Violet light-transmitting intraocular lens increases choroidal thickness: 1-year prospective, randomised controlled trial.

ABSTRACT:

Aims

To compare the changes in ocular parameters after implantation of two types of intraocular lenses (IOLs) following cataract surgery. One IOL transmits violet light (VL), and the other does not.

Methods

A total of 402 patients were randomly assigned to receive either a VL-non-transmitting IOL or a VL-transmitting IOL. Ocular parameters were measured preoperatively and postoperatively, and participants completed a lifestyle questionnaire. The choroidal thickness (CT) was measured using the PLEX Elite 9000 (Carl Zeiss Meditec). The associations between changes in CT and age, sex, type of IOL, preoperative CT, time spent outdoors, time spent using a smartphone or tablet and time spent reading were examined using stepwise multiple regression analysis (SPSS V.28.0 for Windows
