With the widespread application of functional intraocular lense (IOL), the accuracy of refractive prediction in cataract patients is increasingly important. Although IOL power calculation formulas have been innovated continuously in recent years, there are still challenges in predicting refractive powerin cataract patients with abnormal anatomical parameters, ocular comorbidities, or a history of ocular surgery. Based on the the characteristics of biological parameters and medical history to selcet appropriate IOL power formula, it is an important guarantee for accurate refractive prediction in cataract patients.
AIM： To explore the clinical treatment of peripheral necrotizing keratitis after femtosecond laser-assisted??in situ?keratomileusis (FS-LASIK). METHODS：Retrospective case-control study. A total of 18,448 cases of FS-LASIK were collected in our hospital from 2022-06/2023-05. 22 cases and 39 eyes of patients with peripheral necrotizing keratitis were observed. The scope of peripheral corneal necrosis were examined under a slit lamp microscope and treated accordingly. And 30 cases of patients who were operated on the same day were randomly selected as the control group. Observe the changes in naked eye visual acuity, diopters and intraocular pressure between the two groups after cure. RESULTS：Among the 18,448 cases, 22 patients and 39 eyes with peripheral necrotizing keratitis were found, with an incidence rate of 1.2‰, including 4 males and 18 females, aged 31 ± 5.0 years old. Topical tobramycin and dexamethasone eye drops were administered once an hour and in descending order every other day. The patient's pain, foreign body sensation, and tearing symptoms were significantly relieved. Most of the peripheral corneal necrosis lesions improved in 1 week, and gradually healed to form interlaminar clouds in 2 weeks. After treatment, the naked eye visual acuity, intraocular pressure, and diopters of the PNK group showed no significant changes compared with those of the control group. No glucocorticoid-induced intraocular hypertension occurred. CONCLUSION：Topical tobramycin and dexamethasone eye drops have a good therapeutic effect on peripheral necrotizing keratitis. The necrotic area forms scars after healing. The PNK case in this article is limited to the periphery and has no significant impact on naked eye vision, intraocular pressure, and diopters.

Abstract: Objective To retrieve and analyze the clinical trials of Chinese medicine against dry eye disease(Dry eye disease，DED) included in the China Clinical Trial Registry (ChiCTR), and to understand their distribution characteristics and development trends. Methods A computerized search was performed on the clinical trials related to the prevention and treatment of dry eye in TCM included in ChiCTR from the establishment of the database to January 27, 2024, data were extracted and entered into Excel 365 for de-emphasis, and the included data were statistically analysed using the SPSS 26.0 software, and the corresponding charts were plotted to summarize the characteristics of the clinical trials. Results A total of 29 clinical trials were included, of which 24 were pre-registered. The registered research projects involved 8 provincial administrative regions and 21 clinical trial organizations in Shanghai, Beijing, Guangdong, Hunan, Zhejiang, Fujian, Shenzhen, and Hubei provinces, among which the Shanghai Institute of Acupuncture and Meridian Research (7 projects, 24.14%) registered the largest number of projects. The sources of funding were mainly 13 local finance (43.33%), self-funding (26.67%), university research funding (10.00%), pharmaceutical company funding (10.00%), hospital funding (6.67%), and national financial support (3.33%). The types of studies were mostly intervention studies (24, 87.76%), and the study design was most frequently randomized parallel controlled studies (25, 86.20%). Interventions included acupuncture, classic Chinese herbal formulas/hospital-made formulas, and proprietary Chinese medicines, and outcome indicators included primary, secondary, side effect, and additional indicators. Conclusion The rise in the number of clinically registered trials of Chinese medicine against dry eye in China tends to stabilize, the distribution of registration areas is not balanced, and the filling of clinical trial data is incomplete and not standardized, and the follow-up should strengthen the training of investigators about clinical trial registration and improve the awareness of clinical trial registration among investigators.
Abstract Aim: The objective of this study was to investigate the prognosis of massive vitreous hemorrhage (VH) secondary to polypoidal choroidal vasculopathy (PCV) after vitrectomy. Methods: Forty-nine eyes in 48 patients with PCV and breakthrough VH who underwent 23-gauge pars plana vitrectomy between January 2015 and December 2020 were enrolled. The main outcome parameters were best-corrected visual acuity, postoperative adverse events, and reoperation. Results: The average follow-up time was 20.0±15.82 months. The average preoperative best-corrected visual acuity (BCVA) was 2.12±0.65 logarithm of the minimum angle of resolution (logMAR), the BCVA at six months was 1.65±0.64 logMAR, and the six-month follow-up BCVA was 1.67±0.76 logMAR. Compared to the average preoperative BCVA, the six-months and last follow-up BCVA after vitrectomy improved (P<0.05). Postoperative complications were observed in 10 eyes (20.4%), including recurrent retinal detachment, recurrent vitreous hemorrhage, macular hole, hyphema and lens dislocation. Fourteen eyes (28.6%) underwent cataract surgery procedure an average of 10.16±5.14 months after vitrectomy. BCVA one week and three months after cataract surgery improved compared to BCVA before cataract surgery (P<0.05). Conclusions: Although the prognosis of vitrectomy varies greatly, cataract surgery could be considered to improve BCVA if polypoidal lesions are inactive six months after vitrectomy.

Objective: To investigate the effects of a compound Lycium barbarum fumigation formulation administered through ultrasonic nebulization on corneal status and tear film quality in a rat model of evaporative dry eye, providing experimental evidence for the clinical use of the compound Lycium barbarum fumigation formulation. Methods: Forty clean-grade male Sprague-Dawley rats were randomly divided into four groups: control group, model group, sodium hyaluronate eye drops group, and traditional Chinese medicine (TCM) nebulization group. Except for the control group, the remaining three groups were induced to develop the evaporative dry eye model using a mechanical method of blocking the meibomian glands. After successful modeling, the model group received no treatment, the sodium hyaluronate eye drops group received sodium hyaluronate eye drops three times daily (1 drop each time), and the TCM nebulization group received the compound Lycium barbarum fumigation formulation via nebulization twice daily for 20 minutes each time. Tear film break-up time (BUT), corneal injury score, tear pH value, and other indicators were observed before intervention, after 2 days, 1 week, and 2 weeks of intervention. Results: Tear film break-up time: After 2 days of TCM nebulization, the tear film break-up time was significantly prolonged in the TCM nebulization group and the sodium hyaluronate eye drops group compared to the model group (P<0.01). After 1 and 2 weeks, the tear film break-up time in the TCM nebulization group further increased compared to the model group and the sodium hyaluronate eye drops group (P<0.01). The effect of TCM nebulization treatment was most significant after 2 days, with BUT approaching the level of the control group. Corneal injury score: After 2 days of TCM nebulization, the corneal injury score significantly decreased, while there was no significant change in the sodium hyaluronate eye drops group. After 1 and 2 weeks, both the TCM nebulization group and the sodium hyaluronate eye drops group showed a significant reduction in corneal injury score (P<0.01), with the TCM nebulization group demonstrating a more significant improvement. Tear pH value: After 2 days of TCM nebulization, there was a significant decrease in tear pH value, while there was no significant change in the sodium hyaluronate eye drops group. After 1 and 2 weeks, the tear pH value continued to decrease in the TCM nebulization group, while there was no significant change in the sodium hyaluronate eye drops group. The effect of TCM nebulization treatment was most significant after 2 weeks, with a more significant decrease in tear pH value. Conclusion: TCM nebulization treatment with the compound Lycium barbarum fumigation formulation shows significant effects in alleviating ocular surface dysfunction, improving corneal injury scores, and reducing tear pH values, which are more significant compared to the sodium hyaluronate eye drops group.
Background Research innovations on disease screening, diagnosis, and management in ophthalmology have been boosted by deep learning (DL) in the last decade. To assess historical research trends and current advances, we conducted an artificial intelligence (AI)–human hybrid analysis of publications on DL in ophthalmology. Methods All DL-related articles in ophthalmology published between 2012 and 2022 from Web of Science were included. 500 high-impact articles annotated with key research information were used to fine-tune an LLM for reviewing medical literature and extracting information. After verifying the LLM's accuracy in extracting diseases and imaging modalities, we analyzed trend of DL in ophthalmology using 2535 articles. Results Researchers using LLM were 70% (p = 0.0001) faster than those who did not, while achieving comparable accuracy (97% versus 98%, p = 0.7681). The field has grown 116% annually, paralleling trends of the broader DL domain. The publications focused heavily on diabetic retinopathy (p = 0.0003), glaucoma (p = 0.0011), and age-related macular diseases (p = 0.0001) using retinal fundus photographs (FP, p = 0.0015) and optical coherence tomography (OCT, p = 0.0001). DL studies utilizing multimodal images have been growing, with FP and OCT combined being the most frequent. Furthermore, 43 publicly available ocular image datasets were summarized. Conclusion This study has characterized the landscape of publications on DL in ophthalmology, by identifying the trends and breakthroughs among research topics and the fast-growing areas. This study provides an efficient framework for combined AI–human analysis to comprehensively assess the current status and future trends in the field.
