A clinical study published in the Journal of Ophthalmology concludes that Intraocular Pressure (IOP) measured with Transpalpebral DIATON tonometry before and after Laser In Situ Keratomileusis Refractive Surgery is not influenced by the treatment.
Purpose of the study was to compare the intraocular pressure (IOP) before and after Laser In Situ Keratomileusis (LASIK), measured by Diaton, Perkins, and noncontact air pulse tonometers.
Methods. Fifty-seven patients with a mean age of 34.88 were scheduled for myopia LASIK treatment. Spherical equivalent refraction (SER), corneal curvature (K), and central corneal thickness (CCT) and superior corneal thickness (SCT) were obtained before and after LASIK surgery. IOP values before and after surgery were measured using Diaton, Perkins, and noncontact air pulse tonometers.
Results. The IOP values before and after LASIK surgery using Perkins tonometer and air tonometers were statistically significant (𝑝 < 0.05). However, no significant differences were found (𝑝 > 0.05) for IOP values measured with Diaton tonometer. CCT decreases significantly after surgery (𝑝 < 0.05) but no statistical differences were found in SCT (𝑝 = 0.08). Correlations between pre- and postsurgery were found for all tonometers used, with 𝑝 = 0.001 and 𝑟 = 0.434 for the air pulse tonometer, 𝑝 = 0.008 and 𝑟 = 0.355 for Perkins, and 𝑝 < 0.001 and 𝑟 = 0.637 for Diaton.
Conclusion. Transpalpebral tonometry may be useful for measuring postsurgery IOP after myopic LASIK ablation because this technique is not influenced by the treatment.
