lenses There is also a new method of treatment involving special contact lenses that are designed to gradually reshape the cornea. This is a treatment that has been proven quite effective and is painless, though it has not been widely used. This process is called Orthokeratology.
Learn and practice other natural astigmatism correction methods so that you can use your eyes in a way that allows for balanced and effortless seeing even without the help of eye glasses or contacts.

Canaloplasty.
Our eyesight is precious to us. Every day we rely on seeing the very things we take for granted.
Our language is littered with expressions like; "Look over there", "Did you see that", "In our field of vision" and similar expressions related to seeing.
The rise in eye pressure or intraocular eye pressure (IOP), puts pressure on the optic nerve at the back of the eye. This pressure on the optic nerve increases the likelihood of permanent damage to this vital nerve. When this occurs our peripheral vision is reduced - permanently. We see less and less around the edge of our area of vision, ultimately leading to a condition called tunnel vision and in severe cases blindness. It is because of this gradual decline in our vision that glaucoma is often referred to as the silent thief.
Traditionally, glaucoma has been treated with medications usually, in the form of eye drops. Do you forget doses? Do you find applying eye drops fiddly? Frustrated, with the on-going cost of these medications? With the advances in micro surgery, there are now viable surgical alternatives, which may reduce the need for eye drops and in many cases eliminate the need for eye drops altogether.
The usual method of surgery to lower eye pressure is trabeculectomy. This creates a hole in the sclera to let the aqueous fluid drain into the outer cyst or bleb. Trabeculectomy is still the surgical standard, but there are risks of complications such as infection, leakage, and irritation.
Another surgical option is Canaloplasty. This utilises a very small tube placed in the Canal of Schlemm (a small channel around the iris for draining eye-fluid or aqueous humor) to enlarge the drainage canal, allowing the fluid to drain more freely, thereby relieving pressure inside the eye. This has been a successful method of reducing the eye pressure causing glaucoma.
Canaloplasty is a valuable minimally invasive surgical option in patients with open angle glaucoma, particularly in patients at high risk from infection or bleeding.
Canaloplasty is a safe and new procedure taking advantage of the normal drainage system of the eye to safely treat increased pressure in people with glaucoma. A tiny incision is made to gain access to the eye. A microcatheter is inserted into the canal to enlarge the main drainage channel by injecting a sterile gel-like material called viscoelastic.
After the drainage channel is made larger, the microcatheter is removed and a suture is placed within the canal and tightened to make sure that it stays open. By opening the canal, it will drain correctly, and the pressure inside the eye will be relieved.
Some points to remember about Canaloplasty
* Can safely lower eye pressure (IOP) by up to 40%* Reduces or eliminates the need for eye-drops
Only your doctor can decide if canaloplasty is right for you - talk to your doctor.
* Less risk of complications after surgery
* Glaucoma now under control.Imagine waking up in the morning and not having to puts drops into your eyes or like me having to remember to apply eye drops three times a day. Memory is such a fickle thing with age!

Eye Laser Treatment - Repair Damaged Vision
Eye laser treatment goes by several different names. It is known as LASIK (laser-assisted in situ keratomiluesis), LTK (laser-thermokeratoplasty), keratectomy or PRK (photorefractive keratotomy). Using these procedures, a physician can correct a number of vision defects.
Astigmatism is a defect that causes vision to be significantly blurred because of decreased visual acuity. This is very difficult to correct using the traditional lenses found in glasses or contacts, but it can be corrected by eye laser treatment. A procedure such as LASIK can help smooth the cornea, creating a spherical shape, which improves vision.
With myopia, or nearsightedness, the cornea is too steep. This condition can cause eyestrain and headaches because the person is often squinting to see objects in the distance. Eye laser treatment can help correct this refractive error by flattening the cornea. On the other hand, hyperopia, or farsightedness, means that a person can clearly see objects at a distance, but will oftentimes have trouble deciphering letters in a book they are reading. Surgical procedures using lasers can alter the shape of the cornea, thereby increasing the person's ability to see objects that are close up such as books and magazines.
Glaucoma is a loss of vision from optic nerve damage. Intraocular pressure is thought to play a part in this damage. Eye laser treatment can help by creating scars in the eye's drainage system, which can reduce pressure.
Diabetic retinopathy can lead to PDR (proliferative diabetic retinopathy) which can cause loss of vision, neovascular glaucoma and retinal detachment. PDR occurs in patients with diabetes. This can be treated with a form of surgery called PRP (pan retinal photocoagulation).
These procedures are done while the patient is awake. The patient is given some medication to help calm and relax them. Drops are placed to help numb the area. The patient then lies back in a chair and a lid speculum is placed to hold the eyelid open. During the procedure, the patient may experience slight pressure and discomfort, but it should not be painful. The exact procedure the physician uses will depend on the type and degree of vision defect being treated. When this is finished, there will be a shield placed over the eyelid to prevent injury.
After eye laser treatment, there may be some itching, burning or irritation. The eyes may water up, but it is very important not you rub them. There may also be some light sensitivity and the eyes may appear bloodshot. A patient may not wear eye makeup for at least two weeks. No contact sports should be performed for at least four weeks, and during this time, an eye-shield should also be worn at night. It will be 8 weeks before the patient is allowed to swim or use a hot tub. If any severe pain is felt, the patient's physician should be immediately

Lasik Vision Surgery.
Refractive surgeries are cosmetic, elective procedures performed to reshape corneal tissue and correct refractive errors so that eyeglasses or contact lenses are no longer needed. Current procedures include radial keratotomy, photorefractive keratectomy (PFK), and Lasik vision surgery.
Among the different refractive surgeries, Lasik vision surgery is considered as one of the most convenient and has shorter recovery time compared to photorefractive keratectomy or PRK. Statistics show that nearly 99% of patients who used to wear eyeglasses can do without them after undergoing Lasik vision surgery and the visual acuity rates more than 99% as well.
Lasik vision surgery combines delicate surgical procedures and laser treatment. A flap is surgically created and lifted to one side. A laser is then applied to the cornea to reshape it. This type of refractive surgery alters the major optical function of the eye and thereby carries certain surgical risks. The patient must fully understand benefits, potential risks and complications, common side effects, and limitations of the procedure.
Lasik vision surgery does not alter the normal aging process of the eye. If the reason for the procedure is occupational vision requirements, the results must satisfy both the patient and the employer. Precise visual outcome cannot be guaranteed with certainty. Typically, patients must be at least 18 years of age.
The corneal structure must be normal and refractive error stable. Patients are required to discontinue using contact lenses for a period before the procedure, preferably 2 to 3 weeks for soft lenses and 4 weeks for hard lenses. Patients with conditions that are likely to adversely affect corneal wound healing, such as corticosteroid use, immunosuppression, are not good candidates for the procedure. Any superficial eye disease must be diagnosed and fully treated before a refractive procedure.

Cataract Surgery Risks and Complications You Should Know
Cataract surgery risks and complications are rare and its successful results are extremely high. Nevertheless, as any other medical operations, there are always risks and complications you should be aware of. The risk of blindness is extremely low and may happen if there is infection or bleeding in the eye.
The following are common risks of cataract surgery that usually occur after the surgery itself.
Retinal detachment is a condition when fluid leak through a tear in the retina. This causes the retina detached from the back of the eye. Patients who have retinal detachment after surgery, will see flashes of light or dark spots. It is necessary to have an immediate examination if this condition occur, though these symptoms generally happen after cataract surgery.
Posterior Capsule Opacity (PCO), is a condition where your vision is cloudy or blurry after cataract surgery. A PCO is a hazy membrane (capsule) behind the artificial intraocular lens (IOL) that was implanted during your cataract surgery to replace your natural lens. A YAG laser is generally used to treat posterior capsule opacity and it is done in simple steps: dilating eye drops, hazy posterior capsule removal and anti-inflammatory eye drops. The entire procedure will take only a few minutes without causing discomfort and pain.
Another cataract risk surgery is mal-positioned or dislocated intraocular lenses that causes double vision and if the intraocular lens becomes very badly dislocated, your visual sharpness will decrease substantially. If you have this condition it is advisable to have an immediate action from your doctor and it is possible that you might follow a second procedure.
Cystoid macula edema or decreased vision, is a condition caused to swelling in the layer of nerve cells that covers the retina. The macula is the part of the retina that responds to light in the central part of the visual field. Even in cataract surgery that has no risk and complication, blood vessels in the retina can swell causing decreased vision. Contact your doctor immediately if this condition occurs. An anti-inflammatory eye drops or injections of steroids to the back of the eye can treat this problem
Dislocated lens material is a rare occurrence where fragments of the lens have fallen into the cavity behind the membrane that surrounds the lens. Virectomy procedure can remove particles and reduce the swelling.
Endophthalmitus or infection inside the eye may occur after surgery that cause pain, swelling, redness and sensitivity to light. Usually antibiotic eye drops are administered to treat this condition and infection will heal eventually.
Choroidal hemorrhage is when the web of fine blood vessels (choroids) bleed during surgery. Choroidal hemorrhage usually occurs in patients who have high blood pressure or glaucoma. When a hemorrhage confined to a small area patients may only have small risk of visual loss but if the hemorrhage is severe, significant visual loss may occur.
Even cataract surgery risks and complications are rare thanks to the modern medical research and innovations, you should be aware of any possibility laying ahead.
Remember that your eyes are very precious and you have many chances and opportunity to have better vision. What could be more important than having a clear eyesight and enjoy a carefree life?

LASIK.
LASIK is a abbreviation for laser assisted in situ keratomileusis, the favorite eye procedure known to result in finer sight for many individuals. Millions of individuals have been assisted by the LASIK and also no more have to depend upon eye glasses and or the contact lens. Many individuals who experience getting a LASIK surgical process receives the finer vision, due to the advancement of technology nowadays. But, in spite of high percentage in success there can be problems linked to a surgical procedure of the LASIK eye surgical procedure. Before the LASIK procedure perform research, and ask what this surgical process entails and also what the negative result may be.
LASIK surgery changes the corneal shape, when you undergo the LASIK eye surgical process, this tissue layer arching to the pupil and the iris or a eye's colored part. When the procedure is finished, the cornea can bend those beams of light thus focusing exactly to the retina instead of beyond or in front of the point of the retina.
Diagnostic Overview
An improvement over PRK, particularly for correcting high or severe myopia (nearsightedness), a refractive error in which the focus of light rays from a distant object is anterior to the retina, Laser-assisted In Situ Keratomileusis, involves flattening the anterior curvature of the cornea by removing a ìstromal lamellaî or layer. The surgeon creates a corneal flap with a microkeratome, which is an automatic corneal shaper similar to a carpenter's plane. The surgeon retracts a flap of corneal tissue less than one-third of the thickness of a human hair to access the corneal stroma and then uses the excalculated measurements. The corneal flap, a naturally adhering bandage, is rolled back and repositioned.

LASIK also appears to be an effective, predictable, stable, and safe procedure for correcting residual myopia after cataract surgery. This type of eye surgery causes less postoperative discomfort, has fewer side effects, and is safer than PRK. The patient has no corneal haze and requires less postoperative care. However, the cornea has been invaded at a deeper level, and any complications are more significant than those that can occur with PRK.
Complications
1. Ablation-related complications
Ablation complications include an elevated area within the corneal treatment ablation zone or central island. Signs and symptoms of this complication include ghosting, blurred vision, halo formation around lights, decreased visual activity, and contrast sensitivity in low light.
2. Diffuse Lamellar Keratitis
As refractive surgery increases and is performed more often, the vision-threatening complication known as diffuse lamellar keratitis (DLK) is reported more often.
DLK is a peculiar, noninfectious, inflammatory reaction in the lamellar interface after Lasik vision surgery. DLK is characterized by a white, granular, diffuse, culture-negative lamellar keratitis occurring in the first week after surgery. Studies suggest that, because no single agent appears to be solely the cause of DLK, the cause is multi-factorial.
This is a real great choice when the eyes have the nearsighted fault or myopia, a farsighted vision or what is named astigmatism. The nearsighted person features an eyeball may be somewhat longer then the normal or it might be curving in sharply, it would cause the shaft of light in concentrating on a retina and the sight is fuzzy. While a farsighted fault is opposite, in some way: there might be the shorter than the normal eyeballs, or the cornea could be very flat focusing the light behind instead of on the retina, so it causes a near vision and hazy on distance. When the cornea is curving or if it flattens irregularly, it can cause astigmatism. It disrupts the focus of the visual acuity of the near also as the distant eye vision.
To cut a cornea or, often called as keratotomy, are being used to a situation when the cornea is deformed that could destruct the optic refraction. When you get the poor refraction, you'll have a very poor sight. The LASIK surgical procedure gives a improved design to the cornea thus improving your vision. Normally there are at least 3 procedural techniques that was included to the family of corneal incisions: If you experience astigmatism, the process identified as astigmatic keratotomy could be used. The process of LASIK is where the surgeon incise then next is to smooth those bulges in the corneal portion of a eye permitting a greater eyesight. The myopic defect on the patient with a nearsighted vision can be cured by the surgical operation LASIK known as keratotomy. That LASIK technique, by the routine of surrounding that cornea with fault then made the arrangement outward by incision resulting to the flat cornea. A treatment addressed as an hexagonal keratotomy is being utilized for rectifying farsighted vision, there could be some sides that might be affected thus causing the LASIK surgeons on rejecting this process.
The positive effects of the lasik surgery might be dependent to a particular assessment to the eyes before the LASIK operation. The vision is so important, and lasik surgery is a special way to improve it.
