Purpose:
To describe a case series to determine the incidence of lens opacities after posterior chamber phakic intraocular lens (IOL) implantation (STAAR Surgical, Monrovia, CA) for very high ametropias.
Design:
Retrospective, noncomparative, interventional case series.
Participants:
Fourteen eyes of 170 consecutive eyes with high ametropias in whom lens opacities developed after posterior chamber phakic IOL implant (PCPIOL).
Intervention:
Posterior chamber phakic intraocular lens implant.
Main Outcome Measures:
Lens opacity appearance, localization, and clinical course.
Results:
Fourteen eyes developed lens opacities 125 +/- 116 days after phakic IOL implant. All eyes had anterior subcapsular opacities, and two eyes also developed nuclear sclerosis. The anterior opacities did not extend posteriorly within the lens, and there were no posterior subcapsular cataracts. Seventy-one percent of opacities were first seen
Conclusions:
Lens opacities are a potential complication of phakic IOL implantation. Most lens opacities were first seen in the early postoperative period and were most likely due to surgically induced trauma. The anterior subcapsular type was most common and tended not to be rapidly progressive during the follow-up period. The presence of nuclear sclerotic cataract was visually significant and progressive. Long-term follow-up is warranted to evaluate the rate of progression and course of lens opacities after phakic IOL implant surgery.
