A method of cross-linking collagen present in a collagenous tissue comprising contacting the collagenous tissue with an amount of a formaldehyde releasing agent effective to crosslink the collagen is provided. A method of inhibiting loss of structural integrity of a collagenous tissue during transplantation-related transport comprising contacting the collagenous tissue with an amount of a formaldehyde releasing agent effective to inhibit loss of structural integrity of the collagenous tissue is also provided. A composition for ophthalmic administration comprising a formaldehyde releasing agent, sodium bicarbonate, and ophthalmically suitable carriers or excipients is also provided. Finally, a method of altering the refractive power of a cornea comprising contacting the cornea with a formaldehyde releasing agent so as to effect cross-linking in the cornea and thereby alter the refractive power of the cornea is provided.
本发明提供了一种交联存在于胶原组织中的
胶原蛋白的方法,包括将胶原组织与一定量的
甲醛释放剂接触,以有效交联
胶原蛋白。还提供了一种抑制胶原组织在移植相关运输过程中丧失结构完整性的方法,该方法包括将胶原组织与一定量的
甲醛释放剂接触,
甲醛释放剂能有效抑制胶原组织丧失结构完整性。还提供了一种用于
眼科用药的组合物,该组合物由
甲醛释放剂、
碳酸氢钠和眼科适用的载体或赋形剂组成。最后,还提供了一种改变角膜屈光力的方法,该方法包括将角膜与
甲醛释放剂接触,使角膜发生交联,从而改变角膜的屈光力。
