ABSTRACT
Purpose@#The aim of this study was to determine the surgical and visual outcomes of scleral fixated intraocular lens implantation in eyes with as subluxated and dislocated crystalline lens or traumatic aphakic eyes.@*Methods@#A retrospective and short-term prospective cohort study was carried out in 45 eyes of 43 individuals who underwent SFIOL implantation surgery in First Central Hospital of Mongolia between January 2017 and January 2020 and had a minimum follow-up of 3 months. Pre-operative and post-operative best corrected visual acuity, postoperative outcomes and complications were summarized. Patients after the implantation of a scleral fixated PCIOL were evaluated for the disease etiology, pre- and post-operative best corrected visual acuity, and occurrence of postoperative complications.@*Results@#The analysis included 45 eyes from 43 patients. Thirty-two (74.4%) patients were men and eleven (24.6%) were women . The mean age at implantation was 57.2 ± 20.0. Indications for the IOL implantation included ocular trauma (48.9%), pseudoexfoliation syndrome (22.2%) and Marfan syndrome (15.6%). Disease etiology and age group were compared and results were Marfan syndrome is mostly diagnosed in 20-29 years of age, ocular trauma is usually diagnosed in 30-69 years of age and pseudoexfoliation syndrome is occurred in 70 and above of age. Post-operative visual acuity was improved in all cases from which 35 of patients (77.77%) visual outcome was 6/12 and above. </br> The mean preoperative best corrected visual acuity (BCVA) was 0.083 ± 0.088, which improved to 0.569 ± 0.221 (p<0.001) third month postoperatively and these were statistically significant.</br> The most frequent complication was induced astigmatism, which occurred in 6 eyes which successfully corrected with glasses. Suture erosion occurred in three eyes which successfully relocate it. The most serious complications such as vitreous hemorrhage, retinal detachment, suprachoroidal hemorrhage, endophthalmitis and suture degradation or breakage was not seen.@*Conclusion@#Ab externo SFIOL implantation is a reasonable technique for the management of eyes with aphakia or absence of capsular support, with relatively high visual outcomes and few serious complications.</br> The most frequent cause of aphakia and absence of capsular support was ocular trauma thus, pseudoexfoliation and Marfan syndrome were the most common in elderly and in young age, respectively.
