The mission of Clear Advantage is to provide our patients with the most technologically advanced vision correction options in New England. Our highly experienced surgical staff is dedicated to educating patients on a variety of refractive procedures in a personalized and comfortable manner.
Centrally located in Portsmouth, NH, and just one hour from Boston, MA, Manchester, NH and Portland, ME, Clear Advantage is easily accessible. Located just two buildings away from Portsmouth Regional Hospital, our location at 155 Borthwick Avenue is in the heart of the seacoast medical community and home to some of the top medical professionals in the world.
Clear vision is achieved when light rays are focused and processed by the many parts of the eye. Light travels from an object and enters the eyes through the cornea, which is the transparent outer covering at the front of the eye. The cornea helps focus, or “refract” the light, which then passes into the interior of the eye through the pupil. The iris, or color portion of your eye, opens and closes – like a camera shutter – making the pupil larger at night to allow more light in, and smaller in sunlight to decrease brightness. Next, the light passes through the lens of the eye, which changes shape to focus the light onto the retina at the back of the eye.
When looking at nearby objects, more focusing strength is required in order for the image to remain clear. The lens increases focusing strength by becoming more convex in shape, a process called accommodation. All of the eye’s parts must be correctly tuned for images to be clearly focused on the retina. The eye’s shape is also important in determining clear vision. If the eye is either too long (myopic), or too short (hyperopic), light rays are not focused properly on the retina. If the eye is unevenly shaped (astigmatism), images will also be blurry.
Once the surgeon has determined that you a candidate for laser vision correction, you can often schedule your procedure within the same week! Surgical appointments run every half hour from 10:00 a.m. to 6:00 p.m. on Thursdays, and 9:00 a.m. to 4:00 p.m. one Friday per month.
If you schedule surgery:
FEMTOSECOND BLADEFREE LASER: Use of the DaVinci femtosecond laser during vision correction increases safety and precision. A femtosecond is a quadrillionth of a second, and this is the speed of each DaVinci laser pulse. Rather than having a traditionally used blade cut the corneal flap, the DaVinci uses a fast, pulsed laser to create many microscopic bubbles just below the corneal surface. The laser moves back and forth over the designated treatment area on the eye, and creates a round, shallow area of these tiny bubbles. Then the surgeon uses a special instrument to gently lift that tissue and fold it back out of the way.

PRK: If the cornea is too thin for LASIK or if you have undergone LASIK previously and have a thinner residual cornea, then PRK may be an option presented during your evaluation. During PRK, the cornea’s epithelial (outer) layer is removed using a special solution to expose the area, and no flap is created. For both PRK and LASIK, the excimer laser then sculpts the stromal layer of the cornea to correct your refractive error. Though PRK recovery takes a bit longer than recovery from methods utilizing flap creation, PRK is still commonly used worldwide.
During the evaluation, our doctor will calculate the treatment option that will offer you the best visual results. This is determined by your prescription, the thickness of your cornea, your astigmatism, and the amount of aberrations recorded during your evaluation. We are proud to offer several different treatment options:
TRADITIONAL LASIK (Laser Assisted In-Situ Keratomileusis)
LASIK combines the proven techniques of both corneal flap and excimer laser surgery, resulting in dramatic results and rapid visual recovery. LASIK is effective for correcting most cases of nearsightedness, farsightedness and astigmatism.
ADVANCED LASIK WITH THE MEL80 SYSTEM BY ZEISS
Clear Advantage is the first and only practice in New England offering advanced LASIK treatments using the ultra-precise Zeiss Mel80 system. As of August 2006, this was the latest laser to be approved by the Food and Drug Administration (FDA). The MEL80™ is a fifth generation laser and one of the fastest lasers in the world.
The speed of the Mel80 shortens the treatment time, and thus shortens exposure time which helps enable a faster visual recovery. The MEL80™ also has a new, ultrafast eye tracker. As a result, this tool for all-laser LASIK is greatly beneficial for our patients, and we are proud to offer such cutting-edge technology.
ZYOPTIX CUSTOMIZED LASIK BY BAUSCH & LOMB
The Zyoptix system utilizes Advanced Control Eyetracking (ACE) which allows the laser to compensate for eye movements during the procedure, thus adding an important level of assurance. Until mid-2009, no eye tracker had been able to adjust for subtle rotations of the eye that occur during the laser treatment. Using the latest technology, the laser corrects refractive errors by utilizing its small beam profile to flatten the cornea centrally and then “polishes” the periphery, or transition zone, to produce an extremely smooth cornea. It is capable of performing wavefront-guided and traditional LASIK procedures. It is also ideal for patients with large optical zones and/or mixed treatment requirements.
Our practice offers only the most advanced FDA-approved procedures. We offer multiple laser platforms to ensure the safest and most accurate procedure possible regardless of your astigmatism or nearsighted or farsighted prescription.
The first step to learning about vision correction options and what option may be best for you, is to schedule a comprehensive evaluation with our office.
Because contact lenses alter the shape of the cornea, preventing an accurate measurement, it is important that you do not wear soft contact lenses for five days prior to surgery; toric lenses, or astigmatism correcting lenses, should not be worn for 10 days before surgery; and hard contact lenses should not be worn for eight weeks prior to the evaluation AND prior to surgery. For example, if you have an evaluation but do not plan to have surgery for a few months, it is safe to put your contact lenses back in after the evaluation, as long as they are removed again before surgery for the same amount of time. If you wear toric or hard lenses, we also offer mini-LASIK evaluations. Although a full evaluation will still be required, a 20 minute mini-evaluation will allow us to take preliminary measurements to better determine the likeliness of your candidacy for vision correction. Call our office for details.
Unlike other LASIK practices, we don’t have a “sliding scale” of costs, adding costs to your procedure for follow-ups, dry-eye treatments or enhancements. In fact, we offer many discounts to make your lifelong vision change more affordable. Pricing is based on your procedure, and that is based on the prescription, pupil size, corneal thickness and aberrations. Until we see you for your evaluation, we don’t know which procedure would offer you the best visual results, but are happy to explain the general characteristics of each.
Insurance does not generally “cover” the cost of corrective vision services, but we are in contract with most of the major vision and medical plans to offer discounts. We currently offer discounts through:
Interest-free plans are available for 6, 12, 18 and 24 months; extended plans are available up to 60 months (with interest). For more information go to www.CareCredit.com. Applying is easy, and can be done online for instant approval!
Save 15 percent if two or more family members have corrective vision services within one year. Save an additional 5 percent if two or more have surgery the same day.
We offer discounts for individuals working in the medical field, and for those actively serving in the armed forces.
Does your organization employ 10+ people? Ask your benefit department to sign up for our FREE Corporate Vision Program. The Corporate Vision Program includes a significant discount on LASIK vision correction not available to the general public, and participation costs your company NOTHING! Best of all, the program is available to all employees – regardless of their insurance benefits or whether they are full-time, part-time or volunteer. Contact our office for more details or to sign up.
Our surgeon, N. Timothy Peters, M.D., has performed over 21,000 successful LASIK procedures. Of these procedures, less than 2 percent required an enhancement. An enhancement is a LASIK re-treatment that is available if the initial LASIK procedure does not correct all of the prescription. Patients with significantly high prescriptions make up the majority of those needing an enhancement to obtain full correction. While most competitors charge an upfront fee for an enhancement “guarantee,” Clear Advantage offers LASIK patients re-treatment at no additional cost. This represents a typical savings of $1,000 per eye. In addition, patients who maintain annual routine eye care with their eye care professional following LASIK qualify for our Lifetime Guarantee. This guarantee provides re-treatment at significantly lower rates than those charged by competing practices. A copy of the guideline will be supplied during your evaluation.
The latest in eye surgery is the Visian Implantable Contact Lens or ICL, which was originally designed for patients who were not candidates for LASIK surgery due to high myopic (nearsighted) prescriptions. But the success of the Visian ICL implant has resulted in an increased interest from candidates who are also considered good choices for LASIK.
The Visian ICL is an Implantable Collamer Lens that works with the eye to correct patients with moderate to severe nearsightedness. Unlike traditional contact lenses that go on the surface of the eye, the Visian ICL is positioned inside the eye between the iris and the natural lens where it stays indefinitely. With a satisfaction rate of over 99 percent many of our patients choose the Visian ICL to get the freedom from their contact lenses and glasses that they’ve always desired. The Visian ICL is the procedure of choice for patients who need and expect higher quality results in performance and safety. In fact, the U.S. Military has embraced the Visian ICL because of the reliable visual clarity it achieves. Much like the recovery with laser vision procedures like LASIK, results are very fast with the Visian ICL.
There have been over a million Visian ICL procedures performed worldwide.
