⁵M.D. Associate Professor, Ege University Faculty of Medicine, Department of Ophthalmology, İzmir/TURKEY Purpose: To evaluate the anatomic and functional results of iris claw lenses (ICL) in the surgical management of aphakic cases with capsular and/or zonular insufficiency.
Materials and Methods: The data of 25 eyes of 25 cases who had undergone ICL (Artisan Aphakia, Ophtec) implantation in Ege University Faculty of Medicine, Department of Ophthalmology between February 2006 and November 2008 were retrospectively evaluated. Pre- and post-operative best corrected visual acuity (BCVA) were calculated according to Logmar equivalents, and keratometry values and corneal thickness were measured. Scheimpflug camera system (Pentacam, Oculus, Wetzlar, Germany) was used to if any demonstrate the presence of tilt or dislocation of ICL and measure the central corneal thickness.
Results: A total of 0.23 Logmar equivalent (2.3 standart line) increase in post-operative BCVA was evident (p=0.019, T Test). The comparison of pre- and post-operative BCVA revealed increment in 14, decrement in 4 cases and no change in 7 cases. Post-operative keratometric astigmatism increased with a mean of 1.04 diopters (p=0.001, T Test), central corneal thickness increased approximately 1% (p=0.000, T Test). In the early post-operative period pupillary block was detected in 1, ICL tilt in 3 cystoid macular edema in 3 cases. In the late post-operative period retinal detachment in 1, cystoid macular edema in 1, graft failure due to herpetic keratitis in 1 case were experienced.
Conclusion: ICL lenses were found to have satisfactory anatomic and functional results in the treatment of aphakic cases with capsular/zonular insufficiency. Keywords : Aphakia, iris claw lens, complication, pentacam
