“…However most of the mentioned instrument wasn't widely available. (9) Iris retractor was initially used to stabilize lens on patient with pseudoexfoliatife syndrome. Phacomeulsification with use of iris retractor was reported safe procedure to be done in subluxated lens.…”

“…Combination of 4-5 iris hooks and CTR ensures centration of Phacoemulsification with combination of CTR and Iris Hook in Subluxated Cataract 10 capsular bag and capsular expansion in 360 O that provides "in the bag" IOL implantation option. (9,10,11) The implantation of CTR immediately after capsulorexis is completed ensures higher safety of remaining procedures because of equal distribution of force by the ring and stabilization of the capsular bag. However the removal of lens material that trapped under capsular ring became difficult and sometimes retained some lens material that stuck.…”

Purpose: To report a management of challenging case of phacoemulsification in cataract with subluxated lens. Methods: A 63 male patient referred to RSDS with secondary lens induced glaucoma and cataract with subluxation around 210O on left eye. Patient was planned to undergone Phacoemulsification with combination of CTR and Iris Hook for lens extraction. Result: Postoperative result is satisfactory with minimal corneal edema. After 6 weeks of follow-up uncorrected vision is 5/8 with correction of S+0.25 became 5/5 and IOP is stable at 17 mmHg and the IOL was in placed in the bag and well centered. Conclusion: Phacoemulsification with iris hooks combined with CTR is one of surgery option that is safe and widely attainable for cataract with subluxated lens.

“…An auxiliary iris hook [2][3][4][5] or capsular hook is used in surgical repair of crystalline lens dislocation or subluxation. 7 The iris hook was the earliest internationally applied tool that was used in PHACO to expand the size of the pupil 8 and divide it to create flexible 9 and rigid iris retractors. 10 The earliest iris hook was developed by Hohwig 11 and was applied to treatment of lens subluxation by Merriam and Zheng.…”

ObjectiveTo observe the treatment effects of chop hook-assisted phacoemulsification surgery in patients with crystalline lens dislocation.MethodsThirty-seven eyes with cataracts and crystalline lens dislocations underwent cataract surgery. An L-shaped chop hook was introduced into the anterior chamber, and the tip was pushed or pulled to the centre of the anterior capsular edge of the zonular dialysis during the cataract operation. Postoperative follow-up was conducted for ≥ 1 month.ResultsAll patients’ postoperative visual abilities improved except one patient with glaucoma. One patient who underwent −5D intraocular lens implantation exhibited vision of 1/50. Visual acuity was less than 6/20 in 6 eyes, 6/20 to 10/20 in 7 eyes, and greater than 10/20 in 22 eyes.Conclusions L-shaped chop hooks can be used to push or pull the anterior capsular edge of the zonular dialysis for protection and avoidance of further zonular damage. This strategy provides satisfactory effects and reduces use of additional instruments.

“…Iris hooks can be valuable not only in small pupil cases but also in the setting of iris prolapse, IFIS, iridoschisis, and even for capsular support in cases with zonular dehiscence or subluxed crystalline lens [14–18].…”

“…Nevertheless, the threshold of pupil size to perform phacoemulsification without seeking for further dilation with mechanical dilations devices is subjective and can vary based on the level of the surgeon's experience. However, pupil expansion devices can be very valuable not only in small pupil cases but also in the setting of iris prolapse, intraoperative floppy iris syndrome (IFIS), iridoschisis, and for capsular support in cases with zonular dehiscence or subluxed crystalline lens [14][15][16][17][18].…”

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.
