Before the era of refractive cataract surgery, refractive misses weren’t much of a concern says Robert J. Weinstock, MD, of The Eye Institute of West Florida. “We didn’t promise spectacle independence, like we do today, so if there were refractive errors after cataract surgery we didn’t worry as much,” he explains. “Back then, if there was a significant refractive miss or if the IOL dislocated, requiring an IOL exchange, it felt like a huge failure.

Secondary lens implantation can remedy a variety of scenarios, from the wrong power lens having been implanted to a lens that’s creating problems within the eye such as UGH syndrome or one that’s decentered or dislocated.

Instead, surgeons must identify a different space for the replacement lens, and that new location depends on the eye’s anatomy after the first lens is removed.
