~ Clinical Studies ~

OPHTECS CORPORATION conducted a 3-month, double-masked, bilateral, randomized, clinical trial to compare the clinical performance of two rigid gas permeable (RGP) multi-purpose solutions and test whether cleadew GP Hydra one (Test) is substantially equivalent to Boston SIMPLUS (Control) when used with a rub and rinse regimen.

One-hundred and one (101) existing RGP contact lens wearers were enrolled onto the study, 97 of whom were dispensed study lenses. In total, 66 were randomized to the test group and 31 to the control group. Of the 97 dispensed subjects, 70% were female. Mean age at baseline was 63.5 ±9.4 years (range: 41–82 years). The mean spherical refraction was -3.69 D (range: 6.00 to -10.00 D) and mean refractive cylinder was -0.78 D (range: 0 to -2.00 D).

In total, 91 subjects (94%, 91/97) completed the study: 61 (92%) test subjects and 30 (97%) control subjects.

The following conclusions are supported by the findings of this study:

The incidence of ocular adverse events with Cleadew GP Hydra one was non-inferior to that with Boston SIMPLUS™.
The average grades for slip-lamp assessments of limbal hyperemia, bulbar hyperemia, corneal vascularization, and corneal staining with Cleadew GP Hydra one were non-inferior to those with Boston SIMPLUS™.
The average grades for subjective comfort, lens deposits, and wettability with Cleadew GP Hydra one were non-inferior to those with Boston SIMPLUS™.

The results of the study support a substantial equivalence determination.

VIII. CONCLUSIONS

Substantial Equivalence

Based on the results of the clinical and non-clinical testing presented in this Premarket Notification, the cleadew GP hydra one is as safe and effective as the predicate device when used in accordance with the labeled directions for use and for the proposed indication.
