Abstract
PURPOSE To explore the impact of subjective factors (lens handling, comfort and vision) on overall single vision contact lens satisfaction. METHODS Correlation analysis of a prospective, randomised, double-masked, bilateral crossover study involving 55 adapted lens wearers fitted with somofilcon A (SiHy) (clariti® 1 day, CooperVision) and etafilcon A (Hy) (1 DAY ACUVUE® MOIST, Johnson & Johnson Vision) was conducted. Subjective ratings of lens handling, comfort and vision collected after 1 week of lens wear for each lens type were correlated with overall satisfaction. Data were analysed by combining data for both lens types and also for each lens separately. RESULTS For the combined analysis, significant correlations (p < 0.01) were found between subjective ratings of overall satisfaction and ratings of handing for application (r = 0.64), handling for removal (r = 0.50), comfort upon application (r = 0.59), comfort at end of day (r = 0.61), overall satisfaction with comfort (r = 0.88) and overall satisfaction with vision (r = 0.64). Correlation analysis of the per lens data showed that lens specific correlations of overall satisfaction with handling for lens application varied greatly with lens material (SiHy: r = 0.26, p = 0.05 vs Hy: r = 0.72, p < 0.01). Correlation strength of comfort upon application/at end of day with overall satisfaction also varied with lens material (Application: SiHy: r = 0.40 vs Hy: r = 0.61; End of day: SiHy: r = 0.76 vs Hy: r = 0.58; all p ≤ 0.01). CONCLUSION Overall satisfaction was significantly correlated with the specific subjective evaluations of handling, vision and comfort. Correlations of overall satisfaction and ease of handling for each lens type suggest that, for habitual contact lens wearers, dissatisfaction with handling at the time of lens application can play a major role in overall dissatisfaction with a lens. Handling for application had a similar correlation (r) value as vision, suggesting that handling for application should not be underestimated when considering overall patient satisfaction.

Abstract
PURPOSE To evaluate the comfort performance of ACUVUE OASYS® 1-Day with HydraLuxe™ Technology among symptomatic contact lens wearers by using Contact Lens User Experience (CLUE) comfort scores and Contact Lens Dry Eye Questionnaire 8 (CLDEQ-8) discomfort and dryness scores. METHODS Three clinical trials evaluated comfort and dryness when refitting symptomatic contact lens wearers to ACUVUE OASYS® 1-Day with HydraLuxe™ lenses. This analysis combined the CLUE comfort and CLDEQ-8 scores obtained at baseline and 2-week follow-up and compared average scores between visits. Subjects were grouped by habitual lens modality (daily disposable or daily wear reusable) and habitual lens material (silicone hydrogel or hydrogel). The analysis included data from 107 subjects. RESULTS Significant increases in mean CLUE comfort scores between baseline and 2-week follow-up occurred in all subject groups across habitual lens modality and material, indicating an improvement in overall comfort. CLUE comfort score improved clinically (≥5-point increase) among 75.7% of subjects (81/107). Similarly, significant decrease in mean CLDEQ-8 scores between baseline and 2-week follow-up occurred in all subject groups, indicating a decrease in the prevalence of dryness and discomfort symptoms. CLDEQ-8 score improved clinically (≥3-point reduction) among 82.2% of subjects (88/107). A majority of subjects (57.0%) became asymptomatic (CLDEQ-8 score ≤ 11 points) after 2 weeks of bilateral wear. CONCLUSION Refitting symptomatic contact lens patients to ACUVUE OASYS® 1-Day with HydraLuxe™ can improve overall comfort and reduce symptoms of dryness and discomfort, irrespective of the previous lens modality or habitual lens material.

Abstract
Ocular drug delivery has always been a challenging feat to achieve in the field of medical sciences. One of the existing methods of non-invasive ocular drug delivery is the use of eye drops. However, drugs administered through these formulations have low bioavailability in the ocular system. This limitation can been overcome by using contact lenses as drug delivery vehicles. According to USA FDA definitions they can be categorized into two main categories-hard and soft contact lenses. Based on the material properties, hard contact lenses are mostly produced from polymers of acrylate monomers such as MMA (methyl methacrylate). These have the least water retention capacity, thereby, having minimal ability to diffuse oxygen into the corneal layer and are not ideal for long term use. Soft material contact lenses are flexible and are mainly hydrogel based. They have higher water retention capacities as compared to rigid contact lenses, which gives them the ability to transmit oxygen to the corneal layer. These hydrogel based soft materials are mainly produced from polymers of acrylate monomers such as HEMA (hydroxyethyl methacrylate) and found to be better for drug delivery contact lenses. These polymer-based soft materials have been efficiently modified in terms of their chemistry to achieve diverse physicochemical properties to produce efficient ocular drug delivery systems. However, complications such as drug leaching during storage and distribution, sterilisation, preservation of integrity of the lens and the possibility of surface roughness due to the incorporated drug molecules still need to be optimised. This review highlights the chemistries of various polymeric molecules through which physicochemical properties can be modified to achieve optimum drug loading and sustained release of the drug for application in the ocular system. Contact lens as controllable route for ocular drug delivery.![]()

Thickness changes in the corneal epithelium and Bowman's layer after overnight wear of silicone hydrogel contact lenses. BMC Ophthalmol 2018; 18:286. [PMID: 30390645 PMCID: PMC6215685 DOI: 10.1186/s12886-018-0956-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Accepted: 10/24/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To investigate thickness changes in the corneal epithelium and Bowman's layer after overnight silicone hydrogel contact lens (CL) wear by using ultra-high resolution optical coherence tomography (UHROCT). METHODS Eleven subjects without CL wearing history were recruited for this study. An UHROCT was used to measure the thickness of the epithelium (ET), Bowman's layer (BT), stroma (ST), and total cornea (CCT) at the center of both eyes. A silicone hydrogel CL was inserted in the right eye of each subject, and the fellow non-CL wearing left eye served as the control. The lens was inserted at 9:30 pm and removed at 8:00 am the next morning. The subjects were evaluated at 9:00 pm (baseline), 9:30 pm (lens insertion), 10:00 pm (before sleep), 7:00 am (waking), 7:30 am, and 8:00 am (lens removal). RESULTS Compared to the lens insertion level, the ET of the lens-wearing eye increased by 5.73% at eye opening (P = 0.001). The ET of the non-CL wearing eye and the BT in both eyes did not change after overnight CL wear. Compared to baseline, the CCT of the lens-wearing eye increased by 2.87% upon waking (P = 0.003) and recovered 30 min later (P = 0.555). In contrast, compared to baseline, the CCT of the non-CL wearing eye did not increase upon waking (P = 0.105). CONCLUSIONS By using UHROCT, we found that overnight CL wear induced different swelling responses in the various sublayers of the cornea. TRIAL REGISTRATION Retrospectively registered.

Abstract
PURPOSE To test the ability of responses to the Contact Lens Assessment in Youth (CLAY) Contact Lens Risk Survey (CLRS) to differentiate behaviors among participants with serious and significant (S&S) contact lens-related corneal inflammatory events, those with other events (non-S&S), and healthy controls matched for age, gender, and soft contact lens (SCL) wear frequency. METHODS The CLRS was self-administered electronically to SCL wearers presenting for acute clinical care at 11 clinical sites. Each participant completed the CLRS before their examination. The clinician, masked to CLRS responses, submitted a diagnosis for each participant that was used to classify the event as S&S or non-S&S. Multivariate logistic regression analyses were used to compare responses. RESULTS Comparison of responses from 96 participants with S&S, 68 with non-S&S, and 207 controls showed that patients with S&S were more likely (always or fairly often) to report overnight wear versus patients with non-S&S (adjusted odds ratio [aOR], 5.2; 95% confidence interval [CI], 1.4-18.7) and versus controls (aOR, 5.8; CI, 2.2-15.2). Patients with S&S were more likely to purchase SCLs on the internet versus non-S&S (aOR, 4.9; CI, 1.6-15.1) and versus controls (aOR, 2.8; CI, 1.4-5.9). The use of two-week replacement lenses compared with daily disposables was significantly higher among patients with S&S than those with non-S&S (aOR, 4.3; CI, 1.5-12.0). Patients with S&S were less likely to regularly discard leftover solution compared with controls (aOR, 2.5; CI, 1.1-5.6). CONCLUSIONS The CLRS is a clinical survey tool that can be used to identify risky behaviors and exposures directly associated with an increased risk of S&S events.

Abstract
Chemical injuries frequently result in vision loss, disfigurement, and challenging ocular surface complications. Acute interventions are directed at decreasing the extent of the injury, suppressing inflammation, and promoting ocular surface re-epithelialization. Chronically, management involves controlling inflammation along with rehabilitation and reconstruction of the ocular surface. Future therapies aimed at inhibiting neovascularization and promoting ocular surface regeneration should provide more effective treatment options for the management of ocular chemical injuries.

Abstract
Dry eye is a common ocular surface disease of multifactorial etiology characterized by elevated tear osmolality and inflammation leading to a disrupted ocular surface. The latter is a risk factor for ocular surface infection, yet overt infection is not commonly seen clinically in the typical dry eye patient. This suggests that important innate mechanisms operate to protect the dry eye from invading pathogens. This article reviews the current literature on epidemiology of ocular surface infection in dry eye patients and laboratory-based studies on innate immune mechanisms operating at the ocular surface and their alterations in human dry eye and animal models. The review highlights current understanding of innate immunity in dry eye and identifies gaps in our knowledge to help direct future studies to further unravel the complexities of dry eye disease and its sequelae.

Abstract
The current literature review was intended to investigate whether the use of silicone hydrogel contact lenses has resulted in improved comfort compared with that of hydrogel contact lenses when both are used for daily wear. The conclusion reached is that silicone hydrogel contact lenses, which were initially developed to eliminate hypoxia during overnight wear, have not significantly improved comfort compared with the comfort achieved with hydrogel contact lenses when worn on a daily wear basis, even though a body of the published literature would suggest to the contrary. A careful review and consideration of the literature demonstrates that the relative comfort achieved with the two types of contact lenses is in fact highly dependent on the study methodology: Although refitting studies have concluded enhanced comfort with silicone hydrogels, the more robust study designs involving concurrent controls and masking were not able to show a difference, and some even concluded an inferior performance. Evidence-based review has however clearly demonstrated that comfort cannot be considered in isolation but is contact lens specific and depends on the material surface and bulk properties, lens design characteristics, and modality of use of the contact lens, and may also be significantly influenced by the replacement frequency and interaction with any lens care system that may be used.

Abstract
PURPOSE To evaluate the safety, physiological performance, and effect on ocular tissues of a new multipurpose disinfecting solution (MPDS) specifically formulated for use with silicone hydrogel (SH) contact lenses (CL). METHODS Two MPDS [solution A (Solo-care Aqua(®), Ciba-Vision) and solution B (Hidro Health(®), Disop)] were randomly assigned and prescribed in a clinical trial in a crossover clinical trial (Registered #293/07/EC; Spanish National Health Department). Only lotrafilcon B CL daily wearers were included. After each solution was used, a masked investigator assessed the slit-lamp findings (SL9, Topcon Inc.), lens deposits, and wettability according to the Guidance for clinical investigation (ISO 11980). CL daily wearing time (hours per day and days per week) were recorded. RESULTS Fifty-four daily wearers were included. Average CL wear time was 8.3 ± 2.3 (CI95% 7.9-8.7) hours per day (8.5 ± 2.7 at baseline visit, 8.2 ± 1.9 with solution A, and 8.4 ± 2.2 with solution B). The average number of days per week of CL wear was 5.9 ± 1.3 (CI95% 5.6-6.1) (5.4 ± 1.6 at baseline visit, 6.1 ± 0.9 with solution A, and 6.0 ± 1.1 with solution B). Non-adverse slit-lamp findings were recorded (higher than 2 points). No statistical difference (P>0.05 Friedman test) in CL wearing time, number of days of CL wears and slit-lamp findings were found between the two solutions. CONCLUSIONS This clinical trial shows that the new formulation of Hidro Health(®) MPDS is safe when used for the care of daily-wear lotrafilcon B CL. This new solution has no clinical significance on ocular tissues, according to the Guidance for clinical investigation (ISO 11980).

Abstract
OBJECTIVE Demonstrate that successful soft contact lens wearers using competitive multipurpose solutions report improvement in comfort with OPTI-FREE((R)) RepleniSH((R)) Multi-Purpose Disinfecting Solution (MPDS). METHODS This 30-day, multicentered, open-label study enrolled 109 eligible soft contact lens wearers using COMPLETE((R)) Multi-Purpose Solution (MPS) Easy Rub((R)) or ReNu MultiPlus((R)) MPS. The test solution (OPTI-FREE((R)) RepleniSH((R)) MPDS) was dispensed for use in place of habitual care solutions. Subjects assessed their experience with their habitual solution (baseline) and the test solution (Day 30) using Likert-style questions. Contact lens acuity and biomicroscopy findings were recorded at each visit. RESULTS The test solution was associated with a statistically significant improvement in instillation comfort (P = 0.02), end of day comfort (P < 0.0001), clear vision (P < 0.0001) and overall satisfaction (P < 0.001). Subjects reported the test solution enhanced their overall lens-wearing experience more effectively than their previous solution (P < 0.0001) and that they would continue test solution use after the study (P < 0.0001). CONCLUSIONS The test solution was effective at improving comfort and overall contact lens experience compared to COMPLETE((R)) MPS Easy Rub((R)) or ReNu MultiPlus((R)) MPS in successful contact lens wearers. These results indicate that changing contact lens care solutions, even in successful lens wearers, may improve comfort and overall lens-wearing experience.

Abstract
BACKGROUND The rate and reasons for discontinuation of contact lens wear by young patients are not well known. The Contact Lenses in Pediatrics (CLIP) Study surveyed participants 3 months after the final study visit to determine the percentage of participants who continued to wear contact lenses after study conclusion. The factors associated with continued contact lens wear and differences in behaviors between the children and teens were also determined to provide insights to practitioners who provide refractive correction for patients in those age groups. METHODS Three months after the CLIP Study completion, participants and parents returned mailed surveys that assessed post-study lens purchase and symptoms related to contact lens wear if contact lenses wear had been continued. Responses were compared between the children and teens using chi(2) or Fisher's exact test. RESULTS Almost 92% of the surveys were returned. Eighty percent of teens' parents reported purchasing lenses after the study, vs. 63% of the children's parents (p=0.02). Symptoms reported at the last study visit were not significantly associated with future purchase, though there was a trend towards more light sensitivity in those who did not purchase more contact lenses (23.1% vs. 11.8%). Satisfaction with contact lenses was high among both those purchasing additional contact lenses and those who did not. Both children and teens reported similar frequencies of symptoms such as burning, itching or tearing eyes 3 months following study completion. Teens reported having contact-lens-related dry eyes more frequently than children. CONCLUSIONS A large proportion of children and an even higher proportion of teens continued wearing their lenses 3 months after completing the CLIP Study. Children and teens reported similar contact lens comfort and low frequencies of most symptoms, though teens experienced more dry-eye symptoms. Overall, reports of symptoms in this sample were lower than had been reported in adult populations by other investigators.
