About the Procedure
Posterior segment surgery encompasses vitreoretinal procedures on the vitreous, retina and macula – from retinal detachment to macular holes, diabetic retinopathy, epiretinal membranes and complex trauma sequelae. Few disciplines in ophthalmic surgery demand more: the most delicate anatomical structures, limited intraoperative visibility and a multitude of coordinated steps require the highest level of precision – and a technique that is reliable at every moment.
Geuder meets this demand with something rare: a complete system from one source. Device platform, endoillumination, laser, single-use material and high-purity tamponades are fully coordinated – developed, manufactured and tested to the same standard.
megaTRON S4 HPS – The Core System for the Posterior Segment
Complex procedures demand a system that maintains overview. The modular megaTRON S4 HPS covers anterior and posterior segment, coordinating vitrectors, endolaser, illumination and infusion in one platform – the technical foundation on which demanding vitreoretinal surgery finds its calm.
- 1. Integrated Complete System — Vitrectomy, endolaser, illumination and infusion in one system – coordinated, not just combined.
- 2. Precise Fluidics — The hybrid pump combining peristaltic and venturi technology provides every phase of surgery with the fluidics it demands.
- 3. Modular Application — One platform for anterior and posterior segment – investment security for every OR.

Our System for the Posterior Segment
Vitrectors & Trocar Systems
The UNO Colorline single-use system covers all common access systems from 20G to 27G – including trocar systems, vitrectors, scissors and forceps for a gentle, efficient vitrectomy manoeuvre.
Endoillumination
The SOLEA® RGB-LED light source and the xenoTRON® III xenon light source reveal tissue that other light sources conceal – with an integrated Phototox Guard to protect the retina.
Endolaser & Laser Probes
The endoTRON 532 endolaser enables intraoperative laser coagulation of retinal tears and proliferative changes – integrated in the megaTRON S4 HPS or as a stand-alone system.
Tamponades & Dyes
High-purity silicone oils, PFCL and preloaded gas tamponades from our subsidiary Fluoron – for intraoperative and long-term management of retinal detachments and macular holes.
Buckling Surgery
Specialised buckling implants for scleral-supported procedures in retinal detachment surgery – for a precise, tissue-sparing approach.
