For patients with irregular corneas, scleral lenses offer a versatile and effective alternative to traditional contact lenses, providing improved vision, comfort and on-eye stability. While scleral lenses are highly customizable, patients with advanced corneal conditions may require more intricate specifications than most of these lenses allow. For cases like these, Bausch + Lomb recently introduced a non-prosthetic custom scleral lens, called the Zenlens Echo, that offers additional parameter customization compared with the company’s existing Zenlens.

Along with the lens fitting set, Zenlens Echo lenses require OCT scanning, a slit lamp and profilometery, B+L points out in its press release. For each lens, clinicians can specify the base curve, sagittal height, limbal clearances and landing zone, as well as spherical and front toric optics and mid-peripheral and limbal clearance zones. No additional training or certification is required to fit these lenses, according to the company.

In the press release from B+L, the company wrote that the Zenlens is designed to fit patients with the following advanced conditions: corneal degeneration, including Terrien’s marginal degeneration, advanced pellucid marginal degeneration, Salzmann’s nodules and keratoconus; postoperative conditions, such as tilted graft (penetrating keratoplasty), post-refractive ectasia and radial keratotomy; and trauma, including chemical burns or conjunctival abnormalities.
