| To determine the influence of corneal thickness on intraocular pressure a measurement on biomechanical eye model was build using a CAD-type software. The model assumes an average corneal thickness of 527 μm and pressure prevailing in the anterior chamber of the eye equal to 16 mm Hg. Then, assuming a constant thickness of the cornea, a curve was built depicting changes in the corneal topography due to the action of the air puff for various intraocular pressure values. The pressure ranged from 8 to 24 mm Hg. Then, for a constant intraocular pressure equal to 16 mm Hg, the corneal thickness in the model was changed from 400 to 700, every 25 μm, and such a modeled eye was subjected to the same air puff. From the comparison of deformations resulting from the change of thickness with changes resulting from different pressures at the average corneal thickness, the range of distortion of the intraocular pressure measurement was obtained, depending on the thickness of the cornea. |
