To evaluate the functional results after bilateral implantation of multifocal IOL with different power (SV25T0 add+2.5 D, SN6AD1 add +3.0 D) in both eyes.
Ophthalmology unit, department of Neurosciences, University of Verona, Verona Italy
45 patients were enrolled, all affected by bilateral cataract and without other eye diseases. They were divided in three groups, each composed of 15 people. All patients underwent phacoemulsification and multifocal intraocular lens implantation in both eyes. Group 1 received a +3,00 IOL , Group 2 received the same lens, but with a +2,50 D addiction, whereas Group 3 received a combination of +3,0 D and +2,5 D in both eyes. 6 months postoperatively different parameter were evaluated: Visual acuity (UCVA), best corrected visual acuity (BCVA), uncorrected intermediate (UIVA), uncorrected near (UNVA), and best distance corrected near visual acuity (BDCNVA). Contrast sensitivity, reading speed, defocus curve, patient satisfaction and spectacle independence were also evaluated.
None differences were found in UCVA, BCVA among the three groups. Group 2 had the best UIVA. Contrast sensitivity was found to be better in groups 2 and 3, reading speed was found to be better in groups 1 and 3. Defocus curve with binocular vision showed that group 3 had a bigger visual range from all distances.
Combining these type of IOL seems to provide a bigger visual range from all distances, assuring a good visual quality and spectacle independence.
