The stopper-knot technique using expanded polytetrafluoroethylene (Gore-Tex) sutures offers a stable, high-integrity method for scleral fixation of a dislocated intraocular lens (IOL). Because Gore-Tex is nonabsorbable and exhibits excellent tensile strength, it provides long-term security with minimal suture degradation compared with traditional polypropylene. The stopper knot acts as a mechanical buffer, preventing suture slippage through the haptic eyelet or fixation point and reducing stress concentration on the IOL. When positioned within carefully created scleral support tunnels, the construct distributes load evenly and helps maintain centration of the optic, even in eyes with significant zonular loss. Clinically, this approach has been associated with reliable postoperative stability, low rates of tilt, and favorable visual outcomes. While the technique requires familiarity with suture-based fixation, it expands the options for salvaging a dislocated IOL in cases where capsule support is insufficient.
