[Incidence of cystoid macular edema following cataract extraction]

In a prospective study we research the incidence of cystoid macular edema following intracapsular cataract extraction with the Choyce-Mark-IX implantation method. The only eyes included in the study were those for which the operation had been uncomplicated. Fluorescence angiography was performed after 8 days, 6 weeks, 6 months and 1 year. The edema was graded accordingly: grades I-III. Cystoid macular edema of grade III was demonstrated in 4% after 6 weeks but not after 6 months and 1 year. After 1 year, grade II occurred in 2% and grade I in 15%, respectively. Visual acuity, however, was not impaired.
