摘要:
An intraocular lens device that includes an intraocular lens optics that provides at least two powers of magnification one being near vision power and the other being distance vision power. The lens optics has surface modulations that are responsible for providing the near vision power. The zone structure provides an add power of over 6 diopters. The add power indicative of an extent that the near vision focusing power is greater than the distance vision focusing power.
摘要:
Intraocular lens implant that includes a lens optic and lens haptics configured to maintain a preoperative position of the posterior lens capsule after cataract removal and insertion of a lens implant. The lens haptics have proximal and distal portions, with the distal portions lying in a common plane and the lens optic extending in a lens optic plane. The distance between the planes may be at least substantially the same dimension as or larger than a shift distance that the posterior lens capsule would otherwise traverse between its normal anatomical location and its shifted anatomical location where it not constrained. The shifted anatomical location arises naturally after both removal of cataract lens material and removal of a portion of an anterior capsule.
摘要:
An infusion sleeve of an ultrasonic vibrating needle. The sleeve is collapsible and serrated or scalloped at a distal end. Fluid flows through a passage between the needle and the infusion sleeve in a direction from the proximal end of the sleeve to a distal end of the sleeve. Upon reaching the distal end, the fluid emerges by flowing across valley formations that are between peak formations of the distal end of the infusion sleeve. The peak formations abut the exterior of the incision so that the fluid flow cools tissue at the incision and the needle.
