Clinical Analysis of Visual Stability of Accommodating IOL Over 1 Year
Purpose
The purpose of this project is to assess the clinical outcomes and visual stability at distance and near of Crystalens AO 6-12 months postoperatively using one drop of intraoperative atropine and a single interrupted 10-0 nylon suture for 10 days postoperatively.
Methods
This was a retrospective study done by one surgeon in one surgery center. 28 eyes of 14 patients receiving bilateral Crystalens AO implantation were included. Uncorrected and best corrected visual assessments at distance and near were done at 1 day, 1 week, 1 month and final assessment at 6-12 months. Spherical equivalents of the final refraction were averaged and compared to predicted postop refractions.
Results
At pod 1, uncorrected average distance and near visual acuities were 20/59.2 and 20/15. At pod 1 week uncorrected and best corrected average distance acuities were 20/59 and 20/23.7. Average uncorrected and best corrected near acuities were J4 and J1 at one week. At one month uncorrected and best corrected average near acuities were 20/40 and 20/19 with uncorrected and best corrected near acuities J5 and J1. At the final postop visits, 6-12 months postoperatively, average distance uncorrected and corrected acuities were 20/38 and 20/22. Final uncorrected and corrected near acuities were J8 and J1. Average spherical equivalent of the final manifest refraction was -.08 diopter and the delta of predicted postop refraction versus final average spherical equivalent was 0.6 diopters.
Conclusion
Accommodating lenses continue to improve to enhance and stabilize visual outcomes. Surgeons have worked to optimize intraoperative and postoperative regiments to achieve better clinical outcomes. Crystalens AO remained stable at distance with some erosion of near average acuities over one year. All patients were correctable with glasses to 20/25 and J2.
