PURPOSE Present an analysis methodology for developing and evaluating accommodating intraocular lenses incorporating a deformable interface. METHODS The next generation design of extruded gel interface intraocular lens is presented. A prototype based upon similar previously in vivo proven design was tested with measurements of actuation force, lens power, interface contour, optical transfer f...

OBJECTIVES To evaluate the movement from their initial set position of subluxated intraocular lenses (IOL) in pig eyes following Nd: YAG laser capsulotomy. METHODS An extracapsular surgical intervention of the transparent crystalline lens was performed on 15 pig eyes. After the introduction of an intraocular lens into the capsular sac, a zonular dialysis was carried out to observe the shift o...

The use of multifocal intraocular lenses (IOLs) is a great advance in the treatment of patients with cataract allowing near and distance uncorrected visual acuity recovery. However patients with some degrees of corneal astigmatism have some limitations. We present 3 cases that were indicated for phacoemulsitfication and multifocal intraocular lens implant (AcrySof Restor, Alcon Labs) after limb...

PURPOSE To investigate the feasibility of estimating effective lens position (ELP) and calculating intraocular lens power using corneal height (CH), as measured using anterior segment optical coherence tomography (AS-OCT), in patients who have undergone corneal refractive surgery. METHODS This study included 23 patients (30 eyes) who have undergone myopic corneal refractive surgery and subseq...

OBJECTIVE To report a rare case of intraocular lens (ACIOL) opacification in the anterior chamber in an adolescent and to discuss the possible mechanism of its occurrence and the ways of its prevention. CASE A 16-year-old male underwent cataract surgery for developmental cataract with placement of a foldable posterior chamber IOL in the anterior chamber. There was subsequent opacification of ...

We propose a complete methodology to develop custom monofocal Intraocular Lens (IOL) designs and evaluate their performance on-axis based on an analytical formulation. The analytical formulation was based on Gaussian and primary aberration theory applied to custom (individual biometric data) and realistic (multilayer cornea and thick IOL) pseudoaphakic eye models. Gradient-based optimization al...

PURPOSE To compare the optical performance of 6 presbyopia-correcting intraocular lenses (IOLs) of different designs (accommodating or multifocal and aspheric or spheric). SETTING Alcon Laboratories, Inc., Fort Worth, Texas, USA. METHODS The optical performance of 6 IOLs were compared using modulation transfer function (MTF) and the United States Air Force 1951 Resolution Target (AFT) testi...
