Our study retrospectively reviewed the surgical outcomes up to 3mo of 38 consecutive Chinese glaucoma patients who underwent trabeculectomy ( n =18) or phacotrabeculectomy ( n =20). Baseline age, visual acuity, and intraocular pressure were comparable. Intraocular pressure from post-operative 1d to 3mo were similar between 2 groups. Complete success was achieved in 65% of phacotrabeculectomy, and 66.7% of trabeculectomy cases; while failure occurred in 16.7% of phacotrabeculectomy, and 10% of trabeculectomy cases at 3mo. Phacotrabeculectomy group consistently showed better improvement in visual acuity. Diffuse blebs occurred in 65% of phacotrabeculectomy and 83% of trabeculectomy eyes; and flat blebs in 35% of phacotrabeculectomy, but none after trabeculectomy. There was more hypotony (5% vs 0) after phacotrabeculectomy. To conclude, phacotrabeculectomy and trabeculectomy demonstrated comparable intraocular pressure control up to 3mo post-operatively. However, phacotrabeculectomy patients had better visual acuity improvement. Nonetheless, more diffuse bleb and less hypotony were present following trabeculectomy.
