The first step you need to begin this surgery is to have a meeting with oculist or simply called an eye doctor who is an expert in LASIK operation. At the time of meeting the eye doctor, he or she is likely to perform some analysis on your eyes to determine if you are fit for this operation. The price and risks of this surgery may also be revealed to you.

You will be told to quit putting on contact glasses, if you do use any. This is because they are likely to alter the position of your eye and it is not recommended to use it for some weeks before you undergo this surgery. The duration of time differs based on the kind of contacts you should put on. There is a possibility for the doc to tell you to change eyeglasses prior to your first assessment.

You should drive down to the operation point in time. This will enable you to see properly to ride back right away at the end of the surgery. Majority of persons that undergo this surgery consume a downer prior to taking this operation. You will need to be there a bit too soon if you want to have a downer. It will aid to calm you down at the time of the process.

You will need to lie on your back as benumbing drops are directed at your eyes. As the doc removes some flaps out of your cornea, you will encounter the form of vision that is blurry. The doc will tell you to gaze at a particular place for about 1 minute so he will be able to put the laser to your eyes. As soon as the laser has been done, the flap of the cornea will be put back to your eyes.

It will cost you about $3000 for LASIK vision improvement surgery. You should also bear in mind that there are complications with this form of surgery. The satisfaction rate of people who performed this surgery is at 92 to 98%.

What is astigmatism? Astigmatism is a kind of vision disorders (usually blurred vision) caused by distortions in the curved shape of the front surface of the eye (cornea) and/or the curvature of the lens inside the eye. It can also be caused by years of stress and strain on the eyes. The strain on the eyes can weaken the tiny muscles around the eyes. Problems appear when the eyes need to change shape of cornea or lens. An irregular shape of cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.

Astigmatism usually comes together with other vision problems like nearsightedness (myopia) and farsightedness (hyperopia). All of these vision conditions are called refractive errors because they influence how the eyes bend or “refract” light. Now the question is how we can do the astigmatism correction when we have these errors. Below are just a few tips which you can do to heal astigmatism.

You can use a pendulum for astigmatism correction. You just lie on the floor and swing the pendulum over your head. Try to follow and focus on direction where the pendulum moves. This exercise can keep your eyes focused on one object. If you keep doing this exercise, your eyes will have better capability in focusing on a certain object.

When you feel your eyes are tired, you should take a break. Spend a few minutes to relax your eyes. During the break you can have eye exercise by moving your eyes around. You can also look at the yard or green grass outside. Keep your eyes away from your computer monitor if you work with a computer. Relaxation can release the tense of tiny muscles on your eyes. After the relaxation you will recover your vision.

Another treatment for astigmatism is called Orthokeratology (ortho-k). This treatment uses a series of specially designed rigid contact lenses to slowly reshape the curvature of the cornea. What is good about this treatment is that it is painless.

Eye surgery is also another option for treating astigmatism. The surgery usually uses laser. The purpose of the surgery is to reshape the cornea by removing a small part of eye tissue.

Who Can Benefit From LASEK Eye Surgery?

Patients who suffer from refractive errors will be delighted to learn that LASEK eye surgery can once and for all allow them to live life with more freedom and no longer rely on corrective eyewear.

LASEK eye surgery can be used to treat the following refractive errors:

• Short-sightedness (myopia) – This eye condition results from the cornea being slightly rounder and shorter than it should be. Due to this, the light that enters the eye converges just in front of the retina, meaning that suffers experience difficulty when trying to see a clear image at a distance. Through LASEK eye surgery, the shape of the cornea is corrected and the light is made to focus precisely on the retina – meaning that the blurred images at a distance will become a thing of the past, eliminating the effects of short-sightedness!
• Long-sightedness (hyperopia) – Patients who suffer from hyperopia have a cornea that is slightly flatter and shorter than it should be. This results in a blurred image because the light that enters the eye focuses on a point just behind the retina. Most people who suffer from this refractive error rely on glasses on contact lenses, but through LASEK eye surgery, the effects of hyperopia can be permanently corrected. That means no more headaches and straining eyes to get objects – both near and far – into focus.
• Astigmatism – In this case, the cornea is a more conical shape than it should be – this means that light enters at different angles through this cone. This creates two points of focus and ultimately a blurred image. Although this condition is slightly more complex than myopia or hyperopia, using the right technology, virtually all astigmatism symptoms can be treated through LASEK eye surgery.

What Does the LASEK Procedure Involve?

A patient is deemed an appropriate candidate for LASEK eye surgery when they suffer from one of the above mentioned refractive errors and usually because their cornea is not thick enough to withstand LASIK eye surgery. During the LASEK procedure, an ophthalmic surgeon focuses of the preservation of the corneal epithelium. In this way, the procedure differs from both LASIK and as the surgeon does not create a corneal flap or scrape and remove the epithelium.

LASEK treats the epithelium with a diluted alcohol solution which loosens it; the surgeon then rolls the epithelium tissue back and works with a laser to reshape the exposed corneal tissue beneath. The surgeon then simply smoothly rolls back the epithelium cells in their new reshaped position.

What Happens After Laser Eye Surgery?

Recovery time from LASEK eye surgery tends to take slightly longer than that of LASIK, but in the hands of expert surgeons, the visual outcomes are the same. Patients experience vast vision improvement with maximum convenience.

Post-treatment, patients are usually prescribed medicated eye drops which aid the healing process and relieve any temporary discomfort during this time. For about the first week, patients are given a night shield to wear when sleeping, which prevents any accidental rubbing of the eyes. In some cases, patients are fitted with soft contact lenses to give further protection to the healing eyes.

Patients who undergo LASEK eye surgery will find they have a newfound freedom as they no longer have to rely on glasses or the deal with the hassles of contact lenses or spectacles. Due to their vast visual improvement, many patients say that their self-esteem is boosted, along with their confidence!

The London Vision Clinic is leading laser eye surgery clinic in the UK, boasting world-class ophthalmic surgeons who expertly perform LASIK and LASEK eye surgery. If you suffer from a refractive error and are considering LASEK eye surgery, contact one of the Patient Education Consultants at the London Vision Clinic today to set up a screening to determine your suitability for the procedure.

These RK patients do have corneal issues 10 plus years later. Their corneas often display a brownish line in the bottom half indicating iron left behind when the endothelial pump removes fluid from the cornea. In addition, most of these patients are far sighted with astigmatism and their prescription gets stronger later in the day. This makes it difficult to have an accurate eye glass prescription. Weakness of the cornea also increases the risk of corneal rupture when exposed to trauma.

LASIK and PRK do not flatten out the entire width of the cornea thus leaving the endothelial layer intact. This does not affect the pump or the functioning of the physiology of the corneal tissue. Therefore negative corneal changes that are displayed in RK patients should not occur in the LASIK and PRK patients.

According to an article published in the November issue of the Archives of Ophthalmology, there are no long term destructive corneal effects following LASIK and PRK. The study examined 29 myopic LASIK and PRK patients 9 years after the surgery and found them to display no abnormal changes. There was a 5.3% decrease in the endothelial cell density which corresponds to a normal cell decrease in individuals that never had the refractive procedure.

While the study did not examine far sighted post operative patients, they concluded that the results would be similar to the near sighted patients. Whereas post operative RK patients displayed corneal changes after 5 years, the LASIK and PRK patients did not show any signs after 9 years. Further studies must be conducted at longer post op intervals to fully examine the long term effects, but this initial study is very encouraging.

It is true that contacts can let oxygen through, but sometimes they can not. If people wear contacts for very long time, on these lenses will be some wastes that can be barriers for oxygen. So people should replace their contacts often. Still, many people love to sleep in their contacts. This is also a very bad for the health of corneas.

While at night, corneas will expand to some extent. However, contacts will worsen this expansion process which can not be compensated correspondingly. Fortunately, the latest contacts that can let through sufficient oxygen will not worsen the expansion. On the contrary, if the corneas can not get sufficient oxygen, some new tissues will appear on them for more oxygen. Such changes are mainly for some essential needs. However, these tissues will cause some problems on the eyes.

If these tissues are minor and do not grow big, they can be neglected. However, if there are amassing amount of these tissues, corneas will suffer a lot. The results will always be blurriness or even blindness. Luckily, there are some methods that can be used to deal with these problems. One should try not to sleep in their contacts. Of course, one can also choose to wear contacts with perfect oxygen permeability. Nowadays, the manufactures of contacts have noticed that there are some defects in their materials, so they spare no efforts to upgrade their products. The latest ones can now be used to eliminate many complications that often occur in the past.

These contacts can let through almost all oxygen that eyes need. It is true that wastes will be left on the lenses after wearing for very long time. But within certain extend, such waste will not impede the permeability of oxygen. Anyway, people are suggested to follow the advices of their eye doctors in selecting contacts, though there are some new products in the market. The latest lenses can seldom lead to the growth of some tissues in the corneas. However, people should often visit their eye doctors if they find any changes in their eyes, even though they wear some latest lenses.

Wearing rigid gas permeable contacts can help avoid such progression. Some eye doctors now tend to recommend some latest contacts. These lenses are made from very special materials and wearers are less likely to suffer from some in-growth-tissues problems in the corneas than they used to be. The eye doctors have the latest information of these lenses. Nowadays, many famous contacts manufactures are engaged in the research and development of such lenses. Astigmatism and presbyopia can be easily treated with their products. Contacts with perfect gas permeability can promise healthy eyes.

The most general type of laser eye surgery is LASIK, but all types are voted for out by a laser which reshapes the cornea and eliminates some corneal tissue to change the focussing power of the eye.

People must take probable complications into consideration and make an acquainted conclusion about whether to get laser eye surgery.

Major Complications asoociated with Laser Eye Surgery Flap Damage or Loss

Instead of conceiving a hinged flap of tissue on the centered cornea, the whole flap could arrive off. If this were to happen it could be restored after the laser treatment. However, there is a risk that the flap could be impaired or lost.

Distorted Flap

Irregular healing of the corneal flap could conceive a garbled corneal form, producing in a decline of best-corrected vision. It should be documented that whereas difficulties of laser eye surgery are uncommon your surgeon should announce you about them former to treatment

Double Vision

Two images emerge when looking through one eye at a time.

Time Glare

Headlight glare when going by car at night.

Night Myopia

This is a inclination for eyes to become more nearsighted at evening, premier to blurry vision. This can be amended by wearing crystal with minus lenses in the dark

Halos and starbursts

This happens when the student enlarges after the treated locality at nighttime.

Vision Blurring

This is when images emerge blurrier after the refractive surgery than before.

Flap Melt

The flap starts to disintegrate and may need surgical intervention.

Flap Dislocation

This is a status in which the corneal flap is not in correct alignment in the corneal bed. This is treated with surgical intervention.

Flap Wrinkles

A foremost or secondary flap dislocation makes flap wrinkles. This is treated with surgical intervention. This is all about complications associated with Laser Eye Surgery. Hope this will help you a lot. Cheers!

If there is no uncomfortable feeling, the patient could go to the hospital for a counter checking in 4 or 5 days. If the checking result is all right, the wearing time can be lengthened to a whole day. However, it still should be controlled in 14 to 16 hours a day, no wearing during sleeping time.

When touching the contact lens, patients should at first cleaned their hands with soaps and remember trimming the nails in time to avoid harming the lens or the cornea. It’s easy for contact lens to get viruses and epiphyte on the surface and they should be disinfected every day. The lens should be put in storing cases filled with preserving fluid and remember to replace the fluid every day, plus cleaning the cases regularly.

Protein in tears may be attached to the lens and the patients should use certain dose to get rid of it at least once a week. Female users should pay attention that the lens could be polluted by cosmetics. Besides, before or during wearing the lens, pay attention not to use the eye drops because some eye drops may color the lens or the preservative may contract and hurt the cornea.
 
The tending work and timely visit to hospital are quite important for wearing contact lens. Prompt and regular countercheck helps to know the health status of eyes and reactions to wearing contact lens. Thus it can help to wear more safely. For that the contact lens will touch the cornea closely, and may result in exfoliation of corneal epithelium, macropapillary conjunctivitis and other diseases.

Besides, the patients can judge whether they have properly worn the contact lens by seeing if they can see clearly, feeling comfortably and the eyes are not red after having worn the lens.

One of my roommates is deeply fond of wearing the contact lenses. One night when she took off her contact lenses, she found that her eye red and swollen. At first we all thought that it was because she was too busy at that time. She needed to drop some eye drops and have a good sleep. About thirty minutes later she got up and said that her eyes were painful.

It should be that. Before if our eyes were sick, the eye drops were vey helpful. It was strange so we decided to see the doctor. After the examination, the doctor said that my roommate’s eye corneas had already ulcer. When we asked whether it was serious, the doctor was just shaking his head. We knew that it was serious. Then the doctor said that my roommate’s vision would drop badly and even she was cured, there would be some white spots in her eyes. The doctor’s remarks made me fear.

Like my roommate, I also wore the contact glasses. So I should not wear them at all. I said this to the doctor. The doctor said that it was OK if we did not wear the contact lenses for long time. What was the worse is that the contact lenses would absorb our tear and the collagens which can multiplies the germ and then cause the cornea dropsy. It sounded that the contact lenses were too dangerous.

When we asked why the contact lenses were so harmful to our eyes, the doctor said that our eyes, like our skins, need breathing. When we wore the contact lenses, our eyes could not breathe, so they were lacking in the oxygen.

The danger of the contact lenses is potential. At the most time we can not realize them clearly so we should not wear them for a long time and we should examine our eyes frequently.
