OVERVIEW OF THE PARAGON CRT® CONTACT LENS DESIGN & FITTING GUIDE On June 13, 2002 Paragon Vision Sciences received FDA approval for overnight Corneal Refractive Therapy using Paragon CRT® Contact Lenses. The approval includes up to -6.00D myopia with or without -1.75D astigmatism. The FDA does not have an age restriction when prescribing Paragon CRT® Contact Lenses. Corneal reshaping of the epithelium, which is 50 microns thick is accomplished by a combination of compression and redistribution of fluids within the epithelial cells. The temporary effect is reversible with the cessation of lens wear.
1. BASE CURVE/TREATMENT CURVE
2. RETURN ZONE & RETURN ZONE DEPTH
The central Optic Zone of Paragon CRT® is fixed at 6.0mm and the design contains the Base Curve or Treatment Curve. The Base Curve/Treatment Curve is calculated to be flatter than the underlying corneal radius in order to reduce myopia and should be centered over the pupil.
Key elements of successful Corneal Refractive Therapy are centration and central applanation. The Return Zone Depth (RZD) is the primary parameter used to change the overall sagittal depth of the Paragon CRT® Contact Lens. Paragon’s Proximity Control Technology® allows for precise control of sagittal depth by manipulating the RZD. The RZD is variable in 25-micron increments.
Manipulation of the Base Curve/Treatment Curve is not used for fit adjustment purposes. The Base Curve is not a “fitting curve”; it is the “treatment curve” to help reduce or eliminate the myopic prescription. When making lens centration adjustments, do not change the Base Curve. Always use the RZD, LZA, or a combination of both.
3. LANDING ZONE & LANDING ZONE ANGLE
Base Curve/ Treatment Curve
The peripheral Landing Zone is a flat surface with a radius of infinity. Through fluorescein observation, the prescriber selects the appropriate Landing Zone Angle (LZA) for the correct edge lift. Changing the LZA by 1° affects the overall sagittal depth by 15 microns. Flattening the edge lift or decreasing the LZA by 1° decreases the overall sagittal depth by 15 microns.

PARAGON CRT® CONTACT LENS SELECTOR SLIDE RULE The parameters of the initial diagnostic lens are calculated by using the Paragon CRT® Contact Lens Selector Slide Rule. The Slide Rule is included with your Diagnostic Dispensing System or Technical Kit. The only necessary data are the patient’s flat “K” Reading and their Manifest Refraction Sphere (MRS). An electronic version of the slide rule is available to download at paragonvision.com/ecp Patient Ks & Rx Example: 42.00/42.25D, Flat “K” Reading = 42.00D -3.75-0.25x180, MRS =-3.75 When using the Lens Selector Slide Rule, follow these simple steps:
1
2
Slide the tab until the arrow appears pointing either up or down at the correct Flat “K”.
Find the MRS to the right of the window.
2 1
3
Locate the recommended initial diagnostic Paragon CRT® Contact Lens number and lens parameters in the window immediately next to the MRS.
4
Prior to insertion of the lens, a topical anesthetic is optional to reduce reflex tearing and maximize patient comfort during the fitting process.
5
Perform an Refraction Over the Lens (ROL) to confirm the accuracy of selected BC. The ROL should be Plano to +0.50D for optimal results.
96. 88 - 550 -33 BC = 8.8 RZD = .550 LZA = °33
Example: 3
LENS SELECTOR The Paragon CRT® Contact Lens Selector Slide Rule algorithm is designed to create a -0.50D tear layer over-correction. All lenses in the Diagnostic Dispensing System are +0.50D in power to compensate. If the ROL yields a “minus power over-refraction”, the BC is too steep and should be flattened in 0.10mm steps for every -0.50D over-refraction. Conversely, if the ROL yields a “plus power over-refraction”, the BC is too flat and should be steepened in 0.10mm steps for every +0.50D over-refraction.
4
RETURN ZONE & RETURN ZONE DEPTH The appropriate Return Zone has the “shallowest” Return Zone Depth that provides overall lens centration and results in a 3-4mm area of central applanation, as observed by fluorescein pattern evaluation. (Figure 1) However, if a greater Return Zone Depth is necessary to achieve centration, a smaller area of central applanation may be initially acceptable. Once a central area of treatment has been established, the sagittal depth can be adjusted during followup. (Figure 2) • An RZD that is too shallow may exhibit apical touch but have insufficient tear layer in the periphery and may decenter upwards. • An RZD that is too great will not demonstrate the desired 3-4mm area of central applanation. In both cases, the correction is to change the overall sagittal depth (either shallower or deeper) by adjusting the the Return Zone Depth. See below for RZD problem solving techniques as it relates to overall sagittal depth. Remember: • The RZD can be customized in meridional depth differences with an RZD1 and RZD2. • Base Curve changes should not be used to alter or change the sagittal depth.

RETURN ZONE DEPTH IN RELATION TO OVERALL SAGITTAL DEPTH The most critical fitting goal is centration. Once a Paragon CRT® Contact Lens is well-centered, adjustments to the RZD may be required to achieve the desired 3-4mm zone of applanation. Below are three different RZD’s on the same cornea. In each case, the only varied parameter is a 25-micron RZD adjustment.
.575 RZD
Observation 1
Excessive clearance; bubble in the RZD. The depth of the RZD is too great. The Base Curve (or Treatment Curve) may not applanate the central cornea with the optimal 3-4mm treatment zone. Solution: Reduce the RZD 25 microns (Example: move from 575 to 550)
.550 RZD
Observation 2
While the reduction of the RZD by 25 microns resulted in the loss of the bubble, there is still insufficient applanation to the center of the cornea. A further reduction in sagittal depth is required. Solution: Reduce the RZD 25 microns. (Example: move from 550 to 525) Note: If the reduction in the RZD by 25 micron results in a decentered lens, return to the previous RZD. 5
.525 RZD
LANDING ZONE & LANDING ZONE ANGLE
CORRECT LANDING ZONE ANGLES PROVIDE APPROPRIATE EDGE LIFT
The primary function of the Landing Zone is to provide a safe, tangential landing on the peripheral cornea. The Landing Zone Angle (LZA) is adjustable by degrees to create the appropriate edge lift. If the LZA suggested by the Slide Rule demonstrates edge lift that is not optimal, the angle of the Landing Zone is adjustable in 1° degree steps.
- - - - - - - -31 -32 -33
-33° LZA
-34
-35
In this example, the appropriate LZA provides sufficient edge lift.
The LZA is a flat surface with a radius of curvature, and can only meet the curved peripheral corneal surface tangentially.
- - - - - - - -31 -32 -33
-32° LZA
-35
-34
In this example, the -32° LZA is creating excessive edge lift. An increase in the LZA will reduce the edge lift. (Example: Change LZA from -32° to -33°)
33° LZA
- - - - - - - -31
LZA FACTS
-34° LZA
Landing Zone Angles are available in varying degrees to provide appropriate and adequate edge lift.
-32 -33 -35
-34
In this example, the -34° LZA is not creating adequate edge lift. A decrease in the LZA will increase the edge lift. (Example: Change LZA from -34° to -33°)
LZAs can be ordered with custom meridians separated up to 2 degrees to align to the flat and steep meridian of an eye that displays limbus-to-limbus or extensive corneal cylinder, ex: LZA1=-33, LZA2=-34. These custom parameters constitute a Paragon CRT Dual Axis® lens.
DIAMETER CHANGES Patients with larger HVIDs may need an increased diameter for the lens. For every 0.5mm change in diameter, the LZA must be modified by 1°. The LZA this modification keeps the edge lift relationship to the cornea the same.
The most common LZAs are -32°, -33°, and -34°.
SAGITTAL DEPTH CHANGES Any increase in the number value of either the RZD or the LZA will increase overall sagittal depth. Conversly, any decrease in the number value of either the RZD or the LZA will decrease overall sagittal depth.
For example, if the diameter is increased from 10.5mm to 11.0mm, increase the LZA by 1°. If the diameter is decreased from 10.5mm to 10.0mm, decrease the LZA by 1°. 6
SOLVING PARAGON CRT® CONTACT LENS DECENTRATION PROBLEMS Fluorescein Pattern
Goal: Bull’s Eye Fluorescein Pattern In the fluorescein pattern of a properly fit Paragon CRT® Contact Lens the Base Curve/Treatment Curve should be well-centered over the pupil and exhibit a 3-4mm area of central touch/applanation. A Plano/+0.50D ROL (Refraction Over Lens) will provide the patient with maximum treatment results.
Observation: Superior / Superior Lateral Decentration Lenses that are too shallow in overall sagittal depth may decenter superiorly / superiorly laterally. An increase in overall sagittal depth is necessary. Solution: Increase Sagittal Depth 1. Increase RZD one step (25 microns) 2. Increase LZA one degree (~15 microns) 3. Increase Overall Diameter
Observation: Inferior Decentration Lenses that are too deep may decenter inferiorly. Solution: Decrease Sagittal Depth 1. Decrease LZA one degree (~15 microns) 2. Maintain the LZA and decrease the RZD 25 microns
Observation: Pure Lateral Decentration Lenses that are too shallow in overall sagittal depth may decenter laterally. An increase in diameter size by 0.5mm is necessary. Solution: 1. Increase LZA (ex: -33 --> -34) when increasing diameter size (from 10.5mm to 11.0mm) to maintain same edge lift relationship to the peripheral cornea. 7
Topography Pattern
RECOMMENDED FOLLOW-UP SCHEDULE On the first morning follow-up visit, the patient should arrive wearing their Paragon CRT® Contact Lenses.
WHAT TO EXPECT AFTER THE FIRST MORNING FOLLOW-UP
STEP 1 With the lenses on: • Check visual acuity • Perform a Refraction Over Lens (ROL) • Result should be “Plano to +0.50D” • Perform a slit lamp evaluation with white light and fluorescein: • Confirm: • Corneal integrity • Appropriate edge lift • Lens centration
The patient’s treatment will not likely last throughout their waking hours during the first day following overnight treatment. Vision may be managed with Paragon CRT® Contact Lenses or soft disposable lenses during the day and throughout the 7-14 day treatment period. The patient should see clearly while wearing their Paragon CRT® Contact Lenses, provided the Base Curve and Refraction Over Lens are correct. At the end of the treatment period, the patient should enjoy excellent visual acuity for all or most of their waking hours.
STEP 2 Remove the Paragon CRT® Contact Lenses: • Check visual acuity • Perform a manifest refraction to determine the amount of treatment achieved during the first night of therapy.

CONSUMER MARKETING TIPS
ORDERING BROCHURES We make it easy to order consumer brochures, and we can customize brochures with your practice information.
KEEP IT SIMPLE Implementing a Paragon CRT® Contact Lens marketing campaign doesn’t have to cost a fortune, involve an outside marketing firm, or consume your valuable time. Paragon Vision Sciences strongly recommends taking action to alert your existing patients about the innovative technology offered in your practice. Here are some quick, easy, and inexpensive ways to begin your marketing campaign.
START WITH CONSUMER BROCHURES After more than a decade of post FDA clearance, the “teen and tween” markets have evolved as one of the leading growth segments for Paragon CRT® Contact Lenses. Children and adolescents between the ages of “8-to-18” are great candidates for Paragon CRT® Contact Lenses because: • There is no age restriction with Paragon CRT® Contact Lenses • They may be too young for LASIK • They have active, sport related lifestyles • Glasses or daytime contacts may interfere with some activities
70 %
CONSUMER WEBSITE Having an online presence is more important today than ever before. But keeping your website content up to date and relevant to the services offered in your practice is even more crucial to achieving practice growth. Paragon Vision Sciences makes it easy to market Paragon CRT® Contact Lenses on your website, or on a variety of social media outlets you may be using. Linking directly from your practice website to paragonvision.com ensures that your practice is providing existing and potential new patients with current information on Paragon CRT® Contact Lenses.
MORE THAN 70% OF PARAGON CRT® CONTACT LENS PATIENTS ARE BETWEEN THE AGES OF 8-TO-18.1
Paragon Vision Sciences provides your office with educational consumer brochures to explain what orthokeratology with Paragon CRT® Contact Lenses is and how a patient’s quality of life can be improved.
You can also follow us on Facebook, for example, and share status updates on your own practice Facebook page.
It may sound “too simple”, but by placing the Paragon CRT® Contact Lens consumer brochures at your checkin counter and having your receptionist offer the patient a brochure which explains “the innovative technology offered in the practice”, you’re marketing to someone who you’ve already won over. The patient is in your office and ready for an eye exam by the doctor they trust.

USE YOUR STAFF TO IDENTIFY CANDIDATES
BOOKS
Behind every successful practice is a strong and focused staff! A well-trained staff is the key to having a successful practice. Your staff comes into contact with your patients before you see them in the chair, and in your patient’s eyes, your staff is an extension of the services they expect from you. Use your staff to help you identify potential Paragon CRT® Contact Lens candidates during the workup process, and reward them when you develop a new Paragon CRT® Contact Lens patient in the practice. Rewards can be as simple as gift certificates or a nominal bonus in their paycheck. Without the support of your staff, integrating Paragon CRT® Contact Lenses into your practice may be a challenge.
Paragon Vision Sciences has supported the distribution of one of the best, well-written books on nearsightedness, “My Children Are Nearsighted Too”, by Nicholas Despotidis, O.D. “Dr. D,” as he is commonly referred to by his patients and colleagues, takes the reader through personal experiences, frustrations and ultimately the moments of triumph that Ortho-K provided his patients. Dr. D talks about how his two sons have successfully worn ortho-k lenses for years and this book can be a useful tool to have in your waiting room. To place your order, visit: paragonvision.com.
Educate your staff on what a good Paragon CRT® Contact Lens candidate looks like: • Paragon CRT® Contact Lenses are FDA approved up to -6.00D, with or without 1.75D astigmatism, and unlike LASIK, there is no age restriction • Between the ages of 8-to-18 • Has an active or athletic lifestyle and currently wears spectacles or daytime soft contact lenses that interfere with their daily activities • Adults who suffer from uncomfortable daytime soft contact lens wear due to dryness
Available in English, Spanish, & Chinese
• Adults who are apprehensive about having eye surgery or afraid of a bad surgical result, the reversibility of Paragon CRT® contact lenses is attractive • Patients that are unsuitable for LASIK because of age, thin corneas, etc.
