Large Diameter Sclerals
• Standard fitting set comprising of thirteen 23mm scleral lenses
• Apical profiles range flat normal to advanced distended corneas
• Special globic or cornea plana fitting designs on request
• Material maximising oxygen permeability and surface quality

• Special globic or cornea plana fitting designs on request
• Material maximising oxygen permeability and surface quality
BOZR, BVP and optic zone projection (OZP) specified for each lens. Arithmetic OZP increments across whole range. 1.0 – 1.5mm optic decentration reducing nasal scleral bearing surface width.
BOZR range condensed to allow:
• Optimised junction between optic and scleral zones
• Reduced limbal compression
We predominantly work with Contamac materials ensuring high quality standards but are open to using others if desired.

Optosoft Ltd acquires Innovative Sclerals
In October 2023 Optosoft Ltd made the acquisition of Innovative Sclerals from Bausch + Lomb and are now the exclusive supplier of the full range of Innovative Sclerals lenses including the original full range of 23 mm and the original full range of 18 mm scleral lenses.
23mm Innovative Scleral ranges (20mm – 23mm) available; N, ON, CN, F, OF, CF
18mm Innovative Scleral ranges available; L, OL, CL, H, OH
Innovative Sclerals lenses will be manufactured from Boston XO2 material or different material on request

Quality & Support
• Scleral lens supplier to Moorfields Eye Hospital, London
• Long term support for any lens and the patient’s development using the lens
• Long term support for any lens and the patient’s development using the lens
Scleral lenses are now made using state of the art Optoform lathes giving superior optical performance and repeatability down to microns.
Specification
Range from 20 to 24mm on request.
Note that a reduction in diameter may cause reduction in apical clearance.
Increased diameter may impinge more on peripheral scleral irregularities.

Topography not a reliable indicator for initial lens.
Approximate guide for regular corneas
• OSB 150 or OSB 180 for normal flat cornea.
• OSB 210 or OSB 240 for mid range normal topography.
• OSB 270 for normal steep.
For distended topography
• Select from observation of corneal profile and use OSB 330 to
OSB 510.
• Power determined by over-refraction of lens in situ.
• Reduced diameter to 20mm or extended to 24mm available,
unlikely to have a significant impact on fitting appearance.
• Other parameter variants subject to technical and clinical
advice

Fitting set lenses fully specified i.e. diameter, optic zone sagitta,
decentration, BOZR and BVP.
If no departure from fitting set specification recording spherical over-refraction only required. Optosoft calculate final BVP including appropriate predicted allowances.
Variants from fitting set specifications are not always predictable and should be discussed case by case with Optosoft.
