Efficacy and safety of dropless cataract surgery.

ABSTRACT: Purpose:To evaluate the clinical outcome following intraoperative transzonular intravitreal injection of triamcinolone acetonide and moxifloxacin in patients undergoing phacoemulsification cataract extraction with intraocular lens (IOL) implantation. Methods:In this prospective, non-randomized, clinical, interventional study, a total of 200 eyes were enrolled. Patients who voluntarily gave their consent after being informed about dropless cataract surgery along with its pros and cons were included. Those who had glaucoma or were known steroid responders as well as those who were lost to follow-up were excluded. 0.1 ml each of moxifloxacin (500 mg) and triamcinolone acetonide (4 mg) were injected transzonularly following IOL implantation in phacoemulsification cataract surgery with the help of 27G curved cannula. Slit-lamp examination was done to detect cells, visual acuity was noted, and intraocular pressure was measured postoperatively on day 1, 7, 30, 60, and 90. Results:Uncorrected visual acuity (UCVA) greater than 6/9 was achieved in 96% of patients at the end of 3 months. The mean IOP was found to be normal in all the cases at every visit. Twenty patients complained of floaters on postoperative day 1 (D1), which decreased to zero after 60 days (D60). None of the patients needed any eye drop during the entire postoperative period. Conclusion:The study demonstrates that this procedure is advantageous and safe.

Project description:PurposeTo compare the efficiency, efficacy, and safety, as well as the educational value, of heads-up (three-dimensional visualization system-assisted) and traditional microscopic cataract surgery.MethodsThis randomized noninferiority trial enrolled 242 eyes of 201 patients who received femtosecond laser-assisted cataract surgery. The questionnaire study enrolled 26 medical interns and 39 medical students. Patients received surgery under either a three-dimensional visualization system (3D group, 117 eyes) or traditional microscope (TM group, 125 eyes) after random allocation. The primary outcome was surgical time. The noninferiority margin of surgical time was 60 seconds. Secondary outcomes included ultrasound power, phacoemulsification time, visual acuity, intraocular pressure, endothelial cell density, central corneal thickness, complications, and observer satisfaction scores for surgical procedures.ResultsSurgical time was 462.03 ± 80.36 seconds in the 3D group and 452.13 ± 76.63 seconds in the TM group (difference 9.90 seconds; 95% CI, -9.98 to 29.78; P = 0.365). Visual acuity and other perioperative parameters were comparable between the 3D group and the TM group (all P > 0.05). Incidences of both intraoperative and postoperative complications were low and not statistically different between groups (all P > 0.05). Across all observers, 3D surgery was superior to TM surgery for improving the degree of satisfaction (all P < 0.001).ConclusionsThe surgical efficiency of heads-up cataract surgery is not inferior to traditional microscopic surgery. Both methods achieved similar efficacy and safety outcomes. Moreover, heads-up cataract surgery showed a significant advantage in medical education.Translational relevanceOur findings show that heads-up cataract surgery has comparable efficiency, efficacy, and safety, as well as superior medical educational value, to TM surgery, which lays the foundation for promoting and popularizing this technology.

Project description:BackgroundCataract surgery in diabetics is more technically challenging due to a number of factors including poor intraoperative pupil dilation and a higher risk of vision threatening complications. This study evaluates the safety and efficacy of an intracameral combination of 2 mydriatics and 1 anesthetic (ICMA, Mydrane) for cataract surgery in patients with well-controlled type-2 diabetes.MethodsPost-hoc subgroup analysis of a phase 3 randomized study, comparing ICMA to a conventional topical regimen. Data were collected from 68 centers in Europe and Algeria. Only well-controlled type-2 diabetics, free of pre-proliferative retinopathy, were included. The results for non-diabetics are also reported. The primary efficacy variable was successful capsulorhexis without additional mydriatic treatment. Postoperative safety included adverse events, endothelial cell density and vision.ResultsAmong 591 randomized patients, 57 (9.6%) had controlled type 2 diabetes [24 (42.1%) in the ICMA Group and 33 (57.9%) in the Topical Group; intention-to-treat (ITT) set]. Among diabetics, capsulorhexis was successfully performed without additional mydriatics in 24 (96.0%; modified-ITT set) patients in the ICMA Group and 26 (89.7%) in the Topical Group. These proportions were similar in non-diabetics. No diabetic patient [1 (0.5%) non-diabetics] in the ICMA Group had a significant decrease in pupil size (≥3 mm) intraoperatively compared to 4 (16.0%; modified-ITT set) diabetics [16 (7.3%) non-diabetics] in the Topical group. Ocular AE among diabetics occurred in 2 (8.0%; Safety set) patients in the ICMA Group and 5 (16.7%) in the Topical Group. Endothelial cell density at 1 month postoperatively was similar between groups in diabetics (P = 0.627) and non-diabetics (P = 0.368).ConclusionsICMA is effective and can be safely used in patients with well-controlled diabetes, with potential advantages compared to a topical regimen including reduced systemic risk, better corneal integrity and reduced risk of ocular complications.Trial registrationThe trial was registered at (reference # NCT02101359) on April 2, 2014.
