INTRODUCING 
FITCONNECT® 3.0

The only lens you'll ever need.

Take control with the only lens that lets you independently modify key parameters in each quadrant for an optimal fit.

Sagittal depth

  • Optimizes proper vaulting over the cornea for ocular health and lens comfort

Quad-Limbal zone

  • Fine-tunes clearance over the limbal area to prevent limbal compression, tissue entrapment, and suction

Mid-peripheral corneal zone

Featuring Quad-Elevation™

  • Allows independent modification of the mid-peripheral corneal zone in a quadrant-specific manner

Haptic landing zone

  • Ensures a stable fit by adjusting the lens where it lands on the sclera

The only lens featuring Quad-Elevation™

Quad-Elevation allows optometrists to independently modify each quadrant of the lens, offering precise control over the mid-peripheral zone without affecting other areas, ensuring faster, more stable, and customized fits for every patient.

Proven by research to adapt to every eye.

Explore the research behind BostonSight SCLERAL and see how our lenses deliver enhanced comfort, stability, and long-term ocular health for your patients.

Indian Journal of Ophthalmology

A statistically significant improvement was noted with BSS lenses compared to baseline. Front surface eccentricity (FSE1) lens provided the best CDVA (corrected distance visual acuity) in most of the eyes and a gain of 6 letters. SLs can be considered an effective option that corrects a significant amount of HOAs and enhances visual performances in PMD eyes without the need for an aberrometer for more custom HOA correction.

Eye & Contact Lens

Study fit 15 patients with varying FSEs (FSE0, 1 and 2).

"BostonSight SCLERAL lenses with varying eccentricities corrected a significant amount of HOAs and improved corrected distance visual acuity (CDVA) and contrast senstivity (CS) in keratoconus patients. Practitioners should be aware of this distinct feature of SLs and use it as needed to improve visual performance."

Eye & Contact Lens

Compared scleral lenses with a quadrant-specific (study lens) or a spherical (habitual lens) landing zone. SLs with spherical or quadrant-specific landing zones provide good vision and do not affect IOP (intraocular pressure) or corneal thickness.

Tear exchange is greater under spherical lenses than under quadrant-specific lenses, however, the quadrant-specific lens provides greater patient comfort. (BSS is a quadrant-specific lens)

Ophthalmic and Physiological Optics

BostonSight SCLERALs were found to be very effective in improving vision, contrast sensitivity (CS) and reducing HOAs in keratoconus. Lenses with varying fluid reservoir (FR) thickness showed equal effectiveness in visual performance and reducing HOAs. FR thickness should be considered an important factor to provide better vision and CS by minimising HOAs, as well as to maintain the normal physiology of eyes with keratoconus.

Journal of Neuro-Ophthalmology

Patient was not an ideal surgical candidate; Thus, BostonSight SCLERAL lenses in 18.5mm diameter were used. Used lens height, vault and sag as a lid crutch. Distributed the weight of increased vault over a larger diameter. In follow-up visits the patient did not experience any allergic symptoms, wore lenses 8-9 hours per day, noted significant improvement in dryness and day-to-day senstivity, noted improved overall confidence and quality of life. Patient visual acuity remained at 20/25 in both eyes.

Optometry and Vision Science

Beta-test inside BostonSight followed by KOL test; study showed average of 2 lenses per eye needed to complete fitting process, which is consistent with BSS/PowerBI internal data; visual improvement (likely FSE), a reduced need for mid-day removal.

Contact Lens & Anterior Eye

Patients with persistent corneal epithelial defects were treated with scleral lenses, including BostonSight SCLERAL. Sls provided support to ocular surface (beyond hydration, pain relief and visual acuity). Promoted healing. ODs in MD practices and research settings are more likely to see this condition.  All eyes observed complete re-epithelialization with a mean time of 11.1 ± 5.5 days.  Visual acuity improved in all but one patient.  No complications were observed during treatment. SLs provide the corneal epithelium with hydration, oxygen permeation, and protection from mechanical forces;  facilitating healing of persistent corneal epithelial defects.
