ABSTRACT (max. 250)
To evaluate the safety and outcomes of immediately sequential bilateral cataract surgery (ISBCS) at a Canadian academic teaching center.
Tertiary university teaching hospital of Laval University, Quebec City, Canada.
Retrospective cohort study of 2003 consecutive patients (4006 eyes) who underwent ISBCS under topical anesthesia from January 2019 to December 2019.
All charts were retrospectively reviewed. Outcome measures included intraoperative and postoperative complications, postoperative uncorrected (UCVA) and pinhole (PHVA) visual acuities, and autorefraction measurements.
1218 (60.8%) female and 785 (39.2%) male patients with a mean age of 74 ± 8 years old had a mean preoperative visual acuity of 0.503 LogMAR (Snellen 20/63). The mean axial length was 23.53 ± 1.37 mm. The majority of eyes had monofocal intraocular lenses (IOL) implanted (n=3738, 93.3%) followed by toric (n=226, 5.6%), multifocal (n=25, 0.6%), and multifocal toric (n=17, 0.4%) IOLs. Intraoperative complications included 14 (0.3%) posterior capsule ruptures with 5 (0.1%) requiring sulcus IOL placement, and 7 (0.2%) partial zonulysis, with 3 requiring capsular tension rings (0.07%). There were no cases of endophthalmitis or toxic anterior segment syndrome. Mean 5-week postoperative UCVA was 0.223 (Snellen 20/33), PHVA was 0.153 (Snellen 20/28) with a mean spherical equivalent of -0.21 diopters.
ISBCS performed following iSBCS recommended guidelines is a safe procedure. This cohort of 4006 eyes had very few complications, with none attributable to the surgery being done bilaterally. The UCVA, PHVA and refractive outcomes were good.
