Abstract Details

Purpose:

Aphakia is defined by the absence of the natural crystalline lens in the eye. Causes include complicated cataract surgery (surgical aphakia), trauma (dislocation/subluxation) and various heredo-familial disorders. The ideal intraocular lens in cases of aphakia without capsular support is debated. Choices include anterior chamber lenses, iris- or scleral sutured lenses, and iris-claw lenses with the latter now being used more commonly. The purpose of this study is to compare the outcomes of anterior chamber and retropupillary implantation of iris claw Artisan IOLs.

Setting:

Institute of Ophthalmology, University of Parma - Parma (Italy)

Methods:

A total of 59 eyes were included. Group A received anterior chamber Artisan IOL implantation (27 eyes). Group B received retropupillary Artisan IOL implantation (32 eyes). Preoperatively parameters like best corrected visual acuity (BCVA), intraocular pressure (IOP) and endothelial cell (EC) count were evaluated. Post-operatively, we examined patients on the 1st week, 1 month, 3 months and 6 months after operation. During the follow-up BCVA, IOP, EC count, OCT morphology and OCT macular thickness were evaluated and compared within the two groups. All complications were noted and compared.

Results:

BCVA in group A were 0.4 (0.1-0.5), 0.4 (0.2-0.5), 0.6 (0.4-0.8) and 0.7 (0.3-0.9) preoperatively, post 1 week, post 1 month, post 3 months and post 6 months, respectively. BCVA in group B were 0.014 (0.014-0.24), 0.2 (0.1-0.6), 0.6 (0.2-0.8) and 0.7 (0.3-0.9) preoperatively, post 1 week, post 1 month, post 3 months and post 6 months, respectively. Spherical equivalent in both groups was evaluated. To evaluate astigmatism the mean of the absolute value of the cylinders has been considered. Other important parameters considered in the study was endothelial cell (EC) count, intraocular pressure (IOP) and macular thickness.

Conclusions:

Both groups had a visual improvement (P=<0.001). In both groups very near to emmetropia values were reached after six months. No significant differences in IOP between the two groups were found. No significant differences in endothelial cell loss and in macular thickness were found. Astigmatism caused by corneal incision during surgery is comparable in both groups.
