Scleral lenses are an incredibly important treatment modality for dry eye disease. They are also very effective to improve vision from irregular astigmatism after refractive surgery (SMILE/LASIK/PRK/RK) and from corneal ectasias including as keratoconus, keratoglobus, and pellucid marginal degeneration.
Data Driven Scleral Contact Lens Fitting
Scleral topography scans using Eaglet Eye Surface Profiler (ESP) and impression molds using the 3D EyePrint technology
Scleral lens fitting has reached a new level of success with recent advances in surface profiling and impression molding measurements. In the past, scleral lens fitting was performed by laborious and imprecise fitting sets. At FishmanVision, we now offer 3 different DATA driven methods for achieving a precise scleral lens fit.
- Corneal and Scleral Lens Imaging. We use the Eaglet ESP scanning device to optically profile the ocular surface. The Eaglet ESP captures over 350,000 data points across a 20 mm diameter area of the ocular surface. This data is transmitted to our scleral lens designer (at ScanFitPro) to build a scleral contact lens based on the patient’s actual surface shape of the cornea and sclera. The majority of “normal” ocular anatomy eyes are amenable to this method.
- EyeFitPro Impression Molds: We use the EyePrint mold fitting system to create a mold of the patients eye then use 3D scanning imaging to create a precise image of the eye surface. Using this data, the scleral lens can be designed with a high level of accuracy.
- EyePrintPro Impression Molds: The same impression mold process as EyeFitPro, but with an even higher level of designs for corneal and conjunctival irregularity and for utmost comfort. EyePrintPRO allows patients with ocular disease, complicated optics, and severely irregular ocular surfaces to experience the vision, comfort, and ocular health benefits of customized contact lenses. The numerous benefits of the EyePrintPRO are enabled through patented Elevation Specific Technology™ (EST)
FishmanVision uses the Eaglet Eye’s Eye Surface Profiler (ESP) to create a surface map of the eye. This data is then sent to build a “custom” contact lens.
Above is an image from the Eaglet ESP showing the full scleral topology and corneal topography.
EyePrint Impression Mold. Above is an ocular impression (i.e., a mold) of an eye that is used to design the Eyeprint scleral lens. The EyePrintPRO Designer software computes the four zone back surface of the lens. Due to the unique rotational stability of the EyePrintPRO device, this device provides a perfect delivery system for premium optics, such as Decentered Optics, Toric, Multifocal, and Optical Prism (in any direction).
