Abstract
Purpose :
Previous studies have examined postoperative complications and visual outcomes following cataract surgery in patients with uveitis; however, refractive outcomes in this population have not been well delineated. Our study evaluates the refractive outcomes following uveitic cataract extraction and assesses for factors associated with deviation from the refractive target.
Methods :
We performed a single center retrospective chart review of patients with a history of uveitis undergoing cataract extraction between January 2016 and June 2019. Demographics, ocular history, biometry measurements and examination findings both pre and post-operatively were obtained. The difference between postoperative refractive error spherical equivalent and refractive target was determined for each eye. We tested for association between axial length, average keratometry, location of uveitis, presence of preoperative keratic precipitates or posterior synechiae, history of cystoid macular edema, postoperative macular edema, persistent inflammation one month postoperatively and postoperative deviation from target > 0.5 Diopters (D) using t-tests or Fisher’s exact tests.
Results :
We examined sixty-five eyes from 48 patients. Thirty eyes (46.2%) had a refractive outcome which deviated more than 0.5 D from the refractive goal, and 10 eyes (15.4%) deviated more than 1 D from the planned target. The mean difference from the refractive target was 0.6 ± 0.7 D (range 0-4.54 D). No significant association was identified between a refractive error more than 0.5 D from target and any of the tested variables.
Conclusions :
Following uveitic cataract surgery, a large portion of patients had a refractive outcome that deviated from the intended target. Additional study to better define risk factors for this variability in refractive outcome is required.
