Corneal Damage Thresholds for Infrared Laser Exposure: Empirical Data, Model Predictions, and Safety Standards.
Abstract
Experimental damage threshold data for corneal injury from infrared lasers are compared with thermal model predictions of temperature rise, lesion radius, and damage threshold using several damage criteria. The functional dependence of the threshold exposure upon damage end-point, damage criteria, absorption coefficient, beam radius, exposure duration, and damage site is determined. Experimental and predicted thresholds are compared to the ANSI Z136.1-1976 laser safety standard. Similar analysis with the thermal model for applications such as photokeratoplasty or corneal and lenticular spectroscopy can yield alternative approaches to either maximize or avoid thermal effects often inherent in such research.
