Full description
The present study aims to validate the Catquest-9SF questionnaire in the Greek population. The Catquest-9SF is a questionnaire for assessing the quality of vision of patients with cataract. It consists of 9 questions, two of which concern the subjective assessment of the patient's vision and the other seven the patient's ability to perform various daily activities.
The Catquest-9SF questionnaire were translated into the Greek language by a translation team consisting of five members: one translation coordinator, two professional native English-speaking translators, one professional native Greek-speaking translator and one native Greek ophthalmologist fluent in English.
Patients participating in the study are asked to complete a questionnaire in Greek before and after cataract surgery. Upon completion of the data collection, data are processed and analyzed through Rasch analysis to determine whether the questionnaire can be used in clinical practice in this translated version.
The following clinical parameters are evaluated: age, gender, preoperative and postoperative monocular distance uncorrected visual acuity (UVA), distance best spectacle-corrected visual acuity (BSCVA) of the eye for cataract surgery, binocular distance UVA and BSCVA, refraction, spherical equivalent (SE), and intraocular pressure.
