Abstract: A plasmin activity reducing agent for use in reducing visual refractive regression in an eye after occurrence of a wide area superficial ablation wound of the anterior corneal surface, by topically administering to the eye said plasmin activity reducing agent, e.g., a plasmin inhibitor such as aprotinin. Such refractive regression often appears in patients that undergo surgical procedures that create such a wound in an attempt to improve the visual acuity of the patient. The invention also relates to a method of preoperatively testing a tear sample from a potential patient for the risk of postoperative visual regression resulting from a procedure that creates such a wide area superficial ablation wound on the cornea, by determining the level of proteolytic agent in the sample as an indicator of potential postoperative visual regression.

Abstract: Apparatus and methods are disclosed for reprofiling a surface (e.g., the cornea of the eye) by ablation. The apparatus is positioned between a source of ablative radiation and a surface so that the exposure area of the surface to which the radiation is delivered may be varied. In one embodiment, a masking means having apertures of predefined shapes is provided to selectively pass a portion of the radiation and drive means is employed to move the masking means across the beam of radiation in two different directions, thereby effecting two patterns of ablation at the surface, such that the cumulative effect of these two patterns is the selective ablation and reshaping of the surface.

Abstract: Apparatus (10) and methods are disclosed for astigmatically ablating surfaces in order to impart new profiles and curvatures to such surfaces. A laser means (12), e.g., a rapidly pulsed laser radiation source, is aligned with a surface (24) to provide photoablative pulses of energy along an optical path to a target region on the surface. A light restricting means (14), such as an adjustable iris or profiled mask, is disposed within the optical path to spatially control the extent of the laser radiation striking the target surface. The light restricting means is adapted to permit orientation (e.g., tilting) in various planes relative to the optical path in order to modify the symmetry of the laser beam, e.g., from a circular shape to an elliptical shape, and thereby provide astigmatic ablation of the surface in a single step.

Abstract: Methods and apparatus are disclosed for the correction of presbyopia by reprofiling the cornea to create at least one region having a different focal point, and thereby assist the eye in accommodating for close-viewing conditions. According to the invention, at least one region of different curvature is created by photoablation of the cornea to permit the eye to accommodate for near objects. This "add" region is preferably located near the center of the optical zone and preferably within Bowman's membrane or the adjacent upper portions of the stroma, which lies directly below Bowman's membrane. Apparatus is disclosed, including a laser means and a beam-shaping means, disposed between the laser means and the surface of the cornea, which imposes a defined ablation profile upon the cornea. The system can also include a feedback control means for measuring the effectiveness of the laser during operation and for controlling the laser. The beam-shaping means can include either an aperture e.g., a beam-shaping stop means alone or in combination with a beam-shaping window, or a mask which is photodecomposable or otherwise graded in its absorptive capacity to present a predefined profile of resistance to the laser radiation.

Abstract: A method and device for lifting the epithelium (1) from a selected area of the eye using a jet assembly (8) constructed to produce an epithelium-detaching fluid jet capable of detaching epithelium that is biologically attached to an underlying structure of the eye. The jet assembly directs the jet having a substantially tangential force to the eye surface in order to separate and remove the epithelium from the relatively hard underlying layer. The device shown also has an epithelium support structure (9) for supporting and maintaining the structural integrity of the lifted epithelium. The lifted epithelium can be biologically preserved and repositioned on the exposed surface of the eye.

Abstract: Apparatus and methods are disclosed for distributing and delivering laser radiation with substantially uniform intensity to multi-spatial locations. Laser radiation (14) is directed into a fiber optic waveguide (20) which homogenizes the spatial intensity of the laser beam via mode-mixing. The laser radiation is then coupled from the mode-mixing waveguide to multiple distribution fibers (26) that are terminated at desired spatial locations, e.g., at the distal end of a surgical tool (45). The output from each of the multiple distribution fibers is laser radiation of substantially uniform intensity.
