Abstract Background Implantation of intraocular lens in the capsular bag has become the standard of care in aphakic state. However, in the absence of capsular support, several techniques and intraocular lenses are available. Our study aims to report the safety, efficacy, and clinical outcomes of transconjunctival intrascleral intraocular lens fixation with Yamane’s double-needle technique and flanged haptics. Methods Prospective, observational study with some retrospective data collection. The study enrolled 13 patients (16 eyes) who underwent transconjunctival intrascleral fixation of an intraocular lens with Yamane’s technique between June 2017 and April 2019 at Dhahran Eye Specialist Hospital and King Fahd University Hospital. All patients underwent preoperative and postoperative comprehensive evaluation, including uncorrected and best-corrected vision, intraocular pressure, slit-lamp examination, dilated fundus examination, and ultrasound biomicroscopy. We excluded patients with visually significant coexistent pathology such as retinal diseases, glaucoma, follow-up less than three months, and combined surgery such as keratoplasty. Results The mean preoperative uncorrected visual acuity was 1.50 logMAR, and it improved to 0.60 logMAR. The mean preoperative best-corrected visual acuity was 0.70 logMAR, and it improved to 0.40 logMAR. The median safety index was 2.0, and the median efficacy index was 1.58. The postoperative complications included iris capture by the intraocular lens in one eye (7.7%), haptic extrusion in one eye (7.7%), and transient cornea edema in one eye (7.7%). There were no detected reports during the follow-up period of postoperative retinal detachment, choroidal detachment, elevation of the intraocular pressure (> 25 mmHg), hypotony, hyphema, vitreous hemorrhage, or endophthalmitis. Conclusions The transconjunctival intrascleral fixation of an intraocular lens is safe and effective with a short learning curve and was not associated with significant intraoperative or postoperative complications.
