| 1 | Changes in corneal curvature and aberrations after cataract surgery显示文摘Background:Surgically induced astigmatism(SIA)and corneal high-order aberrations(HOAs)are the two main causes of poor visual quality after cataract surgery.Changes in the parameters of corneal HOAs after cataract surgery and their effects on and relationships with changes in corneal curvature have not yet been reported.This study aimed to explore changes in anterior,posterior and total corneal curvature,astigmatism and HOAs after microincision cataract surgery.Methods:Sixty-one age-related cataract patients(61 eyes)were included in this prospective study.The total,anterior and posterior corneal astigmatism and corneal HOAs were analyzed by anterior segment optical coherence tomography(AS-OCT)and iTrace before,one day,one week and three months after 2.2 mm temporal microincision coaxial phacoemulsification to evaluate the changes in anterior,posterior and total corneal curvature,astigmatism and corneal HOAs.Results:The mean J0 and J45 values of anterior,posterior and total corneal curvature obtained by ASOCT showed no statistically significant difference between preoperatively and any postoperative followup.SIA occurred on the anterior,posterior and total corneal surfaces and showed no statistically significant difference at any postoperative follow-up.No significant changes in 3rd-order oblique trefoil,vertical coma or 4th-order spherical aberrations were observed after surgery except for a significant increase in horizontal coma at postoperative day 1(POD1).Conclusions:There were no significant changes in corneal curvature after 2.2 mm temporal microincision coaxial phacoemulsification,and the corneal HOAs were not changed significantly except for the increase in horizontal coma at POD1,which may be one of the main reasons of poor visual quality at POD1 in some cataract patients who have good uncorrected or corrected distance vision. | Ye Dai Xiaoting Ruan Wei Wang Xiaoyun Chen Guangming Jin Lanhua Wang Xiaoxun Gu Bo Qu Jianping Liu Xuhua Tan Enen Zhang Jun Fu Lixia Luo Zhenzhen Liu Yizhi Liu | 2022 | Annals of Eye Science2022，，3： | 0 |
| 2 | A nano fiber–gel composite electrolyte with high Li^(+) transference number for application in quasi-solid batteries显示文摘As their Liþtransference number(tLiþ),ionic conductivity,and safety are all high,polymer electrolytes play a vital role in overcoming uncontrollable lithium dendrites and low energy density in Li metal batteries(LMBs).We therefore synthesized a three-dimensional(3D)semi-interpenetrating network-based single-ion-conducting fiber–gel composite polymer electrolyte(FGCPE)via an electrospinning,initiation,and in situ polymerization method.The FGCPE provides high ionic conductivity(1.36 mS cm^(-1)),high t_(Li+)(0.92),and a high electrochemical stability window(up to 4.84 V).More importantly,the aromatic heterocyclic structure of the biphenyl in the nanofiber membrane promotes the carbonization of the system(the limiting oxygen index value of the nanofiber membrane reaches 41%),giving it certain flame-retardant properties and solving the source-material safety issue.Due to the in situ method,the observable physical interface between electrodes and electrolytes is virtually eliminated,yielding a compact whole that facilitates rapid kinetic reactions in the cell.More excitingly,the LFP/FGCPE/Li cell displays outstanding cycling stability,with a capacity retention of 91.6%for 500 cycles even at 10C.We also test the FGCPE in high-voltage NMC532/FGCPE/Li cells and pouch cells.This newly designed FGCPE exhibits superior potential and feasibility for promoting the development of LMBs with high energy density and safety. | Lin Wang Shugang Xu Zhe Wang Enen Yang Wanyuan Jiang Shouhai Zhang Xigao Jian Fangyuan Hu | 2023 | eScience2023，3，2： | 0 |
