Abstract
1.1.Introduction: The use of intense pulsed light (IPL) increased in recent years. This study aimed to identify the types and degrees of eye injury caused by IPL in ‘’ex vivo’’ porcine eye, correlating the distance from the shooting location of the ocular region, power and pulse duration used. 1.2.Methods: Experimental study. Intense pulsed light (IPL) was applied in five different treatment strategies (7J/5ms, 9 J/12ms, 10J/18 ms, 11J/26ms and 12J/34 ms) with corneal thickness evaluation pre and post procedure and classification of degree of eye injury observed in biomicroscopy slit lamp in the phase after the procedure. 1.3.Results: There was no change in pachymetry in the group of lower power and frequency - Group 1 (7J/5 ms), but from 9J/12 ms (groups 2, 3, 4 and 5) all groups presented reduction of corneal thickness. The biomicroscopy analysis in slit lamp showed that inferior keratitis was observed a greater number of eyes subjected to intense pulsed light procedure with minor powers (7 and 9J) and iris lesion were observed a greater number of eyes subjected to light procedure intense pulsed with greater powers (12J). 1.4.Conclusion: Ocular adverse effects were observed in all strategies of the intense light pulse procedure in porcine eye. The intraocular effects such as iris lesions were more evident in treatments with higher powers. Change of corneal thickness was observed with intense pulsed light from 9J and 12 ms. Because of the lesions observed in the evaluation after the procedure we corroborate the recommendation of using scleral lenses, possibly made of stainless steel, to dissipate the energy of the IPL when ophthalmic procedures or esthetic procedure near the eyeball margin.
