Abstract
PURPOSE To evaluate the outcomes and progress after phacotrabeculectomy at the same clinical setting and/or performed by the same surgeon over the past decade. SETTING Eye Institute of Utah, Salt Lake City, Utah, USA. METHODS This retrospective study included 60 eyes of 43 patients who had phacotrabeculectomy at a single institute between 1999 and 2005. A modified phacotrabeculectomy surgical technique was used that included a 2-site incision approach, fornix-based flap, use of mitomycin-C, acrylic intraocular lens implantation, sutured scleral and conjunctival flaps, and sutured temporal clear corneal incision. RESULTS Over a mean 30-month follow-up, 57 of the 60 eyes (95%) achieved intraocular pressure (IOP) control (<or=21 mm Hg) with or without medication. Thirty eyes (50%) had an IOP of 15 mm Hg or lower, and 34 (57%) had an IOP reduction of at least 30%. The IOP decreased from a preoperative mean of 23.1 mm Hg on a mean number of 1.67 glaucoma medications to a mean of 14.9 mm Hg on a mean of 0.23 medication at the final follow-up (P<.001 for IOP decrease and for reduction in number of medications). Fifty-two eyes (87%) obtained a best spectacle-corrected visual acuity of 20/40 or better. Dysesthetic blebs requiring surgical revision and bleb hemorrhage (each occurring in 2 eyes, 3.3%) were seen in this study, but not previous studies. CONCLUSIONS The surgical technique used in this study appears to be effective and superior to a previous technique at restoring visual acuity, lowering IOP, and reducing the postoperative complication rate. The observations are relevant in the context of improvements of technique over the past decade.

Abstract
AIM To report the safety and efficacy of intraoperative mitomycin (MMC) augmentation of combined phacoemulsification and deep sclerectomy (PDS). METHODS Retrospective, non-randomized, comparative, interventional case series of 119 eyes (63 with and 56 without MMC augmentation) of 119 patients who had PDS between September 2001 and April 2004. RESULTS The mean follow-up was 23 months (range 12-41 months). There were no differences in the baseline characteristics of the two groups except that patients from the phacoemulsification and deep sclerectomy with mitomycin C (PDS-MMC) group were on average, younger by 3 years (P=0.01). Two years after surgery, the probability of maintaining an IOP below 19 and 15 mmHg without glaucoma medications or needle revision was 76 and 62% in the PDS-MMC group and 62 and 45% in the PDS-no MMC group (P=0.02 and 0.04, respectively). Nd:YAG laser goniopuncture was performed in 71.4% of eyes in the PDS-no MMC and 61.9% of the PD-MMC group (P=0.33). Needle revision was performed in 21.4% of the PDS-no MMC and 17.4% of the PDS-MMC group (P=0.65). Ten patients (8.4%) lost more than two lines of Snellen's visual acuity during follow-up, with no difference between the groups. There were few serious complications related to MMC use (hypotony in one eye after laser goniopuncture). The overall incidence of transconjunctival oozing in the PDS-MMC group was 9.5% compared with 5.4% in the PDS-no MMC group. CONCLUSION This study demonstrates that augmentation of PDS with MMC is safe. MMC augmentation appears to increase the probability of achieving lower target intraocular pressures after combined PDS.

Abstract
A case of early-onset sclerolimbal ectasia following low-dose topical mitomycin C application during uveitic glaucoma surgery is reported. Intraoperative and postoperative clinical courses were consistent with sclerolimbal ectasia. Adjunctive utilization of intraoperative low-dose 0.02% mitomycin C for the management of chronic uveitic glaucoma patients who are under concomitant systemic immunosuppressive regimen may enhance the risk of subacute postoperative sclerolimbal ectasia. Mitomycin C concentrations < 0.02%, decreased scleral exposure time, and a strict informed consent policy are strongly recommended in this subset of uveitic patients.

Abstract
PURPOSE To investigate the long-term success and complications of phacoemulsification combined with viscocanalostomy (phacoviscocanalostomy) in eyes with coexisting cataract and medically uncontrolled glaucoma. SETTING Department of Ophthalmology, Warrington Hospital, Warrington, United Kingdom. METHODS A prospective nonrandomized study evaluated 165 consecutive eyes (114 patients) that had phacoviscocanalostomy. The main outcome measures were intraocular pressure (IOP), visual acuity, requirement for topical antiglaucoma medication, and the presence or absence of drainage blebs or bleb complications. RESULTS The mean follow-up was 38.7 months +/- 19.3 (SD) (range 12 to 90 months). There was a statistically significant decrease in IOP, from 24.1 +/- 5.1 mm Hg preoperatively to 13.8 +/- 8.1 mm Hg 1 day after surgery (P<.001), 16.0 +/- 4.1 mm Hg at 5 years (P<.001), and at all evaluations to the last follow-up. The mean number of medications per eye decreased significantly from 2.5 +/- 0.9 before surgery to 0.1 +/- 0.5 at last follow-up (P<.001). At the final follow-up, IOP was reduced by 33.2% (16.2 mm Hg versus 24.1 mm Hg). Complete success, defined as an IOP reduction of more than 30% from preoperative level without medications, was achieved in 48.5% of eyes, with 42% of eyes having an IOP of less than 16 mm Hg. The percentage fall in IOP was linearly related to the preoperative IOP level (P<.001). No eye developed a trabeculectomy-type bleb, and there were no bleb-related complications. CONCLUSIONS Phacoviscocanalostomy was safe and effective for the management of eyes with coexisting cataract and medically uncontrolled glaucoma. It provided a stable and sustained reduction in IOP with a minimum requirement for topical medication.

Abstract
PURPOSE Combined surgery for glaucoma and cataract may not achieve as low intraocular pressure (IOP) as compared with trabeculectomy alone. The aim of this study was to assess the IOP control of 5-fluorouracil (5FU) phacotrabeculectomies compared with 5-fluorouracil trabeculectomies. METHODS A retrospective, nonrandomized study of consecutive primary 5FU phacotrabeculectomies and primary 5FU trabeculectomies. The main outcome measures were preoperative and postoperative IOP, number of medications, visual acuity, and complications. RESULTS Forty-five 5FU phacotrabeculectomies and 47 5FU trabeculectomies were performed with a mean follow-up of 43.1 and 36.6 months, respectively. The absolute success rate as defined as an IOP equal to or less than 16 mm Hg on no glaucoma drops was 62.2% for the phacotrabeculectomy group and 63.8% for the trabeculectomy group. These success rates were not statistically significantly different (log-rank test P = 0.81 for absolute success and P = 0.29 for relative success). The magnitude of the treatment effect was found to be significantly greater in the T group compared with the PT group (a 44.6% reduction in IOP in the T group compared with a 31.2% reduction in the PT group). The phacotrabectomy group underwent significantly more postoperative 5FU injections compared with the trabeculectomy group (P = 0.008). CONCLUSIONS 5FU phacotrabeculectomy seems to be a safe and effective treatment option in terms of IOP control. Patients with both coexistent glaucoma and cataract could be considered for combined surgery.

Abstract
PURPOSE To evaluate the safety and efficacy of combined phacoemulsification, intraocular lens implantation, and trabeculectomy with mitomycin C for the management of uveitic complications. DESIGN Retrospective case-control study. METHODS We conducted a retrospective review of the records of 23 consecutive eyes with chronic noninfectious uveitis (uveitic group) and 43 nonuveitic eyes (control group) that had received primary phacotrabeculectomy. Mitomycin C was used in all the uveitic eyes. Considering the high preoperative intraocular pressure (IOP) of the uveitic group, nonuveitic eyes that had a preoperative IOP of >or=20 mm Hg or that had been given two or more medications were included in the control group. All patients were followed for at least one year. The main outcome measures were postoperative vision, IOP control, complications, and acute uveitis relapse rates. RESULTS Visual outcome of the uveitic group was similar to the control group. In the uveitic group, the success rate of IOP control (91.3% at one year, 84.8% at two years) was favorable but was significantly lower than in the control group (P = .0423). Complications were comparable between the groups. Primary surgical failure in the uveitic group was associated with the postoperative acute uveitis attack. In the uveitic group, the acute uveitis attack rate showed no change after surgery (P = .283). CONCLUSION With adequate inflammation suppression, phacotrabeculectomy with mitomycin C is an effective and safe therapeutic option for the management of secondary cataract and glaucoma in uveitic eyes. A lower surgical success rate of the uveitic group might be attributable to the postoperative inflammation recurrence.

Abstract
AIM To evaluate the combined phacoemulsification with acrylic intraocular lens implantation and trabeculectomy with releasable sutures, without the use of antimetabolites, performed by one surgeon. METHODS A retrospective analysis was performed on 251 eyes of 198 patients after a combined phaco/trabeculectomy procedure, followed up for an average of 16 months for vision, intraocular pressure (IOP), and number of glaucoma medications. Cox proportional hazard regression analysis provided measures of relative risk (RR) or hazards ratios and 95% confidence intervals (CIs) associated with the occurrence of several conditions or complications of surgery. RESULTS Mean preoperative variables were best corrected vision, 0.6 (SD 0.4) logMAR (20/80 Snellen); IOP, 18.7 (4.9) mm Hg; and number of glaucoma medications, 1.7 (0.8). Mean postoperative results were best corrected vision, 0.2 (0.4) logMAR (20/32 Snellen); IOP, 15.1 (3.2) mm Hg; and number of glaucoma medications, 0.3 (0.6). Postoperatively, the mean decreases from baseline were 19.2% for IOP and 84.1% for number of glaucoma medications; 85% of eyes required fewer glaucoma medications and 78% of eyes were medication free, with IOP control. There were no significant operative or postoperative complications. CONCLUSION Combined phacoemulsification and trabeculectomy with releasable sutures, in the absence of antimetabolites, is a safe, effective, and stable alternative for patients with cataracts and glaucoma.

Abstract
PURPOSE To compare intraocular pressure (IOP) control in eyes with or without clear corneal phacoemulsification following trabeculectomy. METHODS The study group included 30 eyes that underwent uneventful clear corneal phacoemulsification and foldable intraocular lens implantation following trabeculectomy without antimetabolites. Thirty eyes that had undergone filtering surgery without cataract extraction were selected as controls. Case and control groups were matched with respect to age, gender, IOP, number of glaucoma medications, glaucoma type (primary open-angle glaucoma/pseudoexfoliative glaucoma), trabeculectomy time and follow-up. Comparisons between the study and control groups (intergroup) and within the same group at different time-points (intragroup) were performed for IOP, glaucoma medications and bleb morphology. Success rates were investigated by Kaplan-Meier survival analysis and the factors influencing final success by logistic regression. RESULTS Intraocular pressure (p = 0.04) and glaucoma medications (p = 0.001) increased during an average follow-up of 26.1 +/- 9.9 months in both groups. Intragroup differences became statistically significant after the 6-month visit, but intergroup differences remained insignificant. Bleb height decreased significantly following phacoemulsification in the study group (p = 0.017). Success rates decreased with time in both groups, with no intergroup difference (p = 0.46). The final success rate was negatively correlated with IOP and number of glaucoma medications used at the study entry, while there was a positive correlation between the baseline and final success rates. CONCLUSION Trabeculectomy success decreased in a time-dependent manner in eyes with and without subsequent phacoemulsification. Uncomplicated clear corneal phacoemulsification was not found to have any additional unfavorable influence on IOP control in eyes with filtering blebs.

Abstract
AIMS To characterise changes in ocular dimensions after combined cataract operation and trabeculectomy with mitomycin C using separate incisions (combined operation). METHODS 24 consecutive eyes that had combined operation and 16 eyes that had cataract operation alone were enrolled. The axial lengths before and after operations were determined with non-contact optical coherence biometry. The intraocular pressures (IOP), axial lengths, corneal curvatures, and the expected and observed refractive errors before and after operations were compared. RESULTS After a combined operation, mean IOP was significantly reduced from 16.6 (SD 5.8) mm Hg to 10.9 (4.1) mm Hg (p<0.00001), and mean axial length was significantly shortened from 24.10 (0.98) mm to 23.98 (0.96) mm (p<0.00001). The mean axial length reduction after combined operation (117 (57) microm) was significantly larger than the reduction after cataract operation alone (75 (38) microm, p<0.02), and correlated significantly with the postoperative IOP (p<0.002). There was a mean with the rule surgically induced corneal astigmatism of 0.44 (0.83) dioptre by vector analysis, and a significant increase of mean keratometry reading of 0.23 (0.46) dioptre after a combined operation. However, there was no significant difference between the expected and observed refractive errors. CONCLUSIONS Despite an alteration of the axial length and corneal curvature, the refractive outcome after a combined operation did not differ significantly from the predicted refraction.

Abstract
PURPOSE To evaluate the efficacy and safety of a novel surgical approach, ab interno trabeculectomy, in a combined procedure (clear corneal phacoemulsification + ab interno trabeculectomy) for the management of concurrent cataract and glaucoma with prognostic factors for filtration failure. SETTING Department of Ophthalmology, Palmanova Hospital, Udine, Italy. METHODS A prospective noncomparative case series of 11 eyes of 11 consecutive cataract patients with medically uncontrolled primary open-angle glaucoma or pseudoexfoliation glaucoma was performed. Each patient had phacoemulsification + intraocular lens implantation + ab interno trabeculectomy, which consisted of a gonioscopically controlled ab interno removal of a quadrant (3 clock hours) of the trabecular meshwork. The main outcome measures were intraocular pressure (IOP), the number of antiglaucomatous medications used, and complications. RESULTS Ten patients completed a 3-year follow-up. One patient had further surgery because of poor IOP control; in this case, the last valid observation was carried forward for IOP calculation. Mean preoperative IOP and IOPs measured 1, 3, 6, 12, 24, and 36 months after surgery were 25.0, 15.8, 15.4, 15.4, 15.2, 15.0, and 15.3 (-38.56%) mm Hg respectively. The number of medications averaged 2.4 before surgery and dropped to 0.8 at the end of follow-up. No major complications occurred during the follow-up period. CONCLUSIONS The new surgical procedure combining phacoemulsification with ab interno trabeculectomy can induce a clinically relevant decrease in IOP in eyes with cataract and glaucoma with poor prognosis for filtering surgery. However, a randomized controlled clinical trial with a more extended follow-up and a larger series of patients is needed to ascertain the actual effectiveness and safety of this procedure.

Abstract
PURPOSE To compare IOP behavior after deep sclerectomy (DS) and trabeculectomy with the Crozafon-De Laage Punch (TP), using low-dosage intraoperative mitomycin C (MMC) in both techniques. METHODS The study was a prospective randomized clinical trial. All patients met inclusion and exclusion criteria, and were scheduled for glaucoma surgery. Forty patients were randomized to undergo either a nonpenetrating DS with MMC (DSMMC) (19 eyes) or a TP with MMC (TPMMC) (21 eyes). Postoperative examinations were performed at the 1st day, the 1st, 2nd and 3rd weeks and the 1st, 3rd, 6th, 9th and 12th months. Postoperative complications, number of antiglaucoma medications and the IOP level were checked at each control. Complete success (without antiglaucoma medications) and qualified success (with or without medications) were assessed at two target IOP levels, namely < or = 21 and < or = 17 mm Hg in both groups. Moreover, the success rates at < or = 21 mm Hg target IOP level were compared with those from previous series of patients who had undergone DS without MMC (historical control group). RESULTS Data from all eyes were available until the 12th month. The mean preoperative IOP +/- SD was 29.6 +/- 5.8 mm Hg in DSMMC eyes, 28.0 +/- 6.0 in TPMMC eyes; the mean IOP at the 1st postoperative day was 12.5 +/- 4.2 and 13.9 +/- 6.5 mm Hg, while at the endpoint the mean IOP was 14.5 +/- 4.0 and 16.1 +/- 3.8, respectively, with significant reduction (p < 0.0005) of the preoperative IOP in both groups. Complete success (< or = 21 mm Hg target IOP) in 15 eyes (78.9%) of the DSMMC group and in 15 eyes (71.4%) of the TPMMC group was respectively found, while qualified success was achieved in all the eyes. When a < or = 17 mm Hg target IOP was considered, complete success in 12 eyes (63.1%) and 13 eyes (61.9%), and qualified success in 13 eyes (68.4%) and 15 eyes (71.4%) were found in the DSMMC and TPMMC groups, respectively. No significant intergroup differences were found in terms of success rate. There is no statistical significance in the Kaplan-Meier cumulative survival curves as for complete and qualified success rate in both surgical groups for a < or = 17 mm Hg target IOP (log rank, p = 0.918 and p = 0.429, respectively). As for the frequency of postoperative complications, hypotony and shallow anterior chamber were significantly more frequent in TPMMC when compared with the DSMMC group. The historical comparison between the DSMMC group and simple DS cases shows no significant difference between the groups, with a mild positive trend in DSMMC when compared with DS eyes. CONCLUSIONS Both techniques, DSMMC and TPMMC, control IOP efficaciously at our endpoint. Our results indicate that low-dosage MMC can be considered a mild enhancement of DS IOP lowering effect without any negative effect on the well-known intra- and postoperative safety of the technique.

Abstract
AIM This study examines the changes in axial length (AL) after trabeculectomy and glaucoma drainage device (GDD) surgery and enabled an equation to be derived allowing prediction of AL change after filtering surgery. METHODS This was a prospective, interventional case series from the Glaucoma Service of the Doheny Eye Institute. PATIENT POPULATION One eye of 39 patients undergoing trabeculectomy and 22 undergoing Baerveldt tube shunt implantation for uncontrolled glaucoma. INTERVENTION These patients had AL measurements by non-contact, partial coherence interferometry preoperatively, at 1 week, 1 month, and >3 months after surgery. MAIN OUTCOME MEASURES Axial length and intraocular pressure were compared at preoperative and postoperative visits. Postoperative intraocular pressure (IOP) was categorised as hypotonous (0-4 mm Hg), low (5-9), normal (10-17), and high (18 or more). RESULTS There was a statistically significant reduction in IOP after 3 months of -12.8 (SD 1.5) mm Hg following trabeculectomy (p<0.001), and -10.7 (1.9) mm Hg after GDD (p<0.001). There was a statistically significant reduction in AL, which was similar after trabeculectomy and GDD at all time points (p<0.001), of -0.15 (0.03) and -0.21 (0.04) mm (1 week), -0.18 (0.02) and -0.10 (0.02) mm (1 month), and -0.16 (0.03) and -0.15 (0.03) mm (3 months). At 3 months or later the AL reduction was related to postoperative IOP and to the amount of IOP reduction (p<0.05, stepwise multiple regression). 10.2% (4/39) of trabeculectomy patients had hypotony after 3 months, with a mean AL reduction (-0.39 (0.11)) that was statistically significantly lower (p<0.01) than the other trabeculectomy eyes (-0.14 (0.15)). CONCLUSIONS There is a small but statistically significant decrease in AL after both trabeculectomy and GDD surgery, greater in eyes that are hypotonous after surgery. The authors suggest that AL reduction can be predicted after 3 months by the formula: AL reduction (mm) = -199+0.006 x IOP reduction+0.008 x final IOP.

Abstract
PURPOSE To compare the efficacy of non-penetrating deep sclerectomy without implant with Crozafon-De Laage punch trabeculectomy, and to evaluate the effect of simultaneous temporal approach phacoemulsification on both techniques. PATIENTS AND METHODS SETTING Department of Ophthalmology of the University of Palermo. DESIGN Prospective randomized clinical trial. Patients and intervention procedures: Sixty-five patients (65 eyes) with primary open angle glaucoma (POAG) or pseudoexfoliative glaucoma (PEXG): 32 eyes underwent non-penetrating deep sclerectomy (NPDS), 17 as single procedure and 15 combined with phacoemulsification (phaco-NPDS), and 33 eyes underwent punch trabeculectomy (PT), 18 single and 15 with phaco (phaco-PT). The patients were randomly assigned to each procedure. No adjuvants, such as Nd: YAG laser goniopuncture, laser suturelysis, and antimetabolites were used. MAIN OUTCOME MEASURES Postoperative complications, number of antiglaucoma medications, and IOP level were checked at each control. Complete success indicated the achievement of the target IOP without antiglaucoma medications, while qualified success indicated the same goal with or without medications. These categories were assessed at two target IOP levels, namely < or =21 mm Hg and < or =17 mm Hg in all four groups. RESULTS The mean follow-up period was 22.5 +/- 2.5 months. The mean preoperative IOP was 30.2 mm Hg in NPDS eyes, 26.8 in phaco-NPDS eyes, 32.1 in PT eyes, and 27.0 in phaco-PT ones, without significant intergroup difference. At the end point the mean IOP was 17.7 +/- 0.8, 15.7 +/- 0.9, 14.2 +/- 1.1, and 13.8 +/- 1.1 mm Hg respectively with postoperative IOP significantly lower (P = 0.005) than preoperative IOP in all groups. No difference was observed among groups at any observation time when simple and combined surgery were compared. Significant difference at the end point was found between NPDS and PT (P = 0.030). As for complete and qualified success with a < or =21 and < or =17 mm Hg target IOP no significant differences were noticed in all groups. Among postoperative complications, hypotony was significantly more frequent in both PT groups when compared with the NPDS groups. The same was true, but relating only to the single procedures, for shallow anterior chamber and choroidal detachment. The Kaplan-Meier cumulative survival curves relating to the qualified success rate in the four surgical groups for a < or =21 mm Hg target IOP (log rank, P = 0.564) and for a < or =17 mm Hg target IOP (log rank, P = 0.591) showed no significant intergroup differences. When the < or =21 mm Hg target IOP was considered, a mild positive trend in combined procedures (both phaco-NPDS and phaco-PT) was found in comparison with simple procedures. At lower IOP target (ie, < or =17 mm Hg) a better trend was found in favor of simple or combined PT procedure. CONCLUSIONS Both techniques, NPDS and PT, without enhancements (ie, implants or antimetabolites) control IOP efficaciously at our end point. Phacoemulsification combined with penetrating and non-penetrating procedures does not seem to interfere with final results. When a lower target IOP and probability of success over time are considered, PT, single or combined, exhibits a better trend. PT, therefore, could be more suitable for higher IOP levels or longer life expectancies.

Abstract
PURPOSE OF REVIEW In the elderly population, the combined presence of cataract and glaucoma is a frequent condition. In this situation, several surgical options are possible: cataract surgery only and later maybe trabeculectomy, trabeculectomy only and later maybe cataract surgery, or combined cataract and glaucoma surgery. This review compares the different surgical options on the basis of their achievable postoperative intraocular pressure (IOP) level and success and complication rates. RECENT FINDINGS The impression of better IOP regulation with trabeculectomy than with phacotrabeculectomy has been recently confirmed by an evidence-based review. Contrary to this finding, the success of deep sclerectomy or trabeculotomy does not seem to be compromised by simultaneous phacoemulsification. In eyes with previous glaucoma-filtering surgery, cataract surgery with clear corneal incision has no effect on mean IOP but increases the 3-year failure probability. For phacotrabeculectomy, moderate evidence of a beneficial effect of MMC on IOP regulation and only weak evidence for separating the incisions has been recently reported by another evidence-based review. SUMMARY The choice of the preferred surgical method depends on the target pressure, the amount of glaucomatous damage, and the grade of visual disturbance caused by the cataract. Phacotrabeculectomy combined with mitomycin C achieves the best IOP lowering of all types of combined cataract and glaucoma surgery currently possible but is associated with potentially sight-threatening complications. In the absence of a low target pressure, phacotrabeculotomy or the combination of phacoemulsification with viscocanalostomy or deep sclerectomy may be the therapy of choice.

Abstract
PURPOSE To determine the efficacy of brimonidine tartrate 0.2% drops given 2 times a day in reducing intraocular pressure (IOP) spikes during the first 24 hours after phacoemulsification cataract surgery. SETTING Department of Ophthalmology, General Hospital of Patras Agios Andreas, Patras, Greece. METHODS In this prospective double-blind placebo-controlled study, 1 eye of 40 consecutive normotensive cataract patients having small-incision cataract surgery was randomized into 1 of 2 treatment arms. Twenty patients received a placebo (artificial tears) and 20 patients received brimonidine tartrate 0.2% drops 2 times a day the day before and the day of surgery. Diurnal IOP variation was the primary efficacy variable; IOP was measured at baseline, before surgery, and 4, 6, 12, and 24 hours postoperatively. RESULTS The placebo group had higher IOPs at every time point after surgery. Peak elevation of IOP occurred 6 hours after surgery. The mean IOP in the placebo group (27.71 mm Hg +/- 3.75 [SD]) was statistically significantly higher than in the brimonidine group (21.45 +/- 1.32 mm Hg) (P<.001). A major IOP rise (>/=20 mm Hg above baseline IOP) occurred in 1 patient (5%) in the placebo group who required emergency hypotensive therapy. Twenty-four hours after surgery, 11 eyes (55%) in the brimonidine group and 4 eyes (20%) in the placebo group had an IOP lower than baseline. CONCLUSION Prophylactic treatment with brimonidine tartrate 0.2% 2 times a day for 2 days was effective in reducing IOP peaks throughout the first 24 hours after phacoemulsification surgery.
