In the journal: January/February 2020 Clinical factors affecting operating room utilization in cataract surgery: results from the PCIOL study K. Matthew McKay, MD, Durga Borkar, MD, Giannis Moustafa, MD, Miriam Haviland, MSPH, Carolyn Kloek, MD, the PCIOL Study Group A large-scale, retrospective cohort study out of the Comprehensive Ophthalmology unit at Massachusetts Eye and Ear Infirmary found that preoperative clinical patient characteristics and surgeon identity significantly correlated with operative time. The investigators theorized that "incorporating these results into predictive algorithms may allow for more predictable surgical scheduling and more efficient use of operative resources." The analysis included 1,349 cataract surgeries from 1,072 patients with a mean operative time of 22.1±7.8 minutes. "In the multivariate model with surgeon identity, longer operative time was associated with male gender, increased BMI, first eye surgery, left operative eye, advanced cataract, use of iris hooks, use of Malyugin ring, use of trypan blue, history of diabetic retinopathy, short axial length, and shallow anterior chamber depth," the investigators wrote.

The study obtained information from public institu- tions and private ophthalmologists in France through questionnaires. Thirty-three question- naires were included in the final analysis, corresponding to 65 eyes relevant to the study. Of these eyes, 60 experienced complications. According to the research the most common complication was corneal decompensation (78.5%). Glaucoma was diagnosed in 52.3% of eyes and explantation occurred in 81.5% of cases. There was decreased mean visual acuity, with a mean final visual acuity 0.45 ± 0.08 logMAR (0-2 logMAR). The authors said safety information about the procedure for the patient "appeared insufficient." The association between cataract and cotinine-verified smoking status in 11,435 Korean adults using Korea National Health and Nutrition Examination Survey data from 2008 to 2016 Hae Jeong Lee, MD, Cheol Hong Kim, MD, Ju Suk Lee, MD, Sung Hoon Kim, MD Retrospective data analysis investigated the association between smoking, including "hidden" smokers, and cataract. The investigators used "cotinine-verified smoking status" as a new variable to define smoking status. The analysis included 11,435 Korean adults. Of the 4,925 men and 6,510 women, 2,292 were cotinine-verified smokers, 382 of whom self-reported as nonsmokers. "Notably, the ratio of cotinine-verified to self-reported smoking rate of women was greater than that of men, 1.60 and 1.06, respectively," the authors wrote. "This indicated that female hidden smokers may affect the results of studies based on the self-reported ques- tionnaires." Analysis showed that smoking was correlated with having cataracts and gender was not a factor. REGISTER TODAY!
