Malini Veerappan, Garrick Chak, Christine Shieh, Pratap Challa
INTRODUCTION: Maroteaux-Lamy syndrome (MLS) is a rare progressive condition characterized by inflammation and scarring of multiple organs. Ocular complications caused by anterior segment abnormalities commonly cause visual impairment in MLS. Angle-closure glaucoma is one such complication, but there are limited data on presentation, workup, and management of this condition. CASE PRESENTATION: This case report describes an atypical presentation of acute angle-closure glaucoma in a patient with MLS despite a prior prophylactic laser peripheral iridotomy-which would typically prevent an acute angle-closure attack-that was patent and intact at the time of angle closure...

Fritz H Hengerer, Ina Conrad-Hengerer
In refractive surgery the removal of the natural lens followed by implantation of an artificial intraocular lens has been an established method to treat refractive errors. The term "clear lens exchange" separates this approach from cataract surgery, where a cloudy lens has to be removed. With regard to currently available intraocular lens technologies, there is a wide range to correct myopia, hyperopia as well as astigmatism. Trifocal or extended depth-of-focus lenses (EDOF) even with a toric component offer the patients a potential benefit to further address presbyopia, respectively...

Raffaele Nuzzi, Francesca Monteu, Federico Tridico
Radial keratotomy is a refractive surgical technique, widely used in the 80s and early 90s to correct myopia and astigmatism, but now overcome by more recent laser techniques. Important consequences, often in patients with more than 45 years of age, are progressive hyperopic shift and/or an increase in corneal astigmatism, whose main cause seems to be an increase in the curvature radius of the central portion of the cornea. This seems to be due to radial keratotomy incisions - with the consequent need for cross-linking - intraocular pressure, and corneal biomechanical parameters...
