Helmy H, et al. - Via this prospective clinical case study, researchers sought to establish a simple correction formula for the calculation of intraocular pressure (IOP) in post laser-assisted corneal refractive surgery (LASIK) myopic patients. Three hundred eyes of 150 patients with myopia and myopic astigmatism as a refractive error who underwent LASIK were assessed in this work. Patients aged between 18 to 50 (mean ± SD 34.78± 8.8) years. Corneal refractive surgery with LASIK led to changes in IOP measurements. The analysis revealed a positive correlation between corneal thickness and IOP difference among patients both preoperatively and postoperatively. Ablation depth was positively correlated with IOP change. The established correction formula for IOP was: Real IOP = 4+0.7(preoperative IOP)− 0.3(ablation depth). They suggest the corrected formula as a good option for the precise calculation of post-LASIK IOP.
