Long-Term Stability and Visual Outcomes of a Single-Piece, Foldable, Acrylic Intraocular Lens for Scleral Fixation

Abstract

Scleral fixation of the closed-loop, foldable, acrylic C-flex intraocular lens appeared to reduce operative time, was associated with minimal postoperative complications, and resulted in long-term visual improvement.

Transscleral fixation of single-piece foldable acrylic lens with eyelets at the optic-haptic junction

“…For this reason, serious complications after transscleral fixation of enVista IOL were rare, similar to the results of previous studies held by experienced surgeons. 3,5,7,11,16,17,25,37,38 As the visual acuity improved significantly after surgery and few postoperative refractive errors were noted, we speculate that the IOLs were well centred and stable in our study.…”

“…In addition, the small incision provides the advantage of operating in a relatively closed system that can prevent intraoperative complications such as transient hypotony and can help surgeons to operate comfortably during fixation with improved globe stability. 5,11,25 As a result, we observed no intraoperative globe instability during transscleral fixation and a low rate (7%) of postoperative transient hypotony. In addition, no serious complications related to globe instability, such as choroidal detachment or suprachoroid hemorrhage, were observed.…”

“…25 They previously reported increased stability and efficacy of transscleral fixation using a foldable acrylic IOL (C-flex, Rayner, U.K.) that has closed loop haptics and a broad haptic-optic junction. Although they reported a very low rate of IOL-related complications such as IOL dislocation (3%), the C-flex IOL has large loop haptics rather than eyelets that can potentially lead to suture slippage.…”

“…6,22,23 The transscleral fixation of PC IOL is a popular technique due to excellent postoperative visual acuity and lower rate of complications. [1][2][3]11,12,14,[24][25][26] Although transscleral fixation of a PC IOL has lower complication rate, there is still a risk for decentration, tilting, suture erosion, and dislocation. 12,25,[27][28][29] Various modified techniques and designs of IOLs have been introduced to attempt to decrease these complications.…”

It is essential that IOLs be easily handled during fixation and that they maintain their stability and well-centred position.…”
