VIP-200 Pupillometer Is a New Portable Device to Measure Pupils for Refractive Surgery

Neuroptics Inc. from Irvine, California released the VIP-200 Pupillometer, a hand-held device to screen patients for refractive surgery. The device helps eye surgeons to optimize patients for a laser-assisted in situ keratomileusis (LASIK) procedures and fitting of multifocal intraocular lenses (IOLs).   The Pupillometer can simulate scotopic, low mesopic and high mesopic light conditions and measure them in one run of 10 seconds. This makes it possible to customize pupil dependent IOLs better to patient preferences. A golf pro who needs to see best during day light or a radiologist who is reporting from a dimly lit room can be tested for their personal needs.

The Pupillometer measures pupil sizes in a range from 1mm to 9mm with an accuracy of 0.1mm. The average pupil aperture and standard deviation can be calculated. Random uncontrolled fluctuations and the vertex distance, which can vary up to 12mm in the normal population, will be compensated.  Because it may be hard for a clinician’s eye to estimate pupil size by a single picture, the Pupillometer records 3 seconds to overcome small continuous oscillations and presents an average size. Data is stored on the device, while results and a video of the measurement can be displayed on the screen or printed.

iExaminer for iPhone 4 Liberates Fundus Exams

Ophthalmoscopes are widely used to help diagnose a variety of conditions, but much like traditional microscopes they can only be used by one person at a time and sharing what one sees requires, as the old saying goes, a thousand words.

The iExaminer from Intuitive Medical Technologies in Shreveport, Louisiana is a simple iPhone 4 attachment for the popular Welch Allyn PanOptic ophthalmoscope that lets you do fundus exams and share videos and images right from the iPhone.

OptiMedica’s Catalys Precision Laser System for Cataracts Gets CE Mark of Approval

Cataract surgery is a common procedure these days, yet current methods still require the surgeon to exercise manual precision. Santa Clara, CA-based OptiMedica Corp. claims that its newly CE marked Catalys Precision Laser System will help increase the precision of cataract procedures with its combination of a femtosecond laser and integrated optical coherence tomography (OCT).

The Catalys’ OCT system automatically detects the surfaces of the patient’s lens and cornea to ensure safe and accurate delivery of laser pulses, and the company’s proprietary Liquid Optics Interface maintains a large clear optical path for the OCT imaging, laser pulse delivery, and real-time video.

Space Missions May Damage Eyes

Astronauts experience bone and muscle loss in the weightlessness of space, and now the first study of returning space travelers’ eyes suggests that prolonged amounts of time in orbit can take a significant toll on vision, although the long-term effects…
