Abstract Details

Purpose:

To assess the results of femtosecond laser capsulotomy followed by phacoemulsification and artifitial iris and IOL in-the-bag implantation.

Setting:

S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, Russia

Methods:

7 Patients (9 eyes) included in the study with traumatic aniridia and 3 patient (4 eyes) with congenital aniridia with a concurrent cataract where artificial iris (AI) and IOL were implanted in the capsular bag after FLACS. 4 patients (5 eyes) with traumatic aniridia and cataract had AI and IOL implantation in the capsular bag after manual capsulorrhexis. 3 patients undergone sulcus fixated AI and IOL in-the-bag implantation. Pretreatment was performed using LensX laser system (Alcon). Phacoemulsification was done with a Centurion Vision System (Alcon). Videoregistration was performed with an image overlay/registration system (Callisto system).

Results:

Anterior capsulotomy diameter was 6,8±0,3mm, mean deviation from planned capsulotomy size was 0,14±0,1 mm. Mean diameter of manual capsulorrhexis was 5,0±2,2 mm with asymmetry (difference between smallest and largest diameter) of 1,20±0,71 mm in comparison to anterior capsulotomy 0,16±0,12 mm (P<0.05, Paired T-test). In 3 cases after manual capsulorrhexis AI intracapsular fixation was not technically possible and AI was sulcus fixated.

Conclusions:

Femtosecond laser allowed to create anterior capsulotomy of large diameter (6,5-7,0 mm) precisely. Postoperative complication rate was higher in cases after manual capsulorrhexis as a result of added manipulations and sulcus AI implantation.
