Abstract Details

Purpose:

To evaluate safety and effectiveness of using femtosecond laser in patients with intumescent white cataract

Setting:

The Filatov institute of Eye Diseases and Tissue Therapy of the National Academy of Medical Sciences of Ukraine. Odessa Ukraine

Methods:

Our study included 90 eyes of 85 patients aged 40 to 80 years. All eyes were classified as having intumescent cataracts with shallow anterior chamber (1,2±1,8mm). Visual acuity (VA) before operation was 1,3±0,1 logMar. All operations were performed using femtosecond laser (FL) (LenSx Alcon) and Centurion Vision System. In all cases, we performed: corneal incisions, 4.8 mm capsulotomy, the size of which depended on the width of the pupil and laser fragmentation of the lens. Follow-up time was 2 years after surgery

Results:

All operations proceeded without complications. The capsulotomy was completely without presence of bridges in all cases. There were not observed any radial ruptures of the anterior capsule or other complications. VA at 1 day after surgery was 0,15±0,02 logMar. In 5 patients (5,8 %) in the first 2 days after operation, diffuse corneal edema was observed. In all cases, it was possible to achieve the planned refraction by correctly positioning the IOL in the eye. One month after surgery, the diameter of the capsulotomy was less and amounted to 4,6 mm. Inspite of a reduction of capsulotomy diameter in 6 month postoperatively, the manifest refraction spherical equivalent for all eyes was -0,09±0,31 D, mean cylindrical component was -0,25±0,5 D.

Conclusions:

The use of femtosecond lasers in the complex of surgical treatment of patients with intumescent cataracts can significantly reduce the risk of intra and postoperative complications and achieve the set refractive result. Capsulotomy is performed safely, thereby achieving the correct position of the IOL in the eye
