[Severe bilateral capsulorhexis contraction after cataract surgery in myotonic dystrophy: a case report].

Introduction: The Authors report the case of a 50-Year-old man with myotonic dystrophy, who developed severe bilateral capsulorhexis contracture after uneventful cataract surgery.

Observation: Phacoemulsification was performed in both eyes with implantation of intraocular lenses. The patient came to complain of decreased vision in both eyes (4/10 Parinaud 4).

[Apoptosis and the ocular surface].

Apoptosis, or programmed cell death, is an active phenomenon that plays a major role in most mechanisms of regulation, differentiation and wound healing. Mostly studied in the retina, apoptosis is also extensively involved in the anterior segment, especially the ocular surface. Apoptosis of keratocytes is a rapid phenomenon following excimer refractive surgery.

Cornea in Marfan disease: Orbscan and in vivo confocal microscopy analysis.

Purpose: To investigate corneal thickness, curvature, and morphology with the Orbscan Topography System I (Bausch & Lomb, Inc., Salt Lake City, UT) in patients with Marfan syndrome (MFS) and to study MFS with in vivo confocal microscopy.

Methods: This prospective, clinical, comparative case series included 60 eyes of 31 patients with MFS and 32 eyes of 17 control subjects.

[Influence of corneal refractive surgery on the lacrymal film].

Functional and clinical signs of ocular surface involvement are observed after corneal refractive surgery (LASIK or PRK) and are evocative of dry eye syndrome. The surgical process induces a total or partial section or abrasion of the corneal-sensitive nerves. This anatomical consequence of surgery is responsible for a lachrymal dysregulation with reduced tear production.

[Corneal stromal changes after LASIK].

Purpose: To assess stromal modifications after laser in situ keratomileusis (LASIK) for myopia using in vivo confocal microscopy.

Methods: Thirteen eyes from 10 patients were examined before surgery and at days 8 and 30 after surgery using an in vivo confocal microscope coupled with a Z-Scan system. Stromal morphological changes, keratocyte density, flap thickness, and subclinical haze were evaluated and compared at different time points.
