Cataract and uveitis management by pars plana lensectomy and vitrectomy by ultrasonic fragmentation

Abstract

Cataract and uveitis occurs usually in young individuals and produces loss of vision from opacification of both the lens and vitreous. The condition does not lend itself to conventional surgery. In the experience of the authors and several other investigators, pars plana lensectomy and vitrectomy by ultrasonic fragmentation not only improves vision but apparently causes a remission of uveitis. A retrospective study of 23 eyes with cataract and uveitis undergoing pars plana lensectomy and vitrectomy by ultrasonic fragmentation (21 eyes) or vitrectomy alone (2 eyes) showed improved vision in 91.3%, no operative complications, and remission of the uveitis in 100% with observation periods of 1-11 years (average, 5 years). Pars plana lensectomy and vitrectomy appears to be the treatment of choice in cataract and chronic uveitis.
