OBJECTIVE: To evaluate the clinical outcome of burst mode phacoemulsification in eyes that had undergone glaucoma filtering surgery. METHODS: A randomized prospective study of 52 consecutive cases (68 eyes) of glaucomatous eyes after filtering surgery was conducted. The patients had similar intraocular pressure (IOP) and stages of cataract, and were matched in sex and age. All cases received phacoemulsification with posterior chamber intraocular lens implantation by one surgeon and randomly assigned to one of the two groups (the burst mode group and the continuous mode group). The effective phaco-time and the actual power were recorded. The visual acuity, corneal edema, IOP, and endothelial cell loss were compared between the two groups. RESULTS: The postoperative visual acuity of all patients improved in different degrees. The mean postoperative IOP increased by 0.81 mmHg in the burst mode group and by 1.17 mmHg in the continuous mode group. The functional filtering bleb was not apparently cicatrized. The mean effective phaco-time of the burst group was statistically shorter than that of the continuous mode group. The actual power of the burst group was statistically lower than that of the continuous mode group. Corneal clarity on the first and third postoperative day of the burst group was better in comparison to the continuous mode group. The mean endothelial cells loss in the burst group was significantly less than in the other group one week after surgery. CONCLUSION: Glaucomatous eyes with cataract after filtering operation can rehabilitate their visual acuity and maintain the functional filtering bleb by phacoemulsification with foldable intraocular lens implantation through a temporal clear corneal incision. The use of burst mode phaco-power reduces significantly the effective phaco-time and the amount of ultrasound energy. The decreased energy utilization has significant benefits including diminished injury to surrounding ocular structures, less corneal edema, endothelial cells loss and rapid visual rehabilitation.
