Sharp-edged intraocular lens design as a cause of permanent glare.
OBJECTIVE
To evaluate patients who had implantation of an acrylic intraocular lens (IOL) and reported edge glare that did not lessen with time.


METHODS
Hawthorn Eye Clinic, Kew, Victoria, Australia.


METHODS
This retrospective study comprised patients who had uneventful phacoemulsification and then reported glare that did not abate after 12 months.


RESULTS
Five patients (7 of 322 eyes; 2.2%) who received an AcrySof MA30BA IOL with a 5.5 mm optic and 1 patient (1 of 221 eyes; 0.5%) who received an AcrySof MA60BM IOL with a 6.0 mm optic reported permanent edge glare. Extensive retinal and neurological evaluations in 2 patients showed no deficits in 1 and an abnormal photopic red electroretinogram in the other. Pilocarpine 1% was used in 3 patients and gave no relief of symptoms. Two patients (3 eyes) had IOL explantation with complete resolution of glare symptoms. There was no statistical significance between the 2 types of IOLs.


CONCLUSIONS
Sharp-edged IOL designs can cause permanent intractable glare.
