Patient’S Satisfaction, Visual Quality, And Photic Phenomena In The Long Term With A Novel Trifocal Intraocular Lens

To assess the visual quality and photic phenomena three and twelve months after the implantation of a widespread diffractive design of intraocular lens (IOL) manufactured with an evolved material.

Clínica Rementería, Madrid, Spain.

This restrospective study included 34 patients with the Clareon® PanOptix^TM IOL. Three and twelve months after the surgery, binocular contrast sensitiviy (CS) under photopic conditions, halo perception with halometer, questions related to the presence of dysphotopsias and the need of addition correction were performed. Patients also fulfilled the Catquest 9-SF questionnaire. 

The study included 34 patients. CS results showed no statistically significant differences between both follow visits (p>0.05 for all spatial frequencies). Discrimination index related to halo perception was stable from the 3 to the 12 months visit (p=0.41). The subjective perception of photic phenomena showed no significant changes between both visits. The proportion of patients that never needed additional spectacles for far and intermediate distances increased a 7% one year after the surgery. The proportion of patients that were very satisfied with their vision increased 7% one year after the surgery and results of overall difficulties in daily activities remained stable.

The results suggest that the diffractive IOL under study provide high rates of patient’s satisfaction. In addition, the stable CS and photic phenomena results also implies that the novel material preserves the optical performance in the long term.
