The lens is indicated for the visual correction of various ocular conditions including keratoconus, pellucid marginal degeneration, corneal transplants, post refractive surgery and/or any irregular cornea conditions. Lens Design The Flexlens ARC design utilizes a standard back surface fitting curve with an enhanced center thickness to stabilize the correction over an aberrated cornea. If residual astigmatism is detected through the over-refraction a toric design is needed. Cylinder powers ranging from -0.75 up to a -10.00 are available with prism ballast to reduce lens rotation. There is a laser mark (V) at 6 o’clock to mark the location of the prism ballast. A range of base curves and center thicknesses can be manipulated to successfully fit a wide patient base. With no need to worry about peripheral curves or any other parameter that may complicate the fit, the Flexlens ARC is easy to fit, thus reducing chair time.

Starting with the position evaluation of the lens, look for a well centered alignment with no more than 2mm of movement. 2. Centrally the lens should display slight central touch with no air bubbles or folds. 3. Let lens settle for 10 minutes before performing rotation, edge and acuity evaluation. 4. Check for lens rotation. Any rotation over 10 degrees requires next steeper base curve. 5. Evaluate the edge in complete 360 degree circle by checking all four gazes (Up, Down, Right, Left) 6. Perform sphere-cylinder over-refraction and compare to best achievable acuity of patient. (should be at least equal) 7. All evaluation information should be given to an X-Cel consultant for final lens order.

Indications Examples include, but are not limited to: irregular astigmatism created by keratoconus, trauma, or post/penetrating keratoplasty. The lens is for patients with moderate to advanced keratoconus and is ideal for those: • Who cannot adapt to a rigid lens material • With monocular keratoconus who wish to wear a soft lens in the fellow eye • Who experience decentered optics with a rigid lens material Other patients who may benefit from the increased central thickness and rigidity of the Tri-Curve Keratoconus Lens for vision correction include those with: • Pellucid marginal degeneration • Refractive surgery The Flexlens Tri-Curve Keratoconus lens can correct up to 6.00 diopters of irregular astigmatism, but may need a .65 center thickness to do so. Below are cases where the Tri-Curve Keratoconus should be considered: PMD RK RK TRAUMA POST PK CENTRAL NIPPLE CONE CONE LARGE SAGGING CONE 2775 Premiere Parkway, Suite 600 • Duluth, GA 30097 • 800-241-9312 • Fax 800.822.9235 8 FLEXLENS® T RI- C U RVE Lens Design The Flexlens Tri-Curve Keratoconus Lens is based on a tri-curve posterior design. The optical success of the design is based on the standard center thickness that ranges from .45 to .65mm which is often thicker than the keratoconus cornea itself. The design incorporates a flat secondary curve of 1.2mm to 1.8mm flatter, depending on the base curve. A scleral curve with a radius of 2.2mm to 2.8mm flatter, depending on the base curve, is added peripherally to align with the scleral curve of the eye. For those patients who exhibit high degrees of irregular astigmatism, they may be better served with the Flexlens ARC design. Parameter Availability - Available in single, 3, 6 & 12 packs.

If the lens centers well, a simple “push-up” test will verify if the base curve is appropriate for the patient. Place your index finger on the patient’s lower lid margin and manually push the lower lid and evaluate the lens movement. If the decentered lens slowly drops into a centered position, the lens to cornea relationship is appropriate. If the lens remains in a superior decentered position, or if edge stand off is noted as the lens reaches the lower limbus, the base curve relationship is too flat. In this situation, the next steeper base curve/diameter should be evaluated. A steep fitting lens will exhibit resistance to the manual manipulation of the lens with the lower lid. In this situation, the next flatter base curve can be evaluated. Lens Power If the visual acuity is less than expected, an additional over-refraction should be performed. The most accurate results will be obtained after the lens is worn for three to seven days of daily wear, with the lens being worn at least four hours on examination day.

Lens Design The Post Refractive Lens function allows the central optical portion of the lens to be flatter than the mid-periphery. The optical zone has a thickness of approximately .28mm at –1.00D, which provides stable optics over the central cornea. The peripheral lens carrier is as thin as, or thinner than, any standard soft lens to ensure maximum oxygen permeability to the peripheral cornea, limbus and conjunctiva.

Central keratometric readings are of little value in fitting the Post Refractive Lens. A diagnostic set is recommended for most successful fitting of this lens. Select a lens from the diagnostic set with a base curve of 8.7mm and a diameter of 15.0mm. Allow the lens to settle a few minutes before performing the initial evaluation. If the diagnostic lens does not exhibit obvious edge lift, allow the lens to settle an additional 30 minutes. If the lens does exhibit edge lift or decenters in any direction, this indicates a flat fitting relationship and the next steeper base curve should be tried. Push Up Test If the lens centers well, a simple “push-up” test will verify if the base curve is appropriate for the patient. Place your index finger on the patient’s lower lid margin and manually push the lower lens edge up to the lower limbus. Release your finger pressure from the lower lid and evaluate the lens movement. If the decentered lens slowly drops into a centered position, the lens to cornea relationship is appropriate. If the lens remains in a superior decentered position, or if edge stand off is noted as the lens reaches the lower limbus, the base curve relationship is too flat. In this situation, the next steeper base curve/diameter should be evaluated. A steep fitting lens will exhibit resistance to the manual manipulation of the lens with the lower lid. In this situation, the next flatter base curve can be evaluated.

This lens is indicated where centration is difficult to achieve due to an irregular corneal surface. Patients who would benefit from this design could have: • Beginning to advanced keratoconus • Pellucid marginal degeneration • Terrien’s marginal degeneration • Penetrating Keratoplasty • Refractive corneal surgery • Corneal trauma • Corneal surface disease Lens Design The Piggyback Lens incorporates a central circular depression into the anterior surface of the soft lens carrier. The design recesses the GP lens within the soft lens eliminating upper lid dislodgement and maintaining centration of the GP optics over the pupil.

SOFT LENS BASE CURVE The Piggyback Lens fitting criteria is identical to any soft lens, with movement and centration the primary factors. The initial lens selection should be 1.0mm flatter than the patient’s flattest keratometric value (in mm). There should be lens centration with 1.0 to 1.5mm of limbal draping and lens movement should be minimal, 0.25 to 0.50mm in primary position with normal blink. EXAMPLE: “K’s” Flat “K” Diagnostic lens 52.00D @ 180 / 57.00D @ 090 52.00D = 6.49mm 7.5mm Base Curve Recommended lens: 7.5mm Base Curve, 14.5mm Diameter, Plano Power, 10.2mm Anterior Cut-out Diameter Diagnostic fitting of the soft lens is enhanced by inserting a GP lens that is 1.0mm smaller than the recessed cut-out diameter. GP Insert Lens: Take the keratometric reading for the insert lens over the piggyback carrier. For example, if the anterior cut-out is 10.2mm, the largest GP lens diameter would be 9.2mm. This will mimic the final weight and lid to lens interaction, allowing for a better evaluation. NOTE: The soft lens skirt should be inserted first, followed by the GP lens being inserted on top of the soft lens. Lens Evaluation When evaluating the fit of the Piggyback lens, the soft lens should exhibit: 15 • Lens centration with 1.0 to 1.5mm of limbal draping www.xcelcontacts.com FLEXLENS® PIG G YBAC K Push Up Test If the soft lens decenters up, down, left or right, the base curve is most likely too flat and the next steeper base curve should be evaluated. If the soft lens centers well, a simple “push-up” test will verify if the base curve is appropriate for the patient. Place your index finger on the patient’s lower lid margin and manually push the lower lens edge up to the lower limbus. Release your finger pressure from the lower lid and evaluate the lens movement. If the decentered lens slowly drops into a centered position, the lens to cornea relationship is appropriate. If the lens remains in a superior decentered position, or if edge stand off is noted as the lens reaches the lower limbus, the base curve relationship is too flat. In this situation the next steeper base curve/diameter should be evaluated. A steep fitting lens will exhibit resistance to the manual manipulation of the lens with the lower lid. In this situation, the next flatter base curve can be evaluated. Gas Permeable Insert Once the appropriate soft lens has been designed, the GP lens is removed from the central cut-out with a standard GP suction device. Keratometry is performed over the central depression of the soft contact lens and a standard GP lens is designed as if it were being fit onto the cornea. A base curve is selected on “K” or .10mm steeper than the flat “K”. The GP lens diameter should be selected at least 1.0mm smaller than the anterior cut-out boundaries to facilitate lens movement and tear exchange. Ensures centration of the rigid lens over the central cornea maintaining a comfort level similar to a soft lens, allowing freedom of day to day activities without discomfort. 2775 Premiere Parkway, Suite 600 • Duluth, GA 30097 • 800-241-9312 • Fax 800.822.9235 16 FLEXLENS® PIG G YBAC K Troubleshooting Patient Symptoms Objective Findings Possible Cause Plan Incorrect refraction or over-refraction Order new GP lens based on new refraction or over-refraction Base curve too flat Steepen base curve by 0.50D and adjust power Anterior cut-out too large Order new soft lens with smaller anterior cut-out Lens too small Increase soft lens diameter by 0.5mm Lens too loose Steepen soft lens base curve by 0.3mm Bubble between posterior surface of GP and anterior surface of soft lens Incorrect GP base curve Flatten GP base curve by 0.50D and adjust power GP lens too large for anterior cut-out Incorrect GP diameter Reduce GP diameter to fit into cut-out Build up of foreign matter between lenses GP base curve too flat Steepen GP base curve by 0.50D and adjust power Excessive edge lift of GP lens Reduce edge lift of GP lens Base curve of soft lens too steep Flatten base curve of soft lens by 0.3mm Diameter of soft lens too large Reduce soft lens diameter by 0.5mm GP base curve too steep Flatten GP base curve 0.50D and adjust power Water content of soft lens too low Increase water content of soft lens material Dk of GP lens too low Increase Dk of GP lens material GP base curve too flat Steepen GP base curve 0.50D and adjust power Soft lens base curve too steep Flatten soft lens base curve by 0.3mm Edge of GP lens too thick Reduce edge profile of GP lens GP diameter too large Reduce GP diameter to fit into cut-out Incompatibility with material Call Consultation for best material recommendation Care system not followed or not adequate Discuss care system with patient and change as necessary GP lens too large trapping debris in cut-out Reduce GP diameter to fit into cut-out Base curve of soft lens too flat Steepen soft lens base curve by 0.3mm Diameter of soft lens too small Increase soft lens diameter by 0.5mm Unacceptable vision on eye chart GP Lens not centered Poor visual acuity on delivery or first follow-up Soft lens not centered Corneal edema Vision decreases during the day GP lens dislodges Deposits Excessive movement Initial discomfort Too little movement Base curve of soft lens too steep Flatten soft lens base curve by 0.3mm Diameter of soft lens too large Reduce soft lens diameter by 0.5mm NOTE: The gas permeable lens should be rinsed with saline or a multi-purpose soft lens solution prior to inserting it into the soft lens. 17 www.xcelcontacts.com FLEXLENS® L ARG E DIAMETE R Custom Soft Large Diameter The Flexlens Large Diameter is ideal for protection of eyes that have undergone keratoprosthesis (K-Pro/Alphacor), conditions where conventional soft lenses are not large enough in diameter to fit properly (i.e. megalocornea, pterygia, etc.), and refractive ametropia when large diameter soft lenses are needed to provide adequate centration. Lens Design The Flexlens Large Diameter is a spherical soft lens made in a large diameter often used for therapeutic purposes. Due to the large diameter, the posterior surface of the lens is three curves unlike standard spheres which are two curves. The anterior side has a lenticular cut to reduce overall lens thickness.

The ideal lens fit should exhibit good centration with approximately 0.25 to 0.50mm of lens movement in primary position. If upon evaluation, the lens rotates more than 10 degrees and your over-refraction does not yield good visual results, consider a change in base curve and/or diameter prior to ordering a new lens that incorporates the cross cylinder as determined by your over-refraction. If lens rotates 10° or less and yields a stable overrefraction then re-order based on new lens that incorporates the cross cylinder as determined by your over-refraction. 21 www.xcelcontacts.com FLEXLEN S® TORIC Troubleshooting Patient Symptoms Objective Findings Possible Causes Plan Sphere/cylinder off axis If over-refraction yields good results, reorder new powers indicated Diameter too small Increase diameter by 0.5mm Base curve too flat Steepen base curve by 0.3mm and incorporate over refraction.

Step 2 Insert lens Once the trial lens is inserted and allowed to settle evaluate the fit for movement, and centration. The ideal lens fit should exhibit good centration with approximately 0.25 to 0.50mm of lens movement in primary position. Step 3 If the lens decenters up, down, left, or right, the base curve is most likely too flat and the next steeper base curve should be tried and evaluated. Push Up Test If the lens centers well, a simple push-up test will verify if the base curve is appropriate for the patient. To perform a push-up test, place your index finger on the patients lower lid margin and manually push the lower lens edge upward to the lower limbus. Release your finger pressure from the lower lid and evaluate the lens movement. If the decentered lens slowly drops into a center position, the lens to cornea relationship is appropriate. The base curve relationship may be too flat if the lens remains in a superior decentered position, or if the edge standoff is noted as the lens reaches the lower limbus. If this occurs, the next steeper curve/diameter should be evaluated. A steep fitting lens will exhibit resistance to the manual manipulation of the push-up test. In this situation, the next flatter base curve should be tried and evaluated. Step 4 Final Evaluation 27 Once the ideal fit is achieved perform a sphero-cylinder over refraction to determine best distance acuity. Once best distance correction is determined over-refract for best near vision preferably using hand held lenses. If the over refraction does not result in acceptable visual acuity in either distance or near consider a change in base curve and or diameter and repeat the over refraction procedure.

With a thin lens profile, this lens allows quick and easy adaptation to lens wear. Lens Design The Apex™ Keratoconus Lens is an aspheric thin lens design. This proprietary design is based upon the belief that those patients who are successful with GP lenses must be fitted with a lens that minimizes apical interaction, avoids impingement of the peripheral cornea, specifically in the flatter superior quadrant, and places the optical zone over the pupil. In order to meet this challenge, the posterior surface has a spherical optical zone radius small enough to allow tear exchange yet large enough to provide good vision without excessive flare. In addition, the posterior lens surface has enough eccentricity to adequately align with the flattening seen in the peripheral keratoconic cornea.

This design has a number of inherent “fitting forgiveness factors” to aid lens performance. OBJECTIVES: • Maintain centration of the spherical posterior optical zone over the visual axis to maximize vision and minimize flare. • Minimize interaction of the lens and the typically more elevated corneal apex. • Establish a “grip” or fulcrum points along the horizontal meridian to maintain centration of the lens. • Avoid impingement in the peripheral and mid-peripheral cornea, especially in the superior quadrant. Impingement can result in limited wear time, poor comfort, inferior lens decentration, and poor tear film replenishment during the blink that can result in epithelial breakdown. • Consider the use of a topical anesthetic for patients who are not currently wearing GP lenses. By blocking the reflex tear mechanism, and the use of wratten filter, a more accurate fluorescein pattern may be determined. Apex is indicated for the early, moderate and advanced keratoconus patient. With a thin lens profile, this lens allows quick and easy adaptation to lens wear. Step 1 Select Base Curve Step 2 Evaluate Diameter Step 3 Determine Periphery Step 4 • Insert the “mean” diagnostic lens (45.00D -4.00 9.3) on the eyes(s) regardless of keratometry. • Apply proper amount of fluorescein and observe with a cobalt light. • If a constant “black” appearance is observed over the corneal apex, steepen the base curve until a “lightening” is observed during the blink. • If the corneal apex is vaulted or a bubble is observed trapped beneath the lens, flatten the base curve. • If lens is decentered, increase lens diameter. • If proper centration is achieved and inferior edge stand off is observed, decrease lens diameter. • If poor tear exchange over the apex is observed during the blink, consider reducing the diameter. • Three edge lift values available are steep, medium, and flat. (all lenses in the diagnostic set are medium) • If insufficient edge lift is observed, consider the next flatter edge lift value. • If excessive edge lift is observed, utilize the next steeper edge lift value. • Over-refract the most appropriate diagnostic lens to determine lens power to be ordered.

Lens Design The initial premise for the Essential Solution design was to be able to deliver excellent vision not only at distance and near, but at the all important intermediate range. This is achieved by combining the aspheric back surface of the Essential multifocal with the near vision benefits of the X-Cel Solution front surface, segmented, translating design. This combination results in a high performance design with a thinner lens profile that delivers up to 3.50 diopters of add power, providing excellent near correction for even the most mature presbyopes. The design is quite thin for a ballasted lens and the decreased lens mass makes for a very comfortable fit. And importantly, the unique front surface provides distance and near optical centers that are adjacent to each other delivering “no jump” optics. Thus, the patient has no image jump when looking from distance to reading tasks.
