Iris Suture Fixation vs Iris Claw for Correction of Aphakia

Iris Suture Fixation vs Iris Claw for Aphakic Correction

Evaluate and compare the advantages and disadvantages of iris suture fixation versus iris claw of posterior chamber IOLs

The eyes were randomly divided into two groups, A and B. Group A included 25 eyes in which an iris claw lens was used; specifically, the Artisan aphakia intraocular lens (Ophtec BV, Groningen, The Netherlands), a PMMA IOL with an 8.5 mm length, 1.04 mm maximum height, and a 5.4 mm optical zone width. Group B also included 25 eyes, in which iris fixation of posterior chamber foldable IOLs was performed using a single-piece PMMA IOL. This IOL had a 6 mm optic, a total diameter of 12.75 mm, and featured one eyelet for suture fixation in each haptic. The A-constant used was 118.2.

Inclusion Criteria:

• Surgical aphakia with no capsular support, with CDVA 4/60 or better on Snellen chart including: Aphakic eyes after complicated cataract surgery, crystalline lens subluxation (Marfan syndrome, pseudoexofoliation syndrome or trauma), 2nd intervention in traumatized eyes, cases with sublaxated or dislocated IOLs.

Exclusion Criteria:

• Surgical aphakia with decompensated corneas, aphakic patients with posterior segment pathologies like cystoid macular edema, choroidal neovascular membrane, aphakic patients with insufficient iris tissue, and rubeosis iridis, aphakic patients with intractable glaucoma.
