Description
Purpose: To evaluate the effectiveness of Diclofenac Sodium .1% (Voltaren) in relieving the foreign body sensation, itching, tearing and overall discomfort during the first three days of Rigid gas permeable lens adaptation.
Setting: Michigan College of Optometry, Ferris State University, Big Rapids, MI, USA.
Methods: A double-blind, placebo controlled, prospective, pilot study, comprised of tour patients (8 eyes) was conducted. The patients were to wear the RGPlenses six hours each day for 3 days. During this time, the patient was to instill drops from the appropriate bottle into each eye four times per day. One eye would receive drops from a bottle which contained Voltaren the other eye would receive drops from a bottle which contained the Voltaren vehicle. Three surveys were completed each day during the study to subjectively evaluate the patients level of itching, tearing, foreign body sensation and overall discomfort. The
results were analyzed to determine any differences between the two eyes.
Results: There were no significant differences in discomfort between the eyes
treated with Voltaren and the eyes treated with the Voltaren vehicle. Conclusion: These findings suggest that Voltaren is ineffective at relieving the discomfort during rigid gas permeable lens adaptation.
