“…In contrast to earlier reports on scleral fixation of a modern one-piece IOL (Emanuel et al 2013;Rho et al 2015;Leung et al 2016), we found a high incidence of new UGHS in patients with scleral fixated one-piece IOL (24.2%). In the multivariate Cox regression analysis, scleral fixation of a one-piece IOL was a strong independent risk factor for developing UGHS.…”

Purpose To examine the clinical outcomes of intraocular lens (IOL) scleral fixation with the friction knot technique. Methods Retrospective case series of 152 eyes of 152 patients with inadequate capsular bag support operated with the friction knot IOL scleral fixation technique by a single surgeon. The fixated IOLs were one‐piece or three‐piece models all with open loop haptics. Main outcome measures were change in corrected distance visual acuity (CDVA) and postoperative complications. Results The mean follow‐up time was 11.7 months (median 4.9, range 0.7–64.8). The mean logarithm of the minimum angle of resolution CDVA improved from preoperative 0.77 ± 0.73 (Snellen 20/118 ± 7.3 lines) to 0.44 ± 0.56 (Snellen 20/55 ± 5.6 lines) at the final visit (p < 0.001). The main postoperative complications were ocular hypertension (30.3%), uveitis–glaucoma–hyphaema syndrome (12.5%; UGHS), vitreous haemorrhage (11.2%) and retinal detachment (8.6%). Two (1.3%) cases of suture breakage were seen. In multivariate Cox regression analysis, age under 60 years [hazard ratio (HR) = 5.41; 95% confidence interval (CI) 1.95–15.01] and scleral fixated one‐piece IOL (HR = 4.23; 95% CI 1.44–12.44) were found as significant independent risk factors for developing new UGHS. Conclusion The friction knot technique provides a firm scleral fixation. Scleral fixation may successfully be utilized in dislocated three‐piece IOLs with loop haptics. We recommend avoiding scleral fixation of one‐piece IOLs in young patients due to a high risk of UGHS.

“…The puncture point location ranges from 0.5–3 mm posterior to the corneal limbus in the literature. [ 3 4 5 16 27 28 ] The sclera was punctured 3 mm posterior to the corneal limbus instead of at a closer point to reduce the possibility of iris chafing and vitreous hemorrhage from ciliary processes, and we observed no vitreous hemorrhage in our study. We believe that puncturing the sclera more posteriorly reduces the possibility of bleeding.…”

“…[ 21 ] Some SPA IOLs have closed haptics or eyelets and spaces that facilitate suturing and make the surgery safer. [ 3 16 21 25 26 27 ] Using a cow-hitch knot with those kinds of IOLs may be less likely to irritate the iris.…”

“…[ 35 ] Many studies have described scleral fixation of different SPA acrylic IOLs with different techniques. [ 3 4 5 16 21 25 26 27 28 ] None of these eyes showed any complications, such as chronic low-grade inflammation, iris chafing, pigment dispersion, UGH syndrome, IOL decentration, or IOL tilt. Only CME was observed in three eyes,[ 3 16 ] and one of them[ 16 ] was resolved with intravitreal triamcinolone acetonide injections.…”

The procedure involved an ab-externo scleral fixation technique using a double-armed 10-0 polypropylene suture with straight needles that require no scleral flaps. The IOLs are sutured to the sclera, the free suture ends are tied to the suture loops, and they are buried together under the sclera. Forty eyes of 37 patients were included. Postoperative complications are IOL capture in five eyes (12.5%), a significant IOL tilt in one eye (2.5%), recurrent UGH (uveitis-glaucoma-hyphema) syndrome in two eyes (5%), glaucoma in three eyes (7.5%), suture exposure in two eyes (5%) and IOL drop due to haptic breakage in one eye (2.5%). The technique can be effectively used for the refixation of dislocated hydrophobic acrylic IOLs by temporary haptic externalization through a corneal incision and for the treatment of aphakia with or without penetrating keratoplasty. Surgeons should be aware of the possibility of UGH syndrome due to IOL capture, especially in young eyes.
