“…However, the level of variability in this distribution of illumination conditions also varied significantly among individuals, with a range of variation of the time dedicated to activities under photopic, mesopic, and scotopic conditions of 5 to 87%, 6 to 67%, and 4 to 65%, respectively. This factor is especially critical considering that eyes implanted with multifocal IOLs had a photopic pupil size of 3.5 mm or less and a mesopic pupil size of 5 mm or less [ 33 ], and this change can be very relevant clinically when they are implanted with IOL models showing some type of pupillary dependence or leading to a decrease in contrast sensitivity especially in mesopic conditions [ 34 , 35 ]. Therefore, a characterization of the illumination conditions, and not only of distance, should be considered as an additional critical factor when selecting the specific type of PC IOL to implant in each case.…”

Purpose. To evaluate and report the visual habits and requirements of a sample of presbyopic patients using an advanced sensor. Methods. Transversal study collecting clinical data from 40 presbyopes candidates for presbyopia-correction intraocular lens (IOL) implantation with mean age of 61.0 years (43–80 years). A complete ophthalmological examination was performed in all patients including visual, refractive, an ocular biometric analysis. Furthermore, patients were instructed about the use of the Vivior Monitor system (Vivior AG, Zürich, Switzerland), which consists of a series of sensors attached to the rim of the patient’s glasses that capture information about the visual behavior of the patient. This device was worn for a period of 36 hours or more. The data collected were transferred to a database and analyzed. Results. Mean percentages of time dedicated to distance, intermediate, and near vision were 27.25 ± 11.93% (5–65%), 30.23 ± 9.36% (12–50%), and 42.53 ± 14.96% (13–78%), respectively. Mean percentages of time performing activities under photopic, mesopic, and scotopic conditions were 37.08 ± 23.20% (5–87%), 33.65 ± 13.84% (6–67%), and 29.28 ± 17.03% (4–65%). The percentage of time with digital screens ranged from 2% to 48%. Age was significantly correlated with the percentage of time dedicated to distance vision (r = 0.317, p = 0.047 ) and to activities performed under photopic conditions (r = −0.344, p = 0.030 ). Conclusions. Distance and illumination conditions used to perform different daily life visual activities vary significantly among presbyopes, with a trend to the dedication of more time to intermediate and near visual activities performed under photopic and mesopic conditions. Data interpretation should be done with care until a proper validation of the device used.

Purpose To assess the efficacy and safety of various intraocular lenses (IOLs), including standard monofocal, bifocal, trifocal, extended depth of focus (EDOF), and enhanced monofocal IOLs, post-cataract surgery through a network meta-analysis. Methods A systematic search of PubMed, Cochrane Library, and Web of Science was conducted to identify relevant studies from the past 5 years. Parameters such as binocular visual acuities, spectacle independence, contrast sensitivity (CS), and optical quality were used to evaluate efficacy and safety. Data from the selected studies were analyzed using Review Manager 5.4 and STATA 17.0 software. Results Twenty-eight Randomized Controlled Trials (RCTs) comprising 2465 subjects were included. Trifocal IOLs exhibited superior uncorrected near visual acuity (UNVA) compared to monofocal IOLs (MD: -0.35; 95% CI: -0.48, -0.22). Both trifocal (AcrySof IQ PanOptix IOLs group MD: -0.13; 95% CI: -0.21, -0.06) and EDOF IOLs (MD: -0.13; 95% CI: -0.17, -0.09) showed better uncorrected intermediate visual acuity (UIVA) than monofocal IOLs. Trifocal IOLs ranked highest in spectacle independence at various distances (AT LISAtri 839MP group: SUCRA 97.5% for distance, 80.7% for intermediate; AcrySof IQ PanOptix group: SUCRA 83.0% for near). Conclusions For cataract patients who want to treat presbyopia, trifocal IOLs demonstrated better visual acuity and spectacle independence at near distances. Different types of trifocal IOL characteristics differ. EDOF and enhanced monofocal IOLs have improved visual quality at intermediate distances.Therefore, It is very important to select the appropriate IOLs based on the lens characteristics and patient needs.
