“…Fourteen eyes (28%) had mild sphincter tears that did not require pupilloplasty. No complication related to the use of the APX such as hyphema, iridodialysis, or Descemet membrane detachment were noted in this series [57] (video: https://www.aao.org/clinical-video/ apx-novel-pupil-expander and https://www.youtube.com/watch?v=3OvxfcjqrZQ).…”

“…The APX provide a square pupil very similar to the four iris hooks; however, the number of incisions necessary to achieve pupil expansion is limited to two rather than four. Among potential advantages over expansion ring devices, no intracameral maneuvers are needed and the smaller profile might make this device more suitable for crowded anterior chamber [29,57,58]. A recent study has reported the outcomes of the first 50 consecutive eyes where APX-200 was used to enlarge small pupils, with mean preoperative pupil diameter of 3.7 mm.…”

Purpose of reviewCataract surgery in the setting of small pupil represent a major challenge and it is associated with a higher risk of complications. When pharmacologic pupil dilation fails, mechanical pupil expansion devices are needed to obtain and maintain sufficient intraoperative mydriasis. The purpose of this review is to assess the pupil expansion devices currently available.Recent findingsA variety of pupil expansion devices are offered on the market. They differ for design, material, shape, size, cost, and easiness of insertion/removal, nonetheless they all seem to be effective in improving the pupil size and easing the cataract surgery.SummaryMechanical pupil expansion can be effectively achieved with a variety of devices, which are well tolerated and can facilitate cataract surgery in the setting of poor mydriasis.

“…Therefore, additional post-operative complications may be induced by iridoschisis, for example, the sphincter muscle can be damaged, and the pigmented iris epithelium can be exposed, thereby inducing symptomatic photic phenomena [19][20][21][22] . To protect the iris, several pupil expanding devices are conducive to the surgery, including iris retractors, flexible iris hooks, and pupil expanders [16,[23][24][25][26] . Among of which, iris hooks is commonly available in most operating room, while many surgeons habitually use the device for inadequate pupil dilation [27][28] .…”

AIM: To introduce a new technique for iridoschisis management during phacoemulsification: “capsule drape wrap”. METHODS: “Capsule drape wrap” technique was used for an 80-year-old man with idiopathic iridoschisis in the right eye during phacoemulsification. The inserted flexible nylon iris hooks to hold anterior capsule in place, the margin of the anterior capsule could act as drape wrap, tracking the fibrillary iris strands firmly from free floating and stabilizing the capsular bags simultaneously. RESULTS: The eye with iridoschisis was successfully treated. Iris fibrils remained immobile during the procedure, and despite the severity of iridoschisis, there were no intraoperative complications such as tear of the iris, hyphema, iris prolapse, loss of mydriasis, or rupture of the posterior lens capsule during phacoemulsification. The best-corrected visual acuity was increased by 0.1 (logMAR) 6mo after the surgery. CONCLUSION: “Capsule drape wrap” for iridoschisis is easily manageable, prevents further disruption to the loose iris fibers and ensures the stability of capsule–iris complex simultaneously, consequently minimizing the risk of surgical complications in phacoemulsification.

“…Iris hooks are more cumbersome, tedious, and timeconsuming [8,9]. With the availability of devices like the Malyugin ring, Canabrava ring, Assia pupil expander, B-Hex, I ring, and Iris speculum, among others, the threshold for using pupil augmentation rings has come down [7,[10][11][12].…”
