Laser Eye surgery is more and more popular, which is a methods to solve vision problems, such as nearsightedness, farsightedness, or astigmatism. With the development of laser eye surgery technology, the risk of getting side effects has reduced greatly for the past years. Although some people who are promoting it will tell you it is completely safe now. Actually it isn’t true even when the most advanced technologies are used during the laser eye surgery. And there have already been many reports about the laser surgery complications that has happened all oven the world.
There are many kinds of complications as a result of laser eye surgery. So if you are one of the patients who is considering undergoing laser eye surgery soon, it is necessary for you to know the possible eye problems that can occur after the procedure.
Following are three complications. Dry Eyes is probable the most common problems after laser eye surgery, which means your eyes lose the ability to keep themselves moist. Though it is not a serious problem, dry eyes may also cause severe discomfort to the patient, such as irritation or eye pain. When dry eyes occurred, external lubrication is usually needed.
Many people may experience double vision after they undergo laser surgery. And it is dangerous for those patients to drive if they are suffering from this eye problem caused by laser eye surgery, because they may suffer oversensitivity to light, and hard to see at night.
Since laser is so powerful that any mistakes may cause severe injury to the eyes. The worst condition is completely blind, which is irreversible. Although the possibility of permanently loss you vision is really small, remember it CAN happen. So if you are considering having laser eye surgery, you’d better know more about it.

If you dream of freedom from glasses or contact lenses laser vision correction may be the solution for you. LASIK is the most well-known vision correction procedure, but there are several other types of laser vision correction. By reshaping your cornea, your ophthalmologist can correct nearsightedness, farsightedness, and astigmatism, giving you clear vision without the hassle of corrective lenses.
Refractive Error
Nearsightedness (myopia), farsightedness (hyperopia), and astigmatism are all forms of refractive error. Your cornea bends, or refracts, light to focus on the retina. When your cornea is misshapen the light does not focus properly. Refractive surgery reshapes your cornea, correcting how the light is bent and therefore correcting the focus of the light on the retina.
Types of Laser Vision Correction
You have probably heard of LASIK, but might not be aware that there are two types of LASIK, traditional and custom, and that there are several other forms of laser vision correction including:
- Epi-LASIK
- iLASIK
- LASEK
- InterLase
- PRK
All are performed using an excimer laser. The technique is different for each type of laser surgery, making laser vision correction possible for people who are not good candidates for LASIK.
The Precision of Today’s Laser Vision Correction
Refractive surgery is not new, but it is being constantly improved. Traditional LASIK has been used to safely and effectively correct vision for over twenty years. Custom LASIK is far more precise, and can give you even clearer vision.
In custom LASIK, Wavefront technology is used to map your eyes and guide the laser. Wavefront is also used to guide other types of laser vision correction. Wavefront diagnosis helps your ophthalmologist determine which type of laser surgery is right for you, and can detect high order aberrations that can be made worse by LASIK surgery.
Improving Your Vision and Your Life
Laser vision correction can mean freedom from corrective lenses for many patients. Those with very poor vision can achieve better corrected vision. Improving your eyesight can open up opportunities that you never had before. It may simply make things like swimming and other hobbies easier and more fun. For some, it can make essential activities, such as driving, possible. Getting rid of your glasses or contacts means waking up each morning with clear vision and never again having to worry about losing or damaging your lenses.

Selecting a pair of children’s eyeglasses always requires more time and skills. Some parents are quite confused by the various types of children’s eyeglasses. Actually, there are many different kinds of spectacle frames that are specially designed for those kids. With this wider selection, parents are more likely to get confused that which frame is exactly suitable for their kids. One requirement is clear that a kid should feel comfortable with his or her glasses.
For those kids, eyeglasses are needed because they have visual problems such as nearsightedness or farsightedness. Without proper eyeglasses, they can only see distant objects or things close up. And the severity of a specific visual problem determines how long a kid should wear the eyeglasses. With slight refractive errors, some children only need to wear their glasses part time, such as studying. Some others may have to wear their eyeglasses all the time. They remove eyeglasses only before going to sleep. In most cases, the doctor suggests the wearing period for a specific kid. But the selection of eyeglass frame needs opinions from the parent, child and the optician.
Safety should be given the top priority while choosing eyeglasses for children. Children’s eyeglasses always deserve the best fit, which is neither too tight nor too loose. In addition, children always need a pair of eyeglasses with an arm that is long enough to go behind the ear. Spring hinges are particularly necessary for children, because they can protect glasses from easy breakdown.
For children’s eyeglasses, enough space between the lenses and the eyes should be set aside, in order to allow the air to come through smoothly. Eyeglasses for kids can be made from both plastic and wire. In addition, most male kids prefer glasses with a double bridge while a girl always opt for the ones with a single bridge. Another interesting phenomenon is that some children like eyeglasses equipped with styles that are originally designed for their parents.
In the early years of the development of children’s eyeglasses, plastics were most widely used because they are more durable. However, a lot of metal frames are also available for the majority of children. For instance, nickel alloys are commonly used now. In some cases, more than one pair of eyeglasses is needed by a kid.

Eyesight is usually described in terms of visual acuity. When someone says “20/20 vision” we normally think of perfect vision. However, acuity is just one aspect of how well you actually see. Vision quality can be just as important in your day-to-day life. Higher order aberrations can diminish vision quality without affecting your score on the eye chart. Wavefront diagnosis detects these tiny imperfections in your eye prior to laser vision correction so that you can have precise correction and to avoid making them worse.
High Order Aberrations and Vision Quality
High order aberrations can cause problems with your vision including:
- Glare
- Shadows
- Poor contrast sensitivity
- Poor night vision
- Halos
- Double vision
These problems affect the quality of your vision, but do not always affect your visual acuity. Visual acuity is what is measured on the eye chart and is typically diminished by lower order aberrations – myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
While visual acuity is certainly important and can affect your eligibility for some professions and ability to hold a driver’s license, the importance of vision quality and the impact it has on your quality of life should not be overlooked.
Wavefront Technology
Wavefront technology is not new, but it has only been utilized in ophthalmology since the 1990’s. It was developed for astronomers to use in adjusting their telescopes to get the clearest image.
In ophthalmology Wavefront technology is used for diagnosis and to guide the laser during refractive surgery.
Wavefront Diagnosis and Why It is Important
During the diagnostic phase of your treatment Wavefront is used to create a 3-D map of your eyes. It detects the tiny high order aberrations that other tests cannot pick up. Light is passed into your eye, passes through the parts of your eye and reflects back out. Any differences in the pattern of the light as it passes in and when comes back out are aberrations.
High order aberrations can be made worse by LASIK surgery. Wavefront diagnosis reveals these aberrations to your ophthalmologist so he can correct them, work around them in a way that will not exacerbate any existing problems with your vision quality, or when appropriate advise against the surgery.
Wavefront diagnosis can help your eye surgeon determine whether or not LASIK or another type of laser vision correction can improve your vision. If you do not have any higher order aberrations, you may choose traditional LASIK. If you do have them, you need custom LASIK which will use the map created during your diagnosis to guide the surgery, producing very precise results.
Even if you plan to have traditional LASIK surgery, you need the Wavefront diagnosis to determine if it is safe for you.
If you have vision problems that include halos, starburst, double vision, or other problems with vision quality, please visit Eyes.com to learn more about how you can improve your eyesight.

LASIK surgery takes less than 15 minutes to perform. Most patients experience improved vision immediately, although complete LASIK surgery recovery can take up to six months as vision takes some time to stabilize following surgery.
Following LASIK surgery, patients can expect a short recovery period. You may be required to wear a protective shield over your eyes for the first night or two following procedures. Your doctor may also instruct you to take antibiotic, anti-inflammatory, or moistening eye drops, and to wear dark eyeglasses if you experience sensitivity to bright lights.
Although LASIK complications can occur, most vision correction patients are able to return to work and other daily activities the day after the procedure. There is usually little to no discomfort after LASIK surgery and follow-up exams during recovery are required to ensure that your eyes heal properly. It is recommended that you go to sleep right after LASIK surgery to reduce post-operative pain. When you wake up, you should already notice improved vision.
Nearsighted patients who undergo LASIK surgery typically return to functional vision the day after the procedure. Although some patients experience difficulty reading the first few days, this is normal, as it may take one to three months for final vision to stabilize.
Farsighted LASIK surgery patients usually experience dramatic results the day after LASIK. Although distance optics may appear blurry, this is also temporary.
Generally, it is considered more difficult to correct astigmatism than farsightedness or nearsightedness. Nevertheless, LASIK surgery statistics show that many astigmatism patients are still LASIK candidates and can achieve great results and dramatically improved vision.
After LASIK surgery, you should lie down, relax, and close your eyes. Watching television, reading, or operating a computer should be avoided for the first 24 hours. The LASIK surgery recovery process requires your eyes to remain relaxed.
Do not rub your eyes. Protective eye shields should be worn for the first seven nights. Some patients report a mild burning sensation two to four hours into the LASIK surgery recovery as they anesthetic wears off. The sensation resembles wearing an itchy or dirty contact lens.
Wear sunglasses after surgery – rain or shine. Take baths instead of showers for the first 24 hours after surgery and be careful not allow the shower to spray directly into your face for the first week. Use a face cloth and be careful not to rub your eyes. Avoid eye makup and smoky or dusty environments for a week. Avoid alcohol consumption for 48 hours after LASIK surgery.
Your surgeon or ophthalmologist will schedule follow-up appointments to monitor your LASIK results and potential problems such as epithelial growth. Contact your physician immediately if you experience any complications.
