Cataract Extraction and Toric Intraocular Lens Implantation for the Management of Pellucid Marginal Degeneration and Cataract

We report cataract surgery with toric intraocular lens implantation for the management of senile cataract combined with pellucid marginal degeneration. A 72-year-old man with bilateral senile cataract and significant against-the-rule astigmatism sought counseling for blurry vision and glare, mostly in the right eye. Based on ophthalmic examination and corneal topography, a diagnosis of pellucid...

Progression of pellucid marginal degeneration and higher-order wavefront aberration of the cornea.

PURPOSE To report the time course of changes in corneal wavefront aberrations in a patient with pellucid marginal degeneration. CASE A 59-year-old man with pellucid marginal degeneration was followed-up annually with slit-lamp microscopy and videokeratography for 11 years. The anterior corneal height data of the videokeratography were expanded into the set of orthogonal Zernike polynomials to...

Actual Indications for Intracorneal Ring Segment Implantation in Keratoconus

Intracorneal ring segments (ICRS) are small synthetic implements designed to achieve refractive adjustment by flattening the cornea. Three common types of commercially available ICRS are Intacs, Keraring and Ferrara rings. Low myopia was the initial indication for implantation of ICRS, and indications later included ectatic corneal diseases (such as keratoconus and pellucid marginal degeneratio...

Repair of Spontaneous Corneal Perforation in Pellucid Marginal Degeneration Using Amniotic Membrane

A 47-year-old woman with a history of pellucid marginal degeneration was referred for management of hydrops and peripheral perforation of the right cornea. The initial management with cyanoacrylate tissue adhesive and bandage contact lens did not preclude aqueous leakage the next day. Amniotic membrane grafting using both a surgical graft and a bandage patch was thus performed in the operating ...
