Abstract
BACKGROUND: This paper fills a gap in the applied research field, for a local context, by addressing the topics of describing cataract surgery' clinical outcomes; quality of life (QoL); and costs of the patients treated after the implementation of the ICHOM standard set. METHODS: This is a retrospective observational study using real-world data (RWD). We included all patients subjected to cataract surgery at the Portuguese Institute of oncology - Porto (IPO-Porto), Portugal, after 3 months follow up period completed between 5th June 2017 and 21st May 2018. The following inclusion criteria: corrected visual acuity of ≤ 6/10 or other significant visual disturbance due to lens opacity or the existence of a large anisometropia. A circuit was implemented based on the ICHOM standard for cataract, to measure clinical variables (e.g. visual acuity) and QoL (CATQUEST-9SF) before and after surgery, and cost of treatment. The results were explored by means of a paired-sample t-test, considering normality assumptions. RESULTS: Data refers to 268 patients (73 P25-P75:32-95 years old), regarding 374 eyes. The cataract surgery had a positive effect on visual acuity (p < 0.001), refraction (right and left cylinder; p < 0.001) and all QoL dimensions. The vast majority of patients, around 98%, reported improvements in QoL. Based on IPO-Porto administrative records, the direct cost of treating cataracts (per eye) is of 500€, representing a total cost of 187,000€ for the number of patients operated herein. CONCLUSION: This study reports the successful implementation of the ICHOM standard set for cataracts in a Portuguese institution and confirms that cataract surgery provides a rapid visual recovery, with excellent visual outcomes and minimal complications in most patients, while also having a positive impact on patients' quality of life.
