摘要： Se describen lentes de contacto de hidrogel de silicona que tienen niveles oftálmicamente aceptables de pérdida de energía. Los lentes se derivan de una composición polimerizable que incluye un primer monómero de siloxano representado por la fórmula (1): (ver Fórmula) en donde m de la fórmula (1) representa un número entero de 3 a 10, n de fórmula (1) representa un número entero de 1 a 10, R1 de la fórmula (1) es un grupo alquilo que tiene de 1 a 4 átomos de carbono y cada R2 de la fórmula (1) es independientemente cualquiera de un átomo de hidrógeno o un grupo metilo; los lentes también incluyen unidades derivadas de un segundo monómero de siloxano que es un polidimetilsiloxano terminado en extremo metacrilato de extremo dual que tiene un peso molecular promedio numérico de por lo menos 7,000 daltons. La pérdida de energía promedio de los lentes de contacto de hidrogel de silicona es de aproximadamente 30% a aproximadamente 45% cuando los lentes están completamente hidratados. También se describen lotes de lentes de contacto de hidrogel de silicona y métodos para producir lentes de contacto de hidrogel de silicona.

摘要： Silicone hydrogel contact lenses having ophthalmically acceptable levels of energy loss are described. The lenses are derived from a polymerizable composition including a first siloxane monomer represented by formula (1): wherein m of formula (1) represents one integer from 3 to 10, n of formula (1) represents one integer from 1 to 10, R1 of formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each R2 of formula (1) is independently either a hydrogen atom or a methyl group; the lenses also include units derived from a second siloxane monomer which is a dual-end methacrylate end-capped polydimethylsiloxane having a number average molecular weight of at least 7,000 daltons. The average energy loss of the silicone hydrogel contact lenses is from about 30% to about 45% when the lenses are fully hydrated. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.

摘要： DEMOLDING AIDS FOR SILICONE HYDROGELS AND RELATED METHODS 5 COMPOSITIONS AND METHODS FOR IMPROVING DEMOLDING POLAR RESIN MOLDS USED IN THE PRODUCTION OF SILICONE HYDROGEL MATERIALS ARE DESCRIBED. THE PRESENT COMPOSITIONS AND METHODS INCLUDE THE USE OF ONE OR MORE REACTIVE DEMOLDING AGENTS. THE REACTIVE DEMOLDING AGENTS REACT WITH COMPONENTS OF A POLYMERIZATION MIXTURE TO PRODUCE A POLYMERIZED SILICONE HYDROGEL DEVICE CONTAINING A REACTANT LO PRODUCT OF THE DEMOLDING AGENT AND THE OTHER COMPONENTS OF THE POLYMERIZATION MIXTURE. POLAR RESIN MOLDS USED DURING THE POLYMERIZATION OF THE POLYMERIZATION MIXTURE ARE MORE EASILY SEPARATED THAN SUBSTANTIALLY IDENTICAL MOLDS USED IN THE POLYMERIZATION OF A SUBSTANTIALLY IDENTICAL MATERIAL WITHOUT A REACTIVE DEMOLDING AGENT. THE PRESENT COMPOSITIONS AND METHODS MAY BE USED IN THE MANUFACTURE OF 15 SILICONE HYDROGEL LENSES, SUCH AS CONTACT LENSES. THE DEMOLDING AIDS MAY ALSO BE USEFUL AS DELENSING AIDS.
