Abstract
BackgroundThe opacification of the intraocular lens (IOL) can cause significant visual deterioration. It is known that opacity of hydrophobic acrylic IOLs is rare. We report 2 cases of reversible optic opacification of hydrophobic acrylic intraocular lenses (Tecnis ZCB00, Abbott), observed within 2 months after uneventful cataract surgery.Case presentationCase 1: Uneventful cataract surgery was performed on the left eye of an 86-year-old diabetic man with chronic open-angle glaucoma. A hydrophobic acrylic intraocular lens (IOL; Tecnis ZCB00, Abbott, Lake Bluff, IL) was implanted in the bag. Eye drops containing 0.5% levofloxacin and 1.0% prednisolone were used after surgery along with topical anti-glaucoma medications. At 7 weeks postoperative, cloudy, concentric IOL opacification developed, accompanied by decreased visual acuity and increased intraocular pressure. However, the opacification completely disappeared after 9 weeks.Case 2: Uneventful cataract surgery was performed on the left eye of a 72-year-old woman. A hydrophobic acrylic IOL (Tecnis ZCB00) was implanted in the bag. At 2 weeks postoperative, cloudy, concentric IOL opacification developed, accompanied by ocular discomfort. After 4 weeks, opacification and discomfort completely disappeared.ConclusionsWe observed two cases of completely reversible opacification of hydrophobic acrylic IOLs. The exact nature of the transient opacity remains unclear, but an inflammatory origin cannot be completely ruled out.
Highlights
The opacification of the intraocular lens (IOL) can cause significant visual deterioration
It is known that hydrophobic acrylic IOLs have a low incidence rate of posterior capsule opacification (PCO), discoloration and calcification compared to IOLs of different composition [1, 2]
One previous study reported that opacification of hydrophobic acrylic IOLs occurred when the IOLs were inserted in a piggyback manner [3]
Summary
The opacification of the intraocular lens (IOL) can cause significant visual deterioration. Conclusions: We observed two cases of completely reversible opacification of hydrophobic acrylic IOLs. The exact nature of the transient opacity remains unclear, but an inflammatory origin cannot be completely ruled out. Background millions of cataract surgeries using posterior chamber lens implantation are performed worldwide each year, intraocular lens (IOL) opacification remains a serious complication that can affect visual acuity. We encountered two cases of IOL opacification that developed within 2 months after hydrophobic acrylic IOL implantation (Tecnis ZCB00).
