Lens safety study with Picumast dihydrochloride--a double masked study using the Scheimpflug method.
A double-masked study was performed to investigate a possible side effect of the antiallergic substance Picumast dihydrochloride on lens transparency. 372 patients with Picumast dihydrochloride- or Ketotifen-treatment regularly underwent ophthalmologic examinations and Scheimpflug photography of the anterior eye segment. Results of slitlamp examinations as well as microdensitometric analyzes of the film negatives after one year treatment did not reveal any evidence that Picumast dihydrochloride compromised lens transparency in humans.
