With a foundation of over 40,000 scleral profilometry examinations, Visionary Optics’ research indicates that most patients’ corneal and scleral shapes do not conform to scleral lens designs based upon peripheral curve systems; which are the majority of lens designs available to you and your patients.
Data required to fit the Latitude® lens is based upon an iContour (or sMap3D™) profilometry examination.
Latitude®’s uniquely contoured design was developed to allow for an exact fit to the ocular, corneal, and scleral surfaces (shapes).
This uniformity of Latitude® lens to ocular surface clearance is critical to ocular surface health since this revolutionary lens was created to ensure that oxygenation to the cornea and limbus is optimized.
Yes. There is no pre-determined curved system for the Latitude®. The lens is designed completely from iContour (or sMap3D™) profilometery data (over 1 million points!) This lens cannot be empirically fit.
First and foremost, we have to be provided with a good iContour (or sMap3D™) exam. Because the Latitude® design relies solely on iContour data to contour the eye, we need as much data and coverage as possible. Second, we need to ensure that the patient was not wearing a lens directly before the exam. Please ask your patients to be out of their corneal or scleral lenses at least 2-3 days minimally, optimally 1 week. If both of those occur, we have a very high rate of 1st fit success!
Technically, every patient could benefit from a Latitude® lens. It offers a completely contoured, unique fit for each patient, to improve comfort, vision and ocular health.
The Latitude® lens is a premium freeform customized lens design which may be reserved for more complicated fits involving a larger degree of irregularity, scleral toricity, asymmetric keratoconus/ectasias, pingueculas, bilateral elevations and patients who have had multiple failed fits, to name a few.
We are also seeing a link between corneal and scleral astigmatism that leads to excessive limbal clearance. These would be excellent candidates for the Latitude® lens to offer more consistent and appropriate clearance over the limbus.
Just like any other scleral lens fit! You will finalize and troubleshoot as you normally do; however, you should expect to experience minor adjustments being required, if any. Please review our Latitude® Guide or contact our Consultation Department for more information!
Some of our doctors are fitting most of their patients with Latitude® lenses. Others prefer to directly indicate to Visionary Optics’ iContour Consultants which patients they want to fit with the Latitude®. Many decide based on our consultant’s recommendations.
Visionary Optics consultants analyze each patient’s unique iContour (or sMap3D™) data set and eye shape to determine if Latitude® or Europa design is indicated. Next, our consultants communicate the design shape recommendation to the doctor and/or staff. We will only process Latitude® design after direct approval from the doctor and/or staff. If a doctor elects to use the Europa lens design, we will manufacture the Europa lens, with the understanding that the pre-designed curve system cannot fully address the asymmetry that is inherent in scleral lens fits using a Europa or any other scleral lens design available at this time.
We offer our same risk-free warranty that includes a 100% cancellation policy within 90 days. Our goal is to provide you with a successful fit every time. If this is not possible, a full refund is provided. We do limit the fit to 2 remakes (3 lenses in total). This provides more than sufficient opportunity to address adjustments that might be required or requested.
Our latest white paper, Profilometry in Practice: Enhancing Efficiency, Fit Success, and Patient Satisfaction, explores how practitioners are using profilometry— not to reinvent how they fit lenses, but to make the process more efficient, more precise, and more scalable.
