Intraoperative Optical Coherence Tomography: Intraoperative optical coherence tomography technique can provide intraocular images and show changes in intraocular structures, assisting in analyzing the correlation between preoperative, intraoperative anterior segment structural changes and postoperative surgical effects in patients with lens diseases.
Study summary
This multicenter retrospective study will collect clinical data to investigate the associations between preoperative and intraoperative anterior segment structural changes and postoperative surgical outcomes in patients with lens disorders, and to evaluate the clinical benefits of intraoperative optical coherence tomography (iOCT) in lens surgery, with the aim of improving the diagnosis and treatment of lens-related diseases.

Inclusion Criteria:
* Aged 18 years or older.
* Presence of lens opacity or abnormal lens position.
* Visual impairment affecting activities of daily living.
* Met the indications for lens surgery.
* Underwent lens surgery.
Exclusion Criteria:
* Active intraocular inflammation.
* Uncontrolled systemic disease, use of medications that could significantly affect surgery, or other standard contraindications to lens surgery.
* Incomplete or unreliable key preoperative examination data, including ocular biometry.
* Inadequate image quality due to poor fixation or other causes, rendering the images unsuitable for analysis.
* Incomplete intraoperative OCT recordings, such as interrupted recording or severe image freezing, affecting data evaluation.
* Other psychological or physical conditions that might interfere with study participation.
Primary outcome measure(s)
Concordance Rate Between Preoperative and Intraoperative Diagnoses — From completion of the preoperative examinations through the end of surgery; diagnostic concordance is assessed after surgery. Preoperative diagnoses are determined based on routine ophthalmic examinations. Intraoperative diagnoses are determined based on surgical microscopic observations, intraoperative OCT images, and operative records. Concordance between the preoperative and intraoperative diagnoses is assessed, including whether the intraoperative diagnosis adds to or corrects the preoperative diagnosis.
