20100094199 | System and method for modulated surgical procedure irrigation and aspiration - A method and apparatus for performing modulated fluid delivery and aspiration during a surgical procedure such as phacoemulsification is provided. The method and apparatus include delivering fluid and/or aspirating fluid in a modulated or pulsed manner during a surgical procedure, including applying fluid and/or aspirating fluid in connection with ultrasonic energy at a level and for a time period sufficient to induce transient cavitation. Fluid may be applied and/or aspirated at a timing sequence and duty cycle similar to or different from application of ultrasonic energy delivery. | 04-15-2010 |
20110029074 | FIXATION OF OPHTHALMIC IMPLANTS - An ophthalmic device for implantation into a capsular bag of an eye includes an adhesive or adherent that adheres to an eye at certain temperatures or other physical conditions, but has little or no adherence at other temperatures. The ophthalmic device may be an accommodating intraocular lens including an adjustable optic body and a support structure. The support structure includes an outer structure, an intermediate structure, and an adhesive or adherent material disposed over at least a portion of the support structure. The intermediate structure is located between, and connected to, the outer structure and the optic body. The outer structure has an outer face configured for engaging a capsular bag of an eye. The outer face includes an equatorial region, with anterior and posterior regions disposed on opposite sides of the equatorial region. Under a predetermined condition, the posterior region has an adhesion that is greater than an adhesion of the anterior region. | 02-03-2011 |
20110054601 | FIXATION OF OPTHALMIC IMPLANTS - An accommodating intraocular lens (aIOL) is disclosed, with an optic that changes shape in response to an ocular force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. A surface adherent improves the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. One way to enhance force transfer is to provide a surface layer of an adhesive to the haptic and/or optic, for instance a reversible bioadhesive material. Or, portions of the exterior surface of the IOL may have microfibers thereon that mimic the adhesive properties of Gecko feet. Another aspect is application of a reversible bioadhesive material to the interior of the empty capsular bag prior to introduction of an injectable polymer IOL. | 03-03-2011 |
