Aims: To assess the real-world distribution of uncorrected near visual acuity (UCNVA) in patients with highly myopic cataract ,as well as the associated refraction outcomes after cataract surgery. Methods: We conducted a cross-sectional study that included patients who had an axial length (AL) ≥26 mm in at least one eye and had undergone phacoemulsification with monofocal intraocular lens implantation. Three months or later after surgery, UCNVA was measured at a distance of 40 cm using a LogMAR ETDRS near visual acuity tumbling E chart. Other examinations carried out included non-cycloplegic autorefraction and measurement of best-corrected distance visual acuity (BCDVA). Multiple logistic regression was performed to identify the risk factors for near visual impairment (UCNVA < 20/40). Results: A total of 664 patients (664 eyes) were included in the study. The mean AL was 29.05±2.31 mm, and the postoperative spherical equivalent was -2.51±1.12D. Among these eyes, 319 eyes (48.04%) had a UCNVA of ≥ 20/40 and 518 eyes (78.01%) had a BCDVA ≥ 20/40. The risk factors for a UCNVA of less than 20/40 included postoperative astigmatism greater than 1D (-2 to -1D, odds ratio [OR]: 2.00, 95% confidence interval [CI]: 1.24 to 3.22; < -2D, OR: 4.27, 95% CI: 1.88 to 9.66), a postoperative spherical equivalent outside the range of -3.5 to -1.5D (OR: 4.17 to 19.73), and a BCDVA less than 20/40 (OR: 5.44, 95% CI: 3.14 to 9.42). Conclusions: To achieve an optimal UCNVA in patients with highly myopic cataract, it is recommended to set the target refraction between -3.5 and -1.5 D and to keep the postoperative residual astigmatism below 1D.

Objective: This study aimed to analyze the research hotspots and frontiers in orthokeratology using bibliometric methods, providing a scientific and precise reference for both new and established researchers.Methods: A bibliometric analysis was conducted on literature related to orthokeratology over the past three decades within the Web of Science Core Collection (WoSCC).  Analytical tools available in the R software environment were employed, integrating a machine learning-based bibliometric approach.Results: A total of 740 articles concerning orthokeratology research were retrieved from the WoSCC. Research on orthokeratology has shown a consistent upward trend, with an annual growth rate of 18.75%. China, Australia, and the United States are the most prolific countries in this field, with China making the largest contribution. The journals with the highest number of publications are Optometry and Vision Science (n=110), Contact Lens and Anterior Eye (n=96), and Eye & Contact Lens (n=72. Meanwhile, Pauline Cho (n=76) and Cheung SW (n=47) are the most active authors. Over the past three decades, common keywords in research literature have highlighted key areas, including corneal reshaping in pediatric populations, the prevalence and progression of myopia, contact lenses, refractive errors, and changes in axial length.Conclusions: In summary, this bibliometric analysis presents a comprehensive overview of the current state of orthokeratology research. It aids in gaining a better understanding of how  this field has developed over the past 30 years.
