Laser Vision Correction Business

Our laser vision correction products include the following:

·                  VISX STAR Excimer Laser System — The VISX STAR System is a fully integrated ophthalmic medical device incorporating an excimer laser and a computer-driven workstation.

·                  VISX WaveScan System — The WaveScan System is a diagnostic device that uses laser beam technology to measure comprehensive refractive errors of the eye and complex mathematical algorithms to derive comprehensive refractive information about the patient’s individual optical system.

·                  VISX Treatment Cards — Our proprietary treatment cards control the use of the VISX STAR System.

·                  Microkeratomes — Surgeons use microkeratomes in LASIK procedures to cut a flap of corneal tissue before treatment with an excimer laser.

VISX STAR Excimer Laser System. The laser ablations produced by the VISX STAR System are the product of a variable diameter excimer laser beam scanning system.  Seven beams that range in size from 0.65 to 6.5 millimeters are homogenized as they converge, scan, and rotate to produce a smooth ablation area on the eye.  The VISX STAR System centers on the eye and tracks eye movements in three dimensions during the procedure. Our Iris Registration technology is the first fully automated method of aligning and registering wavefront corrections for CustomVue treatment.  Iris Registration is designed to replace the current means of registration, which involves manual marking of the eye to assess rotational movement.

The VISX STAR System performs Standard LASIK, CustomVue laser vision correction, and PRK.  It also performs specialized procedures known as Custom-CAP, which treats patients who previously had LVC surgery resulting in symptomatic decentered ablations (a condition that affects fewer than 4,000 patients per year) and PhotoTherapeutic Keratectomy, or PTK, which treats corneas that are scarred or have irregularities from prior infection, trauma or underlying corneal disease.

VISX WaveScan System.  The WaveScan system displays refractive information about the patient’s individual optical system in the form of an aberration map.  This unique map, similar to a fingerprint for each patient’s eye, offers objective information about refractive errors associated with nearsightedness, farsightedness and astigmatism, as well as information about higher order aberrations that were previously unmeasurable by any other instrument.

VISX Treatment Cards. Each treatment card provides the user with specific access to proprietary software and is required to operate the VISX STAR System. Because treatment cards are required to perform procedures, there is a strong correlation between treatment card sales and the number of procedures performed on VISX STAR Systems.  Types of VISX treatment cards include: VisionKey Cards for performing standard LASIK procedures, which in the United States carries a license fee for each procedure that is purchased; CustomVue Cards for performing Custom LASIK, which carry a worldwide license fee for each procedure that is purchased; Custom-CAP Cards for performing laser vision correction with a previously decentered ablation, which carry a worldwide license fee for each procedure that is purchased; and the PTK Card, which is offered to physicians at a nominal charge to treat certain types of corneal pathologies.  Sales of our treatment cards and associated procedure fees represented approximately 15%, 8% and 0% of our net sales in 2006, 2005 and 2004, respectively.

Microkeratomes.  In the refractive surgery market, we are a worldwide distributor of the Amadeus II microkeratome system and SurePass microkeratome blades.
