Cost Analysis of Scleral Buckle and Pars Plana Vitrectomy for Retinal Detachment Surgery
No full textÁlvaro J Rallo-López,1 Rafael Martínez-Costa Pérez2 1Department of Ophthalmology, Clínica Baviera, Valencia, Spain; 2Department of Ophthalmology – Retina and Vitreous, Hospital Universitario y Politécnico La Fe, Valencia, SpainCorrespondence: Álvaro J Rallo-López, Email [email protected] and Objective: To compare the cost and utility of scleral buckle (SB) and pars plana vitrectomy (PPV) techniques for repairing moderately complex rhegmatogenous retinal detachment (RRD).Patients, Materials, and Methods: A cost-utility analysis was conducted using data from the Primary Retinal Detachment Outcomes Study (PRO) and a study conducted by the author. Total costs, patient utility over a lifetime, and cost per quality-adjusted life year (QALY) were calculated for each surgical procedure.Results: The cost of scleral buckle surgery was € 287.93, with an estimated lifetime QALY of 7.49. Costs per QALY were € 38.44. According to the PRO study and Belin et al, total costs were $5975, with a lifetime QALY of 5.4 and costs per QALY of $1106. The cost of pars plana vitrectomy (PPV) was € 1468.26, with an estimated lifetime QALY of 6.84 and costs per QALY of € 214.65. Based on the PRO study and Belin et al, total costs were $8125, with a lifetime QALY of 4.7 and costs per QALY of $2196.Conclusion: Repairing moderately complex RRD presents a highly cost-effective profile for both SB and PPV techniques, well below recommended QALY thresholds. SB demonstrated a slightly more favorable profile compared to PPV.Keywords: retinal detachment, pars plana vitrectomy, scleral buckle, cost-utility analysis, QAL
On the velocity of buckle propagation in a beam on a nonlinear elastic-foundation
No full textThe paper revisits a simple beam model used by Chater et al. (1983, Proc. IUTAM Symp. Collapse, Cambridge University Press) to examine the dynamics of propagating buckles on it. It was found that, if a buckle is initiated at a constant pressure higher than the propagation pressure of the model (P-p), the buckle accelerates and gradually reaches a constant velocity which depends upon the pressure, while if it is initiated at P-p, the buckle propagates at a velocity which depends upon the initial imperfection. The causes for the difference are also investigated
