Clinical Analysis Of Femtosecond Laser-assisted Cataract Surgery

Objective:To study the efficacy, safety, practicality and complications offemtosecond laser-assisted cataract surgery.Method:A prospective cohort study of all patients (n=40,age>18) whoaccept cataract surgery in Xiamen University Eye Hospital during January2014to March2014were randomly divided into2groups:FLACS andPCS,20eyes in each group.The aim of this project is to compare theCumulative dissipated energy(CDE)、 Effective phacoemulsificationtime(EPT)、balanced salt solution volume、intraocular pressure(IOP)、Bestcorrected visual acuity(BCVA) after surgery、Corneal endothelial cell loss、Postoperative Aqueous flare and complication.The data were comparedstatistically using t-test and X2-test．Result:There was no statistically significant difference in Sex, age, eye,cataract grade, corneal endothelial cell before surgery,BCVA betweenFLACS group and PCS group.Comparing with the PCS group,the CDE、EPTand Estimated fluid used of the FLACS group has fallen by49.6%,46.8%and22.5%.There was a significant correlation between CDE、EPT、balancedsalt solution volume and postoperative aqueous flare(r=0.395,0.453,0.376;P<0.05).There was no statistically significantdifference in IOP and BCVA after surgery between two groups,butpostoperative aqueous flare and Corneal endothelial cell loss weresignificantly lower in the FLACS group(P<0.05). Conclusions:Femtosecond laser-assisted cataract surgery constructed ofsmooth, neat, centrally located anterior capsulotomy,and results insignificantly lower CDE、EPT、balanced salt solution volume.Therefore thefemtosecond laser platform was effective and safe in cataract surgery,as itcould reduce the severity of postoperative inflammation、Corneal endothelialcell loss and postoperative complications.
