Resumen

HERNANDEZ-VERDEJO, J.L.; BOLIVAR-DE-MIGUEL, G.; ROMAN-GUINDO, J.M.  y  TEUS-GUEZALA, M.A.. An experimental model to measure real intraocular pressure (IOP) during LASIK. Arch Soc Esp Oftalmol [online]. 2007, vol.82, n.9, pp.541-545. ISSN 0365-6691.

Purpose: To design a model to measure real IOP during lasik in pig eyes. Methods: A reusable blood pressure transducer was used. Each eye was placed on a stand with sufficient support for the surgical procedure. The globes were inflated with 5% glucosated solution through the optic nerve to attain an IOP of 10-20 mmHg. A 27-gauge catheter was then inserted from the pars plana to the anterior chamber cavity. Real IOP was transmitted via the catheter liquid column to an external sensor. A suction ring was applied and a flap was created. During the procedure, IOP was registered with the ML110 Bridge Amplifier connected to a baro transducer. Results: Values of real IOP were measured in freshly enucleated pig eyes during the lasik procedure. The model was able to instantaneously register the changes in IOP induced by the application of a suction ring and the creation of a flap in the pig eyes with good reproducibility. At the end of the procedure the IOP values remained stable. Conclusions: We have developed an experimental model to observe the course of suctioning and changes in IOP simultaneously. This model seems to be accurate in obtaining IOP values from the anterior chamber cavity during lasik.
