Immediately sequential bilateral cataract surgery can be safely conducted following the same guidelines as sequential bilateral cataract surgery, according to a study presented at the American Academy of Ophthalmology 2021 meeting, held in New Orleans November 12-15.

Researchers at Laval University in Quebec City, Canada reviewed the cases of 4006 eyes of 2003 consecutive patients (mean age 74±8 years, 60.8% women) who underwent immediately sequential bilateral cataract removal under local anesthesia between January 2019 and December 2019. Participants had a mean preoperative visual acuity of 0.503 logMAR (Snellen 20/63). 

Patients were implanted with 1 of 4 kinds of intraocular lenses (IOLs); 3738 eyes (93.3%) received monofocal IOLs, 226 eyes (5.6%) received toric IOLs, 25 eyes (0.6%)  received multifocal IOLs, and 17 eyes (0.4%) received multifocal toric IOLs. None of the participants developed endophthalmitis, or toxic anterior segment syndrome, according to the report.

In total, 2 postoperative complications were noted, posterior capsule ruptures, which occurred in 14 eyes (0.3%) , and 7 eyes (0.2%) developed zonulysis. 

The patients’ mean postoperative uncorrected visual acuity after 7 weeks was 0.223 logMAR (Snellen 20/33), while pinhole visual acuity was 0.153 (Snellen 20/28) with a mean spherical equivalence of -0.21 D.
