ABSTRACT
AIM: To investigate the clinical efficacy of femtosecond laser-assisted phacoemulsification combined with goniosynechialysis in the treatment of acute angle-closure glaucoma complicated with cataract.METHODS: A total of 53 patients(60 eyes)with primary acute angle closure glaucoma complicated with cataract admitted to our hospital from April 2020 to February 2021 were selected. They were divided into two groups according to the surgical method, with 28 cases(30 eyes)who were treated with femtosecond laser-assisted phacoemulsification combined with goniosynechialysis in group A, and 25 cases(30 eyes)who were treated with traditional cataract phacoemulsification combined with goniosynechialysis in group B. The effective phacoemulsification time(EPT)and cumulative dissipated energy(CDE)during surgery in two groups were recorded. Patients were followed up to 3mo after surgery, and the intraocular pressure, anterior chamber depth(ACD), best corrected visual acuity, corneal endothelial cell loss rate(ECL)and surgical complications were observed in both groups.RESULTS: The postoperative intraocular pressure was significantly decreased and ACD was significantly increased(all P<0.05), and there was no difference between the two groups(all P>0.05). The postoperative best corrected visual acuity of the two groups was significantly better than that before surgery(P<0.05), and group A was significantly better than group B at 1d after surgery(P<0.05). The EPT, CDE, ECL and incidence of complications(7% vs. 27%)in group A were significantly lower than those in group B(all P<0.05).CONCLUSION: Femtosecond laser-assisted cataract phacoemulsification combined with goniosynechialysis in the treatment of primary acute angle-closure glaucoma combined with cataract has a significant therapeutic effect, which can effectively improve surgical safety, reduce the rate of corneal endothelial cell loss, and have fewer complications.
ABSTRACT
@#AIM: To investigate the therapeutic effect of femtosecond laser-assisted cataract surgery(FLACS)in eyes with shallow anterior chamber depth.<p>METHODS: Totally 60 eyes of 55 cataract patients with shallow anterior chamber who received cataract phacoemulsification in Tangshan eye hospital from November 2020 to February 2021 were selected, and divided into two groups according to the surgical methods on patient's subjective willingness: Patients who received FLACS were assigned to the FLACS group(28 patients, 30 eyes), and patients who received conventional Phaco(27 patients, 30 eyes)were assigned to the Phaco group. Preoperative general conditions, cumulative dissipated energy(CDE), effective phacoemulsification time(EPT), postoperative best corrected visual acuity(BCVA), uncorrected visual acuity(UCVA), endothelial cell loss rate(ECL), central macular thickness(CMT)and complications were compared and analyzed.<p>RESULTS:There was no significant difference in preoperative general data between the two groups(<i>P</i>>0.05). In both groups, UCVA at 1d, 1wk and 1mo after surgery and BCVA at 1wk and 1mo after surgery were better than those before surgery, and at 1d after surgery, UCVA in FLACS group was better than that in Phaco group, the difference was statistically significant(<i>P</i><0.05). In the FLACS group, CDE, EPT, ECL at 1wk and 1mo after surgery, and the incidence of corneal edema at 1d and 1wk after surgery were all lower than those in the Phaco group(all <i>P</i><0.05). There was no significant change in CMT in either the intragroup comparison or the intergroup comparison(<i>P</i>>0.05).<p>CONCLUSION:FLACS is safe and effective in patients with shallow anterior chamber cataract, which can significantly reduce the rate of endothelial cell loss, quickly restore vision, reduce the incidence of complications, and has no significant effect on macula.
