Possibilities And Problems Of My Lasik Surgery

Lasik is the procedure I finally decided to have done. Its short for Laser Assisted In-situ keratomaleusis. What they do is they cut open the cornea by either using a laser, or using a micro-blade to do it, and then have a laser ablate the eye, shaping ever so subtlety for better vision. I course I was wearing glasses for years, but more and more of my friends had either given up glasses entirely, or seem to only use them for close work.

They first have to give you a thorough examination to see if you qualify to have custom lasik done. The main requirement is that you have a thick enough cornea for them to open it up and shave it a bit. I seem to have fit the bill. Several days before the operation, I went into the doctors office, had my eyes dilated, and then they made a wave map of my entire eye. After doing that, the doctor knew all the mountains and valleys in my eye, back and forth.

If for some odd reason your cornea is too thin and you cannot have lasik done, the new alternative procedure is to have a permanent lens implanted under your iris and over your cornea. Its sort of a permanent contact lens. My surgery went well, but other times there are problems. Lasik surgery can provide very quick improvement of your vision, but in some case the post-operative improvement takes place over time. In the beginning you usually have better vision but often you have some blurry vision and problems with night vision. These effects improve over time. The more experience your doctor has, the less likely, generally speaking, that he will overcorrect your problem. That is if you are very nearsighted , after the procedure you will become slightly farsighted. It is a complication that does and can happen. If necessary you can undergo another lasik procedure to reduce farsightedness. Even with all the computer technology and wave mapping technology, there is still a human element here. If a doctor is correcting nearsightedness he will usually leave you slightly nearsighted, in order to stay on the safe side. As the doctor becomes more experienced, he can go closer to the exact 20/20 vision point. The other problems that ophthalmologists have to watch out are glares and halos. The doctor has to make sure that under low light conditions, pupil fully dilated, your larger dilated pupil can get a big enough corrected light zone.
