What is a scleral lens?
A scleral lens is an oversized “contact” lens that rests on the sclera (the white of the eye) and vaults (does not touch) the cornea. Scleral lenses are designed to treat a variety of eye conditions that impact the function of the cornea and provide relief from ocular surface disease.
Who are the best candidates for BostonSight SCLERAL?
BostonSight SCLERAL is an FDA-cleared lens design for the treatment of irregular corneas and ocular surface disease including dry eye. With BostonSight SCLERAL you will find a great resource for all your irregular cornea cases (not just the most challenging ones), and for your dry eye/OSD population.
How is the BostonSight SCLERAL lens different from PROSE?
BostonSight PROSE is a comprehensive medical treatment model to restore visual function to patients with complex corneal disease. BostonSight SCLERAL is our data-driven product delivering doctors and patients unparalleled scleral lens design.
Is any special equipment, certification or software required to fit BostonSight SCLERAL?
Our fitting system offers superior value. There is no extensive training or special equipment required to fit BostonSight SCLERAL lenses. Our offering includes FitConnect, our web-based design and ordering platform, and our value-added Beyond the Fit™ Program.
For empirical free-form fitting using Smart360™ technology, a practice must have a Pentacam CSP or an Eaglet ESP.
What additional fees should I expect when fitting BostonSight SCLERAL?
Pricing varies based on market. In the U.S. and Canda, with our value-added, all-inclusive pricing, there are no extra fees throughout the fitting process. Customizations are included with unlimited, no-charge modifications within 120 days. No extra charge for change in diameter (within respective FitKit® options), change in base curve, change in material, toric periphery, front surface astigmatism, or channels.
SmartSight HOA® and Tangible Hydra-PEG coating both incur a one-time fee per lens. (SmartSight HOA may not be available in all markets)
What diameter lenses does BostonSight SCLERAL offer?
BostonSight SCLERAL offers two convenient triple-play FitKit™ options: 16, 16.5, & 17mm and 18, 18.5, & 19mm. Each diagnostic set includes 3 diameters in ONE kit making it even easier to find the perfect fit. Our FitKit™ offers an efficient fitting process with right and left eye anatomical designs. The same diameter range plus 17.5mm is available via our free-form empirical design feature: Smart360™.
Which diameter FitKit® should I get for my practice?
Dr. Carrasquillo, our VP of Clinical and Professional Affairs and one of the chief architects of BostonSight SCLERAL, would say that our 18.0mm and 18.5 mm designs address most OSD needs beautifully, and for really ectatic grafts or cones, the 19.0mm design is the winner. If you see a lot of ectatic cones and grafts (>75D) working with the 18-19mm FitKit is advisable. For smaller HVIDs, smaller apertures, more regular corneas, and patients with tighter lids and difficulty with application and removal, working with the 16-17mm FitKit is advisable.
What are the powers of the FitKit trial lenses?
All trial lenses in the BostonSight SCLERAL FitKits have +0.25 power with a base curve of 8.00. These parameters can be modified within FitConnect when designing your patient’s lens.
How should BostonSight SCLERAL FitKit® diagnostic lenses be cleaned and cared for?
Please refer to our Disinfection Protocol for multi-patient trial lenses, based on ISO 19979:2018; Ophthalmic Optics-Contact Lenses-Hygienic Management of Multi-Patient Use Trial Contact Lenses.
What is SmartSight® technology?
All BostonSight SCLERAL lenses are designed with SmartSight front surface eccentricity (FSE) values. SmartSight provides superior quantitative and qualitative vision and is available in three options. FSE1 is the standard value. In general, when dealing with an irregular cornea, if the FSE1 value is not providing the best visual outcome, we recommend starting off with the FSE2 before trying FSE0. And when dealing with a regular cornea, i.e. DES, we recommend starting with the FSE0 before trying FSE2.
For correction of more challenging aberrations, we suggest SmartSight HOA technology for custom HOA correction. (SmartSight HOA may not be available in all markets)
With SmartSight®, how do you choose whether to use the FSE0 or FSE2 lens first?
Dr. Karen Carrasquillo, our VP of Clinical and Professional Affairs and one of the chief architects of BostonSight SCLERAL, would say there’s no rule of thumb of when to use FSE2 vs FSE0, but in general, when dealing with an irregular cornea, if the FSE1 value is not providing best visual outcome, we recommend to starting with the FSE2 before trying FSE0. And when dealing with a regular cornea, i.e. DES, we recommend starting with the FSE0 before trying FSE2.
What is SmartSight HOA® and how much does it cost?
SmartSight HOA works by scanning the patient’s eye while wearing their final BostonSight SCLERAL fit lens. Your aberrometer determines residual HOAs, and the wavefront data is then exported to BostonSight’s FitConnect® lens design software. Once the order is finalized in FitConnect, the data is automatically transferred to our lathe for manufacturing. All orders incorporating HOA design will incur a one-time additional fee per lens. For additional pricing information, please reach out to your Account Manager.
Please note that a free 30-minute certification training is required to get started with SmartSight HOA. (SmartSight HOA may not be available in all markets)
What materials are available for BostonSight SCLERAL?
Our preferred material is the Optimum line by Contamac, Optimum-Extra, Optimum-Extreme, and Optimum Infinite. Other material options are Boston® EQII, Boston® XO2. Tangible Hydra-PEG is available. We also offer clear and ice blue tints. Ice blue is available only in Boston XO2.
What is your warranty policy?
BostonSight SCLERAL offers an unlimited exchange period, at no additional cost, for 120 days. Lenses can be returned for credit (with the exception of non-refundable shipping charges, Hydra-PEG coating, and SmartSight HOA) within 120 days of the date of the invoice.
The original invoice clearly marked “patient cancellation” must be included in the package with the applicable lenses and returned to BostonSight Specialty Lenses, ATTN: Lab Director, 464 Hillside Avenue, Suite 205, Needham, MA 02494.
All lens order cancellations and credits are processed through our Billing Department. For questions or to check the status of a credit, please contact 888-SCLERAL, option 4, or billing-inquiries@bostonsight.org.
Do you offer patient discounts?
We offer FitAssist Vouchers to our customers. For every 12 patients fit with BostonSight SCLERAL, your practice receives a voucher for a free fitting for one patient in need, for one or both eyes. Patients must attest to financial need and vouchers expire 24 months from issue date. Additional details can be found here.
Are BostonSight SCLERAL lenses shipped wet or dry?
BostonSight’s manufacturing lab ships lenses wet to keep them conditioned for optimal wear. Each lens will be supplied in a non-sterile plastic lens storage case filled with Boston SIMPLUS® Multi-Action Solution. Boston SIMPLUS Multi-Action Solution is a cleaning, disinfecting, and conditioning product that has an added protein remover. The solution needs to be replaced with fresh, sterile, and unexpired solution within 30 days from the manufacture date indicated on the lens label. Please refer to the Package Insert for additional instructions on lens care and handling.
Note: TRIAL SETS will continue to be shipped dry.
Does BostonSight SCLERAL offer a multifocal option?
Multifocal optics are in our innovation pipeline. This is planned for 2024.
Does BostonSight SCLERAL offer a free form design option?
Yes, BostonSight SCLERAL offers Smart360® free-form lens design. OCULUS Pentacam CSP and Eaglet ESP users are able to create a free-form lens, based strictly on the patient’s ocular surface shape. With Smart360, you can design a lens from 16mm to 19mm. For focal elevations like pinguecula or other scleral abnormalities, you can request a SmartChannel to vault over these areas by specifying the width of the channel and depth. Once you receive the first free-from lens, you can also tweak, as needed, within the FitConnect® platform.
Does BostonSight SCLERAL have a feature to vault anatomical obstacles?
You can add SmartChannel® technology to your lens design in FitConnect®. SmartChannels vault anatomical obstacles and can be used to promote fluid-ventilation and reduce suction. A maximum of 4 SmartChannels can be added to a lens.
Do your lenses have an expiration date per say? How long are they usually good for?
There is no set timeframe. Well cared for lenses that remain comfortable with good visual acuity upon regular visits may last multiple years. The most important thing is that regular, annual fit assessments (at the practitioner’s discretion) are made to determine if any of the changes to the fit need to occur.
What is the difference between BostonSight SCLERAL lenses with one and two black dots?
Our lens design, based on scleral anatomy, offers right and left anatomical design with unique scleral shape profiles. One dot identifies the RIGHT lens and two dots identify the LEFT lens. For more information, please refer to our FitGuide®.
Is there a color or tinting option for BostonSight SCLERAL?
Yes. BostonSight SCLERAL now has Boston XO2 material available in ice blue. The composition of the material is the same as the regular XO2 material, including UV protection. The ice blue option may be helpful for patients who have difficulty seeing the clear lenses.
Can you sleep with BostonSight SCLERAL lenses in?
Daily wear contact lenses are not indicated for overnight wear, and patients should be instructed not to wear contact lenses while sleeping. Please refer to the full BostonSight SCLERAL Package Insert for more information.
