Cyclotorsion of the eye is a factor that affects the accuracy of astigmatic correction after small incision lenticule extraction(SMILE), potentially leading to unexpected outcomes such as astigmatic undercorrection and an increase in higher-order aberrations. One possible explanation for these issues is the lack of active rotational tracking software in the VisuMax femtosecond laser system. Accurately measuring ocular cyclotorsion can effectively guide the design of the surgery and improve the postoperative visual quality. Several methods have been developed to measure and compensate for cyclotorsion during SMILE. This article reviews the characteristics of cyclotorsion in refractive surgery, the methods of cyclotorsion compensation, and the impact of cyclotorsion compensation on the outcomes of SMILE.

With the continuous development of refractive surgery, people's focus has gradually shifted from improving vision to improving visual quality, and personalized laser-assisted in situ keratomileusis(LASIK)surgery has gradually become people's preferred choice. Femtosecond laser-assisted keratoplasty provides better advantages for personalized LASIK surgery. This article mainly introduces the commonly used femtosecond laser-assisted personalized LASIK surgery(FS-LASIK)in recent years, such as wavefront-optimized, wavefront-guided, topography-guided, Q value-guided(aspheric cutting), personalized surgery “Wavelight Plus” and personalized surgery when correcting patients with age-related inadequate accommodation. This article focuses on analyzing the advantages and disadvantages of different personalized FS-LASIK, as well as the research progress in recent years, and also focuses on comparing the differences between different personalized surgeries.

AIM: To evaluate the safety and efficacy of allogeneic intrastromal lenticule implantation combined with corneal collagen cross-linking(CXL)in patients with moderate to advanced keratoconus.METHODS: A retrospective case series analysis was conducted. A total of 19 patients(20 eyes)with moderate to advanced keratoconus who underwent combined allogeneic intrastromal lenticule implantation and CXL at the Jinan Mingshui Eye Hospital from June 2021 to December 2023 were included. The uncorrected distance visual acuity(UCVA), thinnest corneal thickness, central corneal epithelial thickness, anterior corneal flat keratometry(Kf), steep keratometry(Ks), and mean keratometry(Km), as well as the first applanation time(A1T), the first applanation length(A1L), the velocity during the first applanation moment(VIN), the second applanation time(A2T), the second applanation length(A2L), the velocity during the second applanation moment(VOUT), highest concavity time(HCT), highest concavity radius(HCR), peak distance(PD), deformation amplitude(DA), stiffness parameter at first applanation(SP-A1), integrated radius(IR), central corneal thickness(CCT), intraocular pressure(IOP), corneal thickness-corrected IOP, biomechanically intraocular pressure IOP(bIOP), and corneal thickness variation rate(ARTH)were compared between the two groups before surgery and at 1 wk, 1, 3 and 6 mo after surgery.RESULTS: All patients successfully completed the surgery without any intraoperative complications. No significant differences were observed between pre-operative and post-operative measurements for UCVA or the corneal biomechanical parameters, including A1L, A2L, PD, A1T, A2T, VIN, VOUT, DA, IOP, and bIOP(all P>0.05). Significant differences were found between pre-operative and post-operative values for corneal thinnest point thickness, central corneal epithelial thickness, Kf, Ks, Km, and the corneal biomechanical parameters, including HCT, HCR, SP-A1, ARTH, IR, and CCT(all P<0.05). The anterior corneal curvature demonstrated an initial increase followed by a decrease post-operatively. Furthermore, significant differences were observed between pre-operative and post-operative values for HCT, HCR, SP-A1, ARTH, IR, and CCT(all P<0.005).CONCLUSION: Allogenic intrastromal lenticule implantation combined with corneal collagen cross-linking demonstrates favorable safety and stability in treating moderate-to-advanced keratoconus. This combined procedure effectively increases corneal thickness and rigidity, resulting in corneas that are more resistant to deformation postoperatively.

The defocus curve, which quantifies visual performance under various defocus states to accurately evaluate the eye's ability to achieve clear vision across a continuous range of distances, is a vital tool for assessing visual quality. With the aging population and improved quality of life driving a significant increase in the demand for presbyopia correction, the application of the defocus curve has continually expanded in ophthalmic clinical practice, particularly in the perioperative period of presbyopia-correcting corneal refractive surgery and refractive cataract surgery, where it aids in personalized surgical planning and proves valuable for patient education and postoperative visual quality assessment. This article systematically reviews the examination methodology, influencing factors, analytical approaches, and recent clinical advancements of defocus curves, focusing on the potential impact of variables such as pupil diameter, contrast sensitivity, and chart selection on results; it further discusses current limitations including lack of standardization and insufficient assessment of dynamic visual performance, and proposes future research directions based on the latest literature. The aim is to provide valuable insights for researchers and clinicians, promote the standardized and normative application of defocus curves, and ultimately enhance the overall efficacy of presbyopia correction and patients' quality of visual life.

Metastasis serves as an indicator of malignancy and is a biological characteristic of carcinomas. Epithelial-mesenchymal transition (EMT) plays a key role in the promotion of tumor invasion and metastasis and in the enhancement of tumor cell aggressiveness. Prostaglandin E synthase 3 (p23) is a cochaperone for heat shock protein 90 (HSP90). Our previous study showed that p23 is an HSP90-independent transcription factor in cancer-associated inflammation. The effect and mechanism of action of p23 on lung cancer metastasis are tested in this study. By utilizing cell models in vitro and mouse tail vein metastasis models in vivo, the results provide solid evidence that p23 is critical for promoting lung cancer metastases by regulating downstream CXCL1 expression. Rather than acting independently, p23 forms a complex with RNA-binding motif protein 14 (RBM14) to facilitate EMT progression in lung cancer. Therefore, our study provides evidence for the potential role of the RBM14-p23-CXCL1-EMT axis in the metastasis of lung cancer.

Childhood primary renal tubular diseases are chronic kidney diseases characterized by impaired renal tubular reabsorption. Primary renal tubular disease has diverse clinical manifestations and lacks of specificity. Laboratory tests are limited，making it prone to missed diagnosis and misdiagnosis. Based on the current knowledge of renal tubular diseases，authors propose early warning signals of renal tubular diseases such as family history of primary tubular diseases，unexplained polyhydramnios during pregnancy，polydipsia，polyuria，delayed growth and development or rickets，decreased muscle strength and tone，unexplained electrolyte disturbance，hyperuricemia，acid-base disturbance，positive urine sugar test，renal tubular proteinuria，urinary imaging examination suggesting kidney stones，calcium deposition，renal cysts and early onset of eye，ear，joint and neuron injury.Meanwhile，some universal management strategies for primary renal tubular disease are proposed，emphasizing the importance of multidisciplinary collaboration，genetic testing and individualized intervention to improve the long-term prognosis of childhood primary renal tubular diseases.
