Refractive Technology at Swagel Wootton Eye Institute Helps Patients See Clearly

March 27th, 2022

At Swagel Wootton Eye Institute, our eye doctors and eye care team want to ensure you receive the very best eye care diagnostic testing, treatment options and procedures available in the Phoenix area. When you come in to receive treatment for nearsightedness, farsightedness, or astigmatism, you can experience our commitment to excellence firsthand through our caring team, our knowledgeable, skilled eye doctors, and our advanced technology.

When you have an eye condition that impacts your vision, it can be challenging just to accomplish everyday activities. It may be even more difficult for those who require high prescriptions for eyeglasses or contact lenses. As these are such common eyesight problems, we offer the most advanced vision correction options, including:

  • LASIK (laser-assisted in situ keratomileuses)
  • PRK (photorefractive keratectomy)
  • Visian ICL (implantable collamer lens)
  • RLE (Refractive Lens Exchange)

Our staff utilizes the latest, cutting-edge diagnostic and treatment technology for each procedure. We encourage you to follow along below to learn more about how you can benefit from our procedures and technology.

LASIK Surgery and PRK Procedure


If you experience nearsightedness, farsightedness, and astigmatism, you may have an irregularly shaped cornea. Often, this interferes with the way your eye interprets light. If the light does not reach the back of your eye properly, or if the light waves disrupt or bend in improper ways, the retina does not receive accurate light information. As a result, the retina transmits incorrect image information to the brain, resulting in blurry, fuzzy, or incomplete images.

LASIK and PRK surgeries focus on reshaping the cornea in order to create a natural, round, curved shape that transmits light properly towards the back of the eye. As a result, you can enjoy significantly improved vision!

Today, with assistance from state-of-the-art technology, our eye doctors in Mesa and Chandler can perform bladeless LASIK or PRK surgery. At Swagel Wootton Eye Institute, we use the most advanced laser technology available to perform your surgery, the Wavelight® Laser Suite. We also use state-of-the-art measuring and mapping technology to ensure your candidacy and your treatment plan.

At Swagel Wootton Eye Institute, we specialize in vision correction surgery and will walk you through all your options.

Our Advanced LASIK Technology

Our LASIK technology allows our eyecare team and eye doctors to perform your LASIK surgery with the utmost precision and safety. With the Wavelight® Laser Suite, we can use two types of lasers to accomplish the procedure, the femtosecond laser and the excimer laser. As the femtosecond laser uses ultrasound waves, we can use this laser to make a very thin, accurate, and even cut into the cornea. In this way, we can create a flap to reveal the cornea. One of the main advantages of this type of laser is that it can make cuts at a precise angle and curve, allowing the eye doctor to create a flap that follows the curvature of your eye.

The second type of laser is the excimer laser. The surgeon uses this ultraviolet laser to break up the cornea and remove the tissue from precisely indicated sections of the eye. Overall, the accuracy and efficiency offered by the Wavelight® Laser Suite allows for:

  • Personalized surgeries
  • Improved vision outcomes
  • Greater overall safety
  • Less operative and healing period risks
  • Faster healing times
  • Quick and efficient procedures

Our Advanced PRK Technology

When our Swagel Wootton eye doctors perform the PRK procedure, we also use the Wavelight® Laser Suite for bladeless surgery. Unlike LASIK surgery, which uses two types of lasers, in PRK surgery we only use the excimer laser; we do not need to create a cut or flap in the side of the cornea in order to access the cornea. Rather, we use the ultraviolet laser to remove the outermost layer of the cornea carefully and quickly. Then, the surgeon uses the laser to reshape the cornea by removing tissue from specific parts of the eye. This advanced laser allows us to perform incredibly precise tissue removal, according to your specific eye condition. You can expect similar benefits from the Wavelight® lasers as with LASIK, namely, the precise movements of lasers allowing for efficient and tailored PRK surgery, improved vision outcomes, increased safety, and quick healing times.

LASIK and PRK Evaluation

At Swagel Wootton Eye Institute, we ensure that you receive the best treatment for your specific vision correction by going through a careful evaluation procedure. Through the most advanced LASIK and PRK testing and candidacy determination technology, the CONTOURA® Vision and Vario Diagnostic Device, we can confirm if you are eligible for either LASIK or PRK with a great degree of precision.

Advanced CONTOURA® Evaluation

We use the CONTOURA® Vision testing to determine candidacy and to provide a precise map of your eye for LASIK or PRK surgery. Rather than relying on a 2D map of the surface of your eye, the CONTOURA® gives us a 3D figure of your eye mapping thousands of topographical points. In this way, we can view all the unique and detailed characteristics of your eye including steep slopes, moderate curves, flat areas, abrasions, irregularities, inconsistencies, and many other features.

CONTOURA® and Refractive Surgery

One of the great advantages of using CONTOURA® Vision testing is that the detailed map can upload onto the Wavelight® Laser Suite which we use for your LASIK or PRK surgery. It allows us to customize your surgery to the exact shape and characteristics of your eye. In this way, we significantly improve vision outcomes for our patients.

Vario Measurements

The Vario device allows us to take detailed and accurate measurements of the surface of your eye, such as the thickness of the cornea, and upload it into the CONTOURA® digital platform. Taking your measurements is an incredibly quick procedure that does not involve touching your eye physically, rather it is performed with rapid scanning technology.

Visian ICL Surgery


If you suffer from moderate to severe nearsightedness or astigmatism, you may be considering the Implantable Collamer Lens as an alternative to high prescription glasses or contact lenses. At Swagel Wootton Eye Institute, we are proud to offer state-of-the-art Visian ICL surgery to all our patients in the greater Phoenix area as an effective, stable, and safe procedure to correct vision problems.

Our Advanced Visian ICL Technology

When we perform the Visian ICL procedure, we create a tiny slice in the cornea and place Visian ICLs into the eye, right ahead of the natural lens in the eye. A Visian ICL is a special type of lens that corrects refractive issues. It is a collagen material lens that is compatible with living tissue. In this way, it is readily accepted by the eye and poses a low risk of rejection. Furthermore, we select the advanced Visian ICL because:

  • Patients realize improved eyesight almost immediately after surgery.
  • It provides clear, distinct, and vibrant vision.
  • It is a quick and efficient procedure, only taking a maximum of 15 minutes.
  • It offers UV protection.
  • It is undetectable and invisible.
  • It is permanent, although the surgery is completely reversible if necessary.
  • It has a high satisfaction rate.

Visian ICL Evaluation

Our Swagel Wootton Eye Institute team determines if you qualify for this procedure by using our advanced measurement and testing technology, the Pentacam and A-Scan Ocular Ultrasound Device. The Pentacam provides us with an accurate measurement of certain features of your eye, such as the cornea and anterior chamber. Moreover, the A-Scan allows us to determine your specific eye condition and take further measurements such as the length of your eye. When we analyze the results of our scans, we can verify the correct ICL lenses for your specific eye measurements.

RLE Procedure


When you experience vision issues, it can also be frustrating to navigate the different treatments available with traditional evaluation and testing methods. Fortunately, with the advanced diagnostic and treatment technology at Swagel Wootton Eye Institute, we can determine with high accuracy the best type of treatment for your eyes. If you are not eligible for LASIK, PRK, or Visian ICL, you may qualify for RLE or Refractive Lens Exchange, also known as CLE, or Clear Lens Exchange It is an effective treatment for nearsightedness, farsightedness, and preventative measures against cataract formation.

During the RLE procedure, we remove the natural lens of the eye with an ultrasound probe and replace it with an artificial intraocular lens (IOL). However, unlike cataract surgery, we do not remove a lens that is cloudy due to cataracts. The lens is actually clear in this case.

Our CLE Technology

Our advanced RLE technology makes it possible to improve your eyesight to a great degree when you suffer from moderate to extreme prescriptions or presbyopia. In particular, we use the most advanced IOLs available, specifically, Alcon’s PanOptix lens, Vivity lens, and RxSight Light adjustable lens:

  • PanOptix Lens: A trifocal lens that allows you to focus on many distances naturally. It also provides clear, distinctive, and vivid images while giving the added benefit of less glare from bright lights.
  • Vivity Lens: An IOL that lets you see an extended, seamless range of vision. With this lens, you can see far, mid, or near-distance images clearly and distinctly.
  • RxSight Light Adjustable Lens: This advanced lens allows the eye doctor to adjust the power and precision of your eyesight after surgery.

LenSx Laser-Assisted Surgery

When we are performing the RLE procedure, the eye doctor uses the LenSX Laser-Assisted Surgery to ensure an accurate, safe surgery and quick healing time. The eye doctor uses this special, advanced laser tool in order to create the primary, precise incision in the cornea, to access the natural lens of the eye. We also perform the second step of breaking apart and removing the natural lens with this tool.

Intraoperative Wavefront Aberrometry

During the RLE procedure, we take advantage of an advanced machine, the Intraoperative Wavefront Aberrometry, to determine which lenses are perfect for you. After removing the natural lens from the eye, this technology makes it possible to test your eye’s refractive power or the way your eye transmits light to the retina. From this evaluation, we can determine the exact IOL you need to process light properly and correct your eyesight.
