Methods of manufacturing and implanting corneal inlays, such as small diameter corneal inlays, are provided. The methods include manufacturing an implant body to have a meniscus shape with a small diameter and an index of refraction, and implanting the implant body in a corneal bed of a cornea. The inlays cause a change in an anterior surface of the cornea after implantation due to the implant body.

Small diameter corneal inlays

Methods of manufacturing a corneal implant that include creating an implant body that has a meniscus shape, a diameter of approximately 2.5 mm or less, and an index of refraction of 1.376. The implant body can further have a central thickness and an outer edge thickness.

Small diameter corneal inlay methods

Provided herein are small diameter inlays for correcting vision impairments by altering the shape of the anterior corneal surface. In an embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an 'effective' zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the 'effect' zone. In another embodiment, small diameter inlays are provided that induce effective optical zones on the anterior corneal surface that are much larger in diameter than the inlays. The increase in the effective optical zone, due at least in part to a draping effect, allows an inlay to produce a much larger clinical effect on a patient's vision than the diameter of the inlay.

Method of using small diameter intracorneal inlays to treat visual impairment

A transom plate for small fishing boats which simultaneously adjusts vertical displacement and trim of the outboard motor. The transom plate is adapted particularly for smaller fishing boats which must operate under widely varying loads and speeds, and which often encounter extremely shallow water. The plate comprises a rigid transom frame adapted to be clamped to the transom, and a motor bracket slidably movably coupled to the frame. Movement of the motor bracket relative to the transom frame is facilitated by a power cylinder preferably controlled from within the boat. The cylinder is pivotally coupled between the transom frame and the motor bracket, being secured and centered by L-brackets. Special follower slots are defined through each side of the jack to define a path of movement for displacement of the motor bracket relative to the transom frame. A generally vertically oriented slot is paired with a generally inclined follower slot on each side of the plate. Vertical displacement of the motor bracket results in simultaneous trimming of the motor.

An improvement for grand piano actions reduces unwanted friction between the repetition lever and the hammer shank. The conventional grand piano knuckle is replaced by a lever disposed generally parallel to the repetition lever and pivotally secured thereto at one end. An adjustable spring provides a force biasing the lever away from the repetition lever. A travel limit adjusts the maximum pivotal excursion of the lever relative to the repetition lever. At the opposite end of the lever, a centrally pivoted platform structure is pivotally secured. The structure includes a surface which engages the hammer shank and at least one brake surface which engages the repetition lever.
