Abstract In cases where there is a lack of capsular support, intraocular lenses (IOLs) can be implanted in the anterior chamber and fixed to the iris or in the posterior chamber and fixed to the sclera, typically with a trans-scleral suture. Modern flexible open-loop anterior chamber intraocular lenses (IOLs) have a generally positive track record. However, there are still concerns regarding secondary glaucoma and loss of endothelial cells. These concerns are particularly significant in eyes that may have been exposed to trauma or complicated surgery, where the endothelium or anterior chamber angle may be compromised. Reports said that in patients with early endothelial cell loss and corneal decompensation, lens replacement with a posterior chamber intraocular lens (PC IOL) can prevent progression to bullous keratopathy. Scleral fixation intraocular lenses (IOL) are a good alternative, especially in cases of iris atrophy, traumatic mydriasis, or corneal endothelial problems. Compared to other types of IOLs, the relatively normal anatomical implantation site of scleral fixation IOLs results in fewer complications due to their placement away from the angle and corneal endothelium. Despite these advantages, suture-related complications such as suture exposure, rupture or erosion may occur, which can cause endophthalmitis or IOL instability respectively, so many ophthalmologists tried multiple techniques for implantation of stable SF IOL without the need for sutures. This work aims to evaluate the flanged sutureless intra-scleral haptic fixation technique for secondary IOL implantation regarding procedure difficulty, IOL centration and stability, intraoperative and postoperative complications and visual outcomes. The study included 22 patients with aphakia and absence of capsular support. It was conducted in the ophthalmology department of Menoufia University Hospital from April 2022 to April 2023 after receiving approval from the hospital’s ethical committee. |
