Cataract surgery in patients previously implanted with iris-claw lenses leads to good refractive results

WARSAW, Poland — Cataract surgery in patients who have previously undergone iris-claw lens implantation leads to satisfactory refractive results with no surgically induced astigmatism, according to one speaker.

“By using a simple and accurate technique to calculate the power of the IOL for cataract surgery, we have good results,” Camille Budo, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
A series of 93 eyes of 63 patients implanted with the Artisan, Artiflex or toric Artisan IOLs (Ophtec) between 1991 and 2008 underwent cataract surgery between 2000 and 2012. The average time between phakic IOL implantation and cataract surgery was 9 years.
“Mean spherical equivalent after explantation of the lens was –3 D, ranging between –14 D and 4.4 D. At 1 year after cataract surgery, mean spherical equivalent was 0 D. If you exclude some outliers, axial length was comparable before and after cataract surgery. Mean BCVA was 20/25 with the lens in place and 20/32 after cataract surgery,” Budo said.
No postoperative surgically induced astigmatism was reported, although the Artisan lens requires a 6-mm incision for implantation and explantation. For the Artiflex, the cut is half the size.
Calculation of IOL power was performed with the phakic IOL in place.
