The following preoperative data collected: age, gender, type care funding source, surgical technique, best-corrected acuity, manifest sphere cylinder refractive...
Donated corneas are classified as tectonic if there defects within any layers of the cornea which would prevent a satisfactory visual outcome after transplantation. This study aimed to evaluate whether some have sufficient endothelial characteristics allow their use in posterior lamellar keratoplasty, and explored reclassification for this sight-improving procedure.A retrospective review all corneal tissues preserved by Sorocaba Eye Bank from January April 2014 was performed. All donated...

The phakic intraocular lenses (pIOLs) are a good option for the correction of high refractive errors. According to their anatomical position there two types pIOLs: anterior or posterior chamber. chamber pIOL may be iris-fixated angle-supported. pIOLs available not only myopia correction, but also hyperopia and astigmatism. During last decades many modifications on designs were proposed in order reduce late complications, such as progressive endothelial cell loss. [...]
