Long-term outcomes of prediction error after combined phacoemulsification and trabeculectomy in glaucoma patients

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