Clinical Performance and Surgeon Acceptability of a New Dual Mode Phacoemulsification System.

Purpose: The purpose of this first in-human study was to evaluate the overall clinical performance of the VERITAS™ Vision System in patients scheduled to undergo cataract extraction and to confirm overall surgeon acceptability.

Patients And Methods: This prospective, open-label multinational study included adults with cataracts scheduled for planned cataract extraction and posterior chamber IOL implantation. Standard small-incision phacoemulsification cataract surgery with the VERITAS Vision System was conducted.

Serial measurements increase the accuracy of laser Doppler assessment of burn wounds.

Traditional methods of judging burn depth by clinical evaluation of the wound based on appearance and sensation remain in wide use but are subject to individual variation by examiner. In addition to the clinical difficulties with burn wound management, observer dependency of wound assessment complicates clinical trials of burn wound therapy. A laser Doppler flowmeter with a multichannel probe was used to measure burn wound perfusion as a tool to predict wound outcome.

The 1996 Clinical Research award. Use of a pneumatonometer in burn scar assessment.

The evaluation of wound outcome after burn injury is a challenging problem in the performance of clinical trials evaluating potential impact on wound healing and scar formation. The purpose of this study was to determine whether an ocular tonometer could be adapted to provide an objective measurement of scar compliance. A pneumatonometer was used to perform measurements of cutaneous compliance at 8 anatomic areas (14 separate sites) on each of 17 normal volunteers and on 59 burn scars.

Early assessment of pediatric burn wounds by laser Doppler flowmetry.

Evaluation of burn wound depth in pediatric patients is often difficult. A Laser Doppler Flowmeter with a temperature-controlled multichannel probe was used to measure burn wound perfusion as a tool to predict wound outcome. The average perfusion levels for wounds that healed spontaneously in fewer than 21 days was significantly higher than the average perfusion levels for wounds that required excision and grafting or were not healed by day 21 after burn injury.

Laser Doppler flowmetry in burn wounds.

Traditional methods for judgment of burn depth by clinical evaluation of the wound based on appearance and sensation remain in wide use but are subject to individual variation by examiner. In addition to the clinical difficulties with burn wound management, observer dependency of wound assessment complicates clinical trials of burn wound therapy. A laser Doppler flowmeter with a newly designed multichannel probe was used to measure burn wound perfusion as a tool to predict wound outcome.
