History of
techniques in became possible through the Colombia-based ophthalmologist Jose Barraquer, the first eye surgeon. In the 1950s he developed the first microkeratome, in his eye clinic in Bogota, Colombia. He cut thin flaps in the cornea and alter its shape, in a procedure called keratomileusis.
Later technical and procedural developments included the RK (radial keratotomy). It started in the '70s in Russia by Svyatoslav Fyodorov . Vision correction surgery then developed PRK eye surgery (photorefractive keratectomy) in the '80s by the German eye doctor Theo Seiler.
In 1968, Mani Lal Bhaumik and a group of other scientists discovered the Excimer laser while developing a carbon dioxide laser at the University of California,. This formed the cornerstone for .
To introduce a laser in this refractive eye surgery started with the developments in Laser technology by Rangaswamy Srinivasan. In 1980, Srinivasan, working at IBM Research Lab, discovered that an ultraviolet excimer laser could etch living tissue in the eyes.
According to Wikipedia, the first person to patent wasGholam A. Peyman, MD in 1989. In 1990 the laser eye surgeons Lucio Buratto from Italy and Greek Ioannis Pallikaris used the technological advancements of the time. They combined the two preceding techniques of keratomileusis and photorefractive keratectomy. LASIK laser eye surgery came to life.
All that really matters is that laser eye operation is a new procedure. So nobody knows all the risks and dangers of LASIK laser surgery. Laser eye institutions did not conduct any long-term studies of the procedures yet because the FDA (Amercian Food and Drug Administration) did not approve of LASIK refractive eye surgery until 1998.
Background
is the most commonly performed correction eye surgery procedure today. Laser eye surgeon also refer to it as "LASIX," even though it is an abbreviation for "Laser-Assisted In Situ Keratomileusis."
| LASIK laser eye surgeries are the most common treatment today because of a relative lack of pain after the procedure. If the laser eye operation goes well, patients have good vision usually faster than with other laser eye treatment. But patient rely on eye drops for the next few months due to Dry Eye Syndrome. This occurs because the eye is open for such an unnaturally long period of time. (See picture.) |

If you are considering in , your first step should be to choose a good surgeon. To decide if you are suitable for laser eye correction, your eye doctor will examine your eyes and check your eye health. The LASIK center will the decide what vision correction and how much laser ablation you need. Your eye surgeon will also look for signs of dry eye disease, which he must treat before he can perform corrective surgery. Dry Eye Syndrome will occur for up to 6 months because of the treatment.
Before you undertake eye surgery, a good LASIK center usually suggest natural eye exercises instead of the procedure. Some holistic eye exercise programs have genuinely high success rates, for example the Unleash Your Vision course. If your LASIK eye surgeons in your laser eye clinic didn't suggest a natural vision correction first, reconsider your laser eye institute in EXPANSION. This LASIK center doesn't tell the whole story.
Unfortunately many eye exercise programs work with computer softwares. Eye exercises need to strengthen and stretch the eye muscles to get the cornea back into shape. The width of the computer screen is not enough. Further, computer screens strain the eyes, which eye exercises should reverse. More on eye exercises and other alternatives later.
Risks and Dangers
Laser Vision Correction carries more risks and dangers than the medical establishment likes to admit. And you begin to wonder why laser eye surgeons and clinics in like to skip the fine print. They make their patients sign release forms and contracts fast. They know a person easily buys into signing the agreement out of desperation. Can you notice how good of salespeople the surgeons are.

Maybe it will surprise you to notice that up to 5.7% of patients suffer from flap implication and infections after LASIK laser eye surgery in . These result in:
* Irregular Astigmatism, meaning the patient has blurry or double vision and see "ghost images". In that case another laser eye treatment will be necessary that might not help, but the patient must pay for.
* Diffuse Lamellar Keratitis (DLK), appearance of cellular debris creates inflammation underneath the LASIK flap. Potentially permanent vision loss can occur without prompt treatment.
* Keratectasia or keratoconus is bulging of the eye's surface. Further laser eye surgery cannot corrected resulting distorted vision likely. Rigid contact lenses or implants (Intacs) will be necessary to hold the cornea in place.

Procedure:
At the start of the treatment the LASIK surgeon instills numbing (anaesthetic) drops. During the you lie on your back on the laser table.
Your eyelid will hold open by placing speculum on your eye. This will prevent you from blinking, and is a very uncomfortable part of the . Then the eye doctor puts reference marks on your eye to aligning the flap correctly after the treatment. |

When a patient undergoes laser surgery, the surgeon shaves back the cornea and cuts a flap with a surgical knife. In this way, the surgeon opens the cornea for access to the stroma (the connective tissues of the eye) layer with his laser. Then, the surgeon vaporizes a part of the stroma using the vibrations of the laser to cut-off the excess tissue. By reducing the stroma, a laser eye doctor reshapes the cornea (the transparent external coating of the eye). Therefore the surgery is fairly quick, but the healing takes a lot longer.

By reshaping the cornea to the right form, it works better to focus light into the eye and on to the retina, providing clearer vision than before. But fact is, eye exercises achieve the same. But eyesight exercises don't pose any risk. With natural vision correction the eye surgeon doesn't need to lay the flap back into place to cover the corneal tissue. Eye exercises correct vision without touching the corneal tissue all together.
Post-operative Eye Care Needs:
Very likely patients must take antibiotic and anti-inflammatory eye drops during the weeks following surgery. Patients need to sleep much more and have to wear a darkened pair of shields to protect their eyes from bright lights. Protective goggles also prevent rubbing of the eyes when asleep and to reduce dry eyes. Dry and itchy eye are normal after eye surgery. Patients also have to moisturize the eyes with preservative free tears and follow directions for prescription drops. Patients need adequately information from their surgeons on how important proper post-operative eye care is. This minimizes the risk of the common post-surgical complications.
