How offen do micropscope lens's need cleaned?
Microscope lenses should be cleaned with lens paper before each use. This maximizes the clarity.
Can cataract lenses be removed to be cleaned?
If the lenses are embedded in the eye, no. These lenses are permanent, acting just like the cornea of the eye. They are implanted where the cornea would have been because...during the surgery...the original corneas were destroyed to make room for the lenses. If the lenses are external, they are like any contact lens. They fit over the cornea and need to be removed for regular cleaning. Consult your ophthalmologist concerning this procedure. The embedded lenses do not need to be cleaned because the body automatically cleans them just like it cleans the cornea. If you are experiencing any problem that makes you think that the lenses need to be cleaned, consult your surgeon. Frequently, there are conditions that affect vision that have nothing to do with the lenses. Discuss this immediately with your health care professional before there are further problems.
Will eye infection result if hands aren't clean when removing soft contact lenses?

Should I wear glasses or contact lenses?
This depends on how bad your vision is, if it is not super bad you can probably wear contact lenses rather than glasses. Also some people have dry or easily irratible eyes and therefore have a big problem with thier contacts. Finally make sure to check with your opthamologist about anything else that might be paticular to you. Hard contact lenses are typically more expensive than soft contact lenses because they are not disposable. Hard lenses are designed to be cleaned and reused and often last for more than a year. Hard lenses are typically reserved for special eye problems were soft lenses are not practical.
