Universidad de Zaragoza Computational simulation of scleral buckling surgery for rhegmatogenous retinal detachment: On the effect of the band size on the myopization 2016 Access copy available to the general public Unrestricted A finite element model (FE) of the eye including cornea, sclera, crystalline lens, and ciliary body was created to analyze the influence of the silicone encircling bandwidth and the tightness degree on the myopia induced by scleral buckling (SB) procedure for rhegmatogenous retinal detachment. Intraocular pressure (IOP) was applied to the reference geometry of the FE model and then SB surgery was simulated with encircling bandwidths of 1, 2, and 2.5 mm. Different levels of tightening and three values of IOP were applied. The anterior segment resulted as unaffected by the surgery. The highest value of Cauchy stress appeared in the surroundings of the implant, whereas no increment of stress was observed either in anterior segment or in the optic nerve head. The initial IOP did not appear to play any role in the induced myopia. The wider the band, the greater the induced myopia: 0.44, 0.88, and 1.07 diopters (D) for the 1, 2, and 2.5 mm bandwidth, respectively. Therefore, patients become more myopic with a wider encircling element. The proposed simulations allow determining the effect of the bandwidth or the tightness degree on the axial lengthening, thus predicting the myopic increment caused by the encircling surgery. info:eu-repo/grantAgreement/ES/DGA/T88 info:eu-repo/grantAgreement/ES/MINECO/DPI2014-54981-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.712 2016 OPHTHALMOLOGY 35 / 59 = 0.593 2016 Q3 T2 MEDICINE, RESEARCH & EXPERIMENTAL 84 / 128 = 0.656 2016 Q3 T2 0.812 2016 Ophthalmology 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-9325-9964 Buey, M.A.D.
