摘要: Abstract Objective To investigate the effects of encircling scleral buckle (SB) on corneal biomechanical properties cornea and its morphological parameters. Methods We prospectively examined twelve eyes diagnosed with vitreous haemorrhage undergoing pars plana vitrectomy (PPV), fifteen combined PPV (PPV/SB) for repair rhegmatogenous retinal detachment (RRD). Corneal properties, including hysteresis (CH) resistance factor (CRF), were measured an Ocular Response Analyser (ORA) before 1-month postoperatively. The ORA also determined values intraocular pressure (IOPg) compensated IOP (IOPcc). Finally, four parameters Orbscan II topographer (Orbtek, Inc.): mean power, thinnest point (μm), anterior chamber depth (ACD). Results CH decreased significantly from 10.2 ± 1.7 mmHg to 7.6 ± 1.1 mmHg after PPV/SB (p = 0.003), but not alone (9.8 ± 3.2 mmHg vs 11.6 ± 2.7 mmHg, p = 0.465). CRF did change surgery in both groups. IOPg IOPcc increased group (p = 0.019 p = 0.010, respectively) (p = 0.715 p = 0.273, respectively). Unlike group, higher than (p = 0.001) (p = 0.003) IOPcc. Neither nor showed any significant changes (p > 0.05). Conclusions SB leads a without altering It may cause underestimation error measurement. be less invasive surgical approach noncomplex RRD PPV/SB.
