Abstract

Significance: No information is available on contact lens discomfort in any African population. Such information may be helpful in developing the scope and priorities for intervention.

Purpose: The purpose of the study was to examine contact lens- and patient-related factors associated with contact lens discomfort among wearers in Ghana.

Methods: In this multicenter cross-sectional study, contact lens wearers 18 years and older were recruited. The Contact Lens Dry Eye Questionnaire-8 and a standardized scripted interview were administered to 72 contact lens wearers at five clinical sites, and 40 participants' lens storage cases were collected and cultured. A variety of patient- and contact lens-related factors were examined. Univariate and multivariate logistic regression modeling were used to assess risk factors associated with contact lens discomfort.

Results: Seventy-two contact lens wearers aged 18 to 45 years completed the study. The mean age was 27.5 ± 6.4 years, 65.3% of them were females, 86.1% wore soft contact lens, and 13.9% wore rigid gas-permeable lens. Contact lens discomfort was reported by 66.7% of the subjects. Most frequent lens storage cases isolates were Bacillus species (40%) and fungi (31.1%). Significant association was found between disinfecting with tap water (5.98; 95% confidence interval [CI], 1.22 to 29.27; P = .03), heavy visual display terminal use (3.39; 95% CI, 1.01 to 11.34; P = .05), high water content (1.16; 95% CI, 1.02 to 1.33; P = .03), and contact lens discomfort. Demographic factors, wear modality, and care solutions were not significant (all P > .05).

Conclusions: In considering the use of contact lenses for refractive correction in this population, strategies for preventing contact lens discomfort that should be targeted include use of low-water-content lenses, disinfecting with multipurpose solutions, and reducing the time spent daily on visual display terminal use.
