Clinical Observations on Hyper II(R) Soft Contact Lens

ABSTRACT

To estimate the clinical usefulness of a newly developed soft contact lens, Hyper II(R) soft contact lens which is a product of 2-hydroxyethylmethacrylate and special cross linking agents by International Contact Lens Lab., Seoul Korea, clinical observations were carried out in 89 patients(154 eyes) during the follow up period of 3 months from April 1985 to February 1986. Excellent corrected visual acuity(over 1.0) was obtained in 134 eyes(87%). The most common subjective symptom after wearing contact lens was foreign body sensation, but this symptom had diminished during the follow up period. Twentyfour eyes discontinued wearing the lens because of lens related problems including lens deposit(11 eyes), lens lost(3 eyes), foreign body sensation(3 eyes), handling difficulty(2 eyes), lens torn (1 eyes) et al. It can be suggested that Hyper II(R) soft contact lens is clinically available with excellent improvement of visual acuity and few complications, either subjective or objective, which might influence wearing contact lens. Long-term follow up, however, might be necessary to understand and reduce the late complications of this soft contact lens.
