Table_1_Therapeutic efficacy of optimal pulse technology in the treatment of chalazions.DOC
To evaluate the efficacy of optimized pulse technology in treating chalazia.
MethodsProspective before-after study. All patients received two sessions of optimal pulse technology (OPT) with an interval of 1 week. The first visit was before treatment and the patients underwent 2 treatment sessions with a 1-week interval. The non-invasive tear breakup time (NIBUT), corneal fluorescein staining (CFS) score, Schirmer’s test I without anesthesia, conjunctival hyperemia, and meibomian gland area were compared before and after treatment, and the related factors of curative effect were analyzed.
Results23 patients (23 eyes) with chalazia were included. All patients received two sessions of OPT treatment at 1-week intervals. Following the first OPT treatment, a reduction in the chalazion size was observed in 17 patients (73.91%). One patient was completely cured, and 1 patient had an increase in the diameter of the chalazion. The meibomian gland area increased significantly compared to before treatment (p = 0.023). Compared with baseline, the conjunctival congestion and ST decreased, NIBUT increased, and there was no statistical difference. After the second treatment, the chalazion size decreased in 21 cases, and 3 patients were cured. A significant increase in the meibomian gland area compared with the baseline area (p < 0.001). Additionally, conjunctival congestion decreased significantly. After two sessions, the Schirmer test exhibited a decrease, and NIBUT increased, although these changes did not reach statistical significance. The curative effect was unrelated to sex, age, first onset, single disease, and other factors.
ConclusionAfter treatment, the diameter of chalazions was reduced in 91.3% of the patients, and the area of the meibomian gland was significantly increased compared with that before treatment, which suggested that 2 OPT treatments at an interval of 1 week can improve the signs of adult patients in the non-acute infectious stage with chalazia.
