Since LASIK is a high tech sort of medical procedure, then why not wait awhile for it to get even better and less expensive? That is a reasonable question, and one that many people ask themselves and sometimes even ask us during their consultation. If there has never been a better time to have LASIK than today, then why not wait until tomorrow and see if it gets even better? While this many times makes sense when considering other high tech purchases like computers or TV's it is not really necessary in regards to LASIK. Even in computers, one has to balance the wait with what they will be missing during that time. In the case of LASIK we are in a technology that has reached maturity, where the incremental changes are very small compared to the benefits derived. Even more importantly, we have the experience to know how well what we currently using works for a large variety of patients.

Recently I have been investigating cameras from Nikon and when you look at what makes the difference between a $200 Coolpix and a $5200 D3S model, you can learn something important about LASIK. In bright light under ideal circumstances they both take great pictures. Why are these two camera that are 25 times difference in price (and the Coolpix is much easier to carry around) is the reason that professional photographers choose the D3S? It must be more than to look cool carrying around a big impressive looking camera. The answer is that It takes a lot more money and a much bulkier camera to do what the D3 can do as compared to the Coolpix. In a phrase the difference is low light capability. The D3 can take pictures that still look good in very dim light whereas the Coolpix (without a flash) cannot. In bright light with high contrast targets, both cameras can easily give 20/20 type sharpness but obviously this is not the whole story or NASA would not have decided to lug some D3S cameras into outer space if a smaller camera would work just as well.
