RESUMO
Purpose: To understand the impact of Systane Hydration PF on dryness symptoms and quality of life in digital device users and to determine if participants prefer either the unit-dose or multi-dose dispensing system of Systane Hydration PF. Materials and Methods: This 2-week, three visit study recruited regular digital device users. Participants were required to score ≤80 on the Impact of Dry Eye on Everyday Life (IDEEL) Quality of Life (QoL) Work domain and between 13 and 32 on the Ocular Surface Disease Index (OSDI) questionnaire. Participants were randomized to either Systane Hydration PF unit-dose or multi-dose for 1 week and switched to the alternative dosing system for the second week. Participations were evaluated by completing the full IDEEL-QoL module and OSDI questionnaire at each visit. Likert surveys were completed to probe dispensing system preferences. Results: Thirty participants with a mean ± SD age of 28.6 ± 12.0 years (70% female) were recruited. Participants had significant improvements in all three IDEEL-QoL domains as well as in OSDI scores (all p < 0.0001). Participants had similar preferences for the two dispensing systems, though they were more likely to indicate that they thought that the multi-dose bottle was more environmentally friendly than the unit-dose vials. Conclusion: Digital device users with dry eye symptoms had meaningful improvements in eye comfort and quality of life scores after being treated with Systane Hydration PF for 2 weeks. Participants did not have a clear dispensing system preference suggesting that the best dispensing system may depend on the patient.
RESUMO
BACKGROUND: Presbyopia is the age-related decline in accommodation that diminishes the ability of the eye to focus on near objects. Presbyopia is common and easy to correct; however, many communities lack access to basic eye care. The purpose of this project was to assess the burden of uncorrected presbyopia in a rural Filipino population and to pilot an intervention aimed at increasing access to reading glasses in the community. METHODS: Individuals above the age of 40 who presented to a health outreach in the Philippines were invited to undergo a near vision exam to detect the presence of functional presbyopia and be fitted with ready-made, single-vision glasses. The change in stereoacuity was used as a surrogate measure of functional improvement after near vision correction. A questionnaire was administered to assess this population's perceived barriers and benefits to correcting near vision. RESULTS: The average age of the participants was 57 ± 11 years, with 87.6% of participants having an uncorrected near visual acuity of <20/50. Reading glasses improved near vision to 20/40 or better in 77.7% of participants having near-vision impairment (uncorrected near visual acuity of <20/40). Over 75% of participants also showed improvement in stereoacuity. Cost, rather than availability, was perceived to be the greater barrier to the procurement of glasses, and 84% of participants reported that the glasses dispensed would greatly improve their ability to earn a living. CONCLUSIONS: Dispensing ready-made, single-vision glasses is a simple and cost-effective intervention to improve near vision and enhance depth perception. A greater understanding of the barriers and benefits to correcting near vision will inform the design and execution of a sustainable program to correct presbyopia in developing countries.

We used data from two pilot studies to compare the change in patients' self-reported health-related quality of life after participation in two nearly identical Department of Veterans Affairs (VA) Blind Rehabilitation Center (BRC) programs, the Southwestern BRC in Tucson, Arizona, and the BRC at the VA hospital in Hines, Illinois. Researchers at the Southwestern BRC administered the National Eye Institute Visual Functioning Questionnaire as directed by the developer. Researchers at the Hines BRC modified the directions to consider use of low-vision devices. Interval person-ability and item-difficulty measures estimated from patient responses pre- and postrehabilitation were compared with these same measures obtained at follow-up. At the Southwestern BRC, no change was reported in either person or item measures 3 months after rehabilitation. At the Hines BRC, improvement was seen in both the person and item measures when measurements were made immediately following rehabilitation. Because a temporary halo effect may explain the higher ratings at discharge, veterans from the Hines cohort were contacted by telephone and administered the same instrument 3 years later. For these subjects, the improvement noted in the person measure disappeared at follow-up, while the improvement in the item measure was maintained.
