Abstract:
Little evidence exists for prediction error in iris‐sutured intraocular lenses. Background To determine the magnitude of prediction error in iris‐sutured intraocular lenses, associated factors and their long‐term stability. Design Retrospective, nonrandomized, noncomparative case series conducted at the Wilmer Eye Institute (Baltimore, Maryland, United States). Participants Adult patients with subluxated intraocular lenses that underwent iris‐suture fixation between January 2000 and December 2014 by a single surgeon. Pregnant women, children (below the age of 18) and cases with follow‐up under 1 month were excluded. Methods Prediction error was calculated in 60 eyes and survival analysis was performed on 99 eyes. Main Outcome Measures Prediction error (the difference between the postoperative manifest refraction in spherical equivalent and the spherical equivalent predicted by the Barrett Universal II, Holladay 2 and SRK/T formulas), preoperative and postoperative distance‐corrected visual acuity, manifest refraction, frequency of postoperative complications and time until re‐subluxation. Results Mean prediction error using the Barrett formula was −0.35 ± 1.0 D. Higher axial length (≥25.5 mm) was associated with greater prediction error (−0.72 ± 1.11 D vs −0.18 ± 0.91 D, P = .048). Twelve re‐subluxations occurred over a mean follow‐up period of 30.28 ± 41.86 months. The predicted 50% survival of iris‐sutured lenses was 114.25 months. Conclusions and Relevance Iris‐suture fixation may require moderate lens power adjustment to compensate for prediction error, especially in eyes with higher axial length. Longer follow‐up demonstrates that iris‐suture fixation remains a viable technique, yet re‐subluxations require routine monitoring of such eyes.
