Abstract:
Objective To explore the impact of modified capsular polishing technique on visual quality in patients af-ter femtosecond laser-assisted cataract surgery.Methods Eighty-four patients(84 eyes)who visited Xi'an People's Hospital(Xi'an Fourth Hospital)from January to June 2023 and were scheduled to undergo femtosecond laser-assisted phacoemulsification cataract extraction combined with intraocular lens implantation were selected as the research subjects.Before the surgery,the patients were randomly divided into an observation group and a control group.The observation group consisted of 44 patients(44 eyes)who received modified capsular polishing treatment.Viscoelastic material was in-jected behind the iris into the subcapsular space of the anterior capsule,causing compression of the peripheral posterior capsule and elevation of the central posterior capsule,so that parts of the anterior and posterior capsules adhered to each other.A Whitman Shepherd bimanual capsular polisher was then inserted through the main incision to perform a thorough 360-degree polishing of the anterior capsule and equatorial region,while simultaneously polishing the adhered areas of the posterior capsule.The control group consisted of 40 patients(40 eyes)who received traditional irrigation/aspiration(I/A)capsular polishing treatment.There were no statistically significant differences between the two groups in terms of gender composition,age,and preoperative best-corrected visual acuity(all P＞0.05).Both groups of patients were followed up to observe their best-corrected visual acuity,spherical aberration,coma aberration,and trefoil aberration at 1 day,1 week,1 month,and 3 months postoperatively.Results At 1 day,1 week,1 month,and 3 months postoperatively,the best-cor-rected visual acuity of patients in the observation group was superior to that in the control group,with statistically signifi-cant differences between the two groups at each time point(all P＜0.05).At 1 day,1 month,and 3 months postoperative-ly,the spherical aberration in the observation group was significantly lower than that in the control group(all P＜0.05).Three months postoperatively,the median coma aberration in the observation group[0.060(0.034,0.108)]was signifi-cantly lower than that in the control group[0.100(0.070,0.146)],with a statistically significant difference(Z=-2.805,P=0.005).One day postoperatively,the median trefoil aberration in the observation group[0.272(0.159,0.418)]was significantly lower than that in the control group[0.360(0.248,0.449)],with a statistically significant difference(Z=-2.299,P=0.022).Conclusion The modified capsular polishing technique can improve the visual quality of patients in the mid-term period after femtosecond laser-assisted cataract surgery.
