Abstract
INTRODUCTION The lipid layer of the tear film is critical to maintaining the integrity of the tear film and absence in the tear film lipid layer (TFLL) is one of the main causes of evaporative dry eye (EDE) in dry eye disease patients, resulting in excessive evaporation (so-called hyperevaporative dry eye). This study protocol will be designed to assess and compare the effects of intense pulsed light (IPL), heated eye mask (HEM), vectored thermal pulsation system (VTPS) and eyelid massage device (EMD) for improving signs and symptoms of EDE. METHODS AND ANALYSIS Patients with EDE will be randomly divided into IPL, HEM, VTPS and EMD groups and will be followed up for 6 weeks. The primary outcome measure will be non-invasive tear breakup time (NITBUT). The secondary outcome measures will include, TFLL score, meibomian gland quality and expressibility change from baseline conjunctivocorneal staining with fluorescein and lissamine, tear meniscus height, conjunctival hyperaemia (redness score) and ocular surface disease index questionnaire. Additionally, adverse events will be monitored and documented. ETHICS AND DISSEMINATION Ethics approval number: IRB(2023)K019.01. The findings will be shared regardless of the effect's direction. TRIAL REGISTRATION NUMBER NCT05923528.

Abstract
INTRODUCTION The primary objective of this study is to assess whether the combination of intense pulsed light (IPL) with 3% diquafosol (DQS) ophthalmic solution is more effective than intense pulsed light in alleviating signs and symptoms of dry eye disease (DED). METHODS This randomized study included 66 participants with evaporative dry eye (EDE) who received IPL + DQS therapy (n = 44 eyes), IPL therapy (n = 44 eyes), or sham therapy (n = 44 eyes). All participants were examined at baseline (D0), day 14 (D14), and day 28 (D28) for non-invasive break-up time (NITBUT), tear-film lipid layer (TFLL), corneal conjunctival staining (CS), meibomian gland quality (MGQ), meibomian gland expression (MGEx), and ocular surface disease index (OSDI). RESULTS At day 28, comparison among the IPL + DQS therapy, IPL therapy, and sham therapy found significant differences in the mean NITBUT (12.03 ± 1.27 versus 10.47 ± 3.48 versus 4.57 ± 0.46; p < 0.001), TFLL (2.09 ± 0.29 versus 2.27 ± 0.45 versus 2.89 ± 0.65; p < 0.001), CS (1.43 ± 0.82 versus 1.93 ± 1.32 versus 3.52 ± 1.00; p < 0.001), MGQ (1.55 ± 0.66 versus 1.91 ± 0.77 versus 2.66 ± 0.53; p < 0.001), MGEx (1.27 ± 0.45 versus 1.75 ± 0.44 versus 2.41 ± 0.50; p < 0.001), and OSDI score (19.36 ± 7.01 versus 24.77 ± 4.68 versus 42.61 ± 7.49; p < 0.001); significant improvements in NITBUT, TFLL, CS, MGQ, MGEx, and OSDI were found in the IPL + DQS therapy and IPL therapy, while the sham therapy had no significant improvements. CONCLUSION Combining 3% diquafosol ophthalmic solution with intense pulsed light was superior to IPL therapy alone in relieving the signs and symptoms of patients with severe evaporative DED.

Abstract
Background: Contact lens-related dry eye (CLDE) is common in contact lens (CL) wearers and can lead to ocular pain, decreased visual quality, and reduced quality of life. Objective: The purpose of this prospective, randomized, examiner masked study was to compare the effectiveness of intense pulsed light (IPL) and heated eye mask (HEM) for relieving CLDE. Methods: The final analysis included 60 patients (30 in the IPL group and 30 in the HEM group) who were using CL and had been suffering contact lens discomfort for more than a year. The IPL treatment group had two IPL treatments spaced 3 weeks apart, whereas the HEM group received HEM daily for 6 weeks (42 days). Non-invasive tear break-up time (NITBUT), tear-film lipid layer (TFLL), conjunctival fluorescein staining, meibum gland quality and expression, conjunctival redness score, ocular surface disease index (OSDI), best-corrected visual acuity, endothelial cell count, and intraocular pressure were assessed at baseline: first visit (V1), second visit (V2), and third visit (V3). Results: The mean age of the IPL group was 28.6 ± 4.3 years (16 females, 53%) and that of the HEM group was 28.6 ± 4.2 years (16 females, 53%). Mean NITBUT for the IPL group at V2 was 5.53 ± 0.77 sec (p < 0.001) and at V3 was 7.72 ± 0.88 sec (p < 0.001); the IPL group demonstrated a clinically and statistically significant improvement in mean NITBUT. In addition, the HEM group showed a clinically and statistically significant improvement in mean NITBUT at V3 (5.86 ± 0.76 sec, p < 0.001). At V3, the C-OSDI, TFLL score, and meibum gland quality and expressibility all increased considerably (p < 0.05) in both groups. Conclusions: Our results imply that IPL or HEM treatment of CLDE can be safely used to relieve symptoms of CLDE. In addition, IPL treatment is more effective in improving the general stability of the tear-film and decreasing the need for artificial tears in CLDE.

Management of Post-LASIK Dry Eye with Intense Pulsed Light in Combination with 0.1% Sodium Hyaluronate and Heated Eye Mask. Ophthalmol Ther 2022; 11:161-176. [PMID: 34741758 PMCID: PMC8770788 DOI: 10.1007/s40123-021-00418-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Accepted: 10/25/2021] [Indexed: 11/09/2022] Open
Abstract
INTRODUCTION Laser in situ keratomelieusis (LASIK) is one of the most frequently performed refractive treatments. Dry eye (DE) is common in patients after LASIK and can be bothersome postoperatively. Therapies such as intense pulsed light (IPL), sodium hyaluronate (SH) and heated eye mask (HEM) have been reported to improve signs and symptoms of DE . AIM The purpose of this prospective study was to evaluate and compare the effects of IPL and 0.1% SH (IPL group, 50 eyes) and IPL in combination with 0.1% SH and HEM (IPL + group, 50 eyes) in participants with persistent post-LASIK DE. METHODS The final analysis included 100 patients (100 eyes) who had LASIK for myopic correction and had been experiencing moderate to severe DE following LASIK for over a year. Participants were randomly assigned to either the IPL group (2 IPL sessions) or IPL + group (2 IPL sessions and daily HEM for 4 weeks), and both groups continued the use of daily 0.1% SH (HYLO-COMOD®) preservative-free eye drops. Non-invasive tear break-up time (NITBUT), tear film lipid layer (TFLL), lower tear meniscus height (LTMH), meibomian gland quality (MGQ), meibomian gland expressibility (MGEx), corneal fluorescein staining (CFS), ocular surface disease index (OSDI) and artificial tear usage (ATU) survey were assessed at baseline (BL) and follow-up at 2 (F1) and 4 weeks (F2). RESULTS Following the treatment protocol, all dry eye (DE) parameters assessed in this study improved significantly (P < 0.05) in both groups at F2 compared with their respective BL measurements. Inter-group comparison at F2 found significant differences in their NITBUT (IPL: 6.06 ± 0.59 vs. IPL +: 6.67 ± 0.86, P < 0.001), TFLL (IPL: 1.90 ± 0.65 vs. IPL +: 1.60 ± 0.64, P = 0.021), LTMH (IPL: 0.186 ± 0.053 vs. 0.204 ± 0.034, P = 0.003), MGQ (IPL: 1.48 ± 0.54 vs. IPL +: 1.26 ± 0.56, P = 0.026), MGEx (IPL: 1.62 ± 0.53 vs. IPL +: 1.44 ± 0.50, P = 0.038) and OSDI (IPL: 32.54 ± 6.85 vs. IPL +: 29.76 ± 4.74, P = 0.001), while CFS score (IPL: 4.02 ± 0.65 vs. IPL +: 3.96 ± 0.73, P = 0.652) and ATU (IPL: 1.88 ± 0.63 vs. IPL +: 1.72 ± 0.50, P = 0.159) showed no significant difference. CONCLUSION Post-LASIK DE signs and symptoms can be improved by combining therapies such as IPL, HEM and 0.1% SH. Increased TFLL due to a combination of IPL, 0.1% SH and HEM had a greater positive impact on the subjective and objective DE measurements in participants with persistent post-LASIK DE.

Abstract
PURPOSE To compare the efficacy of intense pulsed light (IPL) and near-infrared light (NIL) treatments in alleviating symptoms and signs of dry eye disease (DED). METHODS Patients diagnosed with DED at the Peking University Third Hospital Eye Center from January 2019 to October 2019 were randomized to undergo either NIL therapy combined with meibomian gland expression (MGX; NIL Group) or IPL combined with MGX (IPL Group). Treatments were performed three times at 1-month intervals. DED signs and symptoms were evaluated before every treatment. We compared the clinical improvement within and between the groups. Additional comparisons were made according to the meibomian gland (MG) dropout grade. RESULTS A total of 260 eyes of 130 patients (mean age, 49.68 ± 18.01 years) were included. The dryness and total symptom scores and the MG expressibility and secretion quality (upper and lower eyelids) significantly improved after the three treatments in both groups (p < 0.05). However, IPL had superior efficacy in improving blurred vision, photophobia, burning, increased secretions and the total symptom score at 2 months in patients with more severe MG dropout. CONCLUSIONS Both IPL and NIL treatments were effective in the treatment of DED, but IPL provided greater symptom improvement, particularly in patients with severe MG dropout. NIL can be a new therapeutic option for the treatment of DED.

Abstract
BACKGROUND Inadequate meibomian glands (MGs) secretion can lead to dry eye signs and symptoms. Tear film lipid layer (TFLL) secreted by MGs protects and prevents rapid evaporation of tear film. The purpose was to assess TFLL alteration and function in patients with evaporative dry eye (EDE) using tear interferometry after optimal pulse light technology (OPT) intense pulsed light (IPL). METHODS This prospective randomized examiner-masked sham- controlled study included 86 participants (142 eyes) with DED. IPL or sham procedure was performed on day 0, 21, and 42. Ocular Surface Disease Index (OSDI), non-invasive breakup time (NITBUT), interferometric fringe pattern determined TFLL quality, fluorescein staining (FS), and meibum gland (MG) were assessed at day 0, 21, 42 and 3-month. RESULTS At 3-month, TFLL, NITBUT, MG drop-out, MG quality, MG expressibility, FS and OSDI improved significantly (P < 0.05) in the IPL group, while the sham group had no significant improvements. Except for Meibo-score and FS, all parameters significantly correlated with the improvement in TFLL following IPL treatment. Additionally, artificial tears usage was significantly less in the IPL group from D-42 onwards. CONCLUSION IPL treatment demonstrated the ability to improve TFLL quality and clinically reduced sign and symptoms of DED thereby reducing the frequency of artificial tears use.

Abstract
AIM The prevalence of contact lens related dry eye (CLDE) is high and can lead to ocular discomfort, reduced quality of vision and life. The aim of this study was to assess the efficacy of intense pulsed light (IPL) treatment in alleviating signs and symptoms of CLDE. DESIGN Prospective, randomised, examiner masked study. METHODS This prospective study was conducted on 152 eyes of 76 patients (IPL group, n = 76 eyes; control group, n = 76 eyes) wearing contact lens (CL) and experiencing CLDE for more than 1 year. The IPL treatment group underwent two IPL treatment sessions at 3-week intervals while the control group received sham IPL treatment. Best-corrected visual acuity (BCVA), ocular surface disease index (OSDI), non-invasive breakup time (NITBUT), tear film lipid layer (TFLL) quality, fluorescein staining (FS), meibum gland (MG) quality and expression, endothelial cell count (ECC) and intraocular pressure (IOP) were assessed at baseline (D-0), day-21 (D-21) and day-42 (D-42) after IPL treatment. RESULTS The mean age of treatment group and control group was 28.47 ± 5.16 years (21 females, 28 %) and 28.58 ± 4.33 years (23 females, 30 %) respectively. IPL treatment group had clinically and statistically significant improvement in mean NITBUT was observed at D14 (5.24 s, P<0.001) and D28 (6.08 s, P<0.001). OSDI, TFLL score and MG quality and expressibility all improved significantly (P<0.001) at D-42, whereas BCVA, ECC and IOP showed no significant changes at D-21 and D-42 in IPL treatment group. The control group showed no significant improvement in all parameters at D-21 and D-42. CONCLUSION Our findings suggest that CL related DE can be safely alleviated with IPL treatment as it reduced the severity of symptoms, improved the overall tear film stability and reduced artificial tear use in participants with CLDE.

Siperstein R, Wikramanayake TC. Intense Pulsed Light as a Treatment for Senile Purpura: A Pilot Study. Lasers Surg Med 2020; 53:926-934. [PMID: 33615512 DOI: 10.1002/lsm.23358] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 11/01/2020] [Accepted: 11/08/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND AND OBJECTIVES Senile purpura is a common condition characterized by recurrent ecchymoses in the elderly on the extensor surfaces of the forearms, hands, and legs. Our objective is to assess the efficacy and safety of a protocol using intense pulsed light (BBL; Sciton Inc., Palo Alto, CA) to improve the appearance of senile purpura on subjects' extensor forearms. STUDY DESIGN/MATERIALS AND METHODS Five subjects over 65 years of age, with ecchymotic lesions measuring over 1 cm on each forearm and five younger subjects under 35 years of age, without any ecchymotic lesions, were included in the study. The subjects were treated on one randomized forearm with a new intense pulsed light protocol for four weekly sessions. Photographs and subject questionnaires were taken weekly before each treatment as well as 1 month after all treatments. Skin biopsies were taken 1 day after the last of four weekly treatments. Histological analysis, including hematoxylin and eosin, elastic van Gieson, and Masson's Trichrome staining, were carried out to assess both the epidermal thickness and dermal connective tissue structure. The protocol consists of multiple passes using an intense pulsed light (BBL; Sciton Inc.) device in which the wavelength, filter, and fluence are adjusted for each step. Step 1 uses infrared light (800-1,400 nm), high intensity, a smooth adapter, and a constant motion technique. Step 2 employs a 590-nm filter with two different fluences and step 3 utilizes a 560-nm filter. The fluence of steps 2-3 is increased by 1 J each treatment if no side effects are noted. RESULTS Using a new intense pulsed light protocol in subjects with senile purpura, both the number and square area of ecchymoses on the treated arm were significantly reduced (P = 0.02 and P = 0.04, respectively, paired t test) as compared with the untreated arm at 1 month after four weekly treatments. Despite this pilot study including challenging cases of subjects on both inhaled and injected corticosteroids and blood thinners, all subjects with senile purpura had at least a 50% reduction in the total square area of their ecchymoses on their treated arm. There were no significant or long-lasting side effects, and all subjects reported satisfaction with the treatment with a desire to continue treatments on their control arm. Blinded evaluators were able to select 100% of the time in the subjects with senile purpura, which was the treated arm as compared with the control arm when reviewing photographs from 1 month after the last treatment. In addition, several subjects were noted to have a significant improvement in the appearance of hemosiderin deposition and photodamage. Histologically, intense pulsed light treatments significantly increased epidermal thickness in elderly subjects by 21.14% (P = 0.0153, two-tailed, paired t test), to levels comparable with young subjects. Such restoration is consistent with the other histological observations by blinded evaluators of more abundant and organized collagen fibers in the dermis and reduced aggregates of disorganized elastin fibers. CONCLUSION This new intense pulsed light protocol is safe and effective in improving the clinical appearance of senile purpura as well as preventing future lesions by improving the structure of the skin by increasing epidermal thickness and improving collagen and elastic fiber morphology. The treatment was well-tolerated, adverse effects were minimal, and there was high patient satisfaction. Lasers Surg. Med. 2020. © 2020 Wiley Periodicals LLC.

Lasers Surg Med 2020; 53:549-556. [PMID: 32757279 DOI: 10.1002/lsm.23303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Revised: 06/23/2020] [Accepted: 07/19/2020] [Indexed: 11/12/2022]
Abstract
BACKGROUND AND OBJECTIVES We previously demonstrated that intense pulsed light (IPL) irradiation prior to wounding improved the wound healing in rats with diabetes mellitus (DM). Also, we found that IPL upregulated the expression of aquaporin 3 (AQP3), a protein that is crucial for wound healing, in normal rats. This present study aimed to examine the involvement of AQPs in the IPL-enhanced wound healing in diabetic rats. STUDY DESIGN/MATERIALS AND METHODS Streptozotocin was used to induce diabetes in Sprague-Dawley rats. Animals were divided into four groups: normal group, DM only group, DM rats with IPL treatment 2 weeks before wounding (DM + IPL-Pre group), and DM rats with concurrent IPL irradiation and wounding (DM + IPL-Con group). Wounds were created on the dorsal skin of rats. The expressions of AQP1, 3, 4, 7, and 9 in the pre-injured skin, periwound, and wound were determined. RESULTS Among all the AQPs analyzed, only the expressions of AQP3 and AQP7 were significantly altered. Unirradiated diabetic rats showed much higher expression level of AQP3 in the regenerating skin compared with normal rats. IPL pretreatment, but not concurrent treatment, attenuated the expression toward the level detected in the normal wounds. In contrast, a lower expression level of AQP7 was noted in the regenerating skin of DM only rats and IPL pretreatment upregulated the expression to a level similar to that in the normal rats. CONCLUSION The beneficial effect of IPL pretreatment on the wound healing in diabetic rats might involve a mechanism by which the expression of AQPs is regulated. Lasers Surg.

Abstract
Wound healing is a complex physiological process that occurs in the human body involving the sequential activation of multiple cell types and signaling pathways in a coordinated manner. Chronic wounds and burns clearly decrease quality of life of the patients since they are associated with an increase in physical pain and socio-economical complications. Furthermore, incidence and prevalence of chronic wounds (unlike burns) have been increasing mainly due to population aging resulting in increased costs for national health systems. Thus, the development of new and more cost-effective technologies/therapies is not only of huge interest but also necessary to improve the long-term sustainability of national health systems. This review covers the current knowledge on recent technologies/therapies for skin regeneration, such as: wound dressings; skin substitutes; exogenous growth factor based therapy and systemic therapy; external tissue expanders; negative pressure; oxygen; shock wave, and photobiomodulation wound therapies. Associated benefits and risks as well as the clinical use and availability are all addressed for each therapy. Moreover, future trends in wound care including novel formulations using metallic nanoparticles and topical insulin are herein presented. These novel formulations have shown to be promising therapeutic options in the near future that may change the wound care paradigm.
