Strauss Curriculum Drawings

Explore a series of free-hand drawings designed to illustrate essential principles of cataract surgery. These visuals are best utilized in the operating theatre for discussions among surgical teams. They complement Chapter 4, Section 1 of the MSICS curriculum, focusing on tunnel architecture, intraocular pressure, and capsulotomy techniques. Key notes include the suspension bridge-like configuration of the tunnel, the importance of external grooves for stabilization, and handling nucleus dislocation. A hands-on approach for better understanding and execution of complex procedures.

  1. Strauss Curriculum Drawings • Free hand drawings to be used to illustrate key principles • Best if used in the operating theatre for discussion • Use in conjunction with the MSICS curriculum Chapter 4 section 1, C.

  2. Tunnel Architecture -Note the suspension bridge-like configuration -Note the limbal straddling

  3. One way valve effect of the tunnel -Note 3 step configuration -Note importance of intraocular pressure to close the valve -Note use of external groove as the point to stabilize the tunnel if pressure is low

  4. Funnel effect of the tunnel -Note tendency of central tunnel to sag open -Note the external opening is a shorter chord length then internal

  5. Tunnel fulcrum for instruments -AC maintenance requires respecting internal opening as a fulcrum -minimize internal opening

  6. Nulceus dislocation into AC -note rounded side of nucleus acts as pivot point -note downward pressure with rotation will dislocate nucleus into AC -note adequate capsulotomy is needed

  7. Capsulotomy technique -note advantage of centripetal vs centrifugal tears -note capsulorhexis-like tear maneuvers -note large size of capsulotomy
