Scleral Lens Debuts

X-Cel Contacts recently announced the addition of the Atlantis Scleral lens to its toolbox of irregular cornea designs. The company says that Atlantis is a scleral lens design that performs well on any patient who has an irregular cornea, including keratoconus, pellucid marginal degeneration, corneal transplants, post-refractive surgery, and post-corneal rings as well for patients who have ocular surface disease. The Atlantis proprietary lens design was developed to provide a problem-solving solution along with a simplified fitting system with the 1-2-3 fit strategy, according to the company. X-Cel says that the unique peripheral curve calculation will allow central clearance while providing good distribution of pressure in the landing area, adequate edge lift, and overall superior comfort. The design consists of three proprietary zones that can be manipulated independently to produce one of the widest ranges of lens sagittal depths available, according to the company.

Parameters of the Atlantis scleral lens include base curves of 6.50mm to 9.00mm in a 15.0mm diameter, 7.03mm to 9.00mm in a 16mm diameter, and 7.18mm to 9.00mm in a 16.5mm diameter in powers of +20.00D to −20.00D in 0.25D steps. Atlantis lenses are manufactured in Boston XO and Boston XO2 (both Bausch + Lomb), and all are plasma treated.

The Atlantis fitting set includes a fitting guide, patient application and removal take home card, small and large DMV suction cups, lap towels, and unpreserved single-use saline packs. For additional information, contact an X-Cel consultant at (800) 241-9312 or xcelinfo@walman.com.

One-Week Lens Enters Market

Hydrogel Vision Corporation (HVC) has expanded its product line with a new lens and a new modality: Icuity H2O—one-week replacement. It’s a new option for patients who would benefit from more frequent lens replacement, but don’t want to incur the cost of a daily disposable lens, according to the company.

HYDROGEL VISION CORPORATION’S ICUITY H2O HAS A WEEKLY REPLACEMENT SCHEDULE TO IMPROVE COMFORT AND COMPLIANCE.

HVC says that Icuity H2O will allow patients to replace their lenses weekly for about the same price they’re now paying for two-week replacement and one-half the price of one-day lenses. The company also says that weekly replacement helps with compliance: two-week is harder for patients to remember, and one-month allows more time for deposits to accumulate on the lens surface. With one-week replacement the lenses are cleaner, and it’s easy to remember when to replace them—start a new week, start a new lens, according to HVC.

Icuity H2O is manufactured in hioxifilcon A material. Parameters include a Median and Steep base curve: Median +6.00D to −10.00D and Steep −0.25D to −10.00D. Free diagnostic sets of Icuity H2O are available directly through Hydrogel Vision and through any of the company’s authorized distributors. Call (877) 336-2482 or visit www.hydrogelvision.com.

New Scleral Option for Presbyopes

Advanced Vision Technologies (AVT) now offers the AVT Scleral Multifocal featuring a back-aspheric, distance-center, Tangent Carrier design. The AVT Scleral was the first design incorporating adjustable tangent carrier angles to raise or lower the landing angle of the lens, improving the alignment fitting relationship on the sclera, according to the company.

The AVT Scleral utilizes a simplified 18 Lens Fitting System featuring a series of sagittal values utilizing a combination of three central base curves, three tangent angle carriers, and three diameters. Diameters of 16.1mm, 16.6mm and 17.1mm all incorporate a large optic zone, improving limbal clearance, according to AVT. Custom diameters are available, and add powers are available from +1.00D to +3.00D.

AVT says that the new lens is a presbyopic option for all types of patients with normal to highly irregular corneas. Call (888) 393-5374 or visit www.avtlens.com.
