The reasons for surgery included insufficient capsular support, including IOL dislocation, aphakia, or dislocated crystalline lens. The haptic of the hsh-IOL was externalized from the eye using forceps, and the hook was buried in the scleral tunnel. We investigated the preoperative and 3-month postoperative corrected visual acuity (VA), intraocular pressure (IOP), corneal endothelial cell density, refractive prediction error, postoperative intraocular astigmatism, surgically induced astigmatism, and intraoperative and postoperative complications.Results: The mean postoperative corrected VA (logMAR, 0.083± 0.18) was significantly better than the mean preoperative value (0.42± 0.60, p=0.0007). The 3-month postoperative mean absolute prediction error was 1.00± 0.96 D. The mean IOL-induced astigmatism was 0.95± 0.70 D. Further, the mean postoperative corneal endothelial cell count (2036± 644 cells/mm2) was significantly lower than the preoperative value (2316± 527 cells/mm2) (p=0.009). No patient had a 1-month postoperative IOP < 5 mmHg or > 25 mmHg. There were no intraoperative or vision-threatening complications, such as retinal detachment, endophthalmitis, or IOL dislocation, due to postoperative haptics misalignment.Conclusion: Intrascleral IOL fixation using hsh-IOL is an effective option for eyes with insufficient capsular support.Keywords: intrascleral IOL fixation, efficacy, safety, hook-shaped haptics, visual acuity, intraocular lensYoshida NKojima TIchikawa KDove Medical Pressarticleintrascleral iol fixationefficacysafetyhook-shaped hapticsvisual acuityintraocular lens.OphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 2885-2892 (2021)
