Purpose
To assess the safety, efficacy and patient reported outcomes of the Q-Flex 640PM (EPS 2.0) intraocular lens after 12-months follow-up
Setting
Qvision, Ophthalmology Department, VITHAS Almería, Spain
Methods
Data was retrospectively retrieved from our historical database for 41 subjects. Visual acuities (VAs) were measured at far (4m), intermediate (66cm), and near (40cm) distances, both corrected and uncorrected. At the 3-month follow-up, the monocular visual acuity defocus curve (VADC) was measured with the best distance correction. Patient-reported outcomes were assessed at 12 months using the visual function questionnaire (VF-14), Patient Reported Spectacle Independence (SI) Questionnaire (PRSIQ), and five individual questions reporting the cumulative percentage of patients who achieved satisfaction with postoperative uncorrected vision, experienced bothersome photic phenomena, and were likely to undergo the same procedure again.
Results
Uncorrected binocular VAs were 0.01, 0.02 and 0.04 logMAR. The peak of the monocular VADC was at infinity (0 D) with a value of 0.05 logMAR, the slope of the VADC decreased up to 0.17 logMAR at -1.5D and increased again up to a second peak of 0.1 logMAR at -2.5 D. All activities of the VF-14 showed little or no difficulties except for reading small letters for which a 2.43% showed moderate difficulty. Total SI was achieved in 85.4% of patients with only 2.4% requiring spectacles for intermediate vision. More than 90.2% of patients were satisfied or very satisfied with their vision without spectacles. Only 7.3% of patients were bothersome by photic phenomena and 92.6% of patients were likely or very likely to be operated again.
Conclusions
With the use of Technology EPS 2.0, the Liberty trifocal lens demonstrated better intermediate visual acuity, without affecting the distance and near visual acuities, compared to the previously reported literature for EPS 1.0. This new version also achieved a smoother transition of visual acuity from far to near distance.
