Modern cataract surgery has completely moved beyond the traditional vision-restoring model and has fully entered a new era of refractive cataract surgery(RCS)centered on precise refractive correction. Its core objective is to provide patients with personalized visual experiences characterized by full-range, clear, and comfortable vision. Currently, although diagnostic and therapeutic technologies for RCS are rapidly evolving, there remain many bottlenecks in the precise management of the entire perioperative process that urgently need to be addressed. Preoperatively, the measurement consistency among ocular biometry devices based on different detection principles remains poor, and systematic measurement errors cannot be completely eliminated. Moreover, the individualized selection of intraocular lenses(IOLs)relies heavily on surgeons' clinical experience, lacking a standardized quantitative decision-making framework, which makes it difficult to achieve precise personalized matching. Intraoperatively, the quality of continuous curvilinear capsulorhexis is affected by multiple factors such as ocular anatomical characteristics and surgical proficiency, and its stability cannot be reliably ensured. Various intelligent surgical navigation systems are compromised by intraoperative ocular conditions, and their clinical performance fails to meet theoretical expectations. At the postoperative stage, existing IOL optical designs and materials have inherent limitations. The longterm prevention and control of posterior capsule opacification(PCO)remains a core factor restricting patients' long-term high-quality visual outcomes. This article systematically reviews the precise diagnostic and therapeutic challenges and core bottlenecks across the preoperative, intraoperative, and postoperative stages of RCS. It further explores frontier technological directions—including cross-device error compensation models, artificial intelligence-assisted decision-making, preoperative VR-based visual simulation, and the construction of intelligent surgical ecosystem platforms—to delineate targeted solutions and optimization pathways. This review aims to provide references and insights for the standardized clinical implementation, technological innovation, and future research endeavors in precision diagnosis and treatment of RCS.

Phacoemulsification represents the mainstream, efficient, and safe surgical modality for cataract treatment, and continuous technological advances have further improved the safety profile of this procedure in ordinary patients. However, patients with high myopia feature inherent anatomical abnormalities of the eyeball, leading to a fundamental incompatibility with conventional phacoemulsification protocols. Such patients face a markedly elevated risk of both anterior and posterior segment perioperative complications, posing a persistent clinical challenge in cataract surgery. Focusing on the unique ocular anatomical characteristics associated with high myopia, this review systematically summarizes the distinct traumatic effects and pathological impacts of phacoemulsification on the anterior and posterior ocular segments of affected patients. Moving beyond generalized discussions of routine cataract management, it consolidates clinical evidence specific to this special-population patients, aiming to provide refined references for perioperative risk prevention and control in cataract patients complicated with high myopia.

AIM: To evaluate the binocular visual function in high myopia patients after the implantation of implantable collamer lens(ICL)V4c.METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.

The number of interventional procedures has increased significantly due to the advantages of minor trauma, rapid recovery, and low incidence of complications. In 2018, there were approximately 24 million interventional procedures worldwide, representing a six-fold increase compared with 3.6 million procedures in 2008. From 2020 to 2021, the percentage of medical institutions with independent interventional departments in China increased from 50.49% to 63.18%. Interventional procedures inherently involve exposure to ionizing radiation, which poses a greater risk of radiation-related harm to the pediatric population due to their increased sensitivity, Consequently, the radiation dose levels experienced by children undergoing these procedures have become a growing concern, emerging as a focus of research both nationally and internationally. This article summarizes the reports published by the International Commission on Radiological Protection (ICRP), the National Council on Radiation Protection and Measurements (NCRP), and the International Atomic Energy Agency (IAEA) as well as academic articles, and reviews the dose optimization measures in the interventional procedures for pediatric patients. Regular radiation safety training for interventional radiation workers, enhancing radiation safety awareness, optimizing intraoperative techniques, and timely updating imaging equipment can effectively reduce the radiation dose received by pediatric patients. This approach helps reduce the doses to an acceptable range while still meeting interventional procedural requirements, thereby protecting the physical health of pediatric patients.

Objective To analyze the disease burden of cervical cancer in major Asian countries and globally from 1990 to 2019,which help to provide reference for the prevention and control of cervical cancer.Methods We utilized data from the(Global Burden of Disease,GBD)2019 database,and our analysis incorporated key measures such as incidence,deaths and(Disability-Adjusted Life Years,DALY)to quantitatively assess the global impact of cervical cancer.We employed the(Estimated Annual Percent Change,EAPC)to analyze the time trends in the disease burden.Results From 1990 to 2019,the global standardized incidence rate of cervical cancer decreased from 7.64/100,000 to 6.81/100,000,while the standardized death rate decreased from 4.46/100,000 to 3.40/100,000.The standardized DALYrate also decreased from 139.98/100,000 to 107.20/100,000.The annual average reductions were 0.39%,0.96%,and 0.94%,respectively(EAPC<0,P<0.05).Among major Asian countries,China's standardized incidence rate increased from 4.20/100,000 to 5.53/100,000,with an average annual growth of 1.63%(EAPC>0,P>0.05).The number of cervical cancer deaths in China increased from 26,400 to 53,400,representing a relative increase of 1.02 times.While the standardized mortality rate and standardized DALY rate for cervical cancer decreased globally and in major Asian countries,China did not exhibit a declining trend.Relevant analysis revealed no significant correlation between incidence rate and(Socio-Demographic Index,SDI)(ρ=-0.13,P=0.11).However,mortality rate showed a negative correlation with SDI(ρ=-0.74,P<0.001),and DALY also exhibited a negative correlation with SDI(ρ=-0.77,P<0.001).Conclusion The standardized incidence and death rates of cervical cancer in China have been increasing year by year,and the disease burden is on the rise.It is imperative to proactively implement scientifically effective prevention and control measures to reduce the burden of cervical cancer.

Objective To observe value of echocardiographic evaluation on infants with pulmonary atresia and intact ventricular septum(PA/IVS)for surgical decision and post operation right ventricle(RV)development.Methods Forty-six PA/IVS infants who underwent pulmonary valve(PV)annuloplasty(group A,n=25),PV annuloplasty and RV outflow tract reconstruction with/without additional systemic-to-pulmonary artery shunt(group B,n=15),and systemic-to-pulmonary artery shunt and atrial septal enlargement(group C,n=6)were retrospectively enrolled.Status of RV developments were compared among groups before operation as well as 1 and 6 months after operation.Results The presentation age in group B was younger than,while in group C was older than that in group A(both P＜0.05).Before operation,tricuspid valve(TV)annulus diameter,TV annulus Z-score and TV/mitral valve(MV)annulus ratio in groups B and C were both smaller than those in group A(all P＜0.05),whereas RV/left ventricle(LV)longitudinal diameter ratio in group B was larger and PV annulus Z-score in group C was smaller than those in group A(both P＜0.05).Meanwhile,preoperative PV annulus Z-score and RV/LV longitudinal diameter ratio in group B were both larger than those in group C(both P＜0.05).One month after operations,TV annulus diameter,TV annulus Z-score and TV/MV annulus ratio in group B and C,as well as PV annulus diameter,PV annulus Z-score and RV/LV longitudinal diameter ratio in group C were all smaller than those in group A(all P＜0.05),while PV annulus diameter,PV annulus Z-score and RV/LV longitudinal diameter ratio in group C were all smaller than those in group B(all P＜0.05).Six months after operations,no significant difference of TV annulus diameter,PV annulus diameter,PV annulus Z-score,TV/MV annulus ratio nor RV/LV longitudinal diameter ratio was found between group A and B(all P＞0.05),but the above indexes in group C were all lower than those in group A and B(all P＜0.05).Besides,no significant difference of TV annulus Z-score was found between group A and B(P＞0.05),which were lower in group C than in group A(P＜0.05).Conclusion Echocardiographic evaluation on PA/IVS infants was helpful to establishment of forward blood flow from RV to pulmonary arteries in time,hence promoting RV development.

ObjectiveTo investigate the deafness genetic mutation spectrum in nonsyndromic hearing impairment (NSHI) associated with enlarged vestibular aqueducts (EVA). MethodsFrom October, 2015 to August, 2016, 85 patients with NSHI from Hubei Yichang Special Education School were examined with temporal bone CT, and 20 deafness-related gene mutations in GJB2, GJB3, SLC26A4 and mtDNA 12S rRNA were detected with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. ResultsA total of 31 patients were found EVA with temporal bone CT. Compared with non-EVA patients, the proportion of deafness-related gene mutations was more in patients with EVA (χ² = 11.160, P = 0.001), especially for c.919-2A>G mutation of SLC26A4 (χ² = 23.870, P < 0.001). ConclusionThe deafness gene mutation spectrum is different in NSHI patients with or without EVA. It is needed to optimize genetic testing scheme for deafness for early diagnosis and intervention of NSHI associated with EVA.
