Dr. Seibel’s Inventions


As U.S. Patent holder Dr. Barry Seibel explains,

“The development of each of the 20 Seibel surgical instruments occurred while applying Phacodynamics principles to cataract and LASIK surgery. During each step of every operation, I ask myself what the goal of that moment is, and how it could best be served. If the answer is not the current technique and instrumentation, then I am driven to systematically derive how I can make improvements. This is how I created the 20 specialized Seibel instruments that enhance safety, patient comfort, and surgical efficiency.”

Flap Lifter

Seibel LASIK Flap Lifter

Very popular instrument used in LASIK, but also useful for refining astigmatism incisions created with a femto laser during cataract surgery. Also useful for opening prior incisions when a lens implant revision or exchange is needed.

Seibel Diamond Limbal Relaxing Incision Blade

Revolutionized Astigmatic Corneal Incisions by placing depth footplates at leading and trailing edges of blade instead of traditional blade flat position which either blocked ideal visualization or caused potentially erratic drag on instrument from adjacent conjunctiva. Used to refine astigmatism that is typically below lowest toric lens implant power.
Diamond Limbal
Rhexis Instrument

Seibel Rhexis Ruler with Microcoaxial Forceps

Two significant innovations. First, the ViewPort technology has tips that are uniquely machined to allow the surgeon to see what has been grasped when they are fully closed, overcoming that significant problem with prior instruments that block the surgeon’s view of what has been grasped. Second, the ruler markings allow for more accurate sizing of the capsulorhexis by measuring at the iris plane and significantly neutralizing corneal magnification.

Seibel Horizontal and Vertical Safety Choppers

These very popular instruments improve on prior art by critically analyzing both eye anatomy along with the mechanics of the chopping methods of cataract disassembly. For example, instead of the awkward and arbitrary right angle of the original chopping instrument, the Seibel instrument uses a curved architecture sized to the actual dimensions and curvature of a cataract. This not only allows for more effective engagement of the cataract during surgery, it also allows for much better ergonomics when entering and exiting the eye. The vertical chopping end is unique in incorporating a curved profile instead of the sharp tip more typical of this class of instruments. Adequate tissue cleavage is achieved by intelligent placement of the chopping bevel and a thin tip profile instead of the simpler but arguably more dangerous sharp tip of prior art instrumentation.

Eye Speculum

Seibel Gravity Fixation Ring

Used to stabilize the eye for various incisions, the original Fine Thornton Ring arbitrarily placed the handles pivots outside of the ring at the geometric center. The outside placement significantly increased the size of the instrument requiring a patient’s lids to be retracted more at greater discomfort. Furthermore, the central geometric placement meant that loose pivots caused the ring to sag awkwardly downwards and that stiffer pivots required two hands for positioning and placement. The Seibel instrument innovated by strategically placing the pivots on a tab above and inside the ring at the ring’s center of gravity, effectively improving the aforementioned problems with the original instrument.

Seibel 3D Eyelid

Prior art designs open in a flat plane, not respecting the lids natural arc of curvature which is like a visor rising over a helmet. In doing so, they distort the eyelids causing discomfort and potentially damaging eyelid muscles. The Seibel instrument was carefully reverse engineered to follow the natural arc of eyelid movement, uniquely using a ball joint to facilitate this movement. Also, the flat ribbon shape of the Seibel tips are designed to further enhance patient comfort by distributing force over a larger surface area as compared to the much more common wire tips that exert more pinching pressure on the lids.

Seibel 3-D Lid Speculum
– Solid Blade



Seibel 3-D Lid Speculum
– Ribbon Blade


Seibel 3-D Lid Speculum
– Ribbon Blade Compact


  • Unique pivot axis allows blades to gently support lids through an anatomically correct arc of motion.
  • Swivel screw adjustment mechanism rotates out of the way after adjustment and provides a secure lock.
  • Lid blades contoured to the surface of the eye are excellent for creating exposure of the eye surface during phacoemulsification or microkeratome suction ring placement.
  • Ribbon design of blades allows same surgical ergonomic access as open wire designs but the ribbon stock distributes force over a larger surface area than the tangent point of contact of a wire speculum, thereby reducing focal pressure on the eyelid and enhancing patient comfort.
  • Available in solid blade or open “ribbon” style blade.
  • Unlike conventional speculum designs that open in one plane, the blades of the Seibel 3-D Speculum follow the anatomical path of the globe to gently support the lids.
  • Screw mechanism swings up for positioning and adjustment and down out of the way during the procedure.
