Dry Eye Afflicts Many Menopausal Women
Women who are in the midst of menopause, who are close to it, or who have just finished it are likely to experience dry eye syndrome, according to recent research.
The condition can be caused by aging, LASIK eye surgery, inflammation and various diseases. "[But] for many women, dry eye is related to the change in hormone levels of menopause," remarked Phyllis E. Greenberger, president and chief executive officer of the Society for Women's Health Research. She said about 3.2 million American women above age 50 are afflicted by chronic dry eye.

Pregnancy and LASIK Don't Mix
When a woman is pregnant or breastfeeding, her hormonal balance shifts dramatically. This causes her body to retain more fluid. And when this happens, her eyes' lenses swell, too, making a correct diagnosis to fix her vision problems with LASIK surgery all but impossible.
When the lens swells, it changes how a woman sees, making her more nearsighted, farsighted or astigmatic. But when her pregnancy is over, and when she stops lactating, her hormones - and her eyes' lenses - return to normal. If a LASIK diagnosis is performed on a woman during the period when her lenses are distorted, the readings will be invalid for her normal bodily state.

Avoiding Lasik Surgery Night-Vision Problems
All too often, problems with a patient's night vision have resulted following laser eye surgery - problems such as night glare, haloes and rings.
But these problems can be minimized, or even eliminated, by proper patient screening, skilled surgical manipulation and the proper, most up-to-date excimer laser technology.

Lasik Innovation Produces Improved Results
In a recent study, a procedure called wavefront-guided Lasik surgery has produced better results in the area of night vision than conventional Lasik surgery.
"Average night-driving performance was reduced after conventional Lasik and improved after wavefront-guided," said Steven C. Schallhorn, at a Berlin meeting of the European Society of Cataract and Refractive Surgeons. "There was a significant loss in a fair number of eyes with conventional and a low percentage with wavefront-guided."

La Fuerza Aérea permite a los pilotos volar con una cirugía Lasik
Por primera vez la fuerza aérea Estadounidense está permitiendo volar a los aspirantes a pilotos y a los miembros de la tripulación aérea, aún si se han sometido a una cirugía ocular Lasik.
Desde el 2001, la fuerza aérea ha permitido a los candidatos a pilotos o miembros de tripulación de que experimenten en determinados sitios, si es que han tenido una cirugía ocular correctiva conocida como PRK (Photo Refractive keratectomy/ Queratotomía fotorefractiva).
La fuerza aérea ha dicho que necesitaba más tiempo para evaluar la cirugía LASIK, que es un procedimiento mucho más nuevo.
Al igual que el PRK, la cirugía LASIK es realizada con un láser para cambiar la forma de la córnea, la cobertura clara del ojo. Sin embargo, en un procedimiento LASIK, los cirujanos utilizan un bisturí para cortar un gajo en la córnea a diferencia del procedimiento PRK.
Los cirujanos de la fuerza aérea estaban preocupados por el hecho de pensar de cómo este colgajo del LASIK se mantendría con los pilotos y miembros de la tripulación volando en ambientes de gran altitud y bajo oxígeno, especialmente en una evacuación de emergencia. Los estudios ahora muestran que existe muy poco o prácticamente ningún efecto cuando los ojos tratados con LASIK pasan a través de una ráfaga de viento después de una expulsión de la aeronave o cuando son expuestos a una gran altitud.
Con la prolongada guerra en Irak y la expansión del servicio militar, la ampliación de los requisitos para el vuelo llega en muy buen momento.

New Lasic
Lasik is a new procedure that borrows technology from laser keratotomy and radial keratotomy to correct near sightedness and astigmatism. To correct near sightedness, doctors try to change the way light is refracted through the eye.
