Impact of Free Reading Glasses on Work and Visual Function Following Cataract Surgery in Honduras: The POWER Trial (Post-Operative Work-Related Effect of Reading Glasses)
Cataract surgery improves vision and is therefore assumed to improve a person's ability to work and function. Following cataract surgery, most patients do not need glasses to see clearly at distance, but they do require glasses to see clearly up close. If a patient is unable to acquire reading glasses after surgery due to either financial or logistical reasons, their ability to resume work and functioning may be compromised, diminishing the overall benefit to be gained from cataract surgery. Patients in the developing world may be affected disproportionately due to difficulty accessing care postoperatively. In this study, patients receiving cataract surgery at a clinic in Comayagua, Honduras will be randomized to either receive free reading glasses immediately after surgery or four months later. The primary outcome is the proportion of subjects who report that vision interferes with their ability to work. Secondary outcomes will include the number of hours worked each week at productive activities, income level, and visual functioning. The hypotheses are that the patients who receive free reading glasses immediately following surgery will be less likely to report that their vision interferes with their ability to work, they will work at productive activities a greater number of hours each week, their incomes will be higher, and their visual function scores will be higher.
