Incidence of cystoid macular edema after different cataract operations.

With the development of new cataract surgical techniques, the question has arisen of whether the incidence of cystoid macular edema has actually increased, decreased or remained unchanged. A control study to determine the incidence of persistent cystoid edema following extracapsular cataract extraction and artificial lens implantation versus a similar age-group is being done in Miami using the traditional intracapsular cataract technique. The incidence of cystoid edema among patients submitted for phacoemulsification with or without lens implantation are also discussed.
