Abstract

This investigation is carried out on two groups of patients with corpus alienum corneae. In every group are included 40 patients (40 eyes). For the first group standard treatment is applied after extraction of the corpus alienum corneae using antibiotic drugs (Oftaquix®) and epithelizing gel (Corneregel). First group is used as a control. For the second group of patients immediately after extraction of the corpus alienum corneae, eyes are irradiated for 3 minutes with He-Ne laser (Mediray 04, Optella Ltd., Sofia, Bulgaria) at emission wavelength at 632 nm and power density 0.1 mW/cm2. Second group of eyes is treated with the same drugs as the control group. We observed epithelisation of the damaged cornea in the first group - after 24 hours, and in the laser-irradiated group of eyes significant epithelisation is pronounced the 10th hour after irradiation. Epithelization is proved by fluorescein reaction to detect the eye cornea recovery. The patient eyes of the both groups were investigated under bio-microscope in cobalt-blue illumination. For irradiated eyes by LLLT, we have found that the healing period is shortened significantly by 42 % (p<0,001). Our results revealed that LLLT application is appropriate and perspective for recovery therapy after corpus alienum corneae extraction.
