Article Title: A Retrospective Study: Comparative Visual Performance of Two Non-Diffractive Extended Depth-of-Focus Intraocular Lenses: TECNIS PureSee versus Clareon Vivity

doi: 10.2147/OPTH.S602008

Figure Lengend Snippet: Comparison of mean postoperative visual acuity between the Vivity and the PureSee groups at different distances. Visual acuity is presented in logMAR units. UIVA: Uncorrected intermediate Visual Acuity measured at 66cm distance; UNVA: Uncorrected Near Visual Acuity measured at 40cm distance. Error bars represent standard deviation. Asterisk (*) indicates a statistically significant difference (P < 0.05).

Article Snippet: Postoperative uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected intermediate visual acuity (UIVA), uncorrected near visual acuity (UNVA) were assessed two months after surgery using a standardized logMAR chart (ETDRS; Precision Vision, USA).

Techniques: Comparison, Standard Deviation

Article Title: Impact of Simulated Astigmatism on Visual Acuity, Stereopsis, and Reading in Young Adults

doi: 10.3390/vision9040099

Figure Lengend Snippet: Boxplot shows the lower limit, 1st quartile, median, 3rd quartile, upper limit, and outliers of the measures for the three groups (ATR—against-the-rule astigmatism; WTR—with-the-rule astigmatism; OBL—oblique astigmatism) with different powers of simulated astigmatism on distance BCVA (logMAR) compared to the baseline. BCVA—best correct visual acuity; DS—diopters sphere; DC—diopters cylinder.

Article Snippet: The inclusion criteria included: (1) no evidence of ocular disease; (2) both sexes; (3) aged between 18 and 35 years; (4) spherical refractive errors ≤ ±2.00 D without or with astigmatism ≤ −0.75 DC, and anisometropia with interocular difference in SE ≤ 0.50 diopters sphere (DS) (ocular refraction was performed under cycloplegia with the instillation of a drop of 1% tropicamide, Mydriacyl 1%, Novartis, Basel, Switzerland, and the examination was performed after 30 min); (5) best corrected visual acuity (BCVA) of 0.00 logMAR or better in both eyes; (6) normal binocular vision (orthophoria by cover/uncover test and presence of sensory fusion by the Bagolini striated lens test); (7) accommodation amplitude (AA) equal to or greater than that estimated by Hoffstetter’s formula (15 D−0.25 × age in years); (8) near point of convergence ≤ 10 cm; and (9) positive fusional vergence and negative fusional vergence with prism bar for distance and near, within normal values, distance and near, respectively, for convergence 45 Δ /40 Δ and 25 Δ /20 Δ and for divergence 14 Δ /14 Δ and 8 Δ /6 Δ [ ].
