A device to be inserted within a lens capsule during ocular surgery to contain fluids, including therapeutic and optical materials, used for irrigation within the capsule is provided. The device includes a deformable membrane within a ring. The ring may include flanges that increase sealing area between the ring and the posterior surface of an anterior capsule. One or more ports are provided for irrigation within the capsule. Reduced pressure in an area around the periphery of the membrane may be used for forming a sealing area between the device and the posterior surface of the capsule. Method for inserting the device into the capsule and performing irrigation or aspiration for polishing and for deforming the lens capsule is provided. The device may be placed in an eye for permanent isolation of fluids-within the lens capsule from tissue and fluids outside the capsule.

An economical computer-controlled non-invasive laser apparatus and method to perform anterior segment surgery in an eye are disclosed. The laser source may include a pumping laser, a Nd:YAG laser cavity gain media, a stimulated Raman converter crystal, intracavity beam diameter-reducing optics, and an intracavity Q-switching crystal. The laser pulses have a selected wavelength for anterior segment surgery. A laser pulse delivery and treatment control mechanism and method for the practicing surgeon are also provided. The laser pulses and delivery system may be used in anterior segment surgery for cataracts, where the laser pulses may be used to form the capsulotomy, to form the corneal incision or to disintegrate contents of the capsule before removal. The laser and delivery system may also the used to treat a capsule and lens for correcting or preventing presbyopia and to treat a cornea to correct visual deficiencies in an eye.

This invention relates to an improved procedure for polishing the interior of the lens capsule after the lens is removed. The procedure includes removing the phacoemulsification instrument from the eye after the lens and cortex material have been removed and then placing a novel sonic tip over or within the needle portion of the instrument. The tip portion of the instrument is then reinserted into the lens capsule with a lower ultrasonic energy level. The sonic tip is then placed in close proximity or in direct contact with the interior surface of the lens capsule to remove any remaining small particles of the cortex or other cells.

An apparatus is provided for decreasing or eliminating flow of fluid between a probe and an incision during surgical procedures. The apparatus may comprise a deformable layer on the probe. The deformable layer may be comprised of a polymer foam, which may be covered with a surface layer. In another embodiment, baffles on a base layer are provided. The deformable layer or baffles may be on a slidable base surrounding the probe.
