PURPOSE: To introduce a modified intrascleral suture technique (MIST) for repairing iridodialysis combined with phacoemulsification cataract surgery and evaluate its efficacy.
METHODS: We retrospectively analyzed the clinical characteristics and surgical outcomes of patients undergoing iridodialysis repair and cataract surgery (2018-2023). Twelve eyes received MIST, and eleven received the modified sewing-machine technique (MSMT). Both techniques utilized the closed-chamber sewing-machine principle of suture loop formation. MIST utilized a 10-0 polypropylene suture with long straight and short curved needles, guided by a 26-gauge syringe tip for intrascleral suturing. MSMT involved creating a partial-thickness scleral tunnel, through which a prethreaded needle with 10-0 polypropylene suture was passed for fixation.
RESULTS: Iridodialysis was successfully repaired in all patients. The median procedure time was significantly shorter in the MIST group (25 min, IQR: 24.0-27.5) than in the MSMT group (34 min, IQR: 29.0-35.0; p < 0.0001). Although postoperative day 1 best-corrected visual acuity (BCVA) did not differ significantly between groups (p = 0.08), the median BCVA was better in the MIST group (0.1 logMAR, IQR: 0.0-0.4) than the MSMT group (0.4 logMAR, IQR: 0.1-0.6). Complication rates were comparable between groups.
CONCLUSION: The MIST technique provides a minimally invasive alternative for iridodialysis repair by eliminating the need for conjunctival or scleral dissection. This approach significantly reduces operative time while maintaining surgical efficacy and safety, making it a valuable option for combined iridodialysis and cataract surgery.
