“…Suturing the iris to repair the angle recession due to the iris retraction to prevent pupillary capture by the IOL has been described. 9 The results indicated that the PI did not reduce iris uttering due to eye movements, however, it is assumed the PI prevented a reverse pupillary block by blocking a homeostatic backward movement of the iris. We believe that a simulation of uid dynamics can be reproduced using a computational model.…”

“…This is important because excessive iris movements can lead to a pupillary capture by the intraocular lens causing a reverse pupillary block, one of major complications after intrascleral xation and ciliary sulcus xation of an IOL. [9][10][11][12] Pupillary capture by the IOL can cause an increase of the intraocular pressure and mild eye pain and discomfort. In addition, the capture by the IOL can deform the pupil which can reduce the visual acuity by decreasing the depth of focus and increasing the ocular aberrations.…”

The iris fluttering after eye movements was quantified by anterior segment optical coherence tomography (AS-OCT) in 29 eyes that had undergone pars plana vitrectomy (PPV) and intrascleral fixation of an intraocular lens (IOL, ISF group) and 15 eyes with PPV and an IOL implantation into lens capsule (control group). The iris fluttering was recorded every 0.2 seconds by AS-OCT after the eye had moved from a temporal to the primary position (time 0). The iris height from the iris plane (line between the anterior chamber angles) were compared between the groups. The height of the nasal sector in the ISF group decreased to -0.68 ± 0.43 mm at 0 sec (P < 0.0001) and returned to -0.06 ± 0.23 mm at 0.2 sec (P = 0.14). The height of the nasal sector at 0 sec was significantly lower than that of control (-0.05 ± 0.09 mm, P < 0.0001). The height of the temporal sector increased to 0.45 ± 0.31 mm at 0 sec (P < 0.0001) and returned to -0.06 ± 0.18 mm at 0.2 sec (P = 0.15). The height of the temporal sector at 0 sec was significantly higher than that of the control (0.03 ± 0.06 mm, P < 0.0001). Large amplitude iris fluttering leading to reverse pupillary block can be detected and quantified by consecutive AS-OCT images.

“…We previously reported that repairing cyclodialysis could restore a normal iris plane. Moreover, separation of the iris and IOL could prevent pupillary capture of the IOL while retaining normal pupillary function [ 8 ].…”

“…However, none of these reported methods for preventing pupillary capture could repair any of the primary causes of iris retraction. Although we have previously reported that repairing cyclodialysis by suturing the iris could prevent pupillary capture [ 8 ], it had been still technically difficult. We have devised a novel technique for repairing iridodialysis by riveting with a double-flanged polypropylene suture [ 9 ].…”

Cyclodialysis causes intraocular lens (IOL) pupillary capture. It requires surgical repair to prevent this risk of IOL pupillary capture. However, since repairing cyclodialysis is often technically difficult, other methods such as barricading by suturing, pupilloplasty, and pars plana fixation of the IOL were preferred. We applied a double-flanged (riveting) technique for repairing cyclodialysis to prevent IOL pupillary capture following intrascleral fixation of the IOL. Cyclodialysis was surgically repaired by riveting with double-flanged 6-0 polypropylene sutures in 3 cases with no recurrence of pupillary capture during at least 12 months of follow-up. When pupillary capture is related to cyclodialysis, repairing cyclodialysis may help prevent pupillary capture after intrascleral fixation of the IOL. Riveting using a double-flanged 6-0 polypropylene suture could possibly make the procedure simpler and more efficient.

“…The flow of the aqueous and vitreous humor through the gap around the optics of the IOL during eye movements causes the iris to oscillate back and forth, i.e., flutter. This is important because excessive iris movements can lead to a pupillary capture by the intraocular lens, causing a reverse pupillary block, one of the major complications after intrascleral fixation and ciliary sulcus fixation of an IOL [ 9 , 10 , 11 , 12 ]. Pupillary capture by the IOL can cause an increase in intraocular pressure and mild eye pain and discomfort, called Uveitis-Glaucoma-Hyphema (UGH) syndrome.…”

Saccadic eye movements induce movements of the aqueous and vitreous humor and iris fluttering. To evaluate iris fluttering during eye movements, anterior segment optical coherence tomography (AS-OCT) was used in 29 eyes with pars plana vitrectomy (PPV) and intrascleral fixation of an intraocular lens (ISF group) and 15 eyes with PPV and an IOL implantation into lens capsular bag (control group). The height of the iris from the iris plane (the line between the anterior chamber angles) was compared every 0.2 s after the eye had moved from a temporal to the primary position (time 0). The height of the nasal iris in the ISF group decreased to −0.68 ± 0.43 mm at 0 s (p < 0.001) and returned to −0.06 ± 0.23 mm at 0.2 s. The height of the temporal iris increased to 0.45 ± 0.31 mm at 0 s (p < 0.001) and returned to −0.06 ± 0.18 mm at 0.2 s. The height of the nasal iris at 0 s in the ISF group was significantly lower, and that of the temporal iris was significantly higher than the control (−0.05 ± 0.09 mm, 0.03 ± 0.06 mm, p < 0.001, respectively). Iris fluttering can act as a check valve for aqueous and vitreous humor movements and can be quantified by consecutive AS-OCT images. Large amplitude iris fluttering in eyes with intrascleral fixation is important because it can lead to a reverse pupillary block.
