About

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.

Full description

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.

Enrollment: 60 patients

Sex: All

Ages: 50+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Diagnosis vitreoretinal pathology (diabetic vitreous hemorrhage, macular hole, epiretinal membrane or persisting macula edema)

• Age over 50 years.

Exclusion criteria

• Pseudophakia on the non-study eye
• The need for silicone oil tamponade
• Optic atrophy.
