Purpose
To describe the results of phacoemulsification and implantation of a light adjustable lens in patients with a history of previous incisional refractive surgery such as RK and AK.
Methods
Retrospective case series of 11 patients (16 eyes) with cataract and a history of RK and/or AK who underwent phacoemulsification with implantation of a light adjustable lens. Two weeks after the second eye surgery, the patients underwent adjustment by ultraviolet (UV) light. Postoperatively, manifest refraction, astigmatism, and spherical equivalent were recorded for all patients. The mean absolute error (MAE) and percentage of eyes within 0.5 D from target were calculated. Follow-up time was between 2 and 4 months.
Results
The mean absolute error MAE after adjustment was 0.31 D, and the % of eyes within 0.5 D after adjustment was 94% (15/16 eyes). Prior to adjusting the IOL, the MAE was 0.97 D and the % of eyes within 0.5 D was only 50%.
Conclusion
The Light Adjustable Lens works well in eyes with previous RK surgery, with refractive results superior to current technology such as intraoperative aberrometry and IOL formulae. Limitations of these data include sample size and length of follow up.
