DIAZ-REY, J.A.; GIRALDEZ, M.J.; GARCIA-RESUA, C.  y  YEBRA-PIMENTEL, E.. Effect of double anaesthetic colicursi® (tetracaine 0.1% and oxibuprocaine 0.4%) on central and paracentral corneal thickness. Arch Soc Esp Oftalmol [online]. 2009, vol.84, n.1, pp.23-30. ISSN 0365-6691.

Objective: To study the effect of 1 drop of combined topical anaesthesia (tetracaine 0.1% and oxybuprocaine 0.4%) on central corneal thickness (CCT) values and at 2.5 mm from the corneal centre in nasal, temporal, superior and inferior hemi meridians, monitored by Orbscan over a period of 16 minutes. Materials and methods: The corneal thickness of 12 right eyes of 12 young healthy men was determined using the Orbscan Topography System. Values were determined at the centre and paracentral regions 2.5 mm from the centre every 2 minutes for 16 minutes before and after the administration of 1 drop of double anaesthetic Colircusi® which contains tetracaine 0.1% and oxybuprocaine 0.4%. Results: There was no obvious trend of central and paracentral corneal thickness value change before and after administration of Colircusi® (paired ANOVA, p>0.05). Although corneal thickness variation was not statistically significant, higher differences were observed at the 6 minute time-point for CCT and at 8 minutes for nasal paracentral corneal thickness. Conclusions: One drop of double anaesthetic Colircusi® with tetracaine 0.1% and oxibuprocaine 0.4% does not produce any significant change in central corneal thickness or in paracentral regions 2.5 mm from the centre (nasal, temporal, superior and inferior hemi meridians).
