Blue-Blocking IOLs in Combined Surgery
Although commonly used in cataract surgery, the use of the blue light-filter IOLs in vitrectomy combined with cataract surgery has not been reported yet. A prospective controlled clinical trial was designed to evaluate the effect of the blue light-filter IOL on the surgeon's ability to perform specific vitreoretinal procedures and on the patients' outcome.

|Official Title:||Blue Light-Filter IOLs in Vitrectomy Combined With Cataract Surgery: Results of a Randomized Controlled Clinical Trial.|
- intraoperative conditions for the surgeon (scaled questionnaire) and patients´ outcome
- complication rates and vitreoretinal diagnoses
|Study Start Date:||October 2004|
|Study Completion Date:||March 2006|
Procedure: combined surgery
Sixty patients were randomly assigned to receive a UV-filter IOL (transparent IOL group) or a blue light-filter IOL (yellow IOL group) combined with a vitreoretinal procedure.
Outcome measures were intraoperative conditions for the surgeon, complication rates, the functional outcome and vitreoretinal diagnoses.
