Abstract:

We produced a measurement apparatus for testing the tensile strength of wounds during cataract surgery, and tested the tensile strength of treated wounds including wounds sutured with various methods, non-sutured and wounds treated with various bio-tissue adhesives. Methods. In cataract surgery on white rabbits eyes, a corneoscleral incision 5 mm in length was made 2.5 mm from the limbus corneae, and entry into the anterior chamber was obtained 0.5 mm to the clear cornea. After treatment for closure, the corneoscleral piece was subjected to the tensile strength test. Results. The tensile strengths just after surgery were (1) 0 gf/mm^2 after self-sealing sutureless closure; (2) 114 gf/mm^2 after vertical suture closure (one stitch with 10-0 nylon); (3) 125 gf/mm^2 after horizontal suture closure (one stitch with 10-0 nylon); (4) 143 gf/mm^2 after infinity suture closure (with 10-0 nylon); (5) 112 gf/mm^2 after fibrin glue (Beriplast®P) application (instilled on the surface of scleral incision); (6) 121 gf/mm^2 after fibrin glue application (glued on corneoscleral wound); (7) 131 gf/mm^2 after cyanoacrylate closure (instilled on the surface of scleral incision); (8) 139 gf/mm^2 after cyanoacrylate closure (glued on corneoscleral wound). The respective strengths at four days after surgery were: (1) 86; (2) 131; (3) 137; (4) 175; (5) 109; (6) 43; (7) 138; and (8) 108 gf/mm^2. At 28 days after surgery, the respective strengths were (1) 164; (2) 167; (3) 184; (4) 209; (5) 322; (6) 195; (7) 251; and (8) 175 gf/mm^2. Conclusion. The use of fibrin glue in treatment of a wound in cataract surgery is beneficial in assisting this treatment.
