Posterior chamber intraocular lenses in a series of 75 autopsy eyes Part III: Correlation of positioning holes and optic edges with the pupillary aperture and visual axis

Abstract: The possibility that undesirable visual complications such as glare, halo, monocular diplopia, or other visual aberrations can result from the presence of posterior chamber lens optic edges or such lens elements as positioning holes or loop-optic junctions within the pupillary aperture has received little attention. There is recent clinical evidence that these phenomena may be clinically significant. In a series of 75 autopsy eyes with posterior chamber intraocular lenses, we have observed that in 71% of cases… Show more

“…44 In this regard, using an IOL with an optic size larger than the usually accepted 6 mm size has gained substantial support over the past three years, increasing from 21% in 1985 to 49% in 1987.45 Moreover, an IOL with positioning holes outside the optic on tabs was preferred by 55% of ophthalmologist respondents, while 35% wanted total elimination of the positioning This latter finding represents an increase from 7% in 1985 to the current level. If a 7 mm optic without positioning holes is compared to a 6 mm optic without holes, the surface area is increased by over 35%.…”

“…[10][11][12][13][14] It has been suggested that IOL-capsule adhesion is crucial to IOL stability, including tilt and decentration, after surgery. [15][16][17] In our previous study, we found that PPCCC resulted in earlier IOL optic-posterior capsule adhesion and better axial stability with implantation of 1-piece 360-degree square-edged hydrophobic IOL. 13 At 1 week postoperatively, 71.74% of eyes in the PPCCC group were observed to have complete adhesion between IOL optic and posterior capsule vs 34.78% in the control group.…”

“…With the introduction of continuous curvilinear capsu-lorhexis (CCC), in-the-bag haptic fixation has been re p o r ted to be one of the major factors in reducing the two most f requent long-term complications of extracapsular cataract extraction with PC-IOL implantation: IOL decentration (5)(6)(7) and posterior capsule opacification (PCO) (8)(9)(10)(11)(12)(13)(14)(15).…”
