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.
What is LASIK Eye Surgery and is it Suitable For You?

Everywhere you look there seems to be ads for LASIK eye surgery. The way they advertise the procedure can make you think that is will be the perfect solution to your vision problems. No more straining to read the ingredients on food packets or road signs. Simply undergo LASIK surgery and all there hassles will be a thing of the past.
However it is important to note that LASIK eye surgery may not be suitable for everyone so it’s important to read up as much as possible out the procedure.
The acronym LASIK means laser in-situ keratomy, eye surgery and uses an excimer which is a powerful laser. These have been specially designed to work on the delicate eye area. The laser can quickly re-shape the cornea (for treating nearsightedness) or the hyperopia (for treating farsightedness).
When the cornea is reshaped what happens is that tissue underneath is removed. So that the tissue can be worked on, a very small flap is pulled back from the surface of the cornea. The laser or microkeratome blade can be used to create this flap.
The laser zaps away excess tissue determined by the ophthalmologist whilst viewing an extremely detailed image of the cornea. This process can take only a matter of minutes and the patient won’t feel a thing. Vision can be corrected so swiftly that they are able to drive home aftwards.
The primary consideration when deciding if LASIK is for you is to look at the costs involved. Many health plans don’t cover this procedure as they believe it to be purely cosmetic.
The cost of surgery can vary greatly however the costs generally reflect the use of a reliable and experienced ophthalmologist and will cost several thousand dollars per eye. The cost is certainly not insignificant.
Cost isn’t the only consideration however. You can only undergo surgery if you have healthy eyes which have stopped changing. Other situations can also arise which prevent surgery.
When you go for your first consultation a number of tests will be performed to detect eye problems or diseases which could cause problems with the surgery. Because of hormones, LASIK surgery cannot be performed on pregnant women or on people with suppressed immune systems.
If you have the money to spend on surgery then LASIK may be a good way to improve your vision. The success rate is very high and the procedure is painless. There aren’t many reasons not to go ahead with treatment.
The Benefits Offered By Bladeless LASIK Eye Surgery

The risks involved in LASIK eye surgery is relatively small compared to other types of surgery. However, there is still a risk which is there because of the use of the blade that is used to cut the flap in the cornea. The use of this blade comes with the element of human error. This is because all human beings make mistake from time, although this risk is reduced the more highly trained someone is. However, this risk is still there.
Bladeless LASIK lowers that already small risk even further as it removes the need for a blade. This function is taken over by IntraLase lasers which are controlled by computers and can therefore provide a more precise cutting action. Because bladeless LASIK is so delicate that it can even be used on people who have thin corneas. These are people who usually not approved for other types of laser surgery.
Bladeless LASIK offer a number of advantages. The IntraLase laser used during bladeless LASIK allows for an increased curvature, hence lowering the margin of error even more. The fact that a laser is used instead of a blade leads to less infections and irritation. Not only that, bladeless LASIK only leads to a shorter recovery period compared to other types of LASIK eye surgery.
Before bladeless LASIK, many people who had surgeries had to come back for follow-ups or to redo a surgery that didn’t go so well. There is also a great deal of irritation that follows other surgeries. However, with bladeless LASIK most of these are something of the past, because of a success rate that is very close to 100%.
So now you may wonder, why do we need an eye doctor for if the lasers are doing everything? Well even though many of the actions are controlled by lasers, these lasers still have to be directed. And to be able to do that you need to have the knowledge of both laser technology as well as eye surgery, which only a trained LASIK eye surgeon can give you. Surgeons who do bladeless LASIK now also need to know how to operate the computer that controls the InterLaser lasers.
Although bladeless LASIK may cost a bit more, many people think it is worth spending that extra money, considering the near perfect results you get. Not to mention the reduced irritation and shorter recovery time.
