“…28 Torii et al compared clinical outcomes between intracapsular implantation and intrascleral fixation of the same IOL; the mean error was 0.22 ± 0.17 and 0.86 ± 0.59D, and the postoperative anterior chamber depth was 4.65 ± 0.23 and 4.98 ± 0.61 mm, respectively. 26 With our method, the IOL haptics located out-of-the-bag and fixed in the scleral tunnels might pull up the IOL optic located in-the-bag. Postoperative refraction tended toward myopia, especially in the dual haptic fixation group.…”

“…Postoperative visual function deterioration is significantly associated with IOL malpositioning and refractive errors, as well as with high-order aberrations caused by IOL tilting and decentration. 22,23,25 Many reports have found that conventional intrascleral IOL fixation 23,25,26 combined with capsulectomy and vitrectomy can result in large refractive errors and high-order aberrations. The postoperative refractive prediction error in this study was −0.68 ± 0.95 D (myopia in 78.4% of cases), and was larger in the dual haptic fixation group.…”

Purpose: To report our modified simple technique for optic capture and the clinical results of intrascleral IOL fixation preserving the lens capsule, without vitrectomy, in cases of cataract with insufficient zonular support to stabilize the intraocular lens (IOL). Patients and Methods: In 37 eyes of 25 patients with phacodonesis and two or more risk factors for progressive zonular insufficiency, we inserted a CTR to support the capsule and zonules during cataract surgery and IOL fixation; an optic was inserted into the lens capsule, and a haptic was fixed in the scleral tunnel without vitrectomy. In all cases, anterior or total vitrectomy was not needed. Results: The postoperative mean (± standard deviation) tilt and decentration of the implanted IOL did not change from 6 to 12 months (6.77 ± 3.15° to 6.33 ± 3.38° and 0.60 ± 0.30 to 0.61 ± 0.35 mm, respectively). We encountered no late IOL dislocation and no retinal complications, including retinal breaks or cystoid macular oedema, postoperatively (follow-up = 21.1 ± 5.2 months). Conclusion: Our modified techniques preclude the need for vitrectomy. If the lens capsule can be preserved using a CTR, our modified technique can be used to stabilize IOL.

“…A previous study reported an average IOL tilt of 5.21°±1.47° during in-the-bag IOL implantation in conventional cataract surgery. 15 However, we were unable to evaluate the postoperative IOL tilt due to the unavailability of anterior segment optical coherence tomography. An IOL tilt may affect visual function by causing coma aberration and astigmatism, thereby necessitating an evaluation of the amount of IOL tilt and an improvement in the technique to achieve a tilt similar to that of in-the-bag IOL implantation cases.…”

“…However, a previous study comparing intrascleral fixation with cataract surgery using the same type of in-the-bag IOL implantation technique reported that the mean absolute prediction error of intrascleral fixation was greater than that of intracapsular implantation. 15 Once the hook haptics of hsh-IOL are buried in the sclera, the fixation becomes stable However, it is difficult to move and adjust the position of the haptics. This warrants the need for future studies to develop a technique to further reduce the predicted refractive error.…”

“…We evaluated postoperative intraocular astigmatism by subtracting the value of postoperative corneal astigmatism from that of the total manifest astigmatism using the Jaffe vector analysis. 14 Similarly, surgically induced corneal astigmatism was calculated using the Jaffe's vector analysis with the auto-keratometer values. Additionally, we assessed the intraoperative and postoperative complications.…”

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/ mm 2 ) was significantly lower than the preoperative value (2316±527 cells/mm 2 ) (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.
