Abstract
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

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 2.5mm 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. [--]
