Clinical Experiences of Extended wear Soft Contact Lens: Permalens(Perfilcon-A): in Aphakic Patients

ABSTRACT

Extended wear soft contact lens will be the fascinating idea among the contact lens wearers in near future. A contact lens that is to be left on the eye surface during periods of sleep must achieve a degree of ocular compatibilities not previously encountered in contact lens practice. In this paper I report the clinical studies of Permalens, that is made by Global Vision, England, in 6 aphakic patients. During the 4 months periods of follow-up studies, all patients ara using their lenses very comfortably and no specific complications are found until now.
