“…It means that phacotrabeculectomy was effective not only for IOP control but also for stable refractive outcomes. Previous studies reported that myopic shift occurs after phacotrabeculectomy compared to phacoemulsi cation alone [11,[23][24][25]. A decreased ACD after trabeculectomy causes a myopic shift, and a decreased AL after trabeculectomy causes a hyperopic shift, conversely.…”

“…Most of the studies that focused the refractive outcomes of phacotrabeculectomy analyzed only shortterm refractive outcomes less than 6 months [11,18,[22][23][24][25], and one study reported by Chung et al [12] had a limitation that the follow-up period of the control group was average of 4.81 months. Therefore, the present study is clinically signi cant because we analyzed long-term refractive outcomes of phacotrabeculectomy up to 24 months postoperatively.…”

“…As the calculations for IOL power improve due to the development of preoperative evaluations and surgical techniques, refractive outcomes are becoming more predictable [22,23]. There is increasing interest in reducing refractive errors after phacotrabeculectomy because trabeculectomy can affect refractive outcomes after phacoemulsi cation.…”

Background: To investigate long-term refractive outcomes after phacotrabeculectomy and to determine risk factors that may cause unstable refractive outcomes after phacotrabeculectomy in glaucoma patients.Methods: A total 120 eyes of 120 patients who had underwent uncomplicated phacotrabeculectomy (combined group) or phacoemulsification (phaco-only group) were included. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) were measured before and after surgery, and anterior segment parameters including anterior chamber depth (ACD), lens vault (LV), and anterior vault (AV) measured using anterior-segment optical coherence tomography were compared between the two groups. The mean absolute error (MAE) at 3, 6, 12, and 24 months postoperatively were compared. Risk factors associated with unstable refractive outcomes (MAE ≥ 0.5) were investigated in the combined group.Results: In both groups, BCVA was improved and IOP was decreased significantly. MAE at 3, 6, 12, 24 months postoperatively were not significantly different between two groups. The risk factors for unstable refractive outcomes after 12 months of phacotrabeculectomy were old age and LV. Whereas, the only factor predicting unstable refractive outcome after 24 months of phacotrabeculectomy was LV. The cut-off value of LV for predicting unstable refractive outcome analyzed by the ROC curve was 0.855 mm.Conclusions: Phacotrabeculectomy may be an effective treatment with predictable long-term refractive outcomes similar to phacoemulsification in patients with glaucoma. However, elderly patients or patients with large LV may be predisposed to unpredictable postoperative refractive outcomes after phacotrabeculectomy.
