Abstract
The present invention relates to a visual simulating system for correcting a binocular vision high order aberration. The system is composed of two sets of adaptive optical beacons (1), a beam-expanding system (2), a reflecting mirror (3), a beam splitting mirror (4), a reflecting mirror (5), human eyes (6), a light beam matching telescope (7), a wavefront correcting device (8), a reflecting mirror (9), a light beam matching telescope (10), a beam splitting mirror (11), a Hartmann wavefront sensor (12), a computer (13), a high-voltage amplifier (14), a reflecting mirror (15), an imaging optical system (16), a display (17) of a visual discriminating rate and a computer (18). A binocular stereoscopic vision effect after an operation or after the high order aberration is corrected can be sensed by a patient by the instrument in the making process of an operating scheme or individual contact lenses. The operation scheme or a design scheme can be mutually discussed by the patient and doctors, or the modification and the optimization of parameters can be realized before the individual contact lenses are made. Meanwhile, the relationship between objective measuring data and visual subjective senses is established so that the preoperative optimization of a nonreversible operation scheme becomes possible.
Description
Affiliated technical field
The present invention relates to a kind of binocular stereopsis correction for higher order aberrations visual simulation system, be a kind of be used for before the customized human eye higher order aberratons operation redressment or the configuration of customized human eye higher order aberratons contact lens before, the optical instrument of emulation human eye postoperative or contact lens configuration back stereoscopic visual effect.
Background technology
Since the scientist of the former Soviet Union invention radial keratotomy seventies in last century (RadialKeratotomy-RK) is corrected defects of vision, progress along with laser technology, photoelectric technology, the nineties having occurred excimer laser cornea cuts and melts art (Photorefractive Keratertomy-PRK), the Laser in Situ Keratomileusis that the later stage nineties grows up (Laser in SituKeratomileusis-LASIK), these technology all develop into for outpatient operation in recent years.These operations focus on the retina parallel rays by the curvature of scalpel, laser cutting cornea tissue, change anterior corneal surface again, thereby reach the purpose of correction of refractive errors.
Along with the appearance of aberration of human eye accurate measuring technique, " personalization " cornea refractive surgery of wave aberration guiding becomes possibility.The personalized cutting of the cornea of so-called wave front aberration guiding is meant the wave front aberration of measuring patient's eye with wavefront analyzer, and data are computer as calculated, and making needs corrigent operation plan, carries out operation by small light spot flying-spot scanner laser system in the LASI K operation.That is according to the optical characteristics and the anatomical features of Different Individual uniqueness, by various wave aberrations, as spherical aberration, astigmatism, coma and the cutting of aspheric surface error, correct individual aberration of human eye, and reduce the higher order aberratons that operation brings, thereby improve human eye retina's image quality.This mode can make the patient obtain than the normal person better " extraordinary vision " in theory.
David Williams laboratory was once done corresponding research experiment with regard to the higher order aberratons of proofreading and correct human eye, the subjective picture element that higher order aberrations helps to improve human eye is fallen in the proof school, this experimental system is primarily characterized in that Shack-Hartmann wavefront sensor (" VisualPerformance after correcting the monochromatic and chromaticaberrations of the eye " Geun-Young Yoon and David R.Williams of the measurement employing microlens structure of human eye aberration, J.Opt.Soc.Am.A/Vol.19, No.2/February).
In actual applications, also there is following several problem in personalized LASI K operation:
(1) operation is irreversible, and patient's post-operative cornea is very thin, even if accurately measured the residual aberration of postoperative, also can't be corrected by performing the operation once more;
(2) difference of objective personalization and vision subjective feeling.The formulation of operation cutting scheme is fully based on the aberration measurement data of physics, but aberration to image quality particularly people's subjective vision feel to have duality.Even eliminated all aberrations by operation sometimes, patient's subjective sensation is not necessarily best, not necessarily reaches the most satisfied visual effect of patient; Help to improve patient's subjective sensation and comfort level and suitably keep some aberration, or help to improve some specific visual function;
(3) factors such as automatic healing function of lasik surgery cutting precision, partial center cutting and cornea tissue wound make postoperative effect have unpredictability and non-confirmability to a certain degree.
So in the operation plan formulation process, how to consider the elimination of aberration, which aberration should be eliminated, aberration is to what extent eliminated, how to consider operation cutting error, the inclined to one side error in center, how to set up relation between objective aberration compensation and patient's subjective feeling or the like problem, all need a kind of instrument to help the result of implementation of sham operated scheme in advance, be convenient to reduce risk, reach surgical effect near expection.
In addition, configuration customized human eye higher order aberratons contact lens needs prior wave front aberration with wavefront analyzer measurement patient eye, and data machine as calculated are processed into control data, in order to formulate the mask scheme of contact lens, make individualized contact lenses through etching and exposure program again.This process cost of manufacture is more much higher than common spectacles, if the prior simulated eye mirror design of energy makes the patient experience it to the subjective rectification effect that human eye produces, will help improving the success rate of making, thereby reduce cost.
Except above-mentioned application purpose, objective evaluation patient's visual performance also needs to satisfy the stereoscopic function of eyes, and simple eye visual effect can not be represented the subjective vision effect of human eye fully.
Summary of the invention
Technology of the present invention is dealt with problems: a kind of binocular stereopsis correction for higher order aberrations visual simulation system is provided, make the patient in the formulation process of operation plan or individualized contact lenses, just can experience binocular stereo vision effect after postoperative or the correction for higher order aberrations by this instrument, make patient and doctor jointly operation plan is discussed or design becomes possibility, perhaps before individualized contact lenses is made, realize the modification optimization of parameter.The doctor also can use this instrument, various errors in the analogue simulation operation to the influence of patient's postoperative vision to optimize surgical parameters, set up the relation between objective measurement data and vision subjective feeling simultaneously, make preceding optimization of irreversible operation plan art become possibility.
