The Clinical Effect Of Femtosecond Cataract Surgery Combined With Trifocal Intraocular Lens Implantation

Objective:To evaluate the clinical efficacy of femtosecond laser-assisted cataract surgery combined with trifocal intraocular lens(IOL)implantation.Methods:From September 2016 to November 2017,42 cases(including 59 eyes)of cataract patients receiving trifocal IOL implantation in Shanxi Eye Hospital were retrospectively enrolled in this study.Moreover,the visual and refractive outcomes,defocus curve,refractive stability,high order aberrations,patient satisfaction,and spectacle independence were evaluated at 1 week,1 month,3 months and 6 months after surgery,respectively.Results:All patients had attained good visual acuity of > 0.1 logMAR at different distances during the follow-up period;besides,the visual acuity at each distance was remarkably higher compared with that before surgery(P<0.05).The defocus curve had displayed no significant decrease between 0D and-2.5D at 6 months postoperatively,with the visual acuity of > 0.1 logMAR.At 6 months postoperatively,62.7% eyes had a spherical equivalent(SE)of ±0.25 D,and 88% eyes had a SE of ±0.50 D.The incidences of high order aberrations,coma,spherical aberration and trefoil of all eyes were evidently lower than those before surgery,and the difference was statistically significant(P<0.05).Conclusion:Femtosecond laser-assisted cataract surgery combined with trifocal IOL implantation can provide patient with a comfortable and natural full-range vision,which can greatly improve the postoperative satisfaction of patients.
