摘要： A subjective refraction technique uses a plane wave light source including substantially a point as a viewing target. The refraction method provide for a number of distinct identifiable end points. By finding such end points the process leads to an aberration-corrected vision. A defocus corrector assembly (DCA) includes a lens that is moveable along an optical axis between a patient's eye and the point light source for adjusting defocus power until the patient indicates that the blurry image has become a relatively focused line image. An astigmatism corrector assembly (ACA) which is capable of continuously variable in its amplitude is provided including a pair of astigmatism plates for adjusting astigmatism power and axis angle. The ACA is adjusted until the patient indicates that the line image has become a substantially round image. A reference marker provides displayed items including a sweep line overlapping at the point source and having an orientation which is adjustable. The patient may subjectively control the sweep angle of the sweep line and indicate that the sweep line is aligned with the sharp line image of the point source, thereby providing axis angle data of astigmatism errors of the patient's eye.

摘要： An apparatus for determining spherical and cylinder components of subjective refraction of a patient's vision includes a wavefront measurement device that can produce a measure of quality of vision in a return beam from the patient's eye viewing a target through a corrective test lens in the apparatus. The corrective lenses may be varied and a plurality of measurements of quality of vision may be obtained and analyzed to determine the spherical and cylinder components. Accordingly, the eye examiner may conduct a refraction examination without a subjective response from the patient.

摘要： Optical elements are made using micro-jet printing methods to precisely control the type, position and amount of polymer deposited onto a substrate. In preferred embodiments, the proportions of two or more different polymer compositions are varied over the course of the deposition process to deposit adjoining polymer pixels in the form of a film on the substrate surface. The optical properties of each adjoining polymer pixel can be selected to provide a predetermined optical property, including a specific value of index of refraction. Preferably, the film has a radially non-monotonic refractive index profile and/or an angularly non-monotonic refractive index profile.

摘要： A laser-based method and apparatus for corneal surgery. The present invention is intended to be applied primarily to ablate organic materials, and human cornea in particular. The invention uses a laser source which has the characteristics of providing a shallow ablation depth (0.2 microns or less per laser pulse), and a low ablation energy density threshold (less than or equal to about 10 mJ/cm2), to achieve optically smooth ablated corneal surfaces. The preferred laser includes a laser emitting approximately 100-50,000 laser pulses per second, with a wavelength of about 198-300 nm and a pulse duration of about 1-5,000 picoseconds. Each laser pulse is directed by a highly controllable laser scanning system. Described is a method of distributing laser pulses and the energy deposited on a target surface such that surface roughness is controlled within a specific range. Included is a laser beam intensity monitor and a beam intensity adjustment means, such that constant energy level is maintained throughout an operation. Eye movement during an operation is corrected for by a corresponding compensation in the location of the surgical beam. Beam operation is terminated if the laser parameters or the eye positioning is outside of a predetermined tolerable range. The surgical system can be used to perform surgical procedures including removal of corneal scar, making incisions, cornea transplants, and to correct myopia, hyperopia, astigmatism, and other corneal surface profile defects.

摘要： A laser-based method and apparatus for corneal and intraocular surgery. The preferred method of performing a surface ablation of cornea tissue or other organic materials uses a laser source which has the characteristics of providing a shallow ablation depth or region (about 0.2 .mu.m to about 5.0 .mu.m), a low ablation energy density threshold (about 0.2 to 5 .mu.J/(10 .mu.m).sup.2), and extremely short laser pulses (having a duration of about 0.01 picoseconds to about 2 picoseconds per pulse) to achieve precise control of tissue removal. The laser beam cross-sectional area is preferably about 10 .mu.m in diameter. The preferred laser system includes a broad gain bandwidth laser, such as Ti.sub.3 Al.sub.2 O.sub.3, Cr:LiSrAlF.sub.6, Nd:YLF, or similar lasers, with a preferred wavelength of about 830 nm, which is generally transmissive in eye tissue. Various surgical procedures can be performed to correct refractive errors or to treat eye diseases. The invention can be used to excise or photoablate regions within the cornea, capsule, lens, vitreoretinal membrane, and other structures within the eye. The invention provides an improved method of eye surgery which has accurate control of tissue removal, flexibility of ablating tissue at any desired location with predetermined ablation depth, an optically smooth finished surface after the surgery, and a gentle surgical beam for laser ablation action.
