A controlled comparison of two therapeutic soft lenses in a clinical model.

Laboratory data of a new, highly hydrated contact lens (Weicon 72) indicated that it might be therapeutically superior to the known Weicon 38. The great variability of therapeutic contact lens cases, however, makes a sound clinical evaluation difficult. Therefore the two lenses were tested in a clinical model using patients with traumatic superficial corneal defects. The results were statistically significant, the Weicon 72 proving to be superior to the Weicon 38.
