Study finds hyperosmolarity of the ocular surface may impact cataract surgery

Article

TearLab recently announced that preliminary results of the TearLab Cataract Study, which evaluated the relationship of a hyperosmolar tear film on keratometry readings.

San Diego, CA-TearLab recently announced that preliminary results of the TearLab Cataract Study, which evaluated the relationship of a hyperosmolar tear film on keratometry readings.

TearLab reports interim results of dry eye study

The study demonstrated that hyperosmolar patients demonstrated a wider variation in keratometry calculations between visits relative to the normal osmolar group. In the hyperosmolar group, 16 percent of hyperosmolar eyes had more than 1.00 D of change in K cylinder values between the first and second visit.

"This study demonstrates the importance of evaluating osmolarity during surgical planning in order to ensure that pre-surgical keratometry readings are not compromised by hyperosmolarity of the ocular surface,” says Doyle Stulting, MD, president of the Stulting Research Center, Woolfson Eye Institute, Atlanta.

The study will be submitted for publication to the Journal of Cataract and Refractive Surgery
