Up To 4 Years Visual Outcomes And Posterior Capsule Opacification Rate In Three Types Of Hydrophilic Different Optic Design Intraocular Lens With 360 Eyes On File

Eye Centre Prague, Prague, Czech republic

Patients who underwent bilateral cataract surgery with implantation of one of the 3 type intraocular lens: monofocal (Softec HD), asymmetric refractive (SBL-3) or trifocal diffractive (AT LISA TRI) in both eyes were included. All surgeries were performed by two experience surgeons with polishing of posterior capsule. Patients were evaluated at follow-up visit in period 18 to 48 months after the surgery. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA), were compared between groups postoperatively. Incidence of required Nd:YAG capsulotomies was recorded and compared between groups. 

There were 120 eyes of 60 patients in each group included. Follow-up period was 37 months in monofocal group, 38 months in asymmetric refractive group and 38 months in diffractive trifocal group. The rate of Nd:YAG capsulotomy treatment was 59% in monofocal group, 60% in refractive IOL group and 53% in trifocal group. Time period of significant PCO requiring Nd:YAG capsulotomy was 30 months in monofocal group, 28 months in refractive IOL group and 25 months in trifocal group. Number of needed capsulotomies in first 12 months was 3, 10 and 14 in monofocal, refractive and trifocal group respectively with significantly higher rate in refractive and trifocal group than monofocal group (p <  0.05).
