TearLab Osmolarity System was highlighted on PCON SuperSite Feb. 28, 2011 at the winter meeting of ESCRS in Istanbul where she presented results on a study she conducted using TearLab  quoting Dr Beatrice Cochener (pictured here),  ”Consequently, we were able to define the population who needs preoperative treatment and more intense and prolonged postoperative treatment. We were also able to test the changes after the use of lubricants and to compare the efficacy of different agents. This device could greatly improve our standards of care.”

ISTANBUL, Turkey — Minimizing postoperative dry eye is a major goal of refractive surgeons, with careful preoperative evaluation of the ocular surface playing a crucial role in preventing the condition, a physician said here.

Dry eye is the most common complication of laser refractive surgery, Béatrice Cochener, MD, said, in a keynote lecture at thewinter meeting of the European Society of Cataract and Refractive Surgeons. After LASIK, 50% of patients develop common dry eye symptoms, and 10% evolve to more severe disturbances, such as fluctuation of vision, glare and severe discomfort, she said.

The TearLab Osmolarity Test system (TearLab Corporation) is a device that measures tear osmolarity and provides reliable data for preoperative ocular surface assessment.

“By using this new platform, we found that 44% of the patients have asymptomatic dryness before surgery, with no correlation between objective tests and subjective scores,” Dr. Cochener said. “Consequently, we were able to define the population who needs preoperative treatment and more intense and prolonged postoperative treatment. We were also able to test the changes after the use of lubricants and to compare the efficacy of different agents. This device could greatly improve our standards of care.”
