The Impact of Contact Lens Wear on Intraocular Pressure Measurements Utilizing the iCare Tonometer

Background : This research study aims to evaluate the effect of contact
lenses have on intraocular pressure measurements using the iCare
Tonometer. Methods: Intraocular pressure was measured six times in 50 eyes of healthy optometry students using the iCare Tonometer. The first three readings were taken without a contact lens on the eye. The second three readings were taken after a -2.00 diopter (D) Focus Dailies contact lens was inserted and allowed to settle on the eye for three minutes.
Results : There were no statistical or clinically significant difference found in the intraocular pressure measurements taken with the iCare Tonometer on eyes with -2.00 D contact lenses inserted compared to those eyes without the lenses. Conclusion: The iCare Tonometer is a quick, reliable method of evaluating intraocular pressure in contact lens wearers with mild amounts of myopia
