FIG. 4 , which is a simplified sectional illustration of a field of view widening telescopic implant constructed and operative in accordance with a preferred embodiment of the present invention. The embodiment ofFig. 4 can be employed in any of the operational contexts shown inFIGS. 1-3 with suitable selection of lenses. As seen inFIG. 4 , the implant preferably comprises animplant body 100, which is supported byhaptics 102 via ahaptic mounting structure 104. Theimplant body 100 typically comprises mutually sealed forward and rearwardcylindrical housing portions cylindrical portion 106. - Typically, the
implant body 100 is formed of glass housing portions, which are sealed by glass laser welding. - Disposed rearwardly of the
forward window 110 in forwardcylindrical portion 106 is anegative lens 112. Fixed tonegative lens 112 as a doublet is amagnificationl lens 114, which resides partially in the forwardcylindrical housing portion 106 and partially in the rearwardcylindrical housing portion 108. Disposed rearwvardly of themagnification lens 114 is apositive lens 116, which is mounted in sealing engagement with the rearwardcylindrical housing portion 108 ofimplant body 100 and defines a rearward facing window. - Preferably, the
negative lens 112 and thepositive lens 116 include refractive and diffractive optical elements. - Typically, the
negative lens 112 and thepositive lens 116 are coated with optical coatings. - It is an important feature of the present invention that the interior of the
implant body 100 is sealed from the exterior thereof, so as to prevent liquids or vapors from entering the implant. It is also an important feature of the present invention that three air gaps, designated byreference numerals contact point 126 betweenlenses peripheral contact area 128 betweenlenses axis 130 is also of importance to maintain desired focus. - In accordance with a preferred embodiment of the present invention, a resilient 0-
