A novel preservative-free multi-ingredient formulation of artificial tears showed comparable efficacy but superior benefit in uncorrected vision in the management of dry eye after LASIK vs. standard carboxymethylcellulose 0.5% treatment.
A total of 125 patients in 13 clinics in Canada and one clinic in Australia who completed the study received either the new formulation (Refresh Optive Fusion Sensitive, Allergan), which contains carboxymethylcellulose 0.5%, hyaluronic acid 0.1% and organic osmolytes (CMC-HA), or the standard treatment (Refresh Plus, Allergan) to manage post-LASIK dry eye
