PURPOSE The point of interest of this retrospective case review is to study refractive changes caused by the hinged lamellar keratotomy and the refractive outcome after laser ablation in a second step within the scope of laser in situ keratomileusis (LASIK) in patients with penetrating keratoplasty. METHODS Data from eight patients obtained before lamellar keratotomy, before laser ablation, a...

Background: The aim of this study was to highlight the structural changes in patients with cataract following surgery and repercussions on anterior pole. Methods: A total 83 diagnosed who underwent uneventful phacoemulsification included. Every patient examined one week prior two weeks after surgery. Pre- postoperative assessment included examination posterior segment, keratometry, optical biom...

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 ...
