axis and / or z - axis ). further , the connecting portions 364 may twist or rotate about an axis along the length of the connecting portion , which may be about an axis that is substantially perpendicular to the longitudinal axis of the iol ( e . g . about an axis parallel to z - axis and / or x - axis ) and / or may be about an axis that is substantially parallel to the longitudinal axis of the iol ( e . g . about an axis parallel to y - axis ) in some cases . in some embodiments , each of the connecting portions 364 can be positioned adjacent the optic periphery and flexibly coupled thereto . the connecting portions 364 can be oriented such that their length extends along an axis substantially parallel to a transverse axis of the iol 100 ( e . g . along an axis parallel to the x - axis ) as shown in fig1 or substantially parallel to a longitudinal axis of the iol 100 as shown in fig2 . with continued reference to fig1 , as disclosed above , one or more connecting portions 364 can be oriented along an axis substantially parallel to a transverse axis of the iol 100 ( e . g . parallel to the x - axis ). the iol 100 can include two connecting portions 364 for securing each haptic 300 to the short appendage 362 and optic 200 . the connecting portions 364 can connect the haptic 300 to the short appendage 362 such that an elongate slot 366 is formed between the short appendage 362 and the haptic 300 . an elongate axis of the elongate slot 366 can be substantially perpendicular to the longitudinal axis of the iol through line a - a ( e . g . perpendicular to the y - axis ) in some embodiments . although not shown , the connecting portions 364 may be oriented along an axis that is less than or equal to about 5 °, 10 °, 15 ° 20 °, 25 °, 30 °, 35 °, 40 °, or 45 ° from the transverse axis of the iol ( e . g ., axis parallel to x - axis ). the elongate slot 366 is an aperture formed in the haptic 300 that extends laterally and parallel to the transverse direction ( e . g . parallel to the x - axis ). preferably , the slot 366 comprises an oval shape , but all shapes are specifically contemplated . as mentioned above , the slot 366 is adjacent the connecting portions distal to the optic 200 . preferably , the slot dimensions ranging from 0 . 1 to 0 . 5 mm in height and 2 . 0 to 5 . 0 mm in length . as shown in fig2 , one or more connecting portions or connecting bar 364 can be oriented or extend along an axis that is substantially parallel to a longitudinal axis of the aiol 100 ( e . g . along an axis parallel to the y - axis ). in some embodiments , the aiol 100 can include two connecting portions or bars 364 for securing each haptic 300 to the optic 200 although more or less are possible . for example , although not shown , each haptic 300 can be connected to the optic 200 by a single connecting portion 364 . although not shown , the connecting portions 364 may be oriented along an axis that is less than or equal to about 5 °, 10 °, 15 ° 20 °, 25 °, 30 °, 35 °, 40 °, or 45 ° from the longitudinal axis of the iol ( e . g ., axis parallel to y - axis ). the connecting portions 364 can connect the haptic 300 to the optic 200 such that an elongate slot is formed between the optic 200 and the haptic 300 . an elongate axis of the elongate slot can be substantially perpendicular to the longitudinal axis of the iol through line a - a ( e . g . parallel to the x - axis ). the connecting portions 364 couples the optic 200 to the haptic 300 and is preferably of the same material as the optic . likewise , in various embodiments , the connecting portions 364 may not include a hinge feature , for example , between the optic 200 or appendage 362 and the haptic 300 about which portions of the connecting portion bend like a hinge . example hinges or straps with hinge features are described in u . s . patent publication no . 2011 - 0313519 a1 , published dec . 22 , 2011 ( u . s . patent application ser . no . 13 / 017 , 189 ); u . s . patent publication no . 2011 - 0313524 a1 , published dec . 22 , 2011 ( u . s . patent application ser . no . 13 / 092 , 359 ); u . s . patent publication no . 2011 - 0313525 a1 , published dec . 22 , 2011 ( u . s . patent application ser . no . 13 / 111 , 599 ); and u . s . patent publication no . 2011 - 0313526 a1 , published dec . 22 , 2011 ( u . s . patent application ser . no . 13 / 155 , 327 ), incorporated herein by reference in their entireties . the connecting portions or bars 364 can extend lengthwise laterally ( as in fig1 ) or longitudinally ( as in fig2 ) between opposing paddles of the haptic along an axis either substantially parallel or substantially perpendicular to the longitudinal axis of the iol through line a - a . moreover , the connecting portions are in various embodiments integral to the haptic 300 at each of the lateral ends ( as shown in fig1 ) or at each of the end distal to the optic 200 ( as shown in fig2 ), and are preferably of the same flexible material as the haptic . however , the connecting portions 364 may also be of a different material than the haptic 300 , for example , such that the connecting portions are substantially more flexible than the haptic . in at least one embodiment , the connecting portions 364 may be from 0 . 1 to 1 . 5 mm in length . preferably , the connecting portion 364 has a square or circular cross - section , but other cross - sectional solid shapes are specifically contemplated . accordingly , in various embodiments , the cross - section has a width and height that are substantially equal and may be smaller than the length of the connecting portion or bar 364 . for example , the width of the cross - section perpendicular to the length of the connecting portion or bar 364 may be less than 1 . 5 , 1 . 4 , 1 . 3 , 1 . 2 , or 1 . 0 times the height of the cross - section or may be smaller and possible larger in some embodiments . similarly , the width of the cross - section perpendicular to the length of the connecting portion or bar 364 may be less than 2 . 0 , 1 . 5 , 1 . 2 , or 1 . 0 times the length of connecting portion or bar or may be smaller and possible larger in some embodiments . on insertion into the eye , the optic 200 and haptics 300 may be vaulted posteriorly . this effect is facilitated by the stretching , and potentially thinning , bending , and / or rotation of the connecting portions in response to the increase in pressure exerted by the capsular bag on the distal ends of the haptics . in at least one embodiment , the longitudinal length of the iol ( e . g ., from distal end to distal end , wherein the distal end is distal with respect to the optic 200 ) may be between approximately 9 . 0 - 11 . 0 mm , with the diameter as measured from the tips of the lateral finger projections with respect to the optic being between approximately 11 . 5 - 12 . 0 mm . the haptics 300 are in various embodiments between 3 . 0 - 6 . 0 mm wide and 0 . 20 - 0 . 75 mm thick , while the optic 200 may be approximately 5 . 0 mm in diameter and 1 . 0 mm thick at its center . in various embodiments the connecting portions or connecting bars 364 are thin and experience more thinning when stretched . without stretching , for example , the connecting portions or connecting bars 364 may be thin with respect to the optic 200 and the lens 100 . in certain embodiments , for example as shown in fig2 , the connecting portion or connecting bar 364 may have a width in the transverse direction ( e . g ., parallel to the x - axis ) less than 50 %, 40 %, 30 %, 20 %, 10 %, 5 % or less of the width or diameter of the optic 20 . similarly , the connecting portions or connecting bars 364 may have a thickness orthogonal to the transverse and longitudinal directions ( e . g ., parallel to the z - axis ) that is less than 50 %, 40 %, 30 %, 20 %, 10 %, 5 % or less of the diameter of the width or diameter of the optic 20 . the width and thicknesses may be greater than 0 . 5 % or 1 % of width or diameter of the optic 20 in some embodiments . the dimensions described above allow for adequate stretching . additionally , such widths may reduce the incidence of tearing when inserting the iol into the small opening made in the sclera or cornea of the eye . the iol is rolled to facilitate insertion and the resultant twisting can introduce shear forces on wider connections , which may cause tearing . having narrow widths reduces the shear force and permits twisting without tearing . the connecting portions or bars 364 such as shown in fig1 and 2 being thin permit stretching . in various embodiments , the connecting portions or bars 364 stretch and thereby increase their length by at least 0 . 5 , 1 . 0 , 1 . 5 , or 2 . 0 times of their length or more . conditional language , such as “ can ,” “ could ,” “ might ,” or “ may ,” unless specifically stated otherwise , or otherwise understood within the context as used , is generally intended to convey that certain embodiments include , while other embodiments do not include , certain features , elements , and / or steps . thus , such conditional language is not generally intended to imply that features , elements , and / or steps are in any way required for one or more embodiments or that one or more embodiments necessarily include logic for deciding , with or without user input or prompting , whether these features , elements , and / or steps are included or are to be performed in any particular embodiment . the terms “ approximately ,” “ about ,” and “ substantially ” as used herein represent an amount close to the stated amount that still performs a desired function or achieves a desired result . for example , the terms “ approximately ”, “ about ”, and “ substantially ” may refer to an amount that is within less than 10 % of , within less than 5 % of , within less than 1 % of , within less than 0 . 1 % of , and within less than 0 . 01 % of the stated amount . some embodiments have been described in connection with the accompanying drawings . however , it should be understood that the figures are not drawn to scale . distances , angles , etc . are merely illustrative and do not necessarily bear an exact relationship to actual dimensions and layout of the devices illustrated . components can be added , removed , and / or rearranged . further , the disclosure herein of any particular feature , aspect , method , property , characteristic , quality , attribute , element , or the like in connection with various embodiments can be used in all other embodiments set forth herein . additionally , it will be recognized that any methods described herein may be practiced using any device suitable for performing the recited steps . the embodiments described in detail above are considered novel over the prior art of record and are considered critical to the operation of at least one aspect of the invention and to the achievement of the above -
