PURPOSE To present an electrocoagulation fixation technique for one-piece intraocular lens (IOL) scleral flapless fixation with sutures without knots. METHODS First of all, after repeated tests and comparisons, we chose 8-0 polypropylene suture as the material for electrocoagulation fixation of one-piece IOL haptics, because of its proper elasticity and size. A transscleral tunnel puncture at the pars plana was performed using an arc-shaped needle with 8-0 polypropylene suture. The suture was subsequently guided out of the corneal incision by a 1ml syringe needle, and then guided by the needle into the inferior haptics of the IOL. The suture was cut off and heated into a probe shape with a spherical tip using monopolar coagulation device to prevent slippage from the haptics. RESULTS In the end, 10 eyes underwent our new surgical procedures, and the average operation time was 42.5 ± 12.4 minutes. At 6-month follow-up, 7 of 10 eyes achieved significant vision improvement, and 9 of 10 kept the implanted one-piece IOL stable in ciliary sulcus. No serious intra-/post-operative complications were observed. CONCLUSION The electrocoagulation fixation was a safe and effective alternative technique for previously implanted one-piece IOL scleral flapless fixation with sutures without knots.
