I think you mean phaco. It is actually short for phacoemulsification which is a type of cataract surgery
where we emulsify the cataract
in the eye. It requires a small incision. Depending upon the type of lens you opt the incision given will vary form 2. 6mm to 3. 2mm. Mics is a variant of phaco where the incision will be 2. 2mm. In femto the incisions are given by laser
and the cataract will be softened by laser but the rest of the procedure will be done by phaco itself. If you want to opt for intaocular lenses which will give both clarity for near and distant vision then you will have to go for multi-focal iols. It has both advantages and disadvantages (like glare etc.) discuss it with the surgeon itself.
