ABSTRACT
INTRODUCTION:
Femtosecond laser is a revolutionary, innovative treatment method used in cataract surgery.AIM:
To evaluate free radical quantity in the anterior chamber of the eye, during femtosecond laser assisted capsulotomy, in a porcine eye model.METHOD:
Seventy fresh porcine eyes were collected within 2 hours post mortem, were transported at 4 ºC and treated within 7 hours. Thirty-five eyes were used as control and 35 as femtosecond laser assisted capsulotomy group. A simple luminol-dependent chemiluminescence method was used to measure the total scavenger capacity in the aqueous humour, as an indicator of free radical production. The emitted photons were expressed in relative light unit %.RESULTS:
The relative light unit % was lower in the control group (median 1%, interquartile range [0.4-3%]) than in the femtosecond laser assisted capsulotomy group (median 4.4%, interquartile range [1.5%-21%]) (p = 0.01).CONCLUSIONS:
Femtosecond laser assisted capsulotomy decreases the antioxidant defense of the anterior chamber, which refers to a significant free radical production during femtosecond laser assisted capsulotomy. Orv. Hetil., 2016, 157(47), 1880-1883.Palabras clave
