Rhegmatogenous retinal detachment associated with choroidal detachment (RRDCD) is a special type of complex retinal detachment, and usually has a poor prognosis. This study aimed to assess the anatomical outcomes of 23-gauge pars plana vitrectomy (23G PPV) combined with phacoemulsification (phaco) and capsulotomy without intraocular lens (IOL) implantation in patients with RRDCD.Seventy-six con...
PURPOSE To evaluate the indications, postoperative visual efficacy, and complication rate after intraocular implantation of an iris-claw aphakic intraocular lens (IOL). SETTING Oxford Eye Hospital, Oxford, United Kingdom. DESIGN Case series. METHODS This chart review comprised eyes with no capsule support that had anterior iris-fixation IOL implantation for aphakia between 2001 and 2009. ...
Pitx3 is a bicoid like homeobox transcription factor of which deficiency in mice is linked with the aphakia phenotype. Mutation in human PITX3 gene is associated with autosomal dominant cataract with variable anterior segment mesenchymal dysgenesis. However, the molecular events causing the morphological changes in aphakia remains unknown. In this study we investigated the behaviour of GFP tagg...
PURPOSE To compare the long-term efficacy of a secondarily implanted flexible angle supported anterior chamber (AC) intraocular lens (IOL) with sclerally fixated IOL as a secondary procedure in patients with aphakia. METHODS Sixty patients with aphakia were recruited for this study. The patients were randomly divided into two groups: Group I patients underwent secondary implantation with AC I...
PURPOSE To compare rates and severity of complications between infants undergoing cataract surgery with and without intraocular lens (IOL) implantation. DESIGN Prospective randomized clinical trial. METHODS A total of 114 infants were enrolled in the Infant Aphakia Treatment Study, a randomized, multi-center (12) clinical trial comparing the treatment of unilateral aphakia in patients under...
Background. To analyze the effects of factors other than the ocular trauma score parameters on visual outcomes in open globe injuries. Methods. Open globe injuries primarily repaired in our hospital were reviewed. The number of surgeries, performance of pars plana vitrectomy (PPV), lens status, affected tissues (corneal, scleral, or corneoscleral), intravitreal hemorrhage, intraocular foreign b...
If contact lens or spectacle correction is not viable, little debate exists that the secondary placement of an intra-ocular lens (IOL) is the method of choice in the absence of capsular support. The choice of IOL mainly depends on the preoperative status of the eye (eg, aphakia in children) and the selected location for the implant. Theoretically, there are several IOL implantation approaches i...
PURPOSE To describe the epidemiology of children submitted to contact lens fit. METHODS Retrospective study of 73 children that had been submitted to contact lens fit at the "Universidade Federal de São Paulo". This study analyzed sex distribution, age, diagnosis, indications and contact lens fitted at first examination. RESULTS 34 children (46.6%) were male and 39 (53.4%) female, aged betw...
PURPOSE To evaluate the technique, efficacy, and safety of posterior iris fixation of iris-claw intraocular lens (IOLs) implantation through a scleral tunnel incision for aphakia correction. DESIGN Noncomparative, interventional case series. METHODS A secondary posterior iris fixation of the Artisan iris-claw IOL (Ophthec BV, Groningen, The Netherlands) was implanted for aphakia correction ...
AIM To explore the application of intraoperative wavefront aberrometry (IWA) for aphakia-based biometry using three existing formulae derived from autorefractive retinoscopy and introducing new improved formulae. METHODS In 74 patients undergoing cataract surgery, three repeated measurements of aphakic spherical equivalent (SE) were taken. All measurements were objectively graded for their qu...
