This application is a continuation application of U.S. patent application Ser. No. 13/969,115 now U.S. Pat. No. 9,289,287, filed Aug. 16, 2013, which claims the benefits under 35 U.S.C. §119(e) of priority to U.S. Provisional Patent Application No. 61/830,491, filed Jun. 3, 2013, entitled “MODULAR INTRAOCULAR LENS DESIGNS AND METHODS,” each of which is incorporated herein by reference in its entirety. U.S. patent application Ser. No. 13/969,116 is also a continuation-in-part application of U.S. patent application Ser. No. 13/748,207 now U.S. Pat. No. 9,905,424, filed Jan. 23, 2013, entitled “MODULAR INTRAOCULAR LENS DESIGNS & METHODS,” which claims the benefits under 35 U.S.C. §119(e) of priority of U.S. Provisional Patent Application No. 61/589,981, filed on Jan. 24, 2012, entitled “LASER ETCHING OF IN SITU INTRAOCULAR LENS AND SUCCESSIVE SECONDARY LENS IMPLANTATION,” and of U.S. Provisional Patent Application No. 61/677,213, filed on Jul. 30, 2012, entitled “MODULAR INTRAOCULAR LENS DESIGNS & METHODS,” each of which is incorporated herein by reference in its entirety.
FIGS. 29A-29C show the base portion 55 of the modular IOL 290, and FIGS. 29D-29F show the lens portion 65 of the modular IOL 290. Specifically, FIG. 29A shows a front view of the base 55 having a body portion, FIG. 29B shows a cross-sectional view taken along line B-B in FIG. 29A, and FIG. 29C shows a perspective view of the base 55. FIG. 29D shows a front view of the lens 65, FIG. 29E shows a cross-sectional view taken along line E-E in FIG. 29D, and FIG. 29F shows a perspective view of the lens 65.
Recessed groove 292 includes a lower rim 291 and an upper rim 293. The upper rim 293 may have an inside diameter that is greater than the outside diameter of the lens 65 such that the lens 65 can rest inside the hole 57 of the base 55. All or a portion of the lower rim 291 may have an inside diameter that is less than the outside diameter of the lens 65 such that the lower rim 291 acts as a backstop for the lens 65 when placed in the hole 57 of the base 55. By way of example, not necessarily limitation, the upper rim 293 may have an inside diameter of about 6.0 mm, the lower rim 291 may have an inside diameter of about 5.5 mm, and the lens 65 may have a longitudinal dimension (including tabs 295 and 296) of about 7.125 mm, as shown in FIG. 29D. Further, the optical body portion 297 may have an outside diameter of about 5.8 mm, as also shown in FIG. 29D. Further, as shown in FIG. 29B, the base may include a thickness of about 0.615 mm. Also, the upper rim 293 may include a length of about 0.45 mm. The lower rim 291 may include an anterior surface having a length of about 0.55 mm and a posterior surface having a length of about 0.75 mm.
With specific reference to FIGS. 29D-29F, the lens 65 of the modular IOL 290 includes an optical body portion 297 (also referred to herein as “optic portion”) and one or more tabs 295 and 296. As shown in FIG. 29E, tab 296 may include a thickness of about 0.25 mm, and optic portion may include a thickness of about 0.78 mm. As shown, tab 295 is fixed, whereas tab 296 may be actuated. As an alternative, fixed tab 295 may be replaced with an actuatable tab (e.g., like tab 296). Fixed tab 295 may include a thru hole 298 so that a probe or similar device may be used to engage the hole 288 and manipulate the tab 295. Hole 298 may include a diameter of about 0.231 mm. Actuatable tab 296 may be actuated between a compressed position for delivery into the hole 57 of the base 55, and an uncompressed extended position (shown) for deployment into the groove 292 of the base 55, thus forming an interlocking connection between the base 55 and the lens 65.
