1. An IOL compression device, comprising:
a housing having a proximal end and a distal end, and a track disposed on a first side of the housing;
a tapered IOL compression channel disposed within the housing and having a longitudinal axis extending from the proximal end to the distal end;
a slidable button movably coupled within the track, the slidable button axially slidable between a proximal position and a first distal position, the track having a longitudinal axis substantially aligned with and adjacent to the tapered IOL compression channel, the slidable button having:
a pad accessible to a user and adapted to receive an axial force; and
an IOL base towing post adapted to extend substantially perpendicular to the tapered IOL compression channel, the IOL base towing post having a first end coupled to the slidable button and a second end adapted to contact a distal inner edge of an IOL base when the IOL base is in the tapered IOL compression channel;
wherein in response to an axial movement of the slidable button toward the distal end of the housing:
the IOL base towing post is adapted to axially pull the IOL base through the tapered IOL compression channel toward the distal end of the housing; and
in response to contacting an interior surface of the tapered IOL compression channel, the IOL base is adapted to adopt a compressed configuration.
