To evaluate visual quality through defocus curves in a group of patients previously implanted with an Alcon® Vivity™ extended focus lens with best postoperative optical correction. In parallel, the patients' post-surgical subjective visual and quality of life is studied by means of questionnaires.

The study was conducted at the Ophthalmology Department of the Hospital de la Santa Creu i Sant Pau in Barcelona. All patients underwent surgery during the year 2021. Participants inclusion and exclusion criteria were established, obtaining a final sample of 36 eyes of 18 individuals (two eyes per individual). Patients between 19 and 76 years old diagnosed with cataract of any grade, in good general and ocular health, were included. Preoperative astigmatism less than 1.25 D.

 
This is an observational, cross-sectional study, in which a descriptive enumeration of selected characteristics in a group of patients with a specific treatment is performed. Independent variables: Vivity™ lens implant. 
Dependent variables: Quantitative: mesopic and photopic pupillary diameter (mm), spherical equivalent (D), distance, intermediate and near visual acuity with correction. Qualitative: Postoperative Subjective Visual Quality Questionnaire, Quality of Life Questionnaire VF-14. 

After evaluating the distribution of the values of all the variables using the Shapiro-Wilk test we see that, except for age, they all follow a normal distribution.

The subjective visual quality questionnaire revealed that the majority of patients (88.9%) reported not needing glasses for distance and intermediate distances. For night vision, as expected due to the increased pupillary diameter, this result decreases to 77.8%. For near vision, only 44.4% are able to see well without an optical aid. When patients were asked if they usually require glasses, 100% answered never for distance vision. This value drops to 88.9% for intermediate vision. For near vision, 27.8% said they always use glasses.

The Alcon® AcrySof® IQ Vivity™ lens provides good visual acuity for far and intermediate distances, with lower performance in near vision. From a subjective visual quality standpoint, all participants report a significant improvement in their vision after surgery. This is generally due to the improvement in visual acuity after surgery and independence from glasses. 
Regarding postoperative quality of life (VF-14 questionnaire) we also found high satisfaction rates.
