Toric bag-in-the-lens implantation: why and how to implant

Abstract

More complex optics of intraocular lenses (IOLs) are implanted nowadays, with the aim to correct the ocular sphere and cylinder simultaneously. Alignment of the IOL is a new area of interest for the ophthalmologist. It is well-known that optimal lens alignment will result in optimal quality of the image as perceived by the patient. The bag-in-the-lens implantation is the first IOL that allows surgeon-controlled alignment. Besides its ability to eradicate posterior capsule opacification, its rotation stability was found to be extremely reliable. This new IOL concept was thus considered suitable for going toric. Patients with a cylinder correction, at the lenticular plane, ranging from 2.5 to 6.5 D (mean: 4 D), were selected. The results are very positive, and thus it can be concluded that this new concept of intraocular lens implantation shows a second major advantage, which is the correction of corneal astigmatism at the lenticular plane of medium high to very high dioptrical cylinder powers.
