Why don’t you see clearly? Why do you need spectacles or contact lenses? First of all, you need to understand something about the eye, so that you can understand better the concept of  refractive errors of the eye, which is the reason you need spectacles and contact lenses.

If you don’t like spectacles or contact lenses, and want a life free from spectacles and contact lenses, you need to consider laser in-situ keratomelieusis, or in short LASIK. You need to know why LASIK allows you to correct refractive errors, and see clearly without spectacles and contact lenses.

If you are considering LASIK, you need to know what tests are necessary before LASIK, and whether you are a good candidate for LASIK.   You need to understand the procedure of LASIK step by step, for both the microkeratome and Blade free LASIK avatars. You also need to understand what precautions you need to take before the LASIK procedure, what you are likely to face during the LASIK procedure, and what you will have to undergo after the LASIK procedure.
