Artemis 3 - High-Resolution Ultrasound Eye Scanner for Ophthalmology

Not for Sale Pending 510(k) Clearance

Artemis 3
The Artemis is a very high frequency (VHF) ultrasound eye scanner.  The technology was originally developed by leading ophthalmologists and researchers at Cornell University.  It was subsequently commercialized by Ultralink who placed a limited number of Artemis (Artemis 1 and 2) systems that were used primarily for research. In September 2007, ArcScan acquired Ultralink and has now developed the next generation Artemis 3.

Technology

The magic behind Artemis 3’s scanning technology comes from the linear and curved arc tracks that support its VHF ultrasound transducer on micron-smooth fluidic bearings.  Acting together, these tracks allow the scan pivot point to be placed at the center of curvature of a cornea or lens surface, which keeps the beam perpendicular to that surface throughout the scan.  The Artemis 3 will be able to produce full maps of the cornea and lens capsule using this method.  The Artemis 3 headrest and fixation target ensure precision by keeping the eye in fixed and stable alignment with the scanner.

ArcScan’s ultrasonic technology has the ability to precisely measure epithelial and stromal layers within a patient’s cornea, which is expected to improve LASIK outcomes for some patients.

Unlike optical technologies, the Artemis 3’s ultrasonic technology is able to visualize structures behind the iris. Its arc scanner is designed to enable very precise measurements of structures such as the lens capsule. It is expected that the Artemis 3’s arc scanning design and ultrasonic technology will set a new standard in anterior segment measurements that will provide important information to surgeons planning implantation of the new phakic and accommodating lenses. 

Digital signal processing and feature-rich software will enable clinicians to easily and reliably map three dimensional structures of patients’ eyes.

Product Goals

To provide the refractive research and surgical communities with a superior diagnostic instrument to enable them to better design phakic and accommodative lenses as well as to reduce the risk of bad outcomes in corneal surgeries and lens implants. ArcScan has accomplished this goal with the Artemis 3 in the following ways:

  • Images generated in a few seconds at frequencies up to 50 MHz so that high resolution corneal scans can be made showing epithelial layers, Bowman's membrane and, if present, LASIK scars older than 10 years.
  • Images generated in a few seconds at frequencies up to 40 MHz that show sulcus to sulcus, 95% of the lens capsule and zonules.
  • Precision imaging of a lens accommodating.
  • Detailed imaging of trabecular meshwork and supra-choroidal space for operative planning and post operative assessments for treatment of aqueous outflow systems.
  • Advanced automated post-processing available while the procedure is being completed.
  • The Artemis 3 is designed to be user friendly. An entire arc scan procedure can be accomplished in about 2 minutes per eye with auto-centering.
  • Advanced eyepiece and headrest design for patient comfort and ease of operator use
  • Updating an advanced user interface so the scanner will store, transmit, and receive images in DICOM format so the user to exchange images with other DICOM-compatible devices.
  • Remote diagnostics and overnight part replacement.

Primary Applications

Artemis 3 will enable ophthalmologists to see the eye’s structures in minute detail as an aid to diagnosis and surgical planning.  Ophthalmologists may use Artemis 3 as part of their patient work up for laser refractive surgery, for new emerging refractive surgery procedures including corneal, phakic and accommodating lens implants, and for preoperative planning and assessments of new surgical procedures (stents, canaloplasty, others) for treatment of aqueous outflow systems in glaucoma.  

Artemis Key Features & Benefits

Previous Artemis systems have the reputation for being very technically advanced research diagnostic devices.  In developing Artemis 3, ArcScan has taken the technology to the next level and made it simple enough for everyday use in any refractive surgical practice.
Artemis 3 is:

Patient Friendly

  • Entire scanning process from patient set up to report generation takes about 2-3 minutes
  • Multiple meridian (4-12)  scans only take seconds improving patient comfort
  • Comfortable disposable eyeseal keeps the patient dry
  • Self-adjusting headrest improves patient stability and comfort during scanning

User Friendly

  • Auto alignment for quicker set-up and accurate image registration
  • Immediate single-click report generation for faster patient throughput
  • Standardized DICOM images for data exchange with other devices

Reliable & Easy to Service

  • Only two moving parts in the scanner insures reliable everyday performance and minimal maintenance
  • Light-weight modular design for easy installation and trouble shooting
  • Remote service diagnostics for quick service turn around
  • Depot repair and exchange program for 24 -48 hour service turn around.

Versatile and Repeatable

  • Only known anterior segment scanning device that measures corneal layers, angle, and lens capsule dimensions with one product
  • High quality images with 12-bit digital image processing
  • Repeatable image registration with auto alignment
