Additionally, rapid advancements in large language model (LLM) technology, including models such as GPT-4 and Gemini, have been tailored for medical specialization and evaluated on clinical scenarios with promising results. This review explores the opportunities and challenges for further advancements in these technologies.Recent findings: RETFound outperforms traditional deep learning models in specific tasks, even when only fine-tuned on small datasets. Additionally, LMMs like Med-Gemini and Medprompt GPT-4 perform better than out-of-the-box models for ophthalmology tasks. However, there is still a significant deficiency in ophthalmology-specific multimodal models. This gap is primarily due to the substantial computational resources required to train these models and the limitations of high-quality ophthalmology datasets.Summary: Overall, foundation models in ophthalmology present promising opportunities but face challenges, particularly the need for high-quality, standardized datasets for training and specialization. Although development has primarily focused on large language and vision models, the greatest opportunities lie in advancing large multimodal models, which can more closely mimic the capabilities of clinicians.","PeriodicalId":50604,"journal":{"name":"Current Opinion in Ophthalmology","volume":" ","pages":"90-98"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11620320/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142331709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average cataract surgical coverage (CSC) in the majority of countries was around 50% or lower. Additionally, in many countries, the efficient CSC (eCSC) deviates from the CSC, emphasizing the importance of attention to the quality of surgical procedures. Socioeconomic status and access to health services are key determinants in the distribution of cataract surgery. This procedure is more prevalent among older individuals, with a higher incidence among men and private insurances tend to cover a larger portion of cataract surgeries. The pandemic of COVID-19 has had a detrimental effect on cataract surgery rates in numerous countries.Summary: The rate of cataract surgery and its extent of coverage in certain countries is inadequate. The primary factor influencing the quantity and coverage of cataract surgeries is the economic status of the countries. Additionally, government support through insurance and the provision of appropriate healthcare services can contribute to an increase in cataract surgeries.","PeriodicalId":50604,"journal":{"name":"Current Opinion in Ophthalmology","volume":"36 1","pages":"10-17"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142786378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent large database studies have revealed an increased risk among young, male, and black patients. A previous history of PCME is perhaps the strongest risk factor for fellow eye involvement.Summary: PCME generally occurs around 6 weeks postoperatively and is likely a consequence of postoperative inflammation with disruption of the blood-queous and blood-retina barriers. Optical coherence tomography of the macula servers as a key diagnostic tool. There is a lack of large controlled clinical trials to guide treatment approaches. We recommend a stepwise approach for PCME that includes observation if not visually significant versus treatment with topical nonsteroidal anti-inflammatory drugs and steroids if symptomatic. Refractory cases can be treated with a periocular steroid injection, followed by intravitreal steroids if still nonresponsive.","PeriodicalId":50604,"journal":{"name":"Current Opinion in Ophthalmology","volume":" ","pages":"62-69"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142512328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Small incision sizes favour hydrophilic IOLs. Rotational stability of hydrophobic and hydrophilic IOLs were comparable in recent studies. Visual outcomes are affected by chromatic aberrations, dysphotopsia, lens opacifications and PCO. Hydrophilic IOLs are associated with reduced chromatic dispersion. Hydrophobic IOL opacifications are caused by sub-surface glistenings, while hydrophilic IOL opacifications are due to surface calcifications. Some surgeries, including pars plana vitrectomy and lamellar corneal transplants, were shown to increase the risk of IOL calcifications, although the mechanism is still unknown. Hydrophilic IOLs have greater ease of manipulation, greater resistance to IOL damage, and higher uveal biocompatibility. Hydrophobic IOLs show better PCO prevention than hydrophilic IOLs, and should be preferred in highly myopic eyes where Nd:YAG capsulotomy might increase the risk of retinal detachment.","PeriodicalId":50604,"journal":{"name":"Current Opinion in Ophthalmology","volume":" ","pages":"18-24"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11620326/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142512326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A revised classification system has been introduced, reflecting the underlying principles of each formula. Recent comparative studies demonstrate the excellent refractive outcomes achievable with modern formulas. Emerging trends, such as the use of sum-of-segments axial length and the incorporation of measured posterior corneal data, hold promise for refining predictions in cases of extreme axial lengths and nonphysiological corneas, respectively. Advances in optimization and analytical methods also have the potential to further enhance refractive results.Summary: The field of IOL power calculation is continually evolving through iterative improvements in formula design, driven by new technologies, advanced instrumentation, and innovative analytical approaches.

We are only at the tip of the iceberg in utilizing the abilities of artificial intelligence in medicine to improve accuracy of diagnoses and to enhance patient outcomes. Artificial intelligence has allowed better image analysis, prediction of progression of disease, personalized treatment plans, incorporations of genomics, and improved efficiency in care and follow-up utilizing home monitoring. In ocular health diagnosis and treatment of diabetic retinopathy, macular degeneration, glaucoma, corneal infections, and ectasia are only a few examples of how the power of artificial intelligence has been harnessed.
