[PMID: 38435373 PMCID: PMC10906276 DOI: 10.2147/opth.s446804] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 02/15/2024] [Indexed: 03/05/2024] Open
Abstract
Purpose To compare the effect of treatment with preservative-free dexamethasone, NSAIDs and trehalose/hyaluronic acid eye drops with the preservative benzalkonium chloride containing dexamethasone and NSAIDs after cataract surgery in dry versus non-dry eyes. Patients and Methods In this prospective randomized intervention study, dry eye tests were performed before and 6 weeks after cataract surgery. Patients were considered as having dry eye, SDE (sign of dry eye), if at least one of the following dry eye tests were abnormal; corneal fluorescein staining (CFS), non-invasive keratograph breakup time (NIKBUT) or tear osmolarity. Patients with SDE were randomly assigned to one of two groups. Group 1 patients were treated with dexamethasone and bromfenac eye drops with the preservative benzalkonium chloride (BAC). Group 2 patients were treated with preservative-free dexamethasone and preservative-free diclofenac, as well as a preservative-free lubricant with trehalose and hyaluronic acid both before and after surgery. Patients with normal tear film status acted as the control group (group 3) and received same treatment as group 1. Results A total of 215 patients were enrolled six weeks after surgery, the number of patients with SDE decreased significantly in groups 1 and 2 (p <0.001). Subjective symptoms and objective measures including osmolarity, NIKBUT, CFS, and tear film thickness (TFT) improved after surgery, tear production remained unchanged, while corneal sensitivity and meibomian gland dysfunction (MGD) parameters worsened. In the control group with normal tear-film status, SDE increased significantly after the surgery (p <0.001). There were no statistically significant differences in tear film parameters between the three groups after surgery. Conclusion After cataract surgery, patients with mild to moderate dry eyes may experience improved tear film status and reduced symptoms. However, we found no additional beneficial effect on dry eye parameters with treatment with preservative-free dexamethasone, NSAIDs, and lubricants compared to preservative-containing eye drops.

Abstract
INTRODUCTION This study aimed to compare the effect of two preservative-free (PF) artificial tears, one containing carboxymethylcellulose (CMC) (control group) vs another containing hyaluronic acid and hydroxypropyl guar (HA + HP-guar) (study group), on the healing of the corneal epithelium and the ocular discomfort after bilateral photorefractive keratectomy (PRK) surgery. METHODS A total of 68 patients that were scheduled to have PRK to correct myopia were randomized into two groups: 34 patients (68 eyes) in the study group and 34 patients (68 eyes) in the control group. Ocular examinations were performed on postoperative days 1, 4, 7, 30, and 90, evaluating the diameter of the de-epithelized cornea, the fluorescein staining using the Oxford scale, the tear film osmolarity and stability (tear breakup time), and the pain using visual analog scale (VAS). RESULTS On postoperative day 4, 97% of the study eyes vs 84.4% of the control eyes were completely re-epithelized (p = 0.01). Less ocular pain was observed on postoperative day 3 in the study group (5.0 (3.0-6.0) vs 6.0 (3.5-7.0), p = 0.03). No differences were observed beyond postoperative day 7 in the healing of the corneal epithelium, non-invasive Keratograph breakup time (NIKBUT), and the self-perceived ocular discomfort between the two groups. CONCLUSION The current study shows faster healing of the corneal epithelium and less ocular pain and discomfort in the first days after PRK with the use of topical lubricants containing HA + HP-guar compared to conventional CMC artificial tears, probably due to the different trophic effect of the aforementioned tears on the corneal epithelial cells.

PURPOSE To compare the effect of trehalose 3%/hyaluronic acid 0.15% vs hyaluronic acid 0.15% eyedrops in reducing ocular surface inflammation after cataract surgery. SETTING Perugia, Italy. DESIGN Randomized, prospective study. METHODS Patients with healthy ocular surface were enrolled. Tear break-up time (TBUT), Schirmer test, corneal fluorescein staining (CFS), ocular surface disease index (OSDI) and in vivo confocal microscopy (IVCM) were performed preoperatively and at 1 months, 4 months, and 8 months postoperatively. Patients were randomly assigned to receive trehalose 3%/hyaluronic acid 0.15% eyedrops (Group A), hyaluronic acid 0.15% eyedrops (Group B), or no treatment (Group C). RESULTS 98 patients were randomized as follows: 33 in Group A, 33 in Group B, and 32 in Group C. Schirmer test increased at 1-month follow-up in Group A and unchanged in Groups B and C. TBUT and CFS increased at 1-month follow-up in Group A and after 8 months in Groups B and C. OSDI score decreased at 1-month follow-up in Group A and at in Groups B and C. IVCM showed a reduction in the number of nerve fibers of the subbasal nerve plexus at 1 month in all groups and progressively increased to preoperative levels at 4 months in Group A, and at 8 months in Groups B and C. Tortuosity and reflectivity of subbasal plexus progressively decreased to became significant at 4-month follow-up in Group A whereas increased at 1-month follow-up and become normal at 8-month follow-up in Groups B and C. Langerhans cells and activated stromal keratocytes were higher in Groups B and C throughout the follow-up with a significantly lower density of hyperreflective stromal cells in Group A. CONCLUSIONS Trehalose 3%/hyaluronic acid 0.15% eyedrops were effective in reducing inflammation and dry-eye symptoms.

Abstract
Purpose: The efficacy of using preservative-free 0.15% sodium hyaluronate eyedrops for dry eye disease after femtosecond laser- assisted cataract surgery (FLACS) was evaluated. Methods: This prospective randomized study was conducted on patients with dry eye who were scheduled for FLACS among those with Tear Film & Ocular Surface Society Dry Eye Workshop II Dry Eye Levels 1 and 2. In total, 37 eyes scheduled for FLACS were randomized to the treatment group (n = 19) or control group (n = 18). Corneal and conjunctival fluorescein staining (CFS), tear breakup time (TBUT), Schirmer I test (SIT) value, ocular surface disease index (OSDI), meibomian gland evaluation result, and lipid layer thickness were evaluated for all patients, preoperatively and at 1 and 3 months postoperatively. Results: In the treatment group, the OSDI and CFS scores were significantly lower at 3 months postoperatively than at baseline, but the TBUT and SIT values were significantly increased. In the control group, TBUT was significantly shorter at 3 months postoperatively than at baseline, SIT values were significantly decreased at 1 and 3 months postoperatively compared with the baseline, and meibum quality was significantly aggravated at 1 month postoperatively compared with the baseline. In the treatment group, OSDI improved significantly from baseline at 1 and 3 months. TBUT increased significantly in the treatment group at postoperative 3 months. Meibomian gland quality showed clinically better results in the treatment group than in the control group at postoperative 3 months. There were no significant differences in corneal and CFS, lipid layer thickness, and other dry eye disease parameters between the treatment and control groups. Conclusions: Preservative-free 0.15% sodium hyaluronate eyedrops were effective for improving dry eye symptoms and tear film stability after FLACS.

Abstract
Hydroxypropyl-guar (HPG) is a thickening agent first added to lubricating eye drops in 2003. This agent, which enhances viscosity, has been used in the SYSTANE® family of lubricant eye drops (Alcon Laboratories, Inc., Fort Worth, TX, USA). HPG forms a partially linked gel with borate to prolong the retention of demulcents, such as polyethylene glycol and propylene glycol, on the eye. This helps to protect the ocular surface, thereby reducing the symptoms of dry eye disease (DED). The definition of DED has evolved with advances in research, leading to changes in HPG-containing eye care solutions. This article reviews current knowledge on the use of HPG-containing lubricating eye drops in the management of DED.

Abstract
Dry eye disease (DED) is a multifactorial ocular condition characterized by a loss of homeostasis of the tear film resulting in ocular symptoms of discomfort, irritation, and visual disturbance, all of which significantly impact the patients’ social and occupational quality of life. While management of DED depends on the severity of symptoms and signs, use of artificial tear products (ATPs) that replace or supplement the deficient natural tear film is the mainstay treatment option. In this review, we present a decade of evidence on Systane Ultra® (polyethylene glycol [PEG]/propylene glycol [PG] with hydroxypropyl guar [HP guar]) in effectively managing DED. The active demulcents in Systane Ultra®—PEG, PG, along with HP guar gelling technology—provide optimal ocular surface protection and lubrication to heal damaged areas of the cornea caused by DED and, therefore, are recommended for patients with both aqueous and/or mucin layer deficiencies. Over the years, several clinical studies have shown that PEG/PG with HP guar provides long-lasting relief from dry eye and has often been chosen as a standard or comparator against other ATPs. Here, we describe the salient features of PEG/PG with HP guar—its constituents and their mechanisms of action. Furthermore, we summarize results from a systematic literature search that identified 23 relevant publications further emphasizing on the effectiveness and safety of PEG/PG with HP guar in alleviating the signs and symptoms of DED.

Abstract
Purpose To evaluate the effects of a hydroxypropyl guar (HPG) and hyaluronic acid (HA) ophthalmic solution in terms of post-cataract surgery dry-eye disease (DED) prevention. Patients and Methods In this retrospective study, the data of 419 patients not previously affected by DED, who had undergone unilateral cataract surgery in 17 Italian centers with different perioperative lubricating regimens, were retrospectively reviewed. Patients who had instilled HPG/HA solution 3 times/day in the preoperative week and for two postoperative months were included in group A; group B only instilled HPG/HA for two postoperative months; group C did not instill any perioperative artificial tears. All patients followed the same antibiotic and anti-inflammatory postoperative topical regimen. The scores of SPEED (Standard Patient Evaluation of Eye Dryness) questionnaire, tear break-up time (BUT) and corneal fluorescein staining (CFS, Oxford scale), performed at the preoperative visit and at one, four and eight postoperative weeks, were evaluated. Results In groups A and B, the SPEED scores were significantly lower than group C in the whole postoperative period. In group A, the SPEED scores were significantly lower than group B 1 and 4 weeks after surgery (p<0.001 and p=0.021). In group C, 25% of patients reported symptom scores corresponding to mild-moderate dry eye 4 and 8 weeks after surgery. The fluorescein tear BUT in groups A and B was significantly higher than group C in the whole postoperative period (p<0.001). In group A, BUT was significantly higher than group B 4 weeks after surgery (p=0.016). More patients showed no corneal fluorescein staining (CFS grade=0) in groups A and B than group C at all the postoperative visits. Conclusion The hydroxypropyl guar and hyaluronic acid ophthalmic solution was effective at reducing post-cataract surgery ocular discomfort and tear instability, particularly if also administered in the preoperative period.

Abstract
INTRODUCTION To evaluate the effects of a new lubricating, antioxidant solution (VisuEvo®) on dry eye disease (DED) in patients undergoing cataract surgery. METHODS Patients requiring cataract surgery with either healthy ocular surface or mild DED (tear break-up time, TBUT > 7, Schirmer I test > 15 mm/5 min) were enrolled in this multicenter, open-label, randomized, prospective study. Scheduled visits were 2 weeks before surgery (screening), day of surgery (V0), week 1 (V1), and 2 (V2) after surgery. VisuEvo® was self-administered three times daily for the whole study duration (group A); the control group (group B) had no tear substitute administration. The primary endpoint was the change in TBUT over time; the secondary endpoints were changes in Ocular Surface Disease Index (OSDI), ocular surface staining, the Schirmer I test, and osmometry. RESULTS A total of 45 patients were included (group A, 23; group B, 22; age 74 ± 8 years). At the screening, TBUT was similar between the groups (group A, 8.5 ± 1.8 s; group B, 7.8 ± 0.7, p = 0.11). At the scheduled visits, TBUT increase vs screening visit was significantly higher in group A: +1.2 s at V0, +1.4 s at V1, and +1.9 s at V2 (p < 0.01). Also, OSDI was significantly lower in group A at V0, V1, and V2 (p < 0.027). After surgery, corneal staining was absent in 65-78% of group A compared with 54-59% in group B. The two groups did not show any significant differences of osmometry and the Schirmer I test. CONCLUSIONS The ocular surface was more protected and quickly restored from surgery when VisuEvo® was used from 2 weeks preoperatively to 2 weeks postoperatively.

Impact of 0.1% sodium hyaluronate and 0.2% sodium hyaluronate artificial tears on postoperative discomfort following cataract extraction surgery: a comparative study. EYE AND VISION 2019; 6:6. [PMID: 30805405 PMCID: PMC6373058 DOI: 10.1186/s40662-019-0131-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/21/2018] [Accepted: 01/27/2019] [Indexed: 12/14/2022]
Abstract
Background Recent artificial tear preparations have provided 0.2% concentration of sodium hyaluronate. However, no published data exist on their potential superiority against 0.1% in alleviating dry-eye-disease symptoms in cataract extraction surgery. Methods A total of 180 patients that underwent cataract extraction surgery were randomly divided into 2 groups according to their postoperative regime: Study group (SG) received fixed combination of tobramycin and dexamethasone (FCTD) quid for 3 weeks, and additionally 0.2% sodium hyaluronate provided in the COMOD® device quid for 6 weeks. Control group (CG) received fixed combination of tobramycin and dexamethasone (FCTD) quid for 3 weeks, and additionally 0.1% sodium hyaluronate provided in the COMOD® device quid for 6 weeks. The following indexes were evaluated at 3 postoperative checkpoints: 1) Surface discomfort index (SDI) which was derived by four direct 10-scale Likert-type questions that were addressed to the patient and pertained to: a) foreign body sensation (FBS), b) blinking discomfort (BD), c) stinging sensation (SS), d) tearing sensation (TS), 2) Tear break-up time (TBUT), 3) Schirmer’s test, 4) Central corneal thickness (CCT), and 4) Central Corneal Sensitivity (CCS). Results Both groups showed reduced CCS values at all postoperative examination points; however, SG participants had significantly better CCS (all p < 0.05). SG had better TBUT than CG at the 3rd (p = 0.03) and 6th examination points (p = 0.04). Moreover, SG had better SDI scores at the 3rd (SDI = 9.26 ± 0.55) and 6th weeks (SDI = 9.47 ± 0.48) vs. CG participants (p = 0.03 and p < 0.01, respectively). Conclusion The increased 0.2% sodium hyaluronate concentration in the artificial tears provided in the COMOD® device seems to address dry-eye-disease symptoms better in patients who underwent phacoemulsification surgery than the 0.1% concentration.
