Methods: Sixty eyes of 60 patients who underwent pars plana vitrectomy and intraocular silicone oil tamponade were enrolled in this prospective study. Central corneal temperatures were measured by handheld NCIT from the corneal surface and these values were compared with the corneal temperatures of the contralateral eyes of the same subjects.

Results: Statistically significant difference was observed between silicone oil filled eye and contralateral nonoperated eye (p<0.001). There was a significant correlation between temperature of silicone oil filled eye and contralateral eye (p<0.001). Statistically signifi cant negative correlation was observed between postoperative period and temperature of silicone oil filled eye (p=0.003). The mean values of temperatures were found to be higher statistically in phakic eyes compared with pseudophakic ones in both silicone oil filled and contralateral eye group (p=0.010, p=0.011, respectively).

Conclusion: Silicon oil and acrylic and polymethylmethacrylate lenses may affect tissue metabolism because it changes heat conduction. Heat change in tissues can be responsible for complications. Further studies are needed to confirm our results. Keywords : Corneal temperature, Infrared thermometer, Eyes with silicone oil
