Development of a new subjective questionnaire: the Freedom from Glasses Value Scale (FGVS).

Purpose: To develop a patient self-administered questionnaire assessing the added value of complete independence from spectacles (hereafter referred to as glasses) after multifocal intraocular lens (IOL) surgery.

Methods: Exploratory interviews with five cataract patients and six presbyopic patients with AcrySof ReSTOR IOLs (Alcon Laboratories Inc) implanted in both eyes for at least 6 months were conducted. The questionnaire's conceptual framework was developed after interview analysis.
