Yao L, Wang H, Wang Y, Zhao P, Bai H. Phacoemulsification combined with goniosynechialysis versus phacoemulsification alone for patients with primary angle‑closure disease: A meta-analysis. PLoS One 2024; 19:e0296849. [PMID: 38306318 PMCID: PMC10836673 DOI: 10.1371/journal.pone.0296849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Accepted: 12/21/2023] [Indexed: 02/04/2024] Open
Abstract
This meta-analysis aims to systematically compare the efficacy between phacoemulsification (PE) combined with goniosynechialysis (GSL) and PE alone for primary angle-closure disease (PACD) patients. All the data were searched from the PubMed, EMBASE and the Cochrane Library. The Cochrane Handbook was used to evaluate the quality of the included studies. Additionally, this meta-analysis was performed by using the Revman 5.4 software. Nine randomized controlled trials (RCTs) were included in this study. Compared with PE alone group, PE+GSL could result significant reduction in the IOP (MD, 1.81; p = 0.002). In the instrumental subgroup, also more reduction of IOP was shown in the PE+GSL group (MD, 2.11; p = 0.02). In the viscogonioplasty (VGP) subgroup, there was not no statistical difference between PE alone group and PE+GSL group (MD, 1.53; p = 0.11). Also, more reduction of peripheral anterior synechiae (PAS) was shown in the PE+GSL group (MD,59.15; p<0.00001). For the change in angle open distance (AOD)500, AOD 750, trabecular-iris space (TISA)500, number of glaucoma medications and best corrected visual acuity (BCVA), there was no difference between two groups (p = 0.25, 0.35, 0.17, 0.56, 0.08). For TISA 750, more improvement was shown in the PE+GSL group (p<0.00001). Instrumental separation had better effect on lowering IOP when it combined with PE. Both instrumental separation and VGP could reduce postoperative PAS. The operation of GSL has no obvious effect on postoperative vision.

Meta-Analysis of Literature. J Clin Med 2024; 13:508. [PMID: 38256642 PMCID: PMC10816145 DOI: 10.3390/jcm13020508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/23/2023] [Accepted: 01/08/2024] [Indexed: 01/24/2024] Open
Abstract
BACKGROUND AND OBJECTIVES This study aimed to evaluate the effect of cataract extraction on intraocular pressure at 6, 12, and 24 months and their difference compared to the baseline in diverse glaucoma subtypes. MATERIALS AND METHODS We carried out research in the MEDLINE, Cochrane Library and EMBASE databases, as of April 2022 for relevant papers, filtered according to established inclusion and exclusion criteria. The meta-analysis evaluated the Mean Reduction and relative Standard Error in these subpopulations at predetermined times. A total of 41 groups (2302 eyes) were included in the systematic review. Due to the significant heterogeneity, they were analysed through a Random Effects Model. RESULTS We obtained these differences from baseline: (1) Open Angle Glaucoma at 6, 12 and 24 months, respectively: -2.44 mmHg, -2.71 mmHg and -3.13 mmHg; (2) Angle Closure Glaucoma at 6, 12 and 24 months, respectively: -6.81 mmHg, -7.03 mmHg and -6.52 mmHg; (3) Pseudoexfoliation Glaucoma at 12 months: -5.30 mmHg; (4) Ocular Hypertension at 24 months: -2.27 mmHg. CONCLUSIONS Despite a certain variability, the reduction in ocular pressure was statistically significant at 6, 12 and 24 months in both Open Angle Glaucoma and Angle Closure Glaucoma, the latter being superior. Data for Pseudoexfoliation Glaucoma and for Ocular Hypertension are available, respectively, only at 12 months and at 24 months, both being significant.

Phacogoniotomy versus phacotrabeculectomy for advanced primary angle-closure glaucoma with cataract: A randomized non-inferiority trial. Asia Pac J Ophthalmol (Phila) 2024; 13:100033. [PMID: 38383075 DOI: 10.1016/j.apjo.2023.100033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 12/16/2023] [Accepted: 12/19/2023] [Indexed: 02/23/2024] Open
Abstract
PURPOSE To investigate the effectiveness and safety of phacogoniotomy versus phacotrabeculectomy (PVP) among patients with advanced primary angle-closure glaucoma (PACG) and cataracts. DESIGN Multicenter, randomized controlled, non-inferiority trial. METHODS A total of 124 patients (124 eyes) with advanced PACG and cataracts were enrolled, with 65 in the phacogoniotomy group and 59 in the phacotrabeculectomy group. Patients were followed up for 12 months with standardized evaluations. The primary outcome was the reduction in intraocular pressure (IOP) from baseline to 12 months postoperatively, of which a non-inferiority margin of 4 mmHg was evaluated. Secondary outcomes included the cumulative surgical success rate, postoperative complications, and changes in the number of glaucoma medications. RESULTS After 12 months, phacogoniotomy demonstrated non-inferiority to phacotrabeculectomy in terms of IOP reduction, with mean IOP reductions of - 26.1 mmHg and - 25.7 mmHg (P = 0.383), respectively, from baseline values of around 40 mmHg. Both groups experienced a significant reduction in the mean number of medications used postoperatively (P < 0.001). The cumulative success rate was comparable between the groups (P = 0.890). However, phacogoniotomy had a lower rate of postoperative complications and interventions (12.3% and 4.6%) compared to phacotrabeculectomy (23.7% and 20.3% respectively). The phacogoniotomy group reported shorter surgery time (22.1 ± 6.5 vs. 38.8 ± 11.1 min; P = 0.030) and higher quality of life (EQ-5D-5 L) improvement at 12 months (7.0 ± 11.5 vs. 3.0 ± 12.9, P = 0.010) than the phacotrabeculectomy group. CONCLUSIONS Phacogoniotomy was non-inferior to phacotrabeculectomy in terms of IOP reduction for advanced PACG and cataracts. Additionally, phacogoniotomy provided a shorter surgical time, lower postoperative complication rate, fewer postoperative interventions, and better postoperative quality of life.

Abstract
BACKGROUND Primary angle-closure glaucoma (PACG) is characterized by a rise in intraocular pressure (IOP) secondary to aqueous outflow obstruction, with relative pupillary block being the most common underlying mechanism. There is increasing evidence that lens extraction may relieve pupillary block and thereby improve IOP control. As such, comparing the effectiveness of lens extraction against other commonly used treatment modalities can help inform the decision-making process. OBJECTIVES To assess the effectiveness of lens extraction compared with other interventions in the treatment of chronic PACG in people without previous acute angle-closure attacks. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, one other database, and two trials registers (December 2019). We also screened the reference lists of included studies and the Science Citation Index database. We had no date or language restrictions. SELECTION CRITERIA We included randomized controlled trials (RCTs) comparing lens extraction with other treatment modalities for chronic PACG. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methodology. MAIN RESULTS We identified eight RCTs with 914 eyes. We obtained data for participants meeting our inclusion criteria for these studies (PACG only, no previous acute angle-closure attacks), resulting in 513 eyes included in this review. The participants were recruited from a diverse range of countries. We were unable to conduct meta-analyses due to different follow-up periods and insufficient data. One study compared phacoemulsification with laser peripheral iridotomy (LPI) as standard care. Participants in the phacoemulsification group were less likely to experience progression of visual field loss (odds ratio [OR] 0.35, 95% confidence interval [CI] 0.13 to 0.91; 216 eyes; moderate certainty evidence), and required fewer IOP-lowering medications (mean difference [MD] -0.70, 95% CI -0.89 to -0.51; 263 eyes; moderate certainty evidence) compared with standard care at 12 months. Moderate certainty evidence also suggested that phacoemulsification improved gonioscopic findings at 12 months or later (MD -84.93, 95% CI -131.25 to -38.61; 106 eyes). There was little to no difference in health-related quality of life measures (MD 0.04, 95% CI -0.16 to 0.24; 254 eyes; moderate certainty evidence), and visual acuity (VA) (MD 2.03 ETDRS letter, 95% CI -0.77 to 4.84; 242 eyes) at 12 months, and no observable difference in mean IOP (MD -0.03mmHg, 95% CI -2.34 to 2.32; 257 eyes; moderate certainty evidence) compared to standard care. Irreversible loss of vision was observed in one participant in the phacoemulsification group, and three participants in standard care at 36 months (moderate-certainty evidence). One study (91 eyes) compared phacoemulsification with phaco-viscogonioplasty (phaco-VGP). Low-certainty evidence suggested that fewer IOP-lowering medications were needed at 12 months with phacoemulsification (MD -0.30, 95% CI -0.55 to -0.05). Low-certainty evidence also suggested that phacoemulsification may have improved gonioscopic findings at 12 months or later compared to phaco-VGP (angle grading MD -0.60, 95% CI -0.91 to -0.29; TISA500 MD -0.03, 95% CI -0.06 to -0.01; TISA750 MD -0.03, 95% CI -0.06 to -0.01; 91 eyes). Phacoemulsification may result in little to no difference in best corrected VA at 12 months (MD -0.01 log MAR units, 95% CI -0.10 to 0.08; low certainty evidence), and the evidence is very uncertain about its effect on IOP at 12 months (MD 0.50 mmHg, 95% CI -2.64 to 3.64; very low certainty evidence). Postoperative fibrin reaction was observed in two participants in the phacoemulsification group and four in the phaco-VGP group. Three participants in the phaco-VGP group experienced hyphema. No data were available for progression of visual field loss and quality of life measurements at 12 months. Two studies compared phacoemulsification with phaco-goniosynechialysis (phaco-GSL). Low-certainty evidence suggested that there may be little to no difference in mean IOP at 12 months (MD -0.12 mmHg, 95% CI -4.72 to 4.48; 1 study, 32 eyes) between the interventions. Phacoemulsification did not reduce the number of IOP-lowering medications compared to phaco-GSL at 12 months (MD -0.38, 95% CI -1.23 to 0.47; 1 study, 32 eyes; moderate certainty evidence). Three eyes in the phaco-GSL group developed hyphemas. No data were available at 12 months for progression of visual field loss, gonioscopic findings, visual acuity, and quality of life measures. Three studies compared phacoemulsification with combined phaco-trabeculectomy, but the data were only available for one study (63 eyes). In this study, low-certainty evidence suggested that there was little to no difference between groups in mean change in IOP from baseline (MD -0.60 mmHg, 95% CI -1.99 to 0.79), number of IOP-lowering medications at 12 months (MD 0.00, 95% CI -0.42 to 0.42), and VA measured by the Snellen chart (MD -0.03, 95% CI -0.18 to 0.12). Participants in the phacoemulsification group had fewer complications (risk ratio [RR] 0.59, 95% CI 0.34 to 1.04), and the phaco-trabeculectomy group required more IOP-lowering procedures (RR 5.81, 95% CI 1.41 to 23.88), but the evidence was very uncertain. No data were available for other outcomes. AUTHORS' CONCLUSIONS Moderate certainty evidence showed that lens extraction has an advantage over LPI in treating chronic PACG with clear crystalline lenses over three years of follow-up; ultimately, the decision for intervention should be part of a shared decision-making process between the clinician and the patient. For people with chronic PACG and visually significant cataracts, low certainty evidence suggested that combining phacoemulsification with either viscogonioplasty or goniosynechialysis does not confer any additional benefit over phacoemulsification alone. There was insufficient evidence to draw any meaningful conclusions regarding phacoemulsification versus trabeculectomy. Low certainty evidence suggested that combining phacoemulsification with trabeculectomy does not confer any additional benefit over phacoemulsification alone, and may cause more complications instead. These conclusions only apply to short- to medium-term outcomes; studies with longer follow-up periods can help assess whether these effects persist in the long term.

Abstract
BACKGROUND The aim of this meta-analysis is to compare the efficacy and safety of combined phacoemulsification (Phaco) with goniosynechialysis (GSL) to either Phaco or to Phaco combined with trabeculectomy or trabeculectomy alone in patients with angle closure glaucoma (ACG). METHODS Five main electronic databases were searched for the eligible studies. Intraocular pressure (IOP) decrease was set as the primary outcome, while anti-glaucomatous medication decrease, changes of anterior chamber depth (ACD), range of peripheral anterior synechia (PAS), and complication occurrence were the secondary outcomes. Standard mean difference (SMD) and relative risk (RR) were the size effects for continuous and binomial data, respectively. Either fixed-effects model or random-effects model was chosen to pool the data based on the heterogeneities. RESULTS A total of 7 eligible studies were included. The combined data showed the IOP decreased more significantly after Phaco-GSL than that after Phaco alone (SMD = -0.42,95%CI: -0.70 - 0.14, I = 17.6%, Z = 2.90, P = .004). However, there were no distinct differences regarding medication decrease (SMD = -0.25,95%CI: -0.70 - 0.21, I = 0%, Z = 1.06, P = 0.29), ACD, the range of PAS and complication occurrence rate when compared Phaco-GSL to Phaco. Moreover, Phaco-GSL was comparable to Phaco-trabeculectomy/trabeculectomy in decreasing IOP (SMD = -0.08, 95%CI = -0.32 - 0.15, I = 0%, Z = 0.70, P = .49). CONCLUSIONS Phaco-GSL might be an optimal procedure to treat ACG with concomitant cataract due to its bleb-less nature, and its capacity for lowering IOP seems superior to Phaco alone and comparable to Phaco-trabeculectomy/trabeculectomy.

Abstract
Importance The effectiveness of intraocular pressure (IOP) lowering phacoemulsification combined with goniosynechialysis (GSL) compared with phacoemulsification without GSL remains unknown. Objective To compare the IOP outcome after 1 year in patients with synechial primary angle-closure disease (PACD) and cataract who underwent phacoemulsification with intraocular lens implantation (PEI) alone compared with PEI with GSL (PEI-GSL). Design, Setting, and Participants A multicenter randomized clinical trial was conducted from September 29, 2011, to March 16, 2015; data analysis was performed from April 1, 2015, to March 4, 2019. Patients with PACD, defined as primary angle closure or primary angle-closure glaucoma, and at least 90° peripheral anterior synechiae (PAS) with cataract were included. Patients were randomized to undergo PEI alone or PEI-GSL. Patients were followed up for 1 year with standardized evaluations. Intention-to-treat analysis was performed. Interventions Phacoemulsification with intraocular lens implantation alone or with GSL. Main Outcomes and Measures Successful control of IOP at 12 months, defined as IOP 21 mm Hg or lower without use of topical IOP-lowering medications and a decrease in IOP of 20% or more from baseline IOP. Results Data from 78 patients (78 eyes) were analyzed. Of these, 37 patients were Chinese (47.4%) and 54 were women (69.2%); mean (SD) age was 67.7 (8.9) years. Mean deviation (SD) at baseline was -13.5 dB (9.4 dB). Forty patients were randomized to the PEI group and 38 to the PEI-GSL group. The mean (SD) IOP at baseline was 22.3 (8.5) mm Hg for the PEI group and 22.9 (5.3) mm Hg for the PEI-GSL group. At 1 year, the mean IOP was 14.3 (5.0) mm Hg for the PEI group and 15.9 (4.5) mm Hg for the PEI-GSL group. Successful control at 1 year occurred in 21 patients (52.5%) in the PEI group and 22 patients (57.9%) in the PEI-GSL group (mean difference, 5.4%; 95% CI, -18.0% to 28.2%; P = .63). In eyes that achieved successful control, mean IOP at 1 year was 12.5 (2.7) mm Hg (range, 7.0-19.0) for the PEI group and 13.6 (2.4) mm Hg (range, 9.0-18.0) for the PEI-GSL group. The number of medications at baseline and 1 year decreased from a mean of 2.2 (0.8) to 0.5 (0.9) in the PEI group and 1.9 (0.9) to 0.6 (1.2) in the PEI-GSL group (P < .001 for each), with a mean change difference of 0.4% (95% CI, -0.02% to 0.9%; P = .06). There were 3 postoperative complications (7.5%) in the PEI group and 3 (7.9%) in the PEI-GSL group. These included IOP spike (IOP≥30 mm Hg) (n = 3), excessive anterior chamber inflammation (n = 1), and posterior capsule opacification (n = 2). Conclusions and Relevance This randomized clinical trial was unable to show that PEI-GSL added additional IOP lowering compared with PEI alone in patients with PACD. Trial Registration ClinicalTrials.gov identifier: NCT02376725.

KOREAN JOURNAL OF OPHTHALMOLOGY 2019; 33:303-314. [PMID: 31389206 PMCID: PMC6685830 DOI: 10.3341/kjo.2018.0135] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 02/27/2019] [Accepted: 03/05/2019] [Indexed: 11/23/2022] Open
Abstract
Purpose To compare the effects of cataract surgery on intraocular pressure (IOP) according to preoperative factor in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Methods The medical records of 75 POAG and 95 PACG patients who underwent cataract surgery were reviewed. We classified POAG patients with a preoperative peak IOP of less than 31 mmHg and less than three medications used before surgery and PACG patients with a peak IOP of less than 42 mmHg, less than three medications used, and peripheral anterior synechiae of less than four clock hours into group 1. Patients with levels exceeding these thresholds were classified into group 2. The IOP, numbers of medications, and success rates were compared between two groups. Results At 36 months after surgery, IOP reduction in group 1 was significantly greater than that in group 2 among POAG patients (−1.7 ± 2.1 vs. −0.6 ± 2.0 mmHg, p = 0.021); however, there was no significant difference between the two groups for PACG patients (−2.5 ± 2.0 vs. −2.2 ± 3.3 mmHg, p = 0.755). The medication changes were similar between the two groups for both POAG and PACG patients. The success rate at 36 months was significantly higher in group 1 than in group 2 for POAG patients (66.7% vs. 35.7%, p = 0.009), but there was no significant difference between the two groups for PACG patients (79.1% vs. 69.2%, p = 0.264). Conclusions For patients with relatively low peak IOP who used fewer medications before surgery, cataract surgery alone was effective for IOP control in both POAG and PACG patients. Conversely, For POAG patients with a history of higher peak IOP and who used more medications, cataract surgery was not effective in lowering IOP, whereas it resulted in relatively good IOP values in PACG patients.

Abstract
PURPOSE For patients with comorbid cataract and primary open-angle glaucoma (POAG), guidance is lacking as to whether cataract extraction and traditional filtering surgery should be performed as a staged or combined procedure. Achieving this guidance requires an evidence-based understanding of the effects of phacoemulsification alone on intraocular pressure (IOP) in patients with POAG. For this reason, a systematic review and meta-analysis was undertaken to synthesize evidence quantifying the effect of phacoemulsification on IOP and the required number of topical glaucoma medications in patients with cataract and POAG. MATERIALS AND METHODS Database searches were last run on August 15, 2016 to identify potentially relevant studies. Identified articles were screened for relevance and meta-analysis was used to compute postoperative mean and percentage reduction in IOP (IOPR%) as well as mean difference in topical glaucoma medications. RESULTS The search strategy identified 1613 records. Thirty-two studies (1826 subjects) were included in quantitative synthesis. A 12%, 14%, 15%, and 9% reduction in IOP from baseline occurred 6, 12, 24, and 36 months after phacoemulsification. A mean reduction of 0.57, 0.47, 0.38, and 0.16 medications per patient of glaucoma medication occurred 6, 12, 24, and 36 months after phacoemulsification. CONCLUSIONS Phacoemulsification as a solo procedure does lower IOP in patients with POAG, and reduces dependency on topical glaucoma medications. These effects appear to last at least 36 months with gradual loss of the initial effect noted after 2 years. Certain populations appear to experience much greater reductions in IOP than others and future work to identify these high responding patients is needed.

Abstract
PURPOSE To assess the effects of phacoemulsification, intraocular lens implantation, and goniosynechialysis on patients with primary angle-closure glaucoma and cataract. METHODS A total of 145 eyes of 133 consecutively recruited patients were randomly divided into Phaco group and Trab group. Ocular parameters were measured before and after surgery. RESULTS The mean follow-up period was 13.2±5.6 months. The visual acuity in the Phaco group was significantly improved, whereas no alternation was found in the Trab group after surgery. The intraocular pressure (IOP) had no notable difference in 2 groups before surgery. Compared with preoperative IOP, there was significant decrease after surgery. No remarkable change in the IOP was measured in the 2 groups after surgery for 12 months. The anterior chamber depth was markedly augmented in the Phaco group compared with the Trab group after surgery for 3 months. Compared with the the Trab group, no obvious change in coefficient of outflow facility was found in the Phaco group before and after surgery, whereas there was a significant increase relative to its preoperation. The angle closure decreased from (290±25) to (60±35) degrees after surgery for 12 months in the Phaco group and no significant alteration was observed in the Trab group. The reduction extent of peripheral anterior synechiae was in direct proportion to the decreasing level of angle closure in the 2 groups. The change in the corneal endothelial cell density had no significant difference between 2 groups before and after surgery. CONCLUSIONS The treatment of phacoemulsification, intraocular lens implantation, and goniosynechialysis is safe and effective for patients with primary angle-closure glaucoma and cataract.

Abstract
AIM To compare the effectiveness of brimonidine/timolol fixed combination (BTFC) and dorzolamide/timolol fixed combination (DTFC) in the management of short-term intraocular pressure (IOP) increase after phacoemulsification surgery. METHODS Eighty eyes of 80 patients undergoing phacoemulsification and intraocular lens (IOL) implantation were randomly assigned into three groups. Group 1 consisted of 28 eyes and represented the control group. Group 2 consisted of 25 eyes undergoing phacoemulsification surgery and BTFC was instilled at the end of surgery. Group 3 consisted of 27 eyes undergoing phacoemulsification surgery and DTFC was instilled at the end of surgery. IOP was measured preoperatively and 6, 24h and 1wk postoperatively. RESULTS There was no statistically significant difference in preoperative baseline IOP among the three groups (P=0.84). However, IOP was significantly lower in groups 2 and 3 compared to the control group (P<0.05 for all comparisons) at all postoperative visits. There was no significant difference between groups 2 and 3 at any visit. Eight eyes (28.6%) in the control group, two (8%) in Group 2 and one (3.7%) in Group 3 had IOP >25 mm Hg at 6h after surgery (P=0.008). However, IOP decreased and was >25 mm Hg in only one eye in each group at 24h after surgery. CONCLUSION BTFC and DTFC have similar effects in reducing increases in IOP after phacoemulsification surgery and can both be recommended for preventing IOP spikes after such surgery.

Abstract
BACKGROUND Cataract and glaucoma are leading causes of blindness worldwide, and their co-existence is common in elderly people. Glaucoma surgery can accelerate cataract progression, and performing both surgeries may increase the rate of postoperative complications and compromise the success of either surgery. However, cataract surgery may independently lower intraocular pressure (IOP), which may allow for greater IOP control among patients with co-existing cataract and glaucoma. The decision between undergoing combined glaucoma and cataract surgery versus cataract surgery alone is complex. Therefore, it is important to compare the effectiveness of these two interventions to aid clinicians and patients in choosing the better treatment approach. OBJECTIVES To assess the relative effectiveness and safety of combined surgery versus cataract surgery (phacoemulsification) alone for co-existing cataract and glaucoma. The secondary objectives include cost analyses for different surgical techniques for co-existing cataract and glaucoma. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2014, Issue 10), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2014), EMBASE (January 1980 to October 2014), PubMed (January 1948 to October 2014), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to October 2014), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 3 October 2014.We checked the reference lists of the included trials to identify further relevant trials. We used the Science Citation Index to search for references to publications that cited the studies included in the review. We also contacted investigators and experts in the field to identify additional trials. SELECTION CRITERIA We included randomized controlled trials (RCTs) of participants who had open-angle, pseudoexfoliative, or pigmentary glaucoma and age-related cataract. The comparison of interest was combined cataract surgery (phacoemulsification) and any type of glaucoma surgery versus cataract surgery (phacoemulsification) alone. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility, collected data, and judged risk of bias for included studies. We used standard methodological procedures expected by the Cochrane Collaboration. MAIN RESULTS We included nine RCTs, with a total of 655 participants (657 eyes), and follow-up periods ranging from 12 to 30 months. Seven trials were conducted in Europe, one in Canada and South Africa, and one in the United States. We graded the overall quality of the evidence as low due to observed inconsistency in study results, imprecision in effect estimates, and risks of bias in the included studies.Glaucoma surgery type varied among the studies: three studies used trabeculectomy, three studies used iStent® implants, one study used trabeculotomy, and two studies used trabecular aspiration. All of these studies found a statistically significant greater decrease in mean IOP postoperatively in the combined surgery group compared with cataract surgery alone; the mean difference (MD) was -1.62 mmHg (95% confidence interval (CI) -2.61 to -0.64; 489 eyes) among six studies with data at one year follow-up. No study reported the proportion of participants with a reduction in the number of medications used after surgery, but two studies found the mean number of medications used postoperatively at one year was about one less in the combined surgery group than the cataract surgery alone group (MD -0.69, 95% CI -1.28 to -0.10; 301 eyes). Five studies showed that participants in the combined surgery group were about 50% less likely compared with the cataract surgery alone group to use one or more IOP-lowering medications one year postoperatively (risk ratio (RR) 0.47, 95% CI 0.28 to 0.80; 453 eyes). None of the studies reported the mean change in visual acuity or visual fields. However, six studies reported no significant differences in visual acuity and two studies reported no significant differences in visual fields between the two intervention groups postoperatively (data not analyzable). The effect of combined surgery versus cataract surgery alone on the need for reoperation to control IOP at one year was uncertain (RR 1.13, 95% CI 0.15 to 8.25; 382 eyes). Also uncertain was whether eyes in the combined surgery group required more interventions for surgical complications than those in the cataract surgery alone group (RR 1.06, 95% CI 0.34 to 3.35; 382 eyes). No study reported any vision-related quality of life data or cost outcome. Complications were reported at 12 months (two studies), 12 to 18 months (one study), and two years (four studies) after surgery. Due to the small number of events reported across studies and treatment groups, the difference between groups was uncertain for all reported adverse events. AUTHORS' CONCLUSIONS There is low quality evidence that combined cataract and glaucoma surgery may result in better IOP control at one year compared with cataract surgery alone. The evidence was uncertain in terms of complications from the surgeries. Furthermore, this Cochrane review has highlighted the lack of data regarding important measures of the patient experience, such as visual field tests, quality of life measurements, and economic outcomes after surgery, and long-term outcomes (five years or more). Additional high-quality RCTs measuring clinically meaningful and patient-important outcomes are required to provide evidence to support treatment recommendations.
