Diagnostic and Treatment Technology
Durrie Vision houses the most advanced diagnostic technology available on the market. Why is this important? Determining your candidacy for any laser vision correction procedure is a critical step as excellent candidates are much more likely to have excellent outcomes and poor candidates are more likely to have poor outcomes.
The Advanced Ocular Analysis is a state of the art eye exam that utilizes many different technologies to render 3D high definition images of your eye functionality as well as your current and future potential vision quality. The results of your exam are digitally integrated into your electronic medical record at Durrie Vision and allow our surgeons to monitor changes in eye health at each exam.
Anterior Segment (Optical Coherence Technology) OCT – A device that takes a digital image of the front of the eye and crystalline lens. These images aid in evaluating the tear film, eyelids, cornea and early cataract formation.
Dilation – Topical medication drops enlarge the pupil so that a full view of the natural lens and retina can be seen and a cycloplegic refraction, which gives a more accurate reading of the refractive error, can be performed.
Fundus Camera – This device takes a digital image of the retina to ensure the health of the inside of the eye.
HD Analyzer – Using simple light rays, this technology provides a wealth of data about the quality of your vision. This unique device is the first of its kind in that it allows for objective measurement of many of the aspects of vision not able to be captured by traditional visual acuity testing. At the same time, this information may be critical for making the best choices for your Lifetime Vision Plan.
Pentacam – This device digitally maps the surface of the cornea and it’s underlying layers to provide indispensable information and precisely image the cornea in consideration of refractive surgery. At the same time, information about the changes in the natural lens of your eye can be captured and displayed with high definition. The pentacam is also one of the few technologies available that provides a multiplicity of corneal maps.
Optical Coherence Technology (OTC) – This technology has revolutionized all aspects of ophthalmology. With resolution millions of times more precise than CT or MRI, the internal structure of your eye can be imaged with the capability of seeing individual cells and tissue layers. This allows us to monitor for potential vision issues that even a microscope could not see. Many aspects of your overall bodily health and nutrition are reflected in the eye and able to be evaluated simultaneously with this modern test. During your Advanced Ocular Analysis we are looking at more than just your eyes!
Specular Microscopy – This is a noninvasive photographic technique that allows visualization and analysis of the corneal endothelium, a layer of the cornea vital for maintaining long term visual clarity and corneal health. Using computer-assisted morphometry, modern specular microscopes analyze the size, shape and population of the endothelial cells of the cornea. Information about these cells is important for surgical (or non-surgical) decisions that are consistent with your Lifetime Vision Plan.
How does Durrie Vision choose its laser platforms? The answer is simple; we choose the lasers with the best visual outcomes. And since Durrie Vision is involved in the comparative research, we have the data to prove it.
Always at the forefront of refractive surgery technology, Dr. Daniel Durrie has been an investigator and involved with the research of every excimer laser since their introduction in 1989. As investigators, Dr. Durrie, Dr. Stahl and Dr. Brinton have the unique perspective to be able to test and compare diagnostic and treatment technology in clinical research trials to ultimately provide you with the best visual outcomes.
Wavefront-Guided, Wavefront-Optimized or Custom LASIK?
These are terms referring to technologies that are often used in conjunction with the lasers used in LASIK. All treatments at Durrie Vision are “customized” to each patient, and the doctors determine the best technologies and treatment plan based on the results of your Advanced Ocular Analysis.
- Treats nearsightedness, farsightedness and astigmatism, plus measures and treats higher order aberrations.
- A map is made by measuring thousands of unique points of a patient’s vision. This measures distortions that glasses and contacts do not correct. A wavefront-guided treatment has the possibility of reducing halo and glare in some patients and may sharpen vision beyond what glasses and contacts were able to provide.
- Creates a treatment pattern that maintains and potentially improves the cornea’s natural curve. This helps produce crisp, sharp vision with the possibility of less nighttime halo and glare after surgery.
Our Laser Platforms
Traditional LASIK is performed by first creating a flap in the cornea with a microkeratome blade. This corneal flap is then reflected back, and a cool beam excimer laser reshapes the cornea to treat nearsightedness, farsightedness and astigmatism. The protective corneal flap is then re-positioned over the treated area where it naturally bonds with no need for stitches.
The most advanced LASIK procedure available today uses a bladeless laser platform incorporating two advanced lasers. SBK- (Sub-Bowman’s Keratomileusis) Advanced LASIK uses a femtosecond laser to create a custom, thin corneal flap prior to the reshaping of the cornea by the excimer laser. This advanced procedure is performed by the most progressive refractive surgeons and allows for more consistent flap thickness, safer flap creation, less inflammation, faster visual recovery and better long term visual outcomes.
Femtosecond Laser Technology
The femtosecond laser replaces the blade commonly used for corneal flap creation making the procedure safer and more precise. The femtosecond laser delivers micron-level accuracy that is critical for successful visual outcomes. We have two femtosecond lasers at Durrie Vision.
The Wavelight FS200 Femtosecond Laser
This laser is designed for precise custom flap creation ensuring safe, accurate and customized procedures at high speed. This laser creates the corneal flap for blade-free (SBK) LASIK by separating the natural layers of the cornea through the creation of microscopic gas bubbles in rapid succession.
The IntraLase IFS Femtosecond Laser
This laser also creates the custom corneal flap for blade-free (SBK) LASIK by separating the natural layers of the cornea with the creation of a rapid succession of microscopic bubbles. IntraLase improves the precision and visual results of LASIK. There are subtle differences between the two lasers, and the surgeon recommends one over the other based on your Advanced Ocular Analysis and Lifetime Vision Plan.
Advantages to the femtosecond laser:
- It allows the surgeon to customize the corneal flap to each individual patient.
- It is computer controlled, delivering micron-level accuracy and improved safety.
- It allows the surgeon to treat a wider range of prescriptions because the depth of the flap can be customized.
- Flap dimensions are accurate and programmable.
- It provides faster visual recovery.
Increasingly, successful LASIK procedures have one thing in common — they use a femtosecond laser to create the corneal flap.
Excimer Laser Technology
Although all technologies are integral to providing a good refractive outcome, the excimer laser could be described as the “crux” of the process when providing SBK-LASIK. Durrie Vision has two excimer lasers that are used to reduce and/or eliminate your refractive error by reshaping the cornea.
The Wavelight EX500 Excimer Laser with PerfectPulse technology is currently the fastest excimer laser operating at 500Hz (laser pulses per second). With a powerful multidimensional eye tracker synchronized at 500Hz, the EX500 offers exceptional precision and safety. The EX500 allows our surgeons to customize your treatment in multiple ways to enhance your visual outcomes and patient experience.
The VISX STAR S4IR Excimer Laser uses our advanced diagnostic technology to measure your eye’s “blueprint” before surgery and allows for a custom wavefront-guided laser vision correction procedure. This excimer laser platform reshapes the cornea by creating a more natural, optically improved post-surgical outcome.
Laser Lens Technology for Cataract and Refractive Lens Exchange
Durrie Vision is proud to offer you a revolutionary advance in laser technology that has created a safer, more precise lens replacement surgery. The LenSx Laser automates the most challenging steps in the traditional cataract or lens replacement procedure, providing a precision based solution customized for your eyes. This bladeless, computer-controlled laser uses a range of highly advanced technologies to first capture incredibly precise, high resolution images and measurements of your eyes. These images, along with the measurements and data they provide, are then used to plan and perform your surgery to exacting specifications not easily attainable with traditional surgery.
Wavetec ORA Technology is a revolutionary technology to optimize visual outcomes for cataract and lens replacement procedures. ORA wavefront technology uses advanced optical physics to provide intraoperative measurements of your eye. This unique technology in the only one available that can assess the optical state of the eye during a surgery, providing the most up to date information to your surgeon when it can be needed most to guide the surgeon’s decision making and optimize your visual outcomes.
