Age-Related Cataract Clinical Trial
Official title:
The Application of Lens Dysfunction Index (DLI) in the Timing of Age-related Cataract Surgery
Before cataract surgery, subjects in the observation group used iTrace ocular aberration analyzer（itracey Technologies）and IOL-Master 700 biometer to measure the preoperative DLI(Dysfunctional lens index) and SS-OCT image of the lens, and The researchers used the anterior segment slit lamp to take photos of the anterior segment of the subject's lens in a state of dilated pupils .and self-scoring of the preoperative visual quality assessment scale. Healthy subjects in the control group also need to complete the above inspections. After that, three experienced cataract specialist surgeons combined the preoperative optometry data of each subject, the photos of the LOCS III anterior segment and the Catquest-9SF questionnaire score to determine whether each subjects should undergo cataract surgery. The subjects were divided into cataract surgery group and non-surgical group. Finally, statistically study the correlation between the DLI index and the degree of lens opacity that has been collected, and use the ROC curve to calculate the DLI as the best cut-off point of DLI to distinguish whether to perform cataract surgery.
