Spring-loaded syringe versus vitrectomy machine program for removing silicone oil after retinal detachment surgery

Vitrectomy Machine Versus Spring Loaded Syringe for Active Silicon Oil Extraxtion

NA · Sohag University · NCT07363889

This test compares a modified spring-loaded syringe with a vitrectomy-machine silicone oil extraction program to see which is faster and safer for people having silicone oil removed after pars plana vitrectomy.

What this trial studies

This interventional comparison enrolled 540 eyes from 505 patients who were prepared for silicone oil removal after prior pars plana vitrectomy for retinal detachment. All procedures used 23-gauge pars plana vitrectomy and were classified into two groups: removal using the Optikon vitrectomy device's built-in silicone oil extraction program or removal using a modified spring-loaded syringe. The study measured efficiency (for example extraction time and completeness) and safety (intraoperative and postoperative complications). Findings will indicate whether the simpler syringe technique matches the machine program in performance and safety.

Who should consider this trial

Good fit: Ideal candidates are patients with silicone-filled eyes scheduled for silicone oil removal after prior pars plana vitrectomy for retinal detachment who meet the listed inclusion and exclusion criteria.

Not a fit: Patients with recurrent retinal detachment, previous scleral buckling, prior glaucoma surgery, bleeding tendencies, or anterior staphyloma were excluded and are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, the spring-loaded syringe technique could offer a simpler, lower-cost, and equally safe option for silicone oil removal after retinal detachment surgery.

How similar studies have performed: Manual syringe techniques and machine-assisted silicone oil extraction have been reported previously, but direct large-scale comparisons of a modified spring-loaded syringe versus a vitrectomy device program are limited.
