Implantable Collamer Posterior Chamber Intraocular Lenses: A Review of Potential Complications

Abstract

The majority of reported complications after ICL implantation are cataract formation. The improvements in lens geometry and more accurate nomograms applied to the selection of the lens to be implanted, in addition to the surgeon's learning curve, might be factors in the decreased occurrence of postoperative complications reported currently.

Implantable collamer lens and femtosecond laser for myopia: comparison using an adaptive optics visual simulator

“…In this study, we did not considered factors regarding the surgeon, lens decentrations, or postoperative changes (31) , which may affect the visual outcomes of ICL.…”

Urrets-Zavalia syndrome after implantable Collamer lens placement

“…7 The mechanism of UZS is not fully understood. The most widely accepted theories are ischemia of the iris, acute rise in IOP, and presence of iris abnormalities, which may be more common in keratoconus.…”

“…The most widely accepted theories are ischemia of the iris, acute rise in IOP, and presence of iris abnormalities, which may be more common in keratoconus. 7 The instillation of strong mydriatics and the intraoperative contact between the iris and peripheral cornea are other presumed triggers. 7 Ischemic iris atrophy is the leading explanation for the development of UZS.…”

“…7 The instillation of strong mydriatics and the intraoperative contact between the iris and peripheral cornea are other presumed triggers. 7 Ischemic iris atrophy is the leading explanation for the development of UZS. 7 Possible causes for iris ischemia include acute postoperative increase in IOP 6,8 and viscoelastic material left in the anterior chamber angle.…”

“…7 Ischemic iris atrophy is the leading explanation for the development of UZS. 7 Possible causes for iris ischemia include acute postoperative increase in IOP 6,8 and viscoelastic material left in the anterior chamber angle. 9 However, UZS was usually reported in patients with normal IOP, 10,11,4 and none of the cases in Urrets-Zavalia's original article had elevated IOP.…”
