Purpose: In this study comparisons have been made between intraocular pressure measurement (using a noncontact tonometer) with and without soft contact lenses on the eye. The influence of lenses of different water content and central thickness was examined.
Materials and Methods: Intraocular pressure was measured in right and left eyes of 100 healthy people who can use contact lenses, using a noncontact tonometer. Alphafilcon A soft contact lenses (water content %66, central thickness 0,1-0,2 mm) were placed on right eyes. Polymacon soft contact lenses (water content %38,6, central thicknes 0,035-0,094 mm) were placed on left eyes. Noncontact tonometer were used to remeasure the intraocular pressure through the contact lenses.
Results: The average intraocular pressure without the contact lens was not statistically different from the intraocular pressure with the contact lens. Lens central thickness and water content did not significantly affect the values of intraocular pressure measured with noncontact tonometer.
Conclusions: Intraocular measurements through soft contact lenses can accurately be made on patients who require application of soft contact lens without disturbing the position of the contact lens.Keywords: Noncontact tonometer, Contact lens, Intraocular pressureTurkiye Klinikleri J Ophthalmol 2001, 10:187-189
