Return of phacoemulsification after emergency status related to COVID-19: experience of a tertiary referral center

Abstract

Purpose: To present a protocol of priority criteria for phacoemulsification after the backlog due to severe acute respiratory syndrome coronavirus (SARS-CoV)-2 pandemic status. Setting: Ophthalmology department of Centro Hospitalar e Universitário do Porto (CHUP), Oporto, Portugal. Design: Cross-sectional, nonrandomized, retrospective study. Methodology: Data of all patients waiting for cataract surgery were analyzed at the beginning of May 2020, after 2 months without performing elective surgery. The waiting time since surgical inscription was considered an independent and overriding factor. In addition, higher priority was given to patients with white or brunescent cataracts and patients with low visual acuity: corrected distance visual acuity (CDVA) of 20/200 or less in binocular patients or CDVA of 20/63 or less in monocular patients. Criteria of medium priority included patients who remained with anisometropia and patients with glaucoma or low to moderate risk for chronic angle closure. Data of scheduled surgeries in the following months were then analyzed. Results: A total of 717 patients were waiting for phacoemulsification. One hundred ninety-one patients (26.64%) were on the waiting list more than 4.5 months; the medium waiting time was 3.51 ± 1.57 months. According to both priority criteria and waiting time, 348 (48.6%) were categorized as priority cases. A total of 158 patients (22.0%) met the highest priority; 61 patients (8.5%) met the medium priority criteria. In 129 patients (18.0%), priority was considered based solely on higher waiting time. This algorithm allowed surgeons to operate on all priority cases within the first 3 months. Conclusions: The presented protocol showed to be effective, providing a timely surgical opportunity for priority cases.
