PURPOSE: To conduct a material analysis of spontaneously subluxated iris-fixated phakic intraocular lenses (IOLs) using light and scanning electron microscopy. METHODS: Six explanted Artisan/Verisyse and Artiflex/Veriflex IOLs (Ophtec, Groningen, Netherlands/AMO, Santa Ana, CA) were analyzed in a laboratory using light and scanning electron microscopy. Four of the IOLs had been explanted after spontaneous subluxation leading to a decrease in visual acuity, whereas the remaining two IOLs did not demonstrate signs of disenclavation but had been explanted in the course of planned cataract surgery and thus served as the control in this study...

PURPOSE: To compare refractive stability, endothelial cell count (ECC), incidence of complications, and patients' satisfaction between a rigid Verisyse (group I, n = 198) and foldable Veriflex (group II, n = 212) phakic intraocular lenses (pIOL) over 36 months postop. MATERIALS AND METHODS: This was a retrospective study. Patients' satisfaction and incidence of photic phenomena were evaluated at one month and one year postop. Data were analyzed to determine difference between groups for astigmatism, mean spherical equivalent (MRSE), uncorrected (UDVA) and corrected (CDVA) monocular distance visual acuity, complication rate (acute and chronic), and ECC...

AIM: To evaluate efficacy and safety of iris-supported phakic lenses (Verisyse) for treating moderately high myopia. METHODS: This prospective clinical study included 40 eyes from 29 patients, who underwent implantation of Verisyse for correction of myopia from -6.00 to -14.50 diopters (D) in the Eye Clinic ''Svjetlost'', Sarajevo, from January 2011 to January 2014. Uncorrected distance visual acuity (UDVA), manifest residual spherical equivalent(MRSE), postoperative astigmatism, intraocular pressure(IOP), endothelial cell (EC) density were evaluated at one, three, six and twelve months...

BACKGROUND: Evaluation of refractive predictability with retroiridal implantation of a Verisyse(TM) iris-claw lens (AMO) and optimization of the IOL-constants recommended by the manufacturer. PATIENTS AND METHODS: A retrospective study after retroiridal iris-claw lens implantation in the years 2007-2012 including 52 eyes of 50 patients with a lack of capsular support was carried out. Follow-up data was recorded on average 5 weeks after surgery. Demographic data, indications, accompanying diseases, biometrical data and refractive outcome were analysed and an individualization of the intraocular lens constants for the SRK/T-, Holladay-1, Hoffer-Q and Haigis-formula was carried out...

BACKGROUND: Phakic anterior chamber iris-fixated IOL (PIOL) are established for the correction of high myopia. These patients require attention to macular pathologies. This study was to evaluate the quality of imaging through the PIOLs. METHODS: 54 eyes of 31 myopic and hyperopic patients with Verisyse, Verisyse toric, and Veriflex phakic iris-fixated IOL were included. Mean preoperative refraction was -11.0 D and +5.7 D, respectively; mean follow-up time was 7...

PURPOSE: To evaluate the incidence rate and indications for explantation of Verisyse phakic intraocular lenses (pIOLs) over a 13.6 year period. SUBJECTS AND METHODS: Case series describing six cases of explantation of Verisyse pIOLs, out of 213 eyes with Verisyse pIOLs, implanted over a 13.6 year period by one surgeon at one institution, with mean follow-up of 5.6 years per eye. RESULTS: Four pIOLs were removed to facilitate extraction of a visually significant cataract, one was removed due to both cataract formation and development of corneal decompensation, and another was removed due to development of localized peripheral corneal decompensation...

The intraocular correction of aphakia in the anterior chamber currently consists of two options: an angle supported intraocular lens (IOL, Kelman Multiflex) and an iris fixated IOL (Artisan/Verisyse). The angle supported IOL is fixated with four haptic points in the anterior chamber and the iris fixated IOL is enclavated to the anterior iris surface. Acceptable results of both IOLs are reported in the literature; however both IOLs show some long-term complications in some eyes. Alternatives to these anterior chamber IOLs to correct aphakia are the retropupillary fixated Artisan and sclera fixated IOLs...

BACKGROUND: Overview of the retropupillary implantation of iris claw intraocular lenses (Artisan®,Ophtec, Groningen, Niederlande and Verisyse(TM),AMO, Santa Ana CA). MATERIAL AND METHODS: A literature search and review of implantation techniques, patient selection, potential complications and management strategies. RESULTS: This approach has the advantage of a simple implantation technique, an anatomically correct implantation site (as compared to endocapsular implantation) and a relatively low complication rate...

Both choroidal neovascularization during pregnancy, and choroidal neovascularization following implantation of phakic intraocular lenses have been reported in the literature. To our knowledge, this is the first case reported of a gravid woman developing choroidal neovascularization in an eye with a phakic intraocular lens. A 31-year-old woman became aware of her pregnancy three weeks after placement of the Verisyse™ iris-supported phakic intraocular lens. She was at 15 weeks gestation when she developed a Fuch's spot consistent with choroidal neovascularization...

PURPOSE: After implantation of retropupillary fixated iris-claw lenses, changes of the objective refraction can occur depending on the patients' position. The purpose of this study was to evaluate and quantify these changes as well as the influencing factors. METHODS: Within a retrospective study, postoperative refraction visual, acuity and anterior chamber depth after implantation of a retropupillary fixated iris-claw lens (Artisan® / Verisyse®) were measured in 51 eyes (49 patients) depending on their head position...

PURPOSE: Retropupillary fixation of an iris-claw intraocular lens (IOL) (Verisyse, Abbott Medical Optics) was performed for aphakic eyes without sufficient capsular support, and safety and recovery of the procedure were compared with transscleral suturing fixation. METHODS: This interventional case series comprised 11 eyes of 10 aphakic patients without capsular support undergoing retropupillary fixation of the Verisyse, and 21 eyes of 20 patients undergoing transscleral suturing fixation of foldable acrylic IOLs (15 eyes of 14 patients, SuperFlex620H [Rayner Intraocular Lenses Ltd]) and polymethylmethacrylate IOLs (6 eyes of 6 patients, CP60NS [CORNEAL Laboratoire])...

The loss of the corneal endothelial cells, especially in a first postoperative year, has been observed in patients who underwent penetrating keratoplasty (PK). The implantation of new generation of "iris claw" phakic IOL (Verisyse) in refractive cases has been shown to cause clinicaly insignificant endothelial cell loss. In our prospective case series we investigated the endothelial cell loss and clinical outcome in patients that either underwent PK and implantation of PCIOL or PK and implantation of Verisyse IOL...
