Tokyo, Nov. 14 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000059770) titled 'Evaluation of Anterior Chamber Stability Using Unity VCS in Cataract Surgery' on Nov. 13.
Study Type:
Interventional
Study Design:
Basic Design - Single arm
Randomization - Non-randomized
Blinding - Open -no one is blinded
Control - Uncontrolled
Primary Sponsor:
Institute - Kyorin University School of Medicine
Condition:
Condition - Cataract
Classification by malignancy - Others
Genomic information - NO
Objective:
Narrative objectives1 - This prospective observational study used Unity VCS to continuously collect preoperative and intraoperative data from 50 cataract surgery cases, aiming to evaluate anterior chamber stability during cataract surgery. Anterior chamber stability was assessed using the Total Chamber Stability Score, determined from surgical videos. Additionally, intraoperative OCT recordings were used to evaluate angle movement.
Basic objectives2 - Efficacy
Intervention:
Interventions/Control_1 - Obtain informed consent
Classify nuclear hardness preoperatively using the EL classification with a slit-lamp microscope
Cataract surgery is performed by a single experienced surgeon (KT)
The anterior chamber stability score during cataract surgery is assessed from the surgical video. The score classification is as follows, with score 0 indicating the most stable state
0:No change in anterior chamber depth
1:Minimal change in anterior chamber depth (change in distance from the anterior capsule or posterior capsule to the corneal endothelium less than 50% of the tip diameter)
2: Significant change in anterior chamber depth (change in distance from the anterior surface of the nucleus or posterior capsule to the corneal endothelium less than 50% of the tip diameter)
3: Posterior capsule aspiration without posterior capsule rupture
4: Posterior capsule aspiration with posterior capsule rupture
・Intraoperative OCT
Intraoperative OCT recording shall be performed during surgery. The recorded intraoperative OCT video shall be used to analyze the angle of the anterior chamber over time using Dipp-MotionV Software (DITECT). Conditions where the angle is narrow or where there is significant fluctuation in the angle are considered unstable. Conditions where the angle is well-opened and where there is minimal fluctuation in the angle are considered stable
