Background. Dry eye disease (DED) is one of the most common complications following refractive surgery.Purpose. Evaluate the efficacy of an osmoprotective eye drop (Optive®) for the management of induced DED in refractive surgery patients.Design. Double-masked randomised controlled trial.Methods. Twenty-two refractive surgery patients oriented to apply FreshTears (FT;n=13) or Optive (Op;n=9), topically, QID, for 3 months. Eye exams were performed before surgery (T0) and 1-month (T1) and 3-month (T3) follow-up and consisted of tear film osmolarity, Schirmer 1 test, tear film breakup time (TBUT), fluorescein staining, and ocular surface disease index (OSDI) and patient symptoms questionnaires.Main Outcome Measures. Pain and osmolarity.Results. Pain increased significantly for FT at T3 (p<0.05). A reduction in osmolarity was observed at T1 and T3 for Op group (p<0.01) and at T3 for FT group (p<0.05). TBUT showed a decrease between T0 and T1 for FT (p<0.05). Schirmer 1 values increased significantly for Op in T1.Conclusions. Op was superior to FT in regard to pain, osmolarity, TBUT, and Schirmer 1. Osmoprotectant solutes, such as L-carnitine, could attenuate inflammation and secondary DED. Osmoprotective lubricants can be effectively applied for the prevention of refractive surgery-related dry eye symptoms and signs.

Abstract Purpose Dry eye symptoms after conventional cataract surgery are a very common problem. Until now, only few data are available on objective tear film parameters in regard to femtosecond laser-assisted cataract surgery (LCS). Aim of this study was therefore to analyze and compare tear film parameter changes between LCS and conventional cataract surgery. Methods A consecutive group of 34 patients, scheduled for cataract surgery, were randomly selected for either LCS or conventional cataract surgery (17 patients/group). Tear film assessments including tear film osmolarity, Schirmer test, MMP-9 analysis via quantitative ELISA, corneal sensitivity, corneal fluorescein staining, and conjunctival fluorescein staining were sequentially evaluated pre- as well as 1 and 3 months postoperatively. Results Both groups showed no significant difference in baseline characteristics. All surgeries were performed without any complications. After 1 and 3 months, there was no statistically significant difference in regard to tear film osmolarity (1 month: p = 0.81, 3 months: p = 1.0), Schirmer test (1 month: p = 0.35, 3 month: p = 0.08), and MMP-9 concentration (1 month: p = 0.36, 3 month: p = 0.28) between the two groups. Conclusions Neither LCS nor conventional cataract surgery affected objective tear film parameters significantly during our 3-month postoperative observation period. Hence, both surgical techniques can be equally used to treat patients without prior dry eye symptoms.

BackgroundTo evaluate the efficacy of botulinum toxin A (BoNT-A) in reducing photophobia and dry eye symptoms in individuals with chronic migraine. Additionally, we aimed to evaluate tear film volume as a potential contributor to symptoms in these patients.MethodsRetrospective review of 76 patients who received BoNT-A for chronic migraine between 23 August 2017 and 13 December 2017 at the Miami Veterans Affairs Medical Center Neurotoxin Clinic. Demographic data and all comorbidities were queried via chart review. Standardised validated surveys were administered to assess symptoms prior to and after BoNT-A injection. Preinjection tear volumes were obtained using the phenol red thread (PRT) test.ResultsPreinjection migraine, photophobia and dry eye symptom scores were all significantly correlated, p<0.05, and none were associated with preinjection PRT results. After BoNT-A, improvements in migraine, photophobia and dry eye symptoms were also significantly correlated, p<0.05 and similarly did not associate with preinjection PRT results. Photophobia scores significantly improved following BoNT-A, while dry eye symptoms significantly improved in those with severe symptoms at baseline (DEQ-5 score ≥12), p=0.027. In logistic regression analysis of all individuals with dry eye symptoms (DEQ-5 ≥6), individuals with more severe dry eye symptoms were more likely improve, OR 1.27, 95% CI 1.06 to 1.51, p<0.01.ConclusionsBoNT-A significantly improved photophobia in patients being treated for migraine and also improved dry eye symptoms in patients with severe symptoms at baseline, independent of baseline tear film volume. These improvements may be due to modulation of shared trigeminal neural pathways.

: We aimed to examine the effectiveness of eye-light therapy in improving the dry eye symptoms.: The retrospective case series where patients who underwent eye-light therapy between March 2019 to May 2020 were analyzed. Twenty patients aged ≥18 years with dry eyes were included. Patients with ocular infections, complications, contact lens users and missing data were excluded. OSDI scores and tear parameters such as  noninvasive break up time (NIBUT), lipid layer thickness (LLT), tear meniscus height, meibography of upper and lower lid were evaluated pre and post one month Eye-Light therapy.: Twenty patients with mean±SD age of 43.55±20.53 years and mean spherical equivalent refractive error of 0.69±1.79 diopters were analyzed. OSDI was significantly associated with NBUT (r=-0.50, P = 0.02), lipid layer thickness (r=-0.45, P=0.047) and tear height (r =-0.45, P=0.046).  OSDI was positively associated with upper lid meibography (r=0.74, P=&#60;0.001) and lower lid meibography (r=0.45, P=0.045). Post-therapy, reduction in OSDI score post-therapy was present, NBUT was similar, lipid layer thickness and tear height were increased, meibography of upper lid was reduced, and meibography of lower lid did not alter much. Eye-light therapy is effective in reducing dry eye related symptoms with minimal immediate effect on tear film parameters post therapy. Eye-light therapy acts as an adjunct to ameliorate MGD. MGD being a chronic disease requires sustained therapy with environmental changes. Long term evaluation is required to assess the tear film changes and the pattern of efficacy of light therapy.

Purpose. To assess inflammatory involvement of cornea in dry eye by means of confocal microscopy, evaluating the presence and distribution of Langherans cells (LCs). Methods: 98 eyes of 49 subjects were enrolled: 18 subjects affected by Sjögren Syndrome Dry Eye (SSDE), 17 with Non-Sjögren Syndrome Dry Eye (NSSDE), 14 healthy volunteeers. Dry eye symptoms, tear film, ocular surface damage and corneal confocal microscopy were analized. Results: A significant increase of LCs density was observed at sub-basal nerve plexus (SSDE = 79 cells/mm2 and NDE = 22 cells/mm2; p = 0,0031) and sub-epithelial nerve plexus (SSDE = 38 cells/mm2 and NDE = 3 cells/mm2; p = 0,0169) in central cornea of SSDE group. An increased number of LCs from the center to the periphery of the cornea was observed, significant only in healthy volunteers group. In dry eye patients there was an increase in LCs density in both peripheral and central cornea with a significant difference between NDE (14,66 cells/mm2) and SSDE (56,66 cells/mm2) only in central cornea (p = 0,0028). In SSDE group, mean density of LCs in central cornea results also superior to NSSDE group (29,33 cells/mm2). There was no correlation between LCs density and dry eye symptoms, tear film deficiency and ocular surface damage. Conclusion: This study demonstrates the activation of an inflammatory and immunological reaction in cornea of NSSDE and SSDE patients. Confocal microscopy can be an important diagnostic tool in evaluation and follow-up of dry eye disease.

Purpose. To investigate the association between preoperative dry eye symptoms on postoperative pain and discomfort after photorefractive keratectomy (PRK). Methods. A retrospective case series of 151 consecutive patients, who underwent myopic PRK in both eyes between 5/2016 and 5/2017. Patients with positive dry eye disease (DED) signs on clinical examination or with known DED were excluded. Patients underwent a subjective evaluation for dry eye symptoms using ocular surface disease index (OSDI) and modified standard patient evaluation of eye dryness (SPEED) questionnaires. One day postoperatively, the patients were evaluated again by a questionnaire of pain, discomfort, photophobia, foreign body sensation, satisfaction with vision, and frequency of usage of anesthetic drops. Results. Fifty-two patients had any preoperative dry eye symptoms (OSDI score > 0) compared to 99 nonsymptomatic patients (OSDI score of 0). Postoperatively, the symptomatic dry eye patients suffered significantly more pain than the nondry eye patients (p=0.02). Thirteen patients had a cumulated modified SPEED score >4 (moderate to severe) in comparison to 138 patients with score of 0–4 (non to mild). Patients with moderate to severe preoperative symptoms suffered more pain (p=0.006), photophobia (p=0.005), and epiphora (p=0.03). No statistically significant difference was seen in postoperative subjective visual quality (p=0.82) between the two groups. Conclusion. Preoperative dry eye symptoms may be associated with postoperative pain, epiphora, and photophobia and thus influence negatively on patient satisfaction with this procedure.
