Full 3D Eye Modeling in the Diagnosis and Treatment of Lens Diseases With Eye Structures Disorders

In patients with complex cataracts, spatial abnormalities in the lens and its surrounding tissues-including both the anterior and posterior ocular segments-are often present. Due to the lack of precise preoperative assessment tools and standardized surgical protocols, these cases are associated with increased surgical complexity and difficulty, often leading to suboptimal visual outcomes. Therefore, this study explores a three-dimensional reconstruction method for the anterior segment based on swept-source optical coherence tomography (SS-OCT). By integrating imaging data from CT, B-scan ultrasound, and ultrasound biomicroscopy (UBM), a full three-dimensional model of the eye is constructed to enable objective and quantitative evaluation of its entire structure. This approach aims to provide valuable reference for surgical planning and prognostic assessment in lens diseases accompanied by ocular spatial structural abnormalities.

Evaluating Presbyopia-Correcting IOLs in Complex Cataract Cases With Anterior Segment Abnormalities

The goal of cataract surgery has evolved from simply restoring sight to providing clear and comfortable full-range vision. Traditionally, monofocal IOLs remain the routine choice for special cases with anterior segment abnormalities-such as lens subluxation, cataract with chronic uveitis, post-laser refractive cataract, and aphakia with insufficient capsular support. However, there is a growing demand among these patients for improved visual quality and spectacle independence.Currently, various presbyopia-correcting IOLs offer distinct advantages, providing more personalized options. The introduction and application of intraoperative optical coherence tomography (iOCT) ensures effective intraoperative monitoring. These advances make the precise implantation of presbyopia-correcting IOLs a promising extension to phacoemulsification in complex cataracts with anterior segment abnormalities. Nevertheless, their exact benefits regarding visual quality, safety, and patient satisfaction require systematic evaluation through rigorous prospective studies and long-term follow-up. Under strict perioperative management, this study will employ iOCT to monitor the accurate implantation of presbyopia-correcting IOLs and will assess postoperative visual quality and patient satisfaction.

Study on the Application of Adaptive Fluidics Technology in Lens Diseases Surgery

In phacoemulsification surgery for lens diseases using a traditional fluidics technology with a fixed perfusion pressure, the moment the perfusion needle enters the anterior chamber, the intraocular pressure will increase sharply. Moreover, the perfusion pressure cannot change along with the intraocular pressure during the operation, giving rise to many risks and threatening the safety of the surgery. The aim of this study is to apply adaptive fluidics technology to dynamically and precisely regulate the pressure and flow rate of the perfusion fluid, maintaining a relatively stable intraocular pressure during the operation. Meanwhile, intraoperative optical coherence tomography（OCT）was utilized to assist in observing the intraocular conditions, to study the advantages of adaptive fluidics technology in maintaining anterior chamber stability, and to verify the clinical application value of this technology in different types of lens diseases.

Study on the Application of Intraoperative Optical Coherence Tomography Technique in the Diagnosis and Treatment of Lens Diseases

Accurately assessing and dealing with anterior segment changes in the eyes of patients with lens diseases can better guide the operation details during surgery and make reasonable plans for possible intraoperative and postoperative complications. Applying the intraoperative optical coherence tomography technique, this study analyzes the correlation between preoperative, intraoperative anterior segment structural changes and postoperative surgical effects in patients with lens diseases, and evaluates the clinical benefits of intraoperative optical coherence tomography technique in lens surgery. This study is intended to further improve the diagnosis and treatment quality of clinical lens diseases.
