ObjectiveDetermine whether items in a cataract surgery appropriateness and prioritization questionnaire can predict change in best corrected visual acuity (BCVA) and health related quality of life (HRQOL) following cataract surgery.Methods313 patients with a cataract in Ontario, copyright were recruited to participate.BCVA was measured using the Snellen chart.HRQOL was measured using a generic instrument (EQ5D), a visual functioning iphone xr price calgary instrument (Catquest-9SF), and an appropriateness and prioritization instrument (17 items).
Outcomes were measured preoperatively and 3-6 months postoperatively.Descriptive statistics were used to describe demographics and outcomes.For each appropriateness and prioritization questionnaire item, a one-way ANOVA was used to compare group means of the change in BCVA, EQ5D, and Catquest-9SF.ResultsParticipants had a mean age of 69 years and were 56% female.
BCVA improved in 81%, EQ5D in 49.6%, and Catquest-9SF score in 84% of patients.Improvement in both BCVA and Catquest-9SF scores were found in 68.5% of patients.
The ANOVA showed a statistically significant association between a change in BCVA and the ability to participate in social life, and a statistically significant association between a change in Catquest-9SF and glare, extent of impairment in visual function, safety and injury concerns, ability to work and care for dependents, ability equi-jec 6 to take care of local errands, ability to assist others and ability to participate in social life.ConclusionsAlmost all patients had improved BCVA and/or visual functioning after surgery.Seven variables from the cataract appropriateness and prioritization instrument were found to be predictors of improvement in Catquest-9SF measuring visual functioning.
