IMPORTANCE Pediatric primary posterior intraocular lens (IOL) implantation in children older than 24 months has become the standard of care. Results of the Infantile Aphakia Treatment Study have concluded that primary IOL implantation before age 7 months has no advantages over aphakia. The current evidence does not address our understanding of the risks and benefits of primary IOL implantation ...

PURPOSE To evaluate the efficacy, predictability, stability, safety, and complications of secondary anterior iris fixation of the Artisan iris-fixated intraocular lens (IOL) to correct aphakia in eyes without sufficient capsule support. SETTING Department of Ophthalmology, Jinling Hospital, School of Medicine, Nanjing University, Nanjing, China. DESIGN Cohort study. METHODS Eyes having im...

Patients have been very satisfied with these lenses (78% wearing at the end of six months), not the least those with reduced function of the macula. The problems of infection have been discussed, and apart from improvement in lens materials patient selection is of paramount importance. The problem of deposits is presented, but theri elimination will depend on more research into their nature and...

A genetic approach has been established that combines the advantages of blastocyst complementation with the experimental attributes of the developing lens for the functional analysis of genes governing cellular proliferation, terminal differentiation, and apoptosis. This lens complementation system (LCS) makes use of a mutant mouse strain, aphakia (ak), homozygotes of which fail to develop an o...

This Interventional case reports a challenging case of descemet's stripping-automated endothelial keratoplasty (DSAEK) in a young male patient with traumatic aniridia, aphakia, and corneal edema. Surgery was planned in two stages; first was implantation of aniridia intraocular lens (AIOL), few months later, DSAEK procedure was performed. Successful outcome of both procedures was achieved as mea...

We report on 2 infants, one with a bilateral and the other with a unilateral corneal metaplasia. The first case with bilateral corneal metaplasia showed shortening of both upper and lower lids with formation of symblephara. By ultrasonography the right eye presented with microphthalmos, aphakia, and persistent hyaloid, whereas the inner parts of the left eye appeared to be normal. The question ...

INTRODUCTION Implantation of scleral fixation intraocular lens for the surgical management of aphakia cases without capsular support is a safe procedure. METHODS Prospective study was carried out at Lumbini Eye Institute, Bhairahawa. A total of 32 patients underwent scleral fixation intraocular lens implantation within a period of two years from February 2014 to February 2016. RESULTS The a...

A Holstein calf was born with a large protruding right eye and a central corneal opacity. Enucleation was the first choice of treatment. The calf had a good prognosis and was raised for milking purposes. Macroscopically, the enucleated eye was characterized by the protruded cornea, adherence of the iris to the central posterior cornea and aphakia. Microscopically, central corneal thickening and...
