Abstract Details


The aim of this study is to evaluate the role of the posterior capsule in patients that had been implanted with an accommodative intraocular lens (IOL) that developed a posterior capsule opacification and required a laser YAG capsulotomy.


Vissum, Alicante Spain, Universidad Miguel Hernández.


Ten eyes of patients that underwent micro incisional cataract surgery (MICS) with the implantation of the Lumina accommodative IOL and required a laser YAG capsulotomy due to posterior capsule opacification were included in this study. The uncorrected and corrected distance and near visual acuity (UDVA, CDVA, UNVA, CNVA) were assessed and the defocus curve before and after the capsulotomy.


The mean visual acuities before the capsulotomy were: UDVA 0.74, CDVA 0.92, UNVA 0.67, CNVA 0.64. The mean visual acuities after the capsulotomy were: UDVA 0.71, CDVA 1.0, UNVA 0.74, CNVA 0.73. The defocus curve showed an improvement specially in the near distances (-3.00 diopter to -4.00 diopters)


After capsulotomy there was an improvement in near visual acuity which was reflected in the defocus curve; so, we can conclude that the posterior capsule plays no role in the accommodative process in eyes implanted with an accommodative IOL. To our knowledge this is the first time that the role of the posterior capsule is described, this could be showed due to the fact that the Lumina IOL is implanted at the ciliary sulcus because it has been proven that when presbyopia develops, the ciliary muscle still has its contractive action.
