“However, more recent studies have demonstrated that this incidence rate may be declining.” The incidence rate observed in the present study also provides evidence of this trend. “Prior studies (before modern-day small-incision cataract surgery) have reported the one-year incidence of RRD after cataract surgery to range from 0.6% to 1.7%, representing a more than 30-fold increased risk of RRD when compared with rates in the general population of 0.007% to 0.018%,” the researchers wrote in their paper. Within one year of the procedure, 0.21% of the cohort developed RRD–equating to one in 500 cataract surgeries–and 0.17% developed retinal tear without RRD. The retrospective cohort study included 3,177,195 eyes of 1,983,712 patients from the registry, all of whom were at least 40 years old (90% over 60 and 52% over 70) and underwent cataract surgery between 20. The researchers identified certain demographics, ocular comorbidities and intraoperative factors that appeared to increase the likelihood of these events, including male gender, younger age, lattice degeneration, hypermature cataract, posterior vitreous detachment (PVD) and high myopia.

Patients who are more likely to develop retinal detachment or retinal tear after cataract surgery include those with male gender, younger age, lattice degeneration (pictured), hypermature cataract, posterior vitreous detachment and high myopia, study finds.
