Collagen-Based Artificial Cornea for Lamellar Keratoplasty: An Early Case Report.

Purpose: The aim of this study was to evaluate Viscoll collagen membrane (VCM) for lamellar keratoplasty.

Methods: A 54-year-old man with grade 4 recurrent pterygium underwent lamellar keratoplasty using VCM as the graft material. Standard keratoplasty postoperative treatments, including topical antibiotic-corticosteroid and artificial tears, were administered.

[Determination of retention during phacoemulsification with AOL in patients with open-angle glaucoma].

Phacoemulsification is the most sparing technique of cataract removal in patients with open-angle glaucoma. The retention of intraocular fluid should be determined to choose a pathogenetically oriented antiglaucoma operation for uncompensated open-angle glaucoma (OAG). The study of the Schlemm's canal retrograde blood filling phenomenon may be a technique of the most informative value.
