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...

Corneal transplantation, as full-thickness transplantation, is an old surgical procedure which has been successfully performed for more than 100 years. However, in a last decade significant changes in surgical technique(s) have been implemented. The reason for such changes is the current trend to replace only the diseased part of the recipient cornea, not the whole cornea. Therefore, if the ant...

Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick anterior lamellae (diameter, 10mm; thickness, 500μm). The laser cuts were made using an LDV ...

PURPOSE The point of interest of this retrospective case review is to study refractive changes caused by the hinged lamellar keratotomy and the refractive outcome after laser ablation in a second step within the scope of laser in situ keratomileusis (LASIK) in patients with penetrating keratoplasty. METHODS Data from eight patients obtained before lamellar keratotomy, before laser ablation, a...

become their better seeing eye. The growing literature on the management of HIV related retinal detachment provides other useful insights into the disease process and also the surgical use of silicone oil. Published series have varied in their reported incidence of proliferative vitreoretinopathy. 5 6 8–11 There is, however, a consensus that epiretinal membrane formation does occur in these cas...

The two main issues that concern glaucoma patients before and after penetrating keratoplasty and posterior lamellar procedures and patients that develop glaucoma after surgery are the risks of graft failure and the aggravation of the glaucoma. Failure of the corneal graft may require regrafting, which increases the risk of developing or aggravating glaucoma, while uncontrolled glaucoma may resu...

Aim: To determine the changes in postkeratoplasty astigmatism induced by lamellar keratotomy. Methods: A prospective, non-randomised comparative trial of patients undergoing a hinged lamellar corneal flap for treatment of significant astigmatism after penetrating keratoplasty. Uncorrected visual acuity, best corrected visual acuity, refraction, and corneal topography were assessed at 1 and 3 mo...
