6/0 prolene double-flanged IOL sutureless scleral fixation with a 27-gauge needle for intraocular lens surgery.

Abstract

To report our initial experience of a modified intraocular lens (IOL) scleral fixation technique using 6/0 prolene in a double-flanged sutureless technique with a 27-gauge needle. 29 consecutive patients with IOL surgery were retrospectively reviewed between December 2021 and October 2023. Early Treatment Diabetic Retinopathy Study (ETDRS) letters, spherical equivalent (SE), astigmatism axial degree and intraocular pressure (IOP) were evaluated at baseline, and 1, 2, 3, and 6 months postoperatively. Surgery-related complications were evaluated during follow-up. ETDRS letters or SE at 1, 2, 3, and 6 months postoperation was significantly improved compared to baseline levels. Patients with younger (estimate [SE] = 8.011 [2.485], p = 0.006), preoperative lens drop (estimate [SE] = 8.621 [2.906], p = 0.009), idiopathic cataract (estimate [SE] = 6.021 [2.099], p = 0.048), high baseline ETDRS letters (estimate [SE] = 15.449 [2.352], p < 0.001), or low baseline SE (estimate [SE] = 6.357 [2.406], p = 0.018) had the greatest improvement in ETDRS letters during follow-up. Patients with preoperative lens or IOL dislocation had a greater postoperative SE improvement than those with preoperative lens or IOL subluxation (dislocation vs. subluxation: estimate [SE] = -189.235 [70.692], p = 0.016). There were no cases of vitreous hemorrhage, cystoid macular edema, endophthalmitis, subluxation or dislocation were observed during the 6-month follow-up. Our modified IOL scleral fixation technique is a simple, safe, efficient method that avoids haptic manipulation and slippage, reduces postoperative complications, achieves completely sutureless surgery, and results in an achievement of surgical refractive goals.
