Focus on Pupillometers
BD Ophthalmic Systems
The handheld NeurOptics pupillometer is a self-contained digital camera and microprocessor that objectively measures the diameter of the eye. With the push of a button, it captures and analyzes more than 40 images in approximately 3 seconds while a video tracking system accommodates for eye drift. The resulting measurement is accurate to within 0.1 mm.
NeurOptics' proprietary targeting system locates and locks onto the pupil position, then measures and audibly confirms a successful measurement. Active guidance markers provide visual feedback to the operator to ensure proper alignment during testing. Measurements can be reviewed by recalling stored digital images from the unit's internal memory. About 100 images can be stored.
The instrument includes an adjustable, internally illuminated LCD, with a menu-driven graphic user interface that lets you input specific information about the patient and then displays the patient's information and measurements on the LCD screen. The data can be transferred wirelessly to a printer, a multiparameter monitor or computer.
BD Ophthalmics says testing has shown that the NeurOptics is consistent from unit to unit, and from operator to operator.

PUPILSCAN II MODEL 12A
Lombart Instrument says its Pupilscan II Model 12A is as easy to use as point-and-click. The automated, microprocessor-based pupillometer uses an infrared imaging technology to digitize the pupil image, and contains sophisticated software to extract the diameter of the pupil from the captured image.
Pupil measurement is automated, so no subjective estimates are required. Lombart says automated measurement increases accuracy, reduces the possibility of error, and speeds the measurement process.
With its unique eyecup design, Pupilscan II doesn't require a dark environment to obtain optimum results. With its backlit display, it can be used successfully in nearly any ambient light environment -- from room light to total darkness.

Oasis Medical offers the Colvard
pupillometer, which the company says is ideal for accurately measuring both scotopic pupil size and corneal diameter of cataract and refractive patients prior to surgery.
Using light amplification technology, the Colvard pupillometer allows visualization of the patient's pupils in a darkened exam room. The Colvard features a reticle that provides measurement of the corneal diameter along both the vertical and horizontal axes.
The Colvard is handheld, lightweight and battery-operated, and comes with a storage case, lithium battery and instruction manual.

Introduced in 2001, the original Procyon P2000SA pupillometer from the United Kingdom quickly won acceptance among ophthalmologists for producing accurate measurements. Procyon now introduces its next-generation P3000
pupillometer, which the company says offers even better repeatability, precision and reliability of data. This new unit also features enhancements in patient comfort and improved optical target.
Procyon says the accurate, objective measurements obtained with the P3000 make it ideal for wavefront systems. This is especially true when refractive surgery patients have large pupils and precise pupil data is crucial to the outcome.

Rhein Medical's new capsulorrhexis forceps offers a unique curved shaft.
Rhein Medical introduces its latest microsurgery capsulorrhexis forceps. The Rhein Tubular Capsulorrhexis Forceps has a unique curved shaft for a more comfortable approach to the incision. The special jaws have cystotome tips for pinching and completing the circular tear, and are shorter so as not to interfere with a
sub-incisional flap. The tube is 23-gauge, allowing it to pass through a 1-mm incision. The handle is made of ultra-lightweight titanium. The instrument is also
autoclaveable, guaranteed for life, and available for a 30-day surgical evaluation without obligation.

LASIK INSTRUMENT PACK
Moria has launched its new Disposable LASIK Instrument Pack, with each pack containing a disposable, adjustable speculum specifically designed for
LASIK, a disposable scraper/hinge protector, and a disposable marker.
The company says use of the new pack eliminates instrument cleaning and damage, as well as potential complications from improperly cleaned or sterilized instruments. The reduced maintenance requirements facilitate faster patient flow and lower overall operating costs.
Used with either the Moria One Use or the new automated One Use-Plus
microkeratomes, the disposable instrument pack allows a totally autoclave-free procedure.

The new Kim Dual Horizontal/Quick Horizontal Chopper was developed by Terry Kim, M.D., of Duke
Pelion Surgical of Aiken, S.C., offers the new Kim Dual Horizontal/Quick Horizontal Chopper, an instrument that offers the convenience of two choppers on a single handle.
A traditional-style horizontal chopper is opposite a unique, triangular tip for performing a modified horizontal quick chop. The quick chop tip allows chopping of the nucleus in the horizontal plane from a central location, with traversing peripherally under the anterior capsule. This versatile chopper provides for multiple approaches for nucleus separation.
Tips on both ends have rounded edges to prevent posterior capsule damage. The instrument is made of lightweight titanium and is guaranteed for life against defects in material or workmanship.

The Evolution features a remote control.
Marco has added the wireless Evolution electronic refractor with infrared remote control to its Vision Diagnostic Systems line.
The company says this cost-effective unit gives the practitioner complete control of the refraction process through the convenient remote control.
The practitioner can pre-program the entire refraction process, increasing exam efficiency. All charts with masks, fogging and other functions can be programmed according to operator preference.
The Evolution offers a 45-degree visual field and high-contrast LCD display. It can also be integrated with chart projectors, autorefractors and lensmeters made by virtually every other manufacturer, eliminating the need for an interface box.
