Abstract Details

Purpose:

To measure and compare sizing and positioning parameters of femtosecond laser capsulotomy with manual continuous curvilinear capsulorrhexis (CCC)

Setting:

Laser Eye Clinic Chandigarh

Methods:

Femtosecond laser capsulotomies (AMO-catalys ) and CCC were carried out in 25 eyes of 25 patients, respectively. Multifocal Introcular lens decentration, circularity, vertical and horizontal diameters of capsulotomies, and capsule overlap were measured with imageJ software (NIH) 1 week, 1 month, and 1 year after surgery and comparison done between two groups.

Results:

Vertical diameter of CCC was statistically significantly higher in the first week and month. Significantly higher values of capsule overlap over 1 year and circularity in the first week showed more regular femtosecond capslotomies. Horizontal multifocal IOL decentration was statistically significantly higher in the CCC group over 1year.Vertical diameter showed significant correlation to the overlap in the CCC group (P< .05), Whereas no significant correlation was noted in the femtosecond group (p>.05).

Conclusions:

More precise capsulotomy sizing and centering can be achieved with femtosecond laser. Properly sized, shaped, and centred femtosecond laser capsulotomies resulted in better overlap parameters that help maintain proper positioning of the multifocal IOL
