RESUMEN
This study examined glaucoma patients after undergoing combined cataract and minimally invasive glaucoma surgery (MIGS), microhook ab interno trabeculotomy and goniotomy with the Kahook Dual Blade (KDB), or cataract surgery alone, and it then evaluates their vision-related quality of life (VR-QOL) following the procedure. A total of 75 eyes of 75 consecutive glaucoma patients in this prospective cohort study underwent phacoemulsification (Phaco) or phaco and MIGS (Phaco-TLO) between October 2019 and March 2022. In all cases, the National Eye Institute Visual Function Questionnaire (VFQ-25) was used to evaluate the 20 eyes in the Phaco group and the 55 eyes in the Phaco-TLO group before and at 2 months after surgery. There was a significant increase in the visual acuity (logMAR) at 2 months post-operatively (Phaco group; 0.34 ± 0.10 to -0.07 ± 0.1, p < 0.0001, Phaco-TLO group; 0.37 ± 0.43 to 0.09 ± 0.32, p < 0.0001). The median (25-75th percentile) total VFQ scores in the Phaco group before and at 2 months after surgery were 71.1 (62.4-80.6) and 79.4 (69.0-84.0), respectively. (p = 0.006). The median (25-75th percentile) total VFQ scores in the Phaco-TLO group before and at 2 months after surgery were 69.8 (55.3-78.6) and 74.7 (65.1-83.3), respectively. (p = 0.005). Glaucoma patients who underwent not only cataract surgery alone but also combined cataract surgery and MIGS exhibited significant improvement in the VR-QOL.
RESUMEN
We examined postoperative corneal higher-order aberrations (HOAs) present after combined phacoemulsification with either microhook ab interno trabeculotomy (µLOT-Phaco) or goniotomy, using the Kahook Dual Blade (KDB-Phaco). Retrospective study: A total of 45 eyes underwent µLOT-Phaco and KDB-Phaco (LOT-Phaco) procedures, with 21 eyes that underwent cataract surgery alone used as controls. Visual acuity and corneal HOAs, coma-like aberrations, and spherical-like aberrations were analyzed before and at 1, 2, and 3 months after the surgeries. Risk factors that could potentially influence HOAs were evaluated. No significant postoperative changes were noted for corneal HOAs, coma-like aberrations, and spherical-like aberrations after cataract surgery alone. The mean corneal HOAs, coma-like aberrations, and spherical-like aberrations were 0.222 ± 0.115 µm, 0.203 ± 0.113 µm, and 0.084 ± 0.043 µm at baseline and 0.326 ± 0.195 µm (p < 0.001), 0.302 ± 0.289 µm (p = 0.03), and 0.150 ± 0.115 µm (p < 0.001) at 3 months after LOT-Phaco, respectively. Results of the analysis for risk factors suggested that a longer incision in Schlemm's canal could influence corneal HOAs, coma-like aberrations, and spherical-like aberrations after LOT-Phaco. Although no significant postoperative changes were observed in corneal HOAs and coma-like or spherical-like aberrations after cataract surgery alone, a significant increase in corneal HOAs and coma-like or spherical-like aberrations remained after the LOT-Phaco procedure.
RESUMEN
We compared surgical outcomes in patients with either primary open-angle glaucoma or exfoliation glaucoma after undergoing combined phacoemulsification with either a 120° or 180° incision during a Schlemm's canal microhook ab interno trabeculotomy (µLOT-Phaco). This retrospective comparative case series examined 52 µLOT-Phaco eyes that underwent surgery between September 2017 and December 2020. Surgical qualified success was defined as an intraocular pressure (IOP) of ≤20 mmHg, ≥20% IOP reduction with IOP-lowering medications, and no additional glaucoma surgery. Success rates were evaluated by Kaplan-Meier survival analysis. The number of postoperative IOP-lowering medications and occurrence of complications were also assessed. Mean preoperative IOP in the 120° group was 16.9 ± 7.6 mmHg, which significantly decreased to 10.9 ± 2.7 mmHg (p < 0.01) and 11.1 ± 3.1 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.8 ± 1.4 to 1.4 ± 1.4 (p < 0.01) at 24 months. Mean preoperative IOP in the 180° group was 17.1 ± 7.0 mmHg, which significantly decreased to 12.1 ± 3.2 mmHg (p = 0.02) and 12.9 ± 1.4 mmHg (p = 0.01) at 12 and 24 months, respectively. The mean number of preoperative IOP-lowering medications significantly decreased from 2.9 ± 1.2 to 1.4 ± 1.5 (p < 0.01) at 24 months. The probability of qualified success at 24 months in the 120° and 180° groups was 50.4% and 54.6%, respectively (p = 0.58). There was no difference observed for hyphema formation or IOP spikes. Surgical outcomes were not significantly different between the 120° and 180° incisions in Schlemm's canal.
RESUMEN
PURPOSE: To compare surgical outcomes between patients who underwent Baerveldt glaucoma implantation versus trabeculectomy (TLE) for the treatment of neovascular glaucoma. METHODS: We performed a prospective, randomized, controlled clinical trial at Hiroshima University and Tsukazaki Hospital, Japan. Patients were randomized to Baerveldt glaucoma implantation (23 patients) or TLE (27 patients). The primary outcome measure was the rate of intraocular-pressure control. Secondary outcome measures included complications and interventions. We defined "failure" as intraocular pressure ≥ 22 mmHg or < 20% reduction from baseline pressure, on two consecutive follow-up visits; need for additional glaucoma surgery; vision-threatening complications; or loss of light perception. Kaplan-Meier analysis was used to determine surgical success rates. Postoperative complications and interventions were compared between the two groups with Pearson Chi-square tests. RESULTS: There were no significant differences in demographic or ocular characteristics between the treatment groups at baseline. The postoperative follow-up was 26.6 ± 19.4 months in the Baerveldt group and 27.3 ± 20.1 months in the TLE group. There were no statistical differences (Mann-Whitney nonparametric tests with Bonferroni correction) in postoperative intraocular pressure measured at 6-month intervals. Success rates were 59.1 and 61.6% at 1-year after Baerveldt glaucoma implantation and TLE, respectively. Kaplan-Meier analysis showed no significant difference in success between groups (P = 0.71, log-rank test). Medication use, visual acuity, and interventions were similar between groups. Thirteen late postoperative complications developed in the Baerveldt glaucoma implantation group and four complications developed in the TLE group. Tube exposure was the most common late complication. CONCLUSION: These two procedures produced similar surgical success, intraocular-pressure reductions, visual acuity, and number of medications at the last visit. The TLE group showed smaller numbers of late complications and patients who lost more than two lines of visual acuity. Therefore, TLE might be a safer and better way to treat patients with neovascular glaucoma.

AIM: In patients who underwent multiple intraocular surgeries, we evaluated determinants of decreased corneal endothelial cell density (CECD) after sulcus placement following Ahmed and Baerveldt drainage device surgery. METHODS: We retrospectively reviewed consecutive patients with glaucoma who underwent sulcus placement with an Ahmed glaucoma valve or a Baerveldt glaucoma implant. We compared presurgical and postsurgical CECD and risk factors for decreased CECD. RESULTS: We examined 41 eyes of 41 patients. Postsurgical CECD measurements were assessed 2.0±1.0 times during a median follow-up period of 28 months. The mean intraocular pressure (IOP) decreased from 28.4±11.6 mmHg to 12.2±5.3 mmHg 24 months after the operation. At 24 months, CECD decreased 14.6±5.4% after considering the variability in the number and time points of CECD determinations. History of prior surgery and higher preoperative IOP were significantly associated with a trend for a time-dependent decrease in CECD. CONCLUSIONS: Risk factors for decreased CECD after sulcus placement during Ahmed and Baerveldt drainage device surgery included the number of previous intraocular surgeries and higher presurgical IOP.
