Visual Outcomes and Postoperative Complications of ACIOL vs. SFIOL: A Prospective Comparative Study

Anterior chamber intraocular lens and scleral fixated intraocular lens are key options for patients without capsular support, necessitating a comparison of their visual outcomes and complications. Objectives: To analyze and contrast the postoperative visual results and complications amongst patients who underwent cataract surgery or secondary lens implantation and received either an anterior chamber intraocular lens or a scleral fixated intraocular lens. Methods: The total number of participants was n=120: Group I involved 60 eyes that received an anterior chamber intraocular lens while Group II involved 60 eyes that were given a scleral fixated intraocular lens. The primary outcomes measured were best-corrected visual acuity before the procedure and then at 1-, 3-, and 6-months post-op, whereas secondary outcomes included complications such as inflammation, elevated intraocular pressure, dislocation of the artificial intraocular lens, as well as other postoperative adverse events. SPSS 23 was used. Results: At the 6-month mark, both groups demonstrated significant improvement in best-corrected visual acuity compared to pre-op levels, with no noteworthy difference in final visual acuity between those who received an anterior chamber intraocular lens versus a scleral fixated intraocular lens. The mean best-corrected visual acuity for Group I was 6/9 whereas Group II presented with a mean best-corrected visual acuity of 6/12 (p>0.05). No significant discrepancies in complication rates were observed between the two procedures. Conclusions: It was concluded that anterior chamber intraocular lens implantation and scleral fixated intraocular lens implantation can yield positive visual outcomes for patients undergoing cataract surgery or secondary lens implantation.
