PURPOSE: Anterior iris-claw phakic intraocular lens (pIOL) implantation is a treatment option for refractive, ametropic patients. However, the postoperative accommodative ability has not been systematically researched. Dynamic stimulation aberrometry allows the objective and dynamical measurement of accommodation by observing ocular aberrations during the accommodation process. We investigated the dynamic accommodative ability after pIOL implantation compared with a healthy age- and gender-matched control group...

Iris-fixated intraocular lens (IOL) is considered a safe and effective option for the correction of aphakia in patients with insufficient capsular support. This systematic review aims to summarize the existing evidence about the Artisan/Verisyse IOLs and to assess the influence of the IOL position on the postoperative outcomes. Three different databases were used for this systematic review and metaanalysis (PubMED, Scopus, and Embase). We searched for case series or clinical trials comparing the prepupillary versus retropupillary Artisan/Verisyse implantation...

Pre- and postoperative fifth-year spheric equivalent (SE) of manifest refraction values, uncorrected and corrected distance visual acuities (UDVA and CDVA, respectively), and endothelial cell density (ECD) values were recorded...

Iris-claw lenses have gained increasing popularity over the last years and are by many surgeons regarded as viable options in eyes with insufficient capsular or zonular support. The iris-claw lens has two haptics with fine fissures for folding (enclavating) the mid-peripheral part of the iris stroma and can either be placed in front of or posterior to the iris. In particular, the retropupillary implantation has been increasingly chosen probably due to having an anatomical position similar to that of the crystalline lens...

PURPOSE: To evaluate the surgical outcomes and feasibility of a novel approach for scleral-fixation using a single-piece acrylic foldable Carlevale lens (Soleko). METHODS: Eighteen eyes of 18 patients with aphakia, dislocated IOL, subluxated lens, anisometropia, perforated trauma, and retinal detachment who underwent IOL implantation with a Carlevale lens were evaluated. All the patients underwent a standard ophthalmologic examination. Anterior segment (AS)-OCT was used postoperatively to check plugs positioning and IOL tilt...

PURPOSE: To evaluate the influence of the type of the keratectasia and preoperative keratometry readings on the efficacy of implantation of iris-fixated phakic anterior chamber intraocular lenses (pIOL) in patients with keratoconus. METHODS: In this retrospective study, iris-fixated pIOLs (Artisan/Artiflex (Ophtec®), Verisyse/Veriflex (AMO®)) were implanted in 38 eyes of 22 patients with stable keratoconus. Thirty-six eyes underwent corneal crosslinking (CXL) prior to the lens implantation...

PURPOSE: To compare the effect of three different phakic intraocular lenses (pIOLs) on the corneal endothelial cell density (ECD).
