“…SBT technique creates free suture ends while tieing the threads on the IOL's haptics. Although it is not reported in some studies,[ 4 15 24 ] free suture ends may provoke iris chafing and inflammation by rubbing on the ciliary body and iris. Cow-hitch knots have been proposed to avoid this problem.…”

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.

“…Sutured sulcus scleral fixation of Toric IOLs are already reported as treatment for dislocated in-the-capsular-beg lens [7][8][9] as well as for recurrent intraocular lens rotation 10 ; however, the long-term stability of this technique remains unknown.…”

Purpose To describe the use of toric trans-plugs IOL to correct aphakia with significant corneal astigmatism. Methods Case report and literature review. Results A 62-year-old man with an history of aphakia in his left eye after a traumatic cataract extraction and significant corneal astigmatism was referred to our clinic. Surgery plan was cataract remnants removal and secondary IOL implantation of toric sutureless trans-scleral plugs fixated IOL (FIL SSF, Soleko, Italy). The postoperative course was uneventful. At 12 months, the IOL was well-centered and the optic alignment remained stable with minimal total astigmatism. The e uncorrected distance visual acuity (UDVA) was 20/25 Snellen while correct distance visual acuity (CDVA) was 20/20 with a manifest refraction of −0.25–50 40° D; the patient was satisfied by the visual outcome. Conclusion This novel toric trans-scleral plug fixated lens provides valuable outcomes also for astigmatic correction for a comprehensive correction of the aphakia in patients with poor zonular support and high expectations for postoperative visual quality

“…Pan et al recently reported a technique using polypropylene suture to scleral fixate the haptics of a single-piece acrylic IOL without eyelets (AcrySof Toric SN6AT, Alcon, Fort Worth). 10 Because the location of fixation did not align with the steep meridian in this technique, a surgically challenging 53-degree counterclockwise rotation from the toric markings was required to achieve proper alignment in the steep corneal meridian. Conversely, the eyelet-toric IOL has marks that are in linear alignment with the eyelets to facilitate radial fixation ( Figure 5 ).…”

Purpose To describe surgical technique and report short-term visual outcomes after suture-fixation of a single-piece eyelet-toric (SET) intraocular lens (IOL) for treatment of concurrent aphakia and astigmatism. Design Retrospective, noncomparative, and non-consecutive case series. Methods This was a case series of eleven eyes who underwent successful SET. Eligible eyes had loss of capsular support or aphakia with a minimum of symmetric corneal astigmatism 1.75 diopters (D). Outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), magnitude of residual refractive cylinder, and complications resulting from the SET procedure. Results Preoperative UDVA and CDVA in logMAR scale were 1.46 and 0.45, respectively. Mean preoperative keratometric and refractive cylinder were 3.67 D and 2.52D, respectively. Postoperative UDVA and CDVA were 0.51 and 0.27, respectively, three months after surgery (POM3). Residual refractive cylinder at POM3 was 0.93 D. Conclusion SET technique reduced refractive cylinder and improved UDVA and CDVA. SET may be adapted by surgeons using a readily available IOL and familiar scleral-fixation maneuvers.

Suturing technique for scleral fixation of toric intraocular lens in the traumatic aphakic eye with corneal astigmatism

Abstract: Scleral suture fixation of foldable toric intraocular lens to correct corneal astigmatism can be a safe and effective alternative technique to manage traumatic aphakic eyes that lack adequate capsular support.
