Demographic profiles of contact lens wearers and their association with lens wear characteristics in Trinidad and Tobago: A retrospective study

Purpose C ontact lenses (CL) remain a popular mode of refractive error correction globally and in the Caribbean, mostly among young people. However, no data on the characteristics of the CL population wearers in the Caribbean is available. This study reported on the characteristics of CL wearers and the associated factors in Trinidad and Tobago (T&T). Methods Clinical records of 243 CL wearers attending the University of the West Indies (UWI) optometry clinic between 2017 and 2018 were reviewed. Data on their demographic profiles, CL wearing characteristics including lens type, material, purpose of wear, replacement schedule and care systems were extracted and analyzed. The associations between the demographic characteristics and CL wearing characteristics were also determined. Results About half of the respondents wear CL wearers and used them for various purposes such as fashion (more among those aged 18 to 30 years, 61.0%), therapeutic (more among those 40 years, P =0.001). Females were more likely to use CLs for fashion compared with males (67.0% versus 40.7%). Age ( P <0.0005) and gender ( P =0.030) were associated with the lens materials. Those aged 18-30 years were more likely use hydrogels compared with the younger ones (64.1% versus 25.0%). Rigid gas permeable (RGP) CL use was more common in males than females (21.8% versus 10.9%, P = 0.031). Daily disposables were predominantly used by younger respondents (18-30 year-olds, 31.3%, P < 0.001) and more in females than males (66.7% vs 49.4%, P = 0.040). Conclusions Contact lens use appears be more common among younger females for fashion and older males for refractive correction. Age, gender and employment status were the main determinants of lens wear among respondents attending the university clinic in T&T.
