Lasik eye surgery new york
The history of modern day procedure of vision correction can be traced back to the year 1948 in Bogot, Colombia where Dr Jose Barraquer followed a procedure of removing 60% of the cornea, freeze it reshape it using a lathe. The cornea was then sewn back into place. This procedure which was termed as Freeze Myopic Keratomileusis was the first step in vision correction surgery. Though this procedure appeared to be very risky, and results unpredictable, it however it provided necessary knowledge as to safely handling the cornea and experiment further to achieve sustainable results.
Through trial and error doctors made many modifications and thus Automated Lamellar Keratoplasty came into existence in 1960s. Here a microkeratome was used to create a corneal flap then remove a wedge of corneal tissue from underneath the flap and thereby correct the shortsightedness of the patient. But this also gave inconsistent results. In the 1960s Fyodorov, a Russian ophthalmologist also brought in some innovations to correct myopia and astigmatism. The following many years found doctors studying how to treat the cornea with less percentage of incision, and an accurate and comfortable procedure with fast recovery.
This lead to the finding of excimer laser which was first developed by the US army and the later in 1983 ophthalmologist Steven Trokel made some modification and it turned to be a great improvement, mainly due to the excimer laser. This can be marked as the modern era of laser correction. In 1991 1st LASIK procedure was performed in the US. It utilized decades of research and refinement to provide an absolutely accurate, comfortable procedure with a fast recovery time.
Defining Lasik Laser Surgery.
The name LASER is an acronym for Light Amplification by the Stimulated Emission of Radiation. (In 1917 Albert Einstein first theorized about the process which makes laser possible called stimulated Emission).
Surgical procedures that can improve or correct the eyes focus by permanently changing the shape of the cornea is called Refractive Eye Surgery. The surgery is relatively painless, and full recovery is attained in few days. The whole surgerical experience takes only less than 20 minutes in most cases. Maximum number of patients walk out after the surgery within hours and are seeing better than they have seen in years.
Medical Encyclopedia defines Lasik eye surgery new york and the procedures more elaborately. It says that Lasik is a surgerical procedure that can reduce a person*s dependency on glasses or contact lens. The procedure permanently changes the shape of the cornea (the delicate clear covering on the front of the eye) For clear vision the eyes cornea and lens must bend (refract) light rays properly so that images are focused on the retina.If the light rays are not properly clearly focused on the retina the images you see are blurry. This blurriness is referred to as refractive error. It is caused by an imperfectly shaped eye ball, cornea or lens.LASIK uses an Excimer Laser(an ultraviolet laser) to correctly remove corneal tissue to correct the shape for better focusing.Lasik eye surgery is performed most often on people who have nearsightedness (myopia) which mean that they see only nearby objects; any thing far away is blurry.
Procedure
The doctor will do a complete examination of the eye to ensure that the eye has no other complication, and is healthy. The procedure will take only 15 minutes for each eye. The only anesthetic used is an eye drop that numbs the eye. However the patient stays awake throughout the surgery. There are no stitches.
The FDA in corporation with the American Academy of Ophthalmology has recorded the following guidelines and recommendations:
* Should be at least 18 years old (21 for some) as the vision of people younger than 18 usually continue to change.
* Should not be pregnant or nursing, because these condition may change the measured refraction of the eye.
* Should not be taking certain prescription drugs such as Accutane or oral Prednisone.
* Eyes should be healthy and prescription stable. If myopic postpone LASIK until your refraction has stabilized because myopia may continue to increase in some patients until their mid to late twenties.
* Should be in good general health. LASIK may not be recommended for patients with diabetes, rheumatoid arthritis, lupus, and glaucoma, herpes infection of the eye or cataract. Understand expectation from the surgery. Be realistic. For patients with presbyopia Lasik eye surgery new york cannot correct so that one can see at both, distance and near.
However LASIK can be used to correct one eye for distance and the other for near. If one can adjust to this correction, it may eliminate or reduce the need for reading glasses. In some cases surgery only one eye is needed. Always discuss the pros and cons with the doctor.
The FDA also enumerates the risks generally involved in this surgery.
* Over- or under-treatment of the condition may occur, requiring additional surgery, contact lens, or glasses.
* Reading glasses may still be needed after surgery.
* Some patients, although they may see much better than before LASIK without glasses, will still need glasses for their best vision.
* Problems with night driving or visual symptoms, such as glare and haloes.
* Problems with a decrease in contrast sensitivity, and even with 20/20 vision, objects may appear fuzzy or gray.
* Corneal infection.
* Corneal scarring, permanent warping of the cornea and an inability to wear contact lenses.
* A loss of vision -- not seeing as well after surgery, even with glasses or contacts as before the surgery.
* Permanent vision loss.
* Flap complications.
* Light sensitivity.
* Dryness.
* Scratchiness.
* Patches of red or pink in the white of the eye.
* Decreased distance vision at high altitudes.
However the Lasik eye surgery new york is one of the profoundest achievements that medical science has achieved in the field of eye treatment. Undoubtedly shortsightedness in human being poses an obstacle in the overall development of ones personality. Especially because it targets the younger generation.A clear vision nevertheless scores higher than a blurred one in all walks of life.
