Abstract Details



Purpose:

To evaluate the precision safety and reproducibility of femtosecond laser assisted anterior capsulotomy and compare it with 26G needle manual capsulorrhexis.

Setting:

Maxivision Eye Hospital

Methods:

All cases were done by 4 surgeons. The femtosecond laser capsulotomy (Group1) was done on VICTUS ( Bausch and Lomb) platform. The manual capsulorrhexis (Group 2) was done with 26G needle. The primary measured outcomes were the diameter, circularity and centration of the anterior capsulotomy. The intended capsulotomy diameter was 5.5 mm. Each group of this study comprised 31 eyes. 

Results:

 In the femtosecond group, the mean patient age was 60 +/- 10 years (34-80 yrs). The mean cataract grade was 2.6 +/- 1.1 ( grade 1 to grade 5 white/brown cataracts). In the manual group, the mean patient age was 63 +/-13years (42-90 yrs), and the mean cataract grade was 2.6 +/- 1.1 . All procedures in both groups were uneventful. DIAMETER : Using the femtosecond to perform the anterior capsulotomy resulted in a negligible deviation from the intended diameter of 5.5 mm capsulotomy. CENTRATION : Improved centration with the femtosecond technique was recorded compared with manual group. The deviation from perfect centration in femtosecond group and the manual group was 95+/- 37ṁm and 160+/-90ṁm, respectively. CIRCULARITY: The circularity achieved in the femtosecond group was 0.97 +/- 0.01 compared with 0.93+/-0.04 in the manual group. 1.0 denotes a prefect circle.

Conclusions:

Results from this study indicate this is a promising new technique. Use of femtosecond laser can provide improved control and precision, with more reproducible results compared with manual technique.
