Corneal & refractive surgery.
Excimer lasers and high technology instrumentation have ushered in a new era of vision improvement surgery in Hawaii, replacing the more traditional forms of refractive surgery: cataract surgery, corneal transplant surgery, and radial keratotomy. Corneal surgery has been enhanced by new techniques of microsurgery and a more effective tissue procurement system for donor corneal tissue. Several l...
متن کاملKeratocyte apoptosis after corneal surgery.
PURPOSE Programmed cell death (apoptosis) is the controlled death of cells that occurs with minimal collateral damage to surrounding cells or tissue during development, homeostasis, and wound healing. The authors hypothesize the keratocyte apoptosis is an initiating factor in the wound-healing response after refractive surgical procedures. To evaluate the effects of different corneal manipulati...
متن کاملGlaucoma following Corneal Transplant Surgery
Post-PK glaucoma is an important cause for irreversible visual loss and graft failure after penetrating keratoplasty. The etiology for this disorder is multifactorial and with the use of new diagnostic equipment it is now possible to elucidate the exact pathophysiology of this condition. A clear understanding of the various mechanisms which operate during different time frames following keratop...
متن کاملCorneal or lens refractive surgery?
E xcimer lasers are used today practically all over the world to treat refractive errors. This provides us with a wealth of data and findings that must be analyzed, presented, interpreted, and discussed. One major finding is already certain: the absolute and indisputable necessity of refractive surgery. Even those who are skeptical about refrac-tive surgery must accept this. Patients simply do ...
متن کاملEquation for corneal asphericity after corneal refractive surgery.
PURPOSE To determine the exact theoretical asphericity after refractive surgery when the parabolic approximation of the Munnerlyn formula is utilized. METHOD From a least-square analysis and considering the conicoid model for anterior cornea, we calculated the final asphericity (p'-factor) from the preoperative asphericity and the radii before and after surgery. RESULTS The final p'-factor ...
