Evaluation of Effectiveness and Safety of Intense Pulsed Light Treatment for Chalazion

Evaluation of Effectiveness and Safety of Intense Pulsed Light Treatment for Chalazion

To study the effectiveness and safety of IPL treatment for Chalazion

The study aims to evaluate the effectiveness and safety of IPL therapy for the treatment of chalazion. The effect of IPL on chalazion will be examined in a masked randomized controlled study. Subjects in the study arm will be treated with IPL, while subjects in the control arm will be treated with sham IPL. A significant difference in the outcomes of the two arms will provide support for a genuine contribution of the IPL treatment
