Clinical Outcomes of an Asymmetric Model of Intrastromal Corneal Ring Segments for the Correction of Keratoconus.

Purpose: To evaluate the clinical outcomes of a new model of intrastromal corneal ring segments (ICRSs) (Keraring AS) in patients with keratoconus and quantify subsequent changes in refraction and corneal topography.

Methods: This nonrandomized, single-center, retrospective observational study explores the effect of progressive thickness ICRS implantation in patients with keratoconus with a 3-month follow-up. After creating an intrastromal tunnel using a femtosecond laser, 1 or 2 ICRSs of progressive thicknesses (150/250 μm or 200/300 μm) and 160-degree arc length were implanted.

Ocular involvement in epidermolysis bullosa acquisita with long-term follow-up.

Background/aims: To describe the ocular manifestations associated with epidermolysis bullosa acquisita (EBA).

Methods: This retrospective study was conducted at a tertiary bullous disease clinic. Consecutive patients were enrolled with biopsy proven diagnosis of EBA, with ocular involvement and a follow-up of at least 36 months.

Corneal elevation topography: best fit sphere, elevation distance, asphericity, toricity, and clinical implications.

Purpose: To describe the effect of the corneal asphericity and toricity on the map patterns and best fit sphere (BFS) characteristics in elevation topography.

Methods: The corneal surface was modeled as a biconic surface of principal radii and asphericity values of r1 and r2 and Q1 and Q2, respectively. The apex of the biconic surface corresponded to the origin of a polar coordinates system.

[Scleritis: when might a systemic disease be involved?].

Scleritis is typically a severe painful inflammatory disorder of the eye. This process may involve the sclera but also the cornea, adjacent episclera, and underlying uvea and therefore threaten vision. Careful clinical history taking, detailed ocular examination, appropriate investigation for systemic disease, and timely intervention with the use of immunosuppressive drugs when necessary has improved the long-term outcome of patients with scleritis.

Assessment of patient satisfaction with outcomes of and ophthalmic care for cataract surgery.

Purpose: To assess patient satisfaction with cataract surgery care.

Setting: Private and public health ophthalmic centers, France.

Methods: This prospective longitudinal multicenter observational study enrolled patients attending consultation for a preoperative visit from September 2007 to February 2008.
