Long-term biocompatibility and visual outcomes of a hydrophilic acrylic intraocular lens in patients with uveitis

To report the long-term visual outcomes and biocompatibility of a single-piece hydrophilic acrylic intraocular lens (IOL) in patients with uveitis having cataract surgery.

Tertiary referral center, Birmingham, United Kingdom.

Retrospective case review.

The review included consecutive uveitis patients in whom phacoemulsification and acrylic IOL implantation was performed by the same surgeon. Outcomes measures are reported as rate/eye-year and included visual acuity and signs of bioincompatibility.

The review identified 171 eyes (140 patients; mean age 51 years [range 16 to 85 years]) with uveitis. The mean follow-up was 3.8 years (range 0.9 to 10.3 years). Signs of uveal bioincompatibility were found in 31 eyes, with visually insignificant deposits on the IOL in 17 eyes. The rate of uveal bioincompatibility was 0.06/eye-year. Signs of capsule bioincompatibility were found in 107 (63%) of 171 eyes (0.31/eye-year). Posterior capsule opacification was documented in 102 eyes (0.29/eye-year); neodymium:YAG laser capsulotomy was required in 31 eyes (0.05/eye-year). The rate of failure to maintain a 3 logMAR line improvement in corrected distance visual acuity (CDVA) was 0.08/eye-year; to maintain better than 0.3 logMAR, 0.15/eye-year; and to maintain either, 0.04/eye-year. At 1 year, 85% of eyes had a CDVA of better than 0.3 logMAR or maintained a 3 logMAR-line improvement. Eyes with preexisting macular or optic nerve disease had significantly worse visual outcomes.

The long-term safety profile of the hydrophilic acrylic IOL was good in uveitis cases, leading to good visual outcomes and a low rate of vision-impairing uveal and capsule complications.
