Spontaneous Haptic Flexion and Misalignment of a New Microincisional Aspheric Intraocular Lens in the Early Postoperative Period in Two Patients.

PURPOSE: To present two cases of spontaneous haptic flexion and misalignment of a new single-piece microincisional aspheric intraocular lens (IOL) following uneventful microincisional phacoemulsification surgery and IOL implantation.

METHODS

Case reports.

RESULTS

Both patients had decreased visual acuity and significant myopia and astigmatism in their operated eye at the postoperative first month visit. On dilated biomicroscopic examination, flexion of one haptic was observed in both cases. In one of the cases, the misaligned IOL was explanted and a different posterior chamber IOL was implanted. In the other case, the misaligned IOL was repositioned.

CONCLUSIONS

Cataract surgeons should be aware of the risk for haptic flexion and misalignment of this new IOL, causing decreased visual acuity and significant refractive error in the early postoperative period. Satisfactory results can be achieved by either IOL exchange or repositioning the IOL.
