So, is it basically the standard rule that when you're replacing a natural lens, the artificial one gets implanted behind where it used to be?
To put it another way—if someone is looking to fix their nearsightedness by getting a Yahoo implant, do they actually leave the natural lens in place if it's still healthy? In that scenario, does the procedure just involve placing the new lens into the anterior chamber?
Generally speaking, provided there aren't any complications, an intraocular lens is placed in the posterior chamber.
It is also possible to place an intraocular lens in the posterior chamber alongside the natural lens—I believe companies like Alcon perform this—but one has to be careful that the lens and the implant don't touch, otherwise you risk developing cataracts.
They have specialized equipment to measure that specific gap between the lenses.
Ultimately, contact lenses remain a perfectly fine solution, so once cataracts eventually show up, that myopia can simply be corrected by adjusting the lens strength.
