“…Femtosecond laser, a new technology, has been applied in cataract surgery in recent years. Previous studies had reported that femtosecond laser capsulotomy improve the centration, circularity and precision of anterior capsulorrhexis (14,15). The size and shape of the anterior capsulorrhexis greatly affect surgical outcomes, including the position of the lens and the subsequent refractive outcomes.…”

Purpose: To compare the parameters of capsulorrhexis and intraocular lens decentration after femtosecond laser capsulotomy and manual continuous curvilinear capsulorrhexis in high myopic patients with cataracts.Methods: This is a prospective consecutive non-randomized comparative cohort study. Selected patients with axial length > 26.0 mm were divided into femtosecond laser capsulotomy (FS) group and manual continuous curvilinear capsulorrhexis (CCC) group. Five experienced phacoemulsification surgeons conducted all surgeries. Intraoperative complications and post-operative anterior segment photography were recorded. Intraocular lens decentration, area of capsulorrhexis, circularity, and capsule overlap were measured at 1 week, 1 month, and 2 years after surgery. Between group differences of parameters were determined with independent-sample t-test or the Mann–Whitney U-test, analysis of variance test, Pearson chi-square test, and Spearman rank correlation test.Results: The study included 142 eyes (108 patients), 68 eyes in the FS group, and 74 eyes in the CCC group. At 1 week, 1 month, and 2 years after surgery, the area of capsulorrhexis in the CCC group was significantly larger than in the FS group (P < 0.05), while no significant difference was noted in circularity values. The complete overlap ratio in the FS group was significantly higher than that in the CCC group (P < 0.05) at each measured timepoint. Significant correlations were noted between the anterior chamber depth and the area of capsulorrhexis in the CCC group (R = 0.25, P = 0.04), but did not correlate in the FS group (P > 0.05). In patients with an anterior chamber depth >3 mm, the capsule-intraocular lens (IOL) overlap of the CCC group was less than that of the FS group at all measured timepoints after surgery (P < 0.05). Meanwhile, the IOL decentration in the CCC group was significantly greater than that of the FS group in those patients at 2 years after surgery (P < 0.05).Conclusion: In high myopic patients with cataracts, with anterior chamber depth more than 3 mm, femtosecond laser capsulotomy can achieve better capsulorrhexis sizing and centering. Due to more precise capsulotomy and a better capsule-IOL overlap in the FS group, femtosecond laser capsulotomy resulted in better long-term centration of the IOL.

“…However, there are cases of cataracts at birth, and congenital cataracts are mostly influenced by genetic factors, which may be closely related to maternal nutrition deficiency, metabolic disorder, bacterial virus infection during pregnancy, a large amount of harmful radiation, and other factors (2,3). The main symptoms of cataracts are decreased vision, a spot-shaped fixed shadow in the visual field, one eye diplopia or polyopia, refractive changes, visual distortion, and finally color vision changes, resulting in blindness, these symptoms seriously affect the daily life of patients (4). According to reports, the incidence of cataracts is 60-70% during the period of 50-60 years old, and the incidence of cataracts over 70 years old can reach 80%.…”

ObjectiveThis study aimed to discuss the effect of phacoemulsification and intraocular lens implantation (PHACO + IOL) combined with trabeculectomy (TRAB) on cataracts and its influence on the corneal endothelium.MethodsWe selected 120 cataract patients admitted to our hospital from January 2018 to January 2021. According to different surgical methods, they were divided into the control group and the observation group. The observation group was treated with PHACO + IOL combined with TRAB, the control group only received PHACO. The clinical effect, ophthalmic-related parameters, corneal endothelium, complications, the satisfaction of the two groups were observed.ResultsThe total effective rate and total satisfaction rate of the observation group were significantly higher than the control group (P < 0.05). One month after the operation, the vision and central anterior chamber depth of the observation group were higher than those of the control group, and intraocular pressure (IOP) was lower than that of the control group (P < 0.05). One month after the operation, the corneal endothelial cell area and cell density in the observation group were not significantly different from those before operation (P > 0.05). There was no significant difference in the total incidence of complications between the two groups (P > 0.05).ConclusionThis study concluded that PHACO + IOL combined with TRAB has a good curative effect in the treatment of cataracts, which can improve the patients' vision and IOP, keep the functional integrity of corneal endothelial cells, and does not increase the occurrence of complications, the patients' satisfaction is high.
