To compared with the efficacy of Tanito microhook trabeculotomy ab intrno combined with phacoemulsification and intraocular lens implantation (m-LOT) for prymaly open angle glaucoma (POAG) and cataract patients with differing preoperative intraocular pressure (IOP): high (H-IOP,≧20mmHg), middle (M-IOP, 15-19 mmHg), and low (L-IOP, ＜15 mmHg).

We analyzed the cases of 73 eyes of 73 patients with POAG and were followed up ≧3 months after m-LOT. Main outcome measurements were success rate, IOP, complications, and number of medications. Success was defined as IOP reduction＜20% from baseline IOP or IOP＜20 mm Hg, and no need for future glaucoma surgery.
Average age and medication score (S.D.) were 75.2 (7.1) years old and 1.8, respectively. Mean preoperative IOP (H-IOP, M-IOP, and L-IOP) were 24.8 (6.1), 17.2 (1.1), and 13.4 (1.3), respectively. In H-IOP and M-IOP, postoperative IOP were significantly decreased in any months after surgery compared with preoperative IOP (p＜0.01). In L-IOP, there was no significant deference of postoperative IOP compared with preoperative IOP. The cumulative success rate of H-IOP, M-IOP, and L-IOP were 87.3%, 36.3%, and 46.3% after 15 months of surgery, respectively. Visual acuity of all cases were improved compaired with baseline visual acuity. The complications included only transient IOP spikes (2.7%) and fibrin formation in anterior chamber (3.9%).
m-LOT is a safe and successful option for the treatment of POAG with various preoperative IOP. The surgical success could be maintained up to ~15 months.
