Application of tacrolimus 0.03% dermatologic ointment into the lower fornix seems to constitute an interesting alternative treatment for atopic keratoconjunctivitis that is refractory to traditional treatment.

Purpose To determinate the relatioship between corneal aberration and a biomechanical parameter: the corneal hysteresis. Methods 122 eyes of 61 patients were included in a prospective and transversal study. Range of age was between 18 and 60 years. The following measurements were realised: Corneal topography with KERATRON (Optikon) to obtain the root mean square (RMS) of corneal aberration and measurement with Ocular Response Analyzer (ORA) (Reichert) to obtain the Corneal Hysteresis (CH). The correlation between RMS – CH was calculated by SPSS 12.0 (Statistical Package for the Social Sciences, Chicago, IL) using the correlation of Pearson for quantitative and independent variables. Results No statistically significant correlation could be demonstrated between RMS and CH analysing both eyes as well as left and right eyes separately. Conclusion The relationship between CH and each Zernike coefficient separately could be analysed as other studies found a correlation between intraocular pressure and high order aberrations. The importance of corneal biomechanical parameters like CH and CRF, values determined by the ORA, is not well defined yet; however the influence of these factors not only on intraocular pressure but also on corneal pathologies should be considered.
