Comparison of Outcomes between Scleral Fixated Versus Anterior Chamber Intraocular Lens Implantation in Aphakic Patients

Abstract

Purpose:  To compare the visual outcomes and early postoperative complications of Scleral fixated intra-ocular lens (SFIOL) implantation versus anterior chamber intra-ocular lens (ACIOL) in aphakic patients.

Study Design:  Quasi-experimental study.

Place and Duration of Study:  Al Shifa Trust Eye Hospital, Kohat, from February to July 2025.

Methods:  This study included 59 aphakic patients, aged 18-70 years. Patients with pre-existing retinal disorders such as macular degeneration or retinal detachment, those with severe corneal opacities or glaucoma, individuals with uncontrolled systemic illnesses (such as poorly managed diabetes or hypertension), and anyone with a recent history (within the last six months) of ocular trauma or infection were excluded. The study patients were recruited and divided into either the SFIOL or ACIOL groups through convenient sampling. Complete ocular examination included Best-corrected visual acuity (BCVA converted to LogMAR), intraocular pressure, slit lamp examination, fundoscopy and post-operative complications. Data was analysed using SPSS-27. The Mann-Whitney U test and chi-square or Fisher's exact test, (considering p ≤ 0.05 as statistically significant), were applied.

Results:  The median age was 62 years (IQR: 54–70), and 66.1% were male. Postoperative BCVA improved in both groups, with no statistically significant difference (p = 0.086). ACIOL was associated with higher rates of Hyphema (p = 0.011) and vitreous incarceration (p = 0.024). Severe uveitis, IOL capture, and retinal detachment showed no significant intergroup differences.

Conclusion:  Both SFIOL and ACIOL are effective in restoring vision in aphakic patients. However, ACIOLs are related to a higher rate of early postoperative complications.
