Abstract: An adjustable ocular insert to be implanted during refractive cataract surgery and clear (human) crystalline lens refractive surgery and adjusted post-surgically. The implant comprises relatively soft but compressible and resilient base annulus designed to fit in the lens capsule and keep the lens capsule open. Alternatively the annulus may be placed in the anterior or posterior chamber. The annulus includes a pair of opposed haptics for secure positioning within the appropriate chamber. A rotatable annular lens member having external threads is threadedly engaged in the annulus. The lens member is rotated to move the lens forward or backward so to adjust and fine tune the refractive power and focusing for hyperopia, myopia and astigmatism. The intraocular implant has a power range of approximately +3 0 -3 diopters.

Abstract: An adjustable ocular IOL/insert to be implanted during refractive cataract surgery and clear (human) crystalline lens refractive surgery and adjusted post-surgically. The implant comprises relatively soft but compressible and resilient base annulus designed to fit in the lens capsule and keep the lens capsule open. Alternatively the annulus may be placed in the anterior or posterior chamber. There is a second concentric annulus removably seated in the outer annulus. The second annulus has a threaded inner surface. A rotatable annular lens mount, bearing an appropriate lens, is threadedly engaged in the second annulus. The lens mount is rotated to move the lens forward or backward so to adjust and fine tune the refractive power and focusing for hyperopia, myopia and astigmatism. The intraocular implant has a power range of approximately +3.rarw.0.fwdarw.-3 diopters.
