Purpose:
To describe the use of argon laser iridoplasty following implantation of a multifocal intraocular lens (IOL) to improve visual function.
Methods:
Argon laser spots of 500-mW power, 500-μm spot diameter, and 500-ms duration were placed in the midperipheral iris in the area in which the iris was encroaching on the IOL.
Results:
Argon laser iridoplasty provided statistically significant improvement in visual function including corrected distance visual acuity (CDVA) and subjective quality of vision in 14 eyes from 11 patients. Mean CDVA improved from 0.24 (20/35 Snellen) to 0.10 (20/25 Snellen) logMAR (P<.0001), and mean subjective quality of vision improved from 2.9 to 7.5 (P<.0001).
Conclusions:
Argon laser iridoplasty should be considered in correcting visual problems associated with decentered multifocal IOLs.
