In the past 5 years, we experienced 14 cases of lens injury in pars plana vitrectomy. The appliances causing those injuries were vitreous probe (12 eyes), infusion cannula (1 eye) and vitreous forceps (1 eye). These were classified into 3 groups according to clinical elapse. In group 1 (4 eyes), cataract progress and uveitis occurred simultaneously. In group 2 (6 eyes), cataract progress alone occurred. In group 3 (4 eyes), cataracts remained localized. In groups 1 and 2, lenses were extracted. Group 1's prognoses were extremely bad. When cataract progresses rapidly after lens injury, prompt lens extraction prevents lens-induced uveitis.
Key words: cataract; cataract extraction; lens-induced uveitis; lens injury; pars plana vitrectomy
