Every eye speculum trades exposure against pressure on the globe, and each pattern sits at a different point on that trade. Peak Surgicals stocks fourteen speculum patterns and three ophthalmic retractors, in German stainless steel and CE marked and built under ISO 13485. Compare every pattern in the grid below.
Wire or Solid Blade? Exposure Against Barrier
Wire and solid blades solve different problems, and the choice is not only about visibility. A wire blade is a thin high-tensile loop, so it holds the lid with very little material sitting on the globe and leaves the limbus and the incision unobstructed. That is why wire patterns dominate cataract and refractive work, where the phaco tip and the I/A handpiece both have to reach the wound without meeting the blade.
A solid blade does something a wire cannot: it forms a physical barrier between the lid margin and the field. Lashes and lid margin secretions stay outside the operative area, which matters because those secretions are a source of the organisms implicated in endophthalmitis. The blade is not just holding the lid open; it is keeping the lid's own flora away from an open eye. Against that it presents more surface to the globe. We supply every pattern at MOQ 1.
Spring or Screw? How the Retraction Is Held
The second decision is how retraction is held. Spring patterns rely on the memory of the metal itself: Barraquer Wire Speculum (PS-7400, $22.00), Barraquer Wire Eye Speculum (PS-7402, $24.75), Kratz Barraquer Wire Eye Speculum (PS-7404, $21.45), Thornton Wire Eye Speculum (PS-7406, $9.35) and Eye Wire Speculum (PS-2301, $22.00) all work this way, giving constant gentle tension with nothing to adjust and nothing to fail.
Screw patterns let the surgeon dial the tension in and lock it. That matters twice over: in tight lids or deep-set orbits where spring tension alone will not hold, and in any case where a patient may squeeze, because a locked speculum cannot be pushed out of the eye. Lieberman Eye Speculum (PS-7410, $46.20), Lieberman Eye Speculum 15mm Blades (PS-7412, $49.50), Lieberman Open Wire Eye Speculum (PS-7413, $93.50), Castroviejo Eye Speculum ($44.00), Cook Eye Speculum ($66.00), Lancaster Eye Speculum (PS-7408, $39.27), Schott Eye Speculum (PS-7414, $16.50) and Weiss Eye Speculum (PS-J-150, $27.50) carry adjustable mechanisms.
Blade Width, and Where Retractors Fit
Blade width is chosen against the patient rather than the procedure. Paediatric blades run around 10 to 11mm, adult blades 14 to 16mm, and wider blades up to 18mm buy visibility at the cost of lash coverage. A blade too wide for the palpebral aperture will not seat; one too narrow lets the lid roll over it.
Retractors work alongside the speculum rather than replacing it. Desmarres Lid Retractors (from $7.92) evert or hold a single lid where a speculum would be too much instrument, which is the standard approach for foreign body removal and lid examination. Knapp Lacrimal Sac Retractors (PS-7420, $9.90) and Agrikola Lacrimal Sac Retractor (PS-7421, $33.00) hold the wound open during dacryocystorhinostomy and other lacrimal work, where the field is a pocket rather than an exposed surface.
Material, Reprocessing and Certification
Every pattern is forged from German stainless steel and passivated for corrosion resistance across repeated cycles. The inspection point is the blade edge and the spring or screw: run a gloved finger along both blades to check for burrs or roughened metal, because that surface rests against conjunctiva for the length of a procedure, and check wire blades for any bend that would change the seat. On spring patterns, open and release the arms and confirm they return to their original spread, since a fatigued spring holds less than it should. On screw patterns, run the screw through full travel and confirm it locks without slipping. Clean immediately with a neutral-pH enzymatic solution, working around the screw thread and blade junctions, then rinse with deionised water and dry fully before autoclaving at 134°C.
