ABSTRACT
BACKGROUND: Capsular contracture is the most common complication following breast implant surgery, and the implant shell characteristics are important in preventing this complication. OBJECTIVES: The aim of this study was to evaluate the capsular contracture rate for SmoothSilk Motiva implants (Establishment Labs Holdings Inc., New York, NY) in females who underwent primary and revisional breast augmentation over a 3-year period. METHODS: A total of 1324 cases that took place from 2017 to 2020 were retrospectively analyzed, with 1027 being primary surgeries and 297 being revisional surgeries. RESULTS: In the 1324 cases of augmentation mammoplasty with SmoothSilk Motiva implants, the overall capsular contracture rate was 1.8% (n = 24). The capsular contracture rate in the 1027 primary surgery cases was 1.07% (n = 11), and the capsular contracture rate in the 297 revisional surgery cases was significantly different at 4.39% (n = 13, P = .0001). More specifically, the capsular contracture rate in 182 revisional surgery for cases without capsular contracture was 1.12% (n = 2), and it showed no statistically significant difference from the rate in primary surgery cases (P = .965). However, the rate in 115 revisional surgery for cases with capsular contracture was 9.57% (n = 11), and it showed a statistically significant difference from the rate in primary surgery cases (P = .000) and the rate in revisional surgery for cases without capsular contracture (P = .001). CONCLUSIONS: Augmentation mammoplasty with SmoothSilk Motiva implants demonstrated a lower rate of capsular contracture than traditional smooth or textured implants. Revisional surgery for cases without capsular contracture showed a similar rate of capsular contracture to primary surgery cases, but the rates were higher in revisional surgery for cases with capsular contracture.

PURPOSE: To investigate visual field (VF) progression rates in glaucomatous eyes with myopic optic disc appearance, refractive error, and progressive VF changes and to compare the rates with those of a nonmyopic group. PATIENTS AND METHODS: Data on 158 eyes from 131 patients with open-angle glaucoma who had progressive VF deterioration during follow-up were retrospectively analyzed. The myopic and nonmyopic groups were compared in terms of rates of change of mean thresholds in global and regional areas using central 10 degrees, peripheral 10 to 24 degrees, and glaucoma hemifield test maps by using a linear-mixed model and controlling for confounding covariates. Clinical factors associated with rapid VF progression at global and regional VF areas were investigated in each group. RESULTS: The 2 groups did not significantly differ in the mean global VF progression rate (-0.36 vs. -0.35 dB/y, respectively; P=0.951). Likewise, both groups showed similar VF progression rates at all regional clusters (P>0.05). No significant association was found between the rate of VF change and clinical factors in the myopic group. The mean follow-up intraocular pressure was significantly associated with VF progression rates in the nonmyopic group (P<0.05). CONCLUSIONS: Open-angle glaucoma eyes with myopic optic disc appearance experiencing progressive VF changes showed similar VF progression rates globally and regionally when compared with nonmyopic eyes after controlling for clinical factors related to VF progression. None of the clinical factors in the myopic group were significantly associated with VF progression rate, whereas the mean follow-up intraocular pressure was in the nonmyopic group.
