RESUMO
This study aims to evaluate the safety and patient satisfaction of a fast-track procedure for cataract surgery under topical anaesthesia without perioperative anaesthesia care. This is a prospective single-centre study including all cataract procedures in the Centre Ambulatoire de la Chirurgie de la Cataracte at the Hospital of Bourges between May and August 2018. Procedures were performed under topical anaesthesia without the presence of a nurse anaesthesiologist or anaesthesiologist, the patient had not fasted, and no peripheral venous line was placed. Only heart rate and oxygen saturation were monitored intraoperatively with pulse oximetry. Incidence and nature of intraoperative adverse events and surgical complications were recorded. Patient satisfaction was assessed using the Iowa Satisfaction with Anaesthesia Scale (ISAS). In total, 651 cataract surgeries were performed among which 614 (94.3%) were uneventful. Thirty (4.6%) intraoperative adverse events and 8 (1.2%) surgical complications were recorded. All surgeries were successfully completed. No medical emergency team intervention or hospital admittance was encountered. The mean ISAS score was 5.7/6, indicating high patient satisfaction. Cataract surgery in an ambulatory cataract surgery centre without perioperative anaesthesia care is a safe procedure with high patient satisfaction for screened patients. Anaesthesia ressources are scarce and may be more beneficial to more complex ophthalmic or non-ophthalmic surgeries.

PURPOSE: Bacterial keratitis is a sight threatening infection of the cornea which remains one of the most important potential complications of contact lens use. If the corneal ulcer is small, peripheral with no impending perforation present, intensive monotherapy with fluoroquinolones could be used. Therefore, a study was conducted with the objective to provide pharmacological data of the intra-ocular diffusion after administration of Ofloxacin using a scleral lens reservoir, as well as an evaluation of surface tolerability in rabbits. MATERIALS AND METHODS: Samples of corneas, aqueous humor and vitreous were collected to measure the drug levels of Ofloxacin using High Performance Liquid Chromatography. The corneas were examined by electron microscopy scanning and the eyeballs by light polarizing microscopy in order to evaluate surface tolerability. RESULTS: Ofloxacin levels found in the aqueous humor and cornea were higher than those previously reported. The mean Ofloxacin corneal levels exceeded the MIC (Minimum Inhibitory Concentration) for which 90% of isolates are indicated for all bacteria implicated in keratitis. CONCLUSION: To our knowledge, this is the first preclinical study assessing local tolerance and intra-ocular diffusion of Ofloxacin after administration using a scleral lens reservoir.

PURPOSE: To compare a treatment containing carboxymethylcellulose (CMC) and the osmoprotective (OsPr) compatible osmolytes erythritol, L-carnitine, and glycerin (OsPr-CMC) with a standard sodium hyaluronate (Na-HY) formulation in patients with dry eye disease. METHODS: This was a 3-month, phase III, noninferiority study. Patients were randomized 1:1 to receive OsPr-CMC (OPTIVE®) or Na-HY (VISMED®). The primary efficacy outcome was the mean change from baseline in total ocular staining at day 35, scored using the 15-point Oxford scale. Noninferiority was assessed using the adjusted means. The secondary efficacy outcome was change in ocular surface disease index (OSDI) score from baseline to day 35. Other outcomes included tear osmolarity, Schirmer-I test score, OSDI, ease of use, patient acceptability, tolerability, and safety. RESULTS: A total of 82 patients were randomized. The primary efficacy analysis was per protocol (OsPr-CMC, n=37; Na-HY, n=29). OsPr-CMC was noninferior to Na-HY in terms of adjusted mean change (SE) in ocular staining score at day 35: -2.0 (0.33) with OsPr-CMC vs -1.7 (0.37) with Na-HY. Similar improvements were seen in tear osmolarity, Schirmer-I test score, OSDI, and ocular staining for OsPr-CMC and Na-HY. More patients treated with OsPr-CMC vs Na-HY liked using their eyedrops, reported that their eyes felt comfortable, and found the treatment easy to use. Both treatments were well tolerated, with no serious treatment-related adverse events. CONCLUSIONS: Compared with Na-HY, OsPr-CMC was noninferior in terms of efficacy and safety, preferred by patients, and easier to use. Osmoprotection using OsPr-CMC therefore represents a viable option for dry eye disease management.

PURPOSE: To determine whether oral supplementation with omega-3 and omega-6 fatty acids can reduce conjunctival epithelium expression of the inflammatory marker human leucocyte antigen-DR (HLA-DR) in patients with dry eye syndrome (DES). METHODS: This 3-month, double-masked, parallel-group, controlled study was conducted in nine centres, in France and Italy. Eligible adult patients with mild to moderate DES were randomized to receive a placebo containing medium-chain triglycerides or treatment supplement containing omega-3 and omega-6 fatty acids, vitamins and zinc. Treatment regimen was three capsules daily. Impression cytology (IC) was performed at baseline and at month 3 to assess the percentage of cells expressing HLA-DR and to evaluate fluorescence intensity, an alternate measure of HLA-DR. Dry eye symptoms and objective signs were also evaluated. Analyses were performed on the full analysis set (FAS) and per-protocol set (PPS). RESULTS: In total, 138 patients were randomized; 121 patients with available IC were included in the FAS, and of these, 106 patients had no major protocol deviations (PPS). In the PPS, there was a significant reduction in the percentage of HLA-DR-positive cells in the fatty acids group (p = 0.021). Expression of HLA-DR as measured by fluorescence intensity quantification was also significantly reduced in the fatty acids group [FAS (p = 0.041); PPS (p = 0.017)]. No significant difference was found for the signs and symptoms, but there was a tendency for improvement in patients receiving the fatty acids treatment. CONCLUSION: This study demonstrates that supplementation with omega-3 and omega-6 fatty acids can reduce expression of HLA-DR conjunctival inflammatory marker and may help improve DES symptoms.
