Popis: Abstract Background This study aimed to investigate the safety and efficacy of the Yamane technique (flanged intrascleral haptic fixation with double-needle technique /FIHFT) for three-piece intraocular lens (IOL) implantation in Egyptian patients diagnosed with Marfan syndrome (MFS) presented with subluxated lenses (ectopia lentis, EL). Methods This was a retrospective evaluation of thirty-three patients who were diagnosed with MFS and had subluxated lenses in a total of forty eyes. Seven of these patients had bilateral subluxation. Lensectomy or phacoemulsification was performed with limited anterior vitrectomy, followed by IOL implantation using the FIHFT method. Data was collected from medical records, including preoperative and postoperative corrected distant visual acuity (CDVA) using logarithm of the minimal angle of resolution (log MAR), preoperative and postoperative refractions, intraoperative and postoperative complications, and follow-up periods. Results The mean age of patients in the study was 30.79 years, with a mean follow-up of 23.9 months. Post-surgery, the refractive sphere decreased significantly from -9.1 ± 1.4 diopter (D) to -1.4 ± 0.7 D, and cylinder measurements dropped from -4.5 ± 0.8 D to -1.4 ± 0.6 D. The spherical equivalent (SEQ) also declined from -11.4 ± 1.5 D to -2.1 ± 0.8 D. The CDVA improved from 0.80 ± 0.32 to 0.18 ± 0.10 log MAR (P
