This study aimed to evaluate the quality of life and the satisfaction level of Brazilian and Chinese patients who underwent cataract surgery for Acysof IQ PanOptix Model TFNT00 (Alcon Laboratories, Fort Worth, TX) implantation. This retrospective study enrolled 51 patients from China and 51 patients from Brazil. At the 3-month follow-up, uncorrected distance visual acuity (UDVA) at 5m, uncorrected intermediate visual acuity (UIVA) at 60cm, and uncorrected near visual acuity (UNVA) at 40cm were evaluated; Catquest 9SF and the Near Activity Visual Questionnaire (NAVQ) were administered to the patients. The results revealed that the Brazilian patients gained better UDVA and UNVA (p<0.001), while the Chinese patients gained better UIVA (p = 0.001). With regards to the patients’ overall satisfaction with their current vision, the Brazilian patients scored higher (p = 0.002). In situations related to distant and near vision, the Brazilian patients scored higher, while in situations related to intermediate vision, the Chinese patients scored higher. No differences were found between the gender or age subgroups, but the normal axial length (AL) subgroup showed the highest level of satisfaction (p = 0.002). The patients implanted with TFNT00 IOL obtained excellent objective and subjective outcomes in both cultures. The Brazilian patients showed higher satisfaction with their distant and near vision, while the Chinese patients were more satisfied with their intermediate vision.
Objectives To assess the consistency and difference on six new instruments to IOL-master 500 through evaluating the corneal power measurements. Materials and methods 88 eyes of 88 subjects were included from Oct. 2018 to Apr. 2019 in this study. The keratometric data, magnitude of astigmatism and astigmatism axis were measured by IOLmaster 500 (Zeiss), Lenstar LS-900 (Haag-Streit), Pentacam HR (Oculus), iTrace (Tracey Technology), Verion(Alcon), Atlas 995 corneal topography (Zeiss), KR-800 auto-refractometer (Topcon), respectively. Blant-Altman analysis plots were used to evaluate the conformity of corneal curvature between these instruments, and the differences of corneal curvature were compared by one-way analysis of variance (ANOVA). Double-angle plots were used to describe the difference on astigmatism assessment. Results The mean age of all subjects was 35.86±10.27 years, and the male/female ratio was 34/54. There was no significant difference of corneal curvature in all the instruments, LoA range of each instrument compared with IOL-master 500 using Bland-Altman plots were - 0.14D~0.33D、- 0.05D~0.62D、- 1.5D~2.0D、- 0.93D~0.44D、- 0.39D~1.10D、- 0.39D~0.59D , respectively. The widest length is produced by the iTrace (-1.5D-2.0D), and the narrowest length is the Lenstar LS 900 (-0.14D-0.33D), when compared to IOL-master. Moreover, the astigmatism errors of the instruments compared with IOL-master 500 using Double-Angle plots were 0.09D×78°±0.33D, 0.08D×69°±0.40D, 0.12D×80°±0.36D, 0.09D×13°±0.41D, 0.37D×77°±0.68D, 0.14D×86°±0.39D, respectively. The maximum and minimum against-the-rule (ATR) compared to the IOL-master are Atlas 995 corneal topography and Pentacam, respectively. Conclusions These instruments showed good agreements in evaluating corneal curvature, and Pentacam is a promising choice to detect the astigmatism size and direction based on the minimum error compared with IOL-master.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
