This article is part of Ophthalmology Advisor’s conference coverage from the 2021 meeting of American Society of Cataract and Refractive Surgery (ASCRS), held in Las Vegas from July 23 to 27, 2021. The team at Ophthalmology Advisor will be reporting on a variety of research presented by the cataract and refractive surgery experts at ASCRS. Check back for more from the ASCRS 2021 Meeting.


After undergoing immediately sequential bilateral cataract surgery (ISBCS), 99% of patients were seeing 20/40 or better, uncorrected, in at least 1 eye at postoperative week 1 (POW1), according to findings presented at the American Society of Cataract and Refractive Surgery (ASCRS) annual meeting, held in Las Vegas from July 23 to 27.

Researchers conducted a retrospective chart review to evaluate ISBCS patients’ postoperative visual recovery. The study evaluated patient data (n=100) from surgeries between January and November 2019 (200 eyes total). Inclusion data consisted of uncorrected distance visual acuity (UDVA) for postoperative day 0/1 (POD0/1), POW1, and postoperative month 1 (POM1). Patients with ocular comorbidities were not excluded from the study; however, all patients passed initial screening to qualify for ISBCS.

The study’s main outcome measures were POD0/1, POW1, and POM1 UDVA. The researchers found that 185 out of 200 eyes (92.5%) had a UDVA of at least 20/40 at POW1. Of the 15 eyes with a UDVA worse than 20/40, 5 were known preoperatively to have limited visual potential. 100% of patients (99/99) had at least 1 eye 20/40 or better at POW1, excluding 1 patient with preexisting bilateral macular disease. Stable or improved UDVA was demonstrated in 66% (53/80) of patients compared with preoperative corrected distance visual acuity (CDVA) at POD1; in 86% (49/57) at POW1; and in 98% (134/137) at POM1, excluding eyes with 20/20 preoperative CDVA.

The researchers note that there is currently a paucity of data around questions of postoperative expectations for patients considering ISBCS surgery, and they expect these results to better guide clinicians when discussing this topic with patients.
