    Objectives: To define a haptic modification technique to increase the overall length of the intraocular lens (IOL) and evaluate the postoperative outcomes of patients in whom this technique was applied.Materials and Methods: The preoperative and postoperative characteristics of patients who underwent modified IOL implantation into the sulcus between May 2019 and December 2019 were evaluated. Modified Sensar AR40e lenses with hydrophobic acrylic optic and polymethylmethacrylate haptics were implanted to all eyes. Before implanting the IOL, the haptics were grasped with two toothless forceps and bent to elongate the total diameter of the IOL from 13.0 mm to 14.5 mm.Results: The study included 11 eyes of 11 patients who underwent modified three-piece IOL implantation into the sulcus due to insufficient capsular support. The mean age of the patients was 53.9 +/- 12.2 years. The mean axial length was 24.13 +/- 1.93 mm. Sulcus implantation was required due to aphakia in 9 eyes and IOL dislocation in 2 eyes. No haptic breakage occurred during the IOL modification technique or implantation. The mean preoperative best corrected visual acuity (BCVA) was 0.88 +/- 1.1 logMAR, while postoperative BCVA was 0.28 +/- 0.30 logMAR. No IOL dislocation or decentration was observed during 6-month postoperative follow-up.Conclusion: The larger diameter lenses obtained with this inexpensive and easily applicable technique may allow a more stable sulcus implantation in eyes with inadequate capsular support.

    A modified continuous suturing technique for amniotic membrane fixation after chemical corneal injury: An octagonal graft
    (Galenos Publ House, 2022-10-01) Baykara, Mehmet; BAYKARA, MEHMET; Sarı, Esin Söğütlü; SÖĞÜTLÜ SARI, ESİN; Yurttaş, Ceren; YURTTAŞ, CEREN; Kırıştıoğlu, Mehmet Ömer; KIRIŞTIOĞLU, MEHMET ÖMER; Tıp Fakültesi; Oftalmoloji Ana Bilim Dalı; 0000-0002-5555-1649; JBU-3309-2023
    This case report aims to describe a modified continuous suturing technique for firm fixation of a human amniotic membrane graft in a patient with persistent epithelial defect (PED) after a chemical eye injury. As a result of this technique, the amniotic membrane (AM) was firmly fixed to the corneal surface with eight continuous and locked episcleral sutures that resembled an octagon graft. This technique was performed in a 14-year-old patient with PED after a chemical corneal burn. Three weeks after the surgery, the PED was completely healed. This simple continuous suturing technique can allow firm and stable fixation of AM grafts on the ocular surface in cases of PED after chemical burn. It may prevent early loss of the graft and facilitate corneal epithelial wound healing.
