WE OCULOPLASTIC surgeons are mechanics at heart. We view the eyelid as a complex machine formed of tendons and pulleys, and our surgical procedures revolve around the shortening, lengthening, and tightening of different tissue constituents. The limitations of our current surgical techniques do not revolve around mechanical factors, which we can control with modern instrumentation, as much as they relate to our lack of a complete understanding of biology and our limited ability to control it. These limitations become apparent when analyzing the alloplastic materials used in oculoplastic surgery.
