Position of angle-supported, iris-fixated, and ciliary sulcus–implanted myopic phakic intraocular lenses evaluated by Scheimpflug photography

Three-year follow-up of subjective vault following myopic implantable collamer lens implantation

“…), and taken under cycloplegic effect in order to avoid potential influence of accommodation-induced changes in the position of the anterior surface of the crystalline lens or the ICL itself on the estimation of the vault value, and above all to make the examinations more repeatable between visits. Statistical analysis was performed using the SPSS statistical package v. 16.0 (SPSS Inc., Chicago, IL, USA). In order to evaluate the changes in vault during the followup period, the sample was stratified in five groups according to the value measured at the first visit 1 week after surgery (baseline): vault 0, vault 1, vault 2, vault 3 and vault 4.…”

“…The most common concerns regarding post-operative ICL complications related to vault value include anterior subcapsular cataract (ASC) [8][9][10][11] and increased intraocular pressure (IOP) [12][13][14], presumably as a result of mechanical contact of ICL with the anterior lens capsule or angle closure, respectively. Furthermore, it has been reported that vault has a tendency to decrease over time [9,10,15,16], leading to an increased risk of cataract formation [10,17,18]. These facts, along with physiologic increase of lens thickness with age [19] and anterior displacement of the lens during accommodation [20], make clinical assessment of vault and follow-up of these patients over time an important part in the evaluation of long-term safety of ICL.…”

Evaluation of pupil diameter after posterior chamber phakic intraocular lens implantation

“…We consider that uncomplicated ICL implantation, taken together with an appropriate ICL size selection, does not induce a significant change in pupil diameter. Recently, the rotating Scheimpflug imaging system (Pentacam Oculus), 16,22 and anterior-segment optical coherence tomograph (Visante OCT Carl Zeiss Meditec, Dublin, CA, USA) 23,24 provided highly accurate and reproducible measurements of anterior-segment biometry and thus become more helpful in evaluating the relationship of the ICL with the pupil metrics. A further study is necessary to confirm the authenticity of the results.…”

Biometrie des vorderen Augensegmentes zur Implantation phaker Vorderkammerlinsen

“…B. Endothelzellverlust, Dezentrierung, Rotation und Kataraktentwicklung induzieren [1,2,6,8,14]. Eine zuverlässige und gleichzeitig praktikable Vermessung des vorderen Augenabschnitts muss daher durchgeführt werden, um die sichere Implantation phaker Intraokularlinsen zu gewähr-leisten.…”
