Laser Vision Correction

Athletic couple running on beachHow well you see depends on the shape of your cornea. The cornea is the eye’s clear layer that covers the iris, pupil and anterior chamber. In nearsighted people, the cornea is too round, while in farsighted people, the cornea is too flat. When someone is diagnosed with astigmatism, it means that they have an irregularly shaped cornea. There are various refractive surgery procedures that can correct nearsightedness, farsightedness and astigmatism. At Coastal Vision Medical Group we perform the best vision correction procedure to meet your specific visual needs.

Dr. Tran was the first surgeon in the world to use a commercial femtosecond laser back in 2001, creating an all-laser LASIK. This all-laser LASIK is considered premium LASIK because the flap is created using a laser as opposed to a blade. With all-laser LASIK, people with thin corneas who are unsuitable for LASIK may now be candidates due its precision and its ability to consistently produce corneal flaps thin enough to treat those patients who were previously not candidates.

Our surgeons at Coastal Vision use the Ziemer FEMTO LDV Z4 femtosecond laser and the Alcon Wavelight EX500 refractive laser suite which comprises the 500 Hz excimer laser and the 200 kHz femtosecond laser, the fastest refractive laser platform in the U.S.

What is LASIK?

LASIK (Laser-Assisted In Situ Keratomileusis) is currently one of the most frequently performed elective procedures in the United States. It is a highly effective vision correction procedure used to correct most ranges of nearsightedness, farsightedness and astigmatism. LASIK is an outpatient surgical procedure that uses a cool laser beam to gently reshape the surface of the cornea. This causes little or no discomfort and improves vision. The beam gently pulses to remove a microscopic amount of tissue, allowing images to be more sharply focused on the retina.

The LASIK procedure is generally safe, effective, and has very few side effects. LASIK is a great option for many individuals considering laser vision correction for a variety of personal and professional reasons. LASIK may not promise perfect vision, however; it is a highly successful procedure, that can at the very least reduce a person’s dependence on glasses or contact lenses. The lifestyle benefits can be tremendous for active and social people. These benefits can enable people to more freely pursue their hobbies, sports activities or career options.

LASIK is a non-invasive, refractive procedure using the technology of the excimer laser along with a femtosecond laser that creates a thin flap. LASIK uses a beam of cool light to reshape the top layer (less than 10 percent) of the cornea, so that images focus correctly on the retina. A computer, controlled by your LASIK eye surgeon, is used to precisely calculate the exact amount of cornea that needs to be removed for each person’s individual eyes. Numerous tests will be done on the eyes to achieve the measurements that will be treated with the laser. During LASIK, the femtosecond laser will be used to create a thin flap from the surface of the cornea. The flap is then lifted to expose the deeper layer of cornea to be treated. This corneal flap stays attached to the rest of the cornea on one side. The laser is then positioned into place, and delivers a programmed number of pulses of ultraviolet light onto the newly exposed part of the cornea. Each pulse of the laser removes a microscopic layer of cornea. After LASIK surgery is complete, the corneal flap is put back in place. This flap will naturally adhere to the treated cornea, eliminating the need for sutures. Pressure from the eyelid and other factors will hold the flap in place as it heals, minimizing discomfort. The center of the cornea is now flattened, allowing light rays to be focused more precisely on the retina and images will be seen more sharply. Most LASIK patients notice a dramatic improvement in their vision immediately after the procedure. However, maximum improvement will occur over the next three to four weeks. Both antibiotic drops and steroid drops will be used for a period of two weeks following LASIK surgery to ensure proper healing. Artificial tears will also be used abundantly to help keep the cornea smooth and moist during the healing period.

Understanding Your LASIK Candidacy

There is perhaps nothing more important in the LASIK eye surgery process than determining your candidacy. If you are familiar with someone who has not had a good result the problems typically stem from poor judgment of candidacy. The candidacy process begins with a thorough eye health evaluation to check the overall health of your eye as well as the corneal thickness.

During your initial free LASIK screening, we will thoroughly examine your eyes and perform comprehensive testing to make sure that LASIK eye surgery is the right procedure for you. A medical and eye history will be taken and several tests will be performed, including:

  • Dry eye testing
  • Visual acuity and refractive error
  • Pupil size in low & medium light
  • General health of the eyes
  • Corneal topography & corneal thickness

Refractive surgery can also be performed by exchanging your natural crystalline lens with an Intraocular Lens (IOL). Lens implants are for people who find that their prescriptions fall outside the accepted range for laser refractive procedures. The available options include Clear Lens Exchange, the Phakic Intraocular Lens or Implantable Contact Lenses (ICL).
