Abstract Details

Purpose:

To evaluate the technique, efficacy, and safety of posterior iris fixation of iris-claw intraocular lens (IOLs) implantation through a scleral tunnel incision in various cases of secondary aphakia correction.

Setting:

Dept. Ophthalmology, Civil Hospital S. Maria degli Angeli Pordenone , Italy

Methods:

A secondary posterior iris fixation of the Artisan iris-claw IOL was implanted in 91 consecutive cases of eyes without capsular support :4 cases to replace an angle fixated anterior chamber IOL in association with a PK procedure or a DSAEK surgery, 21 cases for secondary aphakia post cataract surgery, 27 cases o complicated cataract with bag luxation in zonular laxity , 28 cases of pseudophaco dislocation in vitreous cavity and 11 cases of lens opacification . Post operatively we evaluated : best spectacle-corrected visual acuity (BSCVA), astigmatism, lens position, and every type of post- operative complication.

Results:

BSCVA was 20/40 or better in 67 eyes (74%) during the mean follow-up time (not less than twelve months). Mean postoperative spherical equivalent was -0.80 diopters (D; standard deviation [SD], 0.51 D) at seven months after surgery. Preoperative mean astigmatism was -1.40 D (SD, 0.65 D; range, 0.0 to -2.50 D). At twelve months after surgery, mean astigmatism was -2.5 D (SD, 0.81 D; range, -0.75 to -3.75 D). There was no significant postoperative IOP increase. Lens position, evaluated by Schempflug camera Galilei, was parallel to the iris plane. In 10 cases we found iris pigment dispersion on the cornea, and in 5 cases iridophacodonesis.

Conclusions:

Posterior iris fixation of the iris-claw IOL implantation through a scleral tunnel incision is a safe first choice procedure and an effective option for aphakic eyes without capsule support, that permits a good visual recovery.
