whats the alternative if lens is broken?

my unit is a ps2 slim 77006 ntsc-j, ive been playing darkcloud 2 again this past few days 100% working, loading was fast no crash or anything...but suddenly it hanged on me and just dont run anymore at times if i reset it goes to the playstation2 logo but does not load the game...or just wont load at all...my unit is modded since i play with games i burn on dvds. if the lens is dead what else can i do so i can still play with my console?

p.s. i know the disk is turning and lens is moving also i can see the laser dot when its trying to read the disk.
