Infrared thermography for the analysis of ocular surface temperature after phacoemulsification

ABSTRACT Purpose: In this study, we present our observations on changes in the surface temperature of the cornea, eye, and orbital cavity after cataract surgery. Methods: A total of 39 patients who underwent cataract surgery based on phacoemulsification were enrolled. Temperature was measured at the center of the cornea, on the eye surface, and in orbital cavities using the FLIR T640 thermal imaging camera at days 1, 14, and 28 after cataract phacoemulsification and compared with preoperative baseline values. Results: The mean value of ocular surface temperature of the orbital cavity 14 days after cataract surgery was significantly different compared with the preoperative temperature (p£0.05). Temperature of the investigated areas showed a reduction, with the greatest decrease on day 14 after surgery, followed by an increase on day 28 after surgery, which was comparable to the temperature measured prior to surgery. Conclusions: The reduction in ocular surface temperature toward the end of post-cataract surgery follow-up may be associated with increased instability of the tear film after phacoemulsification. Therefore, patient awareness regarding the possibility of clinical symptoms of dry eye syndrome during the first month after surgery should be part of clinical management of cataract surgery. Ocular surface temperature did not increase after cataract surgery, suggesting the absence of significant inflammation, and the temperature about 1 month after cataract surgery was comparable to that before surgery. Nevertheless, the negative correlation between age and ocular surface temperature should be of concern in the elderly.
