The authors propose a variation of the technique for making ocular protheses for large ophthalmic cavities introducing an expanded polystyrene (styrofoam) to the acrylic resin at the time of making the prosthetic sclera, aiming at reducing the weight of the prosthesis and thus improving mobility and aesthetics. This study compares the differences in weight, absorption of water and resistance to rupture by hydrostatic pressure of the pieces made of acrylic resin, chemically activated, heat activated and cross-linked by the proposed technique and by the technique for hollow ocular prothesis. The proposed technique presents advantages in manufacturing time and handling of the material.
作者提出了一种用于制作大眼眶眼假体的技术变体，即在制作假体巩膜时将发泡聚苯乙烯（泡沫塑料）引入丙烯酸树脂中，旨在减轻假体重量，从而提高其活动性和美观性。本研究比较了通过所提出的技术以及空心眼假体技术，用化学活化、热活化和交联的丙烯酸树脂制成的部件在重量、吸水性和耐静水压力破裂性方面的差异。所提出的技术在制造时间和材料处理方面具有优势。
