New instrument for revision lamellar refractive surgery.

Comparison of two microkeratome systems.

BACKGROUND Microkeratomes are currently used for keratomiluesis in situ (automated lamellar keratoplasty) for myopia and hyperopia and for laser in situ keratomileusis (LASIK). Visual and refractive complications have been reported with these refractive surgical procedures. We compared two microkeratomes in their ability to resect corneal lamellae to gain insight into possible mechanism(s) of r...

Late onset diffuse lamellar keratitis associated with an epithelial defect in six eyes.

PURPOSE To report six cases of late onset diffuse lamellar keratitis associated with epithelial defects 2 to 12 months following uncomplicated laser in situ keratomileusis (LASIK). METHODS Retrospective case series. RESULTS The interface inflammation and epithelial defects were treated aggressively with topical corticosteroids and topical antibiotics with complete resolution over 1 to 2 wee...

The evolution of corneal and refractive surgery with the femtosecond laser

The use of femtosecond lasers has created an evolution in modern corneal and refractive surgery. With accuracy, safety, and repeatability, eye surgeons can utilize the femtosecond laser in almost all anterior refractive procedures; laser in situ keratomileusis (LASIK), small incision lenticule extraction (SMILE), penetrating keratoplasty (PKP), insertion of intracorneal ring segments, anterior ...

A mysterious tale: the search for the cause of 100+ cases of diffuse lamellar keratitis.

Anterior Lamellar Keratoplasty

lar keratoplasty is not new. Mühlbauer was the first to describe a technique for anterior lamellar keratoplasty (ALK) in 1840.1 Penetrating keratoplasty (PKP) has long been the standard treatment for severe corneal pathology. Lamellar surgery has endured significant technical challenges since its inception. The posterior corneal surface is invisible through an operating microscope, due to the s...
