Abstract
This article explores the burgeoning role of cold atmospheric plasma (CAP) in ophthalmology. The versatile nature of CAP has transformed various facets of eye care, offering novel possibilities across different clinical domains. From sterilizing surgical instruments without compromising their integrity to effectively managing challenging corneal diseases like microbial keratitis and fungal infections, CAP has shown promising results. Moreover, its potential role in promoting corneal wound healing, facilitating corneal transplants, and enhancing outcomes in cataract surgeries deserves attention. The low-tension plasma blade (ie, the Fugo blade™, Medisurg Ltd. Norristown, PA), a controlled and precise form of CAP, has emerged as a game-changer in delicate eye surgeries. Its unmatched precision, minimal tissue damage, and surgeon-friendly nature have revolutionized ophthalmic procedures, including ptosis correction, dry eye treatment, and conjunctival cyst ablation. Despite conflicting findings on the efficacy of this technology in certain aspects, the extensive body of research on CAP underscores its potential for wider ophthalmic integration. Further investigation, including human trials, is crucial for understanding the in vivo safety profile of CAP for ophthalmic applications and optimizing its use, potentially revolutionizing ocular disease management and improving patient outcomes.

Abstract
PURPOSE To report the plasma therapy technique and its clinical outcomes in patients with benign eyelid lesions. METHODS This is a retrospective, noncomparative, interventional study. The study included 71 eyes of 66 patients who underwent plasma exeresis for benign eyelid lesions in our clinic between February 2018 and December 2022. Patient symptoms, cosmetic outcomes, and complications were evaluated. RESULTS The lesions were removed with a single plasma exeresis treatment in all patients. The mean size of the lesion at its largest part was 5.5 ± 1.2 mm (range, 3.0-8.8 mm). No complications were encountered during the procedure. The mean procedure time was 4.0 ± 0.7 minutes (range, 3-6 minutes). Postoperatively, only 3 cases (4.2%) with tarsal conjunctival extension had mild irritation symptoms such as pain, discomfort, and redness. The treated areas were fully improved cosmetically, and all patients were satisfied with the cosmetic outcomes. CONCLUSIONS The plasma therapy technique for removing benign eyelid lesions offers minimally invasive surgery, less discomfort, fast recovery, and successful anatomical and cosmetic outcomes.

[PMID: 38207054 DOI: 10.1097/ico.0000000000003464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 11/26/2023] [Indexed: 01/13/2024]
Abstract
PURPOSE The aim of this study was to compare the clinical outcomes of plasma-based conjunctivoplasty and argon laser photocoagulation techniques used in the treatment of conjunctivochalasis. METHODS The study included 119 eyes from 67 patients who underwent plasma-based conjunctivoplasty or argon laser photocoagulation for conjunctivochalasis in our clinic between February 2021 and March 2022. Group 1 included 62 eyes from 35 patients who had plasma-based conjunctivoplasty. Group 2 included 57 eyes from 32 patients who had argon laser photocoagulation. Main outcomes were patient symptoms, the degree of conjunctivochalasis, fluorescein staining score, tear breakup time, the amount of conjunctival shrinkage, and complications. RESULTS Before surgery, Group 1 had grade 1 conjunctivochalasis in 8 eyes (12.9%), grade 2 in 20 eyes (32.2%), and grade 3 in 34 eyes (54.8%). In Group 2, 9 eyes (15.7%) had grade 1, 21 eyes (36.8%) had grade 2, and 27 eyes (47.3%) had grade 3 conjunctivochalasis (P = 0.43). At the sixth postoperative month, only 2 eyes (3.2%) in Group 1 had grade 1 conjunctivochalasis, whereas the other cases (96.7%) had no conjunctivochalasis. However, Group 2 had grade 1 conjunctivochalasis in 16 eyes (28.0%), grade 2 in 21 eyes (36.8%), and grade 3 in 2 eyes (3.5%). Conjunctival shrinkage in Group 1 (5.1 ± 1.2 mm) was significantly higher than in Group 2 (3.3 ± 0.9 mm; P < 0.001). Postoperative tear breakup time in Group 1 (10.2 ± 2.1 seconds) was significantly longer than in Group 2 (8.8 ± 2.0 seconds; P < 0.001). CONCLUSIONS Plasma-based conjunctivoplasty demonstrated greater clinical improvement and efficacy than argon laser photocoagulation for the treatment of conjunctivochalasis.

Abstract
In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Abstract
Background Conjunctival nevi (CN) are common benign ocular tumors. Given their low risk of malignancy, surgical removal of nevi is primarily requested by patients. Herein, we introduce Atmospheric Low-temperature Plasma (ALTP) as a novel noninvasive method for the removal of CN. Methods A clinical case series was conducted from 2020 to 2021 at the Vision Health Ophthalmic Center in Tehran, Iran. CN in one of the eyes of seven patients was treated. In all patients, the benignity of CN was confirmed by ocular oncologists. The white handpiece of the Plexr device, which generates plasma with the lowest output, was used to apply plasma spots on the nevi. In addition, the Ocular Surface Disease Index (OSDI) questionnaire was completed by all patients before and six months after the treatment. Results In all patients, the nevi outside the limbus area completely disappeared. The mean size of pre- and post-operative nevi was 3.89×11.7 and 0.54×1.69 mm, respectively. Results of the OSDI questionnaire showed significantly lower scores after the surgery in all patients. Conclusion The ALTP method is a simple, cost-effective, and office-based surgery to remove CN safely and effectively.

The assessment of the concentration of candidate cytokines in response to conjunctival-exposure of atmospheric low-temperature plasma in an animal model. BMC Ophthalmol 2021; 21:417. [PMID: 34863132 PMCID: PMC8642870 DOI: 10.1186/s12886-021-02167-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 11/08/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Atmospheric Low-Temperature Plasma (ALTP) can be used as an effective tool in conjunctival cyst ablation, but little is known about how conjunctival ALTP-exposure affects the concentration of inflammatory mediators and also the duration of inflammatory responses. METHODS We used 8 female adult Lewis rats that were followed up in 4 groups. The right eye of each rat was selected for the test, whereas the left eye was considered as a control. The ALTP was generated and used to target 3 spots of the conjunctiva. The digital camera examinations were performed to follow-up the clinical outcomes after ALTP exposure. Tear and serum samples were isolated-at 2 days, 1 week, 1 month, and 6 months after treatment-from each rat and the concentration of candidate pro-inflammatory (i.e. IL-1α, IL-2, IL-6, IFN-γ, and TNF-α) and anti-inflammatory cytokines (i.e. IL-4 and IL-10) were measured using flow cytometry. RESULTS The external and digital camera examinations showed no ocular surface complications in all ALTP-exposed rats after 1 week. The analyses revealed that the ALTP transiently increases the concentration of pro-inflammatory cytokines-IL-1α and IL-2 in tear samples in 1 week and 2 days after exposure, respectively; no differences were observed regarding other pro- and anti-inflammatory cytokines in the tear or serum samples. CONCLUSIONS ALTP can probably be used as a minimally-invasive therapeutic method that triggers no permanent or continual inflammatory responses. The results of this study might help the patients to shorten the consumption of immunosuppressive drugs, e.g. corticosteroids, that are prescribed to mitigate the inflammation after ALTP-surgery.

Abstract
BACKGROUND Plasma medicine is an innovative research field focused on the application of atmospheric-pressure low-temperature plasmas (ALTP) for therapeutic purposes. Considering the potentials of plasma in ophthalmology, in this study, we evaluated the safety of plasma on the conjunctival tissue in animal models for 6 months. METHODS Twelve adult male New Zealand albino rabbits were divided into four groups. The right eye of each rabbit was chosen for the test and the left eye was considered as the control. Experiments were performed using the Plexr device (GMV, Rocca Priora, RM, Italy). Four plasma spots were applied on the superior part of the conjunctiva (from 10 to 2 o'clock positions) using the continuous mode and a low power level (white handpiece) of the Plexr. For evaluation of the plasma safety, the histopathological changes were assessed 1 week (A), 1 month (B), 3 months (C), and 6 months (D) after the intervention. RESULTS According to the histopathological findings, a mild decrease in blood vessels and severe stromal edema, as well as a superficial epithelium loss, were observed in group A. No chronic inflammation, scar tissue, deposition, and hemorrhage were found in group B. Epithelialization was confirmed by the histological examinations after 1 month. There was no evidence of atypia or dysplasia after 3 and 6 months. CONCLUSION In conclusion, there were no persistent histopathological changes on conjunctival tissue after plasma exposure. Then, plasma can be considered as a minimally invasive alternative method for treating some ocular surface disorders.
