| 1 | Differences in energy and corneal endothelium between femtosecond laser-assisted and conventional cataract surgeries:prospective,intraindividual,randomized controlled trial显示文摘AIM: To compare intraoperative phacoemulsification parameters and its effect on the corneal endothelium of eyes undergoing femtosecond laser-assisted cataract surgery(FLACS) versus conventional phacoemulsification(CP) cataract surgery.METHODS: Two hundred eyes from one hundred patients were included in a prospective, non-blinded, randomized, controlled, intraindividual clinical study. One hundred eyes underwent FLACS while their one hundred fellow eyes underwent CP. All surgeries were performed using the Victus? femtosecond laser platform and Infinity? Vision System phacoemulsification machine. Primary outcome measure was endothelial cell density 6 mo after surgery. Secondary outcome measures included central corneal thickness(CCT), average cell area, standard deviation, coefficient of variation and hexagonality before surgery and 6 mo after surgery and endothelial cell density loss during this period were also evaluated. Intraoperative efficiency parameters [cumulative dissipated energy(CDE), total intraocular surgery time, total ultrasound time, total phacoemulsification time, total torsional energy time, total aspiration time, ultrasound energy, torsional amplitude and fluid required during surgery] were also collated. RESULTS: Data from these patients was not considered for analysis. Data from 92 patients were analysed. Postoperative endothelial cell density(cells/mm2) between groups(2211.88±392.49 CP; 2246.31±403.48 FLACS) was not statistically significant(P=0.869). Total ultrasound time, torsional energy time, CDE and fluid requirements were significantly lower the FLACS group(P<0.05). Other parameters did not show statistically significant difference between FLACS and CP.CONCLUSION: FLACS displays significant improvements in phacoemulsification parameters in comparison to CP. There are no significant differences in corneal endothelium measures between FLACS and CP. | Lucia Bascaran Txomin Alberdi Itziar Martinez-Soroa Cristina Sarasqueta Javler Mendlcute | 2018 | International Journal of Ophthalmology(English edition)2018，11，8： | 5 |

| 3 | Mass data processing of time series Landsat imagery:pixels to data products for forest monitoring显示文摘Free and open access to the Landsat archive has enabled the implementation of national and global terrestrial monitoring projects.Herein,we summarize a project characterizing the change history of Canada’s forested ecosystems with a time series of data representing 1984-2012.Using the Composite2Change approach,we applied spectral trend analysis to annual best-available-pixel(BAP)surface reflectance image composites produced from Landsat TM and ETM+imagery.A total of 73,544 images were used to produce 29 annual image composites,generating∼400 TB of interim data products and resulting in∼25 TB of annual gap-free reflectance composites and change products.On average,10%of pixels in the annual BAP composites were missing data,with 86%of pixels having data gaps in two consecutive years or fewer.Change detection overall accuracy was 89%.Change attribution overall accuracy was 92%,with higher accuracy for standreplacing wildfire and harvest.Changes were assigned to the correct year with an accuracy of 89%.Outcomes of this project provide baseline information and nationally consistent data source to quantify and characterize changes in forested ecosystems.The methods applied and lessons learned build confidence in the products generated and empower others to develop or refine similar satellite-based monitoring projects. | Txomin Hermosilla Michael A.Wulder Joanne C.White Nicholas C.Coops Geordie W.Hobart Lorraine B.Campbella | 2016 | International Journal of Digital Earth2016，9，11： | 1 |

| 6 | Anterior and posterior capsule densitometry levels after femtosecond laser-assisted cataract surgery显示文摘AIM: To analyze and compare five different variables over one year follow-up(1 wk, 1, 3, 6 and 12 mo): anterior capsule(AC), and posterior capsule(PC) area densitometry values, AC and PC linear densitometry values, and AC opening area reduction ratio after femtosecond laserassisted cataract surgery. METHODS: This was a prospective comparative study. Seventy-one patients underwent femtosecond laser-assisted cataract surgery on single eye between June 2014 and December 2015. A 5.0 mm diameter laser assisted anterior capsulotomy was performed on all eyes. In every postsurgery evaluation, AC opacificaction(ACO) and PC opacification(PCO) density levels were provided by Oculus Pentacam~?HR using area and linear densitometry methods. Digital images were captured with a slit-lamp Topcon photographic camera and IMAGEnet~? 5 software. The AC opening area on the digital images was measured using the Sketchandcalc area calculator and converted to reduction ratio levels.RESULTS: Using Pearson correlation coefficient(PCC), we found no correlation(r=-0.091, P=0.46) in the twelfth month assessment between the evolution of ACO area densitometry values and PCO area densitometry values considered as independent variables. We found no correlation, using PCC(r=-0.096, P=0.43) between the evolution of ACO linear densitometry values and PCO linear densitometry values, in the twelfth month visit, working both as independent variables. AC linear densitometry levels and AC area densitometry levels continued to grow strongly from sixth to twelfth months. Analysis of the values of AC opening area reduction ratio(1 wk, 1, 3, 6, 12 mo) revealed statistically significant differences between the values of successive examinations but the magnitude of the change decreased. In the final period of monitoring between six and twelve months the magnitude of change was low.CONCLUSION: Our results show strong increases of Scheimpflug ACO densitometry values from the sixth to the twelfth month while capsulorhexis area reduction ratio levels displayed a considerable decrease. We found no correlation between ACO area and linear densitometry values and PCO area and linear densitometry values, in the twelfth month examination, working as independent variables. | Txomin Alberdi Javier Mendicute Lucia Bascaran Olatz Barandika Javier Ruiz-Ederra | 2018 | International Journal of Ophthalmology(English edition)2018，11，4： | 0 |
