... Abstract Multifocal intraocular lenses (IOLs) have at least two dioptric powers, providing at least two different foci on the same axis. They generate at least two superimposed images of each observed object. Image confusion is reduced by distant power asphericity, near power apodization...

... Abstract Several intraocular lens (IOL) materials and types are currently available. Polymethyl methacrylate IOLs used to be the gold standard, but the inability of folding limits their use to selected countries and patients. Silicone IOLs were used more in the past because they are less...

... with laser in situ keratomileusis seem similar to those with surface ablation, but flap complications can occur. While implantation of either phakic or pseudophakic toric intraocular lenses (IOLs) can generate excellent refractive results, some preoperative thought is required. Phakic toric IOLs cause more...

.... Considerations of Intraocular Lens Placement at Primary Surgery and Timing of Vitreoretinal Intervention The question of whether to implant an IOL at the time of nucleus drop if no PPV is undertaken is contentious. Most vitreoretinal surgeons currently agree that placement of a secure IOL at the time...

... in axial elongation after cataract extraction, the magnitude of this effect is much less than what has been reported in animal models. Choosing an intraocular lens (IOL) power for implantation into a child's eye is complicated by continued ocular growth, the inaccuracy of IOL power calculation formulas...

... Abstract Phakic intraocular lenses (pIOLs) implantation concerns high ametropia. Initially developed for high myopia correction, the treatment fields were expanded to astigmatism and hyperopia corrections. Three basic types of pIOLs allow these corrections: anterior chamber IOLs, iris-fixated...

... children with bilateral cataracts. Visual rehabilitation of children with unilateral cataract requires use of a contact lens or an intraocular lens (IOL) for the best result with a chance for binocularity. Only about 50% of eyes with unilateral infantile cataract will develop vision of better than 20/200...

... lens (IOL) implantation being the standard procedure, the options of procedures for children include: • Lensectomy • Lens aspiration with IOL implantation • Lens aspiration with primary posterior capsulotomy (PPC) and IOL implantation • Lens aspiration with PPC, anterior vitrectomy (AV...

.... If fundus examination is not possible due to lenticular opacity, an ultrasound B-scan is essential prior to planning surgery. A team approach is desirable, and it is best for the surgeon to discuss the need to perform a primary posterior capsulotomy (PPC), anterior vitrectomy (AV) and intraocular lens (IOL...

... uveal reactivity in younger children, leading to increased formation of inflammatory membranes [ 7 ]. A recent study of primary intraocular lens (IOL) implantation in children less than 4 years old with microphthalmia found that 15% of the patients developed VAO [ 8 ]. In fact, in children less than 4...

... manipulations in the anterior chamber (usually due to pseudophakic intraocular lens (IOL) implantation, but it may be related to any other intraocular surgical procedure, obviously including phakic IOL implantation). If the corneal endothelium is damaged during surgery (as often occurs during cataract...

... research questions. In particular, we identified the top 5 questions in the nonconsensus areas that need further research: the suggested minimum age for bilateral primary intraocular lens (IOL) implantation, the IOL power calculation formula, the IOL type for in-the-bag IOL implantation, medications...

...) for the treatment of mild GDM demonstrated that the treatment of mild GDM is associated with a lower rate of induction of labor (IOL; 26.9 vs. 33.8%; p = 0.02). This reduced risk was also confirmed even after excluding cesarean delivery (CD) indications such as malpresentation, placenta previa, oligohydramnios...

... to clear the visual axis and left the lens itself pitted [ 2 ]. Using integrated intraoperative optical coherence tomography (i 2 OCT), we were able to identify that the posterior capsule was sitting further away from the posterior surface of the intraocular lens (IOL) than would have been expected...

... Abstract There are several circumstances where phakic intraocular lenses (IOLs) might be considered in the management of the keratoconic patient, obviously only in the case of a stable refractive situation, sometimes difficult to be defined in this setting. Taking into account that the IOLs...
