Dr. William Boothe Offers a Solution for Nearsighted People

Filed under: Boothe Eye Care — Doctor Boothe Eye @ 7:03 pm

What does shortsightedness do to your eyes?
Your eye as an optical system that consists of two structures:

• The cornea and lens, which is the light refrecting element, such as an analog camera lens
• The retina, which is the light receptive part with the nerve endings going to the brain,

With shortsightedness (myopia), light rays are focused not on the retina of the eye, but beforeit, so the visual image on the retina falls”out of focus.”

Incidentally, the very fabric of the cornea – optical biological tissue – is a scientific mystery.Scientists still cannot explain why the living tissue is transparent,but the use of its properties has already been learned.

What can a laser do with your eyes?

Laser eye correction can help obtain a clear picture in two ways. First, the correct focal distance from the “lens” of the cornea to the retinais corrected. Second, the “lens” is replaced so that the refractive power of lens-corneal allows retina be in focus. For this Dr. Boothe uses the laser to change the profile of the cornea.Redesigning the cornea is the essence of laser correction procedure.

a. Myopia is treated by using the laser to remove the corneal tissue from the central zone and the cornea becomes flatter

b. Hyperopia is treated by using the laser to remove the corneal tissue from the periphery, and the cornea becomes more convex

c. Astigmatism is treated by using laser to remove corneal tissue from variousareas so that the cornea becomes uniform.

Excimer laser situ keratomileusis (Lasik)

Today Lasik eye correction surgery is the latest in laser vision correction. This method of laser correction combines microsurgical and laser techniques.For 2-3 seconds a microsurgical automatic machine – the microkeratome – cuts the corneal epithelium in the form of a circular flap of 8 mm diameters on a stalk and leans back, like a lid.Then, using a laser beam, parts of the cornea are evaporated, creating a new profile.Then the “lid” – a flap of epithelium – is closed.No seams, and recovery time of the epithelium is not required, as the protective layer of the cornea is not damaged, so the patient does not experience discomfort after the surgery. It is possible to have laser eye correction on two eyes at once.

An important advantage of laser correction of myopia is that it does not involve, in contrast to all other surgical procedures, no new limitations in the future.However, the chance of deteriorating health in general or after the operation is not higher than the possible side effects and complications of wearing glasses or contact lenses. Laser surgery is also attractive because it is:

  • Completely contactless (laser eye surgery is performed by means of the light beam), which eliminates the risk of infection
  • Painless
  • A quick and easy operation
  • Done using precise calculations withcomputer technology so the results are the best possible

Laser vision correction surgery is a huge advancement of modern ophthalmology. Due to achievements in the field of laser eye surgery, it is now possible to solve the problem of poor vision for millions of people with various forms of refractive errors. Over the past 10 years more than 5 million vision correction procedures using the excimer laser have been performed. In 2010 alone, 1 million of these procedures were performed.

History of Laser Eye Surgery

In the mid-20th century, attempts to radically change poor vision with microsurgical eye operations were made. The fruitful idea of correcting the optical properties of the cornea, instead of using external “crutches” for the eyes in the form of eyeglasses or contact lenses has led to the development of many variants of surgical vision correction procedures.
Initially, such eye surgeries were based on direct intervention in the cornea of the eye by performing special cuts and incisions using microsurgical instruments. These “method cuts”, “method of Federov”, or “radial keratectomy” gained much popularity. This method of surgical correction of vision was used for a long time.

Excimer Laser is a Revolution in Modern Ophthalmology

The introduction of the excimer laser in ophthalmology practice was a technological breakthrough in surgical vision correction. The beam of an excimer laser is extremely precise and carefully affects the cornea. The laser “vaporizes” corneal tissue to only 1 / 8 of its thickness. Modern computer systems for excimer laser vision correction has made it possible to correct virtually all types and degrees of refraction.

Scientifically speaking, excimer lasers are precise systems that provide the necessary “photochemical ablation” (evaporation) of the layers of the cornea. If the tissue is removed in the central zone, the cornea becomes flatter, which corrects nearsightedness. If, however, the laser evaporates the peripheral part of the cornea, then the center will become more “cool” which corrects hyperopia. Dosed removal in different meridians of the cornea corrects astigmatism.

Modern Methods of Laser Vision Surgery

Currently, Boothe Eye Care & Laser Center uses the two most popular technologies in the excimer laser vision correction:
• Traditional Lasik surgery
• IntraLasik or “all-laser” surgery
IntraLasik is a new laser refractive surgery that allows the correction of vision without scalpels and mechanical blades. During this all laser surgical procedure Dr. Boothe creates a flap on the cornea with a Femtosecond laser instead of a microkeratome (mechanical blade). Then the laser is used to reshape the surface of the cornea, correcting the patient’s vision.

What can be expected on the day of my vision correction procedure?

• If possible, bring the results of previous vision surveys that you have taken
• Before performing eye examination do not wear soft contact lenses for a week, hard contact lenses for 2 weeks
• Do not use any cologne, perfume, or deodorant on the day of the correction
• Please do not wear wool or mohair sweaters with a high neck on the day of the correction
• For women patients: do not use any cosmetics one day before the correction and also on the day of the correction
• Do not drink alcohol for two days prior to the correction

If you do not comply with the requirements for vision correction surgery, Dr. William Boothe may refuse to provide you with an eye survey or laser eyesight correction procedure.
Please arrive at the clinic an hour and a half before your scheduled vision correction procedure.

After your vision is checked, you will be prepared for the procedure. The area around your eyes will be cleaned; you will be dressed in sterile surgical boots, a coat, and a hat. The nurse will take you into the laser operating room, where you will have to wait for Dr. Boothe. The nurse will apply anesthetic drops into your eyes. After that, the eyelids will be held open for the procedure using a blepharostat.
Dr. Boothe programs the excimer laser according to the data that was obtained during the refraction survey. After that, the microkeratome instrument, designed to create the thinnest flap will be installed on the eye surface. During the microkeratome work you will feel a little pressure, but no pain. After that Dr. Boothe gently push the flap aside and ask you to look directly at the red light in front of you and if possible to not move the eye.

However, even if at the time of surgery you move your eyes, do not worry because the computer is equipped with a special tracking system that tracks your eye position during surgery. The laser beam will turn off if the eye has deviated from the desired position.

Laser eye surgery can last up to 10 minutes, depending on the degree of refractive error and patient behavior. During the laser treatment you will hear clicks and you may smell something. The surgeon will warn you of these things. After the procedure, the flap will be returned to its place, and you will be done!
For the remainder of the day, you should rest and strictly adhere to the instructions of Dr. Boothe. You may feel some discomfort, which will be eliminated with special eye analgesic. In some rare cases there may be a light hypersensitivity and watering of the eyes for 1-2 days.
