Corneal cell response after flap creation using a mechanical microkeratome or a 200 kHz femtosecond laser.

Purpose: To compare the inflammatory cell response within the corneal flap interface created by a mechanical microkeratome and a femtosecond laser.

Setting: Department of Ophthalmology, Ludwig-Maximilians-University, Munich, Germany.

Design: Experimental in vitro study.

Evaluation of interface quality in organ-cultured lamellar corneal transplants.

Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical processing. The aim of this study was to investigate the influence of different deswelling times on the cutting plane quality after microkeratome-assisted lamellar dissection.

Two-step LASIK after penetrating keratoplasty.

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, and three months later were evaluated. Keratotomies were performed with the Moria((R)) LSK one and the Amadeus((R)) 2 microkeratome, laser ablation was performed with the Schwind((R)) Keratome I and the Wavelight((R)) Allegretto WaveEyeQ.

Cytoprotective effects of a blue light-filtering intraocular lens on human retinal pigment epithelium by reducing phototoxic effects on vascular endothelial growth factor-alpha, Bax, and Bcl-2 expression.

Purpose: To compare the possible protective effects of the ultraviolet (UV)-filtering and blue light-filtering SN60AT intraocular lens (IOL) and the untinted UV-filtering SA60AT IOL with regard to light-induced stress on human retinal pigment epithelium (RPE).

Setting: Department of Ophthalmology, Ludwig-Maximilians-University, Munich, Germany.

Methods: Primary human RPE cells were exposed to white light, and a tinted or untinted IOL was placed in the light beam.

Performance of the Acri. Smart 46S intraocular lens in pediatric microincision cataract surgery.

Purpose: To evaluate the performance of the microincision Acri. Smart 46S intraocular lens (IOL) (Acri.Tec) in pediatric cataract surgery.
