“…Spontaneous haptic disinsertion from an IOL occurs rarely, but has previously involved various types of lens models found at different implantation sites [1][2][3][4][5][6][7][8]. Our case involved a foldable acrylic 3-piece IOL that was fixated to the iris since the capsular bag and native lens had become completed dislocated, presumably as a result of his high axial myopia or from possible unreported trauma.…”

A 39-year-old man with pathologic myopia and a dislocated native lens of the right eye underwent pars plana lensectomy and implantation of an iris-fixated 3-piece MA60MA foldable acrylic intraocular lens with -5.0 diopter power. The patient presented 11 months later with spontaneous haptic disinsertion from the optic. The meniscus (concave-convex) configuration of this iris-fixated lens may have contributed to spontaneous haptic-optic disjunction. This is the first such case reported involving a negative diopter power intraocular lens.

“…Dislocation of an intraocular lens (IOL) haptic from the optic has been reported to occur during surgery, after trauma, and spontaneously [1,2]. Spontaneous dislocations are rare, with only 8 cases reported in the literature [3][4][5][6][7][8].…”

“…Dislocated intraocular lens (IOL) fragments, either fractured or deliberately cut, such as during IOL exchange, are known to cause corneal decompensation secondary to endothelial cell loss [1] , [2] , [3] , [4] . These fractures can occur with trauma, as has been reported with single-piece poly(methyl methacrylate) (PMMA) IOLs [3] , [5] , [6] , [7] , [8] . However, they have also been reported to occur during implantation.…”

PurposeTo report a case of delayed presentation of a severed acrylic single-piece intraocular lens (IOL) haptic fragment causing corneal edema after uneventful phacoemulsification surgery.ObservationsAn 85-year-old male presented with inferior corneal decompensation six months after a reportedly uneventful phacoemulsification in his left eye. A distal haptic fragment of an acrylic single-piece posterior chamber intraocular lens was found in the inferior anterior chamber angle. Intraoperative examination revealed that the dislocated fragment originated from the temporal haptic, the remainder of which was adherent to the anterior surface of the capsular bag. The clipped edge of the haptic fragment showed a clean, flat surface, suggesting it was severed by a sharp object. The findings were considered consistent with cutting of the fragment during implantation presumably from improper lens loading, improper implantation technique, or defective implantation devices.Conclusions and ImportanceThis is the first case report of a foldable acrylic intraocular lens severed during routine uncomplicated cataract surgery that was not noted at the time of the surgery or in the immediate postoperative period. Delayed presentation of severed IOL fragments should be considered in cases of late onset corneal edema post-operatively, when other causes have been ruled out. Careful implantation technique and thorough examination of the intraocular lens after implantation to assess for lens damage intraoperatively is essential to avoid such rare complications.

“…The reported cases of IOL stress fractures involve IOLs of different materials, different delivery systems, and different timing for the onset of stress fractures. [1][2][3][4][5][6][7][8][9][10][11][12] IOL stress fractures have been reported in all of the 3 most commonly used IOL materials: poly(methyl methacrylate) (PMMA), silicone, and hydrophilic and hydrophobic acrylate. Similarly, IOL stress fractures have been reported across all types of delivery methods, including forceps, unfolder, and injector or cartridge types of IOL delivery systems or methods.…”
