LASIK Eye Surgery Requires Careful Consideration
Alex Rider asked:
If you are thinking about having LASIK eye surgery consider the fact that some people may be unsuitable for this operation. LASIK surgery should possibly not be conducted on you if:
Your career could be subsequently placed on the line as a result of an eye operation. Various jobs implicitly state that eye modifications are prohibited, therefore it is imperative that you talk with your employer first.
Money is hard to come by at the present time. Currently, the majority of medical insurance doesn’t pay for surgeries of a refractive nature. Costs appear to be falling but still remain very high.
You are adverse to taking risks. A number of patients always receive particular complications. Additionally, since no long-term studies on LASIK have been performed you are effectively a guinea pig.
Your eyes are still changing yearly. If your glasses prescription has been modified within the last year constant surgical revisions would prove too costly and damaging to the eye. Eyes that are typically still changing are found in people 20 years of age or younger, those with diseases like diabetes that cause hormone imbalances, pregnant or breastfeeding women, and people taking medication that affects their clarity of vision.
You are an active contact sport participant. Wrestling, boxing or martial arts involve many strong hits to the face and in particular the eyes.
You have a disease or medications that mean any wounds you receive will heal slowly. Particular ailments like states of immunodeficiency (e.g. HIV), autoimmune disease (e.g. rheumatoid arthritis, lupus), and some medications (e.g. steroids and retinoic acid) can stop an eye healing after refractive surgery has been administered.
Your age is not 18 or older, since under this age this procedure is illegal.
Surgical safety and efficacy has not been established with people who have particular diseases. Talk with your doctor if you have a potential medical background associated with:
herpes zoster (shingles) or herpes simplex
disease of the eye (e.g. inflammations of the eye; iritis/ uveitis)
If you are considering having eye surgery your doctor will need to run tests to see if you have other risk factors like:
Thin corneas. This clear covering over the iris of the eye is what is generally modified in refractive surgery since it holds the most power with regards to the eyes ability to focus. If thin then complications that could result in blindness increase in probability.
Dry eyes. This condition tends to be promoted by LASIK surgery.
Blepharitis. This inflammation of your eyelids and associated crusty deposits on the eyelashes can further your chances of getting an inflamed and infected cornea during the post-op recovery period.
Past refractive surgery such as PRK, RK or LASIK may prohibit further surgery to the eyes. When this is the case you have to consult your doctor about your specific situation.
Oversized pupils. Evaluations should be made in professional dark rooms. People who are young or are on particular medications may under dim lighting have larger than normal pupils. Such eyes are prone to symptoms such as halos, starbursts, glare or double vision (ghost images) following surgery. For some patients these visual complications can end up being highly debilitating.

Lasik Eye Surgery Procedure – Extremely Precise Vision Correction

The most commonly used refractive surgery procedure is the lasik eye surgery procedure and this is a very popular form of surgery that has the advantage of being less painful and resulting in a 20/20 vision in most cases, usually on the very next day.
The basic lasik surgery procedure involves an instrument which is known as a microkeratome which is used in the surgery to create a thin and round flap in the cornea. The surgeon will take the flap and fold it back so that it is not in the way and then takes away some corneal tissue that is underneath with the help of an excimer laser which uses cool ultraviolet light beams to exactly remove very small bits of tissue from the cornea in order to reform it.
Once the cornea is reformed into the correct shape it will work in an improved manner and focuses light into the eye as also onto the retina thereby getting the person to see clearly which will be better than what it was before the lasik eye procedure. Afterwards, the flap is replaced back in place and covers the area where the corneal tissue had been removed.
Corrects Nearsightedness, Farsightedness as well as Astigmatism
Lasik surgery procedure is helpful for nearsighted as well as farsighted people. In the case of nearsightedness the aim is to flatten the extra-steep cornea and with farsightedness, a steeper cornea is required. Excimer lasers are also used to rectify astigmatism through smoothening of the irregular cornea and getting it into a more normal shape and the lasik eye procedure will help to achieve this.
There are certain steps to follow before getting your lasik eye procedure performed and these include choosing a good surgeon, finding out whether you are the right person for this type of surgery as well as finding out whether you have any dry eye diseases which need to be treated and cleared prior to the lasik eye procedure.
There are different types of lasik eye procedures such as blade versus bladeless and also custom lasik or wavefront lasik procedures. The wavefront-guided lasik eye surgery procedure makes use of 3-dimensional measurements that figures out how the eye processes images and this is helpful for guiding the laser in reshaping the front portion of the eye that is called the cornea. The wavefront measurement of the lasik eye surgery procedure is extremely useful in extreme and precise individualized vision correction.

Risks of Lasik Eye Surgery
Carson Danfield asked:
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.

Lasik Eye Surgery Risks Include Loss of Vision

anonymous asked:
Most often, patients of lasik eye surgery are pleased with the results of the refractive surgery but they should be aware that it does involve certain risks and that is why it becomes necessary for them to understand the various types of lasik surgery risks.
This would involve studying and understanding the possible risks which may include losing vision, developing a debilitating visual symptom, under-correction or over-correction or developing severe dry eye symptoms. Some patients have disappointing results and refractive errors that may occur, farsighted patients may see results diminish with age, and also there is not enough long term data available to ensure long-term safety and effectiveness of lasik surgery.
Device Malfunction, Flap Migration, Inflammations and Infections
In addition, there are other lasik eye surgery risks such as malfunction of devices used in the procedure, migration of the flap, and inflammation or infection developing. There are instances when a patient loses lines of vision on the vision chart that may not be able to be treated by glasses, contact lenses or surgery and this is a grave lasik surgery risk.
There may also be lasik eye surgery risks such as the patient developing glares, halos and/or double vision that may seriously hinder nighttime vision and the patient may not be able to see well in low contrast situations. The numbers of patients who achieve 20/20 vision as a result of lasik surgery are few and so may need additional treatment though such additional treatment may not always be possible. This is another lasik surgery risk.
There is also considerable lasik eye surgery risk in that the patient may not be able to produce enough tears so that the eye remains clean as well as moist and comfortable. There is considerable discomfort caused by dry eyes and it may reduce the quality of vision because of intermittent blurring as well as other symptoms of vision. Such a condition may sometimes become permanent and may require intensive drop therapy as well as using plugs or some other procedures for treatment and is certainly another serious lasik surgery risk.
The patient would be well advised to discuss with the doctor their expectations and be prepared that sometimes the results would not match high expectations. In case of farsighted people, the amount by which the vision can be improved as a result of having lasik eye surgery would decrease as one grows older and this may be another lasik surgery risk. Also, there is not enough long term data to help the medical professionals glean more knowledge about this relatively new technology and so the long-term safety and effectiveness of lasik eye surgery is not really known.

Lasik Eye Surgery – Understanding Its Different Types
Ventura Eye Institute asked:
When it comes to the matter of eye surgery, the first thing that comes to our mind is Lasik surgery. For corrective vision procedures, Lasik surgery is all what we think about. There are various alternatives to Lasik surgery today. You can choose the option that rests upon your eye condition, the surgeon who is going to operate and the budget you are comfortable in paying. Hence it is important for you to know the different types of Lasik surgery available so that you make the right click.
LASEK SURGERY: This type of surgery is a refractive procedure that uses alcohol to separate the outer layer of the cornea. The recovery time with Lasek surgery is longer as compared to Lasik surgery. It is useful for people with thin cornea.
PRK: It removes the epithelium with a metal surgical tool. The tissue is removed from the cornea under this treatment. It is a longer recovery process and is suitable for people with thin cornea and large pupils. It is effective for treatments including near-sightedness and far-sightedness. As compared to other forms of refractive surgery, ‘dry eyes’ is the most common complication of this surgery.
EPI-LASIK: A technique used to reduce dependency of a person on contact lenses or eyeglasses. It is a refractive surgery which is similar to Lasek without any use of alcohol. It makes use of a fine surgical blade that reduces the risk of wide corneal flap. A device similar to a microkeratome (called epi-keratome) slides over the surface of the cornea, just underneath the epithelial layer of cells while suction is applied. Epi-Lasik surgery involves less pain and is a fast healing process.
INTRAOCULAR LENS: It is a form of refractive surgery to change the eye’s optical power. In other words, it is done on the patients suffering from cataract. These intraocular lenses are implanted in the eye by replacing the existing crystalline lens. Most of the intraocular lenses are fixed monofocal lenses matched according to the distant vision. The procedure of surgery in the hands of experienced ophthalmologist takes less than 30 minutes and the recovery period is usually 2-3 weeks.
CK: In this type of refractive surgery, radio waves are passed to adjust the contour of the cornea by shrinking the collagen around it. Conductive Keratoplasty is a very fast procedure and a non-invasive alternative to other types of eye surgery.
Majority of people are not aware of the types of surgery best suited to improve their kind of vision impairment. Hence it is important to be well informed about your health so that you can make the right choice of treatment. Moreover, it is crucial to take advice from friends and relatives who have gone through these procedures while making the right choice of surgeon.
