What is the role of organizational readiness and IT business alignment in the adoption process of an ITsupported interorganizational linkage (IOL)? In this paper, we claim that achieving a proper level of organizational readiness is crucial for the successful adoption of IOL. We thus focus on intraorganizational factors that potentially impact the effectiveness of preparatory activities towards...

Intraocular lens (IOL) power calculations are known to be difficult in eyes that have had corneal refractive surgery and several methods have been proposed to estimate IOL power. Among the methods not requiring preoperative data, the apahakic refraction technique has been successfully used to calculate IOL power in post-refractive cases and other conditions that cause unreliability in standard ...

In an attempt to assess the effect of posterior chamber intraocular lens (IOL) implantation on the outcome of combined extracapsular cataract extraction (ECCE) and trabeculectomy we compared 23 eyes subjected to ECCE and trabeculectomy with 23 eyes subjected to a triple procedure-that is, with the addition of IOL implantation. The results showed that IOL implantation did not have a detrimental ...

We describe a patient with flap decentration after laser in situ keratomileusis (LASIK) and subsequent phakic toric intraocular lens (IOL) implantation. A 19-year-old man with mixed astigmatism had LASIK in the left eye complicated by flap decentration. Laser ablation was abandoned and implantation of a phakic toric IOL was done. Ten months after IOL implantation, the uncorrected visual acuity ...

PURPOSE To investigate in vitro how the posterior convexity of an intraocular lens (IOL) affected the migration of lens epithelial cells (LECs) under its optic. METHODS Porcine LECs were cultured for 9 days with polymethylmethacrylate (PMMA) IOLs in a cell culture chamber insert containing a collagen membrane on which the IOLs were implanted. The central sagittal optic depths of the implanted...

PURPOSE To determine the accuracy of intraocular lens (IOL) power calculations in eyes with high myopia and to suggest adjusted constants for these cases. SETTING Centre for Ophthalmology, Eberhard-Karls-University, Tuebingen, Germany. METHODS Patients with high myopia having phacoemulsification with implantation of an AcrySof MA60MA IOL (power range +5.00 to -5.00 diopters [D]) were evalua...

Purpose To compare the performance of OKULIX ray-tracing software with SRK-T and Hoffer Q formula in intraocular lens (IOL) power calculation in patients presenting with cataract. Methods In this prospective study, 104 eyes of 104 patients with cataract who underwent phacoemulsification and IOL implantation were recruited. Three IOL brands were used and for all eyes, IOL power calculation was...

RATIONALE Although transscleral-fixated intraocular lens (IOL) implantation has been the most frequently chosen treatment for patients with inadequate capsule support, the ghost pupillary capture phenomenon did not cause enough attention. PATIENT CONCERNS We present an unusual case withintermittent pupillary capture of intraocular lens. DIAGNOSIS After 5 minutes staying in the dark environm...

We present the possibility of using a triplet as an intraocular lens (IOL). The matrix method was used to calculate the power of this triplet for high myopia. The thickness of the lens, the distances between the edges of the IOL and the endothelium, the distances between the edges of the IOL and the iris, and the nfluence of axial displacement have been analyzed. We have also compared the size,...

BACKGROUND To determine if a method for irrigation and aspiration (I/A) during cataract surgery provides effective removal of ophthalmic viscoelastic device (OVD). METHODS Japanese porcine eyes were used to evaluate I/A performance with Technique 1 (the I/A tip placed on the center of the anterior surface of the IOL), Technique 2 (the I/A tip alternately pressed near the edge of the IOL optic...
