New Surgical Laser More Effective. Less Expensive

February 15, 2008 - Zecotek Photonics Inc. announced the introduction of its SL 1.4 Fiber Coupled Laser, designed specifically for surgical applications in the ophthalmic market for a variety of coagulatory procedures.

Zecotek's SL 1.4 Laser reportedly offers a more effective and less expensive solution than presently used holmium lasers. The 1.4 micron wavelength can be used for a variety of coagulatory surgical procedures including Laser Thermal Keratoplasty (LTK), a refractive surgical procedure which uses an infrared laser to reshape the cornea for correction of low ranges of hyperopia (farsightedness), presbyopia (age-related loss of focus) and over-corrections from radial keratotomy and LASIK procedures. The company is currently preparing for filing for patent protection in a number of jurisdictions.

LTK treatment is differentiated from LASIK and similar procedures in that it reshapes the cornea but does not cause permanent tissue loss. The Excimer laser used in LASIK treatments emits in the deep Ultra-violet wavelengths and uses a cool beam to vaporize corneal tissue. The 1.4 micron laser line matches the absorption spectrum of water in the cornea and is considered a safer and more compatible wavelength. The treatment has the advantage of not being fully permanent, but can be sustained with periodic treatment. Other reported benefits include no scarring in the central cornea, a low risk of dry eyes and immediate vision improvement

Zecotek’s SL 1.4 Fiber Coupled Laser is undergoing initial trials in Russia, where LTK is a recognized treatment. The LTK procedure is currently under investigation by the FDA for approval in the US. The SL 1.4 laser was developed by Zecotek Laser Systems Pte Ltd. and will be supplied to bio-medical OEMs and institutions for testing and design-in purposes.
