Custom Contact Lenses

What can be customized

• Base curve and diameter, for corneas that are steeper, flatter, larger or smaller than stock lenses assume
• Power in any amount, including very high nearsightedness and farsightedness beyond stock ranges
• Astigmatism in any cylinder and axis, with stabilization designed for your lids
• Multifocal optics tuned to your reading needs and pupil size
• Thickness profiles, for instance thicker centers that mask mild corneal irregularity
• Materials, including high oxygen silicone hydrogels and low-dehydration materials for dry eyes
• Tints and hand-painted designs for prosthetic and cosmetic needs

Custom soft lenses

Lathe-cut soft lenses are made one at a time to any specification. They suit patients with high astigmatism or prescription, unusual corneal size, mild keratoconus, and presbyopia with astigmatism, and patients who simply could never get a stock lens to sit comfortably. They are replaced quarterly or yearly rather than daily.

Custom rigid, hybrid and scleral lenses

Every rigid gas permeable, hybrid and scleral lens is made to order, and the range of customization is wider still, and can include back surfaces that match an irregular cornea point by point, scleral designs shaped to an asymmetric sclera from scleral imaging, and front surfaces that correct higher order aberrations. These are the lenses for keratoconus, post-surgical corneas and transplants.

The fitting

Corneal topography and, where relevant, scleral imaging provide the measurements. A diagnostic lens establishes the fit and vision, the custom lens is ordered, and it is checked on the eye after arrival and refined if needed. Most custom fittings are complete in two to four visits.
