Low-level laser therapy combined with scleral graft transplantation in the treatment of contracted socket: a clinical study.

Objective: To analyse the efficacy of the therapeutic use of low-level laser therapy (LLLT) on the tissue repair process of allogeneic scleral grafts in patients with contracted sockets by analysing the speed of graft vascularisation and fornice depth of contraction percentage.

Methods: A retrospective chart review was performed from April 2015 to April 2021 including 39patients with socket contraction. Allogeneic scleral grafts were used to repair the sockets in all patients.

Comparison of the cutaneous orbicularis oculi excision treatment with the inferior eyelid margin fixation treatment for congenital lower eyelid entropion.

Purpose: To modify the traditional surgical approach to treat patients diagnosed with congenital lower eyelid entropion using inferior eyelid margin fixation of the orbicularis eyelid muscle.

Methods: Ninety-six participants (180 eyes) with congenital lower eyelid entropion diagnosed between January 2019 and April 2021 were included in this study. The patients were divided into Group A (cutaneous orbicularis oculi excision treatment) and Group B (inferior eyelid margin fixation treatment).

Clinical observation on healing of tarsal plate defect after reconstruction with xenogeneic acellular dermal matrix.

Objective: To evaluate the safety, function, and cosmetic outcome of eyelid reconstruction using a xenogeneic acellular dermal matrix as a tarsal plate replacement in the repair of 50 to 100% eyelid defects following excision of large malignant tumours.

Methods: A retrospective, non-comparative, interventional study of 21 eyes was performed over 26 months. Fourteen patients were female and seven were male.

Low-level laser therapy induces human umbilical vascular endothelial cell proliferation, migration and tube formation through activating the PI3K/Akt signaling pathway.

Low-level laser therapy (LLLT) has been recognized as a light therapy that may be used for tissue regeneration, inflammation reduction, and pain relief. We intended to evaluate the effects of LLLT on the proliferation, migration, and tube formation of HUVECs as well as their related mechanisms. HUVECs were exposed to laser irradiation under different laser parameters (irradiation dose, interval and power intensity) in order to choose the optimal parameters, which were determined by the increase in proliferation of HUVECs as follows: irradiation dose of 4.
