Correlation of Corneal and Scleral Topography
Objectives: To determine the relationships between corneal and scleral elevation topography in subjects with corneal ectasias and normal corneas.
Repeatability in Scleral Lens Patients – sMap3D™ Corneo-Scleral Topographer
Objective: To determine repeatability of measurements using the sMap3D™ Corneo-Scleral Topographer in patients presenting for scleral lens fitting.
Extreme Reverse Geometry Fits in Post PKP Cases
Because of the extreme central flattening that can occur post-penetrating keratoplasty (PKP), these cases represent a unique scleral lens fitting challenge to optimize central and optical zone clearances.
Precision Lift for Elevated Pinguecula
This case report illustrates the use of the sMap3D™ virtual precision fit software to design a lens to vault over a localized conjunctival/scleral obstacle.
Reverse Geometry Lens Fit Extremely Oblate Cornea
Virtual fitting designed a 5.5D reverse geometry lens with high accuracy in predicted central clearance and peripheral fit, avoiding multiple stepwise changes and remakes, simplifying lens fitting and reducing patient chair time.
Scleral Lens Decentration Due to Inferior Depression
This case illustrates that scleral shape rather than size and weight of the lens can sometimes be the major contributing factor to scleral lens decentration.
Matching Scleral Design with Ocular Shape
Matching Scleral Design with Ocular Shape – Advancements in measurements and manufacturing can improve fitting efficiency and success.
The majority of practitioners fitting scleral contact lenses rely on diagnostic lenses for fitting. Diagnostic lenses primarily allow practitioners to estimate the amount of sagittal depth needed to properly vault the chord diameter of the ocular surface that is being fit.
Latitude Scleral Lens: Product Focus with Contact Lens Spectrum
Visionary Optics recently introduced the Latitude scleral lens. According to the company’s research, most patients’ corneal and scleral shapes do not conform to scleral lens designs based upon peripheral curve systems. Its answer to this dilemma was to create the Latitude lens, which has no peripheral curve system; rather, it is a freeform lens designed to contour uniformly to each eye.
Surface Coverage with Single vs. Multiple Gaze Topography – 2017 GSLS
Objectives: To determine surface coverage of measurements using the sMap3D™ corneo-scleral topographer in patients presenting for scleral lens fitting.
