To evaluate the late post operative results of the multifocal intraocular lens implantation (IOL) in pediatric cases.
Ege University, Faculty of Medicine, Ophthalmology Department
Eleven eyes of 9 patients aged 5 to 11 years who underwent multifocal IOL implantation were enrolled. Pre and post operative visual acuity with and without distance correction, post operative distance corrected and uncorrected near visual acuity, spectacle usage, binocular function, contrast sensitivity, complications and subjective symptoms such as glare and halos were evaluated.
Standart surgical procedure as lensectomy and diffractive multifocal IOL (Acrysof Restor SN6AD3) implantation was performed to all eyes. The mean age was 7.18ḟ2.08 and the mean follow up period was 43.8ḟ13.2 months. Pre-operative mean best corrected visual acuity was 0.16ḟ0.11. The post-operative mean visual acuity with distance correction was 0.77ḟ0.18 at the last follow-up. Post operative near visual acuity with distance correction was 0.34ḟ0.13 whereas with additional near correction it was 0.52ḟ0.13 in late period. Two patients were using spectacles for distance but none of them have reported any need for an additional plus add for near vision. Contrast sensitivity was effected in 75% of eyes only in higher spatial frequencies and in 12.5% both in lower and higher spatial frequencies. Posterior capsuler opacification developed in all patients at the end of 18 month, in 8 eyes YAG laser capsulotomy solve the problem whereas pars plana capsulotomy was required in 3 eyes.
Implantation of multifocal IOLs seems to be a satisfactory alternative in pediatric population above age 5, with better control of ambliyopia, more patient comfort and less spectacle dependency. Long term studies with big case series are needed to show the safety and efficacy of multifocal IOLs in this age group.
