Low IOP is measured with great accuracy using non-contact applanation tonometer

A non-contact applanation tonometer (Ocular Response Analyzer, Reichert) appears to be more effective than the Goldmann applanation tonometer (GAT) in assessing very low and negative IOP values using the non-contact applanation tonometer's corneal-compensated IOP (IOPcc) parameter. The GAT may be the long-accepted gold standard, but the more accurate assessment of IOP using the non-contact applanation tonometer challenges this gold standard and raises questions as to which of the two techniques is optimal in measuring IOP.

Study: Sodium hyaluronate solution safe, effective

An investigational compound for the treatment of dry eye disease consisting of a proprietary formulation of sodium hyaluronate ophthalmic solution 0.18% (Vismed, Lantibio Inc.) was shown to be safe and effective in a multicenter phase III trial conducted in the United States. A new drug application has been filed for the solution, which is already marketed in parts of Europe and Asia as a viscoelastic lubricant eye drop.

Osmometer comparison shows newer technology allows faster, easier measurement

A head-to-head comparison of an older nanoliter osmometer (Clifton Technical Physics) and a newer osmometer (OcuSense) shows that both devices are effective in measuring tear osmolarity and produce comparable measurements. The newer device has great potential for office clinical use, because readings can be taken very easily and quickly by a non-trained individual, according to one doctor.

Intraductal meibomian gland probing reduces inflammation quickly, results show

A new technique of intraductal meibomian gland probing using disposable cannulas of various lengths appears highly effective in providing quick and lasting relief from inflammatory symptoms of obstructive meibomian gland disease.

Eye drop formulation found effective for post-LASIK dry eye

Optive Sensitive (Allergan) was safe and effective for the management of dry eye signs and symptoms after LASIK surgery and may have some incremental benefits over standard tear management.
