“…In this study, the Lambda measurement was a more reliable predictor in moderate cataracts than in advanced cataracts. This finding is supported by previous studies that found that though retinometers were reliable in predicting postoperative BCVA in partially opaque lenses, they were not nearly as reliable in more opaque cataract lenses (16,20,21). It seems as though despite the excellent penetration of the media opacity using interferometric techniques (22), the prediction becomes less accurate in eyes with dense cataracts (23,24).…”

“…In this study, there was a moderate positive correlation between Lambda estimated VA potential and postoperative BCVA and it was shown to be a moderate predictor of postoperative BCVA with a tendency towards underestimation. The tendency of retinometers to underestimate postoperative BCVA has been reported previously (16,19). In this study, the Lambda measurement was a more reliable predictor in moderate cataracts than in advanced cataracts.…”

“…A paucity of data exists regarding the reliability of the Lambda potential VA measurements in preoperative cataract subjects. Approximately 2 decades ago, Tharp et al (15) reported that an earlier version of the instrument was not accurate in predicting final VA, and a more recent report found that Lambda underestimates potential VA, especially in cataracts with more severe opacifications (16).…”

“…Previous studies have investigated the prognostic relevance of interference VA in cataract patients without [12][13][14][15] and with concomitant ocular disease [16][17][18][19][20][21][22] and in patients suffering from epiretinal gliosis [23][24][25]. Analyses in patients undergoing penetrating keratoplasty were performed using laser interferometer [26][27][28] and potential acuity meter [28,29].…”

Purpose To analyze the preoperative predictive value of retinometer visual acuity (VA) in eyes following Descemet membrane endothelial keratoplasty (DMEK). Methods Patients undergoing DMEK between August 2011 and July 2020 were included. Preoperative interference visual acuity was assessed using Heine Lambda 100 Retinometer. Depending on the presence or absence of concomitant ocular disease, the Retinometer was evaluated for its ability to preoperatively predict best-corrected visual acuity (BCVA) six months after surgery using correlation, simple and multiple linear regression, contingency analyses, and receiver operating characteristic (ROC) analysis. Preoperative corneal backscatter was correlated with Retinometer prediction accuracy. Results A total of 198 eyes were included in the analysis. There was a significant correlation between Retinometer VA and postoperative BCVA (r = 0.647, P < 0.001). Regardless of the presence or absence of concomitant ocular disease and the surgery procedure (DMEK & triple DMEK), Retinometer VA was the most significant predictor of postoperative BCVA (P < 0.001). ROC analysis revealed reliable diagnostic performance of the Retinometer (AUC = 0.829, P < 0.001). A Retinometer VA ≥ 0.5 accurately predicted a postoperative BCVA ≥ 0.5 in 91% of cases. No association was found between corneal backscatter and prediction accuracy (P = 0.566). Conclusions Retinometer VA can be used for preoperative prediction of postoperative BCVA in DMEK and triple DMEK patients, independent of increased backscatter values and the presence or absence of concomitant ocular disease. By using this simple but effective tool, indication for DMEK can be facilitated and postoperative outcomes can be realistically predicted preoperatively.

Introduction: Cognitive-motor training has been shown to prevent and treat cognitive decline; however, findings on its effects on postural control are not consistent. The objective of this study was to compare the effects of two multicomponent cognitive-motor training programs on postural control in independent and autonomous community-dwelling older adults. Methods: This was a randomized and controlled longitudinal single-blind clinical trial with two parallel groups of independent and autonomous community-dwelling adults, 60 years of age or older. The study was performed in the University of São Paulo. The blocks were distributed in two groups through a random process (4: 4) with blocks of 8 participants. The generated numbers were placed in opaque sealed envelopes that were opened by the physical therapist who applied the interventions. The multicomponent group (MT) underwent multicomponent training with task-oriented exercise. The multicomponent plus group (MT+) underwent the same training as the MT with the addition of a cognitive overload (memorization, arithmetic calculation and Stroop task). All participants completed fourteen 50-minute sessions, which were held twice weekly over seven weeks. The primary measurement was postural control, evaluated using the Mini-BESTest before and after the intervention and 30 days after the training program was completed. The study was registered in the Brazilian Clinical Trials Registry under study number RBR-99xnc6. Results: Between September 2017 and December 2018, 32 participants participated in the study. In total, three participants gave up. Twenty-nine participants were allocated in the MT (n = 14) or MT + (n = 15). There was a time effect and Total Mini-BESTest score (F (2; 54) = 20.8; p = 0.001; observed power = 1.0. Post-intervention improvement (Tukey post-hoc test; p = 0.0001), which remained in the follow-up assessment (Tukey's post-hoc test; p = 0.0002), regardless of the group. found time effect on the anticipatory domain (F (2.54) = 6.9, p = 0.002; observed power = 1.0); sensory orientation (F (2.54) = 8.2; p = 0.001; observed power = 1.0) and dynamic gait (F (2.54) = 9.5; p = 0.001; observed power = 1.0) There was an improvement in post-intervention evaluation (Tukey's post-hoc test, p <0.05) that remained in the follow-up evaluation (Tukey's post-hoc test; p <0.05), regardless of the group. The simple task timed up and go analysis of TUG showed a time effect (F (2.54) = 4.8 p = 0.011, observed power = 0.8) and group (F (1.27) = 5.2 p = 0.03, observed power = 0.6). Tukey's post-hoc test on the simple task TUG showed a difference between groups p = 0.03 and time effect p = 0.008 (baseline vs follow-up) regardless of the group. TUG analysis in cognitive task showed time effect (F (2.54) = 3.9; p = 0.026; observed power = 0.7). Tukey's post-hoc dual-task TUG test showed time effect p = 0.03 (baseline vs follow-up) regardless of group. Conclusion: Multicomponent training provided an improvement in postural control in independent elderly, and the addition of ...
