PURPOSE: In this study, we aimed to report on the early results of intrascleral intraocular lens (IOL) fixation using a hook-shaped haptic IOL (hsh-IOL).
PATIENTS AND METHODS: We enrolled 27 consecutive eyes of 27 patients (mean age, 74±11.4 years) who underwent intrascleral IOL fixation with an hsh-IOL and were followed-up for 3 months postoperatively. 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.
