About LASIK
The Hollingshead Barrett Eye Center LASIK Experience
LASIK, or laser in-situ keratomileusis, is a laser procedure which reshapes the cornea to restore clearer vision with more freedom from glasses. The Hollingshead Barrett Eye Center LASIK experience is defined by the highly advanced, computer-controlled laser used in the procedure. Emitting tiny, ultra-precise pulses of light to prepare and reshape the cornea, this technology offers more customizable results.
Dr. Hollingshead and Dr. Barrett have performed thousands of LASIK procedures and are some of the most experienced providers of LASIK in southwest Idaho and eastern Oregon. As a LASIK patient himself, Dr. Barrett can attest to the life-changing effects of laser vision correction.

The Latest LASIK Laser Vision Correction Technology
Hollingshead Barrett Eye Center is thrilled to bring the most advanced laser system, the WaveLight® Refractive Suite, to the Treasure Valley.
With this laser system, our surgeons provide custom, all-laser LASIK procedures designed to correct microscopic visual imperfections and deliver:
- Clearer, crisper vision (generally includes improved night vision)
- More or complete freedom from glasses
- Rapid visual recovery (most patients seen improvement immediately)
The WaveLight® Refractive Suite brings together two powerful lasers—FS200 femtosecond laser and the EX500 excimer laser—in one combined system designed for speed, accuracy, and superb patient outcomes.
The FS200 is the fastest femtosecond laser available in the U.S., while the EX500 laser operates at 500 Hz to provide fast, accurate, and precise refractive laser treatments. Thanks to the WaveLight® Refractive Suite’s innovative swivel bed design, our eye surgeons use these two lasers in quick succession, preparing the cornea in approximately 6 seconds before administer laser correction at approximately 1.4 second per diopter. This means that patients receive highly precise and reliable laser procedures in a short amount of time, which not only provides crisper, clearer vision but also reduces the potential for post-operative dry eye or night glare.
The acquisition of this technology allows Hollingshead Barrett Eye Center to maintain our commitment to offer patients the safest and most effective vision correction procedures available anywhere.

Dara's LASIK Story
LASIK FAQs
LASIK is a two-step process in which the cornea is first prepared for treatment by creating a corneal “flap.” This flap is then utilized to temporarily expose a deeper layer of the cornea that a laser can precisely reshape to give the ideal corneal curvature to match a patient’s glasses or contacts prescription. The flap is then re-positioned. Re-covering the treated area allows for rapid vision recovery and healing after LASIK.
In all-laser LASIK, two different lasers are used. One laser creates the flap and a second laser reshapes the cornea. The procedure is completely blade-free, allowing for much greater precision than would be otherwise possible.
In the early years of LASIK, or what is sometimes now called “traditional LASIK,” the surgeon would use a hand-held blade called a microkeratome to create the flap. This worked well the vast majority of the time, but numerous clinical studies have proven that all-laser, blade-free LASIK is both safer and provides better outcomes with more patients seeing 20/20 with all-laser LASIK compared to bladed LASIK.
At Hollingshead Barrett Eye Center, our commitment to the very best possible patient outcomes has led us to provide 100% all-laser LASIK to all our patients. This all-laser LASIK offers many advantages.
- Precision
Using the most advanced laser technology, Dr. Hollingshead and Dr. Barrett offer patients a more precise procedure. Greater precision means improved safety and results tailored to meet the needs of each individual patient. Dr. Hollingshead was the first eye surgeon in Idaho to offer his patients the added safety of "all-laser" LASIK technology.
- Speed
When it comes to LASIK, faster is better. The modern LASIK technology makes it possible to perform the entire procedure in approximately 10 minutes.
- Proven Superiority
The same all-laser technology used in Hollingshead Barrett Eye Center's LASIK procedure has been tested and approved by the United States Navy for naval aviators. Previously, LASIK vision correction was off-limits for these pilots because of concerns with vision quality following the procedure. According to the Navy’s studies, the modern technology delivered better quality vision and faster visual recovery time, as compared to procedures that treat the surface of the cornea and those involving a microkeratome (a hand-held, bladed mechanical instrument) for flap creation. NASA followed suit by approving all-laser LASIK for astronauts.
If you are a candidate for LASIK, our team will provide you with pre-surgery instructions. In addition to these, it is our policy that patients remove false eyelashes or eyelash extensions completely 2 weeks before their LASIK procedure. Patients may resume wearing them two weeks after surgery.
You will be taken into the laser vision correction suite, where your surgeon will begin by using a computer-guided laser to prepare the surface of your cornea. You will then be instructed to focus on a blinking green light. Using a laser programmed to recognize your eye shape, your surgeon will reshape the cornea with microsecond pulses to achieve optimum visual clarity. The entire procedure takes approximately 10 minutes, with the healing process beginning immediately after and occurring rapidly.
After the procedure you will go home to rest and use your eye drops. Your eyes will be sensitive to light and irritated for several hours, so you must have a driver on hand for the trip home. Our team will give you and your driver instructions and medications to aid in healing, as well as protective eyewear. You may notice an immediate improvement in your vision.
We recommend that you take a long nap after surgery to promote healing.
LASIK side effects are few and depend greatly upon the individual. Temporary side effects may include minimal discomfort, mild scratchiness, and dry eyes. Glare or halos in low light conditions may occur but are rare.
Due to other medical conditions such as cataracts that are commonly found in eyes after age 55, we do not perform LASIK screenings on anyone 55 or above. Instead, we ask you to schedule an eye exam. You may still be a LASIK candidate, but we need to make sure there aren’t any other conditions that could affect your outcome.
LASIK laser vision correction is not for everyone. Certain factors, such as corneal thickness, the strength of your eyeglass prescription, and underlying medical conditions all help determine whether or not you may be a candidate. You also must have a stable prescription for at least a year prior to treatment. That is why, before any vision correction procedure is performed, our eye care professionals will conduct a detailed examination to determine your candidacy. Based on the results of those tests, your doctor will recommend the vision correction option best suited for you.
For those looking to reduce their dependence on glasses and contacts but who are not good LASIK candidates, PRK surgery may be an option. Learn more.
