BACKGROUND Presbyopic inlays have mostly been implanted under a corneal flap. Implantation in a pocket has advantages including less postoperative dry eye and neurotrophic effect, and better biomechanical corneal stability. This study investigated the effect of different pocket and flocket dimensions on corneal stability and refractive power after Raindrop™ implantation, and the associated woun...
AIM To study the influence of cryoprotectant, cooling rate, and warming rate on recovery and viability of keratocytes from corneas for cryolathing. METHODS Corneas were frozen at -50 degrees C for 2 minutes either after exposure to 10% dimethyl sulphoxide in Eagle's MEM for 15 minutes at room temperature (about 22 degrees C), or without earlier exposure to the cryoprotectant. Corneas were coo...
PURPOSE To present light and electron microscopic as well as immunohistochemical findings after corneal cross-linking (CXL). METHODS Six keratoconus corneas after CXL, 12 keratoconus corneas without CXL, and 7 normal corneas were examined by light microscopy, indirect immunohistochemistry using antibodies against proapoptotic BAX, antiapoptotic survivin, and BCL-2, and anti-smooth muscle acti...
PURPOSE We investigated the morphologic characteristics and proliferation of rabbit corneal stromal cells (CSCs) onto scaffolds under simulated microgravity. METHODS Rabbit CSCs were cultured under simulated microgravity (SMG) and static condition. Complexes of collagen-chitosan-sodium hyaluronate with pores were used as scaffolds. Rotational speed was set at 15, 20, and 30 rpm in the first, ...
Keratocyte density 3 months, 15 months, and 3 years after corneal surface ablation with mitomycin C.
PURPOSE To study the effects of surface ablation with mitomycin C (MMC) on keratocyte population. DESIGN Prospective, nonrandomized, interventional, comparative case series. METHODS Thirty two eyes treated with surface ablation with 0.02% MMC were compared with nontreated eyes at Vissum Santa Hortensia, Madrid, Spain. Keratocyte density was measured with the Heidelberg Retina Tomograph II (...
