LASIK 101: Introduction to Laser Vision Correction

Seth A. Biser, M.D.

Almost every person who is seriously considering Laser Vision Correction has dozens of questions. “Will I actually be able to see without glasses or contact lenses?” “Is it safe?” “Will it last?”

This brief, general introduction to Laser Vision Correction will answer the initial questions asked by most patients. Since 2001, I have performed over 2,000 cases, each with careful attention to individual patient needs. If you have any questions about your own personal candidacy for Laser Vision Correction, please call!

What is Laser Vision Correction?

It is a precise treatment to correct nearsightedness, farsightedness, and astigmatism in which a “cold” excimer laser gently reshapes the cornea (the clear shield on the front of the eye). The three main subtypes of Laser Vision Correction are LASIK, IntraLASIK, and PRK. These are discussed in more detail below.

Who can have Laser Vision Correction?

Patients must be at least 18 years old and have good, stable vision in both eyes with glasses or contact lenses. Because many 18-year-olds still have changing vision, my youngest patients have typically been 20 or over. Patients must also pass a series of preoperative diagnostic tests to make
sure that they are good candidates (in other words, that the procedure will be safe for them).

What is the procedure like?

The eye is numbed with drops, and a device comfortably prevents blinking while the cornea is prepared for the laser. The patient focuses on a small red flashing light as the treatment begins. Sometimes, the patient will actually see the vision improving second by second during the laser application. The entire procedure typically takes 5-7 minutes per eye.

When will I start to see better?

The initial effect is immediate: patients sit up and easily read a clock across the room. Although the vision at this early stage is reasonably good, further clearing of vision will come later, and varies by procedure.

What will my vision be, and will it last?
While individual results may vary, nearly all patients achieve 20/20 vision in a single treatment. With higher or more difficult prescriptions, an enhancement, or “touch-up,” may be needed to achieve perfect vision. However, my enhancement rate is less than 1.5%, so my first-treatment results tend to be highly accurate. Once the final vision is attained, it tends to stay stable for many years; a full description of stability is found in on the link to LASIK 102.

What are LASIK, IntraLASIK, and PRK?
In both LASIK and IntraLASIK, laser is applied under a thin “flap” made in the cornea. In LASIK, this flap is created mechanically. In IntraLASIK, this flap is created with the Intralase machine, using laser energy. IntraLASIK is often known as “all-laser LASIK.” In PRK, no flap is created; the cornea is prepared with a gentle brush that smooths the surface of the cornea.

Is it Safe?    

Yes, laser vision correction is an extremely safe, time-tested, FDA-approved treatment. However, there are risks with any eye surgery, and prevention of problems is the most important step! I start with rigorous preoperative testing to see whether each patient is truly a good candidate. Issues such as dry eye syndrome, blepharitis, subtle corneal dystrophies, and other eye conditions must be addressed and managed before the procedure to achieve optimal results and a comfortable and successful outcome. Many additional safety measures are followed before, during, and after surgery. As a result of being careful with preparation, I have maintained an excellent record of both safety and accuracy in my postoperative patients.

What model of laser do you use?

I primarily use the VISX Star S4-IR with CustomVue. I also have access to the Technolas 217z. Both lasers use eye-tracking technology and offer Wavefront-guided treatments. For IntraLASIK, I use the 60-Hz (FS60) Intralase, which creates ultra-safe flaps in just 15 seconds. This amazing technology has greatly improved the safety and precision of laser vision correction.

Can I Afford It?
Most patients say yes! My rates are very reasonable and very competitive. With flexible spending accounts (allowing payment with tax-free dollars) and financing plans available, Laser Vision Correction is probably within your reach. Most patients decide that it is less expensive than repeatedly paying for new glasses and contact lenses.
