Abstract

Purpose

To study long-term visual and refractive outcomes and complications in eyes with anterior chamber intraocular lens (ACIOL) implantation.

Methods

Data of patients who underwent primary and secondary ACIOL implantation at L V Prasad Eye Institute, Bhubaneswar between 2011 and 2020 was collected, including details of post-operative visits. For analysis, sample was divided into: group Ia (primary ACIOL in cases without risk factors, n = 104); group Ib (primary ACIOL in cases with pre-existing risk factors, n = 49); and group II (secondary ACIOL, n = 40).

Results

A total of 193 eyes of 192 patients were included. Mean post-operative follow-up in groups I and II were 8.6 and 11.51 months, respectively. Mean pre-operative and last visit corrected distance visual acuity were 1.73 ± 0.11 and 0.42 ± 0.05 logMAR units in group Ia (p < 0.001), and 1.53 ± 0.14 and 0.49 ± 0.10 logMAR units in group Ib (p < 0.001). The mean spherical equivalent (MSE) for last refraction was −0.37 ± 0.18 diopters (D) and −0.15 ± 0.51 D in groups I and II, respectively. Of 76 eyes in which addition of 2.5 D (over the near emmetropic posterior chamber intraocular lens power) was taken for ACIOL, 40 (52.6%) had MSE within ± 0.5 D. Most common complications were transient corneal edema and anterior chamber reaction. Eyes on anti-glaucoma medications at last visit were eight (7.7%), 15 (30.6%), and two (5.0%) in groups Ia, Ib, and II, respectively.

Conclusion

We observed that ACIOLs have good visual and refractive outcomes. Raised IOP is a concern in eyes with pseudoexfoliation, but can be managed with close monitoring. Hence ACIOL can be a good option for managing aphakia after cataract surgery.
