We are passionate about preservative free

Preser­v­a­tives are increas­ing­ly recog­nised as hav­ing a neg­a­tive impact on ocu­lar struc­tures even in con­cen­tra­tions as low as 0.005%¹. Patients with Dry Eye Dis­ease (DED), par­tic­u­lar­ly those who require fre­quent use of lubri­cants or oth­er top­i­cal ther­a­pies, should avoid ocu­lar lubri­cants that con­tain Ben­za­lko­ni­um chlo­ride (BAK)².

By devel­op­ing treat­ments, pro­vid­ing infor­ma­tion, and shar­ing knowl­edge with spe­cial­ists around the world, Théa enable every­one to keep their eyes wide open’, our com­pa­ny mes­sage. We’re com­mit­ted to cre­at­ing open­ness and dis­cus­sion about the key issues in eye care, espe­cial­ly the use of preservatives.
