Light scatter on the surface of AcrySof? intraocular lenses: Part I. Analysis of lenses retrieved from pseudophakic postmortem human eyes

摘要

■ BACKGROUND AND OBJECTIVE: To investigate the cause of light scatter measured on the surface of AcrySof intraocular lenses (Alcon Laboratories, Inc., Fort Worth, TX) retrieved from pseudophakic post-mortem human eyes. ■ MATERIALS AND METHODS: Ten intraocular lenses (Alcon AcrySof Model MA60BM) were retrieved postmortem and analyzed for light scatter before and after removal of surface-bound biofilms. ■ RESULTS: Six of the 10 lenses exhibited light scatter that was clearly above baseline levels. In these 6 lenses, both peak and average pixel density were reduced by approximately 80% after surface cleaning. ■ CONCLUSION: The current study demonstrates that a coating deposited in vivo on the lens surface is responsible for the light scatter observed when incident light is applied.
