Background: To compare refractive outcomes after cataract surgery between patients with closed-angle and openangle\nglaucoma and evaluate the influence of preoperative factors on refractive outcomes in patients with glaucoma.\nMethods: Patients diagnosed with glaucoma and who underwent uncomplicated cataract surgery were enrolled in\nthis retrospective observational study. We collected data including age, history of prior laser peripheral iridotomy and\ntrabeculectomy, type of glaucoma, manifest refraction, intraocular pressure, axial length, and various anterior segment\nparameters using anterior-segment optical coherence tomography. Factors associated with unsatisfactory refractive\noutcome at postoperative 6 month were evaluated.\nResults: A total of 143 eyes (143 subjects) were included. Of these, 49 and 94 had closed-angle and open-angle\nglaucoma, respectively. At postoperative-6 month evaluation, the mean absolute error (MAE) predicted by the SRK-II\nand SRK-T formulae was 0.67 �± 0.61 and 0.81 �± 0.66 diopters (D), respectively. The overall predictability of achieving\nwithin �± 1.0 D of target was 76.92 % and 72.73 %, respectively. At a cutoff value of 1.0 D for MAE, there was no\nstatistical significant difference in refractive outcome between the closed-angle and open-angle glaucoma groups.\nLogistic regression modeling showed that large lens vault (LV) was a significant predictor of unsatisfactory refractive\noutcome after cataract surgery in patients with glaucoma.\nConclusions: When considering cataract surgery in patients with glaucoma, surgeons should recognize that the\nrefractive outcomes may be unsatisfactory in eyes with large LV.
