The use of polymers in the treatment of retinal detachment: current trends and future perspectives
Full text linkProcedures for the treatment of retinal detachment and related conditions have been successfully improved upon in recent years thanks to the advent of new therapies and biomaterials. This review, after giving an overview on eye structure and function, focuses on the treatment of retinal detachment and examines the role and features of the materials used in vitreoretinal surgery, emphasizing scleral buckling and short-term/long-term vitreous tamponade. Specifically, the limitations of existing biomaterials are underlined, based on experimental studies and with particular reference to cells/material interactions. Finally, current and future trends of biomaterials’ research in the field of vitreoretinal surgery are considered and discussed
Mechanical characterization of 45S5 bioactive glass-derived scaffolds
No full textThe mechanical reliability of 45S5 bioactive glass-derived scaffolds was quantified, for the first time, by determining the Weibull modulus (m) in compressive loading mode. The scaffolds were fabricated by sponge replication followed by sinter-crystallization (main crystalline phase Na2CaSi2O6) and exhibited a trabecular pore-strut 3D architecture. The Weibull modulus (m = 6) was higher than most of those reported in the literature for bioactive glass and ceramic scaffolds. The compressive strength was found dependent on porosity according to a power-law relationship. The mechanical properties and bone-like macroporous structure of these glass–ceramic scaffolds show great promise for use in bone repair applications
