LASIK

LASIK (Laser-Assisted in Situ Keratomileusis) is performed for correcting refractive errors of the eye like myopia, hypermetropia and astigmatism. It involves creating a flap of cornea with an instrument called microkeratome, reflecting it back, and zapping the cornea with an Excimer laser. The laser, basically 'sculpts' the cornea to a predetermined level so as to ensure optimum vision. The flap of cornea is then placed back to the original position. The procedure is done under topical anesthesia and the patient can return back home shortly after the procedure.


Complications after LASIK are also not uncommon. In some cases, there might be a residual refractive error, and the patient might have to continue with the glasses. In some cases, there may be complications related to the flap. Also, structurally, the cornea is weakened slightly than it was before.

Nevertheless, in carefully selected cases, Lasik is an effective and safe procedure. LASIK is not indicated for very high refractive errors or in eyes with preexisting disease like dry eyes etc. Your eye doctor, after a thorough assessment, would be able to say if you are the right candidate. Make sure you know about all the complications and the level of vision you are likely to get, before proceeding.

Amazing Derren Brown

I am a big fan of Derren Brown, the famous English mentalist. He harnesses the mysterious and powerful effects of the brain by suggestion, tricks of the mind, NLP, hypnosis etc. There is no magic involved, just a perfect understanding of how the mind works and using it to bamboozle people.

When a series of commands is issued rapidly and sometimes confusingly, many at the other end up doing what they are told.

I have many favorites but think this is hilarious. A poor guy ends up giving his wallet, and much more, to Derren. Of course, it may not work on any one but then, Derren has a knack of spotting the most suggestible person!




"Trains of thought" is equally amazing!( instant hypnosis at work!)
