“…Preoperatively, the ocular indexes of the two groups of patients were compared (P > 0.05), and at 6 weeks postoperatively and 12 weeks postoperatively, the naked-eye visual acuity, BCVA, and anterior chamber depth of the patients in the observation group were better than those of the control group (P < 0.05), and the intraocular pressures of the patients in the two groups were compared (P > 0.05), as shown in Table 2. Preoperatively, the CECs, central corneal thickness, and ocular surface disease index were compared between the two groups (P > 0.05), and at 6 weeks postoperatively and 12 weeks postoperatively, the CECs, central corneal thickness, and ocular surface disease index of patients in the observation group were superior to those of the control group (P < 0.05), as shown in Table 3 [18].…”

Cataract is a common ophthalmic disease among the elderly population, which significantly affects their visual acuity. Therefore, effective measures need to be taken to treat cataracts, eliminate symptoms, and improve visual acuity. Traditional clinical approaches usually involve phacoemulsification, which yields moderate results. Thus, more effective treatment options are required to improve ocular indicators, corneal endothelial cell function, inflammatory markers in tears, and prevent complications. In this study, we compared the therapeutic effects and safety of femtosecond laser-assisted cataract surgery with traditional phacoemulsification in cataract patients. The results indicated that femtosecond laser-assisted surgery yielded superior overall treatment outcomes and higher safety levels compared to traditional phacoemulsification. Therefore, implementing femtosecond laser surgery in cataract treatment can achieve the desired therapeutic results without significant complications, leading to significant improvements in patients' visual acuity.

“…Phacoemulsification machines have evolved to include a torsional ultrasound delivery system or femtosecond laser to deliver ultrasound energy efficiently or decrease the total ultrasound energy [13][14][15]. Another recent advancement has been the switch to dual-linear foot-pedal control (Stellaris Elite ® , Bausch+Lomb, St. Louis, MO, USA).…”

Background: The aim of this study was to compare early clinical results regarding the safety and efficacy of dual-linear vs. conventional foot-pedal control in cataract surgery. Methods: This was a paired-eye contralateral, retrospective, observational study. Each patient underwent cataract surgery in both eyes: one eye with dual-linear foot-pedal control (study group) and the other eye with conventional foot-pedal control (control group). Absolute phaco time (APT), average phaco power, effective phaco time (EPT), and surgical complications were analyzed and compared. Corneal endothelial cell count, corneal thickness, corneal volume, and best-corrected distance visual acuity (BCDVA) were measured preoperatively and at 1 week, 1 month, and 3 months postoperatively. Results: A total of 94 patients (188 eyes) were enrolled. The respective APT, average phaco power, and EPT values were 7.05 ± 5.31 s, 28.4 ± 1.00, and 2.05 ± 1.56 s in the study group and 6.82 ± 6.48 s, 18.9 ± 1.74, and 1.35 ± 1.35 s in the control group. Conclusions: The average phaco power and EPT values were significantly higher in the study group. The safety of the dual-linear foot pedal was comparable to that of a conventional pedal in terms of endothelial cell loss, central corneal thickness, and surgical complications.

“…The application of femtosecond laser-assisted cataract surgery (FLACS) provides precise, clear corneal incisions (CCIs), accurate anterior capsulotomy, efficient nuclear fragmentation and reduction of corneal endothelial cell loss. [1][2][3] This technique has the potential to improve surgical outcomes and enable inexperienced surgeons to perform more predictable and reproducible cataract surgery. [4][5][6] Several studies have shown the notable benefits of this technology, including the increased precision of anterior capsulotomies, less intraocular lens (IOL) tilt and decentration, and substantial reductions in ultrasound power and effective phacoemulsification time (EPT).…”

AimsTo assess the safety of femtosecond laser-assisted cataract surgery (FLACS) based on surgical parameters and intraoperative complications analysis and to determine the length of the learning curve for FLACS.MethodsA prospective consecutive cohort study was conducted on Chinese patients who underwent either FLACS (3289 cases) or contemporaneous conventional phacoemulsification cataract surgery (2130 cases). The laser group was divided into four subgroups in chronological order. We recorded intraoperative complication incidences and compared with surgical parameters between groups. Subgroup analysis was conducted to explore the learning curve of FLACS.ResultsThe laser group had a 4.93% incidence of incomplete capsulotomies and a 1.22% incidence of anterior capsule tears. Subgroup analysis showed significant differences in 8 aspects between the first 250 cases (50 cases per surgeon) and the last 2539 cases, but only 2 aspects differed between the second 250 cases (50 cases per surgeon) and the last 2539 cases. There were no significant differences between the third 250 cases (50 cases per surgeon) and the last 2539 cases.ConclusionsThe intraoperative complications of FLACS were reported, and the learning curve is associated with a significant reduction in the incidence of intraoperative complications. The length of the basic learning curve of FLACS is 100 cases, and the length of the advanced learning curve was 150 cases. This study demonstrated that FLACS is characterised by a relatively straightforward and secure operative technique.
